TO
SENIOR UNSECURED TERM PROMISSORY NOTE

     THIS FIRST AMENDMENT TO SENIOR UNSECURED TERM PROMISSORY NOTE, entered into on October 7, 2005, but in all regards intended to be effective as of August 2, 2005 (this “Amendment”), is made to the Senior Unsecured Term Promissory Note dated August 2, 2005 (the “Original Note”), in the original principal amount of $2.5 billion, executed by Clear Channel Outdoor, Inc. a Delaware corporation (“Maker”), as maker thereof, originally payable to the order of Clear Channel Outdoor Holdings, Inc., a Delaware corporation (“CCO”), transferred, by endorsement, by CCO to Clear Channel Holdings, Inc., a Delaware corporation (“Holdings”), and subsequently transferred, by endorsement, by Holdings to Clear Channel Communications, Inc., a Texas corporation (“CCU”).

     Recitals. CCU, as the current legal and equitable owner and holder, and the payee, of the Original Note, and Maker desire to amend the Original Note (i) to exclude ab initio from its mandatory prepayment requirements the equity issuance contemplated by the initial public offering of CCO and (ii) to clarify that certain borrowings under the Credit Facility will not require a mandatory prepayment on the Note. Now, therefore, in consideration of the premises, covenants and agreements herein contained, and for other good and valuable consideration, the receipt, sufficiency and reasonably equivalent value of which are acknowledged by the parties hereto, Maker and CCU agree as follows:

     SECTION 1. Definitions. Capitalized terms used but not defined herein have the meanings and uses assigned in the Original Note, and the term “Note” when used in this Amendment means the Original Note, as amended hereby.

     SECTION 2. Amendments.

     2.1. The term “Debt Issuance” as defined and used in the Original Note is hereby amended in its entirety to read as follows:

     SECTION 3. Representations and Warranties.

Each of the Original Note and the other Subject Documents, as amended hereby, is hereby ratified and confirmed in all respects, and all references to the “Note” in the Original Note or any other Subject Document shall mean the Original Note, as amended hereby. This Amendment shall not constitute an amendment of, or waiver with respect to, any provision of the Original Note not expressly referred to herein and shall not be construed as an amendment, waiver or consent to any action on the part of any party hereto that would require an amendment, waiver or consent of CCU except as expressly stated herein.

     SECTION 7. Counterparts. This Amendment may be executed in any number of counterparts, and by each party hereto on separate counterparts, each of which counterpart when so executed shall be an original, but all such counterparts taken together shall constitute one and the same instrument.
