Article II.
GENERAL TERMS AND CONDITIONS OF THE NOTES

Section 2.01 Designation and Principal Amount.

The Notes are hereby authorized and are designated the “2.75% Exchange Convertible Senior Notes due 2034.” The Notes issued on the Issue Date pursuant to the terms of this Indenture will be in an initial aggregate principal amount of $125,000,000, which amount shall be set forth in a written order of the Company for the authentication and delivery of the Notes pursuant to Section 2.03 of the Base Indenture. In addition, the Company may from time to time, without the consent of the Holders, reopen the Indenture and issue additional Notes under the Indenture with the same terms (other than the date of issuance and, in some cases, the date from which interest will initially accrue or restrictions on the transferability of such additional Notes) as the Notes issued on the Issue Date in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes issued on the Issue Date for U.S. federal income tax purposes, such additional Notes will have a separate CUSIP number. The Notes issued on the Issue Date and any such additional Notes will be treated as a single class for all purposes under the Indenture and will vote together as one class on all matters with respect to the Notes.

Section 2.02 Maturity.

The Accreted Principal Amount of the Notes will be payable on the Maturity Date.

Section 2.03 Form and Payment.

The Notes will be issued as global notes, in fully registered book-entry form without coupons in minimum denominations of $1,000 and integral multiples of $1,000.

Principal and/or interest, if any, on the global notes representing the Notes will be made to DTC (the “Depositary”).

The global notes representing the Notes will be deposited with, or on behalf of, the Depositary and will be registered in the name of the Depositary or a nominee of the Depositary. No global note may be transferred except as a whole by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or such nominee to a successor of the Depositary or a nominee of such successor.

So long as the Depositary or its nominee is the registered owner of a global note, the Depositary or its nominee, as the case may be, will be the sole Holder of the Notes represented thereby for all purposes under the Indenture. Except as otherwise provided herein, each actual purchaser of each Note represented by a global note (“Beneficial Owner”) will not be entitled to receive physical delivery of certificated Notes and will not be considered the Holders thereof for any purpose under the Indenture, and no global note representing the Notes shall be exchangeable or transferable. Accordingly, each Beneficial Owner must rely on the procedures of the Depositary and, if such Beneficial Owner is not a participant, on the procedures of the participant through which such Beneficial Owner owns its interest in order to exercise any rights of a Holder under such global note or the Indenture.

The global notes representing the Notes will be exchangeable for certificated Notes of like tenor and terms and of differing authorized denominations aggregating a like principal amount, only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the global notes representing the Notes and a successor to the Depositary is not appointed within 90 days, (ii) the Depositary ceases to be a clearing agency registered under the Exchange Act and a successor to the Depositary is not appointed by the Company within 90 days, (iii) the Company in its sole discretion determines that the global notes representing the Notes shall be exchangeable for certificated Notes and notifies the Trustee in writing of such determination or (iv) there shall have occurred and be continuing an Event of Default under the Indenture with respect to the Notes and any Beneficial Owner requests that its Notes be issued in physical, certificated form. Upon any such exchange, the certificated Notes shall be registered in the names of the Beneficial Owners of the global notes representing the Notes, which names shall be provided by the Depositary’s relevant participants (as identified by the Depositary) to the Trustee. In such event the Company will execute, and subject to Section 2.03 of the Base Indenture, the Trustee, upon receipt of an Officers’ Certificate evidencing such determination by the Company, will authenticate and deliver the Notes in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the global notes in exchange for such global notes. Upon the exchange of the global notes for such Notes in definitive registered form without coupons, in authorized denominations, the global notes shall be cancelled by the Trustee. Such Notes in definitive registered form issued in exchange for the global notes shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee in writing. The Trustee shall deliver such Notes to the Depositary for delivery to the Persons in whose names such Notes are so registered.

To the extent applicable in the Company’s determination, the Notes initially issued hereunder and any Additional Notes will bear the OID Legend.

Section 2.04 Interest.

The Original Principal Amount of the Notes shall bear interest at a rate equal to 2.75% per year. Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months based on the Original Principal Amount, and shall accrue from February 1, 2018, or from the most recent Interest Payment Date to which interest has been paid or duly provided upon for the Notes, as the case may be. Interest on the Original Principal Amount of the Notes shall be payable semi-annually in arrears on February 1 and August 1, commencing August 1, 2018 (each an “Interest Payment Date”), to the persons in whose names the Notes are registered at the Close of Business on January 15 and July 15 (whether or not a Business Day), as the case may be, preceding such Interest Payment Date (a “Regular Record Date”).

Payments of the Fundamental Change Repurchase Price, Repurchase Price, Redemption Price, principal, Accreted Principal Amount and interest that are not made when due will accrue interest per annum at the then-applicable interest rate plus one percent from the required payment date.

Section 2.05 Transfer, Exchange and Conversion.

In addition to its obligations under Section 2.04 of the Base Indenture, the Company shall also cause to be kept at one of the offices or agencies maintained pursuant to Section 2.04 of the Base Indenture an office in the United States where Notes may be presented for conversion (the “Conversion Agent”), transfer or exchange.

The Company initially appoints the Trustee as Paying Agent, Registrar and Conversion Agent for the Notes.

The Company reserves the right to:

(i) vary or terminate the appointment of the Registrar, Paying Agent or Conversion Agent;

(ii) appoint additional Paying Agents or Conversion Agents; or

(iii) approve any change in the office through which any Registrar or any Paying Agent or Conversion Agent acts.

The Company shall not be required to transfer or exchange any Note surrendered for repurchase or conversion except for any portion of that Note not being repurchased or converted, as the case may be.

Section 2.06 Repurchase and Cancellation.

Each of the Registrar, Paying Agent and Conversion Agent (if other than the Trustee) will forward to the Trustee any Notes surrendered to it by Holders for transfer, exchange, payment or conversion. All Notes delivered to the Trustee shall be cancelled promptly by the Trustee in the manner provided in the Base Indenture and may not be reissued or resold. No Notes shall be authenticated in exchange for any Notes cancelled, except as provided in the Base Indenture.

The Company may, to the extent permitted by law, directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through private or public tender or exchange offers or through counterparties to private agreements, including cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation, and such Notes will no longer be considered “outstanding” under the Indenture upon their repurchase.

Section 2.07 Accretion.

Schedule I hereto sets forth the Accreted Principal Amounts per $1,000 principal amount of Notes as of specified dates during the period from the Issue Date to February 6, 2023. Any reference in this Indenture to the Accreted Principal Amount as of a date on or after February 6, 2023 shall be determined based on the Accreted Principal Amount as of February 6, 2023. To the extent that a calculation of the Accreted Principal Amount is required at any given time, the Company will make such calculation determined as set forth on Schedule I, and will provide such calculations to the Trustee and the Holders.

Article III.
REDEMPTION AND REPURCHASE

Section 3.01 Redemption.

(a) [Reserved].

(b) On or after February 6, 2022, the Company may redeem any or all of the Notes (other than Notes for which the Company repurchase right provided under Section 3.02 have been exercised on or before the Close of Business on the Business Day immediately prior to the applicable Redemption Date) (such redemption, an “Optional Redemption”) on any Business Day (a “Redemption Date”) in cash at the Redemption Price.

(c) Section 3.03 of the Base Indenture shall not apply to, and have no force and effect with respect to, the Notes and any reference to Section 3.03 of the Base Indenture with respect to the Notes shall be superseded by and references thereto shall be deemed to refer to this Section 3.01(c). The Company shall give notice of redemption not less than 30 nor more than 60 calendar days immediately preceding the Redemption Date to all Holders of Notes on the date of the redemption notice at their addresses shown in the Registrar’s books (such notice, a “Redemption Notice”), with a copy to the Trustee and the Paying Agent.

The Redemption Notice shall identify the Notes and the aggregate Original Principal Amount to be redeemed and the Accreted Principal Amount thereof as of the Redemption Date pursuant to the redemption and shall state:

(i) the Redemption Date;

(ii) the Redemption Price;

(iii) the time at which the Holders’ right to convert the Notes called for redemption will expire, which will be the close of business on the Business Day immediately preceding the Redemption Date (unless the Company defaults in the payment of the Redemption Price);

(iv) that Holders have a right to convert the Notes called for redemption, the Conversion Rate and any adjustments thereto;

(v) the names and addresses of the Paying Agent and the Conversion Agent;

(vi) the procedures a Holder must follow to convert its Notes;

(vii) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price therefor;

(viii) the CUSIP number or numbers, as the case may be, of the Notes to be redeemed; and

(ix) in case any Note is to be redeemed in part only, the portion of the principal amount thereof to be redeemed and that on and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued.

(d) Section 3.02 of the Base Indenture shall not apply to, and have no force and effect with respect to, the Notes and any reference to Section 3.02 of the Base Indenture with respect to the Notes shall be superseded by and references thereto shall be deemed to refer to this Section 3.01(d). If the Company does not redeem all of the Notes, the Trustee shall select the Notes to be redeemed in principal amounts of $1,000 or integral multiples of $1,000, from Notes then outstanding and not already redeemed as a result of having previously been called for redemption, in accordance with the procedures of the Depositary. If the Trustee selects a portion of a Holder’s Notes for partial redemption and such Holder converts a portion of such Holder’s Note, the converted portion shall be deemed to be from the portion selected for redemption to the extent that the converted portion does not exceed the portion selected for redemption. The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and the principal amount thereof to be redeemed. If any Notes are to be redeemed in part only, the Company shall issue new Notes in principal amount equal to the unredeemed principal portion thereof; provided, that the Company shall not be required to (i) issue, register the transfer of or exchange any Notes during a period beginning at the open of business 15 days before the mailing of a Redemption Notice and ending at the close of business on the earliest date on which the relevant Redemption Notice is deemed to have been given to all Holders of Notes to be redeemed or (ii) register the transfer of or exchange any Notes so selected for redemption, in whole or in part, except the unredeemed portion of any Notes being redeemed in part.

(e) [Reserved].

(f) No Notes may be redeemed if the Accreted Principal Amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Redemption Date.

(g) If, by 11:00 a.m., New York City time, on the applicable Redemption Date, the Paying Agent holds money sufficient to make payment of the Redemption Price on all the Notes or portions thereof that are to be redeemed on such Redemption Date, then (i) such Notes will cease to be outstanding, (ii) principal will cease to accrete (to the extent such principal is still accreting pursuant to this Indenture) and 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 Redemption Price and previously accrued but unpaid interest); provided, that, if the Redemption Date is after a Regular Record Date and on or prior to the immediately following Interest Payment Date, then accrued and unpaid interest on such Notes to, but excluding, such Interest Payment Date shall be paid, on such Interest Payment Date, to the Holder of record of such Notes at the close of business on such Regular Record Date without any requirement to surrender such Notes to the Paying Agent. The Paying Agent shall return to the Company, as soon as practicable and upon receipt of written instructions, any money not required for that purpose.

(h) If the Redemption Price of any Note shall not be fully and duly paid in accordance with this Section 3.01, the portion of the Redemption Price that is not so paid shall bear interest pursuant to Section 2.04, and such Note shall continue to be convertible pursuant to Article V of this Second Supplemental Indenture, until such Redemption Price and accrued interest have been paid.

Section 3.02 Repurchase at Option of Holders Upon a Fundamental Change.

(a) Upon the occurrence of a Fundamental Change prior to the Maturity Date, each Holder will have the option to require the Company to repurchase for cash (a “Fundamental Change Repurchase Right”) all or any portion of the Original Principal Amount of such Holder’s Notes that is equal to $1,000, or an integral multiple of $1,000, on the day of the Company’s choosing that is not less than 20 or more than 35 Business Days after the later of the occurrence of such Fundamental Change and the date the Company gives notice of the Fundamental Change (such day, the “Fundamental Change Repurchase Date”) at the Fundamental Change Repurchase Price.

(b) A Holder must deliver written notice (a “Fundamental Change Repurchase Notice”) of its exercise of this Fundamental Change Repurchase Right to the Paying Agent during the period between the delivery of the Fundamental Change Notice and the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date in the form set forth in the global note attached as Exhibit A to this Indenture, in each case duly completed and signed, with appropriate signature guarantee, specifying the Notes for which the Fundamental Change Repurchase Right is being exercised. If a Holder wishes to withdraw this election, it must provide a written notice of withdrawal to the Paying Agent at any time until the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date. If the Notes are not in certificated form, the notice given by each Holder (and any withdrawal notice) must comply with applicable Depositary procedures.

(c) The Company shall mail to the Trustee and to each Holder a written notice of a Fundamental Change (the “Fundamental Change Notice”) within ten Business Days after the occurrence of such Fundamental Change. This Fundamental Change Notice shall state:

(i) the events causing the Fundamental Change;

(ii) the effective date of the Fundamental Change, and whether the Fundamental Change is a Make-Whole Fundamental Change;

(iii) the last date on which a Holder may exercise the Fundamental Change Repurchase Right;

(iv) the Fundamental Change Repurchase Price;

(v) the Fundamental Change Repurchase Date;

(vi) the Conversion Rate and, in the case of any conversion of the Note in connection with a Make-Whole Fundamental Change, the number of Additional Shares specified in Section 5.07 to be added to the Conversion Rate in connection with such Make-Whole Fundamental Change, and the procedures required for exercise of a Holder’s right to convert its Notes, including in the event of a Make-Whole Fundamental Change;

(vii) the procedures required for exercise of the Fundamental Change Repurchase Right, and the procedures required for withdrawal of any such exercise; and

(viii) the name and address of the Paying Agent and Conversion Agent.

No failure of the Company to give a Fundamental Change Notice shall limit any Holder’s right pursuant hereto to exercise its Fundamental Change Repurchase Right.

(d) The Company shall be required to repurchase Notes that have been validly surrendered for repurchase and not validly withdrawn on the Fundamental Change Repurchase Date. The Holder will receive payment of the Fundamental Change Repurchase Price on the later of the Fundamental Change Repurchase Date and the time of book-entry transfer or the delivery of such Holder’s Notes. If the Paying Agent as of 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date holds money sufficient to pay the Fundamental Change Repurchase Price of the Notes for which a Fundamental Change Repurchase Notice has been submitted and not validly withdrawn, then:

(i) such Notes shall cease to be outstanding, principal will cease to accrete (to the extent such principal is still accreting pursuant to this Indenture) and interest will cease to accrue (whether or not book-entry transfer of the Notes is made or whether or not the Note is delivered to the Paying Agent); and

(ii) all other rights of the relevant Holders of such Notes shall terminate (other than the right to receive the Fundamental Change Repurchase Price and, if the Fundamental Change Repurchase Date is after a Regular Record Date and on or prior to the related Interest Payment Date, the right of the Holder on such Regular Record Date to receive the related interest payment).

(e) No Notes may be repurchased by the Company at the option of Holders upon a Fundamental Change if the Accreted Principal Amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Repurchase 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 Paying Agent shall promptly return to the respective Holders thereof any Notes held by it during the continuance of such an acceleration.

(f) In connection with any Fundamental Change Repurchase Right, the Company shall, to the extent applicable:

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

(ii) file a Schedule TO or any successor or similar schedule, if required, under the Exchange Act; and

(iii) otherwise comply with all applicable federal and state securities laws.

Section 3.03 Repurchase at Option of Holders Upon Specified Dates.

(a) Each Holder will have the option to require the Company to repurchase all or a portion of the Original Principal Amount of their Notes for cash (“Repurchase Right”) on February 6, 2023, February 6, 2026, and February 6, 2029 (each a “Repurchase Date” and together, the “Repurchase Dates”) at the Repurchase Price. The Repurchase Price will be payable in cash and the Company will be required to repurchase any outstanding Notes for which a Holder delivers a written Repurchase Notice to the Paying Agent.

(b) A Holder must deliver a written Repurchase Notice of its exercise of this Repurchase Right to the Paying Agent during the period beginning at the Open of Business on the date that is 20 Business Days prior to the Repurchase Date until the Close of Business on the Business Day immediately preceding the Repurchase Date. If a Holder wishes to withdraw this election, it must provide a written notice of withdrawal to the Paying Agent at any time until the Close of Business on the Business Day immediately preceding the Repurchase Date. If the Notes are not in certificated form, the notice given by each Holder (and any withdrawal notice) must comply with applicable Depositary procedures.

(c) The Company shall mail to the Trustee and to each Holder a written notice (the “Holder Option to Repurchase Notice”) on a date not less than 20 Business Days prior to each Repurchase Date. This Holder Option to Repurchase Notice shall state certain specified information, including:

(i) that Holders have a right to require the Company to repurchase the Notes upon satisfaction of the requirements set forth in this Section 3.03;

(ii) the Repurchase Date;

(iii) the Repurchase Price;

(iv) that Notes with respect to which a Repurchase Notice is given by a Holder may be converted pursuant to Article V of this Second Supplemental Indenture only if such Repurchase Notice has been withdrawn in accordance with this Section 3.03 or if there shall be a default in the payment of such Repurchase Price payable as herein provided;

(v) the Conversion Rate;

(vi) the names and addresses of the Paying Agent and the Conversion Agent;

(vii) the procedures a Holder must follow for exercise of the Repurchase Right and the procedures required for withdrawal of any such exercise;

(viii) that Notes to be repurchased must be surrendered to the Paying Agent to collect the Repurchase Price therefor; and

(ix) the CUSIP number or numbers, as the case may be, of the Notes to be repurchased.

No failure of the Company to give a Holder Option to Repurchase Notice shall limit any Holder’s right pursuant hereto to exercise its Repurchase Right.

(d) The Company shall be required to repurchase Notes that have been validly surrendered for repurchase and not validly withdrawn on the Repurchase Date. The Holder will receive payment of the Repurchase Price on the later of the Repurchase Date and the time of book-entry transfer or the delivery of such Holder’s Notes. If the Paying Agent as of 11:00 a.m., New York City time, on the Repurchase Date holds money sufficient to pay the Repurchase Price of the Notes for which a Repurchase Notice pursuant to this Section 3.03 has been submitted and not validly withdrawn, then:

(ii) all other rights of the relevant Holders of such Notes shall terminate (other than the right to receive the Repurchase Price and, if the Repurchase Date is after a Regular Record Date and on or prior to the related Interest Payment Date, the right of the Holder on such Regular Record Date to receive the related interest payment).

(e) No Notes may be repurchased by the Company at the option of Holders upon their exercise of a Repurchase Right if the Accreted Principal Amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Repurchase Date (except in the case of an acceleration resulting from a default by the Company in the payment of the Repurchase Price with respect to such Notes). The Paying Agent shall promptly return to the respective Holders thereof any Notes held by it during the continuance of such an acceleration.

(f) In connection with any repurchase by the Company upon a Holder’s exercise of its Repurchase Right, the Company shall, to the extent applicable:

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

(ii) file a Schedule TO or any successor or similar schedule, if required, under the Exchange Act; and

(iii) otherwise comply with all applicable federal and state securities laws.

Section 3.04 No Sinking Fund.

No sinking fund is provided for the Notes, and Article XI of the Base Indenture is inapplicable with respect to the Notes.

Article IV.
CONSOLIDATION, MERGER AND SALE OF ASSETS

Article V of the Base Indenture shall not apply to, and have no force and effect with respect to, the Notes and any reference to Article VIII of the Base Indenture with respect to the Notes shall be superseded by and references thereto shall be deemed to refer to this Article IV.

The Company shall not consolidate with, or merge with or into, enter into any combination or binding share exchange with, another Person or sell, assign, convey, transfer, lease or otherwise dispose in one transaction or a series of transactions of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, to any successor Person unless:

(i) the successor Person, if any, is a corporation organized and existing under the laws of the United States of America or any state thereof or the District of Columbia and expressly assumes by supplemental indenture all the obligations of the Company under the Notes and the Indenture;

(ii) immediately after giving effect to the transaction, no Default or Event of Default with respect to the Notes shall have occurred and be continuing; and

(iii) the Company shall deliver to the Trustee prior to the consummation of the proposed transaction an Officers’ Certificate to the foregoing effect and an Opinion of Counsel (which may rely upon such Officers’ Certificate as to the absence of Defaults and Events of Default) stating that the proposed transaction and such supplemental indenture will, upon consummation of the proposed transaction, comply with this Indenture.

Upon any such consolidation, merger, combination, binding share exchange, or sale, assignment, conveyance, transfer, lease or other disposition, the resulting, surviving or transferee corporation (if not the Company) shall succeed to the Company, and may exercise every right and power of the Company, under this Indenture, and the Company shall be discharged from its obligations under the Notes and this Indenture except in the case of any such lease. For purposes of the foregoing, any sale, assignment, conveyance, transfer, lease or other disposition of the assets of one or more of the Company’s Subsidiaries that would, if the Company had held such assets directly, have constituted the sale, assignment, conveyance, transfer, lease or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, will be treated as such under this Indenture.

Article V.
CONVERSION OF NOTES

Section 5.01 Right to Convert.

At any time prior to the Close of Business on the Business Day immediately preceding the Maturity Date, a Holder may convert all or any portion of the Original Principal Amount of its Notes at the Conversion Rate in effect on the Conversion Date, at an initial conversion rate of 126.9438 shares of Common Stock (subject to adjustment as provided in this Article 5, the “Conversion Rate”) per $1,000 Original Principal Amount of Notes (subject to, and in accordance with, the settlement provisions of Section 5.03 and as may be increased by any Additional Shares pursuant to Section 5.07, the “Conversion Obligation”). A Holder may convert fewer than all of such Holder’s Notes so long as the Notes converted are in an integral multiple of $1,000 Original Principal Amount. Upon such conversion pursuant to this Section 5.01, the remaining Accreted Principal Amount in excess of the Original Principal Amount converted shall be deemed to be extinguished.

Section 5.02 Exchange in Lieu of Conversion.

(a) If at any time when a Holder surrenders Notes for conversion prior to the Maturity Date of the Notes, the Company:

(i) has designated a financial institution, which shall be a direct or indirect Depositary participant (a “Designated Institution”), to accept such Notes in exchange for the cash, shares of Common Stock or combination of cash and shares of Common Stock (including cash for any fractional shares) due upon conversion as provided in Section 5.03; and

(ii) notifies the Holder surrendering such Notes for conversion by the second Trading Day after the applicable Conversion Date, that it has directed the Designated Institution to make an exchange in lieu of conversion, then, notwithstanding anything in this Indenture to the contrary, the Company may direct the Conversion Agent to surrender such Notes to the Designated Institution for exchange in lieu of conversion.

(b) If the Designated Institution accepts Notes surrendered for exchange, it shall deliver the cash, shares of Common Stock or a combination of cash and shares of Common Stock (including cash for any fractional shares), to the Conversion Agent and the Conversion Agent will deliver such cash, shares of Common Stock or a combination of cash and shares of Common Stock (including cash for any fractional shares) to such Holder on the third Business Day immediately following the Conversion Date. Any Notes so exchanged by such Designated Institution shall remain outstanding for all purposes under this Indenture.

(c) If the Designated Institution agrees to accept any Notes for exchange but does not timely deliver the related consideration to the Conversion Agent, or if the Designated Institution does not accept such Notes for exchange, the Company shall, within the time period specified in Section 5.03(c), convert such Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock (including cash for any fractional shares) in accordance with the provisions of Section 5.03.

For the avoidance of doubt, in no event will the Company’s designation of a financial institution pursuant to this Section 5.02 require such financial institution to accept any Notes for exchange.

Section 5.03 Settlement upon Conversion.

(a) Subject to this Section 5.03, Section 5.06 and Section 5.07, upon conversion of any Note, the Company shall pay or deliver, as the case may be, to the converting Holder in respect of each $1,000 Original Principal Amount of Notes being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 5.03 (“Physical Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 5.03 (“Combination Settlement”), at its election, as set forth in this Section 5.03.

(i) All conversions for which the relevant Conversion Date occurs on or after August 1, 2033 shall be settled using the same Settlement Method.

(ii) Except for any conversions for which the relevant Conversion Date occurs on or after August 1, 2033, the Company shall use the same Settlement Method for all conversions occurring on the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different Conversion Dates.

(iii) If, in respect of any Conversion Date (or the period described in the third immediately succeeding set of parentheses, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company shall deliver such Settlement Notice to converting Holders (with a copy to the Trustee and the Conversion Agent) no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions for which the relevant Conversion Date occurs on or after August 1, 2033, no later than the close of business on Scheduled Trading Day immediately preceding August 1, 2033). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Combination Settlement with respect to such conversion or during such period and the Company shall be deemed to have elected Physical Settlement in respect of its Conversion Obligation. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000 Original Principal Amount of Notes. 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 Original Principal Amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 Original Principal Amount of Notes shall be deemed to be $1,000.

(iv) 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 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 Original Principal Amount of Notes being converted a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date;

(B) if the Company elects 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 Original Principal Amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 30 consecutive Trading Days during the related Observation Period; and

(C) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 Original Principal Amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 30 consecutive Trading Days during the related Observation Period.

(v) 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) 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.

(vi) At any time prior to August 1, 2033, the Company may irrevocably elect Cash Settlement to satisfy its Conversion Obligation in respect of Notes to be converted after the date of such election, or irrevocably elect Combination Settlement and a Specified Dollar Amount (which amount shall be at least $1,000 per $1,000 Original Principal Amount of Notes) to satisfy its Conversion Obligation in respect of Notes to be converted after the date of such election, or irrevocably elect Physical Settlement to satisfy its Conversion Obligation in respect of Notes to be converted after the date of such election. Upon making any election pursuant to this Section 5.03(a)(vi), the Company shall promptly (A) use its reasonable efforts to post information relating to such election on its website or otherwise publicly disclose such information, and (B) give written notice of such election to the Holders of the Notes.

(b) Subject to Section 5.03(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall (i) in the case of a global note, 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 5.03(h) and (ii) in the case of a certificated 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) 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, (3) if required, furnish appropriate endorsements and transfer documents and (4) 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 5.03(h). The Trustee (and, if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 5 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 3.02.

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 thereby) 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 subsection (b) above. The Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the third Business Day immediately following the last Trading Day of the relevant Observation Period, in the case of Cash Settlement or Combination Settlement, unless such Conversion Date occurs following the Regular Record Date immediately preceding the Maturity Date, in which case the Company shall make such delivery (and payment, if applicable) of the consideration due in respect of the Conversion Obligation on the Maturity Date. If any shares of Common Stock 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 shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

(d) 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 the Company or Trustee, 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) 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 any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall be required to pay that tax. The Conversion Agent may refuse to deliver or refuse to instruct the stock transfer agent to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence.

(f) Except as provided in Section 5.05, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion of any Note as provided in this Article 5.

(g) 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.

(h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount (and Accreted Principal Amount) of the Note and accrued and unpaid interest, if any, to, but excluding, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but excluding, the relevant Conversion Date shall be deemed to be paid in full rather than canceled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date and prior to the open of business on the corresponding Interest Payment 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; (2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; (3) if the Company has specified an Issuer’s Conversion Date that is after a Regular Record Date and on or prior to the Business Day immediately following 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 Fundamental Change Repurchase Date as described in the immediately preceding sentence shall receive the full interest payment due on the Maturity Date or other applicable Interest Payment Date regardless of whether their Notes have been converted following such Regular Record Date.

(i) The Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion.

(j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP for 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 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 relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash.

Section 5.04 Conversion Procedures.

(a) (1) If a Note is represented by a certificated security, to exercise its right of conversion, a Holder must:

(i) complete and manually sign the Conversion Notice, with the appropriate signature guarantee, or facsimile of the Conversion Notice and deliver the completed Conversion Notice (which shall be irrevocable) to the Conversion Agent;

(ii) surrender the certificated Note to the Conversion Agent;

(iii) furnish appropriate endorsements and transfer documents if required by the Registrar or Conversion Agent;

(iv) pay all transfer or similar taxes if required pursuant to Section 5.03(e); and

(v) pay all funds equal to interest payable on the next Interest Payment Date required by Section 5.03(b), if any, or

(2) If a Note is represented by a global security, to exercise its right of conversion, a Holder must comply with Section 5.04(a)(1)(iv) and Section 5.04(a)(1)(v) above and the Depositary’s procedures for converting a beneficial interest in a global security.

(b) If a Holder has submitted its Notes for repurchase upon a Fundamental Change or on a Repurchase Date, such Holder may only convert its Notes if it withdraws its Fundamental Change Repurchase Notice or Repurchase Notice, as the case may be, prior to the Fundamental Change Repurchase Date or the applicable Repurchase Date, pursuant to Section 3.02(b) or 3.03(b), as the case may be. If such Holder’s Notes are submitted for repurchase upon a Fundamental Change or on a Repurchase Date, such Holder’s right to withdraw its Fundamental Change Repurchase Notice or Repurchase Notice, as the case may be, and convert its Notes that are subject to repurchase will terminate at the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date or applicable Repurchase Date, as the case may be.

Section 5.05 Conversion Rate Adjustments.

The Conversion Rate shall be subject to adjustment from time to time, without duplication, upon the occurrence of any of the following events, provided, that the Company will 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 our Common Stock and solely as a result of holding the Notes, in any of the transactions described below 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 of Notes held by such Holder, divided by $1,000:

(a) If the Company issues solely shares of Common Stock as a dividend or distribution on all or substantially all of its shares of Common Stock, or if the Company subdivides or combines Common Stock, the Conversion Rate shall be adjusted based on the following formula:

where,

CR₀	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately prior to the Open of Business on the effective date of such subdivision or combination of Common Stock, as the case may be;
CR₁	=	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution, or effective date of such subdivision or combination of Common Stock, as the case may be;
OS₀	=	the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution or the effective date of such subdivision or combination of Common Stock, as the case may be; and

OS₁

the number of shares of Common Stock that would be outstanding immediately after giving effect to such dividend or distribution, or immediately after the effective date of such subdivision or combination of Common Stock, as the case may be.

Any adjustment made under this Section 5.05(a) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution or effective date of such subdivision or combination of Common Stock, as the case may be. If such dividend, distribution, subdivision or combination described in this Section 5.05(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 or to effect such subdivision or combination, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or subdivision or combination had not been announced.

(b) If an Ex-Dividend Date occurs for a distribution to all or substantially all holders of Common Stock of any rights, options or warrants entitling such holders for a period of not more than 60 calendar days from the announcement date for such distribution to subscribe for or purchase shares of Common Stock, at a price per share less than the average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the announcement date for such distribution, the Conversion Rate shall be increased based on the following formula:

where,

CR₀	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
CR₁	=	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such distribution;
OS₀	=	the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
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 Closing Sale Prices of Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the announcement date for such distribution.

Any adjustment made under this Section 5.05(b) will become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. Any increase made under this Section 5.05(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 distribution. To the extent that shares of Common Stock are not delivered after the exercise of such rights, options or warrants, the Conversion Rate shall be readjusted 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 distributed, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if the Record Date for such distribution had not occurred.

For purposes of this Section 5.05(b), in determining whether any rights, options or warrants entitle the Holders to subscribe for or purchase shares of Common Stock at a price that is less than the average of the Closing Sale Prices of the Common Stock over the applicable 10 consecutive Trading Day period and in determining the aggregate price payable for such shares of the Common Stock, there shall be taken into account any consideration the Company receives 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 in good faith by the Board of Directors.

(c) (A) If an Ex-Dividend Date occurs for a distribution (a “Relevant Distribution”) of shares of the Company’s capital stock, evidences of the Company’s indebtedness or 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 or distributions and rights, options or warrants as to which an adjustment was effected under Section 5.05(a) or Section 5.05(b) above; (ii) dividends or distributions paid exclusively in cash covered under Section 5.05(d); and (iii) Spin-Offs), then the Conversion Rate shall be increased based on the following formula:

where,

CR₀	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
CR₁	=	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such distribution;
SP₀	=	the average of the Closing 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 in good faith by the Board of Directors) of the shares of capital stock, evidences of indebtedness, assets or property or rights, options or warrants distributed with respect to each outstanding share of Common Stock as of the Open of Business on the Ex-Dividend Date for such distribution.

Any increase made under the above portion of this Section 5.05(c) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. No adjustment pursuant to the above formula will result in a decrease of the Conversion Rate. However, if such distribution is not so paid or made, the Conversion Rate shall be readjusted to be 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 “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive (without having to convert its notes), in respect of each $1,000 Original Principal Amount thereof, at the same time and upon the same terms as holders of the Common Stock, the amount and type of the Relevant Distribution that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Record Date for the distribution.

(B) With respect to an adjustment pursuant to this Section 5.05(c) where there has been an Ex-Dividend Date for 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, 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:

where,

CR₀	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for the Spin-Off;
CR₁	=	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for the Spin-Off;
FMV	=	the average of the Closing Sale Prices of the capital stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock (determined by reference to the definition of “Closing Sale Price” as if references therein to Common Stock were to such capital stock or similar equity interest) over the first 10 consecutive Trading Day period commencing on, and including, the effective date for the Spin-Off (such period, the “Valuation Period”); and
MP₀	=	the average of the Closing Sale Prices of the Common Stock over the Valuation Period.

The adjustment to the Conversion Rate under the preceding paragraph of this Section 5.05(c) shall be determined on the last day of the Valuation Period but will be given effect immediately after the Open of Business on the Ex-Dividend Date for the Spin-Off. In respect of any conversion during the Valuation Period for any Spin-Off, references within this Section 5.05(c)(B) related to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the effective date for such Spin-Off to, but excluding, the relevant Conversion Date.

(d) If an Ex-Dividend Date occurs for a cash dividend or distribution to all or substantially all holders of the outstanding Common Stock (other than any dividend or distribution in connection with the Company’s liquidation, dissolution or winding up), the Conversion Rate shall be increased based on the following formula:

where,

CR₀	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
CR₁	=	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such distribution;
SP₀	=	the average of the Closing 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
C	=	the amount in cash per share of Common Stock the Company pays, or distributes, to all or substantially all holders of the Common Stock.

Any increase made under this Section 5.05(d) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution. No adjustment pursuant to the above formula will result in a decrease of the Conversion Rate. However, if any dividend or distribution described in this Section 5.05(d) is declared but not so paid or made, the Conversion Rate shall be readjusted to 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 “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive (without having to convert its Notes) for each $1,000 Original Principal Amount of Notes, at the same time and upon the same terms as holders of shares of 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 Record Date for such cash dividend or distribution.

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange offer for the Common Stock and, if the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Closing 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 “Expiration Date”), the Conversion Rate shall be increased based on the following formula:

where,

CR₀	=	the Conversion Rate in effect immediately prior to the Open of Business on the Trading Day next succeeding the Expiration Date;
CR₁	=	the Conversion Rate in effect immediately after the Open of Business on the Trading Day next succeeding the Expiration Date;
AC	=	the aggregate value of all cash and any other consideration (as determined in good faith by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the time (the “Expiration Time”) such tender or exchange offer expires (prior to giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange offer);
OS₁	=	the number of shares of Common Stock outstanding immediately after the Expiration Time (after giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange offer); and
SP₁	=	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.

The adjustment to the Conversion Rate under this Section 5.05(e) shall be determined at the Close of Business on the tenth Trading Day immediately following, but excluding, the Expiration Date but shall be given effect at the Open of Business on the Trading Day next succeeding the Expiration Date. In respect of any conversion during the 10 Trading Days commencing on the Trading Day next succeeding the Expiration Date, references within this Section 5.05(e) to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, but excluding, the relevant Conversion Date. No adjustment pursuant to the above formula will result in a decrease of the Conversion Rate.

(f) To the extent that the Company has a rights plan in effect upon conversion of the Notes, the Holders shall receive, in addition to the Common Stock received in connection with such conversion, the rights under the rights plan, unless prior to any conversion, the rights have separated from the Common Stock, in which case the Conversion Rate will be adjusted at the time of separation as if the Company distributed to all holders of Common Stock, shares of the Company’s capital stock, evidences of indebtedness or other assets or property as described in Section 5.05(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

(g) To the extent permitted by applicable law and applicable listing rules of the Nasdaq Global Select Market and any other securities exchange on which the Company’s securities are then listed, (i) the Company is permitted to increase the Conversion Rate of the Notes by any amount for a period of at least 20 Business Days so long as the increase is irrevocable during the period and the Board of Directors determines that such increase would be in the Company’s best interest and (ii) the Company may (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of the Common Stock or rights to purchase shares of the Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar events. The Company must give at least 15 days’ prior notice of any such increase in the Conversion Rate.

(h) Adjustments to the Conversion Rate will be calculated to the nearest 1/10,000th of a share of Common Stock. Notwithstanding anything in this Section 5.05 to the contrary, the Company shall not be required to adjust the Conversion Rate unless the adjustment would result in a change of at least 1% of the Conversion Rate. However, the Company shall carry forward any adjustments that are less than 1% of the Conversion Rate and make such carried forward adjustments (1) when the cumulative net effect of all adjustments not yet made will result in a change of at least 1% of the Conversion Rate or (2) regardless of whether the aggregate adjustment is less than 1%, (i) upon any required repurchases of the Notes in connection with a Fundamental Change and (ii) upon any conversion of Notes.

(i) Whenever any provision of this Indenture requires the Company to calculate the Closing Sale Prices or the Stock Price over a span of multiple days, the Board of Directors shall make appropriate adjustments to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Record Date, the Ex-Dividend Date, the Expiration Date or the Effective Date of the event occurs, at any time during the period from which such Closing Sale Prices or Stock Prices are to be calculated.

(j) If the Company issues rights, options or warrants that are only exercisable upon the occurrence of certain triggering events, then (i) the Company will not adjust the Conversion Rate pursuant to the above provisions until the earliest of these triggering events occurs; and (ii) the Company will readjust the Conversion Rate to the extent any of these rights, options or warrants are not exercised before they expire.

(k) If the Company adjusts the Conversion Rate pursuant to the above provisions, the Company shall deliver to the Conversion Agent a certificate setting forth the Conversion Rate, detailing the calculation of the Conversion Rate and describing the facts upon which the adjustment is based.

Section 5.06 Recapitalizations, Reclassifications and Changes to the Common Stock.

(a) In the event of:

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination or changes in par value);

(ii) a consolidation, merger, combination or binding share exchange involving the Company; or

(iii) a sale, assignment, conveyance, transfer, lease or other disposition, in one transaction or a series of transactions, of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, to any Person (provided that, for the avoidance of doubt, a pledge of the Company’s assets pursuant to any agreement governing secured indebtedness shall not be deemed to be a sale, lease, transfer, conveyance or other disposition hereunder);

in each case, in which holders of outstanding Common Stock are entitled to receive cash, securities or other property for their shares of Common Stock (any such event, a “Merger Event”), the Company or the successor or purchasing company, as the case may be, shall execute with the Trustee a supplemental indenture, providing that, at and after the effective time of such transaction, Holders of each $1,000 Original Principal Amount of Notes will be entitled to convert their Notes into the type 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 transaction would have owned or been entitled to receive upon such transaction (“Reference Property”); 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 5.03 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 5.03 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 5.03 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 received in such Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property. The supplemental indenture shall also provide for anti-dilution and other adjustments that are as nearly equivalent as possible to the adjustments described under Section 5.05. If the Reference Property in respect of any such transaction includes shares of stock, securities or other property or assets of a company other than the successor or purchasing corporation, as the case may be, in such transaction, such other company shall also execute such supplemental indenture, and such supplemental indenture shall contain such additional provisions to protect the interests of the Holders, including the right of Holders to require the Company to repurchase their Notes upon a Fundamental Change as described in Section 3.02, as the Board of Directors reasonably considers necessary by reason of the foregoing. If the Notes become convertible into Reference Property, the Company shall notify the Trustee and the Conversion Agent.

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. If the holders of 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 Original 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 5.07), 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. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing of such weighted average as soon as practicable after such determination is made.

(b) 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 5.01 and Section 5.03 prior to the effective date of such Merger Event.

(d) Upon the consummation of any Merger Event, references to “Common Stock” shall be deemed to refer to any Reference Property that constitutes capital stock after giving effect to such Merger Event.

Section 5.07 Adjustment to Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or Prior to the Exercise of the Issuer’s Conversion Option Prior to February 1, 2020

(a) If (i) a Holder converts its Notes prior to the Company sending the Issuer’s Conversion Notice, prior to February 1, 2020 or (ii) a Holder elects to convert its Notes in connection with a Make-Whole Fundamental Change, then, in each case, the Conversion Rate of such Notes shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) as described below. A conversion shall be deemed to be “in connection with” a Make-Whole Fundamental Change if the Conversion Notice is received by the Conversion Agent during the period that begins on (and includes) the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Make-Whole Fundamental Change Effective Date”) and ends at the Close of Business on the Business Day immediately preceding 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 exception provided in clause (2) of the definition thereof, the 35th Trading Day immediately following the Effective Date). In the event any conversion is both (x) “in connection with” a Make-Whole Fundamental Change and (y) prior to the Company sending the Issuer’s Conversion Notice, a Holder of the Notes to be converted will only be entitled to a single increase in the Conversion Rate by Additional Shares. In the event both a Make-Whole Fundamental Change has occurred and a Holder converts its Notes prior to the Company sending the Issuer’s Conversion Option, the determination of Additional Shares in Section 5.07(b) shall be determined based upon a conversion “in connection with” a Make-Whole Fundamental Change and not based upon a conversion prior to the Company sending the Issuer’s Conversion Notice.

(b) For conversions prior to the Company sending the Issuer’s Conversion Notice, prior to February 1, 2020 and not in connection with a Make-Whole Fundamental Change, the number of Additional Shares will be increased by reference to the table below based on (i) an “Effective Date” that is the Conversion Date and (ii) a “Stock Price” that is equal to the greater of (A) $6.85 (as adjusted for events described in Section 5.07) and (B) the average of the Daily VWAPs of the Common Stock over the five (5) consecutive Trading Day period ending on last Trading Day prior to the applicable conversion date. For conversions in connection with a Make-Whole Fundamental Change, the number of Additional Shares will be increased by reference to the table below based on (i) an “Effective Date” that is the Fundamental Change Effective Date and (ii) a “Stock Price” equal to (x) the price paid per share of the Common Stock in the case of a Make-Whole Fundamental Change described in clause (2) of the definition of “Fundamental Change,” in the event that the Common Stock is acquired for cash, or (y) the average of the Closing Sale Prices of the Common Stock over the five Trading Day period ending on the Trading Day immediately preceding the Effective Date of such other Make-Whole Fundamental Change. Notwithstanding the foregoing, if any date that would otherwise be an “Effective Date” is between two Effective Dates in the table below, the “Effective Date” will be deemed to be the earlier of the two dates in the table (for example, if the date of a Make-Whole Fundamental Change is September 15, 2018, the “Effective Date” will be deemed to be August 1, 2018).

The Stock Prices set forth in the first row of the table below (i.e., column headers) and the number of Additional Shares in the table below will be adjusted as of any date on which the Conversion Rate of the Notes is adjusted pursuant to Section 5.05. The adjusted Stock Prices will equal the Stock Prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the 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 will be adjusted in the same manner and at the same time as the Conversion Rate pursuant to Section 5.05.

The following table sets forth the number of Additional Shares by which the Conversion Rate for each $1,000 Original Principal Amount of Notes shall be increased based on the Stock Price and the Effective Date:

	Stock Price
Effective Date	$2.00	$4.00	$6.00	$6.85	$7.88	$8.67	$10.00	$12.50	$15.00	$20.00	$30.00	$50.00	$100.00

Section 5.08 Reserved Shares.

The Company shall at all times reserve out of its authorized but unissued Common Stock a sufficient number of shares of Common Stock to permit the conversion, in accordance herewith, of all of the Notes (assuming, for such purposes, that at the time of computation of such number of shares, all such Notes would be converted by a single Holder).

The Company shall comply with all securities laws regulating the offer and delivery of shares of Common Stock upon conversion of the Notes and shall list such shares on each national securities exchange or automated quotation system on which the shares of Common Stock are listed on the applicable Conversion Date.

Section 5.09 Trustee Adjustment Disclaimer.

The Trustee has no duty to determine when an adjustment under this Article V should be made, how it should be made or what it should be.

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. 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 5.06 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 5.06 or to any adjustment to be made with respect thereto, but, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto The Trustee shall have no obligation to monitor the Company’s or any Holder’s compliance with Section 5.11 hereof.

(a) If at any time prior to the Maturity Date, the Closing Sale Price of the Common Stock has equaled or exceeded 110% of the Conversion Price then in effect for at least 20 Trading Days in any 30 Trading Day period (an “Issuer’s Conversion Trigger Event”), the Company may, at its option, elect to convert the Original Principal Amount of the Notes in whole but not in part (the “Issuer’s Conversion Option”) into cash, shares of Common Stock or a combination thereof, determined in accordance with Section 5.03(a) hereof, by sending (or instructing the Trustee to send) an Issuer’s Conversion Notice no later than the Open of Business on the third Business Day immediately following the Issuer’s Conversion Trigger Event.

With respect to certificated Notes, such delivery shall be by first class mail, and with respect to Notes represented by global notes, such delivery shall be pursuant to the applicable procedures of the Depositary. The Issuer’s Conversion Notice, if sent in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not any Holder receives such notice.

Each Issuer’s Conversion Notice shall state:

(i) the Issuer’s Conversion Date;

(ii) the CUSIP or similar number or numbers of the Notes being converted, and that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes;

(iii) that on and after the Issuer’s Conversion Date interest on the Notes to be converted will cease to accrue and the Notes will cease to be outstanding;

(f) The Trustee and the Conversion Agent have no duty to verify whether the Equity Conditions have been satisfied and may conclusively rely on the Officers’ Certificate delivered in connection therewith.

Section 5.11 Limitation on Beneficial Ownership Upon Conversion.

Notwithstanding anything to the contrary in this Article V, no Holder will be entitled to receive shares of Common Stock upon conversion, and any purported delivery of shares of Common Stock upon conversion of Notes shall be void and of no effect, to the extent (but only to the extent) that such receipt or delivery would cause (i) such converting Holder to become the owner of 4.9% or more of the Common Stock or (ii) percentage ownership in the Company of any owner of 4.9% or more of Common Stock to increase, unless such converting Holder has received prior approval of the Board of Directors (the “Section 382 Limitation”).

Section 6.02 Acceleration of Maturity; Rescission and Annulment.

Section 6.02 of the Base Indenture shall not apply to, and have no force and effect with respect to, the Notes and any reference to Section 6.02 of the Base Indenture with respect to the Notes shall be superseded by and references thereto shall be deemed to refer to this Section 6.02.

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

Section 6.03 Additional Interest.

Notwithstanding anything else in this Indenture to the contrary, if the Company so elects, the sole remedy under the Indenture for an Event of Default relating to (i) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the TIA any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act or (ii) the Company’s failure to comply with its reporting obligations to the Trustee and the Commission, pursuant to Section 9.01, will, for the first 270 days after the occurrence of such an Event of Default, consist exclusively of the right to receive additional interest on the Notes at an annual rate equal to 0.25% of the aggregate principal amount of the Notes for the first 90 days after the occurrence of such an Event of Default and at an annual rate equal to 0.50% of the aggregate principal amount of the Notes from the 91st day to, but not including, the 271st day thereafter (or, if applicable, the earlier date on which the Event of Default relating to the reporting obligations is cured or waived) (“Additional Interest”). Any such Additional Interest will be payable in the same manner and on the same dates as the stated interest payable on the Notes. If the Event of Default is continuing on the 271st day after an Event of Default relating to a failure to comply with the reporting obligations described above first occurs, the Notes will be subject to acceleration as provided in Section 6.02 of this Second Supplemental Indenture. The provisions of this Indenture described in this paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any other Events of Default.

In order to elect to pay Additional Interest as the sole remedy during the first 270 days after the occurrence of an Event of Default relating to the Company’s failure to comply with the reporting obligations set forth in clauses (i) or (ii) of the immediately preceding paragraph, the Company must notify in writing all Holders and the Trustee and Paying Agent of such election on or before the Close of Business on the fifth Business Day prior to the date on which such Event of Default would otherwise occur.

No Holder of the Notes shall have any right to institute any proceeding, judicial or otherwise, with respect to the Base Indenture, Second Supplemental Indenture or the Notes, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

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

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

(e) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the outstanding Notes;

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of the Base Indenture or the Second Supplemental Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under the Base Indenture or Second Supplemental Indenture, except in the manner herein provided and for the equal and ratable benefit of all Holders.

(i) the Company fails to pay the Accreted Principal Amount of or any interest on any Note when due;

(ii) the Company fails to deliver the consideration due upon conversion of any Note within the time period required by this Indenture; or

(iii) the Company fails to comply with any of the provisions of this Indenture the modification of which would require the consent of the Holder of each outstanding Note affected.

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

U.S. Bank National Association, as Trustee

Dated:		By: ________________________________
		Authorized Signatory

[Certificate of Authentication of Global Note]

REVERSE OF NOTE

This Security is one of a duly authorized issue of securities of the Company (herein called the “Notes”), issued and to be issued in one or more series under an Indenture, dated as of February 4, 2014 (herein called the “Base Indenture”), between the Company and U.S. Bank National Association, as Trustee, herein called the “Trustee” (which term includes any successor trustee under the Indenture (as defined below)), to which Indenture (as defined below) and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Company, the Trustee and the Holders and of the terms upon which the Notes are, and are to be, authenticated and delivered. The terms of the Notes include the covenants and terms established by the Second Supplemental Indenture, dated as of March 6, 2018, between the Company and the Trustee (the “Second Supplemental Indenture”, and as such Second Supplemental Indenture amends and supplements the Base Indenture, the “Indenture”), pursuant to the authority granted under the Indenture (such terms and covenants shall be referred to herein collectively with the terms and covenants set out in the Indenture that are applicable to the Notes as the “Indenture Terms”). Defined terms used herein that are not otherwise defined shall have the meanings given such terms in the Indenture Terms. This Note is one of the series designated on the face hereof, which series has an initial aggregate principal amount of $125,000,000. The Company may subsequently issue additional notes as part of this series of Notes under the Indenture; provided that if such additional notes are not fungible with the Notes initially issued under the Indenture for U.S. federal income tax purposes, such additional Notes will have a separate CUSIP number. In the event of any conflict between the terms of the Notes and the terms of the Indenture, the terms of the Indenture shall control.

1. Paying Agent and Registrar

The Company initially appoints the Trustee as Paying Agent and Registrar. The Company will give prompt written notice to the Trustee of the name and address, and any change in the name or address, of each Registrar or Paying Agent. The Company may also from time to time designate one or more co-registrars or additional paying agents and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligations to maintain a Registrar and a Paying Agent in each place so specified pursuant to Base Indenture Section 2.02.

U.S. Bank National Association, the Trustee under the Indenture, or any banking institution serving as successor Trustee thereunder, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates as if it were not Trustee.

2. Indenture

The Company will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to: Fluidigm Corporation, ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇ ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: Chief Financial Officer.

3. Redemption

The Notes are redeemable at certain times at the option of the Company in accordance with the Indenture prior to maturity. No sinking fund is provided for the Notes and the Notes will not be subject to defeasance.

Subject to the Indenture Terms, the Notes called for Optional Redemption become due on the relevant Redemption Date. The Company shall give the Redemption Notice not less than 30 nor more than 60 calendar days immediately preceding the Redemption Date to each Holder to be redeemed at its registered address. The Redemption Notice for the Notes shall state the Original Principal Amount to be redeemed and Accreted Principal Amount thereof as of the Redemption Date. On and after the Redemption Date, interest shall cease to accrue on any Notes that are redeemed. If less than all of the Notes are redeemed at any time, the Trustee shall select Notes to be redeemed in accordance with the procedures of the Depositary and the Indenture.

In the event of redemption of this Note in part only, a new Note or Notes of this series in principal amount equal to the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof, subject to Section 3.01(d) of the Second Supplemental Indenture.

4. Repurchase at Option of Holders Upon a Fundamental Change

Subject to the Indenture Terms, in the event of a Fundamental Change, each Holder of the Notes shall have the right, at the Holder’s option, to require the Company to repurchase such Holder’s Notes including any portion thereof which is $1,000 in principal amount or any integral multiple thereof on the Fundamental Change Repurchase Date at a price payable in cash equal to the Fundamental Change Repurchase Price.

5. Repurchase at Option of Holders Upon Specified Dates

Subject to the Indenture Terms, on each specified Repurchase Date, each Holder of the Notes shall have the right, at the Holder’s option, to require the Company to repurchase such Holder’s Notes including any portion thereof which is $1,000 in principal amount or any integral multiple thereof on the Repurchase Date at a price payable in cash equal to the Repurchase Price.

6. Conversion

Conversion at the Option of the Holder

Each Holder of the Notes shall have the right, at such Holder’s option, to convert all or any portion of the Original Principal Amount of its Note into cash, shares of Common Stock, or combination thereof, in accordance with Article V of the Second Supplemental Indenture. To convert a Note, a Holder must satisfy the requirements of Section 5.04 of the Second Supplemental Indenture. A Holder may convert a portion of a Note if the portion is $1,000 principal amount or an integral multiple of $1,000 principal amount.

Upon conversion of a Note, the Holder thereof shall be entitled to receive the applicable cash, shares of Common Stock, or combination thereof, payable upon conversion in accordance with Article V of the Second Supplemental Indenture, at the Conversion Rate specified in the Second Supplemental Indenture, as adjusted from time to time as provided in the Second Supplemental Indenture. Upon such conversion pursuant to this Section 6 the remaining Accreted Principal Amount in excess of the Original Principal Amount converted shall be deemed to be extinguished.

Issuer’s Optional Conversion

If at any time prior to the Maturity Date, an Issuer’s Conversion Trigger Event occurs, the Company may, at its option, elect to convert the Original Principal Amount of the Notes in whole but not in part into an amount of cash, shares of Common Stock or a combination of thereof, at the Company’s election as set forth in the Second Supplemental Indenture. Subject to the Indenture Terms, the Notes converted pursuant to the Company’s exercise of its Issuer’s Conversion Option will cease to be outstanding on the Issuer’s Conversion Date and interest shall cease to accrue on any Note. The Company shall give the Issuer’s Conversion Notice not more than 30 Trading Days but not less than 10 Trading Days prior to the Issuer’s Conversion Date.

7. Events of Default

The following constitute Events of Default: the Company fails to pay the Accreted Principal Amount of any Note when due; the Company fails to deliver the Settlement Amount owing upon conversion of any Note when due, and such failure continues for five Business Days; the Company fails to pay any interest on any Note when due, and such failure continues for 30 calendar days; the Company fails to pay the Redemption Price of any Note when due; the Company fails to pay the Repurchase Price or Fundamental Change Repurchase Price of any Note when due; the Company fails to provide timely notice of a Fundamental Change or a Make-Whole Fundamental Change in accordance with the Indenture; the Company fails to perform any other covenant required of it in the Indenture (other than a covenant or agreement a default in whose performance or whose breach is specifically dealt with in the preceding clauses of this sentence) and such failure continues for 60 calendar days after notice is given in accordance with the Indenture by the Trustee or Holders of not less than 25% in aggregate principal amounts of the outstanding Notes; (a) the Company’s failure, or the failure of any of the Company’s Significant Subsidiaries to make any payment at maturity (after giving effect to any applicable grace period) of Indebtedness, in a principal amount in excess of $15.0 million and continuance of such failure, or (b) the acceleration of Indebtedness of the Company or any of the Company’s Significant Subsidiaries in an amount in excess of $15.0 million because of a default with respect to such Indebtedness, unless such Indebtedness is discharged or such acceleration has been cured, waived, rescinded or annulled, in either case within a period of 30 days after written notice to us given in accordance with the Indenture by the Trustee or Holders of not less than 25% in aggregate principal amount of the outstanding Notes, provided, however, that if any such failure or acceleration referred to in (a) or (b) above shall cease or be cured, waived, rescinded or annulled, then the Event of Default by reason thereof shall be deemed not to have occurred; and certain events of bankruptcy, insolvency or reorganization with respect to the Company or any of the Company’s Significant Subsidiaries as provided in the Indenture. If any Event of Default occurs and is continuing (other than an Event of Default that is a result of bankruptcy, insolvency or reorganization of the Company as provided in the Indenture), the Trustee or the Holders of at least 25% in aggregate principal amount of the outstanding Notes may declare the Accreted Principal Amount of all of the Notes to be due and payable immediately. If an Event of Default occurs that is a result of bankruptcy, insolvency or reorganization of the Company as provided in the Indenture, the Accreted Principal Amount of the Notes and accrued and unpaid interest, if any, will automatically become due and payable in accordance with the Indenture.

8. Amendments and Waivers

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time outstanding. Without the consent of or notice to any Holder, the Indenture or the Notes may be amended or supplemented under the conditions specified in the Indenture, including to cure any ambiguity, omission, defect or inconsistency that does not materially adversely affect the Holders or to make any change that does not adversely affect the rights of any Holder. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes at the time outstanding, on behalf of the Holders of all of the Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holders shall be conclusive and binding upon such Holder and upon all future Holders and of any Note issued upon the registration of transfer hereof or in exchange or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

9. Company’s Payment Obligation

No reference herein to the Indenture Terms and no provision of this Note or of the Indenture shall alter or impair the obligations of the Company, which are absolute and unconditional, to pay the principal of and any interest on this Note at the times, places and rates, and in the coin or currency herein prescribed, and to perform the conversion obligations of the Company herein prescribed.

10. Denominations, Transfer, Exchange

The Notes are issuable only in registered form without coupons in minimum denominations of $1,000.00 and integral multiples of $1,000.00 in excess thereof. As provided in the Indenture and subject to certain limitations set forth therein, Notes are exchangeable for a like aggregate principal amount of Notes and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

Where Notes are presented to the Registrar with a request to register a transfer or to exchange them for an equal principal amount of Notes of this same Series, the Registrar shall register the transfer or make the exchange if its requirements for such transactions are met. To permit registrations of transfers and exchanges, the Trustee shall authenticate Notes at the Registrar’s request. No service charge shall be made for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer tax or similar governmental charge payable upon exchanges pursuant to the Indenture Terms). Neither the Company nor the Registrar shall be required (a) to issue, register the transfer of, or exchange Notes for the period beginning at the opening of business fifteen days immediately preceding the delivery of a notice of redemption of Notes selected for redemption and ending at the close of business on the day of such delivery, or (b) to register the transfer of or exchange Notes selected, called or being called for redemption as a whole or the portion being redeemed of any such Notes selected, called or being called for redemption in part.

11. No Personal Liability of Directors, Officers, Employees and Shareholders

A director, officer, employee or stockholder, as such, of the Company or any Subsidiary of the Company shall not have any liability for any obligations of the Company under the Notes, the Indenture Terms or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

12. Persons Deemed Owners

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
