From and after the Effective Time (as defined in Section 3.5), the consideration due upon conversion of any Notes shall be determined in the same manner as if each reference to any number of shares of Company Common Stock in Article 14 of the Indenture were instead a reference to the corresponding number of shares of Holding Company Common Stock that a Holder of such number of Company Common Stock equal to the Conversion Rate immediately prior to the Effective Time would have been entitled to receive upon the consummation of the Merger; provided that, at and after the Effective Time, any amount otherwise payable in cash in lieu of fractional shares of Holding Company Common Stock upon conversion of the Notes will continue to be payable as described in Section 14.02 of the Indenture. For clarity, the initial Conversion Rate from and after the Effective Time will be 60.9050 shares of Holding Company Common Stock.

Section 2.2. Additional Amendments to the Indenture. The Indenture is hereby amended as follows:

(a) Section 12.01 of the Indenture is hereby amended and restated in full to read as follows:

“Section 12.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the principal of or accrued and unpaid interest on any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company or New Holding Company in this Indenture or in any supplemental indenture or in any Note, nor because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, Officer or director or Subsidiary, as such, past, present or future, of New Holding Company, the Company or of any successor corporation, either directly or through New Holding Company, the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issuance of the Notes.”

(b) Section 14.01(b)(ii) of the Indenture is hereby amended and restated in full to read as follows:

“(ii) If, prior to the close of business on the Business Day immediately preceding July 1, 2020, New Holding Company elects to:

(A)

issue to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or

(B)

distribute to all or substantially all holders of the Common Stock the New Holding Company’s assets, securities or rights to purchase securities of New Holding Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date of announcement for such distribution,

then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) at least 50 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such Notice, each Holder may surrender all or any portion of its Notes for conversion at any time until the earlier of (i) the close of business, on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (ii) the announcement by the Company that such issuance or distribution will not take place, in each case, even if the Notes are not otherwise convertible at such time.”

“(iii) If (i) a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business on the Business Day immediately preceding July 1, 2020, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 15.02, or if New Holding Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of its assets, in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets, all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or after the date that is 50 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the Business Day after New Holding Company or the Company gives notice of such transaction) until 35 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) (x) as promptly as practicable following the date New Holding Company or the Company publicly announces such transaction but in no event less than 50 Scheduled Trading Days prior to the anticipated effective date of such transaction or (y) if New Holding Company or the Company does not have knowledge of such transaction at least 50 Scheduled Trading Days prior to the anticipated effective date of such transaction, within one

Business Day of the date upon which New Holding Company or the Company receives notice, or otherwise becomes aware, of such transaction, but in no event later than the actual effective date of such transaction.”

(d) Section 14.02(j) of the Indenture is hereby amended and restated in full to read as follows:

“(j) The Company shall not deliver 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 (or is deemed to have 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.”

(e) Sections 14.04(a), 14.04(b), 14.04(c), 14.04(d), 14.04(e), 14.04(i), 14.04(l), 14.06, 14.08 and 14.11 of the Indenture shall be amended to replace references to “the Company” with references to “New Holding Company.”

(f) Section 14.04(h) of the Indenture is hereby amended and restated in full to read as follows:

“(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.04, and to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of New Holding Company’s securities are then listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of New Holding Company’s securities are then listed, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall deliver to the Holder of each Note at its last address appearing on the Note Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.”

(g) The first paragraph of Section 14.07(a) of the Indenture is hereby amended and restated in full to read as follows:

“(a) In the case of:

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

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

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

(iv) any statutory share exchange,

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 10.01(g) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 14.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 14.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 14.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have received in such Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property.”

(h) Section 14.07(c) of the Indenture is hereby amended and restated in full to read as follows:

“(c) Neither the Company nor New Holding Company shall become a party to any Merger Event unless its terms are consistent with this Section 14.07. None of the foregoing provisions shall affect the right of a Holder 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 14.01 and Section 14.02 prior to the effective date of such Merger Event.”

(i) Section 14.10 of the Indenture is hereby amended and restated in full to read as follows:

“Section 14.10. Notice to Holders Prior to Certain Actions. In case of any:

(a) action by New Holding Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 14.04 or Section 14.11;

(b) Merger Event; or

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