ITEM 5.           INTEREST IN SECURITIES OF THE ISSUER

     The information contained in Item 5 of the Schedule 13D is hereby amended
and supplemented by adding the following information:

     On August 23, 2005, Mr. Diller exercised options to acquire 1,895,847
shares of Common Stock at an exercise price of $6.29 per share. In connection
with the foregoing stock option exercise, IAC withheld 471,433 shares of Common
Stock to cover the payment of the aggregate exercise price and IAC withheld
709,149 shares of IAC Common Stock for payment of aggregate taxes due, such
withheld shares of Common Stock having a fair market value of $25.30 per share.

     On November 22, 2005, Mr. Diller exercised options to acquire 6,381,250
shares of Common Stock at an exercise price of $5.25 per share. In connection
with the foregoing stock option exercise, IAC withheld 1,157,222 shares of
Common Stock to cover the payment of the aggregate exercise price and IAC
withheld 2,600,797 shares of IAC Common Stock for payment of aggregate taxes
due, such withheld shares of Common Stock having a fair market value of $28.95
per share.

     On November 22, 2005, Mr. Diller exercised options to acquire 1,250,000
shares of Common Stock at an exercise price of $8.54 per share. In connection
with the foregoing stock option exercise, IAC withheld 372,796 shares of Common
Stock to cover the payment of the aggregate exercise price and IAC withheld
436,719 shares of IAC Common Stock for payment of aggregate taxes due, such
withheld shares of Common Stock having a fair market value of $28.635 per share.

     After giving effect to the exercise of options by Mr. Diller described
above, the members of the Reporting Group beneficially own 58,726,078 shares of
Common Stock (assuming the exercise of options to purchase 9,500,000 shares of
Common Stock which are currently exercisable by Mr. Diller) and 25,599,998
shares of Class B Common Stock, which shares constitute 20.0% of the outstanding
shares of Common Stock and 100% of the outstanding shares of Class B Common
Stock. Assuming the conversion of all of the Reporting Group's shares of Class B
Common Stock into Common Stock, the Reporting Group would beneficially own 25.4%
of the outstanding Common Stock (calculated in accordance with Rule 13d-3).
Because each share of Class B Common Stock generally is entitled to ten votes
per share, each share of Common Stock is entitled to one vote per share and each
share of outstanding preferred stock is entitled to two votes per share, the
Reporting Persons may be deemed to beneficially own equity securities of the
Company representing approximately 56% of the voting power of the Company. The
foregoing beneficial ownership amounts exclude shares of Common Stock
beneficially owned by the executive officers and directors of Liberty and shares
of Common Stock beneficially owned by Diane Von Furstenberg, Mr. Diller's
spouse, as to which Mr. Diller disclaims beneficial ownership. Subject to
adjustment in accordance with Rule 13d-3, the foregoing beneficial ownership
amounts are based on there being outstanding as of the close of business on
October 28, 2005 293,780,991 shares of Common Stock, 25,599,998 shares of Class
B Common Stock and 846 shares of preferred stock, which share numbers were
disclosed in the Company's quarterly report on Form 10-Q filed on November 9,
2005. Mr. Diller continues to hold an irrevocable proxy granted by Liberty,
pursuant to which Mr. Diller has the right to vote the Company's securities held
by Liberty and its affiliates, subject to certain limitations.
