             IRIDIUM REPORTS FIRST QUARTER RESULTS (NASDAQ: IRID)

WASHINGTON, D.C. -- Iridium LLC today announced revenues for the first quarter
ending March 31, 1999 of $1, 451,000.00, and a net loss of $505 million, or
$3.45 loss per Class 1 Interest. To partially offset substantially lower than
anticipated revenues, Iridium is reducing expenses in areas not essential to
generating increased revenues. The details of the financial results are shown in
the accompanying table. As of March 31, there were approximately 10,294
customers on the Iridium system, including 7,188 satellite-homed voice
customers, 1,031 cellular-homed voice customers and 2,075 satellite paging
customers.

The Company is in the early stages of its transition from development to
commercialization stage, and many of the customers included in the current
results may be, or may have been during the reporting period, in a mode of
evaluation and test of the Iridium services. Furthermore, the Company believes
that the reported results reflect that periods as long as several weeks can
normally be encountered from the date of customer activation, which these
results report, and the actual usage of the services by such customers.

Iridium's efforts to attract customers were hindered by a number of factors
during the period, notably, limited availability of some handset models and
accessories in many markets, and delays by the overall Iridium distribution
network to field sufficient numbers of properly trained and equipped
salespeople. With the commencement of handset shipments by Kyocera Corporation
late in the quarter, and with Motorola now shipping virtually all Iridium
accessories, production by the manufacturers is now adequate, although a number
of distribution and importation issues continue to constrain actual product
availability in many markets.

"Although we have succeeded in building a network that is providing high-quality
service to our customers, we were very disappointed with our first quarter
customer and revenue numbers," said John A. Richardson, Iridium's interim CEO.
"Clearly, we have a great deal of work to do to improve our marketing,
distribution and sales activities all over the world. Over the course of the
first quarter, we have identified major causes for the poor sales 
   4



performance, and are initiating aggressive actions in response, acting in
concert with our regional Gateway partners, our equipment suppliers, and the
outstanding roster of service providers and roaming partners they have
enlisted."

Iridium LLC, its gateway partners, and its equipment suppliers are initiating a
number of significant actions to address the sales shortfall, including:
tailoring the Iridium product and service offering to better fit the identified
market demand, accelerating introduction of Iridium products and services by the
types of distribution channel that have proven to be the most effective to date,
and reconsideration of product and service prices.
