            THE TELECOMMUNICATION AUTHORITY FINES TURKCELL REGARDING

Special Subjects:

The Telecommunication Authority ("TA") has fined Turkcell, claiming that
Turkcell has not complied with its responsibility under Turkish regulations to
provide national roaming. The fine totals TL21,822,150,300,000 (approximately
US$16.7mn as of April 1, 2004). Roaming allows other operators' subscribers to
use Turkcell's networks when they are outside the reach of their own operator's
network.

Turkcell will take the necessary legal actions against the TA's ruling.
