                   NOTES TO THE UNAUDITED FINANCIAL STATEMENTS

1.     ORGANIZATION AND BUSINESS

Iridium World Communications Ltd. ("IWCL", the "Debtor" or the "Company") was
incorporated under the laws of Bermuda on December 12, 1996. At inception, IWCL
was wholly owned by Iridium LLC ("ILLC"), a Delaware limited liability company.
In June 1997, IWCL consummated an initial public offering and issued 12,000,000
shares of Class A Common Stock. Pursuant to the 1997 Subscription Agreement
between IWCL and ILLC, approximately $225 million in net proceeds from the
Offering were invested in 12,000,000 Class 1 Membership Interests of ILLC (Class
1 Interests), at which time the outstanding shares of Class A Common Stock held
by ILLC were retired, and IWCL became a member of ILLC.

On January 21, 1999, IWCL issued 7,500,000 shares of Class A Common Stock in a
public offering resulting in net proceeds of $242,400,000. Pursuant to the Share
Issuance Agreement between IWCL and ILLC, such proceeds were used by IWCL to
purchase 7,500,000 Class 1 Interests in ILLC.

ILLC through its wholly-owned subsidiary Iridium Operating LLC ("IOLLC"), a
Delaware limited liability company, has completed its efforts to develop and
deploy a global wireless personal communications system. IOLLC commenced
commercial satellite phone service on November 1, 1998 and commercial satellite
paging service on November 15, 1998. ILLC's transition from a development stage
limited liability company to an operating limited liability company has been
adversely affected by various factors, including much slower than expected
subscriber growth. As a result of these factors, on August 13, 1999, bankruptcy
petitions were filed with respect to ILLC and certain of their affiliates. See
Note 3 for a description of the bankruptcy proceedings.

IWCL's sole asset is its investment in ILLC. As of November 30, 1999, IWCL owned
19,753,238 Class 1 Interests, representing approximately 13.25% of the total
outstanding Class 1 Interests in ILLC.

2.     BASIS OF PRESENTATION

These unaudited financial statements have been prepared for the purpose of
filing with the United States Bankruptcy Court for the Southern District of New
York. These unaudited financial statements have not been prepared in accordance
with generally accepted accounting principles ("GAAP") because Statement of
Financial Accounting Standards No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of" ("SFAS 121") has
not been applied by ILLC, and certain other disclosures required under GAAP have
been omitted.

SFAS 121 requires a company to evaluate the recoverability of its long-lived
assets whenever events or circumstances indicate that the carrying amount of
such assets may be impaired. If considered impaired, SFAS 121 requires that the
long-lived assets be written down to fair value. ILLC's long-lived assets are
comprised of the Iridium Space System and related assets. The Company expects
that, upon application of SFAS 121, the carrying amount of ILLC's long-lived
assets will be written down by a material amount; however, at this time it is
not possible to determine such amount. The accompanying unaudited financial
statements also omit certain disclosures required under GAAP, including earnings
(loss) per share data.

With the exceptions described above, in the opinion of management, all other
accounting principles applicable to the Company have been applied in the
accompanying unaudited financial statements and all adjustments necessary for a
fair presentation of such information have been


   6

made. However, there could also be year-end audit adjustments and adjustments to
certain other accounts as a result of the Company's filing for protection under
Chapter 11 of the United States Bankruptcy Code.

In connection with the bankruptcy proceedings the Company has adopted AICPA
Statement of Position 90-7, "Financial Reporting by Entities in Reorganization
Under the Bankruptcy Code" ("SOP 90-7"). SOP 90-7 requires entities in
bankruptcy to present their pre-petition liabilities on the basis of the
expected amount of allowed claims in accordance with Statement of Financial
Accounting Standards No. 5, "Accounting for Contingencies".

3.     BANKRUPTCY FILING

On August 13, 1999 (the "Petition Date"), certain creditors of IOLLC and its
subsidiary, Iridium Capital Corporation filed involuntary bankruptcy petitions
against them in the United States Bankruptcy Court for the Southern District of
New York (the "Court"). Also, on August 13, 1999, the ILLC, IOLLC, Iridium
Capital Corporation and IWCL filed voluntary petitions in the United States
Bankruptcy Court for the District of Delaware. On August 16, 1999, the Court
entered an order, which, among other things, stayed the Delaware petitions. On
September 13, 1999 (the "Conversion Date"), the Court entered an order granting
the ILLC, IOLLC, IWCL and Iridium Capital Corporation relief under Chapter 11 of
Title 11 of the US Bankruptcy Code (the "Bankruptcy Code"). Additionally, on the
Conversion Date, three additional IOLLC subsidiaries, Iridium IP LLC, Iridium
(Potomac) LLC and Iridium Roaming LLC and on December 16, 1999 Iridium
Promotions, Inc. (together and collectively with the other companies the
"Debtors") filed voluntary petitions for relief under Chapter 11 of the
Bankruptcy Code.

In Chapter 11 bankruptcy proceedings, certain claims in existence prior to the
order of relief, including pending litigation against the Company are stayed
while the Company continues it's business operations as a debtor-in-possession.
These accrued claims are reflected in the balance sheets as "Liabilities Subject
to Compromise". Additional liabilities subject to compromise may arise
subsequent to the filing date resulting from rejection of executory contracts,
including leases, and from the determination by the Court (or agreed to by
parties in interest) of allowed claims for contingencies and other disputed
amounts. Prior to the Conversion Date, the Debtors continued to pay expenses and
claims, including pre-petition claims. The Debtors received approval from the
Bankruptcy Court, effective September 13, 1999, to pay certain of its
pre-petition and pre-conversion obligations, including employee wages and
related taxes and gap period claims (those claims incurred between the Debtors'
Petition Date and the Conversion Date).

From the Conversion Date until December 15, 1999, ILLC's operations were funded
pursuant to cash collateral orders agreed to by the lenders and approved by the
Court. On December 15, 1999, the Court approved an extension of the use of cash
collateral through February 15, 2000, provided, however, that all cash subject
to the bank lien be used only to pay interest to the lenders and certain other
limited expenses. To fund ongoing operations and restructuring costs, current
investors, led by Motorola, agreed to provide ILLC $20 million to continue its
operations through February 15, 2000.

In addition to the interim funding of ILLC, Motorola has continued to operate
and maintain the satellite constellation without any cash payment for this
service. Motorola will be under no obligation to provide this service after
February 15, 2000 unless it is paid for the service on a current basis in cash.

IWCL and ILLC operate under a Management Services Agreement, whereby, ILLC
manages the day-to-day operations of IWCL, including, but not limited to, the
treasury and accounting functions. ILLC receives no fees or reimbursement from
IWCL for these services.

4.     INVESTMENT IN IRIDIUM LLC

IWCL's sole asset is its investment in Iridium LLC. For the period from November
1 through November 30, 1999, IWCL's equity in losses of ILLC were approximately
$15.1 million. Because IWCL has recognized losses to date that equal IWCL's
investment in ILLC and since IWCL has no commitment to fund losses of ILLC
beyond its investment, losses of ILLC otherwise attributable to IWCL have not
been recognized to the extent such losses exceed IWCL's investment in ILLC.

Substantially all liabilities of ILLC and its subsidiaries are subject to
compromise or other treatment under a plan of reorganization that must be
confirmed by the Court after a vote of ILLC and subsidiaries' impaired
claimants. The ultimate effect of the Chapter 11 bankruptcy proceedings on each
of the various claimants will depend on a variety of factors, including, without
limitation, the specific terms of a confirmed plan of reorganization and the
relative rank of each claim among the priorities established by the Bankruptcy
Code. In addition, there can be no assurance that ILLC and its subsidiaries will
successfully reorganize under the Chapter 11 proceeding. Accordingly, the
ultimate effect of ILLC's bankruptcy proceeding on IWCL, is not currently
determinable.
