SBA Communications Corporation, a Florida corporation (the “Company”), promises to pay interest on the principal amount of this Note at 8½% 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.

The Notes are

subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms.

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.

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.
