 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, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the
Trustee or the Company, 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 may charge for its expenses in replacing a Note.

accrue. 
  
 If the Paying Agent (other than the
Company, a Subsidiary of the Company or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay

though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned shall be so disregarded.

Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or in accordance with any other method the Trustee shall deem fair and appropriate; provided that no Notes of $1,000 in aggregate principal amount or less shall
be redeemed in part. In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, 

  

 - 42 - 

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

no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. 
  
 At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided,
however, that the Company shall have delivered to the Trustee, at least 45 days prior to the redemption date, an Officers’ Certificate requesting 

  

 - 43 - 

 
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.

Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional. 
  
 SECTION 3.05. Deposit of Redemption Price. 
  
 One Business Day prior to the redemption date, the Company shall deposit with the Trustee or with the Paying

Company in excess of the amounts necessary to pay the redemption price of, and accrued 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 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.

Holder is withdrawing his election to have such Note purchased;

purchased on a pro rata basis

thereof, shall be purchased); and 
  
 (i) that
Holders whose Notes were purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). 
  
 On or before the Purchase Date, the Company shall, to the
extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes and Pari Passu Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all

Subsidiary of the Company held by any member of the Company’s (or any of its Restricted Subsidiaries’) management; provided that the aggregate amount expended pursuant to this clause (iv) shall not exceed $500,000 in any
twelve-month period; 
  
 (v) the repurchase of
Equity Interests of the Company that may be deemed to occur upon the exercise of options to acquire capital stock of the Company if such Equity Interests represent a portion of the exercise price of such options; or 
  
 (vi) cash payments, in lieu of fractional shares issuable as
dividends on Equity Interests of the Company, in an amount, when taken together with all other cash payments made pursuant to this clause (vi) since the Issue Date, not to exceed $500,000. 
  

 - 52 - 

 The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted
Subsidiary if such Subsidiary, after giving effect to such designation, would meet the requirements of the definition of “Unrestricted Subsidiary.” The Company shall not, and shall not permit any of its Subsidiaries to, enter into, or
suffer to exist, any transaction or arrangement, with a Subsidiary that is an Unrestricted Subsidiary that would be inconsistent with or violate the terms set forth in the definition of “Unrestricted Subsidiary.” 
  
 The amount of all Restricted Payments (other than cash),
including the amount of the Restricted Payment that will be deemed to occur upon the designation of a Subsidiary as an Unrestricted Subsidiary, shall be the fair market value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Company or the applicable Restricted Subsidiary, or of the Company’s proportionate interest in the Subsidiary so to be designated as the case may be, pursuant to the Restricted Payment. 
  
 SECTION 4.08. Limitation on Dividends and Other Distributions from
Restricted Subsidiaries. 
  
 The 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
(i) (a) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries (x) on its Capital Stock or (y) with respect to any other interest or participation in, or measured by, its profits, or (b) pay any
indebtedness owed to the Company or any of its Restricted Subsidiaries; (ii) make loans or advances to the Company or any of its Restricted Subsidiaries; or (iii) transfer any of its properties or assets to the Company or any of its Restricted
Subsidiaries. 
  
 However, the foregoing
restrictions will not apply to encumbrances or restrictions existing under or by reason of (a) any agreement or instrument governing Existing Indebtedness as in effect on the Issue Date or as amended, modified, restated or renewed in any manner not
materially more restrictive, taken as a whole, (b) the Indenture or the Notes, (c) applicable law, (d) 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 of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any
Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the Indenture to be incurred, (e) by reason of customary non-assignment
provisions in leases or licenses or other contracts entered into in the ordinary course of business, (f) purchase money obligations for property acquired in the ordinary course of business that impose restrictions of the nature described in clause
(iii) above on the property so acquired, (g) the provisions of agreements governing Indebtedness incurred pursuant to clause (iv) of the second paragraph of Section 4.09, (h) any agreement for the sale of a Restricted Subsidiary that restricts that
Restricted Subsidiary pending its sale, (i) any Credit Facility or Permitted Refinancing Indebtedness, provided that the restrictions contained such Credit Facility or in the agreements governing such Permitted Refinancing Indebtedness are
not materially more restrictive, taken as a whole, than those contained in the Senior Credit Facility as of the Issue Date with respect to a Credit Facility, or the agreements governing the Indebtedness being refinanced with respect to 

  

 - 53 - 

 
Permitted Refinancing Indebtedness, as applicable, (j) Liens permitted to be incurred pursuant to the provisions of Section 4.12 that limit the right of the
debtor to transfer the assets subject to such Liens, (k) any Indebtedness incurred in compliance with Section 4.09 or any agreement pursuant to which such Indebtedness is issued if the encumbrance or restriction applies only in the event of a
payment default or default with respect to a financial covenant contained in the Indebtedness or agreement and the encumbrance or restriction is not materially more disadvantageous to the Holders of the Notes than is customary in comparable
financings (as determined by the 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, (l) provisions with respect to the
disposition or distribution of assets or property in joint venture agreements and other similar agreements and (m) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of
business. 
  
 SECTION 4.09. Limitation on Incurrence of
Indebtedness and Issuance of Preferred Stock. 
  
 The 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 will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided,
however, that (x) the Company may incur Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock if (1) no Default shall have occurred and be continuing or would occur as a consequence thereof and (2) the Company’s Debt
to Adjusted Consolidated Cash Flow Ratio at the time of incurrence of such Indebtedness or the issuance of such Disqualified Stock, after giving pro forma effect to such incurrence or issuance as of such date and to the use of proceeds therefrom
would have been no greater than 8.5 to 1.0 and (y) SBA Senior Finance may incur Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock and the other Restricted Subsidiaries of the Company may incur Indebtedness or issue
preferred stock if, in each case, (1) no Default shall have occurred and be continuing or would occur as a consequence thereof and (2) SBA Senior Finance’s Debt to Adjusted Consolidated Cash Flow Ratio at the time of incurrence of such
Indebtedness or the issuance of such Disqualified Stock or preferred stock, after giving pro forma effect to such incurrence or issuance as of such date and to the use of proceeds therefrom, would have been no greater than 5.5 to 1.0. 
  
 The first paragraph of this covenant shall not apply to the
incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”) if no Default shall have occurred and be continuing or would occur as a consequence thereof: 
  
 (i) the incurrence by the Company or any of its Restricted
Subsidiaries of Indebtedness under one or more Credit Facilities or through the issuance of Seller Paper in an aggregate principal amount (with letters of credit being deemed to have an aggregate principal amount equal to the maximum potential
liability of the Company and its Restricted Subsidiaries thereunder) at any one time outstanding not to exceed $300.0 million less (i) the aggregate amount of commitment reductions under Credit Facilities resulting from the application of
proceeds of Asset Sales since the Issue 

  

 - 54 - 

 
Date and (ii) the aggregate amount of outstanding Consolidated Indebtedness of SBA Senior Finance incurred pursuant to the first paragraph of this covenant;
provided, however, that the aggregate principal amount of Seller Paper at any one time outstanding under this clause (i) shall not exceed $50.0 million; 
  

(ii) the incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness; 
  
 (iii) the incurrence by the Company of Indebtedness
represented by the Notes (other than Additional Notes), and the Exchange Notes issued in exchange therefore; 
  
 (iv) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations,
mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the 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 pursuant to this clause (iv), not to exceed $20.0 million at
any one time outstanding; 
  
 (v) 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 (other than intercompany
Indebtedness) that was permitted by the Indenture to be incurred under the first paragraph hereof or clause (ii) or (iii) or this clause (v) of this paragraph; 
  

(vi) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness or intercompany preferred stock
between or among the Company and any of its Restricted Subsidiaries; provided, however, that (1) 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 (2)(A) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness or preferred stock being held by a Person other than the Company or a Restricted Subsidiary and (B) any
sale or other transfer of any such Indebtedness or preferred stock to a Person that is not either the Company or a Restricted Subsidiary shall be deemed, in each case, to constitute an incurrence of such Indebtedness or issuance of such preferred
stock by the Company or such Restricted Subsidiary, as the case may be; 
  
 (vii) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations that are incurred for the purpose of fixing or hedging interest rate risk with respect to any floating rate Indebtedness
that is permitted by the terms of the Indenture to be outstanding or currency exchange risk or otherwise entered into for bona fide purposes designed to protect against interest rate or currency exchange risk and not for speculative purposes;

  

 - 55 - 

 (viii) 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 the Indenture; 
  
 (ix) the incurrence by the Company or any of its Restricted Subsidiaries of Acquired Debt in connection with the acquisition of assets or
a new Subsidiary and the incurrence by the Company’s Restricted Subsidiaries of Indebtedness as a result of the designation of an Unrestricted Subsidiary as a Restricted Subsidiary; provided that, in the case of any such incurrence of
Acquired Debt, such Acquired Debt was incurred by the prior owner of such assets or such Restricted Subsidiary prior to such acquisition by the Company or one of its Restricted Subsidiaries and was not incurred in connection with, or in
contemplation of, such acquisition by the Company or one of its Restricted Subsidiaries; and provided further that, as a result of such incurrence, in the case of Acquired Debt incurred directly by the Company, the Company’s Debt to
Adjusted Consolidated Cash Flow Ratio and, in the case of Acquired Debt incurred by SBA Senior Finance or any other Restricted Subsidiary of the Company, the Company’s Debt to Adjusted Consolidated Cash Flow Ratio and SBA Senior Finance’s
Debt to Adjusted Consolidated Cash Flow Ratio, in each case, at the time of incurrence of such Acquired Debt, after giving pro forma effect to such incurrence as if the same had occurred at the beginning of the most recently ended four full fiscal
quarter period for the Company for which internal financial statements are available, would have been less than or equal to, in the case of Acquired Debt incurred directly by the Company, the Company’s Debt to Adjusted Consolidated Cash Flow
Ratio and, in the case of Acquired Debt incurred by SBA Senior Finance or any other Restricted Subsidiary of the Company, the Company’s Debt to Adjusted Consolidated Cash Flow Ratio and SBA Senior Finance’s Debt to Adjusted Consolidated
Cash Flow Ratio, respectively, for the same period without giving pro forma effect to such incurrence; and 
  
 (x) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or
accreted value, as applicable) at any time outstanding not to exceed $25.0 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. The Company shall not permit any of its Unrestricted Subsidiaries to incur any Indebtedness other than Non-Recourse Debt. Restricted Subsidiaries of the
Company may not issue or sell, and the Company may not permit any Restricted Subsidiary of the Company to have outstanding, any Equity Interests (other than (x) Equity Interests held by the Company or its Restricted Subsidiaries or (y) Permitted
Subsidiary Equity Interests). 
  
 For purposes of
determining compliance with this Section 4.09, in the event that an item of Indebtedness or preferred stock meets the criteria of more than one of the categories of Permitted Debt described in clauses (i) through (x) in the second paragraph of this
Section 4.09 or is entitled to be incurred pursuant to the first paragraph of this Section 4.09, the Company 

  

 - 56 - 

 
shall, in its sole discretion, classify or reclassify such item of Indebtedness in any manner that complies with this Section 4.09. Accrual of interest,
accretion or amortization of original issue discount and the payment of interest in the form of additional Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes of this covenant. 
  
 SECTION 4.10. Limitation on Asset Sales. 
  
 The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, consummate an Asset Sale unless (i) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value (evidenced by a resolution
of the Board of Directors set forth in an Officers’ Certificate delivered to the Trustee) of the assets or Equity Interests issued or sold or otherwise disposed of and (ii) at least 75% of the consideration therefor received by the Company or
such Restricted Subsidiary is in the form of (a) cash or Cash Equivalents, (b) Tower Assets or (c) any combination of the foregoing; provided that the amount of (x) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s
most recent balance sheet) of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any guarantee thereof) that are assumed by the transferee of any such
assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability and (y) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such
transferee that are converted by the Company or such Restricted Subsidiary into cash within 20 days of the applicable Asset Sale (to the extent of the cash received), shall be deemed to be cash for purposes of this provision. 
  
 Within 360 days after the receipt of any Net Proceeds from
an Asset Sale, the Company or the applicable Restricted Subsidiary may apply such Net Proceeds to: (a) reduce (which reduction may be temporary) Indebtedness under a Credit Facility; (b) reduce or repurchase any other Indebtedness of any of the
Company’s Restricted Subsidiaries, including the 2011 Notes; (c) reduce or repurchase any Indebtedness represented by the Notes; (d) reduce or repurchase any Senior Indebtedness of the Company, excluding the 2011 Notes; provided that the
Notes are reduced or repurchased on a pro rata basis with the Net Proceeds from such Asset Sale; (e) acquire all or substantially all the assets of a Permitted Business; provided, that after giving effect thereto, the Company and/or a
Restricted Subsidiary own such assets; (f) acquire Voting Stock of a Permitted Business from a Person that is not a Subsidiary of the Company; provided, that, after giving effect thereto, the Company and/or a Restricted Subsidiary own a
majority of such Voting Stock; or (g) make a capital expenditure or acquire other long-term assets that are used or useful in a Permitted Business; provided, that after giving effect thereto, the Company or a Restricted Subsidiary of the
Company is the owner of such assets. Pending the final application of any such Net Proceeds, the Company or the applicable Restricted Subsidiary may invest such Net Proceeds in any manner that is not prohibited by the Indenture. Any Net Proceeds
from Asset Sales that are not applied or invested as provided in preceding sentence of this paragraph will be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company or
the applicable Restricted Subsidiary will be required to make an offer (an “Asset Sale Offer”) to all Holders of Notes and all holders of other Senior Indebtedness of the Company, excluding the 2011 Notes, containing provisions
similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (such other Senior Indebtedness, “Pari Passu Notes”) to purchase, on 

  

 - 57 - 

 
a pro rata basis, the maximum principal amount (or accreted value, as applicable) of Notes and such Pari Passu Notes that may be purchased out of the Excess
Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount (or accreted value, as applicable) thereof plus accrued and unpaid interest and Additional Interest thereon, if any, to the date of purchase (subject to the right
of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), in accordance with the procedures set forth in the Indenture and the instruments governing such Pari Passu Notes. To the extent that any
Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount (or accreted value, as applicable) of Notes and
Pari Passu Notes tendered into such Asset Sale Offer surrendered by Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such Pari Passu Notes to be purchased on a pro rata basis based on the aggregate
principal amount (or accreted value, as applicable) of Notes or Pari Passu Notes tendered. Upon completion of such offer to purchase, the amount of Excess Proceeds shall be reset at zero. 
  
 The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations applicable to any Asset Sale Offer. To the extent that the provisions of any such securities laws or securities regulations conflict with the provisions
of the covenant described above, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the covenant described above by virtue thereof. 
  
 SECTION 4.11. Limitation on Transactions with Affiliates. 

 
 The 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 (each of the foregoing, an “Affiliate Transaction”), unless (i) 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 and (ii) the Company delivers to the Trustee (a) with respect to any
Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $2.5 million, a resolution of the Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate
Transaction complies with clause (i) above and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors and (b) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $10.0 million, an opinion as to the fairness to the Holders of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of
national standing. Notwithstanding the foregoing, the following items shall not be deemed to be Affiliate Transactions: (i) any employment arrangements with any executive officer of the Company or a Restricted Subsidiary that is entered into by the
Company or any of its Restricted Subsidiaries in the ordinary course of business and consistent with compensation arrangements of similarly situated executive officers at comparable companies engaged in Permitted Businesses, (ii) transactions
between or among the Company and/or its Restricted Subsidiaries, (iii) payment of outside directors’ fees in an aggregate annual amount not to exceed 

  

 - 58 - 

 
$50,000 per Person, (iv) Restricted Payments and Permitted Investments that are permitted by Section 4.07 and (v) the issuance or sale of Equity Interests
(other than Disqualified Stock) of the Company. 
  
 SECTION 4.12.
Limitation on Liens. 
  
 The Company shall
not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien securing Indebtedness or trade payables on any asset now owned or hereafter acquired, or any income or profits
therefrom or assign or convey any right to receive income therefrom, except Permitted Liens, unless (A) in the case of the Liens securing Indebtedness that is expressly subordinate or junior in right of payment to the Notes, the Notes are secured by
a Lien on those assets or income or profits that is senior in priority to those Liens, with the same relative priority as that subordinate or junior Indebtedness will have with respect to the Notes and (B) in all other cases, the Notes are secured
on an equal and ratable basis, in each case, until such time as such Indebtedness is no longer secured by a Lien. 
  
 SECTION 4.13. Limitation on Business Activities. 
  
 The Company shall not, and shall not permit any Restricted Subsidiary to, engage in any business other than Permitted Businesses, except
to such extent as would not be material to the Company and its Restricted Subsidiaries taken as a whole. 
  
 SECTION 4.14. Corporate Existence. 
  
 Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect
(i) its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any
such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the
corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted
Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes. 
  
 SECTION 4.15. Offer to Repurchase upon Change of Control. 
  

(a) Upon the occurrence of a Change of Control, each Holder of Notes shall have the right to require the Company to purchase all or any
part (equal to $1,000 or an integral multiple thereof) of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”) at an offer price in cash equal to 101% of the aggregate principal amount
thereof plus accrued and unpaid interest and Additional Interest thereon, if any (subject to the right of Holders of record on the relevant record date to receive interest and Additional Interest due on the relevant interest payment date), to the
date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company shall mail a notice to each Holder stating: (i) that the Change of Control Offer is being made pursuant to this Section
4.15 

  

 - 59 - 

 
and that all Notes tendered will be accepted for payment; (ii) the purchase price and the purchase date, which shall be no earlier than 30 days and no later
than 60 days from the date such notice is mailed (the “Change of Control Payment Date”); (iii) that any Note not tendered will continue to accrue interest; (iv) that, unless the Company defaults in the payment of the Change of
Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Change of Control Payment Date; (v) that Holders electing to have any Notes purchased pursuant to a Change of Control
Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes completed, to the Paying Agent at the address specified in the notice prior to the close of business on
the third Business Day preceding the Change of Control Payment Date; (vi) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of
Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes
purchased; and (vii) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in principal
amount or an integral multiple thereof. 
  
 (b)
On the Change of Control Payment Date, the Company shall, to the extent lawful, (i) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an amount equal to the
Change of Control Payment in respect of all Notes or portions thereof so tendered and (iii) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of
Notes or portions thereof being purchased by the Company. The Paying Agent shall promptly mail to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be
transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note shall be in a principal amount of $1,000 or an integral multiple thereof.

  
 (c) The Company shall not be required to make
a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer
made by the Company and purchases all Notes validly tendered and not withdrawn under such 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 may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes then outstanding. 
  
 (d) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other
securities laws or regulations applicable to any Change of Control Offer. To the extent that the provisions of any such securities laws or securities regulations conflict with the provisions of the covenant described above, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the covenant described above by virtue thereof.

 SECTION 4.16. Limitation on Sale and Leaseback Transactions. 
  
 The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, enter into any sale and leaseback transaction (as seller); provided that the Company or any of its Restricted Subsidiaries may enter into a sale and leaseback transaction if (i) the Company or such Restricted Subsidiary,
as applicable, could have (a) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction (x), in the case of the Company, pursuant to the Company’s Debt to Adjusted Consolidated Cash Flow
Ratio test set forth in the first paragraph of Section 4.09, and (y) in the case of SBA Senior Finance and any other Restricted Subsidiary of the Company pursuant to SBA Senior Finance’s Debt to Adjusted Consolidated Cash Flow Ratio test set
forth in the first paragraph of Section 4.09 and (b) incurred a Lien to secure such Indebtedness pursuant to Section 4.12, (ii) the gross cash proceeds of such sale and leaseback transaction are at least equal to the fair market value (as determined
in good faith by the Board of Directors) of the property that is the subject of such sale and leaseback transaction and (iii) the transfer of assets in such sale and leaseback transaction is permitted by, and the Company applies the proceeds of such
transaction in compliance with, Section 4.10. 
  
 SECTION 4.17.
Limitation on Issuances of Guarantees of Indebtedness. 
  
 The Company will not permit any Restricted Subsidiary, directly or indirectly, to Guarantee or pledge any assets to secure the payment of any Indebtedness of the Company (except Indebtedness of the Company under a
guarantee of Indebtedness of one or more of its Restricted Subsidiaries) unless such Restricted Subsidiary simultaneously executes and delivers a supplemental indenture to this Indenture providing for the Guarantee of the payment of the premium, if
any, principal, interest and Additional Interest, if any, on the Notes by such Restricted Subsidiary, which Guarantee shall be senior to or pari passu with such Restricted Subsidiary’s Guarantee of or pledge to secure such other
Indebtedness. Notwithstanding the foregoing, any such Guarantee by a Restricted Subsidiary of the Notes shall provide by its terms that it shall be automatically and unconditionally released and discharged upon any sale, exchange or transfer, to any
Person other than a Restricted Subsidiary, of all of the Company’s stock in, or all or substantially all the assets of, such Restricted Subsidiary, which sale, exchange or transfer is made in compliance with the applicable provisions of the
Indenture. The form of such supplemental indenture providing for the Guarantee is attached as Exhibit E hereto.

 SUCCESSORS 
  
 SECTION 5.01. Merger, Consolidation or Sale of Assets. 
  
 The Company may not consolidate or merge with or into (whether or not the Company is the surviving
corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions to another corporation, Person or entity unless (i) the Company is the surviving
corporation or the entity or the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition 

  

 - 61 - 

 
shall have been made is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia; (ii) the
entity or Person formed by or surviving any such consolidation or merger (if other than the Company) or the entity or Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the
obligations of the Company under the Notes and this Indenture and the Registration Rights Agreement pursuant to agreements reasonably satisfactory to the Trustee; (iii) immediately after such transaction no Default or Event of Default exists; and
(iv) immediately after the transaction and after giving pro forma effect thereto as if the transaction had occurred at the beginning of the applicable four-quarter period, (A) the Company or the entity or Person formed by or surviving any such
consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made will be permitted to incur at least $1.00 of additional Indebtedness pursuant to the
Company’s Debt to Adjusted Consolidated Cash Flow Ratio test set forth in the first paragraph of Section 4.09, or (B) the Company’s Debt to Adjusted Consolidated Cash Flow Ratio shall be less than or equal to, the Company’s Debt to
Adjusted Consolidated Cash Flow Ratio and for the same period without giving pro forma effect to such transaction. 
  
 SECTION 5.02. Successor Corporation Substituted. 
  
 Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of
the assets of the Company in accordance with Section 5.01 hereof, the successor corporation formed by such consolidation or into or with which the Company is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition
is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to “the Company” shall refer instead
to the successor corporation and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein, provided, however, that the
predecessor company shall not be relieved from the obligation to pay the principal of and interest on the Notes except in the case of a sale of all of the Company’s assets that meets the requirements of Section 5.01 hereof.

 (b) the Company defaults in the payment when due of principal of or premium, if any, on the Notes when the
same becomes due and payable at maturity, upon redemption (including in connection with an offer to purchase) or otherwise;

 (e) a default occurs under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced 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, or interest on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”) or (b) results in the acceleration of
any such Indebtedness prior to its Stated Maturity and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which
has been so accelerated, aggregates $10.0 million or more; 
  
 (f) a final judgment or final judgments for the payment of money are entered by a court or courts of competent jurisdiction against the Company or any of its Significant Subsidiaries or any group of Subsidiaries that,

judgments exceeds $10.0 million; 
  
 (g) the
Company or any of its Restricted Subsidiaries that is a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law:

unstayed and in effect for 60 consecutive days. 
  
 SECTION 6.02.
Acceleration. 
  
 If any Event of Default
(other than an Event of Default specified in clause (g) or (h) of Section 6.01 hereof with respect to the Company, any Significant Subsidiary or any group of Significant Subsidiaries that, taken as a whole, would constitute a Significant
Subsidiary), occurs and is continuing, the Trustee, by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Notes, by notice to the Company and the Trustee, may 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. Notwithstanding the foregoing, if an Event of Default
specified in clause (g) or (h) of Section 6.01 hereof occurs with respect to the Company, any of its Significant Subsidiaries or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, the principal of, premium,
if any, and accrued and unpaid interest, if any, and Additional Interest, if any, shall be due and payable immediately without further action or notice. The Holders of a majority in aggregate principal amount of the Notes then outstanding by written
notice to the Trustee may on behalf of all of the Holders of all the Notes waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in payment of interest or premium or
Additional Interest on, or the principal of, the Notes. 
  
 SECTION 6.03. Other Remedies. 
  
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, interest and Additional Interest, if any, on the Notes or to enforce the performance of any
provision of the Notes or this Indenture. 
  
 The
Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of
Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
  
 SECTION 6.04. Waiver of Past Defaults. 
  
 Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to
the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or
interest or Additional Interest on, the Notes (including in connection with an offer to purchase) (provided, 

  

 - 64 - 

 
however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration). Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture;
but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 
  
 SECTION 6.05. Control by Majority. 
  
 Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. 
  
 SECTION 6.06. Limitation on Suits. 
  
 A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if: 
  
 (a) the Holder of a Note gives to the Trustee written notice
of a continuing Event of Default; 
  
 (b) 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; 
  
 (c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee
against any loss, liability or expense; 
  
 (d)
the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and 
  
 (e) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a
direction inconsistent with the request. 
  
 A
Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. 
  
 SECTION 6.07. Rights of Holders of Notes to Receive Payment. 
  
 Notwithstanding any other provision of this Indenture, the
right of any Holder of a Note to receive payment of principal, premium and Additional Interest, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to
bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 
  

 - 65 - 

 SECTION 6.08. Collection Suit by Trustee. 
  
 If an Event of Default specified in Section 6.01(a) or (b)
occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium and Additional Interest, if any, and interest remaining
unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel. 
  
 SECTION
6.09. Trustee May File Proofs of Claim. 
  
 The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to 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. 
  
 If the Trustee collects any money pursuant to this Article,
it shall pay out the money in the following order: 
  
 First: to
the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
  
 Second: to Holders of Notes for amounts due and unpaid on the Notes for
principal, premium and Additional Interest, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on 

  

 - 66 - 

 
the Notes for principal, premium and Additional Interest, if any and interest, respectively; and 
  
 Third: to the Company or to such party as a court of competent jurisdiction
shall direct. 
  
 The Trustee may fix a record date and payment
date for any payment to Holders of Notes pursuant to this Section 6.10. 
  
 SECTION 6.11. Undertaking for Costs. 
  
 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the
suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of
the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding
Notes. 
  
 ARTICLE 7. 
 TRUSTEE 
  
 SECTION 7.01. Duties of Trustee. 
  
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 
  
 (b) Except during the continuance of an Event of Default: 
  
 (i) the duties of the Trustee shall be determined solely by
the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee;
and 
  
 (ii) in the absence of bad faith on its
part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However,
the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

 (e) No provision of this Indenture shall require the Trustee
to expend or risk its own funds or incur any liability. The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder shall have offered to the Trustee
security and indemnity satisfactory to it against any loss, liability or expense. 
  
 (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company.
Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 
  
 SECTION 7.02. Rights of Trustee. 
  
 (a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper
Person. The Trustee need not investigate any fact or matter stated in the document.

 SECTION 7.03. Individual Rights of Trustee. 
  
 The Trustee in its individual or any other capacity may
become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. 
  
 SECTION 7.04. Trustee’s Disclaimer. 
  
 The Trustee shall not be responsible for and makes no

or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. 
  
 SECTION 7.05. Notice of Defaults. 
  
 If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a
notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest or Additional Interest on any Note, the Trustee may withhold the
notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is not opposed to the interests of the Holders of the Notes. 
  
 SECTION 7.06. Reports by Trustee to Holders of the Notes. 
  
 Within 60 days after each May 15 beginning with the May 15
following the Issue Date, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA §
313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA § 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA § 313(c).

 A copy of each report at the time of its mailing to the Holders of Notes shall be mailed
to the Company and filed with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange. 
  
 SECTION 7.07. Compensation and Indemnity.

Indenture against the Company (including this Section 7.07) and defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers
or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to
so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees
and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. 
  
 The obligations of the Company under this Section 7.07 shall survive the satisfaction and discharge of this Indenture. 
  
 To secure the Company’s payment obligations in this
Section, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge
of this Indenture. 
  
 When the Trustee incurs
expenses or renders services after an Event of Default specified in Section 6.01(g) or (h) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute
expenses of administration under any Bankruptcy Law.

successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section. 
  
 The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of
Notes of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if:

insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

 If the Trustee resigns or is removed or if a vacancy exists
in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company. 
  
 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of Notes of at least 10% in principal amount of the then
outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
  
 If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply
with Section 7.10, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
  
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the
Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of
its succession to Holders of the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in
Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. 
  

 - 71 - 

 SECTION 7.09. Successor Trustee by Merger, etc.

 SECTION 8.01. Option to Effect Legal Defeasance or Covenant
Defeasance.

to the Trustee all outstanding Notes (other than Notes replaced pursuant to Section 2.07) for cancellation or (ii) all outstanding Notes have become due and payable, whether at maturity or as a result of the mailing of a notice of redemption
pursuant to Article 3 hereof and the Company irrevocably deposits with the Trustee funds sufficient to pay at maturity or upon redemption all outstanding Notes, including interest thereon to maturity or such redemption date (other than Notes
replaced pursuant to Section 2.07), and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to the proviso set forth in Section 8.02, cease to be of further effect. The Company may,
at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof applied to all outstanding Notes upon compliance with the conditions set
forth below in this Article Eight. 
  
 SECTION 8.02. Legal
Defeasance and Discharge. 
  
 Upon the
Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its
obligations with respect to all outstanding Notes and this Indenture on the date the conditions set forth below are satisfied 

  

 - 72 - 

 
(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 the other Sections of this Indenture referred to in (a) and (b) below, and to
have satisfied all its other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the 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 solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in
respect of the principal of, premium, if any, and interest and Additional Interest on such Notes when such payments are due, (b) the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof, (c) the rights,
powers, trusts, duties and immunities of the Trustee hereunder and the Company’s obligations in connection therewith and (d) this Article Eight. Subject to compliance with this Article Eight, the Company may exercise its option under this
Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. 
  
 SECTION 8.03. Covenant Defeasance. 
  
 Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released
from its obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16 and 4.17 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied
(hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason
of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under
Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03
hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(d) through 6.01(f) hereof shall not constitute Events of Default. 
  

 - 73 -

 The following shall be the conditions to the application of
either Section 8.02 or 8.03 hereof to the outstanding Notes: 
  
 In order to
exercise either Legal Defeasance or Covenant Defeasance: 
  
 (a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in United States dollars, non-callable Government Securities, or a combination thereof, in such amounts as will
be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest and Additional Interest on the outstanding Notes on their Stated Maturity or on the applicable
redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to maturity or to a particular redemption date;

 SECTION 8.05. Satisfaction and Discharge 
  
 This Indenture will be discharged and will cease to be of
further effect as to all Notes issued hereunder, when:

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 (other than a Default or Event of Default

counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 
  
 SECTION 8.06. Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions. 
  
 Subject to Section 8.06 hereof, all money and non-callable
Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding
Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee
may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, interest and Additional Interest, if any, but such money need not be segregated from other funds except to the extent
required by law. 
  
 The Company shall pay and
indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than
any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 
  
 Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the
request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 

 
 SECTION 8.07. Repayment to Company. 
  
 Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and payable shall be paid to
the 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 secured 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. 
  
 SECTION 8.08. 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 

  

 - 76 - 

 
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 makes any payment of principal of, premium, 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. 
  
 ARTICLE 9. 
 AMENDMENT, SUPPLEMENT AND WAIVER 
  
 SECTION 9.01. Without Consent of Holders of Notes. 
  
 Notwithstanding Section 9.02 of this Indenture, the Company and the Trustee may amend or supplement this Indenture or the Notes without
the consent of any Holder of a Note: 
  
 (a) to
cure any ambiguity, defect or inconsistency; 
  
 (b) to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions of Article 2 hereof (including the related definitions) in a manner that does not materially adversely affect any Holder;

  
 (c) to provide for the assumption of the
Company’s obligations to the Holders of the Notes by a successor to the Company in accordance with the provisions of this Indenture or pursuant to Article 5 hereof; 
  
 (d) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this
Indenture; 
  
 (e) to make any change that would
provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder of the Note; 
  

(f) to provide for the guarantee of the Notes by a Restricted Subsidiary in accordance with Section 4.17; 
  
 (g) to comply with requirements of the SEC in order to
effect or maintain the qualification of this Indenture under the TIA. 
  
 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the Trustee of the documents described
in Section 7.02 hereof, the Trustee shall join with the Company in the execution of any amended or supplemental Indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may
be therein contained, but the Trustee shall not be obligated to enter into 

  

 - 77 - 

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

 - 78 - 

 (b) reduce the principal of or change the fixed maturity of any Note or alter or waive
any of the provisions with respect to the redemption of the Notes except as provided above with respect to Sections 3.09, 4.10 and 4.15 hereof; 
  
 (c) reduce the rate of or change the time for payment of interest or Additional Interest, including default interest, on any Note;

  
 (d) waive a Default or Event of Default in
the payment of principal of or premium, if any, or interest or Additional Interest on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a
waiver of the payment default that resulted from such acceleration); 
  
 (e) make any Note payable in money other than that stated in the Notes; 
  
 (f) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive
payments of principal of, premium, if any, or interest or Additional Interest, if any, on the Notes; 
  
 (g) change the ranking of the Notes, or 
  
 (h) make any change in Section 6.04 or 6.07 hereof or in the foregoing amendment and waiver provisions. 
  
 SECTION 9.03. Compliance with Trust Indenture Act. 
  
 Every amendment or supplement to this Indenture or the Notes
shall be set forth in 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 in accordance with its
terms and thereafter binds every Holder. 
  
 SECTION 9.05.
Notation on or Exchange of Notes. 
  
 The
Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The 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. 
  

 - 79 - 

 Failure to make the appropriate notation or issue a new Note shall not affect the
validity and effect of such amendment, supplement or waiver. 
  
 SECTION 9.06. Trustee to Sign Amendments, etc. 
  
 The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article Nine if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the
Trustee. The Company may not sign an amendment or supplemental Indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof)
shall be fully protected in relying upon, in addition to the documents required by Section 10.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or
permitted by this Indenture.

Default”) or (b) results in the acceleration of such Indebtedness prior to its Stated Maturity and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness under which there has
been a Payment Default or the maturity of which has been so accelerated, aggregates to $10.0 million or more; (vi) certain final judgments for the payment of money that remain undischarged for a period of 60 days provided that the aggregate of all

the Notes then outstanding by written notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in
the payment of interest or premium or Additional Interest on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming

 FORM OF SUPPLEMENTAL INDENTURE 
 TO BE DELIVERED BY SUBSEQUENT GUARANTORS 
  
 Supplemental Indenture (this “Supplemental Indenture”), dated as of
                , among                  (the “Guaranteeing
Subsidiary”), a subsidiary of SBA COMMUNICATIONS CORPORATION (or its permitted successor), a Florida corporation (the “Company”), the Company, the other Subsidiary Guarantors (as defined in the Indenture referred to herein) and U.S.
BANK NATIONAL ASSOCIATION, as trustee under the Indenture referred to below (the “Trustee”). 
  
 W I T N E S S E T H 
  
 WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of December 14, 2004 providing for the issuance of an aggregate principal amount of up to
$250,000,000 of 81⁄2 % Senior Notes due 2012 (the “Notes”); 
  
 WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall
unconditionally guarantee all of the Company’s Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and 
  
 WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is 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 Guaranteeing Subsidiary 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. Agreement to Guarantee. The Guaranteeing Subsidiary hereby agrees as follows: 
  

	 	(a)	Along with all other Subsidiary Guarantors, to jointly and severally Guarantee 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: 

  

	 	(i)	 the principal of and interest 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 and interest on the Notes, if any, if lawful, and all other obligations of the 

  

 E-1 

	 	 
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 

  

	 	(ii)	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 Subsidiary Guarantors shall be
jointly and severally obligated to pay the same immediately. 

  

	 	(b)	The 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. 

  

	 	(c)	The following is hereby waived: 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. 

  

	 	(d)	This Note Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and the Indenture. 

  

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

  

	 	(f)	The Guaranteeing Subsidiary 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. 

  

	 	(g)	 As between the Subsidiary Guarantors, 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 Note 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 

  

 E-2 

	 	 
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 Subsidiary Guarantors for the purpose of this Note Guarantee. 

  

	 	(h)	The Subsidiary Guarantors shall have the right to seek contribution from any non-paying Subsidiary Guarantor so long as the exercise of such right does not impair the rights of the
Holders under the Guarantee. 

  
 3. Execution and
Delivery. Each Guaranteeing Subsidiary agrees that the Note Guarantees shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. 
  
 4. Guaranteeing Subsidiary May Consolidate, Etc. on Certain Terms.

  

	 	(a)	In case of any consolidation or merger of the Guaranteeing Subsidiary with another corporation, Person or entity, and upon the assumption by the successor corporation, by
supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of the Indenture to be
performed by the Subsidiary Guarantor, such successor corporation shall succeed to and be substituted for the Subsidiary Guarantor with the same effect as if it had been named herein as a Subsidiary Guarantor. Such successor corporation thereupon
may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Note Guarantees so issued shall in all
respects have the same legal rank and benefit under the Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of the Indenture as though all of such Note Guarantees had been issued at the date of the
execution hereof. 

  

	 	(b)	Except as set forth in Articles 4 and 5 of the Indenture, and notwithstanding clause (a) above, nothing contained in the Indenture or in any of the Notes shall prevent any
consolidation or merger of a Subsidiary Guarantor with or into the Company or another Subsidiary Guarantor, or shall prevent any sale or conveyance of the property of a Subsidiary Guarantor as an entirety or substantially as an entirety to the
Company or another Subsidiary Guarantor. 

  
 5. No
Recourse Against Others. No past, present or future director, officer, employee, incorporator, stockholder or agent of the Guaranteeing Subsidiary, as such, shall have any liability for any obligations of the Company or any Guaranteeing Subsidiary
under the Notes, any Note Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all
such liability. The waiver and release are part of the 

  

 E-3 

 
consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the
SEC that such a waiver is against public policy. 
  
 6. NEW
YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE. 
  
 7. 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. 
  
 8. Effect of
Headings. The Section headings herein are for convenience only and shall not affect the construction hereof. 
  
 9. The Trustee. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary and the Company. 
  

 E-4 

 IN WITNESS WHEREOF, the parties hereto have caused this Supplemental Indenture to be duly executed and
attested, all as of the date first above written.

 [FORM OF REVERSE OF NOTES]

  
 81⁄2% Senior Notes due 2012 
  
 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 81⁄2% per annum from December 14, 2004 until maturity. The Company will pay
interest semi-annually in arrears on June 1 and December 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”); provided that the first such interest payment date
shall be June 1, 2005. Interest on the Notes will accrue from the most recent date on which interest has been paid or, if no interest has been paid, from December 14, 2004. 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 a rate that is 1% per annum in excess of 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 (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve
30-day months. 
  
 2. Method of Payment. The Company will
pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the May 15 or November 15 next 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 with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, Additional
Interest, if any, and interest at the office or agency of the Company maintained for such purpose within or without the City and State of New York, or, at the option of the Company, payment of interest 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 will be required with respect to principal of and interest and Additional Interest and premium on, all 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 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, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or
any of its Restricted Subsidiaries may act in any such capacity. 
  
 4. Indenture. The Company issued the Notes under an Indenture dated as of December 14, 2004 (“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 Notes are 

  

 
subject to all such terms, and Holders are referred to the Indenture and such Act 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 aggregate principal amount of Notes issuable under the Indenture is unlimited, although the issuance of Initial Notes will
be limited to $250,000,000 in aggregate principal amount. 
  
 5.

PART, UPON NOT LESS THAN 30 NOR MORE THAN 60 DAYS’ NOTICE AT THE REDEMPTION PRICES (EXPRESSED AS PERCENTAGES OF PRINCIPAL AMOUNT) SET FORTH BELOW PLUS ACCRUED AND UNPAID INTEREST AND ADDITIONAL INTEREST, IF ANY, TO THE APPLICABLE REDEMPTION

 (C) NOTWITHSTANDING

OF SUCH REDEMPTION (EXCLUDING NOTES HELD BY THE COMPANY OR ANY OF ITS SUBSIDIARIES); AND PROVIDED, FURTHER, THAT SUCH REDEMPTION SHALL OCCUR WITHIN 60 DAYS
OF THE DATE OF THE CLOSING OF SUCH EQUITY OFFERING AND/OR STRATEGIC EQUITY INVESTMENT. 
  
 6. Mandatory Redemption. Except as set forth in paragraph 7 below, the Company shall not be required to make mandatory redemption payments with respect to the Notes. 
  
 7. Repurchase at Option of Holder. 
  
 (a) Upon the occurrence of a Change of Control, each Holder of Notes shall
have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”) at an offer price in
cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest, if any (subject to the right of Holders of record on the relevant record date to receive interest and Additional Interest, if any,
due on the relevant interest payment date), to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company shall mail a notice to each Holder setting forth the procedures governing
the Change of Control Offer as required by the Indenture. 
  
 (b)
If the Company or a Restricted Subsidiary consummates any Asset Sales, when the aggregate amount of Excess Proceeds exceeds $10 million, the Company or the applicable Restricted Subsidiary shall commence an offer pursuant to Section 3.09 of the
Indenture (an “Asset Sale Offer”) to all Holders of Notes and all holders of other Senior Indebtedness excluding the 2011 Notes, containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem
with the proceeds of sales of assets (such other Senior Indebtedness, the “Pari Passu Notes”) to purchase the maximum principal amount (or accreted value, as applicable) of Notes and such Pari Passu Notes that may be purchased out of the
Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount (or accreted value, as applicable) thereof plus accrued and unpaid interest thereon and Additional Interest, if any, to the date of purchase (subject to
the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date), in accordance with the procedures set forth in the Indenture and the instruments governing such Pari Passu Notes. To the
extent that any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount (or accreted value, as
applicable) of Notes and Pari Passu Notes tendered into such Asset Sale Offer surrendered by Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and Pari Passu Notes to be purchased on a pro rata basis based on
the aggregate principal amount (or accreted value, as applicable) of Notes and Pari Passu Notes tendered. Upon completion of such offer to purchase, the amount of Excess Proceeds shall be reset to zero. Holders of Notes that are the subject of an
offer to purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” on the reverse of the
Notes. 
  

 8. Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60
days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a
Holder are to be redeemed. On and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption. 
  
 9. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000.
The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may
require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any
Note being redeemed in part. Also, the Registrar need not exchange or register the transfer of any Notes for a period of 15 Business Days before a selection of Notes to be redeemed or during the period between a record date and the corresponding
Interest Payment Date. 
  
 10. Persons Deemed Owners. The
registered Holder of a Note may be treated as its owner for all purposes. 
  
 11. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority of the aggregate principal
amount of the then outstanding Notes voting as a single class, and any existing default or compliance with any provision of the Indenture or the Notes (other than a default in the payment of the principal of, premium, if any, or interest or
Additional Interest on the Notes) may be waived with the consent of the Holders of at least a majority of the aggregate principal amount of the then outstanding Notes voting as a single class. Without the consent of any Holder of a Note, the
Indenture or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s
obligations to Holders of the Notes in case of a merger or consolidation, to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture, to make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder, or to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the
Trust Indenture Act. 
  
 12. Defaults and Remedies. Events
of Default include: (i) default for 30 days in the payment when due of interest or Additional Interest on the Notes; (ii) default in payment when due of principal of or premium, if any, on the Notes when the same becomes due and payable at maturity,
upon redemption (including in connection with an offer to purchase) or otherwise, (iii) failure by the Company to comply with Section 4.10, 4.15 or 5.01 of the Indenture; (iv) failure by the Company to observe or perform any other covenant,
representation, warranty or other agreement in the Indenture or the Notes for 30 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the 

  

 
Notes then outstanding voting as a single class; (v) default under certain other agreements relating to Indebtedness of the Company or any of its Significant
Subsidiaries which default (a) is caused by a failure to pay principal of or premium, if any, or interest on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (“Payment
Default”) or (b) results in the acceleration of such Indebtedness prior to its Stated Maturity and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness under which there has
been a Payment Default or the maturity of which has been so accelerated, aggregates to $10.0 million or more; (vi) certain final judgments for the payment of money that remain undischarged for a period of 60 days provided that the aggregate of all
such undischarged judgments exceeds $10.0 million; and (vii) certain events of bankruptcy or insolvency with respect to the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary. If any Event of Default occurs and is
continuing, the Trustee, by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Notes, by notice to the Company, may declare all the Notes to be due and payable. Notwithstanding the foregoing, in the
case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the
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. The Trustee may withhold from Holders of the Notes notice of any
continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of
the Notes then outstanding by written notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in
the payment of interest or premium or Additional Interest on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming
aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 
  
 13. 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. 
  
 14. No Recourse Against Others. Any past, present or future director, officer, employee, incorporator or stockholder, of the Company, as such,
shall not have any liability for any obligations of the Company under the Notes or the Indenture, the Registration Rights Agreement or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by
accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. 
  
 15. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an Authenticating Agent. 

 
 16. Abbreviations. Customary abbreviations may be used in the name
of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the 

  

 
entirety), JT TEN (= joint tenants with rights of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors
Act). 
  
 17. Additional Rights of Holders of Restricted Global
Notes and Restricted Definitive Notes. In addition to the rights provided to Holders of Notes under the Indenture, Holders of Restricted Global Notes and Restricted Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of December 14, 2004, between the Company and Initial Purchasers. 
  
 18. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may
use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon. 
  
 The Company will
