HELLENIC TELECOMMUNICATIONS ORGANIZATION S.A.

OTE announces intention to delist from the NYSE

• Move aimed at reducing costs and concentrating trading on most

liquid market

• Continued commitment to highest standards of corporate

governance and financial disclosure

Athens, Greece – May 12, 2010 - Hellenic Telecommunications Organization SA

(ASE: HTO; NYSE: OTE) today announced that it intends to delist its American

Depositary Receipts ("ADRs") from the New York Stock Exchange ("NYSE") and to

deregister and terminate its reporting obligations under the Securities Exchange

Act of 1934 ("the Exchange Act"). OTE's Board of Directors approved the decision

at its meeting yesterday. OTE expects the delisting and deregistration to become

effective within the second half of 2010.

OTE’s decision to delist from the NYSE is aimed at cutting administrative costs,

reducing complexity in financial reporting, and concentrating trading of its shares

on the market providing the highest liquidity, the Athens Stock Exchange. OTE

remains committed to serve its investor base in the US, to comply with the highest

standards of corporate governance, and to provide comprehensive and transparent

English-language financial reporting.

OTE will provide written notice to the NYSE of its intention to delist. OTE also

intends to file the related Form 25 with the SEC. Once the delisting has become

effective and the Company meets the criteria for deregistration, it intends to file

Form 15F with the SEC in order to deregister its equity securities.

OTE intends to maintain an American Depositary Receipt program on a so-called

"Level I" basis in order to enable investors to trade ADRs in the US over-thecounter

(OTC) market.

OTE reserves the right, for any reason, to delay these filings or to withdraw them

prior to their effectiveness, and to otherwise change its plans in this regard.
