                       Items to be Included in this Report

Item 3.02. UNREGISTERED SALES OF EQUITY SECURITIES

On May 20, 2006, Clear Channel Outdoor Holdings, Inc., a Delaware corporation
("CCO"), entered into a Stock Purchase Agreement (the "PURCHASE AGREEMENT") by
and among CCO, Clear Channel Outdoor, Inc., a Delaware corporation and
wholly-owned subsidiary of CCO ("BUYER"), IN-TER-SPACE Services, Inc., a
Pennsylvania corporation ("ISI"), and the shareholders of ISI (the
"SHAREHOLDERS"), pursuant to which Buyer will purchase, and the Shareholders
will sell to Buyer, all of the issued and outstanding capital stock of ISI.
Under the terms of the Purchase Agreement, the purchase price for such capital
stock of ISI will be approximately $94.5 million, subject to certain working
capital and other adjustments, plus (i) 4,250,000 shares of Class A Common Stock
(the "SHARES"), par value $0.01, of CCO, and (ii) an earn-out provision for
additional consideration, 51% of which will be payable in additional shares of
Class A Common Stock of CCO (the "EARN-OUT SHARES"), valued based on a 15-day
closing average prior to March 31 of the year following the fiscal year in
respect of which the Earn-Out Shares are issued, and 49% of which will be
payable in cash. Payments under the earn-out provision will be based on ISI
achieving certain earnings performance targets for the fiscal years 2006 through
2010. At the closing, the initial $94.5 million, subject to the referenced
adjustments, will be paid to the Shareholders in cash and funded from CCO's cash
on hand and the Shares will be issued to the Shareholders, with a portion of
such Shares being delivered into an escrow account to be used to offset any
amounts owed to CCO or Buyer pursuant to indemnity provisions of the Purchase
Agreement. The purchase transaction is subject to customary closing conditions,
including regulatory approval, and is expected to be completed in the third
quarter.

CCO anticipates that the issuance of the Shares and the Earn-Out Shares, if any,
pursuant to the Purchase Agreement will be exempt from the registration
requirements of the Securities Act of 1933, as amended, pursuant to Section 4(2)
thereof and Regulation D promulgated thereunder, based upon representations that
CCO has obtained, or will obtain prior to issuance, from each Shareholder
receiving such Shares or Earn-Out Shares, if any, that the Shareholder is an
"accredited investor" as such term is defined in Rule 501(a) of Regulation D.

Pursuant to the terms of a stock transfer restriction and registration rights
agreement to be signed at the closing of the purchase transaction between CCO
and the Shareholders, the principal Shareholders will agree to certain
restrictions on the sale of their CCO Class A Common Stock, will be granted
"piggy back" registration rights and CCO will agree, upon the occurrence of
certain events, to file a registration statement with the Securities and
Exchange Commission to register the Shares and the Earn-Out Shares, if any, for
resale. A copy of the form of stock transfer restriction and registration rights
agreement is attached hereto as Exhibit 4.1 and is incorporated herein by
reference.

A copy of the press release announcing the execution of the Purchase Agreement
is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
