set forth from time to time in the money rates section of The Wall Street Journal, becomes unavailable for any reason as determined
by Bank, the “Prime Rate” shall mean the rate of interest per annum announced by Bank as its prime rate in effect at
its principal office in the State of California (such Bank announced Prime Rate not being intended to be the lowest rate of interest
charged by Bank in connection with extensions of credit to debtors).

“Revolving
Line” is an aggregate principal amount not to exceed Six Million Dollars ($6,000,000.00) outstanding at any time.

signature of the Trustee on a Note shall be conclusive evidence that the Note has been duly and validly authenticated and issued under this Indenture. 

The Trustee shall, upon a written order of the Company signed by two Officers of the Company or by an Officer and an Assistant Secretary of
the Company (the “Authentication Order”), authenticate (i) on the Issue Date $1,100,000,000 in aggregate principal amount of Notes and (ii) at any time and from time to time thereafter, Additional Notes (subject to the

Manhattan, The City of New York. The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes
any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without prior notice to any Holder. The Company shall notify the Trustee in writing of the name and
address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

 The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global

Trustee and to account for any funds disbursed by such Paying Agent. 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 the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying
Agent for the Notes.

 -39- 

 (vii) The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the

 (ix) Subject
to compliance with any applicable additional requirements contained in this Article, when a Note is presented to the Registrar with a request to register a transfer thereof or to exchange such Note for an equal principal amount of Notes of other
authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that every Note presented or surrendered for registration of transfer or exchange shall be duly endorsed or
accompanied by an assignment form and, if applicable, a transfer certificate, each in the form included in Exhibit A hereto, and in form satisfactory to the Registrar and each duly executed by the Holder thereof or its attorney duly authorized in

Trustee shall authenticate, Notes of a like aggregate principal amount at the Registrar’s request.

 SECTION 2.07 Replacement Notes.

 If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order or in accordance with a previously delivered Authentication Order, shall authenticate a replacement Note if the Company’s
and the Trustee’s requirements are met. An indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any Authenticating Agent from any loss
that any of them may suffer if a Note is replaced. The Company and the Trustee may charge for their expenses in replacing a Note. 

  
 -40- 

 Every replacement Note issued in accordance with this Section 2.07 is an additional
obligation of the Company 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. 

The Company and the Trustee may charge the Holder for their expenses in replacing a Note. In the event any such mutilated, lost, destroyed or
wrongfully taken Note has become or is about to become due and payable, the Company in its discretion may pay such Note instead of issuing a new Note in replacement thereof. 

The provisions of this Section 2.07 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, lost, destroyed or wrongfully taken Notes. 
 SECTION 2.08 Outstanding Notes. 

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled 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 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a
Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary shall not be deemed to be outstanding for purposes of Section 3.07(a) 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. 
 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 the Company, a Subsidiary 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 Treasury Notes. 
 In
determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Affiliate of the Company, 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 a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. 

SECTION 2.10 Temporary Notes. 

Until certificates representing Notes are ready for delivery, the Company 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 Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee.
Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. 

  
 -41- 

 Holders of temporary Notes shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder. 
 SECTION 2.11 Cancellation. 

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of canceled
Notes in accordance with customary practices (subject to the record retention requirement of the Exchange Act). Certification of the disposal of all canceled Notes shall be delivered to the Company from time to time upon written request. The Company
may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. 
 SECTION 2.12 Defaulted
Interest. 
 If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner
plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company shall notify the
Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date; provided that no such
special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at
the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 

SECTION 2.13 Issuance of Additional Notes. 

The Company shall be entitled, subject to its compliance with Section 4.08, to issue Additional Notes under this Indenture which shall
have identical terms as the Initial Notes issued on the Issue Date or the Exchange Notes issued in exchange for the Initial Notes, other than with respect to the date of issuance and issue price, first payment of interest and rights under a related
Registration Rights Agreement, if any. 
 With respect to any Additional Notes, the Company shall set forth in a resolution of the Board of
Directors and an Officers’ Certificate, a copy of each which shall be delivered to the Trustee, the following information: 

(a) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture; 

(b) the issue price, the issue date and the CUSIP number and corresponding ISIN of such Additional Notes; and 

(c) whether such Additional Notes shall be issued in the form of Initial Notes as set forth in Exhibit A hereto or shall be
issued in the form of Exchange Notes as set forth in Exhibit A hereto. 

  
 -42- 

 SECTION 2.14 One Class of Securities. 

The Initial Notes issued on the Issue Date, all Exchange Notes issued in exchange therefor and any Additional Notes shall be treated as a
single class for all purposes under this Indenture. 
 SECTION 2.15 CUSIP, ISIN or Other Similar Numbers. 

The Company in issuing the Notes may use “CUSIP,” “ISIN” or other similar numbers (if then generally in use), and, if so,
the Trustee shall use “CUSIP,” “ISIN” or other similar 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 Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP,” “ISIN” or other similar numbers.

in accordance with any other method the Trustee shall deem fair and appropriate, in each case in accordance with the procedures of the Depositary; provided that no Notes of $2,000 in aggregate principal amount 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. 
 The Trustee shall promptly notify the Company 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 $2,000 or whole multiples of $1,000 in excess thereof; 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 in a minimum amount of $2,000 or a multiple of $1,000 in excess thereof, 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. 

At least thirty (30) days but not more than sixty (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 of Notes to be redeemed at its registered address, except that redemption notices may be mailed more than sixty (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 this Indenture. 
 The notice shall identify the Notes
(including CUSIP Number(s)) to be redeemed and shall state: 
 (a) the redemption date; 

(b) the redemption price; 
 (c) if
any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount of that 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 in the name of the Holder thereof 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;

redemption ceases to accrue on and after the redemption date;

which the Notes called for redemption are being redeemed; 
 (h) that no representation is made as to the correctness or accuracy of the
CUSIP or ISIN number, if any, listed in such notice or printed on the Notes; and 
 (i) the amount of the Applicable Premium, if any. 

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 (unless a shorter period is acceptable to the Trustee), 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 shall

 SECTION 3.05 Deposit of Redemption Price. 

Prior to 11:00 a.m. New York City time on 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 and Additional Interest, if any, on all Notes to be redeemed on that date. Subject to applicable abandoned property laws, the Trustee or the Paying Agent shall promptly, upon request,
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 and Additional Interest on, all Notes 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 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 and Additional Interest, if any, 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 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 Notes
and in Section 4.01 hereof. 
 SECTION 3.06 Notes Redeemed in Part. 

Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon receipt of an Authentication Order, the Trustee shall

Additional Interest, if any, to, the redemption date. Notice of redemption need not set forth the Applicable Premium but only the manner of calculation of the redemption price. With respect to any such redemption, the Company shall notify the
Trustee of the Applicable Premium with respect to the Notes promptly after the calculation and the Trustee shall not be responsible for such calculation. 

(b) During the period after the date of original issuance of the Notes until September 1, 2019, the Company may, upon notice as provided
in Section 3.03 on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes originally issued at a redemption price of 104.875% of the principal amount of the Notes to be redeemed on the redemption date plus

the Company will make available such information to prospective purchasers of the Notes, in addition to providing such information to the Trustee and the Holders, in each case within fifteen (15) days after the time the Company would be
required to file such information with the SEC if it were subject to Section 13 or 15(d) of the Exchange Act. 
 In addition, to the
extent not satisfied by the foregoing, the Company agrees that, for so long as any Notes remain outstanding, it shall furnish to the holders of the Notes and to securities analysts and prospective investors, upon their request, the information
required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

 SECTION 4.04 Compliance Certificate. 

(1) The Company shall deliver to the Trustee, within ninety (90) days after the end of each fiscal year of the Company, an Officers’
Certificate, one of the signers’ of which shall be the principal executive, principal financial or principal accounting officer of the Company, 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, 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 and is not in default in the performance or observance of any of the
terms, provisions and conditions of this 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). 
 (2) The Company shall, so long as any of the Notes 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 4.05 Taxes. 
 The Company
shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent all material taxes, assessments, and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property
of the Company or any Subsidiary, except such as are contested in good faith and by appropriate proceedings or where the failure to pay or discharge the same would not have a material adverse effect on the ability of the Company to perform its
obligations under the Notes or this Indenture. 
 SECTION 4.06 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; 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. 
 SECTION 4.07 Restricted Payments. 

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly: 

 

	 	(1)	declare or pay any dividend or make any other payment or distribution (whether in cash, securities or other property) on account of the Company’s or any of its Restricted Subsidiaries’ Equity Interests
(including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Company’s or any of its Restricted
Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company or to the Company or a Restricted Subsidiary of the Company and if such
Restricted Subsidiary is not a wholly owned Subsidiary, to its other holders of Equity Interests on a pro rata basis); 

  
 -48- 

	 	(2)	purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving the Company) any Equity Interests of the Company or any direct or
indirect parent of the Company (other than (i) any such Equity Interests owned by the Company or any of its Restricted Subsidiaries or (ii) any acquisition of Equity Interests deemed to occur upon the exercise of options or restricted
stock rights if such Equity Interests represent a portion of the exercise price thereof or taxes due in connection therewith); 

  

	 	(3)	make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated to the Notes (other than intercompany Indebtedness), except a payment
of interest or a payment of principal at the Stated Maturity (or within one year of final maturity); or 

  

	 	(4)	make any Restricted Investment (all such payments and other actions set forth in these clauses (1) through (4) occurring since the Issue Date, being collectively referred to as “Restricted
Payments”), 

 unless, at the time of and after giving effect to such Restricted Payment: 

 

	 	(1)	no Default has occurred and is continuing or would occur as a consequence of the Restricted Payment; and 

  

	 	(2)	Consolidated Indebtedness to Annualized Consolidated Adjusted EBITDA Ratio would have been no greater than 9.5 to 1, calculated on a pro forma basis giving effect to such Restricted Payment and (x) removing
the financial results that would otherwise be included in such calculations in respect of any Property Disposed of after such date and on or prior to the date of making such Restricted Payment and (y) including the financial results that would
otherwise be excluded in such calculations in respect of any Property acquired after such date and on or prior to the date of making such Restricted Payment. 

Notwithstanding the foregoing, the Company may declare or pay any dividend or make any distribution on or in respect of shares of the
Company’s Capital Stock, that in each case would otherwise constitute a Restricted Payment, to holders of such Capital Stock to the extent that the declaration or payment of a dividend or making of a distribution in such amount is necessary in
order for the Company to qualify as, or maintain its status as, a real estate investment trust under Section 856 of the Code, as amended for any taxable year or to avoid entity level taxes, with such dividend to be paid or distribution to be
made as and when determined by the Company, whether during or after the end of the relevant taxable year; provided, however, that at the time of, and after giving effect to, any such dividend or distribution, no Default or Event of
Default shall have occurred and be continuing or would occur as a consequence thereof and the obligations in respect of the Notes shall not otherwise have been accelerated. 

The preceding provisions shall not prohibit: 
  

	 	(1)	the payment of any dividend or the consummation of any irrevocable redemption within sixty (60) days after the date of declaration of that dividend or giving of the redemption notice related thereto, as the case
may be, if at said date of declaration or notice such dividend or redemption payment would have complied with the provisions of this Indenture; 

  
 -49- 

	 	(2)	the making of any Restricted Payment in exchange for, or out of the net cash proceeds from the sale (other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than any Disqualified Stock);

  

	 	(3)	the defeasance, redemption, repurchase, or other acquisition of subordinated Indebtedness with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness; 

 

	 	(4)	the payment of any dividend (or, in the case of any partnership or limited liability company, any similar distribution) by a Restricted Subsidiary of the Company to the Holders of such Restricted Subsidiary’s
Equity Interests so long as, in the case of any dividend or distribution payable on or in respect of any class or series of securities issued by a Restricted Subsidiary other than a Wholly Owned Restricted Subsidiary, the Company or a Restricted
Subsidiary receives at least the lesser of (i) its pro rata share of such dividend or distribution in accordance with its Equity Interests in such class or series of securities or (ii) the amount of such dividend or distribution
provided for in the Restricted Subsidiary’s organizational documents; 

  

	 	(5)	the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any member of the Company’s (or any of its
Restricted Subsidiaries’) management pursuant to any management equity subscription agreement, restricted stock arrangement, or stock option or similar agreement in effect as of the Issue Date; provided that the aggregate price paid for
all of the repurchased, redeemed, acquired or retired Equity Interests pursuant to this clause (5) may not exceed $35.0 million in any fiscal year (with unused amounts in any fiscal year being carried over to the succeeding fiscal year);

  

	 	(6)	other Restricted Payments in an aggregate amount not to exceed $200.0 million; and 

  

	 	(7)	cash payments, in lieu of fractional shares issuable as dividends on Equity Interests of the Company or its Restricted Subsidiaries in an amount, when taken together with all other cash payments made pursuant to this
clause (7) since the issuance of the Notes, not to exceed $1.0 million. 

 For purposes of determining compliance with
this Section 4.07, in the event that a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in clauses (1) through (7) of the third paragraph of this Section 4.07 or is
permitted pursuant to the first or second paragraphs of this Section 4.07, the Company will be entitled, in its sole discretion, to classify on the date of payment, or later reclassify, in whole or in part such Restricted Payment in any manner
that complies with this Section 4.07 so long as the Restricted Payment (as so reclassified) would be permitted to be made in reliance on the applicable category as of the date of such reclassification. 

The amount of all Restricted Payments (other than cash) will be the fair market value on the date of the Restricted Payment of the assets or
securities proposed to be transferred or issued by the Company or the applicable Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any property, assets or Investments required by this Section to
be valued shall be valued by the Board of Directors of the Company or the applicable Restricted Subsidiary that is making the Restricted Payment, as the case may be, and shall be delivered to the Trustee. 

The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would not
cause a Default. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated will be deemed to be Restricted Payments at
the time of the designation. All of those outstanding Investments will be deemed to constitute Investments in 

  
 -50- 

 
an amount equal to the fair market value of the Investments at the time of such designation. Such designation will only be permitted if the Restricted Payment would be permitted at the time and
if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 
 SECTION 4.08 Incurrence of Indebtedness and Issuance of
Preferred Stock. 
 The Company 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 Company shall not issue
any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided that the Company may incur Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock and the
Company’s Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) or issue preferred stock if, in each case, the Consolidated Indebtedness to Annualized Consolidated Adjusted EBITDA Ratio at the time of incurrence of the
Indebtedness or the issuance of the 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 from such incurrence or issuance as if the same had occurred at
the beginning of the most recently ended fiscal quarter of the Company for which internal financial statements are available, would have been no greater than 9.5 to 1. 

The first paragraph of this Section 4.08 shall not prohibit the incurrence of any of the following items of Indebtedness or the issuance
of any of the following items of Disqualified Stock or preferred stock (collectively, “Permitted Debt”): 
  

	 	(1)	the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness under the Revolving Credit Facility in an aggregate principal amount (with letters of credit being deemed to have a principal amount
equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) at any time outstanding not to exceed $275.0 million; 

  

	 	(2)	the incurrence by the Company or its Restricted Subsidiaries of the Existing Indebtedness (other than Indebtedness described in clauses (1) and (4) of this paragraph); 

 

	 	(3)	the incurrence by the Company of the Indebtedness represented by the Notes to be issued on the Issue Date (other than Additional Notes) and the Exchange Notes issued in exchange therefor; 

 

	 	(4)	the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness since the Issue Date 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 Company or such Restricted Subsidiary, in an aggregate principal amount, including
all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any other Indebtedness incurred by the Company and its Restricted Subsidiaries (measured at the time of such incurrence) pursuant to this clause (4), not to exceed the
greater of (a) $75.0 million and (b) 2.0% of Consolidated Net Tangible Assets; 

  

	 	(5)	the incurrence by the Company 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 of the Company or any of its Restricted Subsidiaries or Disqualified Stock of the Company (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under the first paragraph of this Section 4.08 or
clauses (2), (3), this clause (5) or clause (9) of this paragraph; 

  
 -51- 

	 	(6)	the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that if the Company
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 that: 

(A) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the
Company or a Restricted Subsidiary; and 
 (B) any sale or other transfer of any such Indebtedness to a Person that is not either the
Company or a Restricted Subsidiary; 
 shall be deemed, in each case, to constitute an incurrence of the Indebtedness by the Company or the
Restricted Subsidiary, as the case may be; 
  

	 	(7)	the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising under Hedging Obligations, provided that such Hedging Obligations were incurred for the purpose of fixing or hedging
(i) interest rate risk, (ii) currency exchange risk or (iii) equity rate risk associated with the Company’s Class A Common Stock, and, in all cases, not for speculative purposes; 

 

	 	(8)	the guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of this Indenture;

  

	 	(9)	the incurrence or assumption of Acquired Debt of (x) the Company or a Restricted Subsidiary incurred to finance an acquisition or (y) Persons that are acquired by the Company or any Restricted Subsidiary or
merged into the Company or a Restricted Subsidiary in accordance with the terms of this Indenture; provided that, in the case of any incurrence pursuant to this clause (9), as a result of such acquisition by the Company or one of its
Restricted Subsidiaries, the Consolidated Indebtedness to Annualized Consolidated Adjusted EBITDA Ratio 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 fiscal quarter of the Company for which internal financial statements are available and (x) removing the financial results that would otherwise be included in such calculations in respect of any Property
Disposed of after such date and on or prior to the date of making such acquisition and (y) including the financial results that would otherwise be excluded in such calculations in respect of any Property acquired after such date and on or prior
to the date of making such acquisition, would have been either (i) no greater than 9.5 to 1 or (ii) less than the Consolidated Indebtedness to Annualized Consolidated Adjusted EBITDA Ratio for the same period without giving pro
forma effect to such incurrence; 

  

	 	(10)	Indebtedness owed to credit card companies which are used to pay operating expenses associated with Towers and the Services Business and letters of credit to secure such Indebtedness in an aggregate amount not exceeding
$1.0 million at any time outstanding; 

  

	 	(11)	 the incurrence by the Company or any of its Restricted Subsidiaries of any Indebtedness in respect of
(A) performance bonds, bankers’ acceptances, letters of credit, surety or appeal 

  
 -52- 

	 	
bonds or similar instruments provided by the Company or any Restricted Subsidiary in the ordinary course of business, (B) the financing of insurance premiums in the ordinary course of
business or (C) netting, overdraft protection and other arrangements arising under standard business terms of any bank at which the Company or any Restricted Subsidiary maintains an overdraft, cash pooling or other similar facility or
arrangement; 

  

	 	(12)	the incurrence by the Company or any of its Restricted Subsidiaries of any Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against
insufficient funds in the ordinary course of business, provided that such Indebtedness is extinguished within five business days of its incurrence; 

  

	 	(13)	the incurrence by the Company or any of its Restricted Subsidiaries of any Indebtedness consisting of indemnification, adjustment of purchase price, earn-out or similar obligations of the Company or any Restricted
Subsidiary, in each case incurred in connection with the acquisition or disposition of any assets, business or Person by the Company or any Restricted Subsidiary; 

 

	 	(14)	the incurrence by the Company or any of its Restricted Subsidiaries of any Guarantees in the ordinary course of business of the obligations of suppliers, customers, franchisers and licensees; 

 

	 	(15)	the incurrence by Foreign Subsidiaries which have been designated Restricted Subsidiaries of additional Indebtedness, the proceeds of which are used for ordinary course business purposes, in an aggregate principal
amount, at any time outstanding, not to exceed the greater of (x) $35.0 million and (y) 1.0% of Consolidated Net Tangible Assets; 

  

	 	(16)	the incurrence by a joint venture since the issue date of additional Indebtedness or the guarantee by the Company or another Restricted Subsidiary of the Company of the same in an aggregate principal amount, taken
together with all other Indebtedness incurred pursuant to this clause (16), at any time outstanding not to exceed $5.0 million, provided, however, that such Indebtedness incurred pursuant to this clause (16) will be subordinated in right of
payment to the Notes; and 

  

	 	(17)	the incurrence by the Company or any of its Restricted Subsidiaries since the Issue Date of additional Indebtedness and/or the issuance by the Company of Disqualified Stock in an aggregate principal amount, accreted
value or liquidation preference, as applicable, taken together with all other Indebtedness incurred pursuant to this clause (17), at any time outstanding, not to exceed $75.0 million. 

The Company shall not incur any Indebtedness that is contractually subordinated in right of payment to any other Indebtedness of the Company
unless such Indebtedness is also contractually subordinated in right of payment to the Notes on substantially identical terms; provided, however, that no Indebtedness of the Company shall be deemed to be contractually subordinated in
right of payment to any other indebtedness of the Company solely by virtue of being unsecured. 
 For purposes of determining compliance
with this Section 4.08, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (17) in the second paragraph of this Section 4.08 or is
entitled to be incurred pursuant to the first paragraph of this Section 4.08, the Company shall, in its sole discretion, classify (or later reclassify in whole or in part) such item of Indebtedness in any manner that complies with this
Section 4.08. Accrual of interest, accretion or amortization of original issue discount and the payment of interest in the form of additional Indebtedness shall not be deemed to be an incurrence of Indebtedness for purposes of this
Section 4.08. 

  
 -53- 

 In addition, for purposes of determining compliance with any U.S. dollar-denominated restriction
on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based upon the relevant currency exchange rate in effect on the date such Indebtedness was incurred,
in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would
cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been
exceeded so long as the principal amount of such Permitted Refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding the foregoing, the maximum amount of Indebtedness that the Company may
incur pursuant to this Section 4.08 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a
different currency from the Indebtedness being refinanced, shall be calculated based upon the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such
refinancing. 
 SECTION 4.09 Liens. 

The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume or suffer to exist any
Lien securing Indebtedness or trade payables on any asset or property (including Equity Interests of Restricted Subsidiaries of the Company) directly held by the Company or any Restricted Subsidiary now owned or hereafter acquired, or any income or
profits therefrom or assign or convey any right to receive income therefrom, except Permitted Liens, without providing that the Notes shall be secured equally and ratably with (or senior in priority with respect to subordinated obligations) the
obligations so secured for so long as such obligations are so secured. 
 SECTION 4.10 Dividend and Other Payment Restrictions Affecting
Subsidiaries. 
 The Company 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: 
  

	 	(1)	pay dividends or make any other distributions to the Company on its Capital Stock or with respect to any other interest or participation in, or measured by, its profits (it being understood that the priority of any
preferred stock in receiving dividends or liquidating distributions prior to the common stock shall not be deemed a restriction on the ability to make dividends on the Capital Stock); 

 

	 	(2)	pay any indebtedness owed to any Restricted Subsidiary (it being understood that the subordination of loans or advances by the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to
make loans or advances); 

  

	 	(3)	make loans or advances to any Restricted Subsidiary; or 

  

	 	(4)	transfer any of its properties or assets to any Restricted Subsidiary. 

  
 -54- 

 However, the preceding restrictions shall not apply to encumbrances or restrictions existing
under or by reason of: 
  

	 	(1)	Existing Indebtedness as in effect on the Issue Date, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that either
(i) such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions
than those contained in the applicable series of Existing Indebtedness as in effect on the Issue Date or (ii) the Company or the Restricted Subsidiary incurring the debt, as the case may be, determines that any such encumbrance or restriction
will not materially affect the Company’s ability to pay interest or principal, when due, on the Notes (which determination shall be made in the good faith judgment of the Board of Directors of the Company or the applicable Restricted Subsidiary
incurring such Indebtedness, as the case may be); 

  

	 	(2)	Indebtedness of any Restricted Subsidiary under any Credit Facility that is permitted to be incurred or outstanding pursuant to Section 4.08; provided that such Credit Facility and Indebtedness contain only
such encumbrances and restrictions on such Restricted Subsidiary’s ability to engage in the activities set forth in clauses (1) through (4) of the preceding paragraph as are, at the time such Credit Facility is entered into or
amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced, ordinary and customary for a Credit Facility of that type as determined in the good faith judgment of the Board of Directors of the Company or the
applicable Restricted Subsidiary incurring such Indebtedness, as the case may be; 

  

	 	(3)	encumbrances and restrictions applicable to any Unrestricted Subsidiary, as the same are in effect as of the date on which the Subsidiary becomes a Restricted Subsidiary, and as the same may be amended, modified,
restated, renewed, increased, supplemented, refunded, replaced or refinanced; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive, taken
as a whole, with respect to the dividend and other payment restrictions than those contained in the applicable series of Indebtedness of such Subsidiary as in effect on the date on which such Subsidiary becomes a Restricted Subsidiary;

  

	 	(4)	any Indebtedness incurred in compliance with Section 4.08 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
Company) and the Company determines that any such encumbrance or restriction will not materially affect the Company’s ability to pay interest or principal on the Notes; 

 

	 	(5)	this Indenture (including the Exchange Notes); 

  

	 	(6)	encumbrances or restrictions arising or existing by reason of applicable law or any applicable rule, regulation or order; 

  

	 	(7)	any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time that Person is acquired by the Company (except to the extent the
Indebtedness was incurred in connection with or in contemplation of the 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, the Indebtedness was permitted by the terms of this Indenture to be incurred, and provided further that any such encumbrance or restriction shall not extend to any
assets or property of the Company or any other Restricted Subsidiary other than the assets and property so acquired; 

  
 -55- 

	 	(8)	customary non-assignment provisions in leases, licenses, easements or similar arrangements entered into in the ordinary course of business; 

 

	 	(9)	purchase money obligations for property acquired in the ordinary course of business of the nature described in clause (4) in the second paragraph of Section 4.08 on the property so acquired or under Excluded
Capital Lease Obligations with respect to the property subject thereto; 

  

	 	(10)	any agreement for the sale of a Restricted Subsidiary that restricts that Restricted Subsidiary pending its sale; 

  

	 	(11)	Permitted Refinancing Indebtedness, provided that either (i) the restrictions contained in the agreements governing the Permitted Refinancing Indebtedness are not materially more restrictive, taken as a
whole, than those contained in the agreements governing the Indebtedness being refinanced or (ii) the Company determines that any such encumbrance or restriction will not materially affect the Company’s ability to pay interest or
principal, when due, on the Notes (which determination shall be made in the good faith judgment of the Board of Directors of the Company or of the applicable Restricted Subsidiary incurring the Indebtedness, as the case may be); 

 

	 	(12)	Liens permitted to be incurred pursuant to the provisions of Section 4.09 that limit the right of the debtor to transfer the assets subject to such Liens; 

 

	 	(13)	customary provisions with respect to the disposition or distribution of assets or property in joint venture agreements and other similar agreements or arrangements; 

 

	 	(14)	restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business; and 

 

	 	(15)	Indebtedness permitted to be incurred pursuant to clause (15) of the second paragraph of Section 4.08; provided, that the Company determines that any such encumbrance or restriction will not materially
affect the Company’s ability to pay interest or principal, when due, on the Notes (which determination shall be made in the good faith judgment of the Board of Directors of the Company or of the applicable Restricted Subsidiary incurring the
Indebtedness, as the case may be). 

 Each determination required to be made by the Board of Directors of the Company or the
applicable Restricted Subsidiary incurring the Indebtedness, as the case may be, pursuant to clauses (1), (2), (11) and (15) of this Section 4.10 shall be evidenced in a resolution of such Board of Directors and each such
determination shall be conclusively binding on the Company, each Restricted Subsidiary and each Holder. 
 SECTION 4.11 Transactions with
Affiliates. 
 The Company 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 of the Company involving aggregate payments of consideration in excess of $10.0 million (each of the foregoing, an “Affiliate Transaction”), unless: 

 

	 	(1)	such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such
Restricted Subsidiary with an unrelated Person; 

  
 -56- 

	 	(2)	a majority of the disinterested members of the Board of Directors of the Company or of the Restricted Subsidiary entering into the Affiliate Transaction, as the case may be, approve the transaction; and

  

	 	(3)	the Company delivers to the Trustee an Officers’ Certificate certifying that the Affiliate Transaction complies with clause (1) of this paragraph and that the Affiliate Transaction has been approved in
accordance with clause (2) of this paragraph. 

 Notwithstanding the foregoing, the following items shall not be deemed
to be Affiliate Transactions:

have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 

  

	 	(8)	any agreement as in effect as of the Issue Date, or any amendment thereto (so long as any such amendment is not disadvantageous to the Holders when taken as a whole as compared to the applicable agreement as in effect

 SECTION 4.12 Sale and Leaseback Transactions. 

The Company shall not enter into any sale and leaseback transaction with any Person in respect of any real or personal property which has been
or is to be sold or transferred by the Company to such Person or to any other Person to whom funds have been or are to be advanced by such Person on the security of such property or rental obligations of the Company; provided that the Company

	 	(1)	the Company could have: 

  

	 	(a)	incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction pursuant to Section 4.08; and

SECTION 4.13 Limitation on Issuances of Guarantees of Indebtedness. 

The Company shall not permit any Restricted Subsidiary, directly or indirectly, to Guarantee or pledge any assets to secure the payment of any
other Indebtedness of the Company unless such Subsidiary simultaneously executes and delivers a supplemental indenture to this Indenture providing for the Guarantee of the payment of the Notes by such Subsidiary, which Guarantee shall be senior to
or pari passu with such Subsidiary’s Guarantee of or pledge to secure such other Indebtedness. Notwithstanding the foregoing, any Guarantee by a 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 Subsidiary of the Company, of all of the Company’s stock in, or all or substantially all the assets of, such Subsidiary, which sale,
exchange or transfer is made in compliance with the applicable provisions of this Indenture.

franchise, or the corporate, partnership, limited liability company or other existence of any of its Restricted Subsidiaries, if the Company in good faith shall determine that the preservation thereof is no longer desirable in the conduct of the
business of the Company and its Restricted Subsidiaries, taken as a whole.

 SECTION 4.16 Change of Control Triggering Event. 

If a Change of Control Triggering Event occurs with respect to the Notes, each Holder of the Notes shall have the right to require the Company
to repurchase all or any part, equal to $2,000 or an integral multiple of $1,000, of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”). The offer price in any Change of Control Offer
shall be payable in cash and will be 101% of the aggregate principal amount of any Notes repurchased plus accrued and unpaid interest, if any, and Additional Interest, if any, on such Notes (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date), to the date of purchase (the “Change of Control Payment”). Within thirty (30) days following any Change of Control Triggering Event, unless the Company
has exercised its right to redeem all of the Notes as described in Section 3.07, the Company shall mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to
repurchase such Notes on the date specified in the notice (the “Change of Control Payment Date”). The Change of Control Payment Date shall be no earlier than thirty (30) days and no later than sixty (60) days from the date
the notice is mailed, pursuant to the procedures required by this Indenture and described in such notice. 
 On the Change of Control
Payment Date for the Notes, the Company shall, to the extent lawful: 
 (1) accept for payment all Notes or portions of the Notes properly
tendered pursuant to the Change of Control Offer; 
 (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in
respect of all Notes or portions of Notes properly tendered; and 
 (3) 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 of the Notes being purchased by the Company. 

The Paying Agent shall promptly mail to each Holder of Notes properly 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 the new Note will be in a principal
amount of $2,000 or an integral multiple of $1,000. 
 The Change of Control Triggering Event provisions described above will be applicable
whether or not any other provisions of this Indenture are applicable. The Company shall comply with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations to the extent those laws and regulations are
applicable to any Change of Control Offer. If the provisions of any of the applicable securities laws or securities regulations conflict with the provisions of this Section 4.16, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under this Section 4.16 by virtue of the compliance. 
 The
Company shall not be required to make a Change of Control Offer upon a Change of Control Triggering Event 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 Company and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer. In addition, notwithstanding the occurrence of a Change of Control Triggering
Event, the Company shall not be obligated to make a Change of Control Offer in the event it has exercised its rights to redeem all of the outstanding Notes as provided under Section 3.07. A Change of Control Offer may be made in advance of a
Change of Control and conditioned upon such Change of 

  
 -59- 

 
Control Triggering Event if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer. The provisions under this Indenture relating to the
Company’s obligation to make an offer to repurchase the Notes as a result of a Change of Control Triggering Event may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes then outstanding.

 SECTION 4.17 Asset Sales. 

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 

 

	 	(1)	the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise
disposed of; 

  

	 	(2)	fair market value is determined by the Board of Directors of the Company (or the Restricted Subsidiary, as the case may be) and evidenced by a resolution of such Board of Directors; and 

 

	 	(3)	except in the case of a Qualified Asset Exchange, at least 75% of the consideration received in such Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. 

For purposes of clause (3) above only, each of the following shall be deemed to be cash: 

 

	 	(a)	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 of the Notes) that are assumed by the transferee of any assets pursuant to a customary novation agreement that releases the Company or the Restricted Subsidiary from further liability;

  

	 	(b)	any securities, notes or other obligations received by the Company or any Restricted Subsidiary from the transferee that are converted by the Company or the Restricted Subsidiary into cash within ninety (90) days
of the applicable Asset Sale, to the extent of the cash received in that conversion; and 

  

	 	(c)	any Designated Noncash Consideration received by the Company or any of its Restricted Subsidiaries in an Asset Sale having an aggregate fair market value, taken together with all other Designated Noncash Consideration
received pursuant to this clause, not to exceed the greater of $300.0 million or 7.5% of Consolidated Net Tangible Assets in the aggregate at any time outstanding (with the fair market value of each item of Designated Noncash Consideration being
measured at the time received and without giving effect to subsequent changes in value). 

 Within 365 days after the receipt
of any Net Proceeds from an Asset Sale, the Company or the Restricted Subsidiary may apply those Net Proceeds to: 
  

	 	(1)	reduce non-subordinated Indebtedness of the Company; 

  

	 	(2)	reduce Indebtedness or Excluded Capital Lease Obligations of any of the Company’s Restricted Subsidiaries (including by way of the Company or a Restricted Subsidiary acquiring outstanding Indebtedness of any
Restricted Subsidiary to be held by the Company or a Restricted Subsidiary to redemption or maturity of such Indebtedness); 

  
 -60- 

	 	(3)	acquire all or substantially all the assets of a Permitted Business; 

  

	 	(4)	make an investment in any one or more businesses (provided that if such investment is in the form of the acquisition of Capital Stock of a Person and results in the Company or a Restricted Subsidiary owning more
than 50% of such Person, such acquisition results in such Person becoming a Restricted Subsidiary of the Company unless designated an Unrestricted Subsidiary by the Company); 

 

	 	(5)	make an investment in any one or more businesses, properties or assets that replace the properties or assets that are the subject of such Asset Sale; and/or 

 

	 	(6)	make capital expenditures or acquire other long-term assets (including long-term land use easements, ground leases and similar land rights) that are used or useful in a Permitted Business, provided that, after
giving effect thereto, the Company or its Restricted Subsidiaries is the owner of such assets or such expenditure or acquisition constitutes a Permitted Investment; 

provided that in the case of clauses (3), (4), (5) and (6) above, a binding commitment shall be treated as a permitted application of the Net
Proceeds from the date of such commitment so long as the Company or such Restricted Subsidiary enters into such commitment with the good faith expectation that such Net Proceeds shall be applied to satisfy such commitment within nine months after
the end of the 365-day period (an “Acceptable Commitment”) and, in the event any Acceptable Commitment is later cancelled, terminated or otherwise not consummated during such period for any reason, then any such unapplied Net
Proceeds shall upon such event constitute Excess Proceeds. 
 Pending the final application of any Net Proceeds, the Company may temporarily
reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture. 
 Any Net
Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraphs (whether by election or the passage of time) shall be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess
Proceeds exceeds $35.0 million, the Company shall be required to make an offer to all Holders of the Notes, and all holders of other pari passu 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 from any Asset Sale to purchase the maximum principal amount of the Notes and such other pari passu Indebtedness of the Company that may be purchased out of the Excess Proceeds
(an “Asset Sale Offer”). The offer price in any Asset Sale Offer will be payable in cash and shall be 100% of the principal amount of any Notes and pari passu Indebtedness, plus accrued and unpaid interest, if any, and
Additional Interest, if any, to the date of purchase. Each Asset Sale Offer shall be made in accordance with the procedures set forth in this Indenture and the other pari passu Indebtedness of the Company. If any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Company may use the remaining Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and the other pari passu Indebtedness of the Company
tendered into the Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of the Asset Sale Offer, the
amount of Excess Proceeds shall be reset at zero. 
 Upon the commencement of an Asset Sale Offer, the Company shall send, by first class
mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall
be made to all Holders. The notice, which shall govern the terms of the Asset Sale Offer, shall state: 
 (a) that the Asset Sale Offer is
being made pursuant to this Section 4.17 and that such Asset Sale Offer shall remain open for twenty (20) Business Days; 

  
 -61- 

 (b) the amount attributable to the Notes, the purchase price and the purchase date of the Asset
Sale (the “Purchase Date”); 
 (c) that any Note not tendered or accepted for payment shall continue to accrue interest and
Additional Interest, if any; 
 (d) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the
Asset Sale Offer shall cease to accrue interest, and Additional Interest, if any; 
 (e) that Holders electing to have a Note purchased
pursuant to any Asset Sale Offer shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, or transfer by book-entry transfer, to the Company, a Depositary,
if appointed by the Company, or a Paying Agent at the address specified in the notice at least three Business Days before the Purchase Date; 

(f) that Holders shall be entitled to withdraw their election if the Company, the depositary or the Paying Agent, as the case may be, receives,
not later than the expiration of the offer period, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election
to have such Note purchased; 
 (g) that, if the aggregate principal amount of Notes and aggregate principal amount of such other pari
passu Indebtedness tendered by Holders exceeds $35.0 million, the Company shall select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate principal amount of Notes and
the aggregate principal amount of such other pari passu Indebtedness tendered (with such adjustments as may be deemed appropriate by the Company so that only Notes and other Indebtedness in denominations of $2,000 or whole multiples of $1,000
in excess thereof, shall be purchased); and 
 (h) 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 Company shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the amount of Notes and such other pari passu Indebtedness or portions thereof tendered pursuant to the Asset Sale Offer,
or if less than $35.0 million has been tendered, all Notes and such other pari passu Indebtedness or portions thereof tendered, and shall deliver to the Trustee an Officers’ Certificate stating that such Notes and such other pari
passu Indebtedness or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 4.17. The Company, the Depositary or the Paying Agent, as the case may be, shall promptly (but in any case not
later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company shall promptly issue a new
Note, and the Trustee, upon written request from the Company shall authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be
promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Asset Sale Offer promptly after the Purchase Date. 

  
 -62- 

 If the Purchase Date is on or after an interest payment record date and on or before the related
interest payment date, any accrued and unpaid interest and Additional Interest, if any, will be paid to the Holder in whose name a note is registered at the close of business on such record date, and no other interest or Additional Interest, if any,
will be payable to Holders whose Notes are purchased pursuant to the Asset Sale Offer. 
 The Company shall comply with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations to the extent those laws and regulations are applicable to any Asset Sale Offer. If the provisions of any of the applicable securities laws or securities regulations
conflict with the provisions of this Section 4.17, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.17 by virtue of the compliance.

 SECTION 4.18 Changes in Covenants When Notes Rated Investment Grade. 

If on any date following the Issue Date: 
  

	 	(1)	the Notes are rated “Baa3” or better by Moody’s and “BBB-” or better by S&P (or, if either such entity ceases to rate the Notes for reasons outside of the control of the Company, the
equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act (registered as such pursuant to Rule 17g-1 under the Exchange
Act), selected by the Company as a replacement agency); and 

  

	 	(2)	no Default or Event of Default shall have occurred and be continuing, then, beginning on that day and subject to the provisions of the following paragraph, Sections 4.07, 4.08, 4.10, 4.11, 4.14 and 4.17 and clause
(2)(d) of Section 5.01 shall be suspended. 

 During any period that the foregoing sections have been suspended, the
Company’s Board of Directors may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to the second paragraph of the definition of “Unrestricted Subsidiary.” 

Notwithstanding the foregoing, if the rating assigned to the Notes by either such rating agency should subsequently decline to below
“Baa3” by Moody’s or “BBB-” by S&P, respectively (or if either such agency ceases to rate the Notes, the equivalent investment grade credit rating from another nationally recognized statistical rating organization), the
foregoing sections shall be reinstituted as of and from the date of such rating decline. Calculations under the reinstated Section 4.07 shall be made as if Section 4.07 had been in effect since the Issue Date except that no Default will be
deemed to have occurred solely by reason of a Restricted Payment made while that section was suspended. Notwithstanding that the suspended sections may be reinstated, no Default will be deemed to have occurred as a result of a failure to comply with
such suspended sections during any period such sections have been suspended.

	 	(5)	default under any Indebtedness for money borrowed by the Company or any of its Significant Subsidiaries, 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 Issue Date, which default 

  

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

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

 If any
Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes and the Trustee may, and the Trustee at the request of such Holders shall, declare all the Notes to be
due and payable immediately. Upon any such declaration, the principal of, premium, if any, and accrued and unpaid interest, if any, and Additional Interest, if any, shall become due and payable immediately. The Trustee has no duty or obligation to
determine whether an Event of Default has occurred as a result of the events described above and shall have notice of such events only in accordance with Section 7.02(i) herein. A Default under clause (4) of Section 6.01 will not

Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, with respect to the Company, all outstanding Notes shall become due and payable without further action or notice. Holders of
the Notes may not enforce this Indenture or the Notes except as provided in this Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust
or power. 
 Any such declaration with respect to the Notes may be rescinded and annulled by the Holders of a majority in aggregate
principal amount of the outstanding Notes by written notice to the Trustee if (i) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction, (ii) all existing Events of Default have been cured or
waived except nonpayment of principal of or interest on the Notes that has become due solely by such declaration of acceleration, (iii) to the extent the payment of such interest is lawful, interest (at the same rate specified in the Notes) on
overdue installments of interest and overdue payments of principal, which has become due otherwise than by such declaration of acceleration, has been paid, (iv) the Company has paid the Trustee its reasonable compensation and reimbursed the
Trustee for its expenses, disbursements and advances and (v) in the event of the cure or waiver of a Default or Event of Default of the type described in clause (7) of Section 6.01 the Trustee has received an Officers’
Certificate and Opinion of Counsel that such Default or Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

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 amount, premium on, Additional Interest, if any, and interest 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. 

Subject to Sections 2.09, 6.07 and 9.02, 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 and
Additional Interest on, if any, or interest on the Notes (including in connection with an offer to purchase); provided, however, that subject to Section 6.02, 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 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: 

 

	 	(1)	the Holder of a Note 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 Notes make a written request to the Trustee to pursue the remedy; 

 

	 	(3)	such Holder or Holders offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; 

 

	 	(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 Notes do not give the Trustee a direction inconsistent with the request. 

A Holder shall not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder.

 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 amount, 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(1) or (2) occurs and is continuing, the Trustee is authorized to recover judgment in

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 the Company (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 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. 
 After an Event of Default, any money or other property distributable in respect of the Company’s obligations
under this Indenture shall be paid in the following order: 
 First: to the Trustee (including any predecessor
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;

Third: to the Company or to such party as a court of competent jurisdiction shall direct in writing. 

  
 -69- 

 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 and expenses, 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 6.11 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 of the then outstanding Notes.

case of a Default in the payment of principal of, interest on, if any, or Additional Interest, if any, with respect to any note, the Trustee may withhold notice if and so long as a committee of

satisfaction of the conditions set forth in Section 8.04 hereof, shall be deemed to have been discharged from all of its 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 Company 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 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 Company, 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 payments in

 Anything in this Article 8 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 (or, if two or more nationally recognized firms of independent public accountants decline to issue such opinion as a matter of policy after the Company has made reasonable efforts
to obtain such an opinion, in the opinion of the Company’s chief financial officer), (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 the 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 or premium,
if any, Additional Interest, if any, or interest on the Notes and remaining unclaimed for two (2) years after such principal, and premium, if any, Additional Interest, 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 Note shall thereafter, as a creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent
with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in 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 shall 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 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 Company has made any payment of principal of, premium, if any, Additional Interest, if any, or interest on any Note following the
reinstatement of its obligations, the Company 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.

SUPPLEMENT AND WAIVER

 (f) conform the text of this Indenture or the

Indenture or the Notes. 
 SECTION 9.02 With Consent of Holders of Notes. 

Except as provided below in this Section 9.02, the Holders of a majority in principal amount of the Notes outstanding can, with respect to
the Notes then outstanding: 
 (a) consent to any amendment or supplement to this Indenture with respect to the Notes; and 

(b) waive any existing default under, or the compliance with any provisions of, this Indenture or the Notes. 

Consents and waivers obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes shall be included for
purposes of the previous paragraph. 
 Subject to Section 9.06, upon the request of the Company accompanied by a resolution of the
Board of Directors of the Company 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. 
 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. 

Without the consent of each Holder of Notes affected, an amendment or waiver under this Section 9.02 with respect to any Notes held by a
non-consenting Holder may not: 
 (a) reduce the principal amount of the Notes;

payment default that resulted from such acceleration; 
 (e) make the Notes 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 the Notes to receive

 (g) waive a
redemption payment, (except a waiver by the Holders of a majority in principal amount of the Notes outstanding of payment upon a required repurchase in connection with an Asset Sale Offer or Change of Control Offer) with respect to the Notes; or

 (h) make any change in this Article 9. 

SECTION 9.03 Compliance with TIA. 

Every amendment or supplement to this Indenture or the Notes shall be set forth in an 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 on receipt by the Trustee of
consents from the Holders of the requisite percentage principal amount of the outstanding Notes, and thereafter shall bind every Holder of Notes; provided, however, if the amendment, supplement or waiver makes a change described in any of the
clauses (a) through (h) of Section 9.02 hereof, the amendment, supplement or waiver shall bind only each Holder of a Note which has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same
indebtedness as the consenting Holder’s Note. 
 SECTION 9.05 Notice of Amendment; Notation on or Exchange of Notes. 

After any amendment under this Article becomes effective, the Company shall mail to Holders of Notes a notice briefly describing such
amendment. The failure to give such notice to all Holders of Notes, or any defect therein, shall not impair or affect the validity of an amendment under this Article. 

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company 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. 

  
 -80- 

 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 9 if the amendment or supplement, in the sole
discretion of the Trustee, does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental indenture until its Board of Directors approves it. In executing any amended or
supplemental indenture, the Trustee shall receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 11.04 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.

recognized firm of independent public accountants (or, if two or more nationally recognized firms of independent public accountants decline to issue such opinion as a matter of policy after the Company has made reasonable efforts to obtain such an
opinion, in the opinion of the Company’s chief financial officer), without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal,
premium and Additional Interest, if any, and accrued interest to the date of maturity or redemption; 
 (b) no Default or
Event of Default has occurred and is continuing on the date of the deposit or shall occur as a result of the deposit and the deposit shall not result in a breach or violation of, or constitute a default under, any other instrument to which the

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 shall thereafter, as an unsecured creditor, look only to the Company for payment thereof, and all liability of
the Trustee or such Paying Agent with respect to such cash and securities, 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 cash and securities remains unclaimed and that, after a date specified therein,

enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Sections 10.01 and 10.02 hereof
until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Sections 10.01 and 10.02 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of,
premium on, if any, or interest or Additional Interest, if any, on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the

 [FORM OF REVERSE OF NOTES] 

4.875% Senior Notes due 2024 

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

1. Interest. SBA Communications Corporation, a Florida corporation (the “Company”), promises to pay interest on the
principal amount of this Note at the rate of 4.875% per annum. The Company will pay interest semi-annually in arrears on March 1 and September 1 of each year, commencing March 1, 2017 or if any such day is not a Business Day, on
the next succeeding Business Day (each an “Interest Payment Date”). Interest on the Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from August 15, 2016. The
Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the rate then in effect; it shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest, if any, (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest
shall be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 2. Method of Payment. The Company shall pay
interest on the Notes (except defaulted interest) and Additional Interest, if any, to the Persons who are registered Holders of Notes at the close of business on the February 15 or August 15 immediately preceding the Interest Payment Date
(each, a “Record Date”), even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture. The Notes shall be payable as to principal or
premium, if any, Additional Interest, if any, or interest at the office or agency of the Company maintained for such purpose within the City and State of New York (which may be an office of the Paying Agent), or, at the option of the Company,
payment of interest and Additional Interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds shall be
required with respect to principal of or premium, if any, Additional Interest, if any, or interest on the Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Company or the Paying Agent prior
to the applicable Record Date. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

3. Paying Agent and Registrar. Initially, U.S. Bank National Association, the Trustee under the Indenture, shall act as Paying Agent
and Registrar. The Company may change any Paying Agent or Registrar without prior notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 

4. Indenture. The Company issued the Notes under an Indenture, dated as of August 15, 2016 (as such may be amended or supplemented
from time to time, the “Indenture”), between the Company and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended
(15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”). The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. To the extent any provision of this Note conflicts
with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are obligations of the Company initially in the aggregate principal amount of $1,100,000,000. Subject to compliance with
Section 2.13 and Section 4.08 of the Indenture, the Company is permitted to issue Additional Notes under the Indenture in an unlimited principal amount. Any such Additional Notes that are actually issued shall be treated as issued and
outstanding Notes of the same class as the Initial Notes of such series for all purposes of the Indenture, unless the context clearly indicates otherwise. 

  
 A-4 

 5. Optional Redemption. 

(a) In addition to the redemption rights set forth in the next paragraph, at any time prior to September 1, 2019, the Company may redeem
all or part of the Notes, upon notice as provided in Section 3.03 of the Indenture, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if
any, and Additional Interest, if any, to, the redemption date. Notice of redemption need not set forth the Applicable Premium but only the manner of calculation of the redemption price. The Indenture provides that, with respect to any such
redemption, the Company will notify the Trustee of the Applicable Premium with respect to the Notes promptly after the calculation and the Trustee will not be responsible for such calculation. 

(b) During the period after the date of original issuance of the Notes until September 1, 2019, upon notice as provided in
Section 3.03 of the Indenture, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes originally issued at a redemption price of 104.875% of the principal amount of the Notes to be redeemed
on the redemption date plus accrued and unpaid interest, if any, and Additional Interest, if any, to the redemption date with the net cash proceeds of one or more Equity Offerings by the Company; provided that

Restricted Subsidiaries to perform any other covenant in the Indenture, other than a covenant specified in clauses (1), (2) or (3) above, that continues for sixty (60) days (or one hundred twenty (120) days in the case of a
failure to comply with the reporting obligations described under Section 4.03 of the Indenture) after notice to comply, (5) default under any Indebtedness for money borrowed by the Company or any of its Significant Subsidiaries, 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 Issue Date, which default (a) is caused by a failure to pay principal of or
premium, if any, interest on, if any, or Additional Interest, if any, with respect to 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 (net of amounts covered by insurance

Restricted Subsidiaries.

bankruptcy or insolvency, with respect to the Company, all outstanding Notes will become due and payable without further action or notice. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate
principal amount of the then outstanding Notes and the Trustee may, and the Trustee at the request of such Holders shall, declare all the Notes to be due and payable immediately. Upon any such declaration, the principal of, premium, if any, and
accrued and unpaid interest, if any, and Additional Interest, if any, shall become due and payable immediately. Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations,
Holders of a majority of the aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. Except in the case of a Default in the payment of principal of, interest on, if any, or Additional
Interest, if any, with respect to any Note, the Trustee may withhold notice if and so long as a committee of its trust officers determines that withholding notice is not opposed to the interest of the Holders of the Notes. 

12. Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

liability for any obligations of the Company under the Notes, the Indenture or the Registration Rights Agreement or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note

FORM OF SUPPLEMENTAL INDENTURE 

SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”) dated as of
                    , 20        , among [GUARANTOR] (the “Guarantor”), SBA
Communications Corporation, a Florida Corporation (together with its successors and assigns, the “Company”), and U.S. Bank National Association, a national banking association, as trustee under the Indenture referred to below (the
“Trustee”). 
 W I T N E S S E T H : 

WHEREAS the Company and the Trustee are parties to that certain Indenture (as such may be amended or supplemented from time to time, the
“Indenture”) dated as of August 15, 2016, providing for the issuance of the Company’s 4.875% Senior Notes due 2024 (the “Notes”); 

WHEREAS pursuant to Section 9.01 of the Indenture, the Trustee, the Company and the Guarantor are authorized to execute and deliver this
Supplemental Indenture; 
 NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of
which is hereby acknowledged, the Guarantor, the Company and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows: 

1. Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture. 

2. Guarantee. The Guarantor hereby unconditionally and irrevocably guarantees, as a primary obligor and not merely as a surety, to each
Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Company hereunder or thereunder,
that: (a) the principal of, premium, if any, interest and Additional Interest, if any, on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of,
premium, and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof;
and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at
stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantor shall be obligated to pay the same immediately. The Guarantor agrees that this
Guarantee is a general unsecured obligation of the Guarantor and it is a guarantee of payment and not a guarantee of collection. 
 The
Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any
Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or
defense of a guarantor. The Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company,
protest, notice and all demands whatsoever and covenants that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and the Indenture. 

  
 E-1 

 The Guarantor also agrees to pay, in addition to the amount stated above, any and all costs and
expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this Section 2. 

If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantor or any custodian, trustee,
liquidator or other similar official acting in relation to either the Company or the Guarantor, any amount paid by the Company or the Guarantor either to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. 
 The Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the
Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. The Guarantor further agrees that, as between the Guarantor, on the one hand, and the Holders and the Trustee, on the other hand,
(x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 of the Indenture for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in
respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 6 of the Indenture, such obligations (whether or not due and payable) shall forthwith become due
and payable by the Guarantor for the purpose of this Guarantee. 
 The Guarantee shall remain in full force and effect and continue to be
effective should any petition be filed by or against the Company or the Guarantor for liquidation or reorganization, should the Company or the Guarantor become insolvent or make an assignment for the benefit of creditors or should a receiver or
trustee be appointed for all or any significant part of the Company’s or the Guarantor’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and
performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or Guarantee, whether as a “voidable preference,” “fraudulent
transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be
reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 
 In case any provision of the
Guarantee shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

The Guarantee issued by the Guarantor shall be a general unsecured senior obligation of the Guarantor and shall (i) rank equally in right
of payment with the Guarantor’s existing and future senior unsecured debt, (ii) rank senior in right of payment to the Guarantor’s future subordinated debt and (iii) be effectively subordinated in right of payment to the
Guarantor’s existing and future secured debt to the extent of the value of the assets securing such debt. 
 Each payment to be made by
the Guarantor in respect of its Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. 
 3.
Limitation on Guarantor Liability. The Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of the Guarantor not

  
 E-2 

 
constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to
the extent applicable to the Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantor hereby irrevocably agree that the obligations of the Guarantor will be limited to such maximum amount as will, after giving
effect to such maximum amount and all other contingent and fixed liabilities of the Guarantor that are relevant under such laws, and result in the obligations of the Guarantor under its Guarantee not constituting a fraudulent transfer or conveyance.

 4. Execution and Delivery. To evidence its Guarantee set forth in Section 2 hereof, the Guarantor hereby agrees that this
Indenture shall be executed on behalf of the Guarantor by an Officer of the Guarantor. 
 The Guarantor hereby agrees that its Guarantee set
forth in Section 2 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes. 

If an Officer whose signature is on this Supplemental Indenture no longer holds that office at the time the Trustee authenticates the Note,
the Guarantee shall be valid nevertheless. 
 The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantor. 
 5. Successors and Assigns. This
Supplemental Indenture shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that
party in this Supplemental Indenture and in the Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture. 

6. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege
under this Supplemental Indenture shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Supplemental Indenture at law, in equity, by statute or otherwise. 

7. No Subrogation. Notwithstanding any payment or payments made by the Guarantor hereunder, the Guarantor shall not be entitled to be
subrogated to any of the rights of the Trustee or any Holder against the Company or any collateral security or Guarantee or right of offset held by the Trustee or any Holder for the payment of the Obligations under the Indenture, nor shall the
Guarantor seek or be entitled to seek any contribution or reimbursement from the Company in respect of payments made by the Guarantor under the Indenture, until all amounts owing to the Trustee and the Holders by the Company on account of the
Obligations under the Indenture are paid in full. If any amount shall be paid to the Guarantor on account of such subrogation rights at any time when all of the Obligations under the Indenture shall not have been paid in full, such amount shall be
held by the Guarantor in trust for the Trustee and the Holders, segregated from other funds of the Guarantor, and shall, forthwith upon receipt by the Guarantor, be turned over to the Trustee in the exact form received by the Guarantor (duly
indorsed by the Guarantor to the Trustee, if required), to be applied against the Obligations under the Indenture. 

  
 E-3 

 8. Guarantor May Consolidate, Etc., on Certain Terms. The Guarantor may not sell or
otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not the Guarantor is the surviving Person) another Person, other than the Company or a future guarantor, unless: 

(1) immediately after giving effect to the transaction, no Default or Event of Default exists; and 

(2) either: 
 (a) the Person
acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger expressly assumes all the obligations of the Guarantor under the Indenture (including its Guarantee) on the terms set forth
herein or therein pursuant to a supplemental indenture in the form hereof; or 
 (b) such sale or other disposition complies with
Section 4.17 of the Indenture, including the application of the Net Proceeds therefrom in accordance with Section 4.17 of the Indenture. 

In case of any such consolidation, merger, sale or other disposition and upon the assumption by the successor Person, by supplemental
indenture in the form hereof, executed and delivered to the Trustee, of the Guarantee and the due and punctual performance of all of the covenants and conditions of the Indenture to be performed by the Guarantor, such successor Person shall succeed
to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. The Guarantee shall in all respects have the same legal rank and benefit under the Indenture as the Guarantee theretofore and thereafter
issued in accordance with the terms of the Indenture as though such Guarantee had been issued at the date of the execution of the Indenture. 

Except as set forth in Articles 4 and 5 of the Indenture, and notwithstanding clauses (a) and (b) above, nothing contained in the
Indenture or in any of the Notes shall prevent any consolidation or merger of the Guarantor with or into the Company, or shall prevent any sale or conveyance of the property of the Guarantor as an entirety or substantially as an entirety to the
Company. 
 9. Releases of Guarantee. The Guarantor shall be deemed released from all its obligations under the Indenture, this
Supplemental Indenture and its Guarantee with respect to the Notes and such Guarantee shall terminate (i) upon the satisfaction and discharge of this Indenture with respect to the Notes, (ii) upon the legal defeasance of the Notes, in each
case, pursuant to the provisions of Article 8 of the Indenture, or (iii) upon any sale, exchange or transfer, (a) of the Guarantor to any Person other than a Subsidiary of the Company, (b) of all of the Company’s stock in such
Guarantor, or (c) of all or substantially all the assets of, such Guarantor, which sale, exchange or transfer is made in compliance with the applicable provisions of the Indenture. 

10. Ratification of Indenture; Supplemental Indentures Part of Indenture. Except as expressly supplemented hereby, the Indenture is in
all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect. This Supplemental Indenture shall form a part of the Indenture for all purposes, and every Holder of Notes heretofore or
hereafter authenticated and delivered shall be bound hereby. 
 11. Governing Law; Waiver of Jury Trial. THIS SUPPLEMENTAL
INDENTURE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. EACH OF THE COMPANY, THE HOLDERS AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO
TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS SUPPLEMENTAL INDENTURE. 

  
 E-4 

 12. Trustee Makes No Representation. The Trustee makes no representation as to the
validity or sufficiency of this Supplemental Indenture. 
 13. Counterparts. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. The exchange of copies of this Supplemental Indenture and of signature pages by facsimile or PDF transmission shall constitute
effective execution and delivery of this Supplemental Indenture as to the parties hereto and may be used in lieu of the original Indenture and signature pages for all purposes.
