purpose of this Indenture and (subject to Section 6.01) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section.

  
 The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or
writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date

 The ownership of Securities shall be proved exclusively by the Security Register for all purposes.

The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Securities entitled to give or take any request,
demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given or taken by Holders of Securities, provided, however, that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding
Securities on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided, however, that no such action shall be effective hereunder unless
taken on or prior to the applicable Record Expiration Date by Holders of the requisite principal amount of Outstanding Securities on such record date. Nothing in this paragraph shall prevent the Company from setting a new record date for any action
for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), nor shall anything in this paragraph be
construed to render ineffective any action taken pursuant to or in accordance with any other provision of this Indenture by Holders of the requisite principal amount of Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Record Expiration Date to be given to the Trustee in writing and to each Holder
of Securities in the manner set forth in Section 1.06.

Section 5.02, (iii) any 

  

 -19- 

 
request to institute proceedings referred to in Section 5.07(ii) or (iv) any direction referred to in Section 5.12. If any record date is set pursuant to
this paragraph, the Holders of Outstanding Securities on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date;
provided, however, that no such action shall be effective hereunder unless taken on or prior to the applicable Record Expiration Date by Holders of the requisite principal amount of Outstanding Securities on such record date. Nothing in this
paragraph shall be construed to prevent the Trustee from setting a new record date for any action (whereupon the record date previously set shall automatically and without any action by any Person be cancelled and of no effect), nor shall anything
in this paragraph be construed to render ineffective any action taken pursuant to or in accordance with any other provision of this Indenture by Holders of the requisite principal amount of Outstanding Securities on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the matter(s) to be submitted for potential action by Holders and the applicable Record Expiration
Date to be given to the Company in writing and to each Holder of Securities in the manner set forth in Section 1.06. 
  
 With respect to any record date set pursuant to this Section, the party hereto that sets such record date may designate any day as the “Record
Expiration Date” and from time to time may change the Record Expiration Date to any earlier or later day, provided, however, that no such change shall be effective unless notice of the proposed new Record Expiration Date is given to the
other party hereto in writing, and to each Holder of Securities in the manner set forth in Section 1.06, on or before the existing Record Expiration Date. If a Record Expiration Date is not designated with respect to any record date set pursuant to
this Section, the party hereto that set such record date shall be deemed to have initially designated the 180th day after such record date as the Record Expiration Date with respect thereto, subject to its right to change the Record Expiration Date
as provided in this paragraph. Notwithstanding the foregoing, no Record Expiration Date shall be later than the 180th day after the applicable record date. 
  
 Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

 SECTION 1.06. Notice to Holders; Waiver. Where this Indenture provides for notice to Holders of
any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not
later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail or receive such notice, nor any defect
in any such notice, to any particular Holder shall affect the sufficiency or validity of such notice. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon
such waiver. 
  
 In case by reason of the suspension of regular
mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

  
 Where this Indenture provides for notice to the administrative
agent under the Credit Agreement of any event by the Trustee, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, at its address as provided by the Company, not
later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. 
  
 SECTION 1.07. Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act
that is required under the Trust Indenture Act to be part of and govern this Indenture, such provision of the Trust Indenture Act shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that
may be so modified or excluded, such provision shall be deemed to be so modified or excluded, as the case may be. 
  
 SECTION 1.08. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only
and shall not affect the construction hereof. 
  
 SECTION 1.09.
Successors and Assigns. Without limiting Article VIII hereof, all covenants and agreements in this Indenture by each of the Company or Holdings shall bind their respective successors and assigns, whether so expressed or not. 
  
 SECTION 1.10. Separability Clause. In case any provision in this
Indenture or in the Securities 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. 
  
 SECTION 1.11. Benefits of Indenture. Nothing in this Indenture or in
the Securities, express or implied, shall give to any Person, other than the parties hereto and their 

  

 -21- 

 
successors hereunder and the Holders of Securities, any benefit or any legal or equitable right, remedy or claim under this Indenture. 
  
 SECTION 1.12. Governing Law. This Indenture and the Securities shall
be governed by and construed in accordance with the laws of the State of New York, without regard to the conflicts of law principles thereof. 
  
 SECTION 1.13. Legal Holidays. In any case where any Interest Payment Date, Redemption Date, Purchase Date, Fundamental Change Purchase Date or
Stated Maturity of any Security, or the last day on which a Holder of a Security has the right to convert such Security, shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Securities), payment of
interest or principal (and premium, if any) with respect to, or delivery for conversion of, such Security need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect (including with respect to
the accrual of interest) as if made on the Interest Payment Date, Redemption Date, Purchase Date, Fundamental Change Purchase Date, or at the Stated Maturity or by such last day for conversion.

 [FORM OF REVERSE] 
  

This Security is one of a duly authorized issue of securities of the Company designated as its “1 7/8% Convertible Senior Subordinated Notes due October 15, 2023” (herein called the “Securities”), limited in aggregate principal amount to
$125,000,000 (or $143,750,000 if the Initial Purchaser Option is exercised in full), issued and to be issued under an Indenture, dated as of October 31, 2003 (herein called the “Indenture”), between the Company, Holdings (as defined below)
and The Bank of New York, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. As provided in the
Indenture and subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities of any authorized denominations as requested by the Holder surrendering the same upon surrender of the
Security or Securities to be exchanged, at the Corporate Trust Office of the Trustee. The Trustee upon such surrender by the Holder will issue the new Securities in the requested denominations. 
  
 In any case where any Interest Payment Date, Redemption Date, Purchase Date,
Fundamental Change Purchase Date or Stated Maturity of any Security, or the last day on which a Holder of a Security has the right to convert such Security, shall not be a Business Day, then (notwithstanding any other provision of the Indenture or
of this Security), payment of interest or principal (and premium, if any) with respect to, or delivery for conversion of, such Security need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect
(including with respect to the accrual of interest) as if made on the Interest Payment Date, Redemption Date, Purchase Date, Fundamental Change Purchase Date, or at the Stated Maturity or by such last day for conversion. 
  
 No sinking fund is provided for the Securities. 
  
 Subject to and in compliance with the Indenture, the Securities are
redeemable at the option of the Company at any time on or after October 20, 2010, in whole or in part, upon not less than 30 nor more than 60 days’ notice to the Holders prior to the Redemption Date at a Redemption Price payable in cash equal
to 100% of the principal amount (the “Redemption Price”) together, in each case, with accrued and unpaid interest, if any, to, but excluding, the Redemption Date; provided, however, that installments of interest, if any, on
Securities whose Stated Maturity is on or prior to such Redemption Date will be payable to the Holders of such Securities, or one or more predecessor Securities, of record at the close of business on the relevant Record Dates, referred to on the
face hereof, all as provided in the Indenture. 
  
 In the event of
a redemption of the Securities, the Company will not be required (a) to register the transfer or exchange of Securities for a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities called
for such redemption or (b) to register the transfer or exchange of any Security, or portion thereof, called for redemption. 
  
 Subject to and upon compliance with the provisions of the Indenture, the Holder of this Security is entitled, at its option, to convert any Security that
is an integral multiple of $1,000 

  

 -28- 

 
into fully paid and nonassessable shares (calculated as to each conversion to the nearest 1/100th of a share) of Common Stock of United Rentals, Inc.
(“Holdings”) at the Conversion Rate, determined as hereinafter provided, in effect at the time of conversion and subject to the adjustments described below, as follows: 
  
 (1) if, on or prior to October 15, 2022, the Closing Price of the Common Stock for at least 20 Trading Days
in the period of the 30 consecutive Trading Days ending on the last Trading Day of any fiscal quarter is more than 125% of the then current Conversion Price of the Securities, then the Holder thereof will be entitled to convert such Security during
the immediately following fiscal quarter; 
  
 (2)
if, on any date after October 15, 2022, the Closing Price of the Common Stock is more than 125% of the then current Conversion Price of the Securities, then the Holder thereof will be entitled to convert such Security at all times thereafter;

  
 (3) if the Company elects to call the
Securities for redemption on or after October 20, 2010, then the Holder thereof will be entitled to convert such Security (or the portion of the Security called for redemption, if less than all) until the close of business on the Trading Day prior
to the Redemption Date; 
  
 (4) if Holdings
distributes to all or substantially all holders of Common Stock rights, options or warrants entitling them to purchase Common Stock at less than the Closing Price of the Common Stock on the last day preceding the declaration for such distribution,
except with respect to existing or future Rights Plans, then the Holder thereof will be entitled to convert such Security in the period described below; 
  
 (5) if Holdings distributes to all or substantially all holders of Common Stock cash, assets, debt securities or capital stock, which
distribution has a per share value as determined by the Board of Directors of Holdings exceeding 5% of the Closing Price of the Common Stock on the last day preceding the declaration for such distribution, then the Holder thereof will be entitled to
convert such Security in the period described below; or 
  
 (6) if the Company or Holdings becomes a party to a consolidation, merger or sale of all or substantially all of its assets where such consolidation, merger or sale of all or substantially all of its assets
constitutes a Fundamental Change or such an event occurs that would have been a Fundamental Change but for the exceptions (a) and (b) to the definition of Fundamental Change set forth in the second paragraph of such definition in the Indenture, then
the Holder thereof will be entitled to convert such Security in the period described below. 
  
 In the case of a distribution contemplated in clauses (4) and (5) above, the Company will notify Holders at least 20 days prior to the ex-dividend date for such distribution (the “Distribution Notice”). Once
the Company has given the Distribution Notice, Holders may surrender their Securities for conversion at any time until the earlier of the close of business on the last Business Day preceding the ex-dividend date or the Company’s announcement
that such distribution will not take place. If in the future Holdings adopts another Rights Plan, or amends 

  

 -29- 

 
or issues additional rights under its existing Rights Plan, Holders will not have any conversion right pursuant to clause (4) above or otherwise, solely as a
result of the issuance of Rights pursuant to the Rights Plan. Notwithstanding the foregoing, in the event of a distribution contemplated in clauses (4) and (5) above, Holders may not convert the Securities if the Holders may participate in such
distribution without converting their Securities. In the event of a consolidation, merger or sale of all or substantially all assets as contemplated in clause (6) above, the Company will notify Holders at least 20 days prior to the anticipated
closing date of such transaction (the “Merger Notice”). Once the Company has given the Merger Notice, the Holders may, in the event of such consolidation, merger or sale of all or substantially all assets, as contemplated in clause (6)
above, surrender Securities for conversion at any time from and after the date which is 15 days prior to the anticipated effective date of such transaction until the date which is 15 days after the actual effective date of such transaction.

  
 Furthermore, subject to the provisions of the Indenture, the
Holder of a Security is entitled, at its option, to convert the principal amount of this Security (or any portion thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) for the five Business Day period after any five
consecutive Trading Day period in which the average of the Trading Prices for the Securities for such five Trading Day period was less than 95% of the average Conversion Value for the Securities during such period; provided, however, that, if
on the Conversion Date, the Closing Price of shares of Common Stock is greater than the then current Conversion Price of the Securities and less than or equal to 125% of the then current Conversion Price of the Securities, a Holder surrenders
Securities for conversion and the Securities are not otherwise convertible, then such Holder will receive (i) at the Company’s option for a Conversion Date on or before October 19, 2010, cash or Common Stock with a value equal to the principal
amount of such Holder’s Securities on such Conversion Date or (ii) for a Conversion Date on or after October 20, 2010, cash equal to the principal amount of such Holder’s Securities on such Conversion Date and for such conversion the
Company will not have the option to pay in Common Stock. The Trustee will determine the average Trading Prices after being requested by the Company to do so as more fully described in the Indenture. If the Company elects to pay the Holder in Common
Stock, the Common Stock will be valued at 100% of the average Closing Price of Common Stock for the five Trading Days ending on the third Trading Day preceding the Conversion Date. 
  
 A Holder may convert this Security, subject to the terms and conditions provided above and in the Indenture, at any time on
or before the close of business on the date of Maturity (or in case the Holder hereof has exercised his right to require the Company to purchase or repurchase this Security or the Company has called this Security or such portion hereof for
redemption, until the Business Day immediately preceding (or, in the case of a repurchase upon a Fundamental Change, the second Trading Day immediately preceding), but, unless the Company defaults in making the payment due upon redemption, purchase
or repurchase, as the case may be, not after, the close of business on the Business Day immediately preceding (or, in the case of a repurchase upon a Fundamental Change, the second Trading Day immediately preceding) the Redemption Date, Purchase
Date or Repurchase Date, as the case may be) to convert this Security (or any portion of the principal amount hereof that is an integral multiple of $1,000, provided that the unconverted portion of such principal amount is $1,000 or any
integral multiple of $1,000 in excess thereof) into fully paid and nonassessable shares of Common Stock of Holdings at an initial Conversion Rate of 38.9520 shares of Common Stock for each $1,000 principal amount of 

  

 -30- 

 
Securities (or at the then current adjusted Conversion Rate if an adjustment has been made as provided in the Indenture) by surrender of this Security, duly
endorsed or assigned to the Company or in blank. 
  
 In order to
convert this Security, the Holder shall deliver the conversion notice hereon duly executed, to the Company at the Corporate Trust Office of the Trustee, or at such other office or agency of the Company, subject to any laws or regulations applicable
thereto and subject to the right of the Company to terminate the appointment of any Conversion Agent (as defined below) as may be designated by it for such purpose in the Borough of Manhattan, The City of New York, or at such other offices or
agencies as the Company may designate (each a “Conversion Agent”). 
  
 In case such surrender shall be made during the period from the close of business on any Regular Record Date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date, the
conversion notice shall be accompanied by payment in New York Clearing House or other funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of this Security then being
converted. Notwithstanding the foregoing, if this Security or portion hereof has been called for redemption on a Redemption Date, is repurchasable on a Fundamental Change Purchase Date or purchasable on a Purchase Date occurring, in any such case,
during the period from the close of business on any Regular Record Date next preceding any Interest Payment Date to the opening of business on such succeeding Interest Payment Date, and as a result, the right to convert this Security would otherwise
terminate in such period if not exercised and this Security is surrendered for conversion during such period, then the Holder of this Security on such Regular Record Date will be entitled to receive the amount of interest accruing hereon from the
Interest Payment Date next preceding the date of such conversion to such succeeding Interest Payment Date and the Holder of this Security who converts this Security or a portion hereof during such period shall not be required to pay such amount upon
surrender of this Security for conversion. 
  
 Subject to the
provisions of the preceding paragraph and, in the case of a conversion after the close of business on the Regular Record Date next preceding any Interest Payment Date and on or before the close of business on such Interest Payment Date, to the right
of the Holder of this Security (or any predecessor Security of record as of such Regular Record Date) to receive the related installment of interest to the extent and under the circumstances provided in the Indenture, no cash payment or adjustment
is to be made on conversion for interest, if any, accrued hereon from the Interest Payment Date next preceding the date of conversion, or for dividends on the Common Stock issued on conversion hereof. The Company shall thereafter deliver to the
Holder the fixed number of shares of Common Stock (together with any cash adjustment, as provided in the Indenture) into which this Security is convertible and such delivery will be deemed to satisfy the Company’s obligation to pay the
principal amount of this Security and accrued but unpaid interest to, but excluding, the Conversion Date. No fractions of shares or scrip representing fractions of shares will be issued on conversion, but instead of any fractional interest
(calculated to the nearest 1/100th of a share) the Company shall pay a cash adjustment as provided in the Indenture. 
  
 The Conversion Rate is subject to adjustment as provided in the Indenture. 
  

 -31- 

 In addition, the Indenture provides that in case of certain consolidations or mergers to which Holdings
is a party or the conveyance, transfer or sale of all or substantially all of the property and assets of Holdings, the Indenture shall be amended, without the consent of any Holders of Securities, so that this Security, if then Outstanding, will be
convertible thereafter, during the period this Security shall be convertible as specified above, only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, transfer or sale by a
holder of the number of shares of Common Stock of Holdings into which this Security could have been converted immediately prior to such consolidation, merger, conveyance, transfer or sale (assuming such holder of Common Stock is not a Constituent
Person or an Affiliate of a Constituent Person, failed to exercise any rights of election and received per share the kind and amount received per share by a plurality of Non-electing Shares). 
  
 If this Security is a Registrable Security (as defined in the Indenture),
then the Holder of this Security [if this security is a global security, then insert — (including any Person that has a beneficial interest in this Security)] and the Common Stock of Holdings issuable upon conversion hereof is entitled
to the benefits of a Registration Rights Agreement, dated as of October 31, 2003, between the Company and the Initial Purchasers (the “Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, the Company and Holdings
have agreed for the benefit of the Holders from time to time of the Registrable Securities that they will, at their expense, (a) within 90 days after the Issue Date, file a shelf registration statement (the “Shelf Registration Statement”)
with the Commission with respect to resales of the Registrable Securities, (b) use their best efforts to cause such Shelf Registration Statement to be declared effective by the Commission within 180 days after the Issue Date of the Securities and
(c) use their best efforts to maintain the effectiveness of such Shelf Registration Statement under the Securities Act until the second anniversary of the Issue Date of the Securities, or such earlier date as provided in the Registration Rights
Agreement (the “Effectiveness Period”). The Company will be permitted to suspend the use of the prospectus that is part of the Shelf Registration Statement during certain periods of time as provided in the Registration Rights Agreement.

  
 If (i) on or prior to 90 days following the Issue Date, a
Shelf Registration Statement has not been filed with the Commission, (ii) on or prior to the 180th day following the Issue Date, such Shelf Registration Statement is not declared effective or (iii) after the Shelf Registration Statement has been
declared effective, such Shelf Registration Statement ceases to be effective or fails to be usable in connection with resales of the Securities and the Common Stock issuable upon conversion thereof for a period of 60 days, whether or not
consecutive, (each, a “Registration Default”), additional interest (“Additional Interest”) will accrue on the Initial Securities (as defined in the Registration Rights Agreement) including the day following such Registration
Default to but excluding the day on which all Registration Defaults have been cured. Additional Interest will be paid semi-annually in arrears, with the first semi-annual payment due on the first Interest Payment Date, as applicable, in respect of
the Initial Securities following the date on which such Additional Interest began to accrue, and will accrue at a rate per annum equal to 0.25% of the principal amount of the Initial Securities to and including the 90th day following such
Registration Default. Such interest rate will increase by an additional 0.25% per annum at the beginning of each subsequent 90-day period (or portion thereof) while a 

  

 -32- 

 
Registration Default is continuing until all Registration Defaults have been cured, up to a maximum rate of Additional Interest of 1.00% per annum.

  
 [If this Security is a Registrable Security and the Holder of
this Security [if this security is a global security, then insert — (including any Person that has a beneficial interest in this Security)] elects to sell this Security pursuant to the Shelf Registration Statement then, by its acceptance
hereof, such Holder of this Security agrees to be bound by the terms of the Registration Rights Agreement relating to the Registrable Securities which are the subject of such election.] 
  
 Whenever in this Security there is a reference, in any context, to the payment of the principal of, premium, if any, or
interest on, or in respect of, any Security, such mention shall be deemed to include mention of the payment of Additional Interest payable as described in the preceding paragraph to the extent that, in such context, Additional Interest is, was or
would be payable in respect of such Security and express mention of the payment of Additional Interest (if applicable) in any provisions of this Security shall not be construed as excluding Additional Interest in those provisions of this Security
where such express mention is not made. 
  
 If a Fundamental
Change occurs, the Holder of this Security, at the Holder’s option, shall have the right, in accordance with the provisions of the Indenture, to require the Company to repurchase this Security (or any portion of the principal amount hereof that
is at least $1,000 or an integral multiple of $1,000 in excess thereof) at a Fundamental Change Purchase Price in cash equal to 100% of the principal amount thereof plus accrued interest, if any, to the Fundamental Change Purchase Date. 

 
 Subject to and in compliance with the Indenture, the Securities are
subject to purchase at the option of the Holder on each of October 15, 2010, October 15, 2013 and October 15, 2018, in whole or in part, at 100% of the principal amount of such Securities to be repurchased, together with accrued and unpaid interest,
if any, to, but excluding, the Purchase Date; provided, however, that installments of interest, if any, on Securities whose Stated Maturity is on or prior to such Purchase Date will be payable to the Holders of such Securities, or one or more
Predecessor Securities, of record at the close of business on the relevant Record Dates, referred to on the face hereof all as provided in the Indenture. 
  
 [The following paragraph shall appear in each Global Security: 
  
 In the event of a deposit or withdrawal of an interest in this Security, including an exchange, transfer, redemption,
repurchase or conversion of this Security in part only, the Trustee, as custodian of the Depositary, shall make an adjustment on its records to reflect such deposit or withdrawal in accordance with the Applicable Procedures.] 
  

 -33- 

 [The following paragraph shall appear in each Security that is not a Global Security: 

 
 In the event of redemption, repurchase or conversion of this Security in
part only, a new Security or Securities for the unredeemed, unrepurchased or unconverted portion hereof will be issued in the name of the Holder hereof.] 
  
 If an Event of Default shall occur and be continuing, the principal of all the Securities, together with interest to the date of declaration, may be
declared due and payable in the manner and with the effect provided in the Indenture. 
  
 Under the Indenture, an Event of Default includes: 
  
 (1) default in the payment of the principal of or premium, if any, when due and payable, on any of the Securities (at the Maturity Date, upon optional redemption, required purchase or otherwise), whether or not
prohibited by the subordination provisions contained in Article XIV of the Indenture; (2) default in the payment of an installment of interest on any of the Securities, when due and payable, for 30 days, whether or not prohibited by the
subordination provisions contained in Article XIV of the Indenture; (3) default in the performance, or breach, of any covenant or agreement of the Company or Holdings under the Indenture (other than a default in the performance or breach of a
covenant or agreement which is specifically dealt with in clause (1), (2) or (4)) and such default or breach shall continue for a period of 30 days after written notice has been given in accordance with the Indenture; (4) (a) a default in the
performance or breach of the provisions of Section 8.01 or (b) the Company shall have failed to make or consummate a Fundamental Change Offer in accordance with the provisions of Section 10.06, whether or not prohibited by the subordination
provisions contained in Article XIV of the Indenture; (5) failure to deliver shares of Common Stock within 10 days after such Common Stock is required to be delivered upon conversion of a Security as provided in Article XV of the Indenture; (6)
default or defaults under one or more agreements, instruments, mortgages, bonds, debentures or other evidences of Indebtedness under which the Company, Holdings or any Subsidiary of the Company that is a “restricted subsidiary” under any
of the Other Indentures then has outstanding Indebtedness in excess of $15,000,000, individually or in the aggregate, and either (a) such Indebtedness is already due and payable in full or (b) such default or defaults have resulted in the
acceleration of the maturity of such Indebtedness; (7) one or more judgments, orders or decrees of any court or regulatory or administrative agency of competent jurisdiction for the payment of money in excess of $15,000,000, either individually or
in the aggregate, shall be entered against the Company, Holdings or any Subsidiary of the Company that is a “restricted subsidiary” under any of the Other Indentures or any of their respective properties and shall not be discharged, and
there shall have been a period of 60 days after the date on which any period for appeal has expired and during which a stay of enforcement of such judgment, order or decree, shall not be in effect; (8) certain events involving bankruptcy, insolvency
or reorganization of Holdings, the Company or any Significant Subsidiary of the Company; or (9) the Guarantee of the Securities by Holdings ceases to be in full force and effect or such Guarantee is declared to be null and void and unenforceable or
such Guarantee is found to be invalid or Holdings denies its liability thereunder. 
  

 -34- 

 If an Event of Default (other than an event of default as described in clause (8) above with respect to
the Company) occurs and is continuing, the Trustee, by notice to the Company and the administrative agent under the Credit Agreement, or the Holders of at least 25% in principal amount of the Securities then Outstanding, by notice to the Trustee,
the Company and the administrative agent under the Credit Agreement, may declare the principal, premium, if any, and accrued but unpaid interest on the Securities then Outstanding to be due and payable immediately, all as and to the extent provided
in the Indenture. If an Event of Default occurs and is continuing as a result of certain events of bankruptcy, insolvency or reorganization of the Company as described in clause (8) herein, then the principal, premium, if any, and accrued but unpaid
interest on the Securities then Outstanding shall ipso facto become due and payable immediately without any declaration or other act on the part of the Trustee or any Holder, all as and to the extent provided in the Indenture. Holders may not
enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal
amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal, premium, if any, or interest)
if it determines that withholding notice is in their interests. The Company is required to file periodic reports with the Trustee as to the absence of Default. 
  

The indebtedness evidenced by the Securities is, to the extent and in the manner provided in the Indenture, subordinate and junior in right of payment
to the prior payment in full of all Senior Indebtedness of the Company. Any Holder by accepting this Security agrees to and shall be bound by such subordination provisions and authorizes the Trustee to give them effect. In addition to all other
rights of Senior Indebtedness described in the Indenture, the Senior Indebtedness shall continue to be Senior Indebtedness and entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any
terms of any instrument relating to the Senior Indebtedness or any extension or renewal of the Senior Indebtedness. 
  
 Holdings has fully and unconditionally guaranteed, on a senior subordinated basis, to each Holder of Securities and the Trustee, the full and prompt
performance of the Company’s obligations under the Indenture and the Securities, including the payment of principal of, premium, if any, and interest on the Securities. The guarantee of the Securities by Holdings is subordinated to Senior
Indebtedness of Holdings on the same basis as the Securities are subordinated to Senior Indebtedness of the Company. 
  
 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 of the Securities under the Indenture at any time by the Company and the Trustee with the written consent of the Holders of not less than a majority in principal amount of the Securities at the time Outstanding.
The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, 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 Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security
and of any Security issued in exchange 

  

 -35- 

 
therefore or in lieu hereof whether or not notation of such consent or waiver is made upon this Security or such other Security. Certain modifications or
amendments to the Indenture require the consent of the Holders of each Outstanding Security affected.

in principal amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity and the Trustee shall have failed
to institute any such proceeding, for 45 days after receipt of such notice, request and offer of indemnity, and the Trustee, within such 45 day period, shall not have received from the Holders of a majority in principal amount of the Securities
Outstanding a direction inconsistent with such request. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof, premium if any, or interest, hereon on or after the
respective due dates expressed herein or for the enforcement of the right to convert this Security as provided in the Indenture.

sufficient to cover any tax or other governmental charge payable in connection therewith. 
  
 Prior to due presentation of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered, as the
owner thereof for all purposes, whether or not such Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

2023. Interest on the Securities shall accrue at the rate of 1 7/8% per annum and shall be payable semiannually
in arrears on each April 15 and October 15, commencing April 15, 2004 to the Holders of record of Securities at the close of business on April 1 and October 1, respectively, immediately preceding such Interest Payment Date. Interest on the
Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from October 31, 2003. Interest shall accrue at a rate of 1 7/8% per annum on any overdue principal and, to the extent permitted by law, on any overdue interest. Interest on the Securities will be computed on the basis of a 360-day year
comprised of twelve 30-day months. 
  
 The

 The Securities are redeemable at the option of the Company at any time on or after October 20, 2010, in whole or in part, subject to the conditions and as
otherwise provided in Article XI and in the form of Security set forth in Section 2.02. 
  
 The Securities shall be subject to repurchase by the Company at the option of the Holders on each of October 15, 2010, October 15, 2013 and October 15, 2018, as provided in Article XII. 
  
 The Securities shall be convertible as provided in Article XV (any city in
which any Conversion Agent is located being herein called a “Place of Conversion”). 
  
 The Registrable Securities are entitled to the benefits of the Registration Rights Agreement as provided in the form of Security set forth in Section
2.02. The Securities are entitled to the payment of Additional Interest pursuant to the Registration Rights Agreement as set forth in Section 2.02. 
  
 SECTION 3.02. Denominations. The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 principal
amount and any integral multiple thereof. 
  

 -42- 

 SECTION 3.03. Execution, Authentication, Delivery and Dating. The Securities shall be executed on
behalf of the Company by its Chairman of the Board, its Chief Executive Officer, its President or one of its Vice Presidents, its Chief Operating Officer or its Chief Financial Officer. The signature of any of these officers on the Securities may be
manual or facsimile. 
  
 Securities bearing the manual or
facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of
such Securities or did not hold such offices at the date of such Securities. 
  
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee or to its order for authentication, together with a
Company Order for the authentication and delivery of such Securities; and the Trustee in accordance with such Company Order shall authenticate and deliver such Securities as in this Indenture provided and not otherwise. 
  
 Each Security shall be dated the date of its authentication. 
  
 No Security shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. 
  
 Authentication by counterpart shall satisfy the requirements of this Section 3.03 and the requirements of the Securities. 
  
 SECTION 3.04. Temporary Securities. Pending the preparation of
definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by
their execution of such Securities. 
  
 If temporary Securities
are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the
temporary Securities at any office or agency of the Company designated pursuant to Section 10.02, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations and of a like tenor. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under
this Indenture as definitive Securities. 
  
 SECTION 3.05.
Registration, Registration of Transfer and Exchange. (a) The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register 

  

 -43- 

 
(the register maintained in such office and in any other office or agency designated pursuant to Section 10.02 being herein sometimes collectively referred
to as the “Security Register”) in which, subject to such reasonable regulations as the Company may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby
appointed the initial “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. 
  
 Subject to Section 3.12 of this Indenture, upon surrender for registration of transfer of any Security at an office or agency of the Company designated
pursuant to Section 10.02 for such purpose, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any authorized denominations and of a like
aggregate principal amount and tenor and bearing such restrictive legends as may be required by this Indenture. 
  
 At the option of the Holder, and subject to the other provisions of this Section 3.05, Securities may be exchanged for other Securities of any authorized
denominations and of a like aggregate principal amount and tenor, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, and subject to the other provisions of this Section
3.05, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
  
 All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt,
and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. 
  
 Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or his attorney duly authorized in writing. 
  
 No service charge shall be made for any registration of transfer or exchange
of Securities except as provided in Section 3.06, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities,
other than exchanges pursuant to Section 3.04, 3.12, 9.06, 11.08, 15.02 (other than where the shares of Common Stock are to be issued or delivered in a name other than that of the Holder of the Security) or in accordance with any Fundamental Change
Offer pursuant to Section 10.06, and in any such case not involving any transfer. 
  
 Neither the Company nor the Securities Registrar shall be required (i) to issue, register the transfer of or exchange any Security during a period beginning at the opening of business 15 days before the day of the
mailing of a notice of redemption of Securities selected for redemption under Section 11.05 and ending at the close of business on the day of such mailing, (ii) to register the transfer of or exchange any Security so selected for redemption in whole
or in part, except the unredeemed portion of any Security being redeemed in part or (iii) to 

  

 -44- 

 
register the transfer of any Securities other than Securities having a principal amount of $1,000 or integral multiples thereof. 
  
 (b) Certain Transfers and Exchanges. Notwithstanding
any other provision of this Indenture or the Securities, transfers and exchanges of Securities and beneficial interests in a Global Security of the kinds specified in this Section 3.05(b) shall be made only in accordance with this Section 3.05(b).

  
 (i) Restricted Global Security to
Restricted Non-Global Security. In the event that Non-global Securities are to be issued pursuant to Section 3.12(a)(ii) in connection with any transfer of Securities, such transfer may be effected only in accordance with the provisions of this
clause (b)(i) and subject to the Applicable Procedures. Upon receipt by the Trustee, as Security Registrar, of (A) a Company Order from the Company directing the Trustee, as Security Registrar, to (x) authenticate and deliver one or more Securities
of the same aggregate principal amount as the beneficial interest in the Restricted Global Security to be transferred, such instructions to contain the name or names of the designated transferee or transferees, the authorized denomination or
denominations of the Securities to be so issued and appropriate delivery instructions and (y) decrease the beneficial interest of a specified Agent Member’s account in a Restricted Global Security by a specified principal amount not greater
than the principal amount of such Restricted Global Security, and (B) such other certifications, legal opinions or other information as the Company or the Trustee may reasonably require to confirm that such transfer is being made pursuant to an
exemption from, or in a transaction not subject to, the registration requirements of the Securities Act, then the Trustee, as Security Registrar, shall decrease the principal amount of the Restricted Global Security by the specified amount and
authenticate and deliver Securities in accordance with such instructions from the Company as provided in Section 3.12(a)(iii). 
  
 (ii) Restricted Non-Global Security to Restricted Global Security. If the Holder of a Restricted Security (other than a Global
Security) wishes at any time to transfer all or any portion of such Restricted Security to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Security, such transfer may be effected only in
accordance with the provisions of this clause (b)(ii) and subject to the Applicable Procedures. Upon receipt by the Trustee, as Security Registrar, of such Restricted Security as provided in Section 3.12(a) and instructions from the Company
directing that a beneficial interest in the Restricted Global Security in a specified principal amount not greater than the principal amount of such Security be credited to a specified Agent Member’s account, then the Trustee, as Security
Registrar, shall cancel such Restricted Security (and issue a new Restricted Security in respect of any untransferred portion thereof) as provided in Section 3.12(a) and increase the principal amount of the Restricted Global Security by the
specified principal amount as provided in Section 3.12(a)(iii). 
  
 (iii) Exchanges Between Global Security and Non-Global Security. A beneficial interest in a Global Security may be exchanged for a Security that is not a Global Security only as provided in Section 3.12 or only
if such exchange occurs in connection with a transfer effected in accordance with clause (b)(i) above, provided that, if such 

  

 -45- 

 
interest is a beneficial interest in the Restricted Global Security, then such interest shall be exchanged for a Restricted Security (subject in each case to
Section 3.12(c)). A Security that is not a Global Security may be exchanged for a beneficial interest in a Global Security only if such exchange occurs in connection with a transfer effected in accordance with clause (b)(ii) above. 
  
 (c) Securities Act Legends. All Securities issued
pursuant to this Indenture, and all Successor Securities, shall bear the Restricted Securities Legend and shall be subject to the restrictions on transfer specified therein, subject to the following: 
  
 (i) subject to the following clauses of this Section 3.5(c),
a Security or any portion thereof that is exchanged, upon transfer or otherwise, for a Global Security or any portion thereof shall bear the Restricted Securities Legend borne by such Global Security for which the Security was exchanged; 

 
 (ii) subject to the following clauses of this Section
3.5(c), a new Security that is not a Global Security and is issued in exchange for another Security (including a Global Security) or any portion thereof, upon transfer or otherwise, shall bear the Restricted Securities Legend borne by the Security
for which the new Security was exchanged; 
  
 (iii) any Securities that are sold or otherwise disposed of pursuant to an effective registration statement under the Securities Act (including the Shelf Registration Statement), together with their Successor Securities shall not bear a
Restricted Securities Legend; the Company shall inform the Trustee in writing of the effective date of any such registration statement registering the Securities under the Securities Act and shall notify the Trustee at any time when prospectuses
must be delivered with respect to Securities to be sold pursuant to such registration statement. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the aforementioned registration
statement; 
  
 (iv) at any time after the
Securities may be freely transferred without registration under the Securities Act or without being subject to transfer restrictions pursuant to the Securities Act, a new Security that does not bear a Restricted Securities Legend may be issued in
exchange for or in lieu of a Security (other than a Global Security) or any portion thereof that bears such a legend if the Trustee has received an Unrestricted Securities Certificate, satisfactory to the Trustee and duly executed by the Holder of
such Security bearing a Restricted Securities Legend or his attorney duly authorized in writing, and after such date and receipt of such certificate, the Trustee shall authenticate and deliver such new Security in exchange for or in lieu of such
other Security as provided in this Article III; 
  
 (v) a new Security that does not bear a Restricted Securities Legend may be issued in exchange for or in lieu of a Security or any portion thereof that bears such a legend if, in the Company’s judgment, placing such a legend upon such
new Security is not necessary to ensure compliance with the registration requirements of the Securities Act, and the Trustee, at the direction of the Company, shall authenticate and deliver such a new Security as provided in this Article III; and

  

 -46- 

 (vi) notwithstanding the foregoing provisions of this Section 3.05(c), a Successor
Security of a Security that does not bear a Restricted Securities Legend shall not bear such legend unless the Company has reasonable cause to believe that such Successor Security is a “restricted security” within the meaning of Rule 144,
in which case the Trustee, at the direction of the Company, shall authenticate and deliver a new Security bearing a Restricted Securities Legend in exchange for such Successor Security as provided in this Article III. 
  
 (d) Any stock certificate representing shares of Common
Stock issued upon conversion of the Securities shall bear the Restricted Securities Legend borne by such Securities, to the extent required by this Indenture, unless such shares of Common Stock have been sold pursuant to a registration statement
that has been declared effective under the Securities Act (and that continues to be effective at the time of such transfer) or sold pursuant to Rule 144(k) of the Securities Act, or unless otherwise agreed by the Company in writing with written
notice thereof to the transfer agent for the Common Stock. With respect to the transfer of shares of Common Stock issued upon conversion of the Securities that are restricted hereunder, any deliveries of certificates, legal opinions or other
instruments that would be required to be made to the Security Registrar in the case of a transfer of Securities, as described above, shall instead be made to the transfer agent for the Common Stock. 
  
 (e) Neither the Trustee, the Paying Agent nor any of their
agents shall (i) have any duty to monitor compliance with or with respect to any federal or state or other securities or tax laws or (ii) have any duty to obtain documentation on any transfers or exchanges other than as specifically required
hereunder. 
  
 SECTION 3.06. Mutilated, Destroyed, Lost and
Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and principal amount and bearing a number not
contemporaneously outstanding. 
  
 If there shall be delivered to
the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of each of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute, and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
  
 In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion, but
subject to any conversion rights, may, instead of issuing a new Security, pay such Security. 
  
 Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith. 
  

 -47- 

 Every new Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security
shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder. 
  
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

  
 SECTION 3.07. Payment of Interest; Rights Preserved.
Subject to the last paragraph of this Section, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more predecessor
securities) is registered at the close of business on the Regular Record Date for such interest payment. 
  
 Any interest on any Security which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called
“Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case,
as provided in paragraph (1) or (2) below: 
  
 (1) the Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective predecessor Securities) are registered at the close of business on a Special Record Date for the payment
of such Defaulted Interest, which shall be fixed in the following manner: the Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment, and at the same
time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of
the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such
Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 15 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly
notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder in the manner
specified in Section 1.06, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the
Persons in whose names the Securities (or their respective predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

 (2) the Company may make payment of any Defaulted Interest in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to
this clause (2), such manner of payment shall be deemed practicable by the Trustee. 
  
 Subject to the foregoing provisions of this Section and Section 3.05, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption or repurchase and that reliance may be

 SECTION 3.12. Global Securities; Non-Global Securities; Book-entry Provisions. 
  
 (a) Global Securities. 
  
 (i) Each Global Security authenticated under this Indenture
shall be registered in the name of the Depositary designated by the Company for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a
single Security for all purposes of this Indenture. 
  
 (ii) Except for exchanges of Global Securities for definitive, Non-global Securities at the sole discretion of the Company, no Global Security may be exchanged in whole or in part for Securities registered, and no transfer of a Global
Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has notified the Company that it is unwilling or unable to continue as
Depositary for such Global Security or (ii) has ceased to be a clearing agency registered as such under the Exchange Act or announces an intention permanently to cease business or does in fact do so or (B) there shall have occurred and be continuing
an Event of Default with respect to such Global Security. In such event, if a successor Depositary for such Global Security is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility,
the Company will execute, and the Trustee, upon receipt of an Officers’ Certificate directing the authentication and delivery of Securities, will authenticate and deliver, Securities, in any authorized denominations in an aggregate principal
amount equal to the principal amount of such Global Security in exchange for such Global Security. 
  
 (iii) If any Global Security is to be exchanged for other Securities or canceled in whole, it shall be surrendered by or on behalf of the
Depositary or its nominee to the Trustee, as Security Registrar, for exchange or cancellation, as provided in this Article III. If any Global Security is to be exchanged for other Securities or canceled in part, or if another Security is to be
exchanged in whole or in part for a beneficial interest in any Global Security, in each case, as provided in Section 3.05, then either (A) such Global Security shall be so surrendered for exchange or cancellation, as provided in this Article III or
(B) the principal amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or canceled, or equal to the principal amount of such other Security to be so exchanged for a beneficial interest therein, as
the case may be, by means of an appropriate adjustment made on the records of the Trustee, as Security Registrar, whereupon the Trustee, in accordance with the Applicable Procedures, shall instruct the Depositary or its authorized representative to
make a corresponding adjustment to its records. Upon any such surrender or adjustment of a Global Security, the Trustee shall, subject to Section 3.05(c) and as otherwise provided in this Article III, authenticate and deliver any Securities issuable
in exchange for such Global Security (or any portion thereof) to or upon the order of, and registered in such names as may be directed by, the Depositary or its authorized representative. Upon the request of the Trustee in connection with the
occurrence of any of the events specified in 

  

 -50- 

 
the preceding paragraph, the Company shall promptly make available to the Trustee a reasonable supply of Securities that are not in the form of Global
Securities. The Trustee shall be entitled to rely upon any order, direction or request of the Depositary or its authorized representative which is given or made pursuant to this Article III if such order, direction or request is given or made in
accordance with the Applicable Procedures. 
  
 (iv) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Article III or otherwise, shall be authenticated and
delivered in the form of, and shall be, a registered Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof, in which case such Security shall be
authenticated and delivered in definitive, fully registered form, without interest coupons. 
  
 (v) The Depositary or its nominee, as registered owner of a Global Security, shall be the Holder of such Global Security for all purposes
under the Indenture and the Securities, and owners of beneficial interests in a Global Security shall hold such interests pursuant to the Applicable Procedures. Accordingly, any such owner’s beneficial interest in a Global Security will be
shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or its nominee or its Agent Members and such owners of beneficial interests in a Global Security will not be considered the owners
or holders thereof. 
  
 (b) Non-global
Securities. Securities issued upon the events described in Section 3.12(a)(ii) shall be in definitive, fully registered form, without interest coupons, and shall bear the Restricted Securities Legend if and as required by this Indenture.

  
 ARTICLE IV

Trustee as trust funds in trust for the purpose an amount sufficient to pay and discharge the entire Indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal (and premium, if any) and interest on the
Securities to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be, together with irrevocable instructions from the Company directing the Trustee to

 SECTION 4.02. Application of Trust Money. Subject to the provisions of the last paragraph of Section 10.03, all money
deposited with the Trustee pursuant to Section 4.01 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee. Money so held in trust is not
subject to Article XIV.

 SECTION 5.02. Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than those covered by clause (8) or (9) of Section 5.01 with respect to the Company) shall occur and be
continuing, the Trustee, by notice to the Company and the administrative agent under the Credit Agreement, or the Holders of at least 25% in aggregate principal amount of the Securities then Outstanding, by notice to the Trustee, the Company and the
administrative agent under the Credit Agreement, may declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all of the Outstanding Securities due and payable immediately, upon which declaration, all amounts payable in
respect of the Securities shall be due and payable as of the date which is five Business Days after the giving of such notice to the administrative agent under the Credit Agreement. If an Event of Default specified in clause (8) or (9) of Section
5.01 with respect to the Company occurs and is continuing, then the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Outstanding Securities 

  

 -54-

 After a declaration of acceleration under this Indenture, but
before a judgment or decree for payment of the money due has been obtained by the Trustee, the Holders of a majority in aggregate principal amount of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind such
declaration if

the Securities which has become due otherwise than by such declaration of acceleration; 
  
 (2) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and 
  
 (3) all Events of Default, other than the non-payment of
principal of, premium, if any, and interest on the Securities that has become due solely by such declaration of acceleration, have been cured or waived. 
  
 No such rescission shall affect any subsequent default or impair any right consequent thereto. 
  
 SECTION 5.03. Collection of Indebtedness and Suits for Enforcement by
Trustee. The Company and Holdings covenant that if 
  
 (i) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or 
  
 (ii) default is made in the payment of the principal of (or premium, if any, on) any Security on the due
date for payment thereof, including, with respect to any Security required to have been purchased pursuant to a Fundamental Change Offer made by the Company, at the Fundamental Change Purchase Date thereof, the Company or Holdings will, upon demand
of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium, if any) and interest, and, to the extent that payment of such interest shall be
legally enforceable, interest on any overdue principal (and premium, if any) and on any 

  

 -55- 

 
overdue interest, at the rate provided by the Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
  
 In addition to the rights and powers set forth in Section 317(a) of the Trust Indenture Act, the Trustee shall be entitled to file such other papers or
documents as may be necessary or advisable in order to have the claims of the Trustee and of the Holders of the Securities allowed in any judicial proceeding relative to the Company, Holdings or any other obligor upon the Securities, its creditors,
or its property, and to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute the same after the deduction of its charges and expenses; and any receiver, assignee or trustee in bankruptcy or
reorganization is hereby authorized by each of the Holders to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for
compensation and expenses, including counsel fees incurred by it up to the date of such distribution. 
  
 If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders
by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy. 
  
 SECTION
5.04. Trustee May File Proofs of Claim. In case of any judicial proceeding relative to the Company, Holdings (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by
intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized
to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.07. 
  
 No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee. 
  
 SECTION 5.05. Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this
Indenture or the Securities may be prosecuted and 

  

 -56- 

 
enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding
instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, distributions and advances of the Trustee, its
agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 
  
 SECTION 5.06. Application of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order,
at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and
upon surrender thereof if fully paid: 
  
 FIRST:
To the payment of all amounts due the Trustee under Section 6.07; 
  
 SECOND: To holders of Senior Indebtedness of the Company and, if such money or property has been collected from Holdings, to holders of Senior Indebtedness of Holdings, in each case to the extent required by Articles
XIII and XIV. 
  
 THIRD: To the payment of the
amounts then due and unpaid for principal of (and premium, if any) and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the
amounts due and payable on such Securities for principal (and premium, if any) and interest, respectively; 
  
 FOURTH: To the payment of any and all other amounts due under the Indenture, the Securities or the Guarantee; and 
  
 FIFTH: To the Company (or such other Person as a court of
competent jurisdiction may direct). 
  
 SECTION 5.07.
Limitation on Suits. Subject to Section 5.08, no Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless 
  
 (i) such Holder has
previously given written notice to the Trustee of a continuing Event of Default; 
  
 (ii) the Holders of not less than 25% in principal amount of the Outstanding Securities shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
  
 (iii) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to the Trustee against the costs, expenses and
liabilities to be incurred in compliance with such request; 
  
 (iv) the Trustee for 45 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and 
  

 -57- 

 (v) no direction inconsistent with such written request has been given to the Trustee
during such 45-day period by the Holders of a majority in principal amount of the Outstanding Securities; it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any
provision of this 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 Holders or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders. 
  
 SECTION 5.08. Unconditional Right of Holders to Receive Principal, Premium and Interest, and to Convert. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and
unconditional, to receive payment of the principal of (and premium, if any) and (subject to Section 3.07) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, repurchase or purchase
on the Redemption Date, Fundamental Change Purchase Date or Purchase Date, as the case may be), and to convert such Security in accordance with Article XV, and to institute suit for the enforcement of any such payment or right to convert, and such
rights shall not be impaired without the consent of such Holder. 
  
 SECTION 5.09. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason,
or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, Holdings, the Trustee and the Holders shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted, subject to the determination in such proceeding. 
  
 SECTION 5.10. Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
  
 SECTION 5.11. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security to
exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the
Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
  

 -58- 

 SECTION 5.12. Control by Holders. The Holders of a majority in principal amount of the Outstanding
Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, provided that; 
  
 (i) such direction shall not be in conflict with any rule of
law or with this Indenture, and 
  
 (ii) the
Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 
  
 SECTION 5.13. Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Securities may on behalf of
the Holders of all the Securities waive any past default hereunder and its consequences, except a default 
  
 (i) in the payment of the principal of (or premium, if any) or interest on any Security (including any Security which is required to have
been purchased pursuant to a Fundamental Change Offer which has been made by the Company), or 
  
 (ii) in respect of a covenant or provision hereof which under Article IX cannot be modified or amended without the consent of the Holder
of each Outstanding Security 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. 
  
 SECTION 5.14. Undertaking for Costs. In any
suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay
the costs of such suit (including reasonable counsel fees and expenses), and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided, that neither this Section nor the
Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company or Holdings, in any suit instituted by the Trustee, in any suit instituted by any Holder or
group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities, or in any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest on any
Security on or after the Stated Maturity expressed in such Security (or, in the case of redemption, on or after the Redemption Date or, in the case of a Fundamental Change Offer made by the Company and required to be accepted as to such Security, on
the applicable Fundamental Change Purchase Date, as the case may be). 
  
 SECTION 5.15. Waiver of Stay or Extension Laws. Each of the Company and Holdings covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect 

  

 -59- 

 
the covenants or the performance of this Indenture; and each of the Company and Holdings (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been
enacted. 
  
 ARTICLE VI

 SECTION 6.01. Certain Duties and Responsibilities. (a) Except during
the continuance of an Event of Default,

the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
  
 (ii) in the absence of bad faith on its part, the Trustee
may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such
certificates or opinions which by the provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture
but need not verify the contents thereof. 
  
 (b)
In case an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent Person would exercise or
use under the circumstances in the conduct of such Person’s own affairs. 
  
 (c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent misconduct, except that no provision of this Indenture shall require the Trustee to expend or risk its
own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers under this Indenture, unless the Trustee has received security and indemnity satisfactory to it
against any loss, liability or expense. The Trustee shall not be liable for any error of judgment unless it is proved that the Trustee was negligent in the performance of its duties hereunder.

 (f) the Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee,
in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled (subject to reasonable

attorney; 
  

 -61- 

 (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties

the Trustee or any Authenticating Agent assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. The Trustee shall not be accountable for the use
or application by the Company of Securities or the proceeds thereof.

forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 6.11, become the successor Trustee and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so
appointed by the Company or the Holders and accepted appointment in accordance with the applicable requirements of Section 6.11, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

hereunder. 
  
 (h) No Trustee under this
Indenture shall be liable for any action or omission of any successor Trustee. 
  
 SECTION 6.11. Acceptance of Appointment by Successor. Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the
retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Company shall execute any and all instruments for
more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts. 
  
 No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this
Article. 
  
 SECTION 6.12. Merger, Conversion, Consolidation or
Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided, however, such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. 
  
 SECTION 6.13. Preferential Collection of Claims Against the Company or the
Guarantor. If and when the Trustee shall be or become a creditor of the Company or Holdings (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims

 SECTION 6.14. Appointment of Authenticating Agent. The Trustee may appoint an Authenticating Agent
or Agents which shall be authorized to act on behalf of the Trustee to authenticate Securities issued upon original issue and upon exchange, registration of transfer or partial redemption or partial purchase or pursuant to Section 3.06, and
Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and
delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by federal or state authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating
Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such
Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. 
  
 Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be
an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. 
  
 An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or
upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company
and shall give notice of such appointment in the manner provided in Section 1.06, to all Holders as their names and addresses appear in the Security Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall
become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this
Section. 
  
 The Company agrees to pay to each Authenticating
Agent from time to time reasonable compensation for its services under this Section.

determine, new Securities or Guarantees so modified as to conform, in the opinion of the Trustee, Holdings and the Company, to any such supplemental indenture may be prepared and executed by the Company or Holdings and authenticated and delivered by
the Trustee in exchange for Outstanding Securities.

 SECTION 9.07. No Liability for Certain Persons. No director, officer, employee, or stockholder of
Holdings or the Company, as such, shall have any liability for any obligations of the Company or Holdings under the Securities, the Guarantee or this Indenture based on or by reason of such obligations or their creation. Each Holder by accepting a
Security waives and releases all such liability. The foregoing waiver and release are an integral part of the consideration for the issuance of the Securities and the Guarantee.

 SECTION 10.01. Payment of Principal, Premium and Interest. The Company shall duly and punctually pay the principal of (and premium, if any) and
interest on the Securities in accordance with the terms of the Securities and this Indenture. The Company will deposit or cause to be deposited with the Trustee or its nominee, no later than the opening of business on the date of the Stated Maturity
of any Security or no later than the opening of business on the due date for any installment of interest, all payments so due, which payments shall be in immediately available funds on the date of such Stated Maturity or due date as the case may be.

  
 SECTION 10.02. Maintenance of Office or Agency. The
Company shall maintain in the Borough of Manhattan, The City of New York, an office or agency where Securities may be presented or surrendered for payment or for conversion, where Securities may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company or Holdings in respect of the Securities, the Guarantee and this Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in
the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be
made or served at a Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. In the event any such notice or demands are so made or served on
the Trustee, the Trustee shall promptly forward copies thereof to the Company. 
  
 The Company may also from time to time designate one or more other offices or agencies (in or outside the Borough of Manhattan, The City of New York) where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of
Manhattan, The City of New York, for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
  
 The Company hereby initially designates the Trustee as Paying Agent, Security
Registrar and Conversion Agent, and the Corporate Trust Office of the Trustee in the Borough of Manhattan, The City of New York, located at 101 Barclay Street, Floor 8 West, New York, New York 10286, Attention: Corporate Trust Administration, as one
such office or agency of the Company for each of the aforesaid purposes. 
  

 -72- 

 SECTION 10.03. Money for Security Payments to be Held in Trust. If the Company shall at any time
act as its own Paying Agent, it will, on or before each due date of the principal of (and premium, if any) or interest on any of the Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the
principal (and premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 
  
 Whenever the Company shall have one or more Paying Agents, the Company will,
prior to 11:00 a.m., New York City time, on each due date of the principal of (and premium, if any) or interest on any Securities, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due,
such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 
  
 The Company shall cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: (i) comply with the provisions of the Trust Indenture Act applicable to it as Paying Agent and (ii) during the continuance
of any default by the Company (or any other obligor upon the Securities) in the making of any payment in respect of the Securities, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent as
such. 
  
 The Company may at any time, for the purpose of
obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by such Paying Agent; and, upon such payment by any Paying Agent (other than the Company) to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

  
 Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest on any Security and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The City of New York, notice that
such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and material franchises; provided, however, that the Company shall not be required to preserve any such right or
franchise if the Board of Directors of the Company in good faith shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material
respect to the Holders. 
  
 SECTION 10.05. Payment of Taxes and
Other Claims. The Company shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the Company or any of its Significant

Company or any of its Significant Subsidiaries; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or
validity is being contested in good faith by appropriate proceedings. 
  
 SECTION 10.06. Fundamental Change. (a) Upon the occurrence of a Fundamental Change, the Company shall make an offer to purchase (a “Fundamental Change Offer”) on a Business Day not more than 60 nor less than 30 days
following the occurrence of the Fundamental Change (the “Fundamental Change Purchase Date”), all of the then Outstanding Securities tendered at a purchase price in cash (the “Fundamental Change Purchase Price”)
equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, thereon to the Fundamental Change Purchase Date. The Company shall be required to purchase all Securities tendered pursuant to the Fundamental Change Offer and

 (c) The Company shall not be required to make a Fundamental
Change Offer upon a Fundamental Change if a third party makes the Fundamental Change Offer in the manner, at the times and otherwise in compliance with the requirements applicable to a

Fundamental Change Offer made by the Company and purchases all Securities validly tendered and not withdrawn under such Fundamental Change Offer. 

 
 (d) The Company shall comply with Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder, to the extent such laws or regulations are applicable, in the event that a Fundamental Change occurs and the Company is required to purchase Securities as described above.

  
 (e) Upon the occurrence of a Fundamental
Change, the Company shall not repurchase any Subordinated Indebtedness of the Company pursuant to an offer to purchase or otherwise until (1) the requirements of this Section 10.06 have been satisfied or (2) the Company shall have obtained the
requisite consent under this Indenture to permit the repurchase of such Subordinated Indebtedness. 
  
 (f) In order to effect a Fundamental Change Offer, the Company shall, not later than 30 days following the date of the occurrence of a
Fundamental Change (the “Fundamental Change Date”), send or cause to be sent by first-class mail, postage prepaid, to each Holder of Securities at its address appearing in the register for the Securities on the date of the
Fundamental Change Offer, a notice of such Fundamental Change Offer (the “Fundamental Change Offer Notice”), which notice shall govern the terms of such Fundamental Change Offer. Unless otherwise required by applicable law, the
Fundamental Change Offer Notice shall specify an expiration date of the Fundamental Change Offer which shall be not less than 20 Business Days following the date of such Fundamental Change Offer (or such later date as may be necessary for the
Company to comply with the Exchange Act), and shall set forth a Fundamental Change Purchase Date determined in accordance with this Section 10.06. The Company shall notify the Trustee at least 15 Business Days (or such shorter period as is

 Redemption of Securities 
  
 SECTION 11.01. Right of Redemption. The Securities may be redeemed at the election of the Company, in the amounts, at the times, at the Redemption
Prices (together with any applicable accrued and unpaid interest to the Redemption Date), and subject to the conditions specified in the form of Security and hereinafter set forth. 
  
 SECTION 11.02. Applicability of Article. Redemption of Securities at the election of the Company, as permitted by
this Indenture and the provisions of the Securities, shall be made in accordance with such provisions and this Article. 
  
 SECTION 11.03. Election to Redeem; Notice to Trustee. The election of the Company to redeem any Securities pursuant to Section 11.01 shall be
evidenced by a Board Resolution. In the event of any redemption at the election of the Company pursuant to Section 11.01, the Company shall notify the Trustee, in case of a redemption of less than all the Securities, at least 60 days, and in the
case of a redemption of all the Securities, at least 40 days, prior to the Redemption Date fixed by the Company (in each case, unless a shorter notice shall be satisfactory to the Trustee) of such Redemption Date and of the principal amount of
Securities to be redeemed. 
  
 SECTION 11.04. Selection by
Trustee of Securities to Be Redeemed. In the event that less than all of the Securities are to be redeemed at any time, selection of such Securities for 

  

 -77- 

 
redemption will be made by the Trustee on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate (subject to the rules of
the Depositary); provided, however, that Securities shall only be redeemable in amounts of $1,000 or an integral multiple of $1,000. 
  
 If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities that have been converted during a selection of Securities to be redeemed may be treated by the
Trustee as Outstanding for the purpose of such selection. The Trustee shall promptly notify the Company and each Security Registrar in writing of the Securities selected for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed. 
  
 For
all purposes of this Indenture and of the Securities, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed. 
  
 SECTION 11.05. Notice of Redemption. Notice of redemption shall be given by first class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of
Securities to be redeemed, at his address appearing in the Security Register. 
  
 All notices of redemption shall identify the Securities to be redeemed (including, if used, CUSIP or CINS numbers) and shall state: 
  
 (i) the Redemption Date; 
  
 (ii) the Redemption Price; 
  
 (iii) if less than all the Outstanding Securities are to be redeemed, the identification (and, in the case
of partial redemption, the principal amounts) of the particular Securities to be redeemed; 
  
 (iv) that on the Redemption Date the Redemption Price and accrued interest to, but excluding, the Redemption Date will become due and
payable upon each such Security to be redeemed and that interest thereon will cease to accrue on and after such Redemption Date; 
  
 (v) the place or places where such Securities are to be surrendered for payment of the Redemption Price and accrued interest to, but
excluding, the Redemption Date; and 
  
 (vi) the
Conversion Rate, the date on which the right to convert the Securities to be redeemed will terminate and the places where such Securities may be surrendered for conversion. 
  

 -78- 

 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the
Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company and shall be irrevocable. 
  
 SECTION 11.06. Deposit of Redemption Price. Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.03) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) any
applicable accrued interest on, all the Securities which are to be redeemed on that date, other than any Securities called for redemption on that date which have been converted prior to the date of deposit. 
  
 SECTION 11.07. Securities Payable on Redemption Date. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the
payment of the Redemption Price and any applicable accrued interest or the Paying Agent is prohibited from making such payment pursuant to Article XIV) interest shall cease to accrue on such Securities or portions thereof. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with any applicable accrued and unpaid interest to the Redemption Date; provided, however, that
installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more predecessor securities, registered as such at the close of business on the relevant record dates
according to their terms and the provisions of Section 3.07. 
  
 If any Security called for redemption in accordance with the election of the Company made pursuant to Section 11.01 shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear
interest from the Redemption Date at the rate provided by the Security, and such Security shall remain convertible until the Redemption Price of such Security (or portions thereof, as the case may be) shall have been paid or duly provided for.

  
 SECTION 11.08. Securities Redeemed in Part. Any
Security which is to be redeemed only in part shall be surrendered at an office or agency of the Company designated for that purpose pursuant to Section 10.02 (with, if the Company or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder
of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, in aggregate principal amount at Stated Maturity equal to and in exchange for the unredeemed portion of the principal
amount at Stated Maturity of the Security so surrendered.

delivery of such Security to the Paying Agent prior to, on or after the applicable Purchase Date (together with all necessary endorsements) (at the offices of the Paying Agent in the case of certificated Securities or otherwise by book-entry
transfer) is a condition to receipt by the Holder of the Purchase Price therefor; provided, however, that such Purchase Price shall be so paid pursuant to this Section 12.01 only if the Security so delivered to the Paying Agent shall conform
in all respects to the description thereof in the related Purchase Notice. 
  
 The Paying Agent shall promptly notify the Company of the receipt by it of a Purchase Notice. 
  
 Any purchase by the Company contemplated pursuant to the provisions of this Section 12.01 shall be consummated by the delivery of the consideration from
the Company to the Paying Agent, to be received by the Holder promptly following the later of the applicable Purchase Date and the time of delivery of the Security. 
  
 If the Paying Agent holds money or securities sufficient to pay the Purchase Price of the Securities on the Business Day
following the applicable Purchase Date in accordance with the terms of this Indenture, then, immediately after such Purchase Date, the Securities will cease to be Outstanding whether or not the Securities have been delivered to the Paying Agent;
provided that the Paying Agent is not prohibited from paying such money to the Holders pursuant to Article XIV hereof. Thereafter, all other rights of the Holders shall terminate, other than the right to receive the Purchase Price upon
delivery of the Securities. 
  

 -80- 

 Provisions of this Indenture that apply to the purchase of all of a Security also apply to the purchase
of a portion of a Security. 
  
 SECTION 12.02. Notice of
Purchase. The Company is required to give notice (the “Notice of Purchase”) to the Holders on a date that is no less than 20 Business Days prior to the applicable Purchase Date. The Notice of Purchase shall be delivered to all
Holders at their respective addresses shown in the Securities Register and to beneficial owners as required by law, and shall include the following information: 
  
 (a) the name and address of the Paying Agent;

 SECTION 12.03. Notice of Withdrawal. Notwithstanding
anything herein to the contrary, any Holder delivering to the Paying Agent the Purchase Notice contemplated by this Article XII shall have the right to withdraw such Purchase Notice at any time prior to the close of business on the applicable

 Guarantee 
  
 SECTION 13.01. Guarantee. Holdings hereby unconditionally and
irrevocably guarantees, on a senior subordinated basis, to each Holder and to the Trustee and its successors and assigns (a) the full and prompt payment (within applicable grace periods) of principal of and interest on the Securities when due,
whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Indenture and the Securities and (b) the full and prompt performance within applicable grace periods of all other
obligations of the Company under this Indenture and the Securities (all the foregoing being hereinafter collectively called the “Guarantee Obligations”). Holdings further agrees that the Guarantee Obligations may be extended or
renewed, in whole or in part, without notice or further assent from Holdings, and that Holdings will remain bound under this Article XIII notwithstanding any extension or renewal of any Guarantee Obligation. 
  
 Holdings waives presentation to, demand of payment from and protest to the
Company of any of the Guarantee Obligations and also waives notice of protest for nonpayment. Holdings waives notice of any default under the Securities or the Guarantee Obligations. The obligations of Holdings hereunder shall not be affected by (a)
the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Securities or any other agreement or otherwise; (b) any extension or renewal
of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Guarantee
Obligations or any of them; (e) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Guarantee Obligations; or (f) any change in the ownership of Holdings. 
  
 Holdings further agrees that its Guarantee herein constitutes a guarantee of
payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guarantee Obligations. 
  
 To the fullest extent permitted by law, the obligations of Holdings hereunder
shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or
termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guarantee Obligations or otherwise. Without limiting the generality of the foregoing, to the fullest extent permitted by law, the obligations of Holdings
herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this 

  

 -82- 

 
Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, wilful or otherwise, in the
performance of the Guarantee Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of Holdings or would otherwise operate as a discharge of such
guarantor as a matter of law or equity. 
  
 Holdings further
agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guarantee Obligation is rescinded or must otherwise be restored by
any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise. 
  
 In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against Holdings by virtue hereof, upon the failure of the Company to pay the principal
of or interest on any Guarantee Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption, by repurchase or otherwise (within applicable grace periods), or to perform or comply with any other Guarantee
Obligation (within applicable grace periods), Holdings hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (i) the
unpaid principal amount of such Guarantee Obligations, (ii) accrued and unpaid interest on such Guarantee Obligations (but only to the extent not prohibited by law) and (iii) all other monetary Guarantee Obligations of the Company to the Holders and
the Trustee. 
  
 Holdings agrees that it shall not be entitled to
any right of subrogation in relation to the Holders in respect of any Guarantee Obligations Guaranteed hereby until payment in full of all Guarantee Obligations. Holdings further agrees that, as between Holdings, on the one hand, and the Holders and
the Trustee, on the other hand, (x) the maturity of the Guarantee Obligations Guaranteed hereby may be accelerated as provided in Article V for the purposes of its Guarantee herein, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the Guarantee Obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such Guarantee Obligations as provided in Article V, such Guarantee Obligations (whether or not due
and payable) shall forthwith become due and payable by Holdings for the purposes of this Section. 
  
 Holdings also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder
in enforcing any rights under this Section. 
  
 SECTION 13.02.
[Intentionally Omitted]. 
  
 SECTION 13.03. Execution
and Delivery of Guarantee. The Guarantee to be endorsed on the Securities shall be in the form set forth in Exhibit C. Holdings hereby agrees to execute its Guarantee in such form, to be endorsed on each Security authenticated and delivered by
the Trustee. 
  
 The Guarantee shall be executed on behalf of
Holdings by any one of Holdings’ Chairman of the Board, Vice Chairman of the Board, President, Chief Financial Officer or Vice 

  

 -83- 

 
Presidents and any authorized signatories for Holdings that are not corporations. The signature of any or all of these officers on the Guarantee may be
manual or facsimile. 
  
 A Guarantee bearing the manual or
facsimile signatures of individuals who were at any time the proper officers of Holdings shall bind Holdings, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of the
Security on which such Guarantee is endorsed or did not hold such offices at the date of such Guarantee. 
  
 The Guarantee shall be registered, transferred, exchanged and cancelled, and shall be held in definitive or global form, in the same manner and together
with, the Security to which it relates, in accordance with Article III. 
  
 The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee endorsed thereon on behalf of Holdings. Holdings hereby agrees that its Guarantee set forth in Section
13.01 shall remain in full force and effect notwithstanding any failure to endorse a Guarantee on any Security. 
  
 SECTION 13.04. Successors and Assigns. This Article XIII shall be binding upon Holdings and its successors and assigns and shall inure to the
benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities
shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture. 
  
 SECTION 13.05. No Waiver, etc. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or
privilege under this Article XIII shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article XIII at law, in equity, by statute or otherwise. 
  
 SECTION 13.06. Modification, etc. No modification, amendment or waiver
of any provision of this Article, nor the consent to any departure by Holdings therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. No notice to or demand on Holdings in any case shall entitle Holdings or any other guarantor to any other or further notice or demand in the same, similar or other circumstances. 
  
 SECTION 13.07. Subordination of Guarantee. The obligations of Holdings
pursuant to its Guarantee and this Article XIII shall be (a) junior and subordinated in right of payment to the prior payment in full in cash of all Senior Indebtedness of Holdings and (b) senior in right of payment to all existing and future
Subordinated Indebtedness of Holdings, in each case on the same basis as the Securities and the obligations of the Company hereunder are junior and subordinated to all Senior Indebtedness of the Company and senior in right of payment to all
Subordinated Indebtedness of the Company. For the purposes of this 

  

 -84- 

 
Section 13.07, Article XIV shall apply to the obligations of Holdings under its Guarantee, this Article XIII and the other provisions of this Indenture as if
references therein to the Company, the Securities, Senior Indebtedness of the Company, Subordinated Indebtedness of the Company and Designated Senior Indebtedness of the Company were references to Holdings, Holdings’ Guarantee, Senior
Indebtedness of Holdings, Subordinated Indebtedness of Holdings and Designated Senior Indebtedness of Holdings, respectively. 
  
 ARTICLE XIV 
  
 Subordination 
  
 SECTION 14.01. Securities Subordinate to Senior Indebtedness and Senior to Subordinated Indebtedness. The Company covenants and agrees, and each Holder of a Security, by his acceptance thereof, likewise
covenants and agrees that, to the extent and in the manner hereinafter set forth in this Article XIV, the Indebtedness evidenced by the Securities is hereby expressly made subordinate in right of payment to the prior payment in full in cash of all
Senior Indebtedness and senior in right of payment to all existing and future Subordinated Indebtedness of the Company. 
  
 SECTION 14.02. Payment Over of Proceeds Upon Dissolution, Etc. In the event of any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relating to the Company or its assets, or any liquidation, dissolution or other winding-up of the Company, whether voluntary or involuntary, or
any assignment for the benefit of creditors or other marshalling of assets or liabilities of the Company, all Senior Indebtedness (including, in the case of Designated Senior Indebtedness, any interest accruing subsequent to the filing of a petition
for bankruptcy (regardless of whether such interest is an allowed claim in the bankruptcy proceeding)) must be paid in full in cash before any payment (other than payments in the form of Qualified Equity Interests or other securities the payment of
which is subordinated, at least to the same extent as the Securities, to the payment of all Senior Indebtedness which may at the time be outstanding) is made on account of the principal of, premium, if any, or interest on the Securities. 

 
 SECTION 14.03. No Payment When Designated Senior Indebtedness is in
Default. During the continuance of any default in the payment of principal, or premium, if any, or interest on any Senior Indebtedness, when the same becomes due, and after receipt by the Trustee and the Company from representatives of holders
of such Senior Indebtedness of written notice of such default, no direct or indirect payment by or on behalf of the Company of any kind or character (other than Qualified Equity Interests or other securities the payment of which is subordinated, at
least to the same extent as the Securities, to the payment of all Senior Indebtedness which may at the time be outstanding) may be made on account of the principal of, premium, if any, or interest on, or the purchase, redemption or other acquisition
of, the Securities unless and until such default has been cured or waived or has ceased to exist or such Senior Indebtedness shall have been discharged or paid in full in cash, after which the Company shall resume making any and all required
payments in respect of the Securities, including any missed payments. 
  

 -85- 

 In addition, during the continuance of any other default with respect to any Designated Senior
Indebtedness that permits, or would permit with the passage of time or the giving of notice or both, the maturity thereof to be accelerated (a “Non-payment Default”) and upon the earlier to occur of (a) receipt by the Trustee and
the Company from the representatives of holders of such Designated Senior Indebtedness of a written notice of such Non-payment Default or (b) if such Non-payment Default results from the acceleration of the maturity of the Securities, the date of
such acceleration, no payment of any kind or character (excluding Qualified Equity Interests or subordinated securities) may be made by the Company on account of the principal of, premium, if any, or interest on, or the purchase, redemption, or
other acquisition of, the Securities for the period specified below (the “Payment Blockage Period”). 
  
 The Payment Blockage Period shall commence upon the receipt of notice of a Non-payment Default by the Trustee and the Company from the representatives of
holders of Designated Senior Indebtedness or the date of the acceleration referred to in clause (b) of the preceding paragraph, as the case may be, and shall end on the earliest to occur of the following events: (i) 179 days have elapsed since the
receipt of such notice or the date of the acceleration referred to in clause (b) of the preceding paragraph (provided the maturity of such Designated Senior Indebtedness shall not theretofore have been accelerated), (ii) such default is cured
or waived or ceases to exist or such Designated Senior Indebtedness is discharged or paid in full in cash, or (iii) such Payment Blockage Period shall have been terminated by written notice to the Company or the Trustee from the representatives of
holders of Designated Senior Indebtedness initiating such Payment Blockage Period, after which the Company shall promptly resume making any and all required payments in respect of the Securities, including any missed payments. Only one Payment
Blockage Period with respect to the Securities may be commenced within any 360 consecutive day period. No Non-payment Default with respect to Designated Senior Indebtedness that existed or was continuing on the date of the commencement of any
Payment Blockage Period shall be, or can be, made the basis for the commencement of a second Payment Blockage Period, whether or not within a period of 360 consecutive days, unless such default has been cured or waived for a period of not less than
90 consecutive days. In no event shall a Payment Blockage Period extend beyond 179 days from the date of the receipt by the Trustee of the notice or the date of the acceleration initiating such Payment Blockage Period and there must be a 180
consecutive day period in any 360 day period during which no Payment Blockage Period is in effect. 
  
 SECTION 14.04. Subrogation to Rights of Holders of Senior Indebtedness. Subject to the payment in full in cash of all Senior Indebtedness, the
Holders of the Securities shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article XIV to the rights of the holders of such Senior Indebtedness to
receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness until the principal of, premium, if any, and interest on the Securities shall be paid in full. For purposes of such subrogation, no payments or
distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the Holders of the Securities or the Trustee would be entitled except for the provisions of this Article XIV, and no payments over pursuant to the
provisions of this Article XIV to the holders of Senior Indebtedness by Holders of the Securities or the Trustee, shall, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Securities, be deemed to be
a payment or distribution by the Company to or on account of the Senior Indebtedness. 
  

 -86- 

 SECTION 14.05. Provisions Solely to Define Relative Rights. The provisions of this Article XIV are
and are intended solely for the purpose of defining the relative rights of the Holders of the Securities on the one hand and the holders of Senior Indebtedness on the other hand. Nothing contained in this Article XIV or elsewhere in this Indenture
or in the Securities is intended to or shall (a) impair, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional, to pay to
the Holders of the Securities the principal of, premium, if any and interest on the Securities as and when the same shall become due and payable in accordance with their terms; (b) affect the relative rights against the Company of the Holders of the
Securities and creditors of the Company other than the holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Securities from exercising all remedies otherwise permitted by applicable law upon default under this Indenture,
subject to the rights, if any, under this Article XIV of the holders of Senior Indebtedness to receive cash, property and securities otherwise payable or deliverable to the Trustee or such Holder. 
  
 SECTION 14.06. Trustee to Effectuate Subordination. Each Holder of a
Security by its acceptance thereof authorizes and directs the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article XIV and appoints the Trustee its attorney-in-fact for
any and all such purposes. 
  
 SECTION 14.07. No Waiver of
Subordination Provisions. No right of any present or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the
Company or by any act or failure to act, in good faith, by any such holder, or by any non-compliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with. 
  
 Without in any way limiting the
generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Securities, without incurring responsibility to the Holders of
the Securities and without impairing or releasing the subordination provided in this Article XIV or the obligations hereunder of the Holders of the Securities to the holders of Senior Indebtedness, do any one or more of the following: (i) change the
manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Indebtedness, or otherwise amend or supplement in any manner Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior
Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any Person liable in any manner for the collection of Senior Indebtedness; and
(iv) exercise or refrain from exercising any rights against the Company and any other Person. 
  
 SECTION 14.08. Notice to Trustee. The Company shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit the making of any payment to or by the Trustee in respect of
the Securities. Notwithstanding the provisions of this Article XIV or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the
Trustee in respect of the Securities, unless and until the Trustee shall have received written notice thereof from the Company or a holder of Senior Indebtedness or from any trustee 

  

 -87- 

 
therefor; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Section 6.01, shall be entitled in all respects to
assume that no such facts exist; provided, however, that if the Trustee shall not have received at its Corporate Trust Office the notice provided for in this Section at least three Business Days prior to the date upon which by the terms
hereof any money may become payable for any purpose (including, without limitation, the payment in cash of the principal of, premium, if any or interest on any Security), then, anything herein contained to the contrary notwithstanding, the Trustee
shall have full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it within three Business Days prior to
such date. 
  
 SECTION 14.09. Reliance on Judicial Order or
Certificate of Liquidating Agent. Upon any payment or distribution of assets of the Company referred to in this Article XIV, the Trustee, subject to the provisions of Section 6.01, and the Holders of the Securities shall be entitled to rely upon
any order or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of Senior Indebtedness and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article XIV. 
  
 SECTION 14.10.
Trustee Not Fiduciary for Holders of Senior Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders if it shall in good faith mistakenly pay
over or distribute to Holders of Securities or to the Company or to any other Person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article XIV or otherwise, except in the case of gross
negligence or wilful misconduct on the part of the Trustee. 
  
 With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are specifically set forth in this Article and no implied covenants or obligations with respect
to holders of Senior Indebtedness shall be read into this Indenture against the Trustee. 
  
 SECTION 14.11. Rights of Trustee as Holder of Senior Indebtedness; Preservation of Trustee’s Rights. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article XIV
with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. 
  
 Nothing in this Article XIV shall apply to claims of, or payments to, the
Trustee or its agent or counsel under or pursuant to Section 6.07. 
  
 SECTION 14.12. Article Applicable to Paying Agents. In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then 

  

 -88- 

 
acting hereunder, the term “Trustee” as used in this Article XIV shall in such case (unless the context otherwise requires) be construed as
extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article XIV in addition to or in place of the Trustee; provided, however, that Section 14.11
shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. 
  
 ARTICLE XV 
  
 Conversion of Securities 
  
 SECTION 15.01.
Conversion Privilege and Conversion Rate. (a) Subject to and upon compliance with the provisions of this Article XV, at the option of the Holder thereof, any Security that is an integral multiple of $1,000 may be converted into fully paid and
nonassessable shares (calculated as to each conversion to the nearest 1/100th of a share) of Common Stock at the Conversion Rate, determined as hereinafter provided, in effect at the time of conversion and subject to the adjustments described below,
as follows: 
  
 (1) if, on or prior to October
15, 2022, the Closing Price of the Common Stock for at least 20 Trading Days in the period of the 30 consecutive Trading Days ending on the last Trading Day of any fiscal quarter is more than 125% of the then current Conversion Price of the
Securities, then the Holder thereof will be entitled to convert such Security during the immediately following fiscal quarter; 
  
 (2) if, on any date after October 15, 2022, the Closing Price of the Common Stock is more than 125% of the then current Conversion Price
of the Securities, then the Holder thereof will be entitled to convert such Security at all times thereafter 
  
 (3) if the Company elects to call the Securities for redemption on or after October 20, 2010, then the Holder thereof will be entitled to
convert such Security (or the portion of the Security called for redemption, if less than all), until the close of business on the Trading Day prior to the Redemption Date; 
  
 (4) if Holdings distributes to all or substantially all holders of Common Stock rights, options or warrants
entitling them to purchase Common Stock at less than the Closing Price of the Common Stock on the last day preceding the declaration for such distribution, except with respect to any existing or future Rights Plan, then the Holder thereof will be
entitled to convert such Security in the period described below; 
  
 (5) if Holdings distributes to all or substantially all holders of Common Stock cash, assets, debt securities or capital stock, which distribution has a per share value as determined by the Board of Directors of
Holdings exceeding 5% of the Closing Price of the Common Stock on the last day preceding the declaration for such distribution, then the Holder thereof will be entitled to convert such Security in the period described below; or 
  
 (6) if the Company or Holdings becomes a party to a
consolidation, merger or sale of all or substantially all of its assets where such consolidation, merger or sale of all or 

  

 -89- 

 
substantially all assets constitutes a Fundamental Change or such an event occurs that would have been a Fundamental Change but for the exceptions (a) and
(b) to the definition of “Fundamental Change” set forth in the second paragraph of such definition, then the Holder thereof will be entitled to convert such Security in the period described below. 
  
 In the case of a distribution contemplated in clauses (4) and (5) of this
Section 15.01(a), the Company will notify Holders at least 20 days prior to the ex-dividend date for such distribution (the “Distribution Notice”). Once the Company has given the Distribution Notice, Holders may surrender their
Securities for conversion at any time until the earlier of the close of business on the last Business Day preceding the ex-dividend date or the Company’s announcement that such distribution will not take place. If in the future Holdings adopts
another Rights Plan, or if Holdings amends or issues additional Rights under its Rights Plan in existence on the Issue Date, Holders will not have any conversion right pursuant to clause (4) above or otherwise, solely as a result of the issuance of
Rights pursuant to any such Rights Plan. Notwithstanding the foregoing, in the event of a distribution contemplated in clauses (4) and (5) of this Section 15.01(a), Holders may not convert the Securities if the Holders may participate in such
distribution without converting their Securities. 
  
 In the event
of a consolidation, merger or sale of all or substantially all of the Company’s or Holdings’ assets as contemplated in clause (6) of this Section 15.01(a), the Company will notify Holders at least 20 days prior to the anticipated closing
date of such transaction (the “Merger Notice”). Once the Company has given the Merger Notice, the Holders may, in the event of such consolidation, merger or sale of all or substantially all of the Company’s or Holdings’
assets, as contemplated in clause (6) above, surrender Securities for conversion at any time from and after the date which is 15 days prior to the anticipated effective date of such transaction until the date which is 15 days after the actual
effective date of such transaction. 
  
 With respect to clause (1)
of this Section 15.01(a), the Conversion Agent will determine, on behalf of the Company, on the last Trading Day succeeding the first day of the fiscal quarter in which the Securities would be convertible, whether the Securities are convertible as
set forth in such clause (1) based upon the Closing Price of the Common Stock and the then current Conversion Price and, if so, will notify the Company. 
  
 (b) Subject to the further provisions of this Article XV, a Holder of a Security may also convert the principal amount of such Security (or any portion
thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) for the five Business Day period after any five consecutive Trading Day period in which the average of the Trading Prices for the Securities for such five Trading Day
period was less than 95% of the average Conversion Value for the Securities during such period; provided, however, that if on the Conversion Date, the Closing Price of shares of Common Stock is greater than the then current Conversion Price
of the Securities and less than or equal to 125% of the then current Conversion Price of the Securities, a Holder surrenders its Securities for conversion and the Securities are not otherwise convertible, then such Holder will receive, (i) at the
Company’s option for a Conversion Date on or before October 19, 2010, cash or Common Stock with a value equal to the principal amount of such Holder’s Securities on such Conversion Date or (ii) for a Conversion Date on or after October

  

 -90- 

 
20, 2010, cash equal to the principal amount of such Holder’s Securities on such Conversion Date and for such conversion the Company will not have the
option to pay in Common Stock. If the Company elects to pay the Holder in Common Stock, the Common Stock will be valued at 100% of the average Closing Price of Common Stock for the five Trading Days ending on the third Trading Day preceding the
Conversion Date. 
  
 The “Conversion Value” for
the Securities is equal to the product of (i) the Closing Price of the Common Stock on a given day and (ii) the then current Conversion Rate. 
  
 The “Trading Price” of the Securities on any Trading Day means the average of the secondary market bid quotations per Security obtained
by the Conversion Agent for $5,000,000 principal amount of the Securities at approximately 3:30 p.m., New York City time, on such Trading Day from an independent nationally recognized securities dealer the Company selects; provided that if
the Conversion Agent cannot reasonably obtain a bid for $5,000,000 principal amount of the Securities from a nationally recognized securities dealer or if in the Company’s reasonable judgment, the bid quotations are not indicative of the
secondary market value of the Securities, then the Trading Price of the Securities will be deemed to be equal to the product of the then current Conversion Rate and the Closing Price of Common Stock on such Trading Day. The Conversion Agent shall
have no obligation to determine the Trading Price of the Securities unless the Company has requested such determination; and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable evidence that
the Trading Price of the Securities is reasonably likely to be less than 95% of the Conversion Value; at which time, the Company shall instruct the Conversion Agent to determine the Trading Price of the Securities beginning on the next Trading Day
and on each successive Trading Day until the Trading Price is greater than or equal to 95% of the Conversion Value. 
  
 (c) The conversion right, subject to the conditions described in clauses (a) and (b) of this Section 15.01, shall commence on the Issue Date and expire at
the close of business on the Maturity Date, subject, in the case of conversion of any Global Security, to any Applicable Procedures. In case a Holder of a Security exercises his right to require the Company to repurchase a Security, such conversion
right in respect of the Security, or portion thereof so called, shall expire at the close of business on the second Trading Day immediately preceding the Fundamental Change Purchase Date unless the Company defaults in making the payment due upon
repurchase (subject as aforesaid to any Applicable Procedures with respect to any Global Security). 
  
 Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of a Security. 
  
 A Holder of Securities is not entitled to any rights of a holder of Common
Stock until such Holder has converted its Securities into Common Stock, and only to the extent such Securities are deemed to have been converted into Common Stock pursuant to this Article XV. 
  
 The rate at which shares of Common Stock shall be delivered upon conversion
(herein called the “Conversion Rate”) shall be initially 38.9520 shares of Common Stock for each $1,000 principal amount of Securities. The Conversion Rate shall be adjusted in certain instances as provided in this Article XV.

  

 -91- 

 SECTION 15.02. Exercise of Conversion Privilege. In order to exercise the conversion privilege,
the Holder of any Security to be converted shall surrender such Security, duly endorsed in blank, at any office or agency of the Company maintained for that purpose pursuant to this Indenture, accompanied by a duly signed and completed conversion
notice substantially in the form set forth in Section 2.02 hereof stating that the Holder elects to convert such Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted. 
  
 Each Security surrendered for conversion (in whole or in part) during the
Record Date Period shall (except in the case of any Security or portion thereof which has been called for redemption on a Redemption Date, is repurchasable on a Fundamental Change Purchase Date or purchasable on a Purchase Date, occurring, in any
such case, within such Record Date Period and, as a result, the right to convert such Security would otherwise terminate in such period if not exercised) be accompanied by payment in New York Clearing House funds or other funds acceptable to the
Company in an amount equal to the interest, if any, payable on such Interest Payment Date on the principal amount of such Security (or part thereof, as the case may be) being surrendered for conversion. The interest so payable on such Interest
Payment Date with respect to any Security (or portion thereof, if applicable) that is surrendered for conversion during the Record Date Period shall be paid to the Holder of such Security as of such Record Date in an amount equal to the interest
that would have been payable on such Security if such Security had been converted as of the close of business on such Interest Payment Date. Interest payable on any Interest Payment Date in respect of any Security surrendered for conversion on or
after such Interest Payment Date shall be paid to the Holder of such Security as of the Record Date next preceding such Interest Payment Date, notwithstanding the exercise of the right of conversion. 
  
 Except as provided in the preceding paragraph and subject to the last
paragraph of Section 3.07, no cash payment or adjustment shall be made upon any conversion on account of any interest accrued from the Interest Payment Date next preceding the conversion date, in respect of any Security (or part thereof, as the case
may be) surrendered for conversion, or on account of any dividends on the Common Stock issued upon conversion. The Company’s delivery to the Holder of the number of shares of Common Stock (and cash in lieu of fractions thereof, as provided in
this Indenture) into which a Security is convertible will be deemed to satisfy the Company’s obligation to pay (i) the principal amount of the Security and (ii) accrued but unpaid interest to, but excluding, the Conversion Date. 
  
 Securities shall be deemed to have been converted immediately prior to the
close of business on the day of surrender of such Securities for conversion in accordance with the foregoing provisions, and at such time the rights of the Holders of such Securities as Holders shall cease, and the Person or Persons entitled to
receive the Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such Common Stock at such time. As promptly as practicable on or after the Conversion Date, Holdings shall issue and deliver to
the Trustee, for delivery to the Holder (unless a different Person is indicated on the Conversion Notice), a certificate or certificates for the number of full shares of Common Stock issuable upon conversion, together with payment in lieu of any
fraction of a share, as provided in Section 15.03. 
  

 -92- 

 All shares of Common Stock delivered upon such conversion of Restricted Securities shall bear restrictive
legends substantially in the form of the legends required to be set forth on the Restricted Securities pursuant to Section 3.05 and shall be subject to the restrictions on transfer provided in such legends. Neither the Trustee nor any agent
maintained for the purpose of such conversion shall have any responsibility for the inclusion or content of any such restrictive legends on such Common Stock; provided, however, that the Trustee or any agent maintained for the purpose
of such conversion shall have provided, to Holdings or to Holdings’ transfer agent for such Common Stock, prior to or concurrently with a request to Holdings to deliver such Common Stock, written notice that the Securities delivered for
conversion are Restricted Securities. 
  
 In the case of any
Security which is converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Security or Securities of authorized denominations in
an aggregate principal amount equal to the unconverted portion of the principal amount of such Security. A Security may be converted in part, but only if the principal amount of such Security to be converted is any integral multiple of $1,000 and
the principal amount of such security to remain Outstanding after such conversion is equal to $1,000 or any integral multiple of $1,000 in excess thereof. 
  
 If shares of Common Stock to be issued upon conversion of a Restricted Security, or Securities to be issued upon conversion of a Restricted Security in
part only, are to be registered in a name other than that of the beneficial owner of such Restricted Security, then such Holder must deliver to the Conversion Agent a Surrender Certificate, dated the date of surrender of such Restricted Security and
signed by such beneficial owner, as to compliance with the restrictions on transfer applicable to such Restricted Security. Neither the Trustee nor any Conversion Agent, Registrar or Transfer Agent shall be required to register in a name other than
that of the beneficial owner, shares of Common Stock or Securities issued upon conversion of any such Restricted Security not so accompanied by a properly completed Surrender Certificate. 
  
 SECTION 15.03. Fractions of Shares. No fractional shares of Common Stock shall be issued upon conversion of any
Security or Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion thereof shall be computed on the basis of the aggregate principal
amount of the Securities (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock that would otherwise be issuable upon conversion of any Security or Securities (or specified portions thereof), the Company
shall calculate and pay a cash adjustment in respect of such fraction (calculated to the nearest 1/100th of a share) in an amount equal to the same fraction of the Closing Price at the close of business on the day of conversion. 
  
 SECTION 15.04. Adjustment of Conversion Rate. (a) The Conversion Rate
shall be subject to adjustments from time to time as follows: 
  
 (1) In case Holdings shall pay or make a dividend or other distribution on shares of Common Stock payable in shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the
date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be increased by 

  

 -93- 

 
dividing such Conversion Rate by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such increase to become effective immediately after the opening of
business on the day following the date fixed for such determination. If, after any such date fixed for determination, any dividend or distribution is not in fact paid, the Conversion Rate shall be immediately readjusted, effective as of the date the
Board of Directors of Holdings determines not to pay such dividend or distribution, to the Conversion Rate that would have been in effect if such determination date had not been fixed. For the purposes of this paragraph (1), the number of shares of
Common Stock at any time outstanding shall not include shares held in the treasury of Holdings but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. Holdings will not pay any
dividend or make any distribution on shares of Common Stock held in the treasury of Holdings. 
  
 (2) In case Holdings shall issue rights, options or warrants to all holders of its Common Stock entitling them to subscribe for or
purchase shares of Common Stock at a price per share less than the Current Market Price per share (determined as provided in paragraph (c) of this Section 15.04) of the Common Stock on the date fixed for the determination of stockholders entitled to
receive such rights, options or warrants (other than any rights, options or warrants that by their terms will also be issued to any Holder upon conversion of a Security into shares of Common Stock without any action required by Holdings or any other
Person), the Conversion Rate in effect at the opening of business on the day following the date fixed for such determination shall be increased by dividing such Conversion Rate by a fraction of which the numerator shall be the number of shares of
Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock that the aggregate of the offering price of the total number of shares of Common Stock so offered for subscription
or purchase would purchase at such Current Market Price and the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock so
offered for subscription or purchase, such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. If, after any such date fixed for determination, any such rights, options
or warrants are not in fact issued, or are not exercised prior to the expiration thereof, the Conversion Rate shall be immediately readjusted, effective as of the date such rights, options or warrants expire, or the date the Board of Directors of
Holdings determines not to issue such rights, options or warrants, to the Conversion Rate that would have been in effect if the unexercised rights, options or warrants had never been granted or such determination date had not been fixed, as the case
may be. For the purposes of this paragraph (2), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of Holdings but shall include shares issuable in respect of scrip certificates issued in lieu
of fractions of shares of Common Stock. Holdings will not issue any rights, options or warrants in respect of shares of Common Stock held in the treasury of Holdings. 
  

 -94- 

 (3) In case outstanding shares of Common Stock shall be subdivided into a greater number
of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and, conversely, in case outstanding shares of Common
Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision or combination becomes effective shall be proportionately
reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 
  
 (4) In case Holdings shall, by dividend or otherwise,
distribute to all holders of its Common Stock evidences of its indebtedness, shares of any class of capital stock or other property (including cash or assets or securities, but excluding (A) any rights, options or warrants referred to in paragraph
(a) (2) of this Section, (B) any dividend or distribution paid exclusively in cash, (C) any dividend or distribution referred to in paragraph (a)(1) of this Section and (D) any consideration distributed in any merger or consolidation to which
Section 15.11 applies), the Conversion Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion Rate in effect immediately prior to the close of business on the date fixed for the determination of
stockholders entitled to receive such distribution by a fraction of which the numerator shall be the Current Market Price per share (determined as provided in paragraph (c) of this Section 15.04) of the Common Stock on the date fixed for such
determination less the then fair market value of the portion of the assets, shares or evidences of indebtedness so distributed applicable to one share of Common Stock and the denominator shall be such Current Market Price per share of the Common
Stock, such adjustment to become effective immediately prior to the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such distribution. If after any such date fixed for determination,
any such distribution is not in fact made, the Conversion Rate shall be immediately readjusted, effective as of the date of the Board of Directors of Holdings determines not to make such distribution, to the Conversion Rate that would have been in
effect if such determination date had not been fixed. In the event Holdings distributes shares of capital stock of one of its Subsidiaries, the Conversion Rate will be adjusted, if at all, based on the market value of the Subsidiary stock so
distributed relative to the market value of the Common Stock, as described below. 
  
 The Board of Directors of Holdings shall determine fair market values for the purposes of this Section 15.04(a)(4), whose determination shall be conclusive and described in a Board Resolution filed with the Trustee;
provided, however, that in respect of a dividend or other distribution of shares of capital stock of a class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of Holdings which has a Subsidiary
Closing Price (a “Spin-off”), the fair market value of the securities to be distributed shall equal the average of the daily Subsidiary Closing Price of such securities for the five consecutive Trading Days commencing on and
including the sixth Trading Day of such securities after the effectiveness of the Spin-off; provided, further, that in the event that an underwritten initial public offering of the securities in the Spin-off occurs simultaneously with the
Spin-off, fair market value of the securities distributed in the Spin-off shall be the initial public offering price of such securities and the 

  

 -95- 

 
market price per share of the Common Stock shall mean the Closing Price for the Common Stock on the same Trading Day. 
  
 (5) In case Holdings or any of its Subsidiaries shall make a
tender offer for Common Stock and such tender offer shall expire, then, immediately prior to the opening of business on the day after the last date (the “Tender Offer Expiration Date”) tenders could have been made pursuant to such
tender offer (as such offer may have been amended), the Conversion Rate shall be increased so that the Conversion Rate shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to close of business on the Tender
Offer Expiration Date by a fraction of which the numerator shall be the sum of (x) the aggregate consideration (determined as the sum of the aggregate amount of cash consideration and the aggregate fair market value (as determined by the Board of
Directors of Holdings, whose determination shall be conclusive evidence thereof and which shall be evidenced by an Officers’ Certificate delivered to the Trustee thereof) of any other consideration) payable to stockholders based on the
acceptance (up to any maximum specified in the terms of the tender offer) of all shares validly tendered and not withdrawn as of the last time at which such tenders could have been made on the Tender Offer Expiration Date (the “Tender Offer
Expiration Time”) (the shares deemed so accepted, up to any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares and
excluding any shares held in the treasury of Holdings) at the Expiration Time and the Current Market Price per share of Common Stock (as determined in accordance with subsection (c) of this Section 15.04) on the Trading Day next succeeding the
Tender Offer Expiration Date, and the denominator shall be the product of the number of shares of Common Stock outstanding (including tendered shares but excluding any shares held in the treasury of Holdings) at the Expiration Time multiplied by the
Current Market Price per share of the Common Stock (as determined in accordance with subsection (c) of this Section 15.04) on the Trading Day next succeeding the Tender Offer Expiration Date, such increase to become effective immediately prior to
the opening of business on the day following the Tender Offer Expiration Date. In the event that Holdings is obligated to purchase shares pursuant to any such tender offer, but Holdings is permanently prevented by applicable law from effecting any
or all such purchases or any or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate which would have been in effect based upon the number of shares actually purchased. If the application of this
Section 15.04(a)(5) to any tender offer would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer under this Section 15.04(a)(5). 
  
 For purposes of this Section 15.04(a)(5), the term “tender offer” shall mean and include both tender offers and
exchange offers, all references to “purchases” of shares in tender offers (and all similar references) shall mean and include both the purchase of shares in tender offers and the acquisition of shares pursuant to exchange offers, and all
references to “tendered shares” (and all similar references) shall mean and include shares tendered in both tender offers and exchange offers. 
  
 (6) In case Holdings shall, by dividend or otherwise, make a distribution exclusively in cash to all holders of its outstanding Common
Stock (excluding any cash 

  

 -96- 

 
that is distributed as part of a distribution referred to in paragraph (a)(4) of this Section or cash distributed upon a merger or consolidation to which
Section 15.11 applies) then, and in each such case, immediately after the close of business on such date for determination, the Conversion Rate shall be adjusted to the rate determined by multiplying the Conversion Rate in effect immediately prior
to the close of business on the date fixed for determination of the stockholders entitled to receive such distribution by a fraction (X) the numerator of which shall be equal to the Current Market Price per share (determined as provided in paragraph
(c) of this Section) of the Common Stock on the date fixed for such determination plus the amount per share of such dividend or distribution and (Y) the denominator of which shall be equal to the Current Market Price per share (determined as
provided in paragraph (c) of this Section) of the Common Stock on such date fixed for determination. 
  
 (b) The reclassification of Common Stock into securities other than Common Stock (other than any reclassification upon a consolidation or merger to which
Section 15.11 applies) shall be deemed to involve (a) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be “the date fixed for the
determination of stockholders entitled to receive such distribution” and “the date fixed for such determination” within the meaning of paragraph (a)(4) of this Section), and (b) a subdivision or combination, as the case may be, of the
number of shares of Common Stock outstanding immediately prior to such reclassification into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be “the day
upon which such subdivision becomes effective” or “the day upon which such combination becomes effective”, as the case may be, and “the day upon which such subdivision or combination becomes effective” within the meaning of
paragraph (a)(3) of this Section 15.04). 
  
 (c) For the purpose
of (A) any computation under paragraphs (a)(2), (4) or (5) of this Section 15.04, the “Current Market Price” per share of Common Stock on any date shall be calculated by the Company and be the average of the daily Closing Prices for the 10
consecutive Trading Days selected by the Company commencing not more than 20 Trading Days before, and (I) in the case of paragraphs (a)(2) or (4) of this Section 15.04, ending not later than, the earlier of the date fixed for determination and the
day before the “ex-date” with respect to the issuance or distribution requiring such computation or (II) in the case of paragraph (a)(5) of this Section 15.04, ending not later than, the Tender Offer Expiration Date with respect to the
tender offer requiring such computation; and (B) any computation under paragraph (a)(6) of this Section 15.04, the “Current Market Price” per share of Common Stock on any date shall be calculated by the Company and be the average of the
daily Closing Prices for the first 10 consecutive Trading Days from and including the first “ex-date” with respect to the dividend or other distribution requiring such computation. For purposes of this paragraph, the term
“ex-date”, when used with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way in the applicable securities market or on the applicable securities exchange without the right to receive
such issuance or distribution. 
  
 (d) All calculations under
this Article shall be made to the nearest $0.01 or to the nearest one-hundredth of a share, as the case may be. 
  

 -97- 

 (e) Holdings may make such increases in the Conversion Rate, for the remaining term of the Securities or
any shorter term, in addition to those required by paragraphs (a)(1), (2), (3), (4), (5) and (6) of this Section 15.04, as its Board of Directors deems to be advisable in order to avoid or diminish any income tax to any holders of shares of Common
Stock resulting from any dividend or distribution of Capital Stock or issuance of rights or warrants to purchase or subscribe for Capital Stock or from any event treated as such for income tax purposes. The Company shall have the power to resolve
any ambiguity or correct any error in this paragraph (e) and its actions in so doing shall, absent manifest error, be final and conclusive. 
  
 (f) Notwithstanding the foregoing provisions of this Section, no adjustment of the Conversion Rate shall be required to be made (a) upon the issuance of
shares of Common Stock pursuant to any present or future plan for the reinvestment of dividends or (b) because of a tender or exchange offer of the character described in Rule 13e-4(h)(5) under the Exchange Act or any successor rule thereto.

  
 (g) To the extent permitted by applicable law, the Company
from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least 20 days, the increase is irrevocable during such period, and the Board of Directors of the Company shall have made a determination that
such increase would be in the best interests of the Company or Holdings, which determination shall be conclusive; provided, however, that no such increase shall be taken into account for purposes of determining whether the Closing
Price of the Common Stock equals or exceeds 105% of the Conversion Price in connection with an event which would otherwise be a Fundamental Change pursuant to the definition thereof. Whenever the Conversion Rate is increased pursuant to the
preceding sentence, the Company shall give notice of the increase to the Holders in the manner provided in Section 1.06 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. 
  
 (h) If at any time Holdings enacts a Rights Plan, or amends or issues additional Rights under its Rights Plan in existence on the Issue Date: (i) each share of Common Stock issued upon conversion of the Securities pursuant to this Article
XV shall be entitled to receive the appropriate number of Rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any Rights
Plan, whether or not such Rights have separated from the Common Stock, unless prior to the conversion of the Securities, such Rights have expired, or been terminated or redeemed; and (ii) if Holders of the Securities exercising the right of
conversion attaching after the date the Rights separate from the underlying Common Stock are not entitled to receive the rights that would otherwise be attributable to the shares of Common Stock received upon conversion (except in the case where any
such Holder or Holders cause, directly or indirectly, the Trigger Event), the Conversion Rate will be adjusted as though the Rights were being distributed to holders of Common Stock on the date of such separation. If such an adjustment is made and
the Rights are later redeemed, invalidated or terminated, then a corresponding reversing adjustment will be made to the Conversion Rate on an equitable basis. 
  

 -98- 

 SECTION 15.05. Notice of Adjustments of Conversion Rate.  
  
 Whenever the Conversion Rate is adjusted as herein provided: 
  
 (a) the Company shall compute the adjusted Conversion Rate
in accordance with Section 15.04 and shall prepare a certificate signed by the Chief Financial Officer of the Company setting forth the adjusted Conversion Rate and showing in reasonable detail the facts upon which such adjustment is based, and such
certificate shall promptly be filed with the Trustee and with each Conversion Agent; and 
  
 (b) upon each such adjustment, a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate
shall be required, and as soon as practicable after it is required, such notice shall be provided by the Company to all Holders in accordance with Section 1.06. 
  

Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate or the information and
calculations contained therein, except to exhibit the same to any Holder of Securities desiring inspection thereof at its office during normal business hours, and shall not be deemed to have knowledge of any adjustment in the Conversion Rate unless
and until a Responsible Officer of the Trustee shall have received such a certificate. Until a Responsible Officer of the Trustee receives such a certificate, the Trustee and each Conversion Agent may assume without inquiry that the last Conversion
Rate of which the Trustee has knowledge of remains in effect. 
  
 SECTION 15.06. Notice of Certain Corporate Action. 
  
 In case: 
  
 (a) Holdings shall
declare a dividend (or any other distribution) on its Common Stock payable (i) otherwise than exclusively in cash or (ii) exclusively in cash in an amount that would require any adjustment pursuant to Section 15.04; or 
  
 (b) Holdings shall authorize the granting to all or
substantially all of the holders of its Common Stock of rights, options or warrants to subscribe for or purchase any shares of capital stock of any class or of any other rights; or 
  
 (c) of any reclassification of the Common Stock, or of any consolidation, merger or share exchange to which
Holdings is a party and for which approval of any stockholders of Holdings is required, or of the conveyance, sale, transfer or lease of all or substantially all of the assets of Holdings; or 
  
 (d) of the voluntary or involuntary dissolution, liquidation
or winding up of Holdings; 
  
 then the Company shall cause to be filed at each
office or agency maintained for the purpose of conversion of Securities pursuant to this Indenture, and shall cause to be provided to all Holders in accordance with Section 1.06, at least 20 days (or 10 days in any case specified in clause (a) or
(b) above) prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, rights, options or warrants, or, if a record is not to
be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights, options or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, conveyance,

  

 -99- 

 
transfer, sale, lease, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common
Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, conveyance, transfer, sale, lease, dissolution, liquidation or winding
up. Neither the failure to give such notice or the notice referred to in the following paragraph nor any defect therein shall affect the legality or validity of the proceedings described in clauses (a) through (d) of this Section 15.06. If at the
time the Trustee shall not be the Conversion Agent, a copy of such notice shall also forthwith be filed by the Company with the Trustee. 
  
 The Company shall cause to be filed at the Corporate Trust Office and each office or agency maintained for the purpose of conversion of Securities
pursuant to this Indenture, and shall cause to be provided to all Holders in accordance with Section 1.06, notice of any tender offer by Holdings or any of its Subsidiaries for all or any portion of the Common Stock at or about the time that such
notice of tender offer is provided to the public generally. 
  
 SECTION 15.07. Company to Reserve Common Stock. Holdings shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of
Securities, the full number of shares of Common Stock then issuable upon the conversion of all Outstanding Securities. 
  
 SECTION 15.08. Taxes on Conversions. Except as provided in the next sentence, the Company will pay any and all taxes and duties that may be payable
in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any tax or duty that may be payable in respect of (i) income of the Holder, (ii) cash
received by the Holder in lieu of fractional shares or (iii) any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Security or Securities to be converted, and no such issue or
delivery shall be made unless and until the Person requesting such issue has paid to the Company the amount of any such tax or duty, or has established to the satisfaction of the Company that such tax or duty has been paid. 
  
 SECTION 15.09. Covenant as to Common Stock. Holdings agrees that all
shares of Common Stock that may be delivered upon conversion of Securities, upon such delivery, will have been duly authorized and validly issued and will be fully paid and nonassessable and, except as provided in Section 15.08, Holdings or the
Company shall pay all taxes, liens and charges with respect to the issue thereof. 
  
 SECTION 15.10. Cancellation of Converted Securities. All Securities delivered for conversion shall be delivered to the Trustee or its agent to be canceled by or at the direction of the Trustee, which shall
dispose of the same as provided in Section 3.09. 
  
 SECTION
15.11. Provision in Case of Consolidation, Merger or Sale of Assets. In case of any consolidation or merger of Holdings with or into any other Person, any merger of another Person with or into Holdings (other than a consolidation or merger
that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock) or any conveyance, sale or transfer of all or substantially all of the assets of Holdings 

  

 -100- 

 
(other than a conveyance, sale or transfer of all or substantially all of the assets of Holdings that does not result in any reclassification, conversion,
exchange or cancellation of outstanding shares of Common Stock), the Person formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental
indenture providing that the Holder of each Security then Outstanding shall have the right thereafter, during the period such Security shall be convertible as specified in Section 15.01, to convert such Security only into the kind and amount of
securities, cash and other property receivable upon such consolidation, merger, conveyance, sale or transfer by a holder of the number of shares of Common Stock into which such Security might have been converted immediately prior to such
consolidation, merger, conveyance, sale or transfer assuming such holder of Common Stock (i) is not (A) a Person with which Holdings consolidated or merged with or into or which merged into or with Holdings or to which such conveyance, sale or
transfer was made, as the case may be (a “Constituent Person”), or (B) an Affiliate of a Constituent Person and (ii) failed to exercise his rights of election, if any, as to the kind or amount of securities, cash and other property
receivable upon such consolidation, merger, conveyance, sale or transfer (provided that if the kind or amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale or transfer is not the same for
each share of Common Stock held immediately prior to such consolidation, merger, conveyance, sale or transfer by others than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised
(“Non-electing Share”), then for the purpose of this Section 15.11 the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale or transfer by the holders of each
Non-electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-electing Shares). Such supplemental indenture shall provide for adjustments that, for events subsequent to the effective date of such
supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article XV. The above provisions of this Section 15.11 shall similarly apply to successive consolidations, mergers, conveyances,
sales or transfers. Notice of the execution of such a supplemental indenture shall be given by the Company to the Holder of each Security as provided in Section 1.06 promptly upon such execution. 
  
 Neither the Trustee nor any Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any such supplemental indenture relating either to the kind or amount of shares of stock or other securities or property or cash receivable by Holders of Securities upon the
conversion of their Securities after any such consolidation, merger, conveyance, transfer or sale or to any such adjustment, but may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, an
Opinion of Counsel with respect thereto, which the Company shall cause to be furnished to the Trustee upon request. 
  
 SECTION 15.12. Rights Issued in Respect of Common Stock. Rights or warrants distributed by Holdings to all holders of Common Stock entitling the
holders thereof to subscribe for or purchase shares of the Common Stock (either initially or under certain circumstances specified in the documents governing such rights or warrants), which rights or warrants, until the occurrence of such certain
circumstances (“Trigger Event”): 
  
 (a) are deemed to be transferred with such shares of Common Stock, 
  

 -101- 

 (b) are not exercisable, and 
  
 (c) are also issued in respect of future issuances of Common
Stock 
  
 shall not be deemed distributed for purposes of Section 15.04(a)(2)
until the occurrence of the earliest Trigger Event. In addition, in the event of any distribution of rights or warrants, or any Trigger Event with respect thereto, that shall have resulted in an adjustment to the Conversion Rate under Section
15.04(a)(2), (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to
such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of Common Stock with respect to such rights or warrants (assuming such holder
had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase and (2) in the case of any such rights or warrants all of which shall have expired without exercise by any holder thereof, the
Conversion Price shall be readjusted as if such issuance had not occurred. 
  
 SECTION 15.13. Responsibility of Trustee for Conversion Provisions. The Trustee, subject to the provisions of Section 6.01, and any Conversion Agent shall not at any time be under any duty or responsibility to
any Holder of Securities to determine whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed, herein or in any
supplemental indenture provided to be employed, in making the same, or whether a supplemental indenture need be entered into. Neither the Trustee, subject to the provisions of Section 6.01, nor any Conversion Agent shall be accountable with respect
to the validity or value (or the kind or amount) of any Common Stock, or of any other securities or property or cash, which may at any time be issued or delivered upon the conversion of any Security; and it or they do not make any representation
with respect thereto. Neither the Trustee, subject to the provisions of Section 6.01, nor any Conversion Agent shall be responsible for any failure of the Company to make or calculate any cash payment or to issue, transfer or deliver any shares of
Common Stock or share certificates or other securities or property or cash upon the surrender of any Security for the purpose of conversion; and the Trustee, subject to the provisions of Section 6.01, and any Conversion Agent shall not be
responsible for any failure of the Company to comply with any of the covenants of the Company contained in this Article. 
  
 This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

	 	RE:	1 7/8% CONVERTIBLE SENIOR SUBORDINATED NOTES
DUE OCTOBER 15, 2023, OF UNITED RENTALS (NORTH AMERICA), INC. (THE “SECURITIES”) 

  
 Reference is made to the Indenture, dated as of October 31, 2003 (the “Indenture”), from UNITED RENTALS (NORTH AMERICA), INC. (the
“Company”) to THE BANK OF NEW YORK, as Trustee. Terms used herein and defined in the Indenture or in Rule 144 under the U.S. Securities Act of 1933 (the “Securities Act”) are used herein as so defined. 
  
 This certificate relates to
$                     principal amount of Securities, which are evidenced by the following certificate(s) (the “Specified
Securities”): 
  
 CUSIP No.
                     
  
 CERTIFICATE No(s).
                     
  
 The person in whose name this certificate is executed below (the “Undersigned”) hereby certifies that either (i) it is the sole beneficial owner
