available funds to pay such principal or interest when due. The Issuers shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by
the Paying Agent for the payment of principal, premium or Additional Interest, if any, or interest on the Notes, and will notify the Trustee in writing of any default by the Issuers in making any such payment. While any such default continues, the
Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuers at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon payment
over to the Trustee, the Paying Agent (if other than an Issuer or a Subsidiary of an Issuer) shall have no further liability for the money. If an Issuer or a Subsidiary of an Issuer acts as Paying Agent, it shall segregate and hold in a separate
trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to either of the Issuers, the Trustee shall serve as Paying Agent for the Notes.

payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof).

 (v) The Registrar shall not be required (A) to issue, to
register the transfer of or to exchange any Notes during a period beginning at the opening of 15 business days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of

Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuers shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements
are met. If required by the Trustee or the Issuers, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuers to protect the Issuers, the Trustee, any Agent and any Authenticating Agent from
any loss that any of them may suffer if a Note is replaced. The Issuers may charge for their expenses in replacing a Note. 
  
 Every replacement Note is an additional obligation of the Issuers and any other obligor upon the Notes and shall be entitled to all of the benefits of
this Indenture equally and proportionately with all other Notes duly issued hereunder. 
  
 SECTION 2.08. Outstanding Notes 
  
 The
Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the
provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because an Issuer or an Affiliate of an Issuer holds the Note; however, Notes held by an
Issuer or a Subsidiary of an Issuer shall not be deemed to be outstanding for purposes of Section 3.07(b) hereof. 
  
 If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced
Note is held by a bona fide purchaser. 
  

 34 








 If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be
outstanding and interest on it ceases to accrue. 
  
 If the Paying
Agent (other than an Issuer, a Subsidiary of an Issuer or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no
longer outstanding and shall cease to accrue interest. 
  
 SECTION 2.09.

 In determining whether the Holders
of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by an Issuer, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with either of
the Issuers, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned shall
be so disregarded. 
  
 SECTION 2.10. Temporary Notes 
  
 Until certificates representing Notes are ready for delivery, the Issuers
may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Issuers consider appropriate for
temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. 
  
 Holders of temporary Notes shall be entitled to all of the benefits of this
Indenture. 
  
 SECTION 2.11. Cancellation 
  
 The Issuers at any time may deliver Notes to the Trustee for cancellation.

payment, replacement or cancellation and shall destroy canceled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes shall be delivered to the Issuers. The Issuers may not
issue new Notes to replace Notes that they have paid or that have been delivered to the Trustee for cancellation.

 If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select
the Notes to be redeemed or purchased among the Holders of the Notes in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by
lot or in accordance with any other method the Trustee shall deem fair and appropriate; provided that no Notes of $1,000 in aggregate principal amount at maturity or less shall be redeemed in part. In the event of partial redemption by lot,
the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption. 

 

 36 








 The Trustee shall promptly notify the Issuers in writing of the Notes selected for redemption and, in the
case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be
redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption. 
  
 SECTION 3.03. Notice
of Redemption 
  
 Subject to the provisions of Section
3.09 hereof, at least 30 days but not more than 60 days before a redemption date, the Issuers shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address,
except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. 
  
 The notice shall identify the Notes to be redeemed and shall state:

  
 (a) the redemption date; 
  
 (b) the redemption price; 
  
 (c) if any Note is being redeemed in part, the portion of
the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note;

  
 (d) the name and address of the Paying Agent;

  
 (e) that Notes called for redemption must be
surrendered to the Paying Agent to collect the redemption price; 
  
 (f) that, unless the Issuers default in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date; 
  
 (g) the paragraph of the Notes and/or Section of this
Indenture pursuant to which the Notes called for redemption are being redeemed; and 
  
 (h) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the
Notes. 
  
 At the Issuers’ request, the Trustee shall give
the notice of redemption in the Issuers’ name and at their expense; provided, however, that the Issuers shall have delivered to the Trustee, at least 45 days prior to the redemption date, an Officers’ Certificate requesting that the
Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 
  
 SECTION 3.04. Effect of Notice of Redemption 
  
 Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price. A notice of redemption may not be conditional.

 SECTION 3.05. Deposit of Redemption Price 
  
 One Business Day prior to the redemption date, the Issuers shall deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in
excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed. 
  
 If the Issuers comply with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the
portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was
registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuers to comply with the preceding paragraph, interest shall be paid on the
unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 
  
 SECTION 3.06. Notes Redeemed in Part

Notes tendered are in excess of the Excess Proceeds) (which maximum principal amount of Notes shall be the “Offer Amount”) or, if less than the Offer Amount has been tendered, all Notes and Pari Passu Notes tendered in response to
the Asset Sale Offer. Payment for any Notes so purchased shall be made in the same manner as interest payments are made. 
  
 If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest shall be

Holder is withdrawing his election to have such Note purchased; 
  
 (h) that, if the aggregate principal amount (or accreted value, as applicable) of Notes and Pari Passu Notes tendered by Holders exceeds the Offer Amount, the Issuers shall select the Notes and Pari Passu Notes to be
purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Issuers so that only Notes in denominations of $1,000, or integral multiples thereof, shall be purchased); and 
  
 (i) that Holders whose Notes were purchased only in part
shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). 
  
 On or before the Purchase Date, the Issuers shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount
of Notes and Pari Passu Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes, Pari Passu Notes or portions thereof tendered, and shall deliver to the Trustee an
Officers’ Certificate stating that such Notes, and Pari Passu Notes or portions thereof were accepted for payment by the Issuers in accordance with the terms of this Section 3.09. The Issuers, the Depositary or the Paying Agent, as the case may

permit any of its Subsidiaries to, enter into, or suffer to exist, any transaction or arrangement, with a Subsidiary that is an Unrestricted Subsidiary that would be inconsistent with or violate the terms set forth in the definition of
“Unrestricted Subsidiary.” 
  
 The amount of all
Restricted Payments (other than cash), including the amount of the Restricted Payment that will be deemed to occur upon the designation of a Subsidiary as an Unrestricted Subsidiary, shall be the fair market value on the date of the Restricted
Payment of the asset(s) or securities proposed to be transferred or issued by the Co-Issuer or the applicable Restricted Subsidiary, or of the Co-Issuer’s proportionate interest in the Subsidiary so to be designated as the case may be, pursuant
to the Restricted Payment. 
  
 SECTION 4.08. Limitation on Dividends and
Other Distributions from Restricted Subsidiaries 
  
 The
Co-Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted
Subsidiary to (i) (a) pay dividends or make any other 

  

 45 








 
distributions to the Co-Issuer or any of its Restricted Subsidiaries (x) on its Capital Stock or (y) with respect to any other interest or participation in,
or measured by, its profits, or (b) pay any indebtedness owed to the Co-Issuer or any of its Restricted Subsidiaries; (ii) make loans or advances to the Co-Issuer or any of its Restricted Subsidiaries; or (iii) transfer any of its properties or
assets to the Co-Issuer or any of its Restricted Subsidiaries. 
  
 However, the foregoing restrictions will not apply to encumbrances or restrictions existing under or by reason of (a) any agreement or instrument governing Existing Indebtedness as in effect on the Issue Date or as amended, modified,
restated or renewed in any manner not materially more restrictive, taken as a whole, (b) the Indenture and the Notes, (c) applicable law, (d) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Co-Issuer or any of its
Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person,
or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the Indenture to be incurred, (e) by
reason of customary non-assignment provisions in leases or licenses or other contracts entered into in the ordinary course of business, (f) purchase money obligations for property acquired in the ordinary course of business that impose restrictions
of the nature described in clause (iii) above on the property so acquired, (g) the provisions of agreements governing Indebtedness incurred pursuant to clause (iv) of the second paragraph of Section 4.09, (h) any agreement for the sale of a
Restricted Subsidiary that restricts that Restricted Subsidiary pending its sale, (i) any Credit Facility or Permitted Refinancing Indebtedness, provided that the restrictions contained in such Credit Facility or the agreements governing such
Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the Senior Credit Facility as of the Issue Date with respect to a Credit Facility, or the agreements governing the Indebtedness being
refinanced with respect to Permitted Refinancing Indebtedness, as applicable, (j) Liens permitted to be incurred pursuant to the provisions of Section 4.12 that limit the right of the debtor to transfer the assets subject to such Liens, (k) any
Indebtedness incurred in compliance with Section 4.09 or any agreement pursuant to which such Indebtedness is issued if the encumbrance or restriction applies only in the event of a payment default or default with respect to a financial covenant
contained in the Indebtedness or agreement and the encumbrance or restriction is not materially more disadvantageous to the Holders of the Notes than is customary in comparable financings (as determined by the Co-Issuer) and the Co-Issuer determines
that any such encumbrance or restriction will not materially affect the Co-Issuer’s ability to pay interest or principal on the Notes, (l) provisions with respect to the disposition or distribution of assets or property in joint venture
agreements and other similar agreements and (m) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business. 
  
 SECTION 4.09. Limitation on Incurrence of Indebtedness and Issuance of Preferred Stock 
  
 The Co-Issuer shall not, and shall not permit any of its Restricted
Subsidiaries to, directly, or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including
Acquired Debt) and the Co-Issuer and the Company will not issue any Disqualified Stock and will not permit any of the Co-Issuer’s Restricted Subsidiaries (other than the Company) to issue any shares of preferred stock; provided, however, that
(x) the Co-Issuer may incur Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock if (1) no Default shall have occurred and be continuing or would occur as a consequence thereof and (2) the Co-Issuer’s Debt to Adjusted
Consolidated Cash Flow Ratio at the time of incurrence of such Indebtedness or the issuance of such Disqualified Stock, after giving pro forma effect to such incurrence or issuance as of such date and to the use of proceeds therefrom, would have
been no greater than 7.75 to 1.0 and (y) the Company may incur Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock and the other Restricted Subsidiaries of the Co-Issuer may incur 

  

 46 








 
Indebtedness or issue preferred stock if, in each case, (1) no Default shall have occurred and be continuing or would occur as a consequence thereof, (2) the
Company’s Debt to Adjusted Consolidated Cash Flow Ratio at the time of incurrence of such Indebtedness or the issuance of such Disqualified Stock or preferred stock, after giving pro forma effect to such incurrence or issuance as of such date
and to the use of proceeds therefrom, would have been no greater than 4.0 to 1.0. 
  
 The first paragraph of this covenant shall not apply to the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”) if no Default shall have occurred and be
continuing or would occur as a consequence thereof: 
  
 (i) the incurrence by the Co-Issuer or any of its Restricted Subsidiaries of Indebtedness under one or more Credit Facilities or through the issuance of Seller Paper in an aggregate principal amount (with letters of credit being deemed to
have an aggregate principal amount equal to the maximum potential liability of the Co-Issuer and its Restricted Subsidiaries thereunder) at any one time outstanding not to exceed $300.0 million less, (i) the aggregate amount of commitment reductions
under Credit Facilities resulting from the application of proceeds of Asset Sales since the Issue Date and (ii) the aggregate amount of outstanding Consolidated Indebtedness of the Company incurred pursuant to the first paragraph of this covenant;
provided, however, that the aggregate principal amount of Seller Paper at any one time outstanding under this clause (i) shall not exceed $50.0 million; 
  
 (ii) the incurrence by the Co-Issuer and its Restricted Subsidiaries of Existing Indebtedness; 
  
 (iii) the incurrence by the Issuers of Indebtedness
represented by the Notes (other than the Additional Notes) and the Exchange Notes issued in exchange therefor; 
  
 (iv) the incurrence by the Co-Issuer or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations,
mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Co-Issuer
or such Restricted Subsidiary, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any other Indebtedness incurred pursuant to this clause (iv), not to exceed $10.0 million at
any one time outstanding; 
  
 (v) the incurrence
by the Co-Issuer or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund, Indebtedness (other than intercompany
Indebtedness) that was permitted by the Indenture to be incurred under the first paragraph hereof or clause (ii) or (iii) or this clause (v) of this paragraph; 
  

(vi) the incurrence by the Co-Issuer or any of its Restricted Subsidiaries of intercompany Indebtedness or intercompany preferred stock
between or among the Co-Issuer and any of its Restricted Subsidiaries; provided, however, that (1) if an Issuer is the obligor on such Indebtedness, such Indebtedness is expressly subordinated to the prior payment in full in cash of all Obligations
with respect to the Notes and (2)(A) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness or preferred stock being held by a Person other than the Co-Issuer or a Restricted Subsidiary and (B) any sale or
other transfer of any such Indebtedness or preferred stock 

  

 47 








 
to a Person that is not either the Co-Issuer or a Restricted Subsidiary shall be deemed, in each case, to constitute an incurrence of such Indebtedness or
issuance of such preferred stock by the Co-Issuer or such Restricted Subsidiary, as the case may be; 
  
 (vii) the incurrence by the Co-Issuer or any of its Restricted Subsidiaries of Hedging Obligations that are incurred for the purpose of
fixing or hedging interest rate risk with respect to any floating rate Indebtedness that is permitted by the terms of the Indenture to be outstanding or currency exchange risk or otherwise entered into for bona fide purposes designed to protect
against interest rate or currency exchange risk and not for speculative purposes; 
  
 (viii) the Guarantee by the Co-Issuer or any of its Restricted Subsidiaries of Indebtedness of the Company or any other Restricted
Subsidiary of the Co-Issuer that was permitted to be incurred by another provision of the Indenture; 
  
 (ix) the incurrence by the Co-Issuer or any of its Restricted Subsidiaries of Acquired Debt in connection with the acquisition of assets
or a new Subsidiary and the incurrence by the Co-Issuer’s Restricted Subsidiaries of Indebtedness as a result of the designation of an Unrestricted Subsidiary as a Restricted Subsidiary; provided that, in the case of any such incurrence of
Acquired Debt, such Acquired Debt was incurred by the prior owner of such assets or such Restricted Subsidiary prior to such acquisition by the Co-Issuer or one of its Restricted Subsidiaries and was not incurred in connection with, or in
contemplation of, such acquisition by the Co-Issuer or one of its Restricted Subsidiaries; and provided further that as a result of such incurrence, in the case of Acquired Debt incurred directly by the Co-Issuer, the Co-Issuer’s Debt to
Adjusted Consolidated Cash Flow Ratio and, in the case of Acquired Debt incurred by the Company or any other Restricted Subsidiary of the Co-Issuer, the Co-Issuer’s Debt to Adjusted Consolidated Cash Flow Ratio and the Company’s Debt to
Adjusted Consolidated Cash Flow Ration, in each case, at the time of incurrence of such Acquired Debt, after giving pro forma effect to such incurrence as if the same had occurred at the beginning of the most recently ended four full fiscal quarter
period for the Co-Issuer for which internal financial statements are available, would have been less than or equal to, in the case of Acquired Deb t incurred directly by the Co-Issuer, the Co-Issuer’s Debt to Adjusted Consolidated Cash Flow
Ratio and, in the case of Acquired Debt incurred by the Company or any other Restricted Subsidiary of the Co-Issuer, the Co-Issuer’s Debt to Adjusted Consolidated Cash Flow Ratio and the Company’s Debt to Adjusted Consolidated Cash Flow
Ratio, respectively, for the same period without giving pro forma effect to such incurrence; 
  
 (x) the incurrence by the Co-Issuer or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or
accreted value, as applicable) at any time outstanding not to exceed $10.0 million. 
  
 The Co-Issuer shall not permit any of its Unrestricted Subsidiaries to incur any Indebtedness other than Non-Recourse Debt; and Restricted Subsidiaries may not issue or sell, and the Co-Issuer may not permit any
Restricted Subsidiary to have outstanding, any Equity Interests (other than (x) Equity Interests held by the Co-Issuer or its Restricted Subsidiaries or (y) Permitted Subsidiary Equity Interests). 
  
 For purposes of determining compliance with this Section 4.09, in the event
that an item of Indebtedness or preferred stock meets the criteria of more than one of the categories of Permitted Debt described in clauses (i) through (x) in the second paragraph of this Section 4.09 or is entitled to be 

  

 48 








 
incurred pursuant to the first paragraph of this Section 4.09, the Issuers may, from time to time, in their sole discretion, classify or reclassify such item
of Indebtedness in any manner that complies with this Section 4.09. Accrual of interest, accretion or amortization of original issue discount and the payment of interest in the form of additional Indebtedness will not be deemed to be an incurrence
of Indebtedness for purposes of this covenant. 
  
 SECTION 4.10. Limitation
on Asset Sales 
  
 The Co-Issuer shall not, and shall not
permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless (i) the Co-Issuer (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value
(evidenced by a resolution of the Board of Directors set forth in an Officers’ Certificate delivered to the Trustee) of the assets or Equity Interests issued or sold or otherwise disposed of and (ii) at least 75% of the consideration therefor
received by the Co-Issuer or such Restricted Subsidiary is in the form of (a) cash or Cash Equivalents, (b) Tower Assets or (c) any combination of the foregoing. For purposes of this provision, the following shall be deemed to be cash for purposes
of this provision: the amount of (x) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet) of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that
are by their terms subordinated to the Notes or any guarantee thereof) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability
and (y) any securities, notes or other obligations received by the Co-Issuer or any such Restricted Subsidiary from such transferee that are converted by the Co-Issuer or such Restricted Subsidiary into cash within 20 days of the applicable Asset
Sale (to the extent of the cash received). 
  
 Within 360 days
after the receipt of any Net Proceeds from an Asset Sale, the Co-Issuer or the applicable Restricted Subsidiary may apply such Net Proceeds to: (a) reduce (which reduction may be temporary) Indebtedness under a Credit Facility; (b) reduce or
repurchase any Indebtedness of any Restricted Subsidiary of the Company; (c) reduce or repurchase any Indebtedness represented by the Notes; (d) reduce or repurchase any Senior Indebtedness of the Company; provided that the Notes are reduced or
repurchased on a pro rata basis with the Net Proceeds from such Asset Sale; (e) acquire all or substantially all the assets of a Permitted Business; provided, that after giving effect thereto, the Company or a Restricted Subsidiary of the Company is
the owner of such assets; (f) acquire Voting Stock of a Permitted Business from a Person that is not a Subsidiary of the Company; provided, that, after giving effect thereto, the Company and its Restricted Subsidiaries own a majority of such Voting
Stock; or (g) make a capital expenditure or acquire other long-term assets that are used or useful in a Permitted Business; provided, that after giving effect thereto, the Company or a Restricted Subsidiary of the Company is the owner of such
assets. Pending the final application of any such Net Proceeds, the Co-Issuer or the applicable Restricted Subsidiary may invest such Net Proceeds in any manner that is not prohibited by the Indenture. 
  
 Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph will be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Co-Issuer or the applicable Restricted Subsidiary will be required to make
an offer (an “Asset Sale Offer”) to all Holders of Notes and all holders of other Senior Indebtedness of the Company containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem
with the proceeds of sales of assets (such other Senior Indebtedness, “Pari Passu Notes”) to purchase the maximum principal amount (or accreted value, as applicable) of Notes and such Pari Passu Notes that may be purchased out of
the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount (or accreted value, as applicable) thereof plus accrued and unpaid interest thereon and Additional Interest, if any, to the date of purchase (subject
to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), in 

  

 49 








 
accordance with the procedures set forth in the Indenture and the instruments governing such Pari Passu Notes. 
  
 To the extent that any Excess Proceeds remain after consummation of an Asset
Sale Offer, the Co-Issuer may use such Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount (or accreted value, as applicable) of Notes and Pari Passu Notes tendered into such Asset Sale Offer
surrendered by holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and Pari Passu Notes to be purchased on a pro rata basis based on the aggregate principal amount (or accreted value, as applicable) of Notes and
Pari Passu Notes tendered. Upon completion of such offer to purchase, the amount of Excess Proceeds shall be reset at zero. 
  
 The Co-Issuer will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or
regulations applicable to any Asset Sale Offer. To the extent that the provisions of any such securities laws or securities regulations conflict with the provisions of the covenant described above, the Co-Issuer will comply with the applicable
securities laws and regulations and will not be deemed to have breached its obligations under the covenant described above by virtue thereof. 
  
 SECTION 4.11. Limitation on Transactions with Affiliates 
  
 The Co-Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of
any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate (each of the
foregoing, an “Affiliate Transaction”), unless (i) such Affiliate Transaction is on terms that are no less favorable to the Co-Issuer or the relevant Restricted Subsidiary than those that would have been obtained in a comparable
transaction by the Co-Issuer or such Restricted Subsidiary with an unrelated Person and (ii) the Co-Issuer delivers to the Trustee (a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $2.5 million, a resolution of the Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (i) above and that such Affiliate Transaction has been
approved by a majority of the disinterested members of the Board of Directors and (b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, an opinion as
to the fairness to the Holders of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. Notwithstanding the foregoing, the following items shall not be deemed to
be Affiliate Transactions: (i) any employment arrangements with any executive officer of the Co-Issuer or a Restricted Subsidiary that is entered into by the Co-Issuer or any of its Restricted Subsidiaries in the ordinary course of business and
consistent with compensation arrangements of similarly situated executive officers at comparable companies engaged in Permitted Businesses, (ii) transactions between or among the Co-Issuer and/or its Restricted Subsidiaries, (iii) payment of outside
directors’ fees in an aggregate annual amount not to exceed $50,000 per Person, (iv) Restricted Payments and Permitted Investments that are permitted by Section 4.07 and (v) the issuance or sale of Equity Interests (other than Disqualified
Stock) of the Co-Issuer. 
  
 SECTION 4.12. Limitation on Liens

  
 The Co-Issuer shall not, and shall not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien securing Indebtedness or trade payables on any asset now owned or hereafter acquired, or any income or profits therefrom or assign or convey any
right to receive income therefrom (except for Permitted Liens), unless (A) in the case of the Liens securing Indebtedness that is expressly subordinate or junior in right of payment to the Notes, the Notes are 

  

 50 








 
secured by a Lien on those assets or income or profits that is senior in priority to those Liens, with the same relative priority as that subordinate or
junior Indebtedness will have with respect to the Notes and (B) in all other cases, the Notes are secured on an equal and ratable basis, in each case, until such time as such Indebtedness is no longer secured by a Lien. 
  
 SECTION 4.13. Limitation on Business Activities 
  
 The Co-Issuer shall not, and shall not permit any Restricted Subsidiary to,
engage in any business other than Permitted Businesses, except to such extent as would not be material to the Co-Issuer and its Restricted Subsidiaries taken as a whole. 
  
 SECTION 4.14. Corporate Existence 
  
 Subject to Article 5 hereof, the Co-Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect (i) its
corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Co-Issuer or any such
Restricted Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Co-Issuer and its Subsidiaries; provided, however, that the Co-Issuer shall not be required to preserve any such right, license or franchise, or the
corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Co-Issuer and its Restricted
Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes. 
  
 SECTION 4.15. Offer to Repurchase upon Change of Control 
  
 (a) Upon the occurrence of a Change of Control, each Holder of Notes shall have the right to require the Issuers to purchase all or any
part (equal to $1,000 in principal amount at maturity or an integral multiple thereof) of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”) at an offer price in cash equal to 101% of the
aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest thereon, if any (subject to the right of Holders of record on the relevant record date to receive interest and Additional Interest, if any, due on the
relevant interest payment date), to the date of purchase or, in the case of purchases of Notes prior to the Full Accretion Date, at a purchase price equal to 101% of the Accreted Value thereof plus accrued and unpaid interest and Additional Interest
thereon, if any (subject to the right of Holders of record on the relevant record date to receive interest and Additional Interest, if any, due on the relevant interest payment date), to the date of purchase (the “Change of Control
Payment”). Within 30 days following any Change of Control, the Issuers shall mail a notice to each Holder stating: (i) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered will be accepted
for payment; (ii) the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”); (iii) that any Note not
tendered will continue to accrete or accrue interest; (iv) that, unless the Issuers default in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrete or accrue
interest after the Change of Control Payment Date; (v) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect
Purchase” on the reverse of the Notes completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date; (vi) that Holders will be
entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the
name of the Holder, the principal amount of Notes delivered for purchase, and a 

  

 51 








 
statement that such Holder is withdrawing his election to have the Notes purchased; and (vii) that Holders whose Notes are being purchased only in part will
be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in principal amount or an integral multiple thereof. 
  
 (b) On the Change of Control Payment Date, the Issuers
shall, to the extent lawful, (i) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes
or portions thereof so tendered and (iii) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the
Issuers. The Paying Agent shall promptly mail to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note
equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note shall be in a principal amount of $1,000 or an integral multiple thereof. 
  
 (c) The Issuers shall not be required to make a Change of
Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the
Issuers and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. The provisions under this Indenture relative to the Issuers’ obligations to make an offer to repurchase the Notes as a result of a Change of
Control may be waived or modified with the written consent of the Holders of a majority in principal amount at maturity of the Notes then outstanding. 
  
 (d) The Issuers shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other
securities laws or regulations applicable to any Change of Control Offer. To the extent that the provisions of any such securities laws or securities regulations conflict with the provisions of the covenant described above, the Issuers shall comply
with the applicable securities laws and regulations and shall not be deemed to have breached their obligations under the covenant described above by virtue thereof. 
  
 SECTION 4.16. Limitation on Sale and Leaseback Transactions 
  
 The Co-Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback
transaction (as seller); provided that the Co-Issuer or any of its Restricted Subsidiaries may enter into a sale and leaseback transaction if (i) the Co-Issuer or such Restricted Subsidiary, as applicable, could have (a) incurred Indebtedness in an
amount equal to the Attributable Debt relating to such sale and leaseback transaction (x), in the case of the Co-Issuer, pursuant to the Co-Issuer’s Debt to Adjusted Consolidated Cash Flow Ratio test set forth in the first paragraph of Section
4.09 and (y), in the case of the Company and any other Restricted Subsidiary of the Co-Issuer, pursuant to the Company’s Debt to Adjusted Consolidated Cash Flow Ratio test set forth in the first paragraph of Section 4.09 and (b) incurred a Lien
to secure such Indebtedness pursuant to Section 4.12, (ii) the gross cash proceeds of such sale and leaseback transaction are at least equal to the fair market value (as determined in good faith by the Board of Directors) of the property that is the
subject of such sale and leaseback transaction and (iii) the transfer of assets in such sale and leaseback transaction is permitted by, and the Co-Issuer applies the proceeds of such transaction in compliance with, Section 4.10. 
  
 SECTION 4.17. Future Subsidiary Guarantors. 
  
 The Co-Issuer will not permit the Company or any other Restricted Subsidiary
of the Co-Issuer, directly or indirectly, to Guarantee any Indebtedness of the Co-Issuer (except the Indebtedness of the Co- 

  

 52 








 
Issuer under a guarantee of Indebtedness of one or more of its Restricted Subsidiaries). The Co-Issuer will not permit any Restricted Subsidiary of the
Co-Issuer, directly or indirectly, to Guarantee any Indebtedness of the Company (except the Indebtedness of the Company under a guarantee of Indebtedness of one or more of the Company’s Restricted Subsidiaries) unless such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture to the Indenture providing for the Guarantee of the payment of the principal of, premium and Additional Interest, if any, and interest on the Notes by such Restricted Subsidiary, which
Guarantee shall be (1) senior to or pari passu with such Restricted Subsidiary’s Guarantee of or pledge to secure such other Senior Indebtedness of the Company and (2) senior to such Restricted Subsidiary’s Guarantee of or pledge to
secure such Subordinated Obligations of the Company. 
  
 Notwithstanding the foregoing, any such Guarantee by a Restricted Subsidiary of the Notes shall provide by its terms that it shall be automatically and unconditionally released and discharged upon any sale, exchange or transfer, to any
Person other than a Restricted Subsidiary of the Co-Issuer, of all of the Co-Issuer’s stock in, or all or substantially all the assets of, such Restricted Subsidiary, which sale, exchange or transfer is made in compliance with the applicable
provisions of the Indenture. 
  
 ARTICLE 5. 
  
 SUCCESSORS 
  
 SECTION 5.01. Merger, Consolidation or Sale of Assets 
  
 Neither of the Issuers may consolidate or merge with or into (whether or not
such Issuer is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions to another corporation, Person or entity unless (i)
such Issuer is the surviving corporation or the entity or the Person formed by or surviving any such consolidation or merger (if other than such Issuer) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have
been made is a corporation organized and existing under the laws of the United States, any state thereof or the District of Columbia; (ii) the entity or Person formed by or surviving any such consolidation or merger (if other than such Issuer) or
the entity or Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the obligations of such Issuer under the Notes, this Indenture and Registration Rights Agreement pursuant to
agreements in a form reasonably satisfactory to the Trustee; (iii) immediately after such transaction no Default or Event of Default exists; and (iv) immediately after the transaction and after giving pro forma effect thereto (except as otherwise
specified in clause (b) below) as if the transaction had occurred at the beginning of the applicable four-quarter period, (a) such Issuer or the entity or Person formed by or surviving any such consolidation or merger (if other than such Issuer) or
to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made will be permitted to incur at least $1.00 of additional Indebtedness pursuant to, in the case of the Co-Issuer or its successor Person, the
Co-Issuer’s Debt to Adjusted Consolidated Cash Flow Ratio test or, in the case of the Company or its successor Person, the Company’s Debt to Adjusted Consolidated Cash Flow Ratio test, in each case, set forth in the first paragraph of
Section 4.09 or (b) in the case of the Co-Issuer or its successor Person, the Co-Issuer’s Debt to Adjusted Consolidated Cash Flow Ratio and, in the case of the Company or its successor Person, the Co-Issuer’s Debt to Adjusted Consolidated
Cash Flow Ratio and the Company’s Debt to Adjusted Consolidated Cash Flow Ratio, in each case, shall be less than or equal to, in the case of the Co-Issuer or its successor Person, the Co-Issuer’s Debt to Adjusted Consolidated Cash Flow
Ratio and, in the case of the Company or its successor Person, the Co-Issuer’s Debt to Adjusted Consolidated 

  

 53 








 
Cash Flow Ratio and the Company’s Debt to Adjusted Consolidated Cash Flow Ratio, respectively, for the same period without giving pro forma effect to
such transaction.

assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this
Indenture referring to such Issuer shall refer instead to the successor corporation and not to such Issuer), and may exercise every right and power of such Issuer under this Indenture with the same effect as if such successor Person had been named

 54 








 
or is created after the Issue Date, which default (a) is caused by a failure to pay principal of or premium, if any, or interest on such Indebtedness prior
to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”) or (b) results in the acceleration of such Indebtedness prior to its Stated Maturity and, in each case, the
principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $10.0 million or more;

 SECTION 6.02. Acceleration 
  
 If any
Event of Default (other than an Event of Default specified in clause (g) or (h) of Section 6.01 hereof) occurs and is continuing, the Trustee, by notice to the Issuers, or the Holders of at least 25% in principal amount at maturity of the then
outstanding Notes, by notice to the Issuers and the Trustee, may declare all the Notes to be due and payable immediately. Upon any such declaration, the principal of 

  

 55 








 
(or, if prior to the Full Accretion Date, the Accreted Value of), premium, if any, and accrued and unpaid interest, if any, and Additional Interest, if any,
shall become due and payable immediately. Notwithstanding the foregoing, if an Event of Default specified in clause (g) or (h) of Section 6.01 hereof occurs, the principal of (or, if prior to the Full Accretion Date, the Accreted Value of) and
accrued and unpaid interest, if any, and Additional Interest, if any, shall be due and payable immediately without further action or notice. The Holders of a majority in aggregate principal amount of the Notes then outstanding by written notice to
the Trustee may on behalf of the Holders of all the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in payment of interest or premium or Additional
Interest on, or the principal of, the Notes. 
  
 SECTION 6.03. Other
Remedies 
  
 If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, interest and Additional Interest, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

  
 The Trustee may maintain a proceeding even if it does not
possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
  
 SECTION 6.04. Waiver of Past Defaults 
  
 Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of
all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest or Additional Interest on, the Notes
(including in connection with an offer to purchase) (provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related
payment default that resulted from such acceleration). 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 6.05. Control by Majority 
  
 Holders of a majority in principal amount at maturity of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in
personal liability. 
  
 SECTION 6.06. Limitation on Suits

  
 A Holder of a Note may pursue a remedy with respect to
this Indenture or the Notes only if: 
  
 (a) the
Holder of a Note gives to the Trustee written notice of a continuing Event of Default; 
  

 56 








 (b) the Holders of at least 25% in principal amount at maturity of the then outstanding
Notes make a written request to the Trustee to pursue the remedy; 
  
 (c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; 
  
 (d) the Trustee does not comply with the request within 60
days after receipt of the request and the offer and, if requested, the provision of indemnity; and 
  
 (e) during such 60-day period the Holders of a majority in principal amount at maturity of the then outstanding Notes do not give the
Trustee a direction inconsistent with the request. 
  
 A Holder of
a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. 
  
 SECTION 6.07. Rights of Holders of Notes to Receive Payment 
  
 Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and Additional Interest,
if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not
be impaired or affected without the consent of such Holder. 
  
 SECTION 6.08.
Collection Suit by Trustee 
  
 If an Event of Default
specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of principal of, premium and Additional Interest,
if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and 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. 
  
 SECTION 6.09. Trustee May File Proofs of Claim 
  
 The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to any Issuer (or any other obligor upon the Notes), its creditors or its property and shall be
entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian 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 to 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 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and
other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of 

  

 57 








 
reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding. 
  
 SECTION 6.10. Priorities

  
 If the Trustee collects any money pursuant to this
Article, it shall pay out the money in the following order: 
  
 First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs
and expenses of collection; 
  
 Second: to
Holders of Notes for amounts due and unpaid on the Notes for principal, premium and Additional Interest, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal,
premium and Additional Interest, if any and interest, respectively; and 
  
 Third: to the Issuers or to such party as a court of competent jurisdiction shall direct. 
  
 The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 
  
 SECTION 6.11. 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 or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion
may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount at maturity of the then outstanding Notes.

 TRUSTEE 
  
 SECTION 7.01. Duties of Trustee 
  
 (a) If 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 its exercise, as a

 SECTION 7.03. Individual Rights of Trustee 
  
 The Trustee in its individual or any other capacity may become the owner or
pledgee of Notes and may otherwise deal with the Issuers or any Affiliate of the Issuers with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such
conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. 
  
 SECTION 7.04. Trustee’s Disclaimer

connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. 
  
 SECTION 7.05. Notice of Defaults 
  
 If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest or Additional Interest on any Note, the Trustee may withhold the notice if and

loss, liability or expense may be attributable to its negligence or bad faith. The Trustee shall notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers shall not relieve the Issuers
of their obligations hereunder. The Issuers shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Issuers shall pay the reasonable fees and expenses of such counsel. The Issuers need not
pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
  
 SECTION 8.01. Option to Effect Legal Defeasance or Covenant Defeasance

cancellation or (ii) all outstanding Notes have become due and payable, whether at maturity or as a result of the mailing of a notice of redemption pursuant to Article 3 hereof and the Issuers irrevocably deposit with the Trustee funds sufficient to
pay at maturity or upon redemption all outstanding Notes, including interest thereon to maturity or such redemption date (other than Notes replaced pursuant to Section 2.07), and if in either case the Issuers pay all other sums payable hereunder by
the Issuers, then this Indenture shall, subject to the proviso set forth in Section 8.02, cease to be of further effect. The Issuers may, at the option of their Boards of Directors evidenced by a resolution set forth in an Officers’
Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof applied to all outstanding Notes upon compliance with the conditions set forth below in this Article Eight. 
  
 SECTION 8.02. Legal Defeasance and Discharge 
  
 Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuers shall,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from all of their obligations with respect to all outstanding Notes and this Indenture on the date the conditions set forth below are
satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuers shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter
be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Notes and this Indenture (and
the Trustee, on demand of and at the expense of the Issuers, shall execute proper instruments acknowledging the same); provided that the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the
rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest and Additional

8.03 hereof. 
  
 SECTION 8.03. Covenant Defeasance 
  
 Upon the Issuers’ exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Issuers shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from their obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12,

not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all
other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuers may omit to comply with and
shall have no liability in 

  

 63 








 
respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as
specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of
the conditions set forth in Section 8.04 hereof, Sections 6.01(d) through 6.01(f) hereof shall not constitute Events of Default. 
  
 SECTION 8.04. Conditions to Legal or Covenant Defeasance 
  
 The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Notes: 
  
 In order to exercise either Legal Defeasance or Covenant Defeasance: 
  
 (a) the Issuers must irrevocably deposit with the Trustee,
in trust, for the benefit of the Holders, cash in United States dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of, premium, if any, and interest and Additional Interest, if any, on the outstanding Notes on their Stated Maturity or on the applicable redemption date, as the case may be, and the Issuers must specify whether the
Notes are being defeased to maturity or to a particular redemption date; 
  
 (b) in the case of an election under Section 8.02 hereof, the Issuers shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that (A) the Issuers
have received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such
Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 
  
 (c) in the case of an election under Section 8.03 hereof, the Issuers shall have delivered to the Trustee an Opinion of Counsel in the
United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
  
 (d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of
Default resulting from the incurrence of Indebtedness all or a portion of the proceeds of which will be used to defease the Notes pursuant to this Article Eight concurrently with such incurrence) or insofar as Sections 6.01(g) or 6.01(h) hereof is
concerned, at any time in the period ending on the 91st day after the date of deposit; 
  
 (e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than this Indenture) to which the Issuers or any of the Restricted Subsidiaries is a party or by which the Issuers or any of the Restricted Subsidiaries is bound; 
  

 64 








 (f) the Issuers shall have delivered to the Trustee an Opinion of Counsel (which may be
subject to customary exceptions) to the effect that on the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights
generally; 
  
 (g) each of the Issuers shall have
delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuers with the intent of preferring the Holders over any other creditors of the Issuers or with the intent of defeating, hindering, delaying or
defrauding any other creditors of the Issuers or others; and 
  
 (h) each of the Issuers shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the
Covenant Defeasance have been complied with. 
  
 SECTION 8.05. Deposited
Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions 
  
 Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section
8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly
or through any Paying Agent (including an Issuer acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, interest and Additional Interest,
if any, but such money need not be segregated from other funds except to the extent required by law. 
  
 The Issuers shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 
  
 Anything in this Article Eight to the contrary notwithstanding, the Trustee
shall deliver or pay to the Issuers from time to time upon the request of the Issuers any money or non-callable Government Securities held by them as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited
to effect an equivalent Legal Defeasance or Covenant Defeasance. 
  
 SECTION
8.06. Repayment to Issuers 
  
 Any money deposited
with the Trustee or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of, premium, if any, or interest on any Note 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 Issuers on its request or (if then held by the Issuers) shall be discharged from such trust; and the Holder of such Note shall thereafter, as a secured creditor, look only to the Issuers for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers as trustee thereof, shall thereupon cease. 
  

 65 








 SECTION 8.07. Reinstatement 
  
 If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in
accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers’ obligations under
this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section
8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Issuers have made any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Issuers shall be subrogated to the
rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 
  
 ARTICLE 9. 
  
 AMENDMENT, SUPPLEMENT AND WAIVER 
  
 SECTION 9.01. Without
Consent of Holders of Notes 
  
 Notwithstanding Section
9.02 of this Indenture, the Issuers and the Trustee may amend or supplement this Indenture or the Notes without the consent of any Holder of a Note: 
  
 (a) to cure any ambiguity, defect or inconsistency; 
  
 (b) to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the
provisions of Article 2 hereof (including the related definitions) in a manner that does not materially adversely affect any Holder; 
  
 (c) to provide for the assumption of any Issuer’s obligations to the Holders of the Notes by a successor to such Issuer in accordance
with the provisions of this Indenture or pursuant to Article 5 hereof; 
  
 (d) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture; 
  
 (e) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect
the legal rights hereunder of any Holder of the Note; or 
  
 (f) to comply with the requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA. 
  

Upon the request of each of the Issuers accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Issuers in the execution of any amended or supplemental Indenture authorized or permitted by the terms of this
Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities
under this Indenture or otherwise. 
  

 66 








 SECTION 9.02. With Consent of Holders of Notes 
  
 Except as provided below in this Section 9.02, the Issuers and the Trustee
may amend or supplement this Indenture (including Section 3.09, 4.10 and 4.15 hereto) and the Notes may be amended or supplemented with the consent of the Holders of at least a majority of the aggregate principal amount at maturity of the Notes then
outstanding voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other
than a Default or Event of Default in the payment of the principal of, premium, if any, or interest or Additional Interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any
provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority of the aggregate principal amount at maturity of the then outstanding Notes voting as a single class (including consents obtained in connection with
a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02. 
  
 Upon the request of the Issuers accompanied by a resolution of the Board of
Directors of each Issuer authorizing the execution of any such amended or supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by
the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Issuers in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture directly affects the Trustee’s own
rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture. 
  
 It shall not be necessary for the consent of the Holders of Notes under this
Section 9.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. 
  
 After an amendment, supplement or waiver under this Section becomes effective, the Issuers shall mail to the Holders of Notes affected thereby a notice
briefly describing the amendment, supplement or waiver. Any failure of the Issuers to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver.
Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount at maturity of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Issuers with any provision of
this Indenture or the Notes. However, without the consent of each Holder affected, an amendment or waiver under this Section 9.02 may not (with respect to any Notes held by a nonconsenting Holder): 
  
 (a) reduce the principal amount at maturity of Notes whose
Holders must consent to an amendment, supplement or waiver; 
  
 (b) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes except as provided above with respect to Sections 3.09, 4.10 and
4.15 hereof; 
  
 (c) reduce the rate of or change
the time for payment of interest or Additional Interest, including default interest, on any Note; 
  
 (d) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest or Additional Interest on the Notes
(except a rescission of acceleration of the 

  

 67 








 
Notes by the Holders of at least a majority in aggregate principal amount at maturity of the then outstanding Notes and a waiver of the payment default that
resulted from such acceleration); 
  
 (e) make
any Note payable in money other than that stated in the Notes; 
  
 (f) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, premium, if any, or interest or Additional Interest
on the Notes; 
  
 (g) change the ranking of the
Notes; or 
  
 (h) make any change in Section 6.04
or 6.07 hereof or in the foregoing amendment and waiver provisions. 
  
 SECTION
9.03. Compliance with Trust Indenture Act 
  
 Every
amendment or supplement to this Indenture or the Notes shall be set forth in a amended or supplemental Indenture that complies with the TIA as then in effect. 
  

SECTION 9.04. Revocation and Effect of Consents 
  
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may
revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder. 
  
 SECTION 9.05. Notation on or Exchange of
Notes 
  
 The Trustee may place an appropriate notation
about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuers in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver. 
  
 Failure to make the appropriate notation
or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. 
  
 SECTION 9.06. Trustee to Sign Amendments, etc 
  
 The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article Nine if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the
Trustee. Neither of the Issuers may sign an amendment or supplemental Indenture until its Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.01
hereof) shall be fully protected in relying upon, in addition to the documents required by Section 10.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.
