Telefónica de Argentina to delist 8.850% Senior Notes due August 1, 2011

(CUSIP No. 879378AK3) from the New York Stock Exchange

Telefónica de Argentina S.A. (“TASA”) today notified the New York Stock Exchange (the “NYSE”) of its intention to delist its 8.850% Senior Notes due August 1, 2011 (CUSIP No. 879378AK3) (the “2011 Notes”) from the NYSE and terminate the registration of the 2011 Notes with the Securities and Exchange Commission (the “SEC”) under the Securities Exchange Act of 1934, as amended (the “1934 Act”).

Telefónica, S.A., following its acquisition of all minority interests pursuant to Decree No. 677/01 in January 2010, currently owns, indirectly, 100% of TASA’s shares, which have been withdrawn from listing on the Buenos Aires Stock Exchange and the NYSE and deregistered under the 1934 Act. On November 8, 2010, the 2011 Notes will be TASA’s sole series of securities outstanding in the U.S. market. Further, TASA’s management has concluded that there are a relatively small number of global holders of the 2011 Notes, of which only a small minority are resident in the United States, and that the trading volume of the 2011 Notes on the NYSE is low.

Based on the foregoing, TASA’s Board of Directors, at its August 5, 2010 meeting, determined that the small number of holders and low level of U.S. resident holdings do not justify the expenses associated with being a listed and registered company in the United States, and agreed to delist the 2011 Notes from the NYSE and deregister them under the 1934 Act, following the completion of all required legal steps. TASA intends to effect the delisting by filing a Form 25 with the SEC on or about August 23, 2010, and expects that the last day of trading of the 2011 Notes on the NYSE will be September 1, 2010. TASA intends to terminate its reporting obligations with the SEC soon thereafter.

TASA has not arranged for the listing of 2011 Notes on any other national exchange in the United States or in any other country or for the quotation of the 2011 Notes in any quotation medium. Given the small number of holders, the low NYSE liquidity and the relatively short time to maturity of the 2011 Notes, TASA expects that trading on an over-the-counter basis will satisfy bondholder needs.

TASA will continue making information available to bondholders through its corporate website (http://www.telefonica.com.ar/), including English-language annual reports containing financial statements reconciled to U.S. Generally Accepted Accounting Principles. Such annual reports will also be provided to the trustee pursuant to the Indenture governing the 2011 Notes. TASA believes that this is sufficient to satisfy bondholder expectations.
