ON OCTOBER 8, 2001, AT&T WIRELESS ISSUED THE FOLLOWING PRESS RELEASE:


FOR RELEASE 10/8/2001

AT&T WIRELESS TO ACQUIRE TELECORP PCS TWENTY
PERCENT EXPANSION OF FOOTPRINT INCLUDES 16 OF TOP 100
U.S. MARKETS


Redmond, WA and Arlington, VA -- AT&T Wireless (NYSE: AWE) announced today that
it will acquire TeleCorp PCS (NASDAQ: TLCP) in an all-stock transaction valued
at $4.7 billion. AT&T Wireless will acquire the 77 percent of the company it
does not already own for $2.4 billion and assume $2.1 billion in net debt and
approximately $221 million in preferred securities.

The boards of directors of both companies have approved the transaction and
TeleCorp PCS shareowners representing a majority of the voting power have
committed to vote in favor of the acquisition.

AT&T Wireless said it will offer TeleCorp PCS shareowners 0.9 shares of AT&T
Wireless common stock for each share of TeleCorp PCS common stock. This
represents a premium of 19 percent based on the average of the closing prices
for the past 30 trading days for TeleCorp PCS common stock. AT&T Wireless, which
currently owns 23 percent of TeleCorp PCS, will issue approximately 146 million
additional common shares to acquire the remaining outstanding TeleCorp PCS
common shares. Following the close of the acquisition, AT&T Wireless would have
approximately 2.68 billion common shares outstanding. The transaction is
structured to be tax-free to TeleCorp PCS shareowners.

"Strategically, this is the single most important move we could make to enhance
long-term shareowner value," said AT&T Wireless Chairman and CEO John D. Zeglis.
"We're set to quickly roll out AT&T Wireless-branded services to 32 million more
people across 14 states. That includes 16 of the top 100 U.S. markets, eight of
the top 50 markets and more than 900,000 existing TeleCorp customers. Soon, we
will be offering millions of potential new customers a full array of AT&T
Wireless' popular local, regional and national offers.

"Just as important, we'll include these new markets as part of our integrated
build out of a world-standard next generation network," he said. "TeleCorp
customers will enjoy the benefits of these exciting new advanced services sooner
than anticipated and under the AT&T Wireless brand.

"This is a strategically and financially attractive transaction for both
companies," Zeglis added. "For AT&T Wireless, it makes good use of our equity
while enabling us to maintain a strong balance sheet. TeleCorp shareowners will
receive a fair premium and a good growth investment."

"We are very proud of everything TeleCorp has accomplished over the last several
years," said TeleCorp CEO Jerry Vento. " The company has just completed a very
successful third quarter, reporting total subscribers of more than 914,000.





"AT&T Wireless is a well-managed company with a very strong balance sheet, and
we believe its shares are currently undervalued," he added. "We believe this
transaction is in the best interests of the shareholders of both companies."

Both companies said they expect the transaction to close in the first half of
2002, following approval from Telecorp PCS shareowners and approvals from the
Federal Communications Commission and Department of Justice. The companies do
not anticipate significant regulatory issues given that the proposed transaction
will result in a minimal overlap of markets.

AT&T Wireless will be adding markets covering a population of about 32 million
in 14 states -- primarily in the Southeast and Midwest including such markets as
New Orleans, Nashville, Memphis and Louisville -- as well as the commonwealth of
Puerto Rico. The company said it will be paying approximately $154 per licensed
POP or $180 per covered POP. This compares favorably to AT&T Wireless' current
valuation of $182 per licensed POP and $237 per covered POP.

Merrill, Lynch & Co. served as financial advisor and Wachtell, Lipton, Rosen &
Katz served as legal advisor to AT&T Wireless. Lehman Brothers and J.P. Morgan
Chase served as financial advisors, and Cadwalader, Wickersham &Taft served as
legal advisor to TeleCorp PCS.

detailed presentation about this transaction, including U.S. footprint maps,
both before and after the transaction is finalized.
