multiple thereof, the denominations in which the Securities of the Series shall be issuable; 
  

 6

if in fully registered form, whether the Securities will be issuable as Global Securities); 
  
 (12) if other than the principal amount thereof, the portion of the principal amount of the Securities of the Series that shall be payable
upon declaration of acceleration of the maturity thereof pursuant to Section 6.02; 
  
 (13) the currency of denomination of the Securities of the Series, which may be Dollars or any Foreign Currency, including, but not
limited to, the ECU, and if such currency of denomination is a composite currency other than the ECU, the agency or organization, if any, responsible for overseeing such composite currency; 
  
 (14) the designation of the currency, currencies or currency
units in which payment of the principal of and interest, if any, on the Securities of the Series will be made; 
  
 (15) if payments of principal of or interest, if any, on the Securities of the Series are to be made in one or more currencies or currency

 (16) the manner in which the amounts of payment of principal of or interest, if any, on the Securities of

 (19) any
addition to or change in the covenants set forth in Articles 4 or 5 which applies to Securities of the Series;

 (21) any depositories, interest rate calculation agents, exchange rate calculation agents or other agents with respect to Securities of
such Series if other than those appointed herein. All Securities of any one Series need not be issued at the same time and may be issued from time to time, consistent with the terms of this Indenture, if so provided by or pursuant to the Board
Resolution, supplemental indenture or Officers’ Certificate referred to above, and the authorized principal amount of any Series may not be increased to provide for issuances of additional Securities of such Series, unless otherwise provided in
such Board Resolution, supplemental indenture or Officers’ Certificate. 
  

 7 








 Section 2.03. Execution and Authentication. 
  
 Two Officers shall sign the Securities for the Company by manual or
facsimile signature. 
  
 If an Officer whose signature is on a
Security no longer holds that office at the time the Security is authenticated, the Security shall nevertheless be valid. 
  
 A Security shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. The signature shall be conclusive
evidence that the Security has been authenticated under this Indenture. 
  
 The Trustee shall at any time, and from time to time, authenticate Securities for original issue in the principal amount provided in the Board Resolution, supplemental indenture hereto or Officers’ Certificate, upon receipt by the
Trustee of a Company Order. Such Company Order may authorize authentication and delivery pursuant to oral or electronic instructions from the Company or its duly authorized agent or agents, which oral instructions shall be promptly confirmed in
writing. Each Security shall be dated the date of its authentication unless otherwise provided by a Board Resolution, a supplemental indenture hereto or an Officers’ Certificate. 
  
 The aggregate principal amount of Securities of any Series outstanding at any time may not exceed any limit upon the maximum
principal amount for such Series set forth in the Board Resolution, supplemental indenture hereto or Officers’ Certificate delivered pursuant to Section 2.02, except as provided in Section 2.08. 
  
 Prior to the issuance of Securities of any Series, the Trustee shall have
received and (subject to Section 7.02) shall be fully protected in relying on: (a) the Board Resolution, supplemental indenture hereto or Officers’ Certificate establishing the form of the Securities of that Series or of Securities within that
Series and the terms of the Securities of that Series or of Securities within that Series, (b) an Officers’ Certificate complying with Section 10.04, and (c) an Opinion of Counsel complying with Section 10.04. 
  
 The Trustee shall have the right to decline to authenticate and deliver any
Securities of such Series: (a) if the Trustee, being advised by counsel, determines that such action may not lawfully be taken; or (b) if the Trustee in good faith by its board of directors or trustees, executive committee or a trust committee of
directors and/or vice-presidents shall determine that such action would expose the Trustee to personal liability to Holders of any then outstanding Series of Securities. 
  
 The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating
agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the
Company or an Affiliate. 
  
 Section 2.04. Registrar and Paying
Agent. 
  
 The Company shall maintain, with respect to each
Series of Securities, at the place or places specified with respect to such Series pursuant to Section 2.02, an office or agency where Securities of such Series may be presented or surrendered for payment (“Paying Agent”), where Securities
of such Series may be surrendered for registration of transfer or exchange (“Registrar”) and where notices and demands to or upon the Company in respect of the Securities of such Series and this Indenture may be served (“Service
Agent”). The Registrar shall keep a register with respect to each Series of Securities and to their transfer and exchange. The Company will give prompt written notice to the Trustee of the name and address, and any change in the name or
address, of each Registrar, Paying Agent or Service Agent. If at any time the Company shall fail to maintain any such required Registrar, Paying Agent or Service Agent or shall fail to furnish the Trustee with the name and address thereof, such
presentations, surrenders, notices and demands may be made or served at the 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.

  

 8 








 The Company may also from time to time designate one or more co-registrars, additional paying agents or
additional service agents and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligations to maintain a Registrar, Paying Agent and Service
Agent in each place so specified pursuant to Section 2.02 for Securities of any Series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the name or address of
any such co-registrar, additional paying agent or additional service agent. The term “Registrar” includes any co-registrar; the term “Paying Agent” includes any additional paying agent; and the term “Service Agent”
includes any additional service agent. 
  
 The Company hereby
appoints the Trustee the initial Registrar, Paying Agent and Service Agent for each Series unless another Registrar, Paying Agent or Service Agent, as the case may be, is appointed prior to the time Securities of that Series are first issued.

  
 Section 2.05. Paying Agent to Hold Money in Trust.

  
 The Company 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 Securityholders of any Series of Securities, or the Trustee, all money held by the Paying Agent for the payment of principal of or interest on the Series of
Securities, and will notify the Trustee of any default by the Company 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 Company at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as
Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of Securityholders of any Series of Securities all money held by it as Paying Agent. 
  
 Section 2.06. Securityholder Lists. 
  
 The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the
names and addresses of Securityholders of each Series of Securities and shall otherwise comply with TIA (S) 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least ten days before each interest payment date and
at such other times as the Trustee may request in writing a list, in such form and as of such date as the Trustee may reasonably require, of the names and addresses of Securityholders of each Series of Securities. 
  
 Section 2.07. Transfer and Exchange. 
  
 Where Securities of a Series are presented to the Registrar or a co-
registrar with a request to register a transfer or to exchange them for an equal principal amount of Securities of the same Series, the Registrar shall register the transfer or make the exchange if its requirements for such transactions are met. To
permit registrations of transfers and exchanges, the Trustee shall authenticate Securities at the Registrar’s request. No service charge shall be made for any registration of transfer or exchange (except as otherwise expressly permitted
herein), but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer tax or similar governmental charge payable upon exchanges
pursuant to Sections 2.11, 3.06 or 9.05). 
  

 9 








 Neither the Company nor the Registrar shall be required (a) to issue, register the transfer of, or
exchange Securities of any Series for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of Securities of that Series selected for redemption and ending at the close of business
on the day of such mailing, or (b) to register the transfer of or exchange Securities of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such Securities selected, called or being called for
redemption in part. 
  
 Section 2.08. 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 the same Series and 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 either 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 make available for delivery, in lieu of any such destroyed, lost or
stolen Security, a new Security of the same Series and 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 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. 
  
 Every new Security of any
Series 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 of that Series 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 2.09. Outstanding Securities. 
  
 The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest on a Global Security
effected by the Trustee in accordance with the provisions hereof and those described in this Section as not outstanding. 
  
 If a Security is replaced pursuant to Section 2.08, it ceases to be outstanding until the Trustee receives proof satisfactory to it that the replaced
Security is held by a bona fide purchaser. 
  
 If the Paying Agent
(other than the Company, a Subsidiary or an Affiliate of any thereof) holds on the Maturity of Securities of a Series money sufficient to pay such Securities payable on that date, then on and after that date such Securities of the Series cease to be
outstanding and interest on them ceases to accrue. 
  

 10 








 A Security does not cease to be outstanding because the Company or an Affiliate holds the Security.

  
 In determining whether the Holders of the requisite principal
amount of outstanding Securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder, the principal amount of a Discount Security that shall be deemed to be outstanding for such purposes shall be the amount
of the principal thereof that would be due and payable as of the date of such determination upon a declaration of acceleration of the Maturity thereof pursuant to Section 6.02. 
  
 Section 2.10. Treasury Securities. 
  
 In determining whether the Holders of the required principal amount of Securities of a Series have concurred in any request,
demand, authorization, direction, notice, consent or waiver Securities of a Series owned by the Company or an Affiliate shall be disregarded, except that for the purposes of determining whether the Trustee shall be protected in relying on any such
request, demand, authorization, direction, notice, consent or waiver only Securities of a Series that the Trustee knows are so owned shall be so disregarded. 
  
 Section 2.11. Temporary Securities. 
  
 Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities upon a Company Order.
Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee upon
request shall authenticate definitive Securities of the same Series and date of maturity in exchange for temporary Securities. Until so exchanged, temporary securities shall have the same rights under this Indenture as the definitive Securities.

  
 Section 2.12. Cancellation. 
  
 The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for transfer, exchange, payment,
replacement or cancellation and shall destroy such canceled Securities (subject to the record retention requirement of the Exchange Act) and deliver a certificate of such destruction to the Company, unless the Company otherwise directs. The Company
may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation. 
  
 Section 2.13. Defaulted Interest. 
  
 If the Company defaults in a payment of interest on a Series of Securities, it shall pay the defaulted interest, plus, to the extent permitted by law, any
interest payable on the defaulted interest, to the persons who are Securityholders of the Series on a subsequent special record date. The Company shall fix the record date and payment date. At least 30 days before the record date, the Company shall
mail to the Trustee and to each Securityholder of the Series a notice that states the record date, the payment date and the amount of interest to be paid. The Company may pay defaulted interest in any other lawful manner. 
  

 11 








 Section 2.15. Global Securities. 
  
 (1) Terms of Securities. A Board Resolution, a supplemental indenture hereto or an Officers’
Certificate shall establish whether the Securities of a Series shall be issued in whole or in part in the form of one or more Global Securities and the Depository for such Global Security or Securities. 
  
 (2) Transfer and Exchange. Notwithstanding any
provisions to the contrary contained in Section 2.07 of the Indenture and in addition thereto, any Global Security shall be exchangeable pursuant to Section 2.07 of the Indenture for Securities registered in the names of Holders other than the
Depository for such Security or its nominee only if (i) such Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security or if at any time such Depository ceases to be a clearing agency
registered under the Exchange Act, and, in either case, the Company fails to appoint a successor Depository within 90 days of such event, (ii) the Company executes and delivers to the Trustee an Officers’ Certificate to the effect that such
Global Security shall be so exchangeable or (iii) an Event of Default with respect to the Securities represented by such Global Security shall have happened and be continuing. Any Global Security that is exchangeable pursuant to the preceding
sentence shall be exchangeable for Securities registered in such names as the Depository shall direct in writing in an aggregate principal amount equal to the principal amount of the Global Security with like tenor and terms. 
  
 Except as provided in this Section 2.14(2) a Global Security may not be
transferred except as a whole by the Depository with respect to such Global Security to a nominee of such Depository, by a nominee of such Depository to such Depository or another nominee of such Depository or by the Depository or any such nominee
to a successor Depository or a nominee of such a successor Depository. 
  
 (3) Legend. Any Global Security issued hereunder shall bear a legend in substantially the following form: 
  
 “THIS GLOBAL SECURITY IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS SECURITY) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF
THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.06 OF THE INDENTURE, (II) THIS GLOBAL SECURITY MAY BE
EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.07 OF THE INDENTURE, (III) THIS GLOBAL SECURITY MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.12 OF THE INDENTURE AND (IV) THIS GLOBAL SECURITY MAY BE TRANSFERRED TO A
SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF CROWN CASTLE INTERNATIONAL CORP.” 
  
 (4) Acts of Holders. The Depository, as a Holder, may appoint agents and otherwise authorize participants to give or take any
request, demand, authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under the Indenture. 
  
 (5) Payments. Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by Section 2.02,
payment of the principal of and interest, if any, on any Global Security shall be made to the Holder thereof. 
  

 12 








 (6) Consents, Declaration and Directions. Except as provided in Section 2.14(5),
the Company, the Trustee and any Agent shall treat a person as the Holder of such principal amount of outstanding Securities of such Series represented by a Global Security as shall be specified in a written statement of the Depositary with respect
to such Global Security, for purposes of obtaining any consents, declarations, waivers or directions required to be given by the Holders pursuant to this Indenture. 
  
 Section 2.16. CUSIP Numbers. 
  
 The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee
shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided 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 and that reliance may be placed only on the other elements of identification printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. 

 
 ARTICLE 3 
  
 REDEMPTION AND PREPAYMENT 
  
 Section 3.01. Notices to Trustee. 
  
 The Company may, with respect to any Series of Securities, reserve the right
to redeem and pay the Series of Securities or may covenant to redeem and pay the Series of Securities or any part thereof prior to the Stated Maturity thereof at such time and on such terms as provided for in such Securities. If a Series of
Securities is redeemable and the Company wants or is obligated to redeem prior to the Stated Maturity thereof all or part of the Series of Securities pursuant to the terms of such Securities, it shall notify the Trustee of the redemption date and
the principal amount of Series of Securities to be redeemed. The Company shall give the notice at least 30 but no more that 60 days before the redemption date (or such shorter notice as may be acceptable to the Trustee). 
  
 Section 3.02. Selection of Securities to Be Redeemed. 
  
 Unless otherwise indicated for a particular Series by a Board Resolution, a
supplemental indenture or an Officer’s Certificate, if less than all of the Securities are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select the Securities to be redeemed as follows: 
  
 (1) if the Securities are listed on any national securities
exchange, in compliance with the requirements of the principal national securities exchange, if any, on which the Securities are listed; or 
  
 (2) if the Securities are not listed on any national securities exchange, on a pro rata basis, by lot or by such other method as the
Trustee shall deem fair and appropriate. 
  
 No Securities of
$1,000 of principal amount or less will be redeemed in part. Except as provided in the preceding sentence, provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption.
Notices of redemption will be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Securities to be redeemed at its registered address. Notices of redemption may not be conditional.

  

 13 








 If any Security is to be redeemed in part only, the notice of redemption that relates to such Security
shall state the portion of the principal amount of that Security to be redeemed. A new Security in principal amount equal to the unredeemed portion of the original Security presented for redemption will be issued in the name of the Holder thereof
upon cancellation of the original Security. Securities called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue or accrete on Securities or portions of them called for redemption.

  
 Section 3.03. Notice of Redemption. 
  
 Unless otherwise indicated for a particular Series by a Board Resolution, a
supplemental indenture or an Officers’ Certificate, at least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Securities
are to be redeemed at its registered address. 
  
 The notice shall
identify the Securities to be redeemed and shall state: 
  
 (1) the redemption date; 
  
 (2) the redemption price; 
  
 (3) if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the redemption date upon surrender of such Security, a new Security or Securities in
principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Security; 
  
 (4) the name and address of the Paying Agent; 
  
 (5) that Securities called for redemption must be surrendered to the Paying Agent to collect the redemption price; 
  
 (6) that, unless the Company defaults in making such
redemption payment, interest on Securities called for redemption ceases to accrue on and after the redemption date; 
  
 (7) the paragraph of the Securities and/or provision of an indenture pursuant to which the Securities called for redemption are being
redeemed; and 
  
 (8) 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 Securities. 
  
 At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided, however, that the
Company 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, Securities called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional. 
  

 14 








 Section 3.05. Deposit of Redemption Price. 
  
 One Business Day prior to the redemption date, the Company shall deposit
with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest on all Securities to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited
with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Securities to be redeemed. 
  
 If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall
cease to accrue on the Securities or the portions of Securities called for redemption. If a Security 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 Security was registered at the close of business on such record date. If any Security called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company 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
Securities. 
  
 Section 3.06. Securities Redeemed in Part.

  
 Upon surrender of a Security that is redeemed in part, the
Company shall issue and, upon the Company’s written request, the Trustee shall authenticate for the Holder at the expense of the Company a new Security equal in principal amount to the unredeemed portion of the Security surrendered. 

 
 ARTICLE 4

the annual information only, a report thereon by the Company’s certified independent accountants; and 

  
 (2) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports, in
each case within the time periods specified in the Company’s rules and regulations. 
  
 In addition, whether or not required by the rules and regulations of the SEC, the Company shall file a copy of all such information and reports with the SEC for public availability within the time periods specified in
the SEC’s rules and regulations (unless the SEC will not accept such a filing) and make such information available to securities analysts and prospective investors upon request. The Company shall at all times comply with TIA (S) 314(a).

 (1) The Company shall deliver to the Trustee, within 90 days
after the end of each fiscal year, an Officers’ Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, as modified or supplemented by an Officer’s Certificate, a Board Resolution or a supplemental indenture, and further stating, as
to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture, as modified or supplemented by an Officer’s
Certificate, a Board Resolution or a supplemental indenture, and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture, as modified or supplemented by an Officer’s Certificate, a
Board Resolution or a supplemental indenture, (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to
take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on the Securities is prohibited or if such event
has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto. 
  
 (2) So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the year-end
financial statements delivered pursuant to Section 4.03(1) above shall be accompanied by a written statement of the Company’s independent public accountants (who shall be a firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to their attention that would lead them to believe that the Company has violated any provisions of Article 4 or Article 5 hereof or, if any such violation has occurred,
specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation. 
  

 16 








 (3) The Company shall, so long as any of the Securities are outstanding, deliver to the
Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto.

  
 Section 4.04. Taxes. 
  
 The Company shall pay, and shall cause each of its Subsidiaries to pay,
prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the
Holders of the Securities. 
  
 Section 4.05. Stay, Extension
and Usury Laws. 
  
 The Company covenants (to the extent that
it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect
the covenants or the performance of this Indenture, as modified or supplemented by an Officer’s Certificate, a Board Resolution or a supplemental indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as
though no such law has been enacted.

the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Securities.

exercise every right and power of the Company under this Indenture, as modified or supplemented by an Officer’s Certificate, a Board Resolution or a supplemental indenture with the same effect as if such successor Person had been named as the

 ARTICLE 6

  
 DEFAULTS AND REMEDIES 
  
 Section 6.01. Events of Default. 
  
 Unless otherwise indicated for a particular Series by a Board Resolution, a
supplemental indenture, or an Officer’s Certificate, each of the following constitutes an Event of Default: 
  
 (1) default for 30 days in the payment when due of interest on the Securities; 
  
 (2) default in payment when due of the principal of or
premium, if any, on the Securities; 
  
 (3)
failure by the Company or any of its Subsidiaries to comply with the provisions described under Article 5 hereof or failure by CCIC to consummate a Change of Control Offer or Asset Sale Offer in accordance with the provisions of this Indenture, as
modified or supplemented by an Officer’s Certificate, a Board Resolution or a supplemental indenture; 
  
 (4) failure by the Company or any of its Subsidiaries for 30 days after notice by the Trustee or the Holders of at least 25% in the
aggregate principal amount of the Securities then outstanding, voting as a single class, to comply with any of its other agreements in the Indenture or the Securities; 
  
 (5) default under any mortgage, indenture or instrument under which there may be issued or by which there
may be secured or evidenced any Indebtedness (as defined in the Board Resolution, a supplemental indenture, or an Officer’s Certificate for a particular Series) for money borrowed by the Company or any of its Significant Subsidiaries (as
defined in the Board Resolution, a supplemental indenture, or an Officer’s Certificate for a particular Series) (or the payment of which is guaranteed by the Company or any of its Significant Subsidiaries) whether such Indebtedness or guarantee
now exists, or is created after the date of this Indenture, which default: 
  

 19 









	 	(a)	 	is caused by a failure to pay principal of or premium, if any, or interest on the Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date
of the default (a “Payment Default”); or 

  

	 	(b)	 	results in the acceleration of the Indebtedness prior to its express maturity and, in each case, the principal amount of any 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 $20.0 million or more; 

  
 (6) failure by the Company or any of its Significant Subsidiaries to pay final judgments aggregating in
excess of $20.0 million, which judgments are not paid, discharged or stayed for a period of 60 days; or 
  
 (7) the Company or any of its Restricted Subsidiaries (as defined in an Officer’s Certificate, a Board Resolution, or a supplemental
indenture) pursuant to or within the meaning of Bankruptcy Law: 
  

	 	(a)	 	commences a voluntary case, 

  

	 	(b)	 	consents to the entry of an order for relief against it in an involuntary case, 

  

	 	(c)	 	consents to the appointment of a Custodian of it or for all or substantially all of its property, 

  

	 	(d)	 	makes a general assignment for the benefit of its creditors, or 

  

	 	(e)	 	generally is not paying its debts as they become due; or 

  

	 	(8)	 	a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

  

	 	(a)	 	is for relief against the Company or any of its Restricted Subsidiaries in an involuntary case; 

  

	 	(b)	 	appoints a Custodian of the Company or any of its Restricted Subsidiaries or for all or substantially all of the property of the Company or any of its Restricted Subsidiaries; or


  

	 	(c)	 	orders the liquidation of the Company or any of its Restricted Subsidiaries; and the order or decree remains unstayed and in effect for 60 consecutive days.


  
 Section 6.02. Acceleration. 

 
 If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Securities may declare all the Securities to be due and payable immediately. Upon any such declaration, the principal of, and accrued and unpaid interest if any, on such Securities
shall become due and payable immediately. Notwithstanding the foregoing, if an Event of Default specified in clause (7) or (8) of Section 6.01 hereof occurs with respect to the Company or any of its Restricted Subsidiaries, all outstanding
Securities shall be due and payable immediately without further action or notice. The Holders of a majority in aggregate principal amount of the then outstanding 
  

 20 








 Securities by written notice to the Trustee may on behalf of all of the Holders rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or
waived. 
  
 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 of, premium, if any, and interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. 
  
 The Trustee may maintain a proceeding even if it does not possess any of the
Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Security 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 Securities by notice to the Trustee may on behalf of the Holders
of all of the Securities 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 on, the Securities (including in
connection with an offer to purchase) (provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Securities 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 of the then outstanding Securities 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 Securities or that may involve the Trustee in personal liability.

  
 Section 6.06. Limitation on Suits. 
  
 A Holder of a Security may pursue a remedy with respect to this Indenture or
the Securities only if: 
  
 (1) the Holder of a
Security gives to the Trustee written notice of a continuing Event of Default; 
  
 (2) the Holders of at least 25% in principal amount of the then outstanding Securities make a written request to the Trustee to pursue the
remedy; 
  
 (3) such Holder of a Security or
Holders of Securities offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; 
  

 21 








 (4) 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 
  
 (5) during such 60-day period the Holders of a majority in principal amount of the then outstanding Securities do not give the Trustee a direction inconsistent with the request. 
  
 A Holder of a Security may not use this Indenture to prejudice the rights of
another Holder of a Security or to obtain a preference or priority over another Holder of a Security. 
  
 Section 6.07. Rights of Holders of Securities to Receive Payment. 
  
 Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of principal
of, premium, if any, and interest on the Security, on or after the respective due dates expressed in the Security (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 Company for the whole
amount of principal of, premium, if any, and interest remaining unpaid on the Securities 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 Securities allowed in any judicial proceedings relative to the Company (or any other
obligor upon the Securities), 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 reorganization, arrangement, adjustment or composition affecting the Securities 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. 
  

 22 








 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 Securities for amounts due and unpaid on the Securities for principal, premium, if any, and interest,
ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal, premium, if any and interest, respectively; and 
  
 Third: to the Company 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 Securities 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 Security pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Securities. 
  
 ARTICLE 7 
  
 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 prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 
  
 (b) Except during the continuance of an Event of Default: 
  

	 	(i)	 	the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in

 23 









	 	(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. However, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.


  
 (c) The Trustee may not be relieved from
liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
  

	 	(i)	 	this paragraph does not limit the effect of paragraph (b) of this Section;

 (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 
  
 Section 7.02. Rights of Trustee. 
  
 (a) The Trustee may conclusively rely upon any document believed by it to be
genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.

be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel and the written and oral advice of such counsel or any Opinion of Counsel

from the Company shall be sufficient if signed by an Officer of the Company. 
  
 (f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the
Trustee reasonable security or indemnity against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. 
  

Section 7.03. Individual Rights of Trustee. 
  
 The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any Affiliate
of the Company 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.

direction under any provision of this Indenture, as modified or supplemented by an Officer’s Certificate, a Board Resolution or a supplemental indenture, it shall not be responsible for the use or application of any money received by any Paying
Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Securities or any other document in connection with the sale of the Securities 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 Securities 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 on any Security, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Securities.

  
 Section 7.06. Reports by Trustee to Holders of the
Securities. 
  
 Within 60 days after each May 15, beginning
with the May 15 for so long as Securities remain outstanding, the Trustee shall mail to the Holders of the Securities a brief report dated as of such reporting date that complies with TIA (S) 313(a) (but if no event described in TIA (S) 313(a) has
occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA (S) 313(b). The Trustee shall also transmit by mail all reports as required by TIA (S) 313(c). 
  
 A copy of each report at the time of its mailing to the Holders of Securities
shall be mailed to the Company and filed with the SEC and each stock exchange on which the Securities are listed in accordance with TIA (S) 313(d). The Company shall promptly notify the Trustee when the Securities are listed on any stock exchange.

  

 25 








 Section 7.07. Compensation and Indemnity. 
  
 The Company shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request
for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and
counsel. 
  
 The Company shall indemnify the Trustee against any
and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company
(including this Section 7.07) and defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to
the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not
relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel.
The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. 
  
 The obligations of the Company under this Section 7.07 shall survive the satisfaction and discharge of this Indenture. 
  
 To secure the Company’s payment obligations in this Section, the Trustee
shall have a Lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Securities. Such Lien shall survive the satisfaction and discharge of this
Indenture. 
  
 When the Trustee incurs expenses or renders
services after an Event of Default specified in Section 6.01(g) or (h) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of
administration under any Bankruptcy Law. 
  
 The Trustee shall
comply with the provisions of TIA (S) 313(b)(2) to the extent applicable. 
  
 Section 7.08. Replacement of Trustee.

 The Trustee may resign in writing at any time and be discharged from the
trust hereby created by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Securities may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if:

  
 (a) the Trustee fails to comply with Section 7.10 hereof;

  
 (b) the Trustee is adjudged a bankrupt or an insolvent or an
order for relief is entered with respect to the Trustee under any Bankruptcy Law; 
  

 26 








 (c) a Custodian or public officer takes charge of the Trustee or its property; or 
  
 (d) the Trustee becomes incapable of acting. 
  
 If the Trustee resigns or is removed or if a vacancy exists in the office of
Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Securities may appoint a successor
Trustee to replace the successor Trustee appointed by the Company. 
  
 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in principal amount of the then outstanding Securities may
petition any court of competent jurisdiction for the appointment of a successor Trustee. 
  
 If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10, such Holder may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee. 
  
 A
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the
rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided
all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof
shall continue for the benefit of the retiring Trustee. 
  
 Section 7.09. Successor Trustee by Merger, etc. 
  
 If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee.

Company.

Securities, 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 (1) and (2) below, and to have satisfied all its other obligations under
such Securities and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or
discharged hereunder: 
  
 (1) the rights of
Holders of outstanding Securities 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 on such Securities when
such payments are due; 
  
 (2) the Company’s
obligations with respect to such Securities under Article 2 and Section 4.02 hereof; 
  
 (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s obligations in connection therewith;
and 
  
 (4) this Article Eight. 
  
 Subject to compliance with this Article Eight, the Company may exercise its
option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. 
  
 Section 8.03. Covenant Defeasance. 
  
 Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in an Officer’s Certificate, a Board Resolution or a supplemental indenture and clause (4) of Section 5.01 hereof with respect to
the outstanding Securities on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant Defeasance”), and the Securities shall thereafter be deemed 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 Securities shall not be deemed outstanding for accounting 
  

 28 








 purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Securities, the Company may
omit to comply with and shall have no liability in 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 Securities shall be unaffected thereby. In addition, upon the Company’s 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(3) through 6.01(6) 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 Securities: 
  
 In order to exercise either Legal Defeasance or Covenant Defeasance:

  
 (1) the Company 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 on the outstanding Securities on the stated date for payment thereof or on the applicable redemption date, as the case may be; 
  
 (2) in the case of an election under Section 8.02 hereof,
the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that: 
  

	 	(a)	 	the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or 

  

	 	(b)	 	since the date of this Indenture, 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 Securities 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; 

  
 (3) in the case of an election under Section 8.03 hereof, the Company 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 Securities 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; 
  
 (4) no Default or Event of Default shall have occurred and be continuing either: 
  

	 	(a)	 	on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit); or 

  

 29 









	 	(b)	 	insofar as Sections 6.01(7) or 6.01(8) hereof are concerned, at any time in the period ending on the 91st day after the date of deposit; 

  
 (5) 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 Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its
Restricted Subsidiaries is bound; 
  
 (6) the
Company shall have delivered to the Trustee an Opinion of Counsel 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; 
  
 (7) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of
defeating, hindering, delaying or defrauding any other creditors of the Company or others; and 
  
 (8) the Company 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 Securities
shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may
determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 

 
 The Company 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 Securities. 
  
 Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it 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 Company. 
  
 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, premium, if any, or
interest on any Security and remaining 
  

 30 








 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 its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter 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 the New York Times and The Wall Street Journal (national edition), 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
notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
  
 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 Company’s obligations under this Indenture and the Securities 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 Company makes any payment of principal of, premium, if any, or interest on any Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such
Securities 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 Securities. 
  
 Notwithstanding Section 9.02 of
this Indenture, the Company and the Trustee may amend or supplement this Indenture or the Securities without the consent of any Holder of Securities: 
  
 (1) to cure any ambiguity, defect or inconsistency; 
  
 (2) to provide for uncertificated Securities in addition to or in place of certificated Securities;

  
 (3) to provide for the assumption of the
Company’s obligations to the Holders of the Securities by a successor to the Company pursuant to Article 5 hereof; 
  
 (4) to make any change that would provide any additional rights or benefits to the Holders of the Securities or that does not adversely
affect the legal rights hereunder of any Holder of Securities; 
  
 (5) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; or 
  

(6) as provided in Section 2.02 hereof. 
  

 31 








 Upon the request of the Company 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 Company 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. 
  
 Section 9.02. With Consent of Holders of Securities. 
  
 Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture and the Securities with the consent of the Holders of at least a majority in principal amount of the Securities then
outstanding, voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Securities), 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 on the Securities, except a payment default resulting from an acceleration that has been rescinded) or compliance with any
provision of this Indenture or the Securities may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Securities, voting as a single class (including consents obtained in connection with a tender offer
or exchange offer for, or purchase of, the Securities). Section 2.09 hereof shall determine which Securities are considered to be “outstanding” for purposes of this Section 9.02. 
  
 Upon the request of the Company accompanied by a resolution of its Board of
Directors 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 Securities as aforesaid, and upon receipt by the Trustee
of the documents described in Section 7.02 hereof, the Trustee shall join with the Company 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 Securities 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 Company shall mail to the Holders of Securities affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of the Company 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 of the Securities then outstanding, voting as a single class, may waive compliance in a particular instance by the Company with any provision
of this Indenture or the Securities. However, without the consent of each Holder affected, an amendment or waiver under this Section 9.02 may not (with respect to any Securities held by a non-consenting Holder): 
  
 (1) reduce the principal amount of Securities whose Holders
must consent to an amendment, supplement or waiver; 
  
 (2) reduce the principal of or change the fixed maturity of any Security or alter or waive any of the provisions with respect to the redemption of the Securities; 
  

 32 








 (3) reduce the rate of or change the time for payment of interest, including default
interest, on any Security; 
  
 (4) waive a
Default or Event of Default in the payment of principal of or premium, if any, or interest on the Securities (except a rescission of acceleration of the Securities by the Holders of at least a majority in aggregate principal amount of the then
outstanding Securities and a waiver of the payment default that resulted from such acceleration); 
  
 (5) make any Security payable in money other than that stated in the Securities; 
  
 (6) make any change in the provisions of this Indenture
relating to waivers of past Defaults or the rights of Holders of Securities to receive payments of principal of, or premium, if any, or interest on the Securities; 
  
 (7) waive a redemption payment with respect to any Security; 
  
 (8) except as provided under Article Eight hereof or in
accordance with the terms of any Security Guarantee, release any Guarantor from any of its obligations under its Security Guarantee or make any change in a Security Guarantee that would adversely affect the Holders of the Securities; or 

 
 (9) 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 Securities 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 Security is a continuing consent by the Holder of a Security
and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder of a Security or
subsequent Holder of a Security may revoke the consent as to its Security 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. Section 9.05. Notation on or Exchange of Securities. 
  
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Security thereafter authenticated. The Company in exchange
for all Securities may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Securities that reflect the amendment, supplement or waiver. 
  
 Failure to make the appropriate notation or issue a new Security shall not affect the validity and effect of such amendment,
supplement or waiver. 
  

 33 








 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. The Company may not sign an amendment or supplemental Indenture until the 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 Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.
