                      COMSAT CORPORATION AND SUBSIDIARIES
        Notes to Condensed Consolidated Financial Statements (Unaudited)

1.   Financial Statement Presentation

     The accompanying unaudited condensed consolidated financial statements have
     been prepared by COMSAT Corporation pursuant to the rules and regulations
     of the SEC. These financial statements should be read together with the
     financial statements and notes in our 1998 Annual Report on Form 10-K filed
     with the SEC. Certain information and footnote disclosures normally
     included in financial statements prepared in accordance with generally
     accepted accounting principles have been condensed or omitted. The
     accompanying condensed consolidated financial statements reflect all
     adjustments and disclosures which, in our opinion, are necessary for a fair
     presentation. All such adjustments are of a normal recurring nature. The
     results of operations for the interim periods are not necessarily
     indicative of the results of the entire year.

2.   Agreement and Plan of Merger with Lockheed Martin Corporation

     COMSAT and Lockheed Martin Corporation entered into an Agreement and Plan
     of Merger on September 18, 1998. Under the terms of the merger agreement,
     Lockheed Martin will acquire all of the outstanding common stock of COMSAT
     in a two-step transaction. We incurred merger costs of $2.1 million in the
     second quarter of 1999 and $3.9 million in the first six months of 1999 in
     connection with the proposed merger. See "Management's Discussion and
     Analysis of Financial Condition and Results of Operations - Outlook" on
     page 16 of this Form 10-Q and Note 2 to the financial statements in our
     1998 Form 10-K for additional information regarding the merger.

3.   Inmarsat Privatization

     Inmarsat completed its privatization on April 15, 1999. As a result,
     we now use the equity method of accounting to report our 22.2% ownership in
     the new company. Prior to 1999, we consolidated our share of the accounts
     of Inmarsat and reported our share of Inmarsat's revenues (net of space
     segment costs paid to Inmarsat), cost of services, depreciation and
     amortization and interest costs in the respective categories of our income
     statement. We now report our proportionate share of Inmarsat's net
     operating results as equity income in the "Other income (expense), net"
     category of our income statement. Space segment charges paid to Inmarsat
     are now reported in cost of services. Equity income from our investment in
     Inmarsat was $3.2 million for the three months and $9.0 million for the six
     months ended June 30, 1999.

     As a result of the privatization and consistent with the equity method of
     accounting, we reclassified Inmarsat related amounts from property and
     equipment, current maturities of long-term debt, due to related parties and
     long-term debt to form our investment in Inmarsat.


                                       5

<PAGE>

     During March 1999, Inmarsat made a special cash distribution to the
     signatories. We recorded our share of the distribution of $31.2 million as
     a reduction of our investment in Inmarsat.

4.   INTELSAT Share Change

     During 1999, we paid $38.1 million to increase our total ownership share of
     INTELSAT from 18.4% at December 31, 1998 to 20.4%.

5.   Regulatory Environment and Litigation

     Regulatory Environment. Under the Communications Satellite Act of 1962, the
     International Maritime Satellite Telecommunications Act of 1978 and the
     Communications Act of 1934, COMSAT is subject to regulation by the Federal
     Communications Commission with respect to its capital and organizational
     structure, and with respect to its World Systems and Mobile Communications
     businesses. FCC decisions and policies have had and will continue to have a
     significant impact on COMSAT. In addition, the telecommunications companies
     which we operate in various developing countries are subject to regulation
     by the local regulatory bodies in those countries. Because the regulatory
     environment in those countries is rapidly evolving as the local economies
     are developing, these companies face increasing business uncertainties that
     could have an adverse effect on their operations.

     On October 28, 1998, the FCC issued a notice of proposed rulemaking that
     looks toward enabling users to have direct access to the INTELSAT system,
     which would end our status as the exclusive provider of INTELSAT services
     in the U.S. Legislation also has been passed by the Senate to amend the
     Satellite Act. We discuss these regulatory and legislative developments
     under "Management's Discussion and Analysis of Financial Condition and
     Results of Operations - Outlook" on page 19 of this Form 10-Q.

     Litigation. COMSAT and its subsidiaries are parties to various lawsuits and
     arbitration proceedings, and are subject to various claims and inquiries,
     which generally are incidental to the ordinary course of our business. See
     Note 8 for a description of an arbitration proceeding related to the Green
     Bank contract to which we are a party. The outcome of legal proceedings
     cannot be predicted with certainty. Based on currently available
     information, however, we do not believe that the outcome of any matter
     which is pending or threatened, either individually or in the aggregate,
     will have a material adverse effect on our long-term consolidated financial
     condition. Nevertheless, the outcome of such matters could materially
     affect our consolidated results of operations in a given year or quarter.

     In January 1999, the U.S. Department of Justice announced that it intended
     to join a lawsuit filed by former employees of Electromechanical Systems,
     Inc. under the qui tam provisions of the Civil False Claims Act. We
     acquired Electromechanical Systems in 1994 as part of our acquisition of
     Radiation Systems, Inc., which became part of


                                       6
<PAGE>

     COMSAT RSI, Inc. We began accounting for COMSAT RSI as a discontinued
     operation in 1997 and retained Electromechanical Systems when we sold
     COMSAT RSI in 1998 (see Note 8). The lawsuit names Electromechanical
     Systems, COMSAT, COMSAT RSI, and several current and former
     Electromechanical Systems employees and seeks potential damages estimated
     at up to $40.0 million. The Department of Justice is expected to seek to
     stay the lawsuit pending the outcome of a separate criminal investigation
     into the same allegations that is currently being conducted by the U.S.
     Attorney's office in Tampa, Florida. We intend to vigorously defend this
     matter but cannot predict the ultimate outcome or estimate the amount of
     liability that could result from any civil or criminal sanctions the
     government may seek.

7.   Comprehensive Income

     Comprehensive income consists of net income and other gains and losses
     affecting our stockholders' equity that, under generally accepted
     accounting principles, are excluded from net income. For COMSAT, such items
     consist primarily of foreign currency translation gains and losses and
     unrealized gains and losses on marketable equity securities. The components
     of total comprehensive income (loss) are presented in the following table:

</TABLE>
     The foreign currency translation loss resulted from the devaluation of the
     Brazilian currency (the Real) this year. The unrealized loss on securities
     includes $8.2 million, net of tax, for the three months ended June 30, 1999
     and $12.4 million, net of tax, for the six months ended June 30, 1999 to
     reflect COMSAT's investment in ICO Global Communications (Holdings) Limited
     at market value. See "Management's Discussion and Analysis of
     Financial Condition and Results of Operations - Outlook - ICO Global
     Communications" on page 21 of this Form 10-Q. The unrealized loss on
     securities also includes reclassification adjustments of $8.5 million, net
     of tax, for the three months ended June 30, 1999 and $16.7 million, net of
     tax, for the six months ended June 30, 1999, related to the sale of stock
     in Viatel, Inc.

8.   Discontinued Operations

     On June 25, 1998, we sold substantially all of COMSAT RSI, Inc. In
     connection with the sale, COMSAT and the purchaser agreed to indemnify each
     other against certain losses. Our indemnification obligations generally are
     limited to losses incurred in excess of an agreed threshold amount ($6.7
     million) and are capped at a maximum agreed amount ($28.0 million) in
     respect of claims made within an agreed survival period (generally,
     approximately two years). In certain instances, however, our
     indemnification obligations are not subject to those limitations.

     Certain of COMSAT RSI's assets were excluded from the sale and retained by
     COMSAT, including Electromechanical Systems, Inc. and a long-term
     construction contract for a radio astronomy telescope in Green Bank, West
     Virginia. We also retained a claim against the prime contractor to recover
     $29.0 million in costs incurred in performing the Green Bank contract,
     which are in excess of the original contract value. The prime contractor
     has filed a counterclaim seeking $12.9 million in damages for delay. The
     claim and


                                       8
<PAGE>


     counterclaim are currently in arbitration. We may not be successful in
     collecting all or any portion of this claim.

     The loss upon disposition of discontinued operations is based upon our best
     estimates of the costs to complete the Green Bank contract, the amount to
     be realized from the $29.0 million Green Bank contract arbitration claim,
     potential indemnification claims and other costs related to the
     discontinued operations. These estimates could change as additional costs
     are incurred to complete the Green Bank contract, upon resolution of the
     arbitration and upon resolution of other matters related to the COMSAT RSI
     discontinued operations.

     The net assets of COMSAT RSI remaining were $21.2 million at June 30, 1999
     and $15.0 million at December 31, 1998. The net assets consist primarily of
     receivables on long-term contracts, fixed assets, current liabilities and
     the remaining reserve for the estimated loss on disposal.

9.   New Accounting Pronouncements

     In June 1998, the Financial Accounting Standards Board issued Statement of
     Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative
     Instruments and Hedging Activities.  "The statement requires companies to
     recognize all derivatives as either assets or liabilities, with the
     instruments measured at fair value. The accounting for changes in fair
     value and gains or losses depends on the intended use of the derivative and
     its resulting designation. The statement was originally effective for
     fiscal years beginning after June 15, 1999. In June 1999, the Financial
     Accounting Standards Board issued SFAS No. 137, "Accounting for Derivative
     Instruments and Hedging Activities - Deferral of the Effective Date of FASB
     Statement No. 133 an amendment of FASB Statement No. 133." SFAS No. 137
     delays the effective date of SFAS No. 133 by one year, to June 15, 2000. We
     will adopt SFAS No. 133 in the first quarter of 2001. We are evaluating the
     impact that implementation of SFAS No. 133 will have on our consolidated
     financial statements.

     We evaluate the performance of our operating segments based on income
     (loss) before income taxes and interest costs. The "Other" column includes
     the elimination of intersegment revenues, corporate related items, and
     interest costs, net of amounts capitalized. We continue to report our
     proportionate share of Inmarsat's net operating results in the Mobile
     Communications' segment.

     Mobile Communications' total assets declined from $454.7 million at
     December 31, 1998 to $327.5 million at June 30, 1999, primarily as a result
     of the Inmarsat privatization (see note 3).

Item 2: Management's Discussion and Analysis of Financial Condition and Results
        of Operations for the Quarter Ended June 30, 1999

                             ANALYSIS OF OPERATIONS

Consolidated Operations

     Mobile Communications, one of our four operating segments, now uses the
equity method to account for our 22.2% investment in Inmarsat. Prior to 1999, we
used the pro rata method of consolidation to report our share of Inmarsat's
operating results. While the change in accounting method did not affect our
consolidated net income, it did affect certain categories on the income
statement. We now report our proportionate share of Inmarsat's net operating
results as equity income in the "Other income (expense), net" category of the
income statement.

Revenues

     Consolidated revenues in the second quarter of 1999 were $155.9 million, an
increase of 3% when compared to the same period of 1998. For the six months
ended June 30, 1999, revenues of $300.4 million were 2% higher than the
comparative period of last year. Revenues improved in World Systems,
International and Laboratories. Lower revenues in Mobile Communications
partially offset the improvement in our other segments.

Operating Income

     Operating income for the second quarter was $18.0 million, which was $2.9
million below the same period of last year. For the year-to-date period,
operating income was $30.8 million, or $9.8 million below the comparative period
of 1998. The change in the method of accounting for our investment in Inmarsat,
lower Mobile Communications revenues and costs related to the proposed merger
with Lockheed Martin Corporation predominately caused the decreases. Improved
operating income in World Systems partially offset those items.

Other Income (Expense), Net

     Other income was $14.0 million for the second quarter of 1999, as compared
to expense of $1.0 million for the second quarter of 1998. The improvement in
other income is the result of a $12.6 million pre-tax gain from Internationals
sale of stock in Viatel, Inc. and $3.2 million of equity income from Mobile
Communications investment in Inmarsat. For the six months ended June 30, 1999,
other income was $31.1 million, which compares to an expense of $3.8 million for
the same period in 1998. The year-to-date improvement includes $25.7 million in
pre-tax gains from the sale of Viatel stock and $9.0 million in equity income
from Mobile Communications investment in Inmarsat. Year-to-date 1998 results
included a $2.0 million non-cash write-off of the Laboratories investment in
Superconducting Core Technologies, Inc. in the first quarter of 1998.




                                    12

<PAGE>

Interest Costs, Net of Amounts Capitalized

     Interest costs, net of amounts capitalized for the second quarter of 1999,
were $9.6 million, or $3.1 million lower than the second quarter of last year.
For the first half of this year, interest costs, net of amounts capitalized were
$19.4 million, or $4.7 million below the comparative period of 1998. Lower
levels of borrowings and the reclassification of Mobile Communications' share of
Inmarsat interest costs as a component of "Other income (expense), net"
generated the improvement.

Income before Income Taxes

     Income before income taxes for the second quarter was $22.4 million, an
improvement of $15.2 million over the same period of 1998. For the year-to-date
period, income before income taxes was $42.5 million, which was $29.8 million
better than the first six months of 1998. The improvement in both periods was
primarily the result of the gain from the sale of Viatel stock and higher
earnings from World Systems. Lower Mobile Communications revenues and costs
associated with the proposed merger with Lockheed Martin partially offset those
items.

Income Tax Expense

     For the second quarter of 1999, income tax expense was $10.4 million, or
$7.3 million higher than the second quarter of 1998. Income tax expense for the
first six months of this year was $18.5 million, which was $13.7 million more
than the same period last year. Improved earnings and a higher effective tax
rate than the comparative periods of 1998 led to the increases.

Net Income

     Net income for the second quarter of 1999 was $12.0 million, an improvement
of $7.9 million over the same period of 1998. For the six months ending June 30,
1999, net income was $24.0 million, which was $16.1 million better than the
comparative period of last year. Earnings per share on a fully-diluted basis for
the second quarter were $0.22, or $0.14 higher than the same period of 1998. For
the first half of 1999, earnings per share on a fully-diluted basis were $0.45,
which was an increase of $0.30 as compared to the same period in 1998.

Segment Operating Results

     We report our operating results in four segments: World Systems, Mobile
Communications, International and Laboratories. We evaluate the performance of
our operating segments based on segment income (loss) before taxes and interest
costs.

     In our 1998 Form 10-Q reports, we presented our operating results in two
segments: Satellite Services and Network Services. The Satellite Services
segment included World Systems and Mobile Communications. The Network Services
segment included International, Laboratories and Government Programs. We began
reporting International and Laboratories as

separate segments in the fourth quarter of 1998. We now include the results of
Government Programs as part of the World Systems segment.

World Systems

     Revenues in World Systems in the second quarter of this year were $86.3
million, an increase of 13% over the same period in 1998. For the first half of
1999, World Systems revenues were $165.2 million, which was an improvement of
11% as compared to the same period of last year. The improvement in revenues was
primarily the result of increased demand for Internet services and other
high-speed data traffic and our increased ownership in INTELSAT. In 1999, we
paid $38.1 million to increase our total ownership share of INTELSAT from 18.4%
to 20.4%. A slight decline in voice revenues partially offset these increases.

     Segment income in World Systems in the second quarter was $32.0 million, an
increase of 23% as compared to second quarter of 1998. For the first six months
of 1999, World Systems segment income was $61.3 million, or 18% higher than the
first half of last year. Revenue growth, lower operating expenses and increased
ownership in INTELSAT contributed to the improvement in segment income.

Mobile Communications

     Inmarsat completed its privatization on April 15, 1999. As a result, we now
use the equity method of accounting to report our 22.2% ownership in the new
company. Prior to 1999, we used the pro rata method of consolidation to report
our share of Inmarsat's operating results. Under the pro rata method of
consolidation, we reported our share of Inmarsat's revenues (net of the space
segment charges that we paid to Inmarsat), cost of services, depreciation and
amortization and interest costs in the appropriate categories of our income
statement. We now report our proportionate share of Inmarsat's net operating
results as equity income in "Other income (expense), net" within the Mobile
Communications operating segment. The space segment charges that we pay to
Inmarsat are now reported in cost of services. Our share of Inmarsat's interest
costs and income taxes are now reported within the Mobile Communications
segment. Prior to 1999, our share of Inmarsat's interest costs were reported in
"Interest costs, net of amounts capitalized" and taxes related to our income
from Inmarsat were reported in "Income tax expense."

     Revenues in Mobile Communications for the second quarter were $30.9
million, or 23% below the second quarter of 1998. Mobile Communications revenues
in the first half of 1999 were $60.6 million, or 25% below the same period last
year. Lower analog telephone traffic, principally due to lower usage in the U.S.
Government sector, and lower amounts of carrier traffic primarily caused the
declines. In addition, reporting Inmarsat's revenues using the equity method of
accounting lowered Mobile Communications' revenues by $4.5 million in the second
quarter and $6.1 million in the first six months of 1999.

     Mobile Communications' segment income in the second quarter of 1999 was
$4.1 million, as compared to $7.4 million in the second quarter of 1998. For the
six months ended June 30, 1999, Mobile Communications segment income was $8.9
million, versus $16.3 million in the same period of last year. The decline in
Mobile Communications segment income was due to lower revenues, and reporting
our share of Inmarsat's interest costs and income taxes within the Mobile
Communications segment. Mobile Communications' results include interest costs
and income taxes of $2.2 million for the second quarter and $3.2 million for the
first half of 1999. The year-to-date 1998 results also included a non-recurring
$1.0 million gain on the sale of an investment.

International

     International's second quarter 1999 revenues were $27.7 million, or 2%
higher than the second quarter of 1998. For the six months ended June 30, 1999
Internationals revenues were $55.4 million, or 6% better than the same period
of last year. Revenues in International's company in Brazil decreased compared
to last year due to the devaluation of the Brazilian currency. Improvements in
Argentina, Mexico and Colombia offset lower revenues in Brazil.

     Segment income for International in the second quarter was $9.5 million,
compared to a loss of $3.8 million for the same period of 1998. International's
segment income for the first six months of 1999 was $18.3 million, which
compares to a segment loss of $8.2 million in the first




                                    15

<PAGE>

half of 1998. During the second quarter of 1999, we sold our remaining
investment in Viatel and recognized a gain of $12.6 million. For the six months
ended June 30, 1999, our total gain on the sale of Viatel stock was $25.7
million. Excluding the gains on the sale of Viatel stock, International had
segment losses of $3.1 million in the second quarter of 1999 and $7.4 million in
the first half of 1999. Economic conditions in Latin America constrained growth
in International's companies operating in Argentina, Brazil and Venezuela.

Laboratories

     The Laboratories' revenues in the second quarter of 1999 were $13.3
million, or 16% higher than the second quarter of last year. For the six months
ended June 30, 1999, Laboratories' revenues were $23.2 million, or 13% better
than last year. The improvement in revenues was due to growth in our technical
consulting and product businesses. The segment loss in the second quarter was
$200,000, which compares to segment income of $100,000 in the second quarter of
1998. For the year-to-date period, the segment loss was $1.7 million, which was
$700,000 better than the $2.4 million loss recorded in the first half of 1998.
The prior year results included a $2.0 million non-cash write-off of our
investment in Superconducting Core Technologies, Inc. Absent this write-off, the
Laboratories' segment loss in the first half of 1999 was $1.3 million higher
than the same period of 1998 and was primarily due to increased research and
development costs.

     Many of the statements that follow are forward looking and relate to
anticipated future events and operating results. Statements that look forward in
time are based on management's current expectations and assumptions, which may
be affected by subsequent developments and business conditions, and necessarily
involve risks and uncertainties. These statements and the corporation's future
operating results may be affected by the timing and outcome of regulatory and
other governmental proceedings, legislative actions, developments concerning the
privatization of INTELSAT, the proposed acquisition of COMSAT by Lockheed Martin
Corporation, international and domestic business conditions, increased
competition from other satellite services providers, the disposition of assets
and completion of contracts placed in discontinued operations, the effect of the
year 2000 issue on COMSAT, litigation and other factors. Therefore, there can be
no assurance that actual future results will not differ materially from
anticipated results. Although we have attempted to identify some of the
important factors that may cause actual results to differ materially from those
anticipated, those factors should not be viewed as the only factors that may
affect future operating results.

Business Combination with Lockheed Martin

     COMSAT entered into an Agreement and Plan of Merger with Lockheed Martin
Corporation on September 18, 1998. Under that agreement, Lockheed Martin agreed
to acquire all of COMSAT's outstanding common stock in a two-step transaction.

     The first step is a tender offer, which was commenced on September 25,
1998, by a subsidiary of Lockheed Martin, Regulus LLC, to purchase up to 49% of
COMSAT's outstanding


                                       16

<PAGE>

common stock at a price of $45.50 per share. The tender offer is currently
scheduled to expire on August 31, 1999 but will be extended, as necessary, until
September 18, 1999.

     The tender offer will be completed only if the conditions set forth in the
merger agreement are satisfied. Some of those conditions are:

     o at least one-third of COMSAT's outstanding common stock must be tendered
       in the offer;

    o  COMSAT shareholders must approve the merger;

    o  receipt of all required consents and approvals from government
       authorities, including FCC approval for Lockheed Martin to become an
       authorized carrier and acquire up to 49% of COMSAT's common stock in the
       tender offer and expiration of all waiting periods under antitrust laws;
       and

    o  there is no event that has had or would reasonably be expected to have a
       material adverse effect on COMSAT.

     The second step is a proposed merger pursuant to which COMSAT will merge
with a wholly-owned subsidiary of Lockheed Martin. In the merger, shareholders
will receive one share of Lockheed Martin common stock for each share of COMSAT
common stock that they own.

     The merger will be completed only if the conditions set forth in the merger
agreement are satisfied. Some of those conditions are:

     o completion of the tender offer;

     o amendment of the Communications Satellite Act of 1962 to permit
       completion of the merger;

     o receipt of all consents and approvals from governmental authorities; and

     o there is no event that has had or would reasonably be expected to have a
       significant adverse effect on COMSAT.

     We are working toward completing the tender offer and merger. However, we
do not yet know when or whether the tender offer or merger will be completed as
the conditions to each step are beyond our control.

     COMSAT and Lockheed Martin have estimated that the regulatory approvals
necessary to complete the tender offer could be obtained in time to permit the
tender offer to close before September 18, 1999. In January 1999, Representative
Tom Bliley, Chairman of the House Committee on Commerce, and Senator Conrad
Burns, Chairman of the Senate Commerce Subcommittee on Communications, sent a
letter to William E. Kennard, Chairman of the FCC, urging the FCC not to take
any action to permit Lockheed Martin to purchase more than



                                       17
<PAGE>
10 percent of COMSAT prior to Congress adopting new satellite legislation. If
the FCC does not proceed with its review of Lockheed Martin's filings related to
the tender offer, or if the FCC delays or slows its review or if it awaits
Congressional action on legislation, the tender offer will not be completed by
September 18, 1999. Moreover, the tender offer cannot be completed without
requisite antitrust clearances, which have not been attained. The requisite FCC
approvals and antitrust clearance may not be obtained before September 18, 1999.

     If Congress does not adopt amendments to the Satellite Act in the next few
months, the merger will not occur in 1999, even if the tender offer is
completed. If, however, Congress adopts amendments to the Satellite Act in the
1999 or 2000 legislative session, the merger may occur afterwards, depending
upon when the FCC grants approvals necessary to complete the merger. No
assurance can be given that the requisite legislation will be enacted. If
legislation enabling the merger is enacted, FCC approval of the merger will be
required in addition to the approvals required for the tender offer. While it is
expected that the FCC would act promptly on the matter following enabling
legislation, the FCC's response time could affect the estimated time frame for
closing the merger.

     If the tender offer is not completed by September 18, 1999 or if the merger
is not completed by September 18, 2000, either Lockheed Martin or COMSAT may
terminate the merger agreement. Lockheed Martin or COMSAT may elect not to do
this or together may elect to amend the merger agreement so that the tender
offer or merger could be completed after those dates.

Restructuring of Inmarsat and INTELSAT

     The privatization of Inmarsat was completed on April 15, 1999. We now own
22.2% of Inmarsat Holdings, Ltd., a new, independent commercial company based in
London, England. The new company is not currently publicly traded but is
expected to conduct an initial public offering within approximately two years of
the privatization, subject to market conditions. As a result of the
privatization, we are using the equity method to account for our investment in
Inmarsat. We previously used the pro rata consolidation method. This reporting
change is not expected to have a material effect on our net income.

     In November 1998, INTELSAT transferred six satellites (five currently in
orbit and one expected to be launched during the 1999-2000 time frame) to New
Skies Satellites N.V. New Skies, which is headquartered in the Netherlands, is
an entirely separate, independent company spun off from INTELSAT. We use the
cost method to account for our 16.6% direct ownership of New Skies. Prior to its
creation, the assets and operating results relating to New Skies were included
as part of the INTELSAT system and were accounted for using the pro rata
consolidation method. During 1998, our share of pre-tax earnings related to the
satellites transferred to New Skies was approximately $3 million. As a result of
this change in accounting, World Systems' 1999 pre-tax earnings will be lower by
approximately this amount in the absence of other factors that may affect
operating results.



                                       18
<PAGE>


     INTELSAT's management and Board of Governors are continuing efforts to
transform INTELSAT from a treaty-based, intergovernmental organization to a
fully-private, commercial company. At its June 1999 meeting, the INTELSAT Board
of Governors decided to focus its restructuring efforts by developing a business
plan which assumes that the new INTELSAT will be operated as some form of
corporation. Based on the timetable approved at INTELSAT's April Meeting of
Signatories, it appears that INTELSAT may be in a position to complete its
restructuring prior to the end of 2001, the time frame we had previously
established as our objective for privatizing INTELSAT. While the new privatized
company initially will not be publically traded, it is expected that a initial
public offering may be achievable in 2002, subject to market conditions and the
actual date of incorporation of the restructured INTELSAT. We are committed to
privatizing INTELSAT in a pro-competitive manner at the earliest possible time.
As a minority shareholder and the U.S. Signatory to INTELSAT, however, we lack
the ability to independently effect a restructuring of INTELSAT. The success of
our efforts will depend on our ability to achieve a consensus among other
Signatories and participating member governments. A two-thirds vote of the
governments that are members of INTELSAT will be necessary for approval of any
final privatization proposal.

Legislative and Regulatory Developments

     On July 1, 1999, the U.S. Senate passed the Open-market Reorganization for
the Betterment of International Telecommunications (ORBIT) Act (S. 376) by
unanimous consent. Senator Conrad Burns, Chairman of the Senate Commerce
Subcommittee on Communications, introduced the ORBIT legislation. COMSAT
believes that the ORBIT legislation, on the whole, represents a constructive
approach to the privatization of INTELSAT and deregulation of COMSAT.
Significantly, the ORBIT legislation would repeal the ownership restrictions on
COMSAT stock upon enactment and eliminate other outdated provisions in the
Satellite Act. We do have concerns with some provisions of the bill, including a
requirement that the President withdraw the U.S. from this international
organization if the full privatization is not achieved by 2002. Although we
believe privatization of INTELSAT will be completed rapidly, United States
withdrawal from INTELSAT in 2002, if privatization is not completed, would have
a substantial adverse effect on our financial condition and results of
operations. Amendments to the ORBIT legislation addressed direct access and
standards to govern FCC licensing of Inmarsat and New Skies as privatized
companies and INTELSAT after that organization is privatized.

     The House of Representatives is expected to consider satellite legislation
this year, most likely in the form of legislation being prepared by
Representative Tom Bliley, Chairman of the House Committee on Commerce. At this
time, Representative Bliley's timetable for introducing satellite legislation is
unclear. Last year, the House passed a bill introduced by Representative Bliley
entitled the Communications Satellite Competition and Privatization Act of 1998
(H.R. 1872). We opposed H.R. 1872 because it contained provisions that, in our
view, would have adversely affected our results of operations and the value of
our shareholders' investments in the INTELSAT and Inmarsat satellite systems.
The Clinton Administration opposed H.R. 1872 in testimony before the Senate
Commerce Committee late last year and in hearings on S. 376 in March of this
year.



                                       19

     On October 28, 1998, the FCC issued a notice of proposed rulemaking that
looks toward enabling users to have direct access to the INTELSAT system, which
would end COMSAT's status as the exclusive provider of INTELSAT services in the
United States. In the direct access notice, the FCC tentatively concluded, among
other things, that it lacks the statutory authority to impose Level 4 direct
access (by which users could invest and acquire an ownership interest in
INTELSAT) but does have the authority to require Level 3 direct access (by which
users could contract directly with INTELSAT for capacity and bypass COMSAT). The
FCC sought comments on its tentative conclusion that it would serve the public
interest to mandate Level 3 direct access. Some of COMSAT's largest customers
and other users filed comments supporting direct access, and also urged the FCC
to void COMSAT's long-term carrier contracts under the so-called "fresh look"
doctrine. COMSAT filed comments contesting the basis for the FCC's proposal to
implement Level 3 direct access and opposed the fresh look requests. Depending
on form and timing, the imposition of direct access could have an adverse effect
on our financial condition and results of operations. However, we do not believe
that the FCC has authority under the Satellite Act to eliminate COMSAT's
exclusive franchise access and would contest the exercise of such authority by
the FCC as only Congress can modify the statutory scheme that applies to COMSAT.
There is no assurance that our judicial challenge to direct access would
succeed.

     In October 1998, Congress passed, and the President subsequently signed,
the International Anti-Bribery Act of 1998. The Act provides that, as of May 1,
1999, an international organization providing commercial satellite services will
not be accorded immunity from suit or legal process in connection with its
provision of such service, except as required by international agreements to
which the United States is a party that are so designated by the President. The
Act requires the President to designate those agreements which are subject to
the exception and directs the President to take all appropriate actions to
reduce or eliminate all privileges and immunities that are not preserved by
designation. COMSAT opposed prior versions of this legislation but supported it
in the form ultimately passed by Congress. We do not believe that enactment of
this legislation will have a material effect on our business, because Inmarsat
was privatized before May 1, 1999, and the Department of State, acting under
delegated authority, has now designated the INTELSAT Headquarters Agreement as
an international agreement to which the United States is a party, thereby
requiring the United States to continue to afford INTELSAT immunity from suit
and legal process under the Act.

     In June 1998, the FCC issued a public notice requiring U.S. earth stations
using INTELSAT satellites that were scheduled to be transferred to New Skies to
file license modification applications in order to access the New Skies system.
Several companies, including COMSAT, filed applications in response to this
notice. On August 6, 1999, the FCC granted these applications for a three-year
license term, finding that New Skies' entry into the U.S. market would not pose
a very high risk to competition, but that New Skies was not yet fully
independent of INTELSAT. U.S. earth stations may now access New Skies satellites
for both domestic and international services. The Commission stated that it
would consider extending these licenses for a full ten-year term upon an
appropriate showing by New Skies. In the meantime, it directed New Skies to file
quarterly status reports on its plans for an initial public offering and other
steps toward independence.

1999 Earnings Outlook

     We expect earnings performance in the second half of 1999 to continue at
approximately the same level as in the first half of 1999, excluding the
one-time gains on our sale of Viatel, Inc. stock and costs associated with the
proposed merger with Lockheed Martin.

     The instability of the Brazilian Real, as well as the current economic
climate within Brazil, are expected to negatively impact growth and financial
performance of International's operations in Brazil during 1999. The Brazilian
Real has declined approximately 45% in value as compared to the U.S. Dollar
between January 1, 1999 and June 30, 1999, and is no longer tied to a fixed
trading range. In 1998, COMSAT Brazil was International's largest operating
company, accounting for approximately 40% of International's revenues. In
addition, we are beginning to see the effects of economic downturns in other
Latin American countries such as Argentina and Venezuela.

ICO Global Communications

     COMSAT has a 1.6% direct ownership interest in ICO Global Communications
(Holdings) Limited. ICO is a development stage company, which was formed to
provide hand-held satellite communications services. In addition to our direct
investment in ICO, we have an indirect investment in ICO through our equity
ownership in Inmarsat, which also is an ICO shareholder. To date, ICO has raised
approximately $3 billion in financing. ICO has stated that it needs
approximately $1.6 billion in additional funding in order to complete the
development of its system and fund its operations through deployment. ICO also
has stated that it will require substantial additional funding until it begins
to generate positive cash flow from operations. ICO continues to seek the funds
that will enable it to complete the system. ICO's ability to raise additional
capital will be dependent upon market conditions and other factors which are
potentially beyond its control. There can be no assurance that ICO will be
successful in its efforts to raise additional capital. If ICO is unable to raise
sufficient capital to complete the system, the value of our investment in ICO
could be impaired or lost.

     At June 30, 1999, the market value of our direct investment in ICO was
$16.2 million. Our cost basis for this investment was $36.0 million. During the
first half of 1999, we recognized an unrealized loss of $12.4 million, net of
taxes, in comprehensive income (loss) to account for a decline in the current
market value of this investment. Under generally accepted accounting principles,
unrealized gains (losses) on marketable securities are reported as a component
of comprehensive income in stockholders' equity, but are excluded from net
income. If the reduction in the market value of our investment in ICO is
determined to be other than temporary, we will need to account for the reduction
in ICO's market value as a charge to net income at that time. In addition, since
we account for our ownership interest in Inmarsat using the equity method of
accounting, we also would recognize a portion of any realized loss that Inmarsat
would record related to its investment in ICO. Our cost basis for that indirect
investment was $34.7 million.

Year 2000 Issue (Year 2000 Readiness Disclosure)

     The year 2000 issue stems from existing computer programs that were written
using two digits rather than four digits to define the applicable year (e.g.,
"99" for 1999). Some computer programs that have date-sensitive software may not
operate properly when the last two digits become "00," as will occur on January
1, 2000. To the extent that this situation exists, there is the potential for
system failure or miscalculations, which could cause a disruption of operations.
The problem is not limited to computer programs, as some computer and other
operational equipment that have date-sensitive processors may not be able to
process dates after December 31, 1999.

     In the second half of 1996, we initiated a program to identify and address
year 2000 issues in order to avoid interruption to our operations at the turn of
the century. Each of our operating segments, as well as our administrative
functions, has completed the inventory and assessment phases of the year 2000
implementation plan and has completed remediation and testing of a majority of
the critical non-compliant systems identified during these two phases. We
presently believe that necessary changes to the remainder of our key computer
and other operational systems and equipment will be completed and tested by the
end of the third quarter of 1999.

     Our current estimate is that it will cost approximately $8 million prior to
January 1, 2000 to modify in-house management information systems, customer
products and other systems and equipment affected by the year 2000 issue. Of
this amount, we have spent approximately $6. million, or 75% of the projected
amount, through June 30, 1999. Year 2000 modifications and replacements are
based on management's current expectations and assumptions, which were derived
using assumptions of future events, including the continued availability of
resources and the reliability of third-party modification plans. Future events
that might cause material differences in management's current expectations and
assumptions include, but are not limited to, the availability and cost of
personnel with appropriate skills, the ability to locate and correct all
relevant computer code, reliance on third parties and similar uncertainties.

     While we are devoting substantial resources to our own year 2000 compliance
effort, COMSAT, as well as other international telecommunications carriers, will
be dependent, in part, on foreign and other third-party telecommunications
carriers being year 2000 compliant. The financial impact on World Systems and
Mobile Communications of foreign or third-party telecommunications carriers
failing to meet the year 2000 challenge would be realized in either of two ways:
loss of revenue due to the inability to complete the up-link or down-link
transmissions to or from a satellite and/or a decrease in our share of INTELSAT
and Inmarsat operating results. In recognition of the potential financial
exposure resulting from this dependency on foreign and third-party
telecommunications carriers, we have undertaken, as part of our year 2000
efforts, an analysis of the year 2000 compliance efforts of these
telecommunications carriers. In addition to this analysis, we are also utilizing
the results of efforts undertaken by the International Telecommunication Union
(ITU).

     World Systems derives in excess of 90% of its revenues under long-term
contracts. Almost all of these revenues are dependent upon termination with a
foreign telecommunication



                                       22
<PAGE>

carrier. Even though these long-term contracts are not subject to termination as
a result of the year 2000 issue, a significant portion of the expected future
World Systems revenues and our share of INTELSAT revenues is generated from
services between the United States and areas of the world that may be subject to
service interruptions resulting from year 2000 readiness issues. In addition,
Mobile Communications derives a significant portion of its revenues from
services either originating or terminating outside of the United States. If the
originating or terminating carrier is unable to initiate or terminate a call,
Mobile Communications, directly and indirectly through our share of Inmarsat
revenues, would be adversely affected by reduced revenues. It is not possible
for us to accurately quantify the amount, if any, of these exposures.

     International relies on third-party telecommunications carriers to provide
services to their customers. We have sought, but have not yet received, final
certification regarding year 2000 compliance from all of our third-party
carriers. We are developing appropriate contingency plans to mitigate, to the
extent possible, the effects of possible non-compliance by third-party carriers.


                        LIQUIDITY AND CAPITAL RESOURCES

     The primary source of cash during the first six months of 1999 was cash
from operations and the sale of Viatel stock. Our working capital at June 30,
1999 was $55.8 million, a decrease of $2.4 million from December 31, 1998. The
decline in working capital was due to a $38 million increase in current assets
primarily from the proceeds from sale of stock in Viatel, offset by higher
current liabilities of $40.4 million. The increase in current liabilities was
primarily from reclassifying the current portion of our share of INTELSAT's
long-term debt and certain other noncurrent liabilities to current liabilities.

     We have access to short-term and long-term financing at favorable rates.
Our current long-term debt ratings are A- from Standard and Poor's and A3 from
Moody's. Our current commercial paper ratings are A2 from Standard and Poor's
and P2 from Moody's. Following announcement of the proposed merger with Lockheed
Martin, both Standard and Poor's and Moody's placed their ratings on our
long-term debt under review for possible downgrades. The downgrades would take
effect as a result of merging the corporation with a lower-rated parent company.
The ratings for commercial paper are not under review at this time. The current
ratings on the Monthly Income Preferred Securities issued by COMSAT Capital I,
L.P. are BBB from Standard and Poor's and A3 from Moody's.

     Our $200 million commercial paper program had no borrowings outstanding at
June 30, 1999. A $200 million credit agreement, expiring at the end of 1999,
backs up our commercial paper program. We have an option to extend this credit
agreement by one-year to December 31, 2000. We had $36 million remaining under a
$100 million medium-term note program at June 30, 1999. The medium-term note
program is part of a $200 million debt securities shelf registration program
initiated in 1994.

     Our capital structure and debt-financing activities are regulated by the
FCC. Under the currently approved FCC guidelines, we are subject to a limit of
$200 million in short-term debt, a maximum long-term debt to total capital ratio
of 45% and an interest coverage ratio of 2.3 to 1.



                                       23

<PAGE>

The latter two guidelines are measured at year end. We were in compliance with
these guidelines as of June 30, 1999. If we were to fail to satisfy one or more
of the FCC guidelines, we would be required to seek advance FCC approval of
future financing activities on a case-by-case basis.



                                       24

Item 3.   Quantitative and Qualitative Disclosures About Market Risk

     We do not hold or issue derivative financial instruments. We finance our
operations and manage our interest rates through a combination of short-term
commercial paper, fixed-rate long-term debt and Monthly Income Preferred
Securities (MIPS) issued by a subsidiary. The MIPS pay a fixed dividend.
Borrowings under our short-term commercial paper program can expose our
operating results to changes in short-term rates. At June 30, 1999, no
commercial paper was outstanding.

     The corporation invests its excess cash in highly liquid investments with a
maturity of three months or less. Such investments can expose our operating
results to changes in short-term rates.

     International conducts its operations primarily through majority-owned and
wholly-owned subsidiaries. We have financed International's subsidiaries through
capital contributions. International's largest subsidiaries utilize the local
currency as their functional currency. Therefore, fluctuations in exchange rates
relative to the U.S. Dollar are recorded as cumulative translation adjustments
as a component of our stockholders' equity. Fluctuations in exchange rates
relative to the U.S. Dollar have not had a material impact on our cash flows or
results of operations.

the LESO's LES(s) and, as necessary, for any arrangement made pursuant to a
Shared LES Agreement duly authorised for operation through the LESO's LES(s).
The LESO shall have the right to maintain any LES lDs allocated to it by the
Organization that are in effect as of the Effective Date. The allocation and
maintenance of LES lDs shall be in accordance with the criteria in Annex C. Such
LES shall include any replacement antenna or switching facility.

consent to provide such additional Services in accordance with the terms and
conditions of this Agreement.

2.4 The LESO may enter into arrangements with any Reseller to provide Services
through the LESO's Land Earth Stations, subject to the following terms and
conditions:

(a)     ISPs.  The LESO shall provide written notice to the
        Company of the identity of any entity with which the LESO
        enters into an ISP arrangement no less than five (5) days
        prior to the commencement of the provision of Services by
        such entity as an ISP.  Following such notice, the Company
        shall allocate an ISP code to any such entity within five
        (5) days, provided that the LESO and such entity meet the
        Requirements specified in the ISP Mandatory Procedural
        Requirements set forth in Annex D hereof.  The Company may
        publish the name of any ISP or the relationship of any ISP
        with the LESO unless the LESO instructs the Company in
        writing not to publish such information; provided,
        however, that the Company may in all cases disclose such
        information in connection with fraud prevention activities.

(b)     Shared LES Agreements.  The LESO shall provide written
        notice to the Company of the identity of any entity with
        which the LESO enters into a Shared LES Agreement no less
        than five (5) days prior to commencement of LES
        authorisation testing preceding the provision of service
        under the Shared LES Agreement.  The host entity shall
        apply to the Company to utilize an LES ID and


                                       7

        to build an LES with the same system definition and to begin to provide
        service via such LES no later than six (6) months following the date on
        which the Company allocates the Shared LES ID, failing which the Company
        shall withdraw such Shared LES ID immediately following the expiration
        of such six-month period. The Company shall attribute traffic to the
        tenant entity in the Shared LES Agreement for traffic aggregation
        purposes in accordance with the agreement of the host and tenant
        entities, or if no such agreement exists, to the LESO as host entity.

(c)     Other Reseller Arrangements. The LESO shall have the right to enter into
        ---------------------------
        any arrangement for the distribution of Services through the LESO's Land
        Earth Station(s) with any type of Reseller other than an ISP or tenant
        in a Shared LES Agreement, or to engage any other agent or
        representative for that purpose, without further notice to or consent of
        the Company.

(d)     Responsibility for Compliance with Agreement. The LESO shall be
        --------------------------------------------
        responsible hereunder for the actions of any Resellers engaged by the
        LESO and shall assure the compliance of any such Reseller with the
        applicable terms and conditions of this Agreement, including without
        limitation, the LES Technical Criteria and Operating Procedures.

2.5  The Company shall consider any application by the LESO for the provision of
New Services via the Space Segment on such terms and conditions as may be
mutually agreed by the Parties, but the Company shall be under no obligation to
grant such authorisations.

2.6  In connection with its provision of Services via the Space Segment, the
LESO:

(a)     shall use reasonable efforts to promote the use of the
        Services that the LESO chooses to provide;

2.7

(a)     The Company has the right to authorise other entities, on a
        non-exclusive basis, to construct a Land Earth Station in order to
        provide Services via the Space Segment, provided that no such entity may
        be an Affiliate of the Company and the Company may not have any direct
        or indirect ownership interest in such entity. Such authorisations shall
        be on terms and conditions which are no more favourable to the newly
        authorised entity than those provided to the LESO under this Agreement.
        The Company shall notify the LES Operators of any new authorisation and
        the terms and conditions upon which such authorisation is granted within
        thirty (30) days of any such authorisation along with a certification
        that the terms provided to the newly authorised entity are not more
        favourabie than those provided to the LESO herein. Any entity authorized
        by the Company to construct a Land Earth Station to provide Services via
        the Space Segment following the Effective Date shall be considered an
        "LES Operator" for the purposes of this Agreement after the date on
        which each entity constructs the LES and enters with an agreement with
        the Company on such terms and conditions.

(b)     The Parties acknowledge that any former Signatory of the Organization
        that does not, at the Effective Date, own and operate an LES but which
        has notified the Company by the Effective Date of such former
        Signatory's intention to construct an LES and has satisfied the
        conditions set forth in Annex P, shall be authorised by the Company to
        provide Services via the Space Segment upon constructing a Land Earth
        Station and executing an agreement with the Company on the same terms
        and conditions as set forth herein, including the same expiration date
        for the Initial Term as all other LES Operators.

Establishment of LESs by the Company

2.8  During the Initial Term, the Company shall not be entitled to establish an
LES or to acquire an existing LES or to become the Affiliate of (or have any
other direct or indirect ownership interest in) an entity that operates an LES.

2.9  After the Initial Term, the Company shall be entitled to establish or
acquire (directly or through an Affiliate) LESs without limitation subject to
the following conditions:

(a)     In establishing or acquiring (directly or through an Affiliate) an LES,
        the Company shall be obligated to operate such LES through a
        structurally separate subsidiary (the "Subsidiary");




                                       9

<PAGE>

(b)     The Company shall apply no more favourable terms to such Subsidiary than
        it does to any other LES Operator; and

(c)     The Company shall procure that any relevant information, in any form
        whatsoever, including verbal information that is conveyed by it, its
        directors, officers, employees or agents to its Subsidiary, or the
        Subsidiary's directors, officers, employees or agents shall be
        contemporaneously made available to the LESO and all other LES
        Operators. For the purposes of this Clause, "relevant information" means
        any information which relates to LES operations and the provision of
        Services.

2.10 Throughout the Initial Term, neither the Company nor any Affiliate of the
Company may act as a Reseller of Services, or otherwise provide Services
directly to any entity that is not an LES Operator. In the event that the
Company or any Affiliate is permitted to act as a Reseller at any time during
the Extended Term, it shall do so only through a structurally separate
Subsidiary that complies with the provisions in Clause 2.9 above. Any Shared
Base Station ("SBS") will be used by the Company only for the purpose of routing
traffic to the LESO and other LES Operators to enable the LESO and other LES
Operators to provide IPDS or other relevant Services to their respective
Resellers and end-users and the Company shall not permit the interconnection of
the SBS with any entity that is not an LES Operator.

Restriction or withdrawal of a Service

2.11 The Company has the right to restrict or withdraw a Service in one or more
Ocean Regions subject to the following conditions:

(a)     The Company shall provide no less than one (1) year's written notice to
        the LESO and all LES Operators providing the Service to be restricted or
        withdrawn in the relevant Ocean Region(s) and specify the reasons for
        the restriction or withdrawal of the Service in question.

(b)     No later than thirty (30) days following the notice from the Company
        specified in paragraph (a) above, at the request of any LES Operator,
        the Company shall convene an LES User Group Meeting for the following
        purposes: (i) for the Company to consider the views of the LES Operators
        before implementing any proposed restriction or withdrawal; (ii) for the
        Company to demonstrate that the restriction or withdrawal satisfies the
        conditions in paragraph (c) below; and (iii) to define incentives to be
        offered to affected LESOs to facilitate orderly migration of end-users
        from a restricted or withdrawn service to another service, where
        possible, and a proposed transition schedule.




                                       10

<PAGE>


(c)     The following conditions shall apply to any proposed restriction or
        withdrawal of service:

        (i)  any restriction or withdrawal shall apply equally to all LES
             Operators which may have previously provided the Service within the
             relevant Ocean Region(s);

        (ii) The LESO shall be excused from any obligation to satisfy
             outstanding service and/or traffic commitments with respect to a
             withdrawn or restricted Service; and

  (iii) In determining whether to restrict or withdraw a Service, the Company
        shall take into account investments in equipment or facilities and
        contractual arrangements made by the LESO, other affected LES Operators
        and end-users in reliance upon the availability of the Service to be
        restricted or withdrawn and the possibility of continuing the Service in
        certain cases under mutually agreeable Lease arrangements.

(d)     The Company may restrict or withdraw a Service, unless
        doing so would conflict with its obligations under the
        Public Services Agreement between the Company and the
        Organisation ("Public Services Agreement") provided that a
        determination as to such a conflict shall be made solely
        by the parties to the Public Services Agreement in their
        absolute discretion. In the event that, following the
        Company's notification of its election to restrict or
        withdraw a Service in an ocean region, the Company becomes
        obligated by the Organization to maintain such Service to
        comply with the Public Services Agreement, and one or more
        LESOs wish to provide the Service in the ocean region, the
        Company shall be entitled to adjust the Charges for such
        Service but only in the ocean region in question, so as to
        enable it to recover all of its costs for providing the
        Service, plus a commercially reasonable rate of return
        (not to exceed 15 percent of actual costs to provide the
        Service in question).

Competition

2.12 Nothing in this Agreement shall prevent the LESO from becoming a
distributor of the services of, or holding any economic interest in, any entity
that provides mobile satellite telecommunications services, regardless of
whether such entity competes with the Company.

4.3 or, if the circumstances in Clause 4.4 apply, based on mutually agreed
terms.

4.3 In accordance with the procedures and time schedule set out in Annex F, the
LES Operators and the Company shall enter into negotiations to agree standard
terms and conditions (to apply during an Extended Term as defined below) prior
to the start of the fifth year of the Initial Term. Where standard terms and
conditions are agreed, the LESO shall then decide whether to exercise its option
in Clause 4.2 and shall notify the Company within sixty (60) days after the
conclusion of the meeting described in Annex F. If standard terms and conditions
are not agreed, Clause 4.4 shall apply.

4.4 If the Company and the LES Operators do not agree to standard terms and
conditions to apply during an Extended Term pursuant to the procedures set forth
in Annex F, then the Company and the LESO may negotiate during the fifth year of
the Initial Term to extend the Initial Term for a further fixed period of five
(5) years (the "Extended Term") on mutually agreeable terms and conditions;
provided that any such terms and conditions shall be no less favourable to the
LESO than those provided or offered to other LES Operators.

4.5 The Company may not enter into an agreement with any Affiliate of the
Company for the provision of Services for the Extended Term nor provide Services
itself until such agreements have been concluded with LES Operators providing
thirty (30) percent of the Company"s total revenues derived from all LESO
Agreements in the prior calendar year. Prior to entering into an agreement with
an Affiliate hereunder, the Company shall provide notice to all LES Operators
concerning (i) the Company's total revenues during the prior year; and (ii) the
contribution to the Company's total revenues during the previous year of the LES
Operators with which the Company has concluded agreements for the Extended Term.
Any agreement between the Company and its Affiliate must be approved by the
Board of the Company and must contain the limitations and procedural safeguards
on the actions of the Affiliate that apply to the Company's separate Subsidiary
in Clause 2.9 hereof. This Clause shall survive termination of the Initial Term.

4.6 If an Extended Term is agreed between the Company and the LESO pursuant to
Clause 4.3 or Clause 4.4, provisions similar to those contained in Clauses 2.9
and 7 shall be incorporated in the terms and conditions for such extension. The
terms and conditions shall also incorporate a provision that in the event that
the Company or any Affiliate is permitted to act as a Reseller at any time
during the Extended Term, it shall do



                                       13

<PAGE>

so only through a structurally separate Subsidiary that complies with the
provisions in Clause 2.9 above.

5    SERVICE ACTIVATION AND PROVISION

5.1 The Parties shall make arrangements to permit end-users to use the Services
provided through the Space Segment and the LESO's Land Earth Station. The LESO
shall have full rights and responsibility to establish the service rates at
which the LESO distributes Services to its Resellers and end-users. The Parties
shall cooperate to provide for the minimization of credit risks associated with
the provision of Services to end-users in accordance with this Clause 5.

5.2 The Company shall authorize such number of routing organizations or other
Points of Service Activation as may be necessary to facilitate widespread
activation of end-user MESs, consistent with applicable law, (for the purpose of
this Agreement, each routing organization and other Point of Service Activation
shall be referred to individually as a "PSA", and collectively as "PSAs") and
shall appoint the LESO to act as a PSA, upon the LESO's request and if permitted
by applicable national law, provided, however, that (i) the Company shall impose
on each PSA, as a condition of its appointment, the Points of Service Activation
Criteria in Annex Q and (ii) the LESO, as a condition of such appointment, shall
comply with the Points of Service Activation Criteria in Annex Q. The Parties
acknowledge that, within a particular national regulatory framework, a PSA may
be required to include a national regulatory authority, in which case the term
"PSA", as used hereunder, shall be deemed to include, collectively, such
national regulatory authority and such other entity that complies with the
Points of Service Activation Criteria in Annex Q. The Company shall monitor and
enforce compliance with the Points of Service Activation Criteria throughout the
term hereof.

5.2.1 The Company shall treat all information relating to the identity and
corporate or personal details relating to end-users that the Company receives
from a PSA, including all such information (including commissioning data-bases)
obtained by the Company from the Organization in accordance with the
transactions contemplated in the Master Transition Agreement, as Confidential
Information (within the meaning of Clause 17) hereunder for the benefit of the
LESO and other LES Operators and shall not, without the consent of the LESO and
other LES Operators acting through an LES User Group Meeting, (i) disclose such
information to any third party (other than to maritime safety and distress
rescue agencies for the purpose of assisting in distress and safety missions) or
(ii) allow such information to be provided to the Company's Subsidiary (within
the meaning of Clauses 2.9., 2.10 and 4.5) except on terms that are identical to
those on which such information is provided to the LESO and other LES Operators.



                                       14

<PAGE>


5.3 Following notification by a PSA of a prospective end-user's valid
application for service in accordance with the Points of Service Activation
Criteria in Annex Q, and subject to any procedures as the Company deems
appropriate to verify that the PSA has complied with the criteria and procedures
required hereunder (and the receipt of any other authorization or approval
required under applicable law), the Company shall facilitate the activation of
such end-user's MES by providing in electronic form to the LESO, other LES
Operators and (upon the LESO's-written request) any Authorized Credit
Clearinghouse organized by the LESO or other LES Operators, the MES
identification number, recognized billing entity (including, without limitation,
Accounting Authority code or ISP code), and other information as may be
necessary for service activation of such MES. For the purpose of this Agreement,
the term "Accounting Authority" shall mean an Accounting Authority within the
meaning of ITU-T Recommendation D.90. The Company shall not activate any MES
that is not associated with an ISP or Accounting Authority or other entity
approved by the Company, and which accepts financial responsibility for payment
of end-user charges in a manner consistent with the requirements of the Points
of Service Activation Criteria in Annex Q. With respect to MESs that are
activated prior to the Effective Date, the Company shall use its best efforts to
impose the Points of Service Activation Criteria on any PSA in existence as of
the Effective Date ("Existing PSAs") and shall keep the LESOs informed following
the Effective Date of the identities of any Existing PSA that has not agreed to
the Points of Service Active Criteria (a "non-compliant PSA"). The Company shall
provide without delay to the LESO, immediately upon the presentation by the LESO
of reasonable proof of non-payment by the owner of any MES associated with any
non-compliant PSA, the corporate and personal details of such MES owner for the
LESO's debt collection purposes. Following the date that is one (1) year after
the Effective Date, the Company shall not activate any MES associated with an
Existing PSA that remains a non-compliant PSA, unless the Company has undertaken
the necessary steps to verify the information concerning an MES owner or
operator that is required to be verified by the PSA using the procedures
outlined in Annex Q.

5.4 The LESO shall not activate any MES that has not been authorized through the
Company's service activation procedures, as notified to the LESO from time to
time.

5.5 The LESO shall not be obliged to provide Services to any MES that does not
meet the LESO's own criteria (such as the creditworthiness of the end-user or
responsible billing entity associated with such MES) so long as the LESO does so
in a manner that is consistent with the LESO's obligations to provide distress
and safety service under its national laws and regulations.

5.6 Except as expressly provided to the contrary in Clauses 5.8 and 6 of this
Agreement, the LESO shall be responsible to the Company for payment of all
Charges



                                       15

<PAGE>

arising from the LESO's provision of Services to any MES through the
LESO's Land Earth Station.

5.7 If an MES has been refused access by the LESO in accordance with the LESO's
own criteria (such as creditworthiness of the end-user), and provided that such
MES has not been subject to a mandatory financial bar (as provided for in Annex
A), the LESO shall continue to provide access to such MES for fixed-to-mobile
traffic, but only if it can do so under circumstances in which (i) the LESO is
not exposed to the risk of non-payment associated with such traffic, or (ii) the
MES has no outstanding debt to the LESO.

5.8 In order to achieve the purpose set out in paragraph 1 of Annex A, the
Parties shall implement the financial Barring Procedures set forth in Annex A.
In the event that the Company notifies the LESO of a mandatory financial bar on
an MES in accordance with such procedures, the Company shall impose financial
penalties on the LESO or any LES Operator which violates such bar, including
without limitation any entity that is authorized by the Company to operate an
LES in accordance with Clause 2.7 hereof, and shall impose the same conditions
on the LESO and all LES Operators with respect to the maintenance and lifting of
such bar as provided for in the Barring Procedures set forth in Annex A. In the
event that the LESO provides service to an MES that is subject to a mandatory
financial bar in violation of the requirements of the Barring Procedures, then
the LESO agrees that it shall pay to the Company the penalty Charges provided
for in Annex G. In the event that the Company fails to notify the LESO of the
lifting of a mandatory financial bar under the circumstances required by the
procedures set forth in Annex A, then the Company shall not be entitled to
receive the penalty Charges from the LESO from the date on which the Company
should have provided such notice in accordance with such procedures.

5.9 Notwithstanding the foregoing, in the event that the Company fails to notify
the LESO or the other LES Operators of the implementation of a mandatory
financial bar under the circumstances required by the Barring Procedures set
forth in Annex A, then the LESO shall not be obligated to pay Charges for
Services provided to any MES that would have been subject to the mandatory
financial bar. The Company shall have no other liability for failure to provide
notice of the implementation or lifting of a mandatory financial bar except as
expressly provided for in this Clause 5.

6    TECHNOLOGICAL FRAUD MANAGEMENT

6.1 The Parties shall use their best endeavours to eliminate economic losses,
and inconvenience to legitimate end-users, arising from technological fraud,
such as, without limitation, the cloning of MESs and theft of MES identification
codes. The Company shall



                                       16
<PAGE>


use its reasonable endeavours to develop and implement
where possible technical means for detection and prevention of such
technological fraud (such as MES fingerprinting).

6.2 The LESO shall have no obligation to pay Charges for Services in cases where
the LESO has unknowingly carried traffic to or from an MES through which
technological fraud has been perpetrated, provided that the LESO shall
immediately notify the Company in the event that the LESO knows or suspects that
a particular MES is fraudulent or is being fraudulently operated and shall
provide reasonable proof to the Company that fraud has occurred.

6.3 The LESO shall comply with the Technological Fraud Prevention Procedures set
forth in Annex R, as amended from time to time in accordance with Clause 20.

6.4 Notwithstanding the foregoing, the LESO shall have an obligation to pay
Charges under the circumstances outlined in Clause 6.2 in the event that (i) the
LESO receives non-refundable payment for the Services provided from the end-user
in question; or (ii) the LESO provides Services to the MES in question after the
Company informs the LESO that the Company has reason to believe that such MES is
fraudulent or is being fraudulently operated, or (iii) the LESO's failure to
comply with the Technological Fraud Prevention Procedures in Annex R has allowed
such technological fraud to take place.

6.5 The LESO shall not provide Services to an MES that the LESO knows or has
reason to believe is fraudulent or fraudulently operated.

6.6 The Parties shall assist legitimate end-users whose MESs may be compromised
by technological fraud, including (i) on the LESO's part (with the assistance of
the Company upon the LESO's request), contacting such end-users or Resellers to
inform them of the existence of the fraud; (ii) assisting such end-users with
deactivation and reactivation of their MESs with new access numbers and codes
and any other relevant facilities and (iii) providing general information
concerning fraud avoidance. In the event that an end-users MES must be
deactivated and reactivated as the result of technological fraud arising from
the LESO's failure to comply with the Technological Fraud Prevention Procedures
in Annex R, then the LESO shall reimburse the Company for administrative costs
associated with such deactivation and reactivation and reasonable costs incurred
by the end-user in connection therewith (provided that such costs shall be
demonstrated to be reasonably incurred).

7    RENEWAL OF THIS AGREEMENT

7.1 This Agreement may be renewed upon the expiry of the Extended Term on any
terms and conditions as may be mutually agreed between the Company and the LESO.



                                       17
<PAGE>


In order to facilitate the orderly renewal of this Agreement, the Parties agree
to comply with the procedures described in this Clause provided, however, that
neither Party shall be under a binding obligation to agree to any renewal of
this Agreement and nothing in this Clause shall preclude the Parties from
mutually agreeing to any other procedure for the negotiation and execution of
such renewal.

7.2 If, not less than eighteen (18) months before the expiry of the Extended
Term, the LESO, gives the Company written notice requesting the renewal of this
Agreement, the Company shall, at least fifteen (15) months before such expiry,
give the LESO written notice stating either the terms and conditions upon which
the Company is willing to grant a renewal to the Agreement pursuant to this
Clause or that the Company is not willing to grant such renewal and the reasons
for such decision. If the Company is willing to grant a renewal, the Parties
shall each use their best efforts to conclude any agreement for renewal at least
twelve (12) months before the expiry of the Extended Term. In considering the
request for a renewal, the Company shall, consistent with the objects set forth
in its Memorandum of Association, take into account the desirability of the LESO
continuing to provide Maritime Distress and Safety Services.

8    AUTHORISATION SUBJECT TO COMPLIANCE

8.1 Subject to Clause 8.4 below, the Authorisation shall be conditional upon
compliance by the LESO with the LES Technical Criteria and Operating Procedures
in respect of all Services being provided by the LESO, or by a Reseller using
the LESO's Land Earth Stations. The LESO shall also use reasonable endeavours to
comply with the minimum LES Technical Performance Objectives in Annex M. Subject
to Clauses 8.4 and 20, the Company shall apply the same LES Technical Criteria
and Operating Procedures to all LES Operators for Services provided through the
Land Earth Stations of such LES Operators.

8.2 If the LESO fails to comply with its obligations under Clause 8.1:

(i)     The Company shall give notice to the LESO requiring its non-compliance
        to be remedied within a reasonable time (which shall not be less than
        ten (10) days except in Urgent Operational Cases) taking into account
        all of the circumstances, and after consultation with the LESO.

(ii)    If the non-compliance continues after the time specified in the
        Company's notice in sub-paragraph (i), the Company shall have the right,
        with immediate effect:

        (a)  to suspend the Authorisation for non-compliant
             Services in respect of the LES or LESs concerned; or


                                       18
<PAGE>

        (b)  to suspend the Authorisation with respect to any tenant entity in a
             Shared LES Agreement with the LESO in the event that such
             non-compliance is caused by the tenant entity; or

        (c)  to suspend the entire Authorisation where the non-compliance
             affects all the Services provided and all of the LESs operated by
             the LESO.

(iii)   Notice of suspension shall be given by the Company to the LESO
        immediately after any such action and such suspension shall continue
        until the date on which the LESO resumes compliance with the LES
        Technical Criteria and Operating Procedures, as determined by the
        Company acting in good faith.

(iv)    This Sub-Clause 8.2 shall be without prejudice to the applicable
        provisions of Clause 21.

8.3  Notwithstanding the foregoing and subject to the provisions of Clause
8.2(iii) above, the Company shall have the right to suspend the Authorisation
with respect to Services provided, or Land Earth Stations operated, by the LESO
without notice in the event that such Services or Land Earth Stations are not
compliant with the requirements of the LES Technical Criteria and Operating
Procedures and such failure of compliance has led to the occurrence of an Urgent
Operational Case.

8.4  The obligation of the LESO to comply with the requirements of the LES
Technical Criteria and Operating Procedures shall be subject to any waivers from
compliance with such requirements granted by the Organization to the LESO. In
addition, the Company may grant waivers to the LES Technical Criteria and
Operating Procedures after the Effective Date of this Agreement, provided that
any such waiver (or a functionally equivalent waiver) that is granted to other
LES Operators shall be granted to the LESO if the LESO demonstrates similar
hardship in similar circumstances. Upon request by the LESO at the time that the
LESO seeks a waiver, the Company shall disclose the existence of waivers granted
to other LES Operators that are similar to the waiver requested by the LESO. 9
9    CHARGES

9.1 The LESO shall pay to the Company, subject to the provisions of this Clause
9, the Charges calculated in accordance with Annex G for services via the Space
Segment provided hereunder to the LESO by the Company (as such Charges may be
adjusted from time to time in accordance with Clauses 9.5 and 9.6). The LESO
shall be responsible for the payment of all Charges to the Company for all
Services that are provided via the Space Segment using its LES (including those
Services provided by Resellers). The Charges



                                       19

<PAGE>


shall be paid to the Company in US dollars or in any other freely convertible
currency that is acceptable to the Company and otherwise in accordance with
the invoice procedures in Clause 10.

9.2 The Company may offer price incentives to the LESO and other LES Operators,
as set forth below:

A.      Performance Incentives. The Company shall be free to introduce price
        -----------------------
        incentives based on the contribution of the LESO and other LES Operators
        in meeting performance objectives defined by the Company with the aim of
        expanding the overall traffic or customer base for the Services,
        provided that any such price incentives are made available to all LES
        Operators based on the same criteria.

B.      Take-or-pay and Modified Take-or-pay. The Company shall be
        -------------------------------------
        free to introduce further price incentives based on firm
        commitments by the LESO to deliver a specified volume of
        traffic for a defined Service over a specified period of
        time, and, where the Parties determine that such an
        arrangement would be desirable, to modify the take-or-pay
        commitment such that the penalty amount payable by the
        LESO for any shortfall in traffic delivered is an agreed
        fraction of the actual shortfall amount. Any such
        take-or-pay or modified take-or-pay commitments shall be
        offered by the Company to all LES Operators on an equal
        basis at least thirty (30) days prior to the introduction
        of such scheme for any LES Operator, subject to the
        availability of Space Segment capacity.

Taxes and Tax Credits

9.3 All Charges payable by the LESO under this Agreement shall be paid free and
clear of all taxes, levies, duties, costs, charges, withholdings, deductions or
any charges of equivalent effect (tax or taxes) imposed on the Services by any
authority having the power to impose such taxes, provided that the Company shall
remain responsible for any income tax imposed on it.

9.4 If, and to the extent that, the LESO pays a tax in accordance with Clause
9.3 and the Company receives and retains the benefit of a refund of a tax or
credit against tax on its overall net income which is attributable to the tax
paid by the LESO (a Tax Credit), then the Company shall reimburse such amount to
the LESO or, at the LESO's option, the LESO may deduct the applicable amount
from amounts payable to the Company in accordance with Clause 10. The LESO may
identify a Tax Credit for which the Company may be eligible and assist the
Company in claiming such Tax Credit. The Company shall use reasonable endeavours
to claim any such Tax Credit to the fullest extent permitted by


                                       20

<PAGE>

applicable law. In the event that the LESO claims a reimbursement hereunder, the
LESO shall identify any such Tax Credit to the Company and provide all necessary
information and assistance to the Company to claim such Tax Credit. In the event
of an audit by any relevant taxing authority related to taxes (other than income
taxes) or Tax Credits related to the Services provided by the LESO, the Parties
shall provide such information to each other as may be necessary to comply with
such audit, subject only to limitations imposed by law.

Changes to the Charges

9.5 The Charges set forth in Annex G shall be modified each year of the Term on
the date that is the anniversary of the Effective Date (a "Modification Date")
in accordance with the following formula:


                                    [FORMULA]


where:

        j   =  price component (including both fixed and variable
               components);

        t   =  year following the Modification Date;

        t-1 =  year ending on the Modification Date;

        t*  =  year extending from fifteen (15) calendar months prior to the
               Modification Date to three (3) calendar months prior to the
               Modification Date (the "Measurement Year");

        Vj,t*= volume of component j in the Measurement Year t*; and

        Pj,t = wholesale price of component j in year t (US dollars of year t),
             which shall be undiscounted except as permitted under Article
             9.6.3.

9.6.1 At least thirty (30) days before the Modification Date, the Company shall
provide to the LESO the following information:

(i)     the Charges (for each price component, i.e. for
        Demand-Assigned Services, Full-Period Services and Fixed
        Charges) during the year ending on the Modification Date;



                                    21

<PAGE>

(ii)    the total Service volumes of the Company (for each price component)
        during the Measurement Year;

(iii)   the calculation of Charges for the year commencing on the Modification
        Date in accordance with the formula in Clause 9.5 and shown in
        sufficient detail that the LESO can verify the calculation based on the
        information supplied in accordance with (i) and (ii); and

(iv)    a report from the Company's auditors stating that in their opinion the
        information supplied in accordance with (i) to (iii) fairly presents the
        revenues earned by the Company and the application of the formula in
        Clause 9.5.

The Company shall provide the information required in paragraphs (i) to (iv) to
the LESO in a manner and at location(s) that protect the confidentiality
thereof. The Parties agree that all such information provided shall be deemed to
be Confidential Information and shall be protected as required by Clause 17 of
this Agreement.

9.6.2 The Company shall be free on a Modification Date to adjust the Charges of
any individual Service and to adjust the fixed and variable components of any
Charge for any individual Service, so long as the formula in Clause 9.5 is
satisfied.

9.6.3 In implementing the formula in Clause 9.5, the Company shall not take
account of Charges or volumes that are based upon take-or-pay, or modified
take-or-pay commitments between the Company and individual LES Operators
pursuant to Clause 9.2B unless such commitments are expressly set forth in Annex
G.

9.6.4 In the event that the Company adds Evolved Services to Annex G in
accordance with this Agreement, then any such Services shall be subject to the
price formula in Clause 9.5 on any Modification Date failing more than six (6)
months after the date on which the Service is added to Annex G.

9.6.5 In the absence of an arithmetic or other clerical error in the application
of the formula in Clause 9.5, the new Charges developed by the Company as
revised to reflect the requirements of Clause 9.5 shall be final and binding on
the Parties and shall not be subject to dispute under Clause 30 of this
Agreement. The Company shall provide to the LESO a revised Annex G reflecting
the new Charges at least ten (10) days before the Modification Date, and such
revised Annex shall constitute an amendment to this Agreement.

Introduction of New Charges


                                    22


<PAGE>

9.7 If the Company introduces an Evolved Service for which no Charge is listed
in Annex G as of the Effective Date, the Company shall establish the initial
Charge for that Service, subject to prior consultation with the LESO. Once such
a Charge is established, Annex G shall be modified accordingly and the Charge
shall be subject to Clauses 9.5 and 9.6, provided that the Company shall be free
at any time to offer reduced promotional levels of Charges on a temporary basis
to facilitate the introduction of newly-offered Services, provided further,
however, that the Company shall notify the LESO in advance of the period of
validity of any such promotional Charge and that the Company may not increase
the promotional rate more than one time to establish the "initial Charge" under
Annex G.

Non-discrimination

9.8 In establishing Charges, the Company will not discriminate on the basis of
the nationality of LES Operators. Notwithstanding the foregoing, the Company
shall have the right to offer different Charges for the same Service in defined
geographical regions in which end-user calls or messages originate or terminate
and which are technically verifiable, provided that (i) every LES Operator that
provides such Service in the relevant defined (and technically verifiable)
geographical region shall be entitled to receive such Charge; (ii) consistent
with this Clause 9, the Company shall modify Annex G as necessary to reflect
such price differentiation(s) on an ongoing basis and publish the same to every
LES Operator, and (iii) the Company may implement differential prices only if it
is consistent with the Company's obligation under applicable law.

9.9 For the purpose of determining the amount of payments due under Clause 10
hereof, the LESO's use of the Space Segment for provision of the Services shall
be measured in accordance with the procedures set forth in Annex H.

10 PAYMENT OF CHARGES

10.1 With respect to Demand-Assigned Services as set out in Part A of Annex G,
excepting invoices for volume commitments, the Company shall invoice the LESO on
a monthly basis. Each invoice shall be dated as of the day that it is produced
and shall be sent by courier to the LESO on that date. All invoices for a
calendar quarter shall be due for payment sixty (60) days after the date of the
last invoice for that calendar quarter (Payment Due Date). Each invoice shall
contain a traffic statement for the month covered by the invoice prepared in
accordance with Clause 9.9. Each traffic statement shall include a summary of
traffic volume by Service per LES in units of minutes or kilobits (with separate
details for chargeable and non-chargeable traffic), details of the Charges for
each Service and the total amount in US dollars due to the Company.


                                       23

<PAGE>


10.2 With respect to invoices for volume commitments, the Company shall
ordinarily invoice the LESO at least thirty (30) days in advance of the period
to which the volume commitment refers to. Each invoice shall be dated as of the
day that it is produced and shall be sent by courier to the LESO on that date.
Each invoice shall be due for payment on the last business day prior to the
period to which the volume commitment refers (Payment Due Date).

10.3 With respect to Full Period Services and Fixed Charges as set out in Part B
of Annex G, the Company shall ordinarily invoice the LESO at least thirty (30)
days in advance of the start of the period to which the service refers. Each
invoice shall be dated as of the day that it is produced and shall be sent by
courier to the LESO on that date. Such services shall be due for payment in full
on the last business day prior to the start of the period to which the service
refers (Payment Due Date).

10.4 An interest charge shall be imposed, at a rate of the current three (3)
month US dollar London Inter-Bank Offer Rate (LIBOR) plus twelve (12) percentage
points per annum calculated daily, on any payment due under this Agreement
remaining unpaid after the Payment Due Date. Such interest charge shall be
computed commencing on the first day following the Payment Due Date.

10.5 Any payment to be made under this Agreement shall be made by wire transfer
directly to the bank account designated by the Company in writing and shall be
deemed to be received by the Company on the date the amount is credited to the
Company's bank account.

10.6 If any payment required under this Agreement has not been received by the
Company by the Payment Due Date, the Company may serve a written demand for
payment. Subject to Clauses 10.7-10.9, if the payment to which such written
demand refers remains outstanding for thirty (30) days following receipt of such
written demand, the Company may suspend the Authorisation. In the case where
payment remains outstanding for more than ninety (90) days after the date on
which the Company becomes entitled to suspend the Authorisation, the Company
shall have a right to terminate the Agreement in accordance with Clause 22.1.

Invoice disputes

10.7 The LESO shall notify the Company as soon as possible but no later than
thirty (30) days after the receipt of an invoice in the event of any dispute
regarding the Charges payable by the LESO, to the Company for the provision of
Services via the Space Segment. The Company and the LESO shall enter into
discussions and shall use their best efforts, including reciprocal provision of
relevant records, to resolve disputes within ninety

(90) days from the date of receipt of the invoice. In the event that, as a
result of such discussions, it is determined that the LESO should pay any amount
to the Company, the LESO shall pay interest to the Company in the amount set
forth in Clause 10.4 for any amounts paid after the Payment Due Date
notwithstanding initiation of such discussions. Any such notice in writing shall
include the reasons for the dispute and a preliminary quantification of the
disputed amount by means of a comparison of the Company's traffic statement
underlying the invoice, or part thereof, with the LESO's own call data records.

10.8 The LESO shall pay the undisputed amount of any invoice by the relevant
Payment Due Date. In the event that the Parties are unable to resolve a dispute
concerning all or a portion of an invoice within the ninety (90) day period set
forth in Clause 10.7, then such dispute will be deemed to be a formal dispute.
In the event of a formal dispute, the Company and the LESO, acting through their
respective chief financial officers (or their designates), shall act in good
faith to attempt to resolve the dispute within thirty (30) days following
initiation of the formal dispute.

10.9 In the event that the Company and the LESO are unable to resolve the formal
dispute in accordance with Clause 10.8 within the thirty (30) day period
specified therein, the dispute shall be determined by an expert in accordance
with Clause 30.2. Where any payment made in accordance with Clause 10.8 has
resulted in either an underpayment or an overpayment by the LESO, such
underpayment or overpayment shall be paid by the LESO or refunded by the
Company, as appropriate, including accrued interest calculated in accordance
with Clause 10.4 from the Payment Due Date (if the payment is made by the LESO)
or from the later of the date of the overpayment by the LESO or the Payment Due
Date (if the payment is made by the Company), within fourteen (14) days of the
determination resolving the dispute.

Non-availability of Third Generation Satellites




                                       28
<PAGE>

13.6 If, for any reason, a Third Generation Satellite at one of the locations
described in Clause 13.3 ceases to operate or, if the capacity on that Satellite
is permanently or indefinitely degraded, or if the capacity is or becomes
insufficient to satisfy all the LESO's traffic requirements at any time, the
Company shall use its reasonable endeavours to replace or augment the capacity
in conformity with the Network Performance Objectives referred to in Annex N in
the Ocean Region concerned by using one or more of the following means available
to it, depending on the operational circumstances:

(a)   Use of a fifth Third Generation Satellite

        If a Third Generation Satellite whose location is specified in Clause
        13.3 ceases to operate or becomes permanently or indefinitely degraded,
        the primary means of providing replacement capacity shall be the
        deployment of the fifth Third Generation Satellite to the location
        concerned (as defined in Clause 13.3), if the fifth Third Generation
        Satellite is functioning normally and if it has not already been
        deployed to one of the locations defined in Clause 13.3.

(b)   Use of a Second Generation Satellite

      (i)    If a fifth Third Generation Satellite is not
             available for the purpose mentioned in sub-paragraph
             (a), either the adjacent Second Generation Satellite,
             if any, shall be used, or a Second Generation
             Satellite shall be deployed at the location
             concerned, in order to provide capacity for the
             Services to the maximum level available on the Second
             Generation Satellite, subject to the availability of
             sufficient fuel to enable such deployment to be made.
             The Company may, in its discretion, deploy more than
             one Second Generation Satellite for that purpose.

      (ii)   The Parties acknowledge that Second Generation Satellites have
             limited capacity compared to Third Generation Satellites and cannot
             carry Services designed solely for spot-beam operation.

(c)     The maximum time needed to relocate a Second or Third Generation
        Satellite for the above purposes shall be thirty (30) days, subject to
        the availability of sufficient fuel to effect the relocation within that
        time and maintain station-keeping after the relocation.

(d)   Capacity Augmentation

        (i)  If capacity on a Third Generation Satellite is or becomes
             insufficient to carry the LESO's traffic requirements at any
             time, although the Satellite





                                       29
<PAGE>


             is functioning nominally, the Company may optimise Space Segment
             capacity using the general guidelines in Annex I. Except in an
             Urgent Operational Case, the Company shall consult with the LESO
             prior to taking any such measures.

      (ii)   If capacity on a deployed Second Generation Satellite or Satellites
             used in accordance with paragraph 13.6 (b), is insufficient to
             carry the nominal traffic load in accordance with the Network
             Performance Objectives in Annex N, the Company may optimise the
             capacity of any such Satellites using the general guidelines set
             out in Annex I. The nominal traffic load in this context means the
             average bouncing busy hour volume of traffic for particular
             Services that had been carried by the Third Generation Satellite
             concerned during the three (3) months immediately prior to the
             start of the use of the Second Generation Satellites under
             paragraph 13.6 (b). Except in an Urgent Operational Case, the
             Company shall consult with the LESO prior to taking any
             optimisation measures.

      (iii)Alternatively to sub-paragraphs 13.6 (d) (i) and (ii), in order to
             augment capacity in the Ocean Region concerned so as to accommodate
             the LESO's traffic requirements, the Company may deploy an
             additional Second or Third Generation Satellite to that Ocean
             Region, at an orbital location determined by the Company from
             amongst the locations defined in Clause 13.5. The LESO may elect to
             operate on one or both Satellites in that Ocean Region.

(e)   Consultations with LESO
      ------------------------

        The Company shall notify the LESO of the occurrence of any of the above
        events. Except in an Urgent Operational Case, the Company shall consult
        with the LESO before taking any of the above actions. The consultations
        and subsequent actions by the Company shall take into account the need
        to preserve coverage for the LESO and all other LESO Operators and also
        the need to ensure continuity of Maritime Distress and Safety Services
        and any other safety-related communications services.

Company's Right to Replace Capacity

13.7 Subject to the requirements of Clause 13.6 and the Network Performance
Objectives in Annex N, the Company shall have discretion to interchange any of
the Third Generation Satellites at any of the locations referred to in Clause
13.3 or to interchange




                                       30
<PAGE>


any of the Second Generation Satellites at any of the locations referred to in
Clause 13.5 in the light of joint interests of the Company and all LES
Operators.

13.8 Except in an Urgent Operational Case, the Company shall give the LESO
reasonable prior notice of any proposed replacement of a Satellite, and shall
consult with the LESO prior to such replacement, and take into account any
reasonable request made by the LESO in relation to the proposed replacement.

Use of Spare Capacity of Second and Third Generation Satellites

13.9 The use of spare capacity on any Satellite not required by any LES Operator
for the provision of Services shall be at the discretion of the Company. Leasing
of capacity shall be subject to the Company's lease policy, described in Annex
E, as may be modified by the Company from time to time.

Operations Infrastructure

13.10 The Company shall provide, or shall procure the provision of, the
operations infrastructure necessary to support the operation of the Satellites
through which the Services are provided, and shall use its reasonable endeavours
to achieve the Network Performance Objectives set out in Annex N.

Liability

13.11 Other than as provided for in Clause 13.12, the Company shall not incur
any financial liability to the LESO if the performance of any of the Satellites
or of the operations infrastructure fails to achieve the Network Performance
Objectives specified in Annex N.

13.12 In the event that the Company fails to meet the minimum Network
Performance Objectives set forth in Annex N, then the LESO shall receive outage
credits for any traffic commitment or other fixed-period service affected by
such outage as follows: No allowance or credit will be made for any
unavailability, delay or interruption in the availability of the service which
is of less than one hour's duration. Any such unavailability, delay or
interruption which is of one hour or more duration shall be credited to the LESO
in an amount equal to the proportionate charge in one hour multiples for each
one hour, or major fraction thereof during which such unavailability, delay or
interruption has occurred. In addition to the foregoing, in the event that the
Company relocates a Satellite or substitutes a Satellite of one generation with
a Satellite of another generation and, as a result thereof, the LESO is unable
to meet a traffic commitment that it undertakes prior to such relocation or
substitution, then the LESO shall be excused from such traffic commitment.

15    DISCLAIMERS OF LIABILITY

Telecommunications Breakdown and Application of Barring Procedures

15.1 Subject to this Clause 15, the LESO agrees that the Company (for itself and
as trustee for the benefit of the other indemnitees, as defined in Section 15.8)
shall not be liable on any basis whatsoever to the LESO, its Affiliates,
Resellers, customers or other end-users for any direct, indirect or
consequential loss, damage or expense, including, without limitation, loss of
profits or revenues, loss of distribution rights, abortive expenditure or damage
to property and injury or death to persons, arising from or in connection with
(i) any Telecommunications Breakdown, regardless of cause including, but without
limitation, satellite or other equipment failure or malfunction, or any
unavailability, delay or interruption of telecommunication services caused as a
result thereof, or (ii) any suspension of service to a mobile earth station
resulting from actions by the Company acting in good faith at the request of the
LESO or other LES Operators in accordance with the Barring Procedures.

15.2 Notwithstanding Clause 15.1, the Company shall compensate the LESO for loss
in the event that the Telecommunications Breakdown described in Clause 15.1
above is caused by the wilful or reckless act or knowing or reckless omission of
the Company in circumstances where the Company knew that such act would have
such effect or was reckless as to whether or not such act or omission would have
such effect.

15.3 In the event of the Company becoming liable in accordance with Clause 15.2
to compensate the LESO, the loss suffered by the LESO shall be deemed to be, and
limited





                                       33

<PAGE>

to, a proportionate part of the LESO's relevant net revenues (as defined
in Clause 15.4) calculated by reference to each hour or fraction of an hour
(being not less than one quarter) during the period of time in which the
Telecommunications Breakdown occurred. The Company shall pay such amount to the
LESO, provided that in no circumstances shall the aggregate amount payable by
the Company to the LESO and all other LES Operators affected by such
Telecommunications Breakdown under this Clause 15.3 in respect of all
occurrences or series of occurrences arising out of the same proximate cause in
any calendar year, exceed U.S. $10 million. In calculating the amount payable,
account will be taken of variations in the volumes of traffic at different times
based on the average diurnal profile for the Ocean Region in which the LESO is
located.

15.4 For the purpose of Clause 15.3, the term "LESO's relevant net revenues"
means the LESO's proportional share (based on overall system traffic) of the
gross revenues received by all LES Operators affected by such Telecommunications
Breakdown from the provision of Services by all affected LES Operators during
the twelve (12) months preceding the first incident giving rise to the claim
less (i) the amount of Charges that were payable to the Company in relation to
such revenues and (ii) the variable land-line charges associated therewith
(subject to the $10 million limitation set forth in Clause 15.3).

Disclaimers to be Passed on to End-Users

15.5

(a)   The LESO shall incorporate, and require that Resellers
        incorporate, in the terms and conditions applicable to any
        customers to which the LESO or its Resellers provide
        Services following the Effective Date, disclaimers of
        liability substantially similar to (but in no case less
        broad than) that set forth in Clause 15.1 in favour of the
        Company, the Company's Affiliates and itself. Such
        disclaimers shall be in form or substance consistent with
        the disclaimer set forth in Annex J, or as close to such
        form as is permitted by the applicable law.

(b)   The Company shall, through the PSA, procure that any
        end-user of the Services, as a condition of service
        activation, must sign a written waiver of liability
        vis-a-vis the Company and the LESO (or all LES Operators
        collectively) for any loss, damages or associated costs
        arising in connection with the provision of Services to
        the maximum extent to which the Company and the LESO are
        legally permitted to waive such liability.

Damage to Space Segment or Loss of Services

<PAGE>



15.6 The LESO shall be liable to the Company, and shall indemnify and hold the
Company harmless vis-a-vis claims by any third party (including but not limited
to other LES Operators) against the Company, for any loss or damage to the Space
Segment caused by any act or omission of the LESO, its Resellers, contractors,
employees, agents, lessees or assignees, or any of them (which in no case shall
exceed $100 million in any calendar year), except that the LESO shall have no
liability to the Company for loss or damage arising out of the provision of
Services by the LESO via the Space Segment in a manner authorised by this
Agreement (subject to Clause 8.4), the LES Technical Criteria and Operating
Procedures or as otherwise authorised in writing by the Company.

15.7

(a)     Nothing in this Agreement shall exclude or limit the liability of either
        Party for death or personal injury resulting from such Party's own
        negligence in any jurisdiction where, as a matter of law, such liability
        cannot be excluded or limited.

(b)     Neither Party shall be liable for any indirect, special, punitive,
        incidental or consequential damages arising out of or under this
        Agreement.

Indemnities

15.8 As used in this Clause 15, the term the other indemnitees mean any
Affiliate, or director, officer, employee or agent of an Indemnified Party (as
defined below) or of its Affiliate.

15.9 Either Party (the "Indemnifying Party") shall indemnify the other Party
(the Indemnified Party") and the other indemnitees from and against any direct,
or indirect loss, damage, liability or expense arising from any claim by a third
party, pursuant to or in connection howsoever with:

(a)     any libel, slander, or invasion of privacy or any allegation
        thereof by the Indemnifying Party, its Affiliates,
        Resellers or customers, as the case may be, arising in
        connection with the provision of Services via the Space
        Segment (provided that, for the purpose of this Agreement,
        other LES Operators shall not be deemed to be the
        "customers" of the Company and the Company shall not be
        obligated to indemnify the LESO for claims arising
        hereunder that are attributable to another LES Operator);
        or
(b)     any infringement or alleged infringement of any patent,
        copyright, design, trademark or other industrial or
        intellectual property rights whatsoever of any other
        person by the Indemnifying Party, including without
        limitation, infringement or alleged infringement arising
        in connection with combining or using in




                                       35


<PAGE>

        connection with the provision of Services via the Space Segment as
        authorised hereunder, any apparatus and systems of the
        Indemnifying Party, its Affiliates, Resellers or customers
        (provided that, for the purpose of this Agreement, other
        LES Operators shall not be deemed to be the "customers" of
        the Company and the Company shall not be obligated to
        indemnify the LESO for claims arising hereunder that are
        attributable to another LES Operator).

Notwithstanding the foregoing, neither Party shall be under any obligation to
indemnify the other Party or the other indemnitees of the other Party under this
Clause if any such claim would have arisen against the Party seeking
indemnification under this Clause 15 regardless of the alleged acts or omissions
of the Party from which indemnification is sought or those of its Affiliates,
Resellers or customers.

15.10 The LESO shall indemnify the Company and the other indemnitees from and
against all direct or indirect loss, damage, liability or expense arising from
any claim by any third party resulting from or arising in connection with any
event which is required to be disclaimed under Clause 15.5 hereunder. For the
purpose of this Clause 15.10, the LESO shall be deemed to be the Indemnifying
Party and the Company shall be deemed to be the Indemnified Party.

Defence of Indemnified Claims

15.11 With respect to any claim for damage or loss that is required to be
indemnified hereunder, the indemnifying Party shall, at its own expense, defend
any such claim subject to the conditions that the Indemnified Party (or, as the
case may be, the other indemnitees) shall give the Indemnifying Party reasonable
notice of the receipt of any such claim, and provide such cooperation to the
Indemnifying Party as is reasonably necessary for the defence of the claim,
including, without prejudice to the generality of the foregoing, the filing of
all pleadings and other court processes, the provision of all relevant
information and documents, and providing reasonable access to relevant
employees.

15.12 If, in the event of any claim subject to Clause 15.11, the applicable law
does not permit the Indemnifying Party to defend the claim as contemplated
herein, then the Indemnified Party shall conduct its defence under instructions
from the Indemnifying Party and shall not make any admissions, settlements or
compromises without the written consent of the Indemnifying Party.

15.13 The provisions of Clause 15.6 to Clause 15.12 regarding indemnification
shall survive the expiration or termination of the Agreement.

16    INSURANCE



                                       36
<PAGE>


16.1 The Company and the LESO shall each maintain liability insurance from a
third party insurer or self-insurance in an amount sufficient to cover the
indemnities which each Party has granted, respectively, under this Agreement, to
the other Party. Each Party shall, upon request of the other Party, provide the
other Party with evidence of such insurance or, as the case may be, net asset
value that is sufficient to cover the indemnities granted under this Agreement.

16.2 In addition to the insurance described in Clause 16.1, the Company shall
obtain and maintain insurance (in a commercially reasonable amount that is
standard for the satellite communication services industry) to cover third party
claims resulting from telecommunications breakdown of any nature whatsoever that
relates to the availability of the Space Segment. At its option, the LESO shall
be named as an additional insured on such policy, in which event, the LESO may
be required to contribute, along with other LES Operators, to the cost of such
insurance policy. Any such contribution will become payable within thirty (30)
days of the date of the receipt by the LESO of an invoice from the Company. The
Company shall also provide such other information about such insurance policy as
the LESO may reasonably request.

17    CONFIDENTIALITY

17.1

(a)     The Company and the LESO hereby agree that it may be
        necessary to the performance of this Agreement for a Party
        (the "Disclosing Party") to disclose to the other Party
        (the "Receiving Party") certain information that the
        Disclosing Party deems to be confidential and proprietary.
        The Receiving Party shall maintain the security and
        confidentiality of all Confidential Information (as
        defined below) received from the Disclosing Party
        hereunder.

(b)    For purposes hereof "Confidential Information" shall include
        (i) information deemed to be Confidential Information
        under Clause 5.2.1, and (ii) technical information,
        customer lists and other business information or data
        relating to the Disclosing Party, its Affiliates or other
        representatives that is reduced to writing and marked
        "Confidential" or with a similar designation by the
        Disclosing Party. Notwithstanding anything contained
        herein to the contrary, Confidential Information shall not
        include (i) information developed independently by the
        Receiving Party or lawfully received from a third party
        not under an obligation of confidentiality; or (ii)
        information in the public domain; or (iii) information
        disclosed pursuant to law, judicial order or governmental
        regulation.



                                       37

<PAGE>

(c)     The Receiving Party shall not use or communicate, directly or
        indirectly, any of the Confidential Information to any third party
        without the prior written consent of the Disclosing Party. The Receiving
        Party shall use its best efforts to prevent inadvertent disclosure of
        all or any part of the Confidential Information to any third party.

17.2 The Company shall treat all information that the Company receives from the
LESO specifically relating to the LESO's customers or Resellers as Confidential
Information hereunder and shall use such information only for the purpose
intended by the LESO. The Company shall not, without the written consent of the
LESO, disclose such information to any third party (including any other LES
Operator) or (i) allow such information to be provided to the Company's
Subsidiary (within the meaning of Clauses 2.9, 2.10 and 4.5), or (ii) to any
governmental, international or intergovernmental agency or authority, unless
required by law.

17.3 Notwithstanding anything else in this Agreement, the obligations contained
in this Clause 17 shall survive the termination or expiration of this Agreement
for a period of three (3) years.

18     INTELLECTUAL PROPERTY

18.1 The Company represents and warrants that it owns or has a valid license to
use, certain patents, trade secrets, copyrights and other intellectual property
embodied in the LES Technical Criteria and Operating Procedures. This Agreement
confers upon the LESO the right to enter into a royalty-free license agreement
with the Company, the form of which is set forth in Annex U (IPR License
Agreement) (as amended from time to time to cover Evolved Services offered by
the LESO), to use such patents, trade secrets, copyrights or other intellectual
property embodied in the LES Technical Criteria and Operating Procedures as may
be necessary for the LESO to provide Services in accordance with the terms and
conditions of this Agreement and shall provide no other rights of ownership or
of use unless otherwise expressly provided for herein or as otherwise mutually
agreed by the Parties.

18.2 The Company represents and warrants, and the LESO acknowledges and agrees,
that the Company owns or has authority to use or to sub-license the Marks set
forth in Annex S. The LESO shall not obtain any ownership interest in or any
license to use the Marks, except as provided for in the Trademark License
Agreement, a form of which is set forth in Annex T, which the LESO and the
Company have executed on the Effective Date. The LESO shall have no authority to
authorise any Reseller, Customer, agent or other entity to use the Marks, except
as expressly permitted by the Company in



                                       38

<PAGE>

an executed license agreement between the Company and such Reseller, customer,
agent or other entity.

19    TIME LIMITS

      Any period of time referred to in this Agreement shall be counted from the
day following the event marking the start of the period of time and shall end on
the last day of the period laid down. When the last day of a period of time is
not a Business Day, the period shall be extended to the next Business Day.

20    AMENDMENTS

20.1 The terms and conditions of this Agreement shall not be amended or modified
in any manner by the Parties except if such amendment or modification is part of
an agreed change to standard terms and conditions applicable to all LES
Operators or as otherwise expressly provided for herein.

20.1.1 The Company or the LESO may at any time propose an amendment to this
Agreement, including its Annexes, except where express provision is otherwise
made for amendment to any provision of this Agreement or to any Annex. Any such
proposal shall be promptly circulated by the Company to all LES Operators. If at
least three LES Operators so request, or if the Company so decides, the Company
shall convene a meeting open to all LES Operators to consider the proposal. If
the proposed amendment or addition is agreed to in writing by the Company and by
at least two-thirds of the LES Operators providing between them at least
two-thirds of the Company's total revenues derived from all LES Operator
Agreements in the twelve (12) months immediately preceding the date of the
circulation of the proposal, the amendment shall take effect in this Agreement
and all other LES Operator Agreements, on a date to be determined by the Company
and the LES Operators which agree to the amendment.

20.2 Notwithstanding Clause 20.1, the LES Technical Criteria and Operating
Procedures may be amended from time to time by the Company subject to and in
accordance with the provisions of this Clause 20.

20.3 Save as provided in Clause 20.6, the Company shall not adopt any change or
addition to the LES Technical Criteria and Operating Procedures without first
convening a LES User Group Meeting, in accordance with the procedures set out in
Annex K, provided however that the Company shall not be obligated to convene
such a meeting if it is not requested by a minimum of two (2) LES Operators. The
Company shall convene such a meeting periodically to discuss, and to consult
with affected LES Operators concerning, the technical and financial consequences
of each proposed change or




                                       39

<PAGE>

addition. A change or addition to the LES Technical Criteria and Operating
Procedures can be proposed by either the Company or the LESO. Prior to convening
a LES User Group Meeting, the Company shall, as soon as practicable, provide the
affected LES Operators with (a) notice of any proposed changes or additions to
the LES Technical Criteria and Operating Procedures, including any proposed
implementation schedule, and (b) sufficient information to enable the affected
LES Operators to evaluate the technical and financial consequences of the
proposed change or addition.

20.4 Subject to Clause 20.6, where a proposed change or addition to the LES
Technical Criteria and Operating Procedures would be mandatory thereby requiring
compliance by all LES Operators offering the affected Service, and would result
in either:

(a)     a typical implementation cost (as defined below) to be incurred by the
        affected LES Operators in excess of US$250,000; or

(b)     an aggregate of the typical implementation cost of the proposed change
        or addition and all other mandatory changes or additions to the LES
        Technical Criteria and Operating Procedures introduced in the
        immediately preceding twelve (12) months to be incurred by LES Operators
        in excess of US$500,000;

the Company shall not make the proposed change or addition without the consent
of a simple majority of those LES Operators attending and voting at the LES User
Group Meeting which offer the relevant Services affected by the proposed change
or addition or which intend to offer the relevant Services and have a
demonstrated financial commitment to do so. For the purposes of sub-paragraphs
(a) and (b), the "typical implementation cost" shall be the cost agreed between
both the Company and a simple majority of the LES Operators affected by the
proposed change or addition and who are present and voting at the Meeting. In
the absence of such agreement, the typical implementation cost shall be
determined by an expert in accordance with Clause 30.2.

20.5 Subject to Clause 20.6, where either:

(a)     the proposed change or addition to the LES Technical Criteria and
        Operating Procedures would involve a typical implementation cost less
        than or equal to the thresholds described in Clause 20.4; or

(b)     the proposed change or addition to the LES Technical Criteria and
        Operating Procedures would not be mandatory;

the Company may adopt the proposed change or addition, following the expiry of
twenty-one (21) days from the date on which notice of the proposed change or
addition has been



                                       40
<PAGE>


given, or as the case may be, following the LES User Group Meeting at which
such proposed change or addition was presented to the LES
Operators.

20.6 Notwithstanding any other provision of this Clause 20, the Company may
adopt any change or addition to the LES Technical Criteria and Operating
Procedures without prior consultation with the LESO where the Company reasonably
determines that an Urgent Operational Case has arisen. However, where any change
or addition to the LES Technical Criteria and Operating Procedures would, but
for the provisions of this Clause, have required a consent of the LES Operators
pursuant to Clause 20.4, a LES User Group Meeting shall be convened as soon as
possible at which the Company shall provide evidence of the Urgent Operational
Case and consider alterations to the change or addition.

20.7 The Company shall define a reasonable period applicable to all LES
Operators by which the LESO shall implement a mandatory change or addition to
the LES Technical Criteria and Operating Procedures, in consultation with those
LES Operators present at the Meeting, and shall formally notify all LES
Operators within ten (10) days after the Meeting. If the LESO does not comply
with the implementation period, Clause 8 shall apply.

21    SUSPENSION OF AUTHORIZATION

21.1 If the LESO fails to comply with any material term of this Agreement, then
the Company may give to the LESO written notice which shall specify the term or
terms of this Agreement in respect of which the LESO is not compliant. If the
LESO fails to cure the lack of compliance within a period of thirty (30) days
from the date of such notice (or such longer period as may be permitted by the
Company), the Company may suspend the Authorisation at any time thereafter upon
giving written notice to the LESO, except that such thirty (30) day period may
be shortened in the Urgent Operational Cases or as otherwise provided for in
this Agreement, particularly in Clauses 8 and 10.6.

21.2 The Company's right of suspension in this Clause 21 shall operate without
prejudice to the rights of the Company to suspend the Authorisation under other
express provisions of this Agreement or to terminate this Agreement in
accordance with Clause 22. Notwithstanding the foregoing, in the event that the
Company does not terminate the Agreement in whole or in part, or cannot do so
consistent with Clause 22, then the Company shall lift the suspension of the
Authorisation on the date on which the LESO resumes compliance with the terms of
this Agreement.

22    TERMINATION


                                       41



<PAGE>

Termination for Cause

22.1 Either Party (the "Terminating Party") may terminate the Agreement where
the other Party (The "Defaulting Party") is in default in the performance of any
material term under this Agreement and has failed to cure the default within
sixty (60) days from the date of written notice from the Terminating Party;
provided that if the Defaulting Party is the LESO and the cause of the default
is failure of payment of the Charges, then the applicable cure period shall be
reduced as provided for in Clause 10.6.


22.2 The Terminating Party may terminate the Agreement by written notice to the
Defaulting Party if:

(a)     an encumbrancer takes possession or a receiver is appointed over any of
        the property or assets of the Defaulting Party; or

(b)     the Defaulting Party makes any voluntary arrangement with its creditors
        or becomes subject to an administration order within the meaning of the
        bankruptcy laws of the United Kingdom or an equivalent order under the
        laws of the jurisdiction in which the LESO or Company (as the case may
        be) operates; or

(c)     the Defaulting Party goes into liquidation (except for the purposes of
        an amalgamation, reconstruction or other reorganization and in such
        manner that the entity resulting from the reorganization effectively
        agrees to be bound by or to assume the obligations imposed on the
        Defaulting Party under this Agreement); or

(d)     the Defaulting Party ceases, or threatens to cease, to carry on
        business.
Termination for Convenience

22.3 During the Initial Term, the LESO may terminate this Agreement for its
convenience upon at least twelve (12) months written notice to the Company.

23    CONSEQUENCES OF TERMINATION

Payment of Charges

23.1 Upon the termination or expiration of this Agreement for whatever reason,
any outstanding indebtedness of the Parties to one another shall become
immediately due and payable together with any interest due (calculated in
accordance with Clause 10.4) up until


                                       42

<PAGE>

the date of payment, provided that the Company shall refund the LESO the amount
of any Charges that the LESO has prepaid for any period of time after the date
of termination (provided that, in the event that the Agreement is terminated due
to the default of the LESO or at the LESO's convenience, then such amount shall
be subject to adjustments to recapture the pro rata amounts of any discount that
the LESO may have received by virtue of such prepayment).

23.2 The amounts payable by the LESO to the Company upon termination or
expiration of this Agreement shall include any Charges that would have been
payable in accordance with the terms of any traffic commitments (such as
take-or-pay commitments) mutually agreed by the Parties, subject to the relevant
provisions of this Agreement unless the Agreement is terminated due to a
material default by the Company, in which case, such traffic commitment-related
Charges that are in excess of the Services actually taken in accordance with
such commitment shall not be payable.

Other Consequences

23.3 Upon the termination or expiration of this Agreement for whatever reason,
the Company shall no longer be obligated to provide telecommunication services
via the Space Segment to the LESO and the LESO shall cease to provide Services
via the Space Segment through those of its LES(s) that are within the scope of
the termination. In addition:

(a)     The Trademark License Agreement and the IPR License Agreement shall
        immediately terminate in accordance with their terms.

(b)     The Parties shall each return to the other or, if requested by the
        Disclosing Party (as defined in Clause 17), destroy all Confidential
        Information belonging to the other Party. Any destruction of documents
        must be confirmed in writing to the Disclosing Party.

23.4 Upon termination of this Agreement, the LESO shall have the right to make
any transitional arrangements that it deems fit with respect to its customers,
unless otherwise mutually agreed by the Parties.

23.5 The rights set forth in this Clause 23 shall not prejudice any other right
or remedy of either Party, at law, subject to Clause 30.

24    ASSIGNMENTS AND SUBCONTRACTING


                                       43

<PAGE>



24.1 Subject to Clause 24.2, neither Party shall assign, transfer or charge all
or any of its rights and/or obligations under the Agreement without the prior
written consent of the other Party, and further provided that any such
assignment, transfer, or charge shall not relieve the assigning Party from
liability for the performance of any of its past, present or future obligations
(including financial obligations) or duties under the Agreement. Notwithstanding
the foregoing, the Company may assign its right to receive payment of the
Charges from the LESO hereunder subject to the provision of prior notice to the
LESO and the Company's agreement to hold the LESO harmless from any claims from
the assignee of such right or its Affiliates (other than claims related to
failure of payment by the LESO hereunder or claims against the LESO that are
unrelated to this Agreement).

24.2 The consent required for assignment under Clause 24.1 shall not be withheld
unreasonably where the assignment or charge is to an Affiliate of the assigning
Party or an entity that is the result of a merger or reorganization of the
assigning Party.

25    WAIVER

25.1 No delay in exercising or failing to exercise by either Party of any right
or remedy hereunder and no custom or practice of the Parties at variance with
the terms hereof shall constitute a waiver of any of the Parties' rights or
remedies hereunder.

25.2 No waiver by either Party of any particular default by the other Party
shall affect or impair either Party's rights in respect of any subsequent
default of any kind by the other Party, nor shall any delay or omission of
either Party to exercise any rights arising from any default affect or impair a
Party's rights in respect of the said default or any other default of the other
Party hereunder. Subsequent acceptance by the Company of any payments by the
LESO shall not be deemed a waiver of any preceding breach by the LESO of any of
the terms or conditions of this Agreement.

26    INVALIDITY

26.1 Should any provision of this Agreement be found to be invalid, illegal or
unenforceable under the laws of any relevant jurisdiction in any respect, the
invalid, illegal or unenforceable aspects of such provision shall be given no
effect and shall be deemed not to be included in this Agreement without
invalidating any of the remaining provisions of this Agreement. The Parties
shall forthwith enter into good faith negotiations to amend the Agreement in
such a way that, as amended, is valid, legal, enforceable, and, to the maximum
extent possible, reflects the intended effect of the invalid, illegal or
unenforceable provision.

                                       45




<PAGE>

29.2 The Parties intend that the relationship created between them by this
Agreement shall be as independent contractors. This Agreement is not to be
construed in any way as creating any partnership, principal-agent,
master-servant, joint venture or other similar relationship between the Parties.

30    SETTLEMENT OF DISPUTES

30.1 The Parties shall use all reasonable endeavours to resolve any dispute,
which shall include mediation where appropriate.

Disputes to be determined by an expert

30.2 With respect to any matter or dispute that is required by the express terms
of this Agreement to be resolved by an expert under this Clause, the matter or
dispute, on the application of either Party, shall be referred for resolution to
an independent firm of internationally recognised chartered accountants in
London that is agreeable to both Parties, or, failing agreement within thirty
(30) days from the date on which the matter or dispute arises, to be selected by
the President (for the time being) of the Institute of Chartered Accountants in
England and Wales. Once engaged, the firm shall act as an expert and not as an
arbitrator and shall be charged by the Parties to render its decision within
ninety (90) days of the date of submission of the matter or dispute in question
or within such shorter period as may be agreed by the Parties. Any determination
rendered by the expert shall be binding on the Parties, provided that either
Party may invoke the arbitration procedures under Clause 30.5 to review the
decision of the expert; provided further, however, that the appealing Party
shall bear all of the expenses of the arbitration and of the other Party (in
relation to its participation in the arbitration) (the amount of which is to be
determined by the arbitral tribunal) in the event that the arbitration affirms
the determination of the expert (notwithstanding the provisions of Clause 30.4).

30.3 The LESO and the Company undertake to give all necessary information and
assistance to the expert, including making all relevant accounting records
available on a timely basis in order to resolve the matter in dispute.

30.4 Except as provided in Clause 30.2 above, the Company and the LESO shall
each bear their own costs and expenses in connection with the resolution of the
dispute. The costs and expenses of the expert shall be paid in equal shares by
the Parties.

Disputes to be determined by arbitration

30.5 Subject to Clause 30.6, any dispute, controversy or claim arising out of or
relating to this Agreement, or the breach, termination or invalidity thereof,
shall be referred



                                       46


<PAGE>

to and finally resolved by arbitration in accordance with the Arbitration Rules
of the London Court of International Arbitration (LCIA) presently in force ("the
Rules"). The appointing authority shall be the LCIA. Unless otherwise agreed by
the Parties, the number of arbitrators shall be three (3) (of whom each Party
shall select one (1) and the third to be agreed by the other two (2)
arbitrators). The language of the arbitration shall be English and the place of
arbitration shall be London. Any arbitration award rendered in accordance with
this Clause shall be final and binding on the Parties. The Parties waive
irrevocably their right to any form of appeal, review or recourse to any state
court or other judicial authority, insofar as such waiver may be validly made.

30.6 For the avoidance of doubt, any dispute, controversy or claim which is
required by the terms of this Agreement to be resolved by an expert under Clause
30.2 may be referred to arbitration in accordance with Clause 30.5 only after
the expert has rendered his determination under Clause 30.2.

30.7 Notwithstanding Article 25.3 of the Rules, any Party may apply to any state
court or other judicial authority for interim or conservatory measures at any
stage prior to, or after, the commencement of an arbitration under Clause 30.5.

30.8  The LESO irrevocably:

(a) consents generally in accordance with the State Immunity Act 1978 to relief
being given against it in England or any other jurisdiction by way of injunction
or order for specific performance or for the recovery of any property whatsoever
or other provisional or protective measures and to its property being subject to
any process for the enforcement of a judgment or any process effected in the
course or as a result of any action in rem;

(b) waives and agrees not to claim any immunity from suits and proceedings
(including actions in rem) in England or any other jurisdiction and from all
forms of execution, enforcement or attachment to which it or its property is now
or may hereafter become entitled under the laws of any jurisdiction and declares

listed on a Relevant Exchange within approximately two (2) years from the
Effective Date (the IPO Period).

3.2 By a date that is no later than one hundred eighty (180) days following the

Shareholders of the Holdings Board's decision and entertaining any Shareholder

shall use all reasonable endeavors to prepare all necessary documentation,
convene and hold any necessary meetings of the Holdings Board or the
Shareholders and take such action as is necessary (or desirable) to ensure the
complete and punctual fulfillment of the IPO.

3.6 Holdings shall co-operate with relevant competition authorities in
monitoring progress towards increasing investment in Holdings by
non-Shareholders to appropriate levels.

3.7 Without prejudice to the rights of Shareholders to direct the Holdings Board
by special resolution pursuant to Article 138 of the New Holdings Articles in
relation to the timing, pricing and other significant conditions of the IPO, the
Shareholders hereby agree to ratify and confirm any decision of the Holdings
Board to proceed with an IPO in accordance with this clause 3 and agree not to
challenge any determination or decision relating thereto.

by special resolution pursuant to Article 138 of the New Holdings Articles in
relation to the timing, pricing and other significant conditions of the IPO and
the Shareholders' obligations contained in Clause 2, the Shareholders agree
that, in the event that the Holdings board resolves to undertake an IPO
(whether, or not within the IPO Period), the shareholders shall exercise all
voting rights and power, direct and indirect, available to them to support the
Holdings Board's decision and to ensure the complete and punctual fulfilment of
the IPO. This clause shall apply to all matters which require Shareholder
approval for the



                                       7

fulfilment of the IPO and includes, without limitation to the generality of the
foregoing, those matters described below:

    other requirements of a Relevant Exchange or any amendment suggested by the
    Holdings Board or required by sponsors/brokers to the IPO; and

(f) effecting the re-registration of Holdings as a public limited company.

4.2 The Shareholders agree that, if the Holdings Board decides to undertake an
IPO (whether or not within the IPO Period), the Shareholders shall take such
action, and execute such documents as may be reasonably recommended by the
Holdings Board or as required by the rules of any Relevant Exchange and are
reasonably necessary (or desirable) to give effect to the IPO in accordance with
any reasonable timetable adopted by the Holdings Board from time to time,
including being bound by any restrictions on sale in respect of their Holdings
Ordinary Shares for a transitional period following the IPO as shall be deemed
necessary or desirable by the Holdings Board or the investment bank appointed
pursuant to clause 3.2 or as required from time to time by any Relevant Exchange
or regulatory authority PROVIDED THAT no Shareholder shall be obliged without
its agreement (which it may give or withhold as it thinks fit in its absolute
discretion) to dispose of any of its Holdings Ordinary Shares.

DIRECTIONS TO TRUSTEE

5.  Each Beneficiary undertakes to procure that, for so long as that

TERMINATION OF TRUST DEED 1

6. If at any time any Beneficiary's Holdings Ordinary Shares cease to be
subject to the trust created by Trust Deed 1, with effect from such time the

defined in this Agreement.

AMENDMENTS TO SCHEDULES

7.  Each of the signatories and the Beneficiaries hereby appoint Holdings as its
agent for the purpose of updating or supplementing the Schedules to this
Agreement.

THIRD PARTY PURCHASER

8.1 If any Shareholder (or, as the case may be, a Beneficiary through a Trustee)
transfers any of its Holdings Ordinary Shares to a third Party (in accordance
with the New Holdings Articles) (a Transferor), it shall procure that such third
party shall first have entered into a deed poll in the form or substantially the
form set out in Schedule 6 and into such agreement(s) with the other Parties to
this Agreement as may be necessary to ensure that such third Party is bound by
provisions corresponding to provisions of this Agreement, whether by executing a
deed poll in relation to the Agreement or otherwise. The continuing Parties
hereby agree to release and discharge the Transferor (save in relation to any
antecedent breach) from all its obligations under this Agreement provided the
relevant third party enters into a deed poll as required by this Clause.

8.2 Holdings shall refuse to register the transfer of any Holdings Ordinary
Shares by any Shareholder (or, as the case may be, a Beneficiary through a
Trustee) to a third Party in the event that such transfer occurs other than in a

transferring Shareholder complies with the requirements of Clause 8.1 hereunder


                                       9

refusal.
