ARTICLE

EFFECT OF MERGER ON CONVERSION PRIVILEGE

 

Section
2.1.      Conversion Right. 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:

    	5

    	

    

“(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.”

 

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

 

“(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 

    	6

    	

    

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:

    	7

    	

    

(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:

    	8

    	

    

“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

 

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

 

then, in each case (unless notice of such
event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be filed with the Trustee
and the Conversion Agent (if other than the Trustee) and to be delivered to each Holder at its address appearing on the Note Register,
as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating
(i) the date on which a record is to be taken for the purpose of such action by 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.”

EFFECT OF MERGER ON CONVERSION PRIVILEGE

 

Section
2.1. Conversion Right. From and after the Effective Time, 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 Holding Company Common Stock
in Article 14 of the Indenture were instead a reference to the corresponding number of shares of Guarantor Common Stock that
a Holder of such number of Holding 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 Guarantor 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 87.7032 shares of Guarantor Common Stock.

a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or
other derivatives.”

 

(d) 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 the Guarantor
in this Indenture or in any supplemental indenture, 

    	6

    	

    

any Note or any Note Guarantee, 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 the Guarantor, the Company or of any successor corporation, either directly or through the Guarantor,
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

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

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 Guarantor’s assets,
securities or rights to purchase securities of the Guarantor, 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.”

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

 

“(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

repurchase the Notes pursuant to Section 15.02, or if the Guarantor is a party to a consolidation, merger, binding share exchange,
or transfer or lease of all or substantially all of its assets, in each 

    	7

    	

    

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 the Guarantor 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 the Guarantor 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 the Guarantor 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 the Guarantor 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.”

 

(g) Section
14.02(a)(iii) of the Indenture is hereby amended to add the following as a new sentence at the end of such Section 14.02(a)(iii):

 

“In accordance
with this Section 14.02(a)(iii), the Company hereby irrevocably elects and determines Cash Settlement as the Settlement Method

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.”

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

 

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

 

(ii) if
the Stock Price is greater than $48.61 per share (subject to adjustment in the same manner as the Stock Prices set forth in the
column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate;
and

 

(iii) if
the Stock Price is less than $8.77 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column
headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate.

 

Notwithstanding the
foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 114.0143 shares of Common Stock, subject
to adjustment in the same manner as the Conversion Rate pursuant to Section 14.04.”

 

(j) 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 “the Guarantor.”

 

(k) 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 the Guarantor’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 the Guarantor’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 

    	9

    	

    

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.”

 

(l) 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 the Guarantor,

 

(iii) any
sale, lease or other transfer to a third party of the consolidated assets of the Guarantor and the Guarantor’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

    	10

    	

    

 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.”

 

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

 

“(c) Neither the
Company nor the Guarantor 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.”

 

(n) 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:

Section 14.11;

 

(b) Merger
Event; or

 

(c) voluntary

a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of
such action by the Guarantor or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, liquidation
or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of
record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Merger Event, dissolution,
liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such
action by the Guarantor or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up.”

 

(o) The
first paragraph of Section 17.03 of the Indenture is hereby amended and restated in full to read as follows:

Section 3.1. Guarantee.

 

(a) Subject
to the provisions of this Article III, the Guarantor hereby fully and unconditionally guarantees to each Holder of a Note authenticated
and delivered by the Trustee and to the Trustee and its successors and assigns that: (x) the principal of (including the Redemption
Price and the Fundamental Change Repurchase Price, if applicable), the Conversion Obligation with respect to, and interest on the
Notes shall be duly and punctually paid in full and/or performed in accordance with the terms of this Supplemental Indenture and
the Indenture when due, whether at the Maturity Date, upon declaration of acceleration, upon required repurchase, upon redemption,
upon conversion or otherwise, and interest on overdue principal and (to the extent permitted by law) any interest, if any, on the
Notes, (y) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same shall
be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at the Maturity
Date, by acceleration, required repurchase, redemption, conversion or otherwise and (z) all other obligations of the Company to
the Holders or the Trustee under this Supplemental Indenture, the Indenture or the Notes (including fees, expenses or other) shall
be duly and punctually paid in full or performed, all in accordance with the terms hereof or thereof, subject, however, in the
case of clauses (x), (y) and (z) above, to the limitations set forth in Section 3.2 hereof (the obligations set forth in this Section
3.1 collectively, the “Guarantee Obligations”). The Guarantee constitutes a general unsecured and unsubordinated
obligation of the Guarantor.

 

Failing payment when
due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantor will be obligated to pay or
perform the same immediately. The Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

 

(b) The
Guarantor hereby agrees that its obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability
of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect
to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other
circumstance which might otherwise constitute a legal or
equitable discharge or defense of a guarantor. The Guarantor hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the
Company, protest,

    	12

    	

    

 notice and all demands whatsoever and covenants that this Note Guarantee will not be discharged except by complete
performance of the obligations contained in the Notes, this Supplemental Indenture or the Indenture.

 

(c) If
any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantor or any custodian, trustee,
liquidator or other similar official acting in relation to either the Company or the Guarantor any amount paid to either the Trustee
or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

 

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

 

(e) In
case any provision of this Note Guarantee shall be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired thereby.

 

(f) Each
payment to be made by the Guarantor in respect of the Note Guarantee shall be made without set-off, counterclaim, reduction or
diminution of any kind or nature.

 

Section
3.2. Limitation on Guarantor Liability. The Guarantor, and by its acceptance of this Note Guarantee, each Holder,
hereby confirms that it is the intention of all such parties that this Note Guarantee of the Guarantor not constitute a fraudulent
transfer or conveyance for purposes of any bankruptcy, insolvency or other similar law now or hereafter in effect, the Uniform
Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to
this Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantor hereby agree that the obligations
of the Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent
and fixed liabilities of the Guarantor that are relevant under such laws, result in the obligations of the Guarantor under the
Note Guarantee not constituting a fraudulent transfer or conveyance under applicable local law.

 

Section
3.3. Execution and Delivery; Notation Not Required. To evidence the Note Guarantee set forth in Section 3.1 hereof,
the Guarantor hereby agrees that this Supplemental Indenture shall be executed on behalf of the Guarantor by one or more authorized
officers or persons holding an equivalent title. The Guarantor hereby agrees that the Note Guarantee set forth

    	13

    	

    

in Section 3.1 hereof
will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of the Note Guarantee.

 

Section
3.4. Release of Note Guarantee. Upon the satisfaction and discharge of the Indenture in accordance with Article
3 of the Indenture, the Guarantor will be released and relieved of any obligations under the Note Guarantee.

 

Section
3.5. Subrogation. The Guarantor shall be subrogated to all rights of Holders against the Company in respect of
any amounts paid by the Guarantor pursuant to the provisions of Section 3.1 hereof; provided that, if an Event of Default
has occurred and is continuing, the Guarantor shall not be entitled to enforce or receive any payments arising out of, or based
upon, such right of subrogation until all amounts then due and payable by the Company under this Indenture or the Notes shall have
been paid in full.

 

Section
3.6. Benefits Acknowledged. The Guarantor acknowledges that it will receive direct and indirect benefits from
the financing arrangements contemplated by the Indenture and that the guarantee and waivers made by it pursuant to the Note Guarantee
are knowingly made in contemplation of such benefits.
