                        CERTAIN FACTORS WHICH MAY AFFECT
                           FORWARD LOOKING STATEMENTS
 
     The following risk factors should be carefully considered by prospective
investors in Iridium World Communications Ltd., Iridium LLC or Iridium Operating
LLC. Iridium World Communications Ltd. acts as a member of Iridium LLC and has
no other business. The business of Iridium Operating LLC ("Iridium") constitutes
substantially all of Iridium LLC's business. The business of Iridium is
discussed below.
 
DEVELOPMENT STAGE COMPANY; ABSENCE OF REVENUES
 
     Iridium is a development stage enterprise with no operating history.
Prospective investors have no operating and financial data about the IRIDIUM
System on which to base an evaluation of the IRIDIUM System's performance or an
investment in IWCL, Parent or Iridium. Iridium expects to realize significant
net losses at least until some time after the IRIDIUM System commences
commercial operations, which is currently anticipated to be September 23, 1998.
The completion and maintenance of the IRIDIUM System and implementation of
commercial service will require significant additional expenditures of funds.
Iridium currently has no source of revenues other than nominal interest income.
No assurances can be given that, or when, the IRIDIUM System will become
commercially operational, or that, or when, Iridium will have revenues from
operations or become profitable.
 
SIGNIFICANT ADDITIONAL FUNDING NEEDS
 
     Iridium anticipates total cash funding requirements of approximately $4.4
billion through September 23, 1998, the date on which Iridium expects to
commence commercial operations, and $5.3 billion (net of assumed revenues
following commercial activation) through year-end 1999, the last year in which
Iridium projects negative cash flow and a net increase in year-end borrowings.
 
     Based on funds raised or conditionally committed as of March 1, 1998,
Iridium expects to have sufficient cash to meet its anticipated funding
requirements through September 23, 1998, the date on which Iridium expects to
commence commercial operations. Iridium expects to seek other senior secured
bank financing in order to meet its expected funding requirements through at
least year-end 1999, the last year in which Iridium projects negative cash flow
and a net increase in year-end borrowings. There can be no assurance, however,
that conditionally committed funds will be available to Iridium, or that any
such other bank financing will be obtained by Iridium on terms and conditions
acceptable to it, and, if any of such financing is unavailable, there can be no
assurance that Iridium will be able to obtain alternative financing on terms and
conditions acceptable to it. Iridium's estimated funding requirements do not
reflect any contingency amounts and therefore those requirements will increase,
perhaps substantially, in the event of unexpected cost increases or schedule
delays.
 
RISK OF HIGHLY LEVERAGED CAPITAL STRUCTURE
 
     Iridium is a development stage company with a highly leveraged capital
structure and expects to incur substantial additional indebtedness, including
secured indebtedness. The amount of debt needed to finance the IRIDIUM System
could be increased by one or more factors outside the control of Iridium,
including cost increases related to the acquisition of the IRIDIUM System, a
delay in the delivery date of the system, a failure of the demand for the
Iridium World Services to materialize as expected (or a delay in the development
thereof) and increases in prevailing market interest rates. Iridium currently
has no significant income-producing assets from which to service its
indebtedness.
 
     Iridium's current and future debt service requirements could have important
consequences to investors in IWCL, Parent or Iridium, including the following:
(i) Iridium's limited ability to obtain additional financing for future working
capital needs or for other purposes; (ii) a substantial portion of Iridium's
cash flow from operations will be dedicated to the payment of principal and
interest on its indebtedness, thereby reducing
<PAGE>   2
 
funds available for operations; and (iii) Iridium's greater exposure to adverse
economic conditions than competing companies that are not as highly leveraged.
In addition, the discretion of Iridium's management with respect to certain
business matters will be limited by covenants contained in its debt instruments.
Among other things, such covenants limit or prohibit Iridium and its
subsidiaries from incurring additional indebtedness, creating liens on their
assets, making certain loans, investments or guarantees, issuing preferred
stock, declaring or paying dividends and distributions, making certain asset or
stock dispositions and entering into transactions with affiliates and related
persons. Moreover, a failure to comply with the terms of any agreements with
respect to outstanding or additional financing could result in an event of
default under such agreements, which could result in the acceleration of the
related debt and acceleration of debt under other debt agreements that may
contain cross-acceleration or cross-default provisions.
 
POTENTIAL FOR DELAY AND COST OVERRUNS
 
     Iridium's business plan assumes the IRIDIUM System will commence commercial
operations on September 23, 1998. Motorola's construction schedule for the
satellites in the IRIDIUM System requires an unprecedented rate of satellite
assembly for commercial telecommunications systems. A significant delay in the
delivery of the satellites needed for the space segment would materially and
adversely affect Iridium's operations.
 
     A significant delay in the date the IRIDIUM System becomes fully
operational would harm the competitive position of Iridium by eroding the timing
advantages Iridium currently anticipates, would delay the generation of revenue
by Iridium and might significantly affect Iridium's ability to pay interest on,
and the principal of, its indebtedness.
 
     The operation of the IRIDIUM System is dependent on the successful
construction and operation of gateways and the timely availability of necessary
regulatory licenses and approvals. Iridium closely monitors the progress of each
gateway and currently expects that up to 12 gateways will be in operation with
voice functionality at the commencement of commercial operations. Iridium
expects paging functionality to be available at a portion of the gateways by
September 1998 with the remainder activated by October 1998. However, there can
be no assurance that one or more gateways will not fail to be completed by the
commencement of commercial operations, which could have a material adverse
effect upon Iridium. In particular, two gateways, the China gateway and the
Middle East-Africa gateway, are significantly behind schedule with equipment
procurement for their gateways.
 
     Prior to commencement of commercial operations, Iridium must develop and,
in conjunction with each of the gateway owners, integrate and test software
related to the operation of the IRIDIUM System, including the business support
systems. A significant delay in the development, deployment or implementation of
such software systems would have a material adverse effect on Iridium.
 
     Significant delay in the development, manufacture and sale of phones and
pagers would have a material adverse effect on Iridium. Because there is no
current market for Iridium World Services and subscriber equipment, the
financial incentive for manufacturers to produce significant quantities of
subscriber equipment in advance is limited. Moreover, there is a risk that
demand for Iridium World Services will not materialize in a timely manner.
 
TECHNOLOGY AND TECHNOLOGY IMPLEMENTATION RISKS; INABILITY TO FULLY TEST PRIOR TO
SPACE DEPLOYMENT
 
     To build the IRIDIUM System, Motorola and its subcontractors must integrate
a number of sophisticated technologies. The integration of this array of diverse
technologies is a complex task which has not previously been attempted and is
further complicated by the fact that a significant portion of the hardware
components associated with the IRIDIUM System will be in space. Despite the
extensive testing of the components of the IRIDIUM System on the ground, the
nature and complexity of the system is such that final confirmation of the
ability of the system to function in the intended manner, including the ability
of the IRIDIUM System to handle the anticipated number of calls each day, cannot
be confirmed until a substantial portion of the system is deployed in space.
Errors involving hardware or software components in space may result in service
limitations and corresponding reductions in revenue.
<PAGE>   3
 
     Implementation and operation of the IRIDIUM System, including the business
support systems necessary for such tasks as customer billing and subscriber
authentication, are also significantly dependent on software which has been, is
being or will have to be developed, integrated and tested and which would have
to be reprogrammed if errors require changes. Iridium believes that the
development of the software for the IRIDIUM System, including the space segment,
is one of the largest and most complex software creation and integration tasks
ever undertaken in a commercial satellite communications program. No assurance
can be given that the software necessary to Iridium's business will be completed
when required, including integration and testing, or that such software will
function as required.
 
     The Iridium subscriber equipment is also an essential component critical to
the successful commercial operation of the IRIDIUM System. An inability to
successfully develop and manufacture subscriber equipment in sufficient numbers
could delay commencement of commercial operations or limit the capacity of the
system and the quality of services offered. Such limitations could affect
subscriber acceptance of Iridium World Services and as a result could materially
and adversely affect Iridium. There can be no assurance that Motorola or any
other manufacturer will be able to develop on a timely basis, or at all,
portable, hand-held phones or belt-worn pagers that meet Iridium's expectations
and which can be mass produced at economical prices.
 
CONSEQUENCES OF SATELLITE SERVICE LIMITATIONS ON CUSTOMER ACCEPTANCE
 
     Iridium's ability to generate sufficient operating revenues will depend
upon customer acceptance of and satisfaction with Iridium World Services, which
in turn will depend upon a variety of factors, including the price and technical
capabilities of the Iridium World Services and equipment, and the extent,
availability and price of alternative telecommunications services.
 
     Based upon current testing and simulations, Iridium subscribers using
Iridium World Satellite Services via portable, hand-held phones should expect
some degradation in service quality and availability to occur in environments
where obstructions, such as trees, buildings and other natural and man-made
obstacles, are positioned between a satellite and the user. The severity of this
degradation will increase as the obstacles become larger and more densely
spaced. Only extremely limited satellite voice service, or no satellite voice
service, is expected to be available in densely packed urban environments or
inside buildings with steel construction and metal coated glass common in many
urban high rise buildings (including, in particular, in most hotels and
professional buildings). In addition, because the structure of automobiles will
tend to obstruct the satellite signal, use of a hand-held Iridium phone in a
moving automobile will make the effect of environmental obstructions temporary
but more pronounced. The actual limitations will vary, sometimes significantly,
as actual situations and conditions change and as the satellites move across the
sky. The Iridium World Page Services will also be unable to provide service in
certain environments where terrestrial paging generally would. There can be no
assurance that (i) Iridium's expectation will be correct as to subscribers'
willingness to accept service limitations, higher prices and heavier hand-held
phones and larger pagers than those to which such subscribers may otherwise be
accustomed in order to have the ability to make and receive calls on a worldwide
basis with a single phone or to receive pages on a satellite pager or (ii) that
the service limitations will not result in significantly lower sales or lower
usage of Iridium World Services than Iridium anticipates.
 
     The IRIDIUM System has not been designed to provide high-speed data and
facsimile transmission capability. As a result, Iridium expects that the appeal
of Iridium facsimile and data services will be limited.
 
SATELLITE LAUNCH RISKS
 
     In order for the IRIDIUM System to be fully operational under its current
specifications and timetable, Iridium anticipates the need for Motorola to
successfully launch 21 additional satellites in five more launches by May 1998,
which would complete the expected constellation of 66 satellites in mission
orbit with four spare satellites in a lower parking orbit. Moreover, to maintain
the system, additional satellites are expected to be launched each year. No
other commercial satellite communications system has required this number of
launches to become fully deployed and operational. There can be no assurance
that Iridium's satellites will be
<PAGE>   4
 
successfully deployed in a timely manner or that launch failures will not occur
and materially and adversely affect Iridium. The risk of a material and adverse
effect associated with an Iridium launch failure is exacerbated by the fact that
each launch vehicle will contain multiple satellites.
 
  Impact of Excusable Delays
 
     The terms of the Space System Contract provide that Motorola will bear the
responsibility of launching the satellites that comprise the space segment.
Nevertheless, Iridium retains the risk of cost overruns and delays associated
with excusable delays, including delays in launch provider schedules due to
prior delays of launches of non-Iridium satellites, and the risk of economic
damage due to any delay or reduced performance beyond the limited remedies
provided by the Space System Contract.
 
LIMITED LIFE OF SATELLITES; COST OF MAINTAINING THE SPACE SEGMENT;
RISK OF SATELLITE FAILURE OR DAMAGE
 
     A significant portion of Iridium's tangible assets will be represented by
the satellites in the space segment. Iridium's business plan currently assumes
that the satellites will have a useful life of five years from their respective
launch dates. There can be no assurance that any satellite will actually achieve
such a useful life.
 
     Maintaining the space segment is a complex undertaking which has not
previously been attempted on a commercial basis. The cost of maintaining the
space segment and the risk of loss of satellites are significant. Iridium has
entered into an Operations and Maintenance Contract with Motorola which provides
for the operation and maintenance of the space segment for its first five years
of operation at an aggregate cost to Iridium of approximately $2.88 billion,
assuming the space segment is delivered in September 1998 and assuming no
excusable delay occurs. Iridium has the option to extend the Operations and
Maintenance Contract for an additional two years for additional aggregate
payments aggregating $1.33 billion (based on the same assumption) and assuming
no excusable delay occurs. Under the Operations and Maintenance Contract,
Iridium will bear the risk of damage to satellites by the acts of third parties
(including but not limited to the degradation or complete loss of any satellite
due to contact with space debris of any size or character). Satellites operating
in the low earth orbit region, such as the Iridium satellites, face a higher
risk of damage from space debris than satellites operating in geostationary
orbit.
 
     Motorola has experienced the loss of two of the 51 Iridium satellites
launched during the development of the IRIDIUM System. Premature failure or
interruption of one or more satellites, including temporary losses, that for
whatever reason are not promptly corrected or replaced, could, among other
things, cause gaps in service availability, significantly degrade service
quality, increase costs in the event Iridium is liable, and result in loss of
revenue for the period that service is compromised and, as a result, could
materially and adversely affect Iridium.
 
RISKS ASSOCIATED WITH LICENSING AND SPECTRUM ALLOCATION
 
     The operation of the IRIDIUM System is and will continue to be subject to
United States and international regulation. This regulation is pervasive and
largely outside Iridium's direct control. Iridium, Motorola and the various
gateway owners have made substantial progress in receiving the authorizations
necessary to operate the IRIDIUM System, but a significant number of regulatory
authorizations remain to be obtained, including (1) in each country in which a
gateway or system control terminal will be located, an authorization to
construct and operate those facilities, including necessary gateway link
spectrum assignments, (2) in each country in which Iridium subscriber equipment
will be operated, authority to market and operate that equipment with the
IRIDIUM System, user link spectrum assignments, and authorization to offer
Iridium communications services and (3) international coordination of the
IRIDIUM System under the auspices of the International Telecommunications Union
("ITU") or domestic coordination in each country where Iridium World Services
are offered with other entities using or proposing to use the spectrum required
for the IRIDIUM System or adjacent spectrum, to ensure the avoidance of harmful
interference.
<PAGE>   5
 
COMPETITIVE RISKS
 
     Certain sectors of the telecommunications industry are highly competitive
in the United States and in other countries. The uncertainties and risks created
by this competition are intensified by the continuous technological advances
that characterize the industry, regulatory developments which affect competition
and alliances between industry participants. While no single wireless
communications system serves the global personal communications market today,
Iridium anticipates that more than one system will serve this market in some
fashion in the future.
 
     Iridium's business plan assumes that Iridium will be able to charge a
global mobility premium, over the cost of a hypothetical terrestrial-based call,
for its Satellite Services. If the market will not support such a premium,
Iridium's ability to compete may be materially adversely affected. Also, the
IRIDIUM System will lack the operational capacity to provide local service to
large numbers of subscribers in concentrated areas and the IRIDIUM System will
not afford the same voice quality, signal strength and degree of building
penetration in areas that are served by mature terrestrial wireless voice or
paging systems.
 
RELIANCE ON MOTOROLA, GATEWAY OWNERS AND OTHER THIRD PARTIES
 
  Construction and Operation of the IRIDIUM System
 
     Iridium does not independently have and does not intend to acquire, except
by contracting with other parties, the ability to design, develop or produce the
components of the IRIDIUM System or to launch the constellation of satellites or
to operate and maintain the system once it is fully deployed. Motorola has
agreed to provide these services to Iridium under the Space System Contract, the
Operations and Maintenance Contract and the Terrestrial Network Development
Contract. Thus, Iridium currently relies on Motorola to perform these critical
tasks.
 
     Iridium has obtained commitments from its investors who are gateway
operators that they will use their reasonable best efforts to perform certain
critical functions including: obtaining the necessary licenses, if any, from the
jurisdictions in their gateway territories; constructing and operating the
gateways; connecting the IRIDIUM System to public switched telephone networks
("PSTNs"); marketing Iridium World Services; selecting, or acting as, service
providers; and managing relations with IRIDIUM System subscribers either
directly or through service providers. Iridium is dependent on the activities of
its gateway operators for its success. Some gateway operators are behind
schedule in the steps necessary to establish and implement their gateways. Other
gateway operators have indicated that they may not receive regulatory approvals
for some of the countries in their territories at the anticipated commencement
of commercial operations in September 1998. In particular, the China gateway and
the Middle East-Africa gateway are substantially behind schedule.
 
  Distribution and Marketing of Iridium World Services
 
     The sales of Iridium World Services and of Iridium subscriber equipment to
the ultimate consumer will be made by service providers which will be, or will
be selected by, Iridium's gateway operators. Iridium's business plan assumes
substantial sales of Iridium subscriber equipment by service providers prior to
the commencement of commercial services. Iridium's success will depend upon the
motivation and ability of such service providers to generate on a timely basis
demand for Iridium World Services and subscriber equipment, and there can be no
assurance that such demand can be generated on a timely basis. In addition,
Iridium may need to take a greater role than currently expected in connection
with the distribution of Iridium subscriber equipment. That increased
participation in the distribution process may require that Iridium incur
additional indebtedness or contingent purchase obligations relating to Iridium
subscriber equipment.
 
RISKS ASSOCIATED WITH PRINCIPAL SUPPLY CONTRACTS
 
  Space System Contract
 
     Iridium and Motorola are parties to the Space System Contract which
provides for the payment by Iridium to Motorola of $3.45 billion (subject to
certain adjustments) for the design, development, production and delivery in
orbit of the space segment. Furthermore, Motorola's aggregate liability under
the Space
<PAGE>   6
 
System Contract and related contracts with Iridium in the event the system is
not operational is subject to the Motorola Liability Limitations (defined below)
and in no event is Motorola required under the contract to refund amounts
previously paid by Iridium to Motorola. In addition, subject to certain
exceptions, Iridium bears the risk, including additional costs, if any,
resulting from excusable delays under the Space System Contract, as well as
certain of the risks of loss for satellites once placed in orbit.
 
     The Space System Contract provides that, to the extent Motorola has any
liability to Iridium under the contract for any costs, damages, claims or losses
whatsoever arising out of or related to such contract, or any such liability
under the Operations and Maintenance Contract, the Terrestrial Network
Development Contract or any other contract executed between Iridium and Motorola
in connection with the IRIDIUM System, or any provisions of any of the
foregoing, whether pursued as a breach of contract or as a tort or other cause
of action and whether accruing before or after completion of all the work
required under the contracts, such liability shall be limited to $100 million in
the aggregate (the "Motorola Liability Limitations").
 
  Operations and Maintenance Contract
 
     Iridium and Motorola are parties to the Operations and Maintenance
Contract, which obligates Motorola for a period of five years after completion
of the final milestone under the Space System Contract to operate the Iridium
space segment and to exert its best efforts to monitor, upgrade and replace the
hardware and software of the Iridium space segment as necessary to maintain
specified performance levels. Iridium has the right to extend the term of this
contract for an additional two years. This contract provides for specified
increasing quarterly payments by Iridium to Motorola that are expected to
aggregate approximately $2.88 billion, subject to certain adjustments.
 
     The Operations and Maintenance Contract contains provisions relating to
indemnification, excusable delays, insurance, permits and licenses, waivers of
rights, events of default and other matters similar to those contained in the
Space System Contract. Motorola's liability under the Operations and Maintenance
Contract is subject to the Motorola Liability Limitations. In the event that the
Space System Contract is terminated for whatever reason, the Operations and
Maintenance Contract will also terminate.
 
  Terrestrial Network Development Contract
 
     Iridium is also a party to the Terrestrial Network Development Contract
with Motorola, pursuant to which Motorola is obligated to design and develop the
gateway hardware and software, and license Iridium to use and permit others to
use intellectual property developed under the contract to procure the
development and manufacture of gateways from sources other than Motorola.
Motorola will be paid a total of approximately $284 million under the contract
in increments tied to the completion of milestones, including those relating to
acceptance tests of the completed gateway design. Motorola's liability under the
Terrestrial Network Development Contract is subject to the Motorola Liability
Limitations and the contract contains provisions relating to excusable delays,
waivers of rights, events of default and other matters similar to those
contained in the Space System Contract and the Operations and Maintenance
Contract.
 
RISK ASSOCIATED WITH INTERNATIONAL OPERATIONS AND DEVELOPING MARKETS
 
     Iridium expects that its telecommunications services will be available in
almost every country. As a result, Iridium and its gateway operators and service
providers will be subject to certain multinational operational risks, such as
changes in domestic and foreign government regulations and telecommunications
standards, licensing requirements, tariffs or taxes and other trade barriers,
price, wage and exchange controls, political, social and economic instability,
inflation, and interest rate and currency fluctuations. There can be no
assurance that Iridium, its gateway operators or service providers will not be
adversely affected by such multinational risks.
 
LIMITED SATELLITE CAPACITY
 
     To provide commercially adequate service, ensure user acceptance and
operate successfully, the IRIDIUM System will have to provide minimum levels of
availability of Iridium World Satellite Services,
<PAGE>   7
 
which will depend upon system capacity. Various factors, including usage
patterns, will have a significant impact on the capacity of the IRIDIUM System
for a particular geographic area and on a system-wide basis. Most important
among these are usage patterns and spectrum allocation. Iridium could experience
unexpected usage patterns which could exceed the capacity of the IRIDIUM System
through one or several gateways. If Iridium faces significant capacity issues,
its ability to increase its spectrum assignment in any market is subject to
significant regulatory hurdles. There can be no assurance that the necessary
spectrum assignments will occur or that adverse and unanticipated usage patterns
will not materialize. Failure to achieve a commercially viable capacity level
for any reason, including but not limited to those mentioned in this section,
would materially and adversely affect Iridium.
 
CONFLICTS OF INTEREST WITH MOTOROLA
 
     Motorola has and will have various conflicts of interest with Iridium.
Motorola is the creator and developer of the concept of the IRIDIUM System, the
principal supplier to Iridium, a founding investor of Iridium (through its
predecessors), a gateway owner, Iridium LLC's largest Class 1 Interest holder, a
holder of warrants to acquire Class 1 Interests and a warrant to acquire Series
M Class 2 Interests and the guarantor of Iridium's borrowings under its
Guaranteed Bank Facility.
 
     Although Motorola does not by itself control the Iridium Board and is not
permitted to participate in decisions or other actions by Iridium with respect
to the Space System Contract, Operations and Maintenance Contract and the
Terrestrial Network Development Contract, Motorola, through its position as (i)
the indirect holder of the largest ownership interest in Iridium, (ii)
potentially the largest holder of Class A Common Stock (through exchanges of
Class 1 Interests for shares of Class A Common Stock), (iii) the guarantor under
the Motorola Guarantee and, if issued, the Motorola Additional Guarantee and
(iv) the principal supplier to Iridium, could in certain situations exercise
significant influence over Iridium. For example, in addition to its
representation on the Iridium Board, Motorola could have control over Iridium as
or similar to that of a creditor through its position as a guarantor under the
Guaranteed Bank Facility.
 
     Motorola and Iridium entered into the Space System Contract, the Operations
and Maintenance Contract and the Terrestrial Network Development Contract after
extensive negotiations. The predecessor of Iridium under those contracts,
however, was a wholly owned subsidiary of Motorola at the time the Space System
Contract and Operations and Maintenance Contract were negotiated and therefore
these negotiations were not conducted on an arm's-length basis. Moreover,
although these agreements provide for specific prices, Motorola's obligations
and liabilities thereunder are subject to certain limitations which allocate
various risks to Iridium and may have the effect of increasing the price paid by
Iridium. Iridium's payment obligations under these agreements are expected to
comprise most of its expenses.
 
CONFLICTS OF INTEREST WITH GATEWAY OWNERS
 
     The Iridium Board consists of representatives of certain of the world's
leading telecommunications companies. Almost all of the members of the Iridium
Board have been appointed by investors in Iridium who also are gateway owners
and service providers. Because Iridium will be a supplier to the gateways and
the service providers, the interests of Iridium are expected to conflict in
certain respects with the interests of the gateway owners and the service
providers. For example, this conflict of interest will be relevant in setting
the wholesale prices that Iridium will charge for airtime and other Iridium
World Services.
 
YEAR 2000 CONSIDERATIONS
 
     In the next eighteen months, most companies using computer systems will be
confronted with the fact that many software application and operation programs
written in the past may not properly recognize calendar dates beginning in the
Year 2000. This issue could cause computers to shut down or provide incorrect
information. While Year 2000 considerations are not expected to materially
affect Iridium's internal operations, they may adversely affect Iridium's
suppliers, gateway operators, service providers and roaming partners. Iridium
has begun to ask its suppliers, gateway operators, service providers and roaming
partners about their progress in identifying and addressing problems that their
computer systems may face in correctly processing date information for the Year
2000. While Iridium expects that substantially all of its suppliers, gateway
operators, service providers and roaming partners will effectively address the
Year 2000 issue, there
<PAGE>   8
 
can be no assurance that the failure of such persons to address effectively the
issue will not have an adverse effect on Iridium's results of operations.
 
ALLEGED HEALTH RISKS
 
     Certain media reports have suggested possible links between the use of
portable cellular telephones which integrate transmitting antennas into their
handsets and certain health risks, including cancer, as well as possible
interference between digital cellular telephones and pacemakers, hearing aids
and other electronic medical devices. The FCC has issued amended and updated
guidelines for evaluating environmental radio frequency radiation from
FCC-regulated transmitters. These guidelines are intended to protect the public
from health risks due to exposure to radio frequency energy. Similar guidelines
were issued in 1996 by the International Commission on Non-Ionizing Radiation
Protection, an international body assigned to develop guidelines regarding
non-ionizing radiation. Guidelines are also being considered by certain other
international agencies. No assurance can be given that in the future other
standards bodies will not issue standards that could require or otherwise result
in phone modifications which may materially and adversely affect Iridium.
