UPDATE 2-Clear Channel says buyout may collapse

(Adds details from analyst note, share movement)

NEW YORK, March 28 (Reuters) - U.S. radio broadcaster Clear Channel Communications Inc (CCU.N) said on Friday its pending $20 billion buyout may collapse, as the banks had failed to provide funding for the deal under previously agreed terms.

In a filing with the Securities and Exchange Commission, Clear Channel said it had agreed with buyout firms Thomas H. Lee Partners LP and Bain Capital Partners LLC that all closing conditions for the deal have been satisfied.

"The company continues to be ready, willing and able to consummate the merger under the merger agreement, which remains in effect," Clear Channel said in the filing. "The company is unable, however, to estimate a closing date at this time and cautions the markets that a closing may not occur," it added.

The deal had been expected to close March 31.

The comments are expected following events this week. The deal on Wednesday descended into litigation, with Clear Channel and the buyout firms suing the banks, alleging they balked at their obligation to fund the deal and hadn't stuck to previously agreed terms.

A spokeswoman for the banks said at the time the lawsuits were filed that they were without merit and would be contested vigorously.

Clear Channel's shares fell 5 percent to $28.09 on Friday on the New York Stock Exchange -- significantly below the $39.20 a share offered.

In a research note Friday, Miller Tabak analyst David Joyce wrote that Clear Channel is in "fine financial shape and is outperforming a weak radio industry."

The company would still be a desirable acquisition candidate if the deal collapses, or it could operate equally as well on its own, he wrote. Joyce has a price target of $39.20 on the shares.

Clear Channel's filing noted that while the parties met on Thursday, the six banks led by Citigroup Inc (C.N) didn't show up.

On Thursday, the U.S. radio operator was granted a temporary restraining order against the banks that also include Morgan Stanley (MS.N), Credit Suisse Group (CSGN.VX), Royal Bank of Scotland Group Plc (RBS.L), Deutsche Bank AG (DBKGn.DE) and Wachovia Corp WB.N. That prevents them temporarily from reneging on their funding commitments. They were to provide more than $22 billion in financing for the buyout.

The private equity firms filed the lawsuits in New York and Texas on Wednesday. Clear Channel joined in the Texas lawsuit. (Reporting by Jui Chakravorty; additional reporting by Megan Davies; editing by Jeffrey Benkoe)
