                             ---------------------

                        SBA COMMUNICATIONS CORPORATION
            To ACQUIRE UP to 275 TOWERS and ENTER INTO an EXCLUSIVE
                  `BUILD-to-SUIT' AGREEMENT with TeleCorp PCS

SBA COMMUNICATIONS CORPORATION (NASDAQ: SBAC - news), a leading communications
tower developer and owner and TeleCorp PCS, Inc. (Nasdaq: TLCP - news), AT&T
                                                          ----   ----
Wireless' largest affiliate, announced today that SBA will acquire between 213
and 275 existing TeleCorp towers and become the exclusive build-to-suit provider
for TeleCorp PCS for a minimum of 200 and up to a maximum of 400 new towers.

The existing towers are located in TeleCorp's markets in Louisiana, Tennessee,
Mississippi, Missouri, Arkansas and Puerto Rico. SBA will pay TeleCorp $327,500
per tower, and TeleCorp will lease back space on the towers for an initial
monthly rental fee of $1,200 per site under a long term lease agreement, with
increases in subsequent years. The towers also currently produce approximately
$1.5 million in annualized rental revenues from other tenants.

Under the build-to-suit agreement, a minimum of 200 tower facilities will be
constructed for SBA's ownership across TeleCorp PCS' future service area -
Louisiana, Mississippi, Puerto Rico, Arkansas, Texas, Tennessee, Kentucky,
Missouri, Indiana, Illinois, Iowa, Michigan and Wisconsin - over the next three
years, pending the approval of its acquisition of properties in Iowa and
Wisconsin. TeleCorp will execute long term leases to place its wireless network
equipment at each site and pay SBA an initial monthly rental fee of $1,300 per
site, with increases in subsequent years. The first 200 tower facilities will be
built under the new agreement, and up to 200 additional tower facilities may be
constructed under the build-to-suit agreement previously announced by SBA on
April 26, 2000.

The tower acquisition is subject to due diligence and other contingencies, and
is anticipated to be completed early in the first quarter of 2001. The new
build-to-suit agreement is contingent on the closing of the tower acquisition.

"We are pleased to expand our relationship with TeleCorp," said Steven
Bernstein, chairman and CEO of SBA. "We were attracted to the portfolio because
TeleCorp's towers are very similar to the towers we have been building for SBA -
newly-constructed, well-located, multi-tenant capable and engineered for today's
PCS, digital and data users. In TeleCorp, we are fortunate to have as our
partner a very dynamic, high-growth carrier to whom we are committed to help
develop their network," concluded Bernstein.

"We have been very pleased with our existing relationship with SBA, and we look
forward to expanding it through this new build-to-suit agreement and sale of
towers, "said Gerald T. Vento, chairman and CEO of TeleCorp. "The sale of these
tower assets provides us with additional capital as we continue to focus on our
core business. We also have the security and confidence that our future sites
will be ready on time and on budget."
