SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

         In connection with the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995 (the "Reform Act"), we are hereby providing
cautionary statements identifying important factors that could cause our actual
results to differ materially from those projected in forward-looking statements
(as such term is defined in the Reform Act) made in this Current Report on Form
8-K. Any statements that express, or involve discussions as to, expectations,
beliefs, plans, objectives, assumptions or future events or performance (often,
but not always, through the use of words or phrases such as "will likely
result," "are expected to," "will continue," "is anticipated," "estimated,"
"intends," "plans," "projection" and "outlook") are not historical facts and may
be forward-looking. Such statements involve estimates, assumptions and
uncertainties that could cause actual results to differ materially from those
expressed in the forward-looking statements. Accordingly, any such statements
are qualified in their entirety by reference to the factors discussed in our
Annual Report on Form 10-K for the year ended December 31, 1998, and investors
should not place undue reliance on any such forward-looking statements. Among
the significant factors that have a direct bearing on our results of operations
are the potential risk of delay in implementing our business plan; increased
costs of construction and launch of necessary satellites; our dependence on
Space Systems/Loral, Inc. to construct and arrange the launch of our satellites;
risk of launch failure; unproven market and unproven applications of technology;
our dependence on Lucent Technologies, Inc.; unavailability of receivers and
antennas; and our need for additional financing.

         Management cannot assess the impact of each such factor on our business
or the extent to which any factor, or combination of factors, may cause actual
results to differ materially from those contained in any forward-looking
statements. Further, any forward-looking statement speaks only as of the date on
which such statement is made, and we undertake no obligation to update any
forward-looking statement or statements to reflect events or circumstances after
the date on which such statement is made or to reflect the occurrence of
unanticipated events. New factors emerge from time to time, and it is not
possible for management to predict all of such factors.

ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT

         On April 6, 1999, we dismissed our independent auditors,
PricewaterhouseCoopers LLP ("PricewaterhouseCoopers"). The decision to change
accountants was approved by the Audit Committee of our Board of Directors.

         During the fiscal years ended December 31, 1997 and December 31, 1998
and the period from January 1, 1999 through April 6, 1999, there were no
disagreements with PricewaterhouseCoopers on any matter of accounting principles
or practices, financial statement disclosure, or auditing scope or procedure,
which disagreements, if not resolved to the satisfaction of
PricewaterhouseCoopers, would have caused them to make a reference to the
subject matter of such disagreements in connection with their reports.


         PricewaterhouseCoopers' report on our financial statements for the
fiscal year ended December 31, 1998 was modified to include an explanatory
paragraph as to our ability to continue as a going concern through December 31,
1999. This modification was due to the fact that we did not have the financial
resources to meet our capital expenditure obligations through December 31, 1999.
We expect to continue to finance our capital expenditures through the sale of
debt or equity securities or a combination thereof. Otherwise,
PricewaterhouseCoopers' reports on our financial statements for the fiscal year
ended December 31, 1997 and December 31, 1998 did not contain an adverse opinion
or disclaimer of opinion, and were not qualified or modified as to uncertainty,
audit scope or accounting principle.

         On October 7, 1998, PricewaterhouseCoopers' reissued report on our
financial statements for the fiscal year ended December 31, 1997 was modified to
include an emphasis of a matter paragraph as to our ability to continue as a
going concern through 1999. However, in view of the funds we raised through
equity financings in the fourth quarter of 1998, PricewaterhouseCoopers
subsequently revised their reissued report, which was included in a Current
Report on Form 8-K, to remove the paragraph concerning this uncertainty.

         On April 6, 1999, we engaged Arthur Andersen LLP ("Arthur Andersen") as
our independent auditors who will audit and report on our financial statements
for the fiscal year ended December 31, 1999.

         Prior to engaging Arthur Andersen, neither we nor anyone acting on our
behalf consulted with Arthur Andersen regarding the application of accounting
principles to any specified transaction or the type of audit opinion that might
be rendered on our financial statements, and neither a written report nor oral
advice was provided to us that Arthur Andersen concluded was an important factor
considered by us in reaching a decision as to the accounting, auditing or
financial reporting issue. In addition, prior to engaging Arthur Andersen,
neither we nor anyone acting on our behalf consulted with Arthur Andersen with
respect to any matter that was either the subject of a disagreement (as defined
in Item 304(a)(1)(iv) of Regulation S-K) or a reportable event (as described in
Item 304(a)(1)(v) of Regulation S-K).

         We requested that PricewaterhouseCoopers furnish us with a letter
addressed to the Securities and Exchange Commission stating whether it agrees
with the above statements. A copy of that letter dated April 9, 1999 is filed as
exhibit 16 to this Current Report on Form 8-K.
