               NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

1.       BASIS OF PRESENTATION

         In the opinion of management, the accompanying unaudited condensed
financial statements reflect all adjustments necessary for a fair presentation
of the financial position of Iridium World Communications Ltd. ("IWCL") as of
September 30, 1997 and its results of operations for the three and nine month
periods then ended, and its cash flows for the nine month period then ended.
These condensed financial statements are unaudited and do not include all
related footnote disclosures.  These financial statements should be read in
conjunction with the audited financial statement and footnotes thereto included
in the registration statement on Form S-1 (333-23419, 23419-01), dated June 9,
1997.

         Since its inception on December 12, 1996 through September 30, 1997,
IWCL has not entered into any operating transactions or incurred any expenses.
The results of operations for the three and nine months ended September 30,
1997 are not necessarily indicative of the results of operations expected in
the future.

         In March and June 1997, IWCL registered with the Securities and
Exchange Commission a total of 13,800,000 shares of its Class A Common Stock
("Class A Common Stock") for sale in an initial public offering (the
"Offering"), and on June 13, 1997 IWCL consummated the Offering and issued
12,000,000 shares.  Pursuant to the 1997 Subscription Agreement between IWCL
and Iridium LLC ("Iridium"),  approximately $225 million in net proceeds from
the Offering were invested in Iridium Class 1 Membership Interests, at which
time the outstanding shares of Class A Common Stock held by Iridium were
retired, and IWCL became a member of Iridium.

2.       NEW ACCOUNTING PRONOUNCEMENT

         In February 1997, the Financial Accounting Standards Board issued
Statement No. 128, "Earnings per Share"  ("Statement 128").  Statement 128
supersedes Accounting Principles Board Opinion No. 15, "Earnings per Share"
("APB 15") and its related interpretations, and promulgates new accounting
standards for the computation and manner of presentation of earnings (loss) per
share data.  IWCL is required to adopt the provisions of Statement 128 for the
year ending December 31, 1997.  Earlier application is not permitted; however,
upon adoption of Statement 128 IWCL will be required to restate previously
reported annual and interim earnings (loss) per share data in accordance with
the provisions of Statement 128.  IWCL does not believe that the adoption of
Statement 128 will have a material impact on the computation or manner of
presentation of its earnings (loss) per share data as presented under APB 15.

3.       STOCKHOLDERS' EQUITY

         On July 16,1997, Iridium and Iridium Capital Corporation, a wholly
owned subsidiary of Iridium, completed an offering (the "High Yield Offering")
of (i) 300,000 units, each consisting of $1,000 principal amount of 13% Senior
Notes due 2005, Series A ("Series A Notes"), and one IWCL Warrant, representing
the right to purchase 5.2 shares of Class A Common Stock of IWCL and (ii) $500
million aggregate principal amount of 14% Senior Notes due 2005, Series B
("Series B Notes").  The Series A Notes and Series B Notes are guaranteed by
Iridium Roaming LLC and Iridium IP LLC.  IWCL is not an obligor of the Series A
Notes or Series B Notes.  The IWCL Warrants represent, in aggregate, the right
to purchase 1,560,000 shares of Class A Common Stock of IWCL.  Approximately
$17,113,000 of the proceeds of the High Yield Offering was allocated to the
purchase price of the IWCL Warrants.  The exercise price of each IWCL Warrant
is $20.90 per share.  The IWCL Warrants are exercisable at anytime on or after
one year from the date of original issuance and expire on July 15, 2005.
Concurrent with the issuance of the IWCL Warrants in the High Yield Offering,
Iridium issued to IWCL 1,560,000 LLC Interest Warrants, each exerciseable for
one Class 1 Interest at an exercise price of $20.90 per LLC Interest Warrant.
The LLC Interest Warrants are designed to be exercised upon the exercise of the
IWCL Warrants.

         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS




1.       ORGANIZATION

         Iridium LLC ("Iridium") is devoting its present efforts to developing
and commercializing a global wireless telephony system - the IRIDIUM(R)
communications system (the "IRIDIUM System") - that will enable subscribers to
send and receive telephone calls virtually anywhere in the world - all with one
phone, one phone number and one customer bill.

2.       BASIS OF PRESENTATION

         In the opinion of management, the accompanying unaudited condensed
consolidated financial statements reflect all adjustments, consisting of only
normal recurring accruals, necessary for a fair presentation of the financial
position of Iridium and subsidiaries as of September 30, 1997, and the results
of their operations for the three and nine month periods ended September 30,
1997 and 1996, and the period from June 14, 1991 (inception) through September
30, 1997, and their cash flows for the nine month period ended September 30,
1997 and 1996, and the period from June 14, 1991 (inception) through September
30, 1997.  These condensed consolidated financial statements are unaudited, and
do not include all related footnote disclosures.  The results of operations for
the three and nine months ended September 30, 1997 are not necessarily
indicative of the results of operations expected in the future, although the
Company will continue to be a development stage limited liability company and
anticipates a net loss for the year. These financial statements should be read
in conjunction with Iridium's audited consolidated financial statements and
footnotes thereto included in the registration statement on Form S-1
(333-23419, 23419-01), dated June 9, 1997.

3.       ACCOUNTING FOR SATELLITES LOST AT LAUNCH OR FAILING IN ORBIT

         The costs of constructing and placing satellites into service are
capitalized.  Losses from satellite failures for which Iridium has financial
responsibility under its contractual arrangements with Motorola are recognized
currently.  Motorola bears the risk of loss for launch failures and satellite
failures before a satellite is placed into service.

4.       MEMBERS' EQUITY

         On April 16, 1997, the Limited Liability Company Agreement of Iridium
was amended to increase the authorized number of Class 1 Interests from
3,000,000 to 225,000,000.  On May 9, 1997, Iridium effected a 75 for 1
subdivision of its Class 1 Membership Interests whereby each existing Class 1
Interest was subdivided into 75 Class 1 Interests.   All interest and per
interest data appearing in the unaudited condensed consolidated financial
statements and notes thereto have been retroactively adjusted for the
subdivision.

         On May 9, 1997, Iridium entered into a definitive agreement with South
Pacific Iridium Holdings Limited ("SPI"), an affiliate of P.T. Bakrie
Communications Corporation ("Bakrie"), pursuant to which SPI acquired from
Iridium 7,500,000 Class 1 Interests at $13.33 per interest.  The transaction
closed on May 30, 1997 with 40% of the total purchase price paid on that date
and the remainder due on or before May 1998.  Through September 30, 1997,
Iridium has received an aggregate of $59.2 million from SPI in satisfaction of
the commitment.

         On June 13, 1997, Iridium World Communications Ltd. ("IWCL"), a
wholly-owned subsidiary of Iridium as of that date, consummated an initial
public offering (the "Offering") of 12,000,000 shares of its Class A Common
Stock which resulted in proceeds of approximately $225 million to IWCL
(expenses of the offering were paid by Iridium). Pursuant to the 1997
Subscription Agreement between Iridium and IWCL, such proceeds were used to
purchase 12,000,000 Class 1 Interests in Iridium.  Upon consummation of the
Offering, all of the outstanding shares of IWCL held by Iridium were retired,
and IWCL became a member of Iridium.

         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


         Iridium declared approximately $1,317,000 and $1,580,000 in-kind
dividends to holders of Series A Class 2 Membership Interests during the three
month periods ended September 30, 1997 and 1996, respectively, and $4,924,000
and $2,419,000 for the nine month periods ended September 30, 1997 and 1996,
respectively.

5.       SUPPLEMENTAL CASH FLOW INFORMATION

         During the nine months ended September 30, 1997 and 1996, $80,970,000
and $14,934,000, respectively, of interest expense was incurred and capitalized
to the system under construction.  Interest paid was $24,344,000 during the
nine months ended September 30, 1997, and no amounts were paid for interest
during the nine months ended September 30, 1996.

         There were no income taxes paid during the nine months ended September
30, 1997, and the amount paid for income taxes was $6,192,000 during the nine
months ended September 30, 1996.

6.       TRANSACTIONS WITH MEMBER

         TERRESTRIAL NETWORK DEVELOPMENT CONTRACT

         As a result of technological developments, changes in the desired
product mix and features of the IRIDIUM services, the addition of enhanced
system capabilities, and scheduling adjustments, Iridium entered into an
amendment to the Terrestrial Network Development Contract ("TNDC") with
Motorola, Inc. ("Motorola"), effective July 15, 1997.  Aggregate payments under
the TNDC, as so amended, are expected to be approximately $284 million.

         GUARANTEED BANK FACILITY

         In accordance with the Agreement Regarding Guarantee between Iridium
and Motorola, pursuant to which Motorola guaranteed Iridium's obligations under
the Guaranteed Bank Facility, an additional 56,416 warrants to purchase
4,231,200 Class 1 Interests were earned by Motorola during the nine months
ended September 30,1997.  Iridium recognized $48,631,000 as expense during the
nine months ended September 30, 1997 in connection with the warrants earned by
Motorola.

         On July 21, 1997, Iridium permanently reduced the commitment of the
bank lenders under the Guaranteed Bank Facility from $750 million to $655
million.  On October 22, 1997, the commitment of the bank lenders under the
Guaranteed Bank Facility was further permanently reduced from $655 million to
$450 million.  As a result of the reduction, the maximum number of warrants
Motorola may earn as compensation for their guarantee of that facility until
maturity in August 1998 is 110,085 warrants to purchase approximately 8,256,375
Class 1 Interests.

7.       LONG TERM DEBT

         On July 16, 1997, Iridium and Iridium Capital Corporation, a wholly
owned subsidiary of Iridium, completed an offering (the "High Yield Offering")
of (i) 300,000 units, each consisting of $1,000 principal amount of 13% Senior
Notes due 2005, Series A ("Series A Notes"), and one IWCL Warrant representing
the right to purchase 5.2 shares of Class A Common Stock of IWCL, and (ii) $500
million aggregate principal amount of 14% Senior Notes due 2005, Series B
("Series B Notes").  The Series A Notes and Series B Notes are guaranteed by
Iridium Roaming LLC and Iridium IP LLC.  The aggregate net proceeds received
were approximately $746 million.  Interest on the Series A Notes and Series B
Notes is payable in cash semi-annually on January 15th and July 15th of each
year, commencing on January 15, 1998.  The notes are redeemable at the

         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

option of Iridium, in whole or in part, at any time on or after July 15, 2002.
The Series A and Series B Notes mature on July 15, 2005.  The IWCL Warrants
represent, in aggregate, the right to purchase 1,560,000 shares of Class A
Common Stock of IWCL.  The exercise price of each IWCL Warrant is $20.90 per
share, exercisable at any time on or after one year from the date of original
issuance, and expires on July 15, 2005.  Concurrent with the issuance of the
IWCL Warrants in the High Yield Offering, Iridium issued to IWCL 1,560,000 LLC
Interest Warrants, each exerciseable for one Class 1 Interest at an exercise
price of $20.90 per LLC Interest Warrant.  The LLC Interest Warrants provide
that one LLC Interest Warrant must be exercised upon the exercise of each IWCL
Warrant.  Approximately $17,113,000 of the proceeds of the High Yield Offering
was allocated to the purchase price of the Iridium Interest Warrants.

         Iridium has received a commitment letter from Chase Securities Inc.,
The Chase Manhattan Bank, Barclays Bank PLC and BZW, the investment banking
division of Barclays Bank PLC, for a Secured Bank Facility in a principal
amount up to $750 million, to be secured by substantially all of Iridium's
assets and by the Reserve Capital Call, defined as the contractual commitment
by 17 of Iridium's investors to purchase up to 18,206,550 Class 1 Interests at
$13.33 per interest.  Borrowings under the Secured Bank Facility would mature
on September 30, 1998, subject to Iridium's right to extend such maturity until
June 30, 1999 if it can demonstrate by July 1, 1998 that it has sufficient
available or committed financing for its approved project costs through
such extended maturity.  The availability of the Secured Bank Facility is
subject to significant conditions, including the execution of satisfactory
definitive documentation, technical conditions relating to the IRIDIUM System,
conditions relating to regulatory approvals and conditions relating to other
financing sources.

8.       NEW ACCOUNTING PRONOUNCEMENT

         In February 1997, the Financial Accounting Standards Board issued
Statement No. 128, "Earnings per Share" ("Statement 128").  Statement 128
supersedes Accounting Principles Board Opinion No. 15, "Earnings per Share"
("APB 15") and its related interpretations, and promulgates new accounting
standards for the computation and manner of presentation of Iridium's loss per
Class 1 Interest data.  Iridium is required to adopt the provisions of
Statement 128 for the year ending December 31, 1997.  Earlier application is
not permitted; however, upon adoption of Statement 128, Iridium will be
required to restate previously reported annual and interim loss per Class 1
Interest data in accordance with the provisions of Statement 128.  Iridium does
not believe that the adoption of Statement 128 will have a material impact on
the computation or manner of presentation of its loss per Class 1 Interest data
as currently or previously presented under APB 15.

         In June 1997, the Financial Accounting Standards Board issued
Statement No. 130, "Reporting Comprehensive Income" ("Statement 130").
Statement 130 establishes standards for the reporting and display of
comprehensive income and its components in the financial statements.  Iridium
is required to adopt the provisions of Statement 130 for the year ending
December 31, 1998.  Earlier application is permitted; however, upon adoption of
Statement 130, Iridium will be required to reclassify previously reported
annual and interim financial statements.  The disclosure of comprehensive
income in accordance with the provisions of Statement 130 will impact the
manner of presentation of its financial statements as currently and previously
reported.

9.       SUBSEQUENT EVENT

         On October 17, 1997, Iridium and Iridium Capital Corporation, a wholly
owned subsidiary of Iridium, completed an offering of $300 million principal
amount of 11 1/4% Senior Notes due 2005, Series C ("Series C Notes").  The
Series C Notes are guaranteed by Iridium Roaming LLC and Iridium IP LLC.  The
net proceeds received were approximately $293 million.  Interest on the Series
C Notes is payable in cash semi-annually on January 15th and July 15th of each
year,

option of Iridium, in whole or in part, at any time on or after July 15, 2002.
The Series C Notes mature on July 15, 2005.

10.      IRIDIUM SUBSIDIARIES

         Iridium's Series A Notes, Series B Notes and Series C Notes are
co-issued by Iridium Capital Corporation ("Capital") and are fully and
unconditionally guaranteed, jointly and severally, on a senior unsecured basis
by Iridium Roaming LLC and Iridium IP LLC (together with Capital, the "Iridium
Subsidiaries").  Each of the Iridium Subsidiaries is a wholly-owned subsidiary
of Iridium and, as of September 30, 1997, Iridium has no subsidiaries other
than the Iridium Subsidiaries.  The following is summarized financial
information of the Iridium Subsidiaries as of September 30. 1997 and for the
period from inception of each Iridium Subsidiary through September 30, 1997.
Full financial statements of the Iridium Subsidiaries are not presented because
management believes they are not material to investors.

ITEM 2.

                       IRIDIUM WORLD COMMUNICATIONS LTD.
                                      AND
                                  IRIDIUM LLC
                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS



         IWCL is a member of Iridium and has no other business.  IWCL's sole
assets are its Class 1 Interests in Iridium and its LLC Interest Warrants, and
IWCL's results of operations reflect its proportionate share of the results of
operations of Iridium on an equity accounting basis.

         Iridium is currently devoting its entire efforts to establishing and
commercializing the IRIDIUM communications system (the "IRIDIUM System").  As
such, Iridium's current principal activities relate to managing the design,
construction and development of the system and preparing for its day-to-day
operations.  Each of Iridium Capital Corporation, Iridium Roaming LLC and
Iridium IP LLC is a wholly-owned subsidiary of Iridium.  See IWCL's and
Iridium's financial statements and notes thereto included elsewhere in this
quarterly report.

FORWARD LOOKING INFORMATION

         Iridium is a development stage enterprise.  Accordingly, many
statements in this report are forward looking.  Examples of such forward
looking statements include, but are not limited to, the statements concerning
Iridium's operations, funding needs, financial sources, schedule for
commencement of commercial operations, the estimate of the last year in which
Iridium will have negative cash flow and a net increase in year-end borrowings,
and future licensing and regulatory developments, as well as information
concerning expected characteristics of competing systems and expected actions
of third parties, including, but not limited to, systems contractors, equipment
suppliers, gateway operators, service providers and roaming partners.  These
forward looking statements are based on a number of assumptions and are
inherently predictive and speculative.  One or more of the assumptions
underlying such forward looking statements is likely to be incorrect.
Therefore, actual results may be materially different from those expressed or
implied by such statements.

         Factors which may cause IWCL's or Iridium's results to differ
materially from those expressed or implied by such forward looking statements
include, but are not limited to, (i) Iridium's absence of current revenues,
highly leveraged capital structure and significant additional funding needs,
(ii) delays and cost overruns related to the construction and deployment of the
IRIDIUM System, (iii) technological risks related to the development and
implementation of the various components of the IRIDIUM System, (iv) customer
acceptance of Iridium's services, (v) satellite launch, operation and
maintenance risks, (vi) risks associated with the need to obtain operating
licenses in the numerous countries where Iridium assumes it will provide its
services, (vii) competition from satellite and terrestrial communications
services and (viii) Iridium's dependence on Motorola, Inc. ("Motorola") and its
other members for the construction and operation of the IRIDIUM System and the
distribution and marketing of Iridium's services.  These factors, and other
factors that may materially affect Iridium's operations, are described in
greater detail in the Securities and Exchange Commission filings of IWCL and
Iridium, including Exhibit 99.1 to this report.

LIQUIDITY AND CAPITAL RESOURCES

         Funding Requirements

         Iridium will require substantial amounts of continued outside
financing to acquire and develop its assets and to commence operations.  With
respect to the IRIDIUM System, Iridium and Motorola have entered into (i) the
Space System Contract for the design, development,





                                       16
<PAGE>   17
production and delivery in orbit of the space segment, (ii) the Terrestrial
Network Development Contract to design the gateway hardware and software, and
(iii) the Operations and Maintenance Contract to provide day-to-day management
of the space segment after deployment and to monitor, upgrade and replace
hardware and software of the space segment as necessary to maintain performance
specifications. Substantially all of the initial capital raised by Iridium is
being used and will continue to be used to make payments to Motorola under the
Space System Contract and, to a lesser extent, the Terrestrial Network
Development Contract.  The Space System Contract provides for a fixed price of
$3.45 billion (subject to certain adjustments), scheduled to be paid by Iridium
to Motorola over approximately a five-year period for completion of milestones
under the contract.  Payments under the Operations and Maintenance Contract
will be payable quarterly and are expected to aggregate approximately $2.88
billion over such contract's initial five-year term (assuming commencement of
commercial operations on September 23, 1998 and no excusable delays), in
addition to the cost of certain spare satellites at the completion of the
contract.  The payments increase each year, ranging from quarterly payments of
$129.4 million in 1998 to $157.4 million in 2003 to $171.4 million in 2005.  If
Iridium exercises its option to extend the Operations and Maintenance Contract
for an additional two years, the payments due for that two-year extension are
expected to aggregate approximately $1.33 billion (assuming commencement of
commercial operations on September 23, 1998 and no excusable delays).  The
Terrestrial Network Development Contract provides for payments aggregating
approximately $284 million through 1999.  As a result of technological
developments, changes in the product mix of the IRIDIUM Service, and scheduling
adjustments, including the implementation of ICRS (Iridium Cellular Roaming
Service) into Iridium's service offerings, there have been, and Iridium
anticipates there will be, amendments and interpretations of the Space System
Contact, the Terrestrial Network Development Contract and the Operations and
Maintenance Contract and other agreements and letters with Motorola which may
increase the total costs of these contracts.

         Through September 30, 1997, Iridium incurred expenditures totaling
$2.84 billion to Motorola under the Space System Contract in respect of
completed milestones and expenditures totaling $106 million under the
Terrestrial Network Development Contract.  Based on current estimates and the
current planned schedule, Iridium's expected future cash requirements by year
under the contracts through December 31, 1999 are approximately as follows:

         Iridium will also require funds for working capital, business software
development, interest on anticipated borrowings, financing costs and operating
expenses until some time after the commencement of commercial operations.
Iridium's interest expense will increase significantly as a result of its
financing plan.  During commercialization, Iridium will be required to make
payments to Motorola under the Operations and Maintenance Contract.  After
December 31, 1999 (the last year in which Iridium projects negative cash flow
and a net increase in year-end outstanding borrowings), Iridium expects that
its obligations relating to the Operations and Maintenance Contract and funds
needed for working capital, capital expenditures and debt service should be
funded through operations.  Iridium anticipates cash funding requirements of
approximately $4.4 billion through September 1998, the month Iridium expects to
commence commercial operations, and $5.3 billion (net of assumed revenues
following commencement of commercial operations) through year-end 1999, the
last year in which Iridium projects negative cash flow and a net increase in
year-end borrowing.

         The foregoing information reflects Iridium's current estimate of its
funding requirements through year-end 1999.  Actual amounts may be expected to
vary from such estimates for a





                                       17

variety of reasons, including unforeseen construction, integration or
regulatory delays or launch failures.  See "- Forward Looking Information."

         Sources of Funding

         As of September 30, 1997, Iridium had equity investments of $1.982
billion, including approximately  $224 million in net proceeds from the IWCL
initial public offering and $42 million due from South Pacific Iridium Holdings
Limited pursuant to the terms of a definitive purchase agreement.  At September
30, 1997, debt equaled approximately $1.016 billion, including a $655 million
Guaranteed Bank Facility, under which $235 million was outstanding as of
September 30, 1997.  On October 22, 1997, Iridium permanently reduced the bank
commitments under the Guaranteed Bank Facility to $450 million.  Borrowings
under the Guaranteed Bank Facility are guaranteed by Motorola (the "Motorola
Guarantee").

         On July 16, 1997, Iridium and Iridium Capital Corporation, a wholly
owned subsidiary of Iridium, completed an offering (the "Initial High Yield
Offering") of (i) 300,000 units, each unit consisting of $1,000 principal
amount of 13% Senior Notes due 2005, Series A (the "Series A Notes"), and one
IWCL Warrant, representing the right to purchase 5.2 shares of Class A Common
Stock of IWCL and (ii) $500 million aggregate principal amount of 14% Senior
Notes due 2005, Series B (the "Series B Notes"), for aggregate net proceeds of
approximately $746 million.  On October 17, 1997, Iridium and Iridium Capital
Corporation completed an offering (the "Second High Yield Offering") of $300
million aggregate principal amount of 11 1/4% Senior Notes due 2005, Series C
(the "Series C Notes") for aggregate net proceeds of approximately $293
million.  The Series A, Series B and Series C Notes mature on July 15, 2005 and
are guaranteed by Iridium IP LLC and Iridium Roaming LLC.

         Pursuant to the Memorandum of Understanding, dated July 11, 1997,
between Iridium and Motorola (the "Motorola MOU"), in addition to Motorola's
guarantee of indebtedness under the Guaranteed Bank Facility (reduced to $450
million on October 22, 1997).  Motorola has conditionally agreed to guarantee
up to $350 million of additional indebtedness (including principal and
interest) under the Guaranteed Bank Facility or another credit facility on
identical terms (the "Motorola Additional Guarantee"), provided that borrowings
under such additional indebtedness are made on or prior to February 28, 1999.
Borrowings under the Guaranteed Bank Facility mature in August 1998.   Pursuant
to the Motorola MOU, Motorola has agreed to extend the Motorola Guarantee
(including the Motorola Additional Guarantee, if committed) until after July
15, 2005, if the Guaranteed Bank Facility is so extended.  Iridium believes it
would be able to amend the Guaranteed Bank Facility to increase its amount to
the extent of the Motorola Additional Guarantee and to extend its maturity
until after July 15, 2005, if it so requests.  There can be no assurance,
however,  that the bank lenders will agree to increase the amount of the
Guaranteed Bank Facility or to extend the term of the Guaranteed Bank Facility,
if so requested by Iridium, or that any such other identical credit facility
would be available.

         Iridium has received a commitment letter from Chase Securities, Inc.,
The Chase Manhattan Bank, Barclays Bank PLC and BZW, the investment banking
division of Barclays Bank PLC, for a bank facility (the "Secured Bank
Facility") in a principal amount up to $750 million, to be secured by
substantially all of Iridium's assets and by the Reserve Capital Call (as
defined).  The availability of the Secured Bank Facility is subject to
significant conditions, including execution of satisfactory definitive
documentation, technical conditions relating to the IRIDIUM System, conditions
relating to regulatory approvals and distribution agreements and conditions
relating to other financing sources.  Borrowings under the Secured Bank
Facility would mature on September 30, 1998, subject to Iridium's right to
extend such maturity until June 30, 1999 if it can demonstrate by July 1, 1998
that is has sufficient available or committed financing for its approved project
costs through such extended maturity.  After giving effect to the $745 million
received from the Series A and Series B Notes on July 16, 1997, the $293 million
received from the Series C Notes on October 17, and assuming approximately $450
million of borrowings under the Guaranteed Bank Facility (extended through
Iridium's commencement of commercial operations as discussed above) and full
utilization of the Secured Bank Facility, Iridium expects to have sufficient
cash to meet its anticipated funding





                                       18
<PAGE>   19
requirements through September 1998, the month Iridium expects to commence
commercial operations.  Iridium is seeking 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.

         Additional financing may also need to be obtained through the issuance
of equity or debt securities in the public or private markets.  The
availability and terms of any such financing are uncertain and are dependent,
in part, on market conditions existing at the time of any proposed financing.
Iridium's estimated funding requirements will increase, perhaps substantially,
in the event of unexpected cost increases or schedule delays.  Additional
equity financing, if pursued, may be raised either privately from strategic or
financial investors, or through additional public offerings. Pursuant to the
Motorola MOU, Iridium agreed that, to the extent the net proceeds to Iridium of
senior note offerings prior to December 31, 1997 including the Series A and
Series B Notes), exceed $650 million, it will apply such excess to a permanent
reduction of the commitments of the lenders under the Guaranteed Bank Facility
(provided that such commitments need not be reduced to an amount less than $275
million). On July 21, 1997 such commitments were reduced to $655 million as a
result of the Initial High Yield Offering.  In connection with the issuance of
the Series C Notes, Motorola waived this requirement with respect to proceeds
in excess of $205 million.  As a result, on October 22, 1997, Iridium reduced
the commitments under the Guarantee Bank Facility from $655 million to $450
million.

         In connection with the Secured Bank Facility, the bank lenders will
require a security interest in substantially all of Iridium's assets and the
Reserve Capital Call, defined as the contractual commitment by 17 of Iridium's
investors to purchase up to 18,206,550 Class 1 Interests at $13.33 per
interest.  The bank lenders also will require that the membership interests in
Iridium, or any company to which all or substantially all of Iridium's assets
are transferred, be pledged as security under the Secured Bank Facility.  In
connection with granting such security interest, Iridium expects to enter into
a transaction whereby Iridium will establish a new wholly-owned subsidiary and
transfer all or substantially all of its assets and liabilities to that
subsidiary with Iridium remaining as a holding company for the new entity.
Iridium would then pledge all of the membership interests in the new entity to
the bank lenders in connection with the Secured Bank Facility.  The new entity
is expected to be a member-managed limited liability company with Iridium
acting as the sole member and would assume Iridium's obligations with respect
to currently outstanding indebtedness of Iridium.

         As a result of Iridium's outstanding debt and the expected incurrence
of significant additional indebtedness required to meet its capital
requirements, Iridium will have substantial indebtedness.  The debt instruments
governing indebtedness contain restrictions on, among other things, the
incurrence of indebtedness and the payment of cash dividends.  Iridium's
ability to meet all of its debt service obligations when due will require it to
generate significant cash flow from operations or, if necessary, make
additional borrowings to refinance its outstanding indebtedness.  No assurance
can be made that Iridium will be able to generate sufficient cash flow to meet
its debt service obligations or that it will be able to refinance indebtedness.



OPERATIONS

         Iridium is a development stage company and, as such, will not generate
any revenues from operations until the IRIDIUM System is constructed and
deployed, and commercial operations commence, which is currently anticipated to
be in September 1998.  To date, Iridium's only source of income has been
interest income on the cash and investment balances from the proceeds of equity
commitments, which amounted to approximately $13.8 million from July 29, 1993
(the "Initial Capital Contribution Date") to September 30, 1997.  During the
same period, Iridium recorded a net loss of $287 million.  In addition, during
the years ended December 31, 1991 and 1992, and the period from January 1, 1993
to the Initial Capital Contribution Date, aggregate costs of $14.8 million were
incurred by Motorola.  Such costs were paid by Iridium to Motorola pursuant to
a reimbursement agreement.





                                       19
<PAGE>   20
         As a development stage company, Iridium has incurred losses since its
inception and will continue to do so for the forseeable future.  Iridium's
ability to become profitable and generate positive cash flow is dependent on
the successful and timely commencement of the operation of the IRIDIUM System,
wide subscriber acceptance and numerous other factors.

        Capitalization of Costs

         All payments by Iridium under the Space System Contract are being
capitalized.  These capitalized costs are then depreciated over the five-year
estimated life of the satellites.  Depreciation expense is realized on a
satellite-by-satellite basis, commencing with the delivery of each satellite to
its mission orbit.  Depreciation related to the ground control stations
commences with the placement in service of each such station.  The costs of
constructing and placing satellites into service are capitalized.  Losses from
satellite failures for which Iridium has financial responsibility under its
contractual arrangements with Motorola are recognized currently.  Motorola
bears the risk of loss for launch failures and satellite failures before a
satellite is placed into service.  Iridium has obtained a satellite insurance
policy to cover certain costs associated with the loss of a satellite.
Capitalized amounts under the Space System Contract and the Terrestrial Network
Development Contract aggregated $2.95 billion through September 30, 1997.  In
addition, costs incurred in connection with the issuance by Iridium of Class 1
Interests are reflected as a reduction of additional paid-in capital and debt
issuance costs are deferred and amortized over the term of the related
indebtedness.  Payment of these costs and charges has resulted in significant
negative operating cash flow.  Certain interest expenses have and will also be
capitalized.

         A portion of the payments made under the Operations and Maintenance
Contract will be capitalized and depreciated.  Any costs under the Operations
and Maintenance Contract not capitalized will be expensed.

        Operating Expenses

         For the period from the Initial Capital Contribution Date through
September 30, 1997, marketing, general and administrative expenses were
approximately $293 million.  During the period prior to the Initial Capital
Contribution Date, total accumulated expenditures of approximately $14.8
million were incurred, primarily to reimburse Motorola for expenses associated
with operating Iridium during the period from its incorporation in 1991 through
the Initial Capital Contribution Date.  Iridium expects a substantial increase
in future operating expenditures relating to sales, marketing and other costs
associated with commercialization.

        Interest Expense

         Iridium expects to finance a significant portion of its capital
requirements through borrowings.  As a result of these borrowings, Iridium will
have significant interest costs.  Interest costs are being capitalized while
the system is under construction.  This has resulted in all interest costs
being capitalized during 1995, 1996, and the three and nine month periods ended
September 30,1997, and will likely result in similar capitalization for the
remainder of 1997, with the expectation that a meaningful portion of interest
cost will be expensed in 1998 and all interest cost will be expensed beginning
in 1999.  Some portion of interest expense will not be paid in cash, including
the interest expense related to Iridium's 14 1/2 % Senior Subordinated Notes
through March 1, 2001.  Such non-cash interest is accrued and such accrual
increases outstanding indebtedness on Iridium's balance sheet.

        Income Taxes

         Iridium reports its income as a partnership for United States federal
income tax purposes and accordingly, is not expected to be directly subject to
U. S. federal income tax.  Iridium may, however, be subject to tax in some
state, local or foreign jurisdictions on portions of its income.
