                                    SUMMARY

     This summary highlights information contained elsewhere in this prospectus.
Because it is a summary, it does not contain all of the information that you
should consider before you participate in this exchange offer. You should read
this entire prospectus carefully, including the 'Risk Factors' section. The term
'initial notes' refers to the 14 1/2% Senior Secured Notes due 2009 that were
issued on May 18, 1999. The term 'exchange notes' refers to the 14 1/2% Senior
Secured Notes due 2009 offered by this prospectus. The term 'notes' refers to
the initial notes and the exchange notes, collectively.

                               ABOUT OUR BUSINESS

     We are building a digital quality radio service that will broadcast up to
100 channels directly from satellites to vehicles. CD Radio will be broadcast
throughout the continental United States, over a frequency band, the 'S-band,'
that will augment traditional AM and FM radio bands. We hold one of only two
licenses issued by the Federal Communications Commission (the 'FCC') to build,
launch and operate a national satellite radio broadcast system. Under our FCC
license, we have the exclusive use of a 12.5 megahertz ('MHz') portion of the
S-band for this purpose. Our service, which will be primarily for motorists,
will offer 50 channels of commercial-free, digital quality music programming and
up to 50 channels of news, sports, talk and entertainment programming. We
currently expect to commence CD Radio broadcasts at the end of the fourth
quarter of 2000, at an anticipated subscription price of $9.95 per month.

     As an entertainment company, we intend to design and originate programming
on each of our 50 commercial-free music channels. Each channel will be operated
as a separate radio station with a distinct format. These formats will include a
variety of classical, popular, rock, jazz, soul, contemporary, Latin, country,
alternative and children's music. The actual formats will be determined before
the launch of the service and may be varied from time to time to optimize
customer satisfaction. Some of the music channels will offer continuous music
while others will have program hosts, depending on the type of music
programming.

     Programming on our non-music channels will be provided by third parties,
and to date we have entered into programming agreements with content providers
for 25 of these channels, including NPR, BBC, Bloomberg News Radio, C-SPAN and
Sports Byline USA. A majority of our non-music channels will contain
advertising, which will augment our subscription revenue. These channels will
include news and talk shows and special interest programming directed to a
diverse range of groups, including sports and outdoor enthusiasts, Hispanic
listeners and truck drivers.

     On June 11, 1999, we entered into an agreement with FORD MOTOR COMPANY
which anticipates Ford manufacturing, marketing and selling vehicles that
include receivers capable of receiving CD Radio's broadcasts. We expect that the
first such vehicles will be available at the end of fourth quarter of 2000. This
exclusive agreement includes all seven Ford brands -- Ford, Lincoln, Mercury,
Mazda, Jaguar, Aston Martin and Volvo. In connection with this agreement, we
issued to Ford warrants that will enable Ford to purchase up to four million
shares of our common stock. Ford may exercise its warrants based on the number
of CD Radio receivers it installs in vehicles and may exercise all of its
warrants once it has installed CD Radio receivers in four million vehicles.

     We have also established relationships with major industry suppliers to
design and/or develop the most important elements of our system:

     SPACE SYSTEMS/LORAL, INC. is constructing and will launch and deliver our
satellites in-orbit and checked-out. Loral is a leading full-service provider of
commercial satellite systems and services. Loral has scheduled the launch of our
satellites for January, March and May of 2000 on Proton launch vehicles.

     LUCENT TECHNOLOGIES, INC. has completed the design for the overall
architecture of the CD Radio system and is developing and will manufacture a
custom designed chip set for use in CD Radio receivers.

     DELCO ELECTRONICS CORPORATION is designing and developing and has agreed to
manufacture three-band receivers (AM/FM/CD Radio) and satellite antennas for
sale to major automotive manufacturers. Delco is the world's largest producer of
audio systems for original automotive equipment manufacturers and is a leader in
mobile communications technology. Delco has agreed to complete the design and
development work and have three-band receivers and antennas available for sale
to automobile manufacturers by March 2001.

     ALPINE ELECTRONICS INC. is designing and developing FM modulated receivers
(which enable FM radios to receive CD Radio broadcasts) and three-band receivers
for installation by automotive manufacturers and sale to consumers in the
electronics aftermarket. Alpine, a leading manufacturer of high performance
mobile electronics, has specialized in car audio products for over 30 years and
has provided original high-end audio systems directly to many automotive
manufacturers, including Ford, Honda, Acura and BMW.

     A subsidiary of Matsushita, the world's largest consumer electronics
company and the maker of PANASONIC products, is designing and developing
three-band receivers for installation by automotive manufacturers and for sale
to consumers in the electronics aftermarket.

     RECOTON CORPORATION is designing and developing FM modulated receivers,
radio cards (wireless adapters for cassette players) and hard-wired and wireless
satellite antennas. Recoton, the owner of the Jensen, Advent, AR/Acoustic
Research and InterAct brands, is the third largest producer of aftermarket car
stereos sold in the United States and has one of the largest distribution
systems for automotive consumer electronics, with over 30,000 points of
presence.

                          THE CD RADIO DELIVERY SYSTEM

     The CD Radio delivery system will consist of three principal components:

     THE SATELLITES. To provide CD Radio, we have contracted with Loral to build
four satellites, to arrange for launch service providers to launch three of
these satellites and to deliver the three launched satellites, in-orbit, by June
30, 2000. We intend to hold the fourth satellite as a ground spare.

     Our satellites will incorporate a design which will act as a 'bent pipe,'
relaying signals received from uplink transmittals directly to vehicles on the
ground. Our satellites will not contain on-board processors. All of our
processing operations will be on the ground where they will be accessible for
maintenance and continuing technological upgrade without the need to launch
replacement satellites.

     In May 1998, we announced our plan to change the orbital location of our
satellites from geostationary orbits over the equator to inclined elliptical
orbits. This modification will allow our satellites to maximize the time spent
over the continental United States, which will permit us to fully utilize the
bandwidth allocated to us by the FCC. This modification must be approved by the
FCC, which we have requested.

     THE NATIONAL BROADCAST STUDIO. We will originate up to 100 channels of
programming from our National Broadcast Studio in Rockefeller Center in New York
City. The National Broadcast Studio will house our music library, facilities for
programming origination, programming personnel and program hosts, and facilities
to transmit programming to our orbiting satellites, to activate or deactivate
service to subscribers and to perform the tracking, telemetry and control of our
satellites.

     THE RECEIVERS. We expect consumers will receive CD Radio either by
purchasing specially designed radio receivers for their existing vehicles or
through a new generation of three-band radios which will come fully installed in
new vehicles by automobile manufacturers.

     In the automotive aftermarket, we expect that CD Radio subscribers will
have the choice of one of three different receiving devices for their cars -- an
FM modulated receiver, a three-band receiver and a radio card.

                                       4

      FM Modulated Receivers. The CD Radio FM modulated receiver will be usable
      in all vehicles that have an FM radio, which represent approximately 95%
      of all U.S. vehicles. Each FM modulated receiver will operate with a
      device that will be approximately the size of a 35mm camera and that will
      be mounted either in the vehicle's trunk, behind the dashboard, in the
      glove compartment or under a seat. We expect the retail price of this FM
      modulated receiver, with a hard-wired satellite antenna and professional
      installation, will be approximately $299.

      Three-Band Receivers. We expect that consumers who wish to replace their
      vehicle's sound system will be able to purchase receivers capable of
      receiving AM, FM and CD Radio broadcasts. We expect the retail price of
      these CD Radio-ready receivers, including the antenna and professional
      installation, will be approximately $150 more than similar receivers which
      are not capable of receiving CD Radio broadcasts.

      Radio Cards. CD Radio's wireless adapter, or radio card, will not require
      professional installation and will be usable by all vehicles in the United
      States equipped with a cassette player, which represent approximately 65%
      of all vehicles on the road. We expect the retail price of the radio card,
      including the wireless satellite antenna, will be approximately $199.

     All CD Radio receivers will have a visual display that will indicate the
channel and format selected, as well as the title, recording artist and album
title of the musical selection being played.

     Each of the elements of the CD Radio system -- satellites, terrestrial
repeater network, National Broadcast Studio and CD Radio receivers -- is on
schedule to permit us to begin operations at the end of the fourth quarter of
2000.

     We believe there will be significant consumer demand for CD Radio. Market
research conducted for us by The Yankee Group, Inc. shows that radio listeners
today are substantially dissatisfied with both AM and FM radio because of
frequent commercial interruptions, lack of variety in programming and loss of
signal strength. CD Radio's commercial-free music, wide variety of formats and
nearly seamless national coverage have been designed to address these key
disadvantages of existing commercial radio.

                               SUMMARY OF TERMS OF THE EXCHANGE NOTES

Issuer....................................  CD Radio Inc.

Notes Offered.............................  $200 million aggregate principal amount of 14 1/2%
                                            Senior Secured Notes due 2009. The form and terms of the
                                            exchange notes are the same as the form and terms of the
                                            initial notes except that the exchange notes are
                                            registered under the Securities Act, will not bear
                                            legends restricting their transfer and will not be
                                            entitled to registration rights under our notes
                                            registration rights agreement. The exchange notes will
                                            evidence the same debt as the initial notes and both the
                                            initial notes and the exchange notes will be governed by
                                            the same indenture.

Maturity..................................  May 15, 2009.

Interest Payment Dates....................  We will pay interest on the exchange notes on May 15 and
                                            November 15 of each year, commencing November 15, 1999.
                                            We used approximately $79.3 million of the proceeds of
                                            the offering of units consisting of initial notes and
                                            warrants to purchase common stock to purchase a
                                            portfolio of U.S. government securities in an amount
                                            sufficient to pay the first six payments of interest on
                                            the notes.

Ranking...................................  The exchange notes will be senior secured obligations
                                            and will rank senior in right of payment to all existing
                                            and future subordinated indebtedness and will rank
                                            equally with all existing and future senior
                                            indebtedness, including our 15% Senior Secured Discount
                                            Notes due 2007 (the 'Senior Discount Notes'). The
                                            indenture permits some kinds of subsidiary indebtedness
                                            and permits us to secure some kinds of indebtedness,
                                            which will rank equally with the exchange notes and the
                                            Senior Discount Notes. Please refer to the section of
                                            this prospectus entitled 'Description of the
                                            Notes -- Certain Covenants -- Limitation on
                                            Indebtedness.' As of June 30, 1999, we had $480 million
                                            in aggregate principal amount of indebtedness
                                            outstanding (including the notes) which ranked equal in
                                            right of payment with the exchange notes, all of which
                                            was secured. As of September 30, 1998, our subsidiaries
                                            had no liabilities outstanding.

Security..................................  The exchange notes will be secured by a first priority
                                            perfected security interest in all of the issued and
                                            outstanding common stock of our subsidiary, Satellite CD
                                            Radio, Inc. (the 'Pledged Stock'). The security interest
                                            benefitting the exchange notes will rank equally with
                                            the security interest benefitting our Senior Discount
                                            Notes, which are also secured by a first priority
                                            perfected security interest in the Pledged Stock.

                                            license. In addition, we used approximately $79.3
                                            million of the proceeds from the offering of the units
                                            consisting of initial notes and warrants to purchase a
                                            portfolio of U.S. government securities in an amount
                                            sufficient to pay the first six payments of interest on
                                            the notes. We pledged this portfolio of securities for
                                            the benefit of the holders of the initial notes and the
                                            exchange notes. See 'Description of the
                                            Notes -- Security.' Under the indenture, we and our
                                            subsidiaries are entitled to incur, subject to
                                            significant conditions and limitations, additional
                                            indebtedness. This additional indebtedness could also be
                                            secured by the issued and outstanding stock of Satellite
                                            CD Radio, Inc. Please refer to the section of this

                                            United States federal income tax purposes. The original

Absence of a Public Market for the

                                  RISK FACTORS

     In addition to the other information in this prospectus, the following
factors should be considered carefully in evaluating us and our business. This
prospectus contains some forward-looking statements. Actual results and the
timing of some events could differ materially from those projected in the
forward looking statements due to a number of factors, including those described
below and elsewhere in this prospectus. See 'Managment's Discussion and Analysis
of Financial Condition and Results of Operations -- Special Note Regarding
Forward Looking Statements.'

OUR BUSINESS IS STILL IN THE DEVELOPMENT STAGE

     Historically, we have generated only losses. We are a development stage
company. The service we propose to offer, CD Radio, is in a relatively early
stage of development and we have never recognized any operating revenues or
conducted any operations. Since our inception, we have concentrated on raising
capital, obtaining required licenses, developing technology, strategic planning,
market research and building our infrastructure. Our financial results from our
inception on May 17, 1990 through June 30, 1999, are as follows:

      no revenues;

      net losses of approximately $95 million (including net losses of
      approximately $5 million during the year ended December 31, 1997 and $48
      million during the year ended December 31, 1998); and

      net losses applicable to common stock of approximately $206 million, which
      includes a deemed dividend on our former 5% Delayed Convertible Preferred
      Stock (the '5% Preferred Stock') of $52 million. In November 1997, we
      exchanged 1,846,799 shares of our 10 1/2% Series C Convertible Preferred
      Stock for all of the issued and outstanding shares of 5% Preferred Stock.

     We do not expect any revenues before 2001, and still have a variety of
hurdles to surmount before commencing operations. We have not started to
broadcast CD Radio and do not expect to generate any revenues from operations
until the first quarter of 2001 or to generate positive cash flow from
operations until the third quarter of 2001, at the earliest. Our ability to
generate revenues, generate positive cash flow and achieve profitability will
depend upon a number of factors, including:

      raising additional financing;

      the timely receipt of all necessary regulatory authorizations;

      the successful and timely construction and deployment of our satellite
      system;

      the development and manufacture by one or more consumer electronics
      manufacturers of devices capable of receiving CD Radio; and

      the successful marketing and consumer acceptance of CD Radio.

We cannot assure you that we will accomplish any of the above, that CD Radio
will ever commence operations, that we will attain any particular level of
revenues, that we will generate positive cash flow or that we will achieve
profitability.

WE NEED ADDITIONAL FINANCING TO BUILD AND LAUNCH OUR SERVICE

     We need more money to continue implementing our business plan. We require
near-term funding to continue building our system. We believe we can fund our
planned operations and the construction of our satellite and terrestrial system
into the second quarter of 2000 from our working capital at October 14, 1999,
which includes the proceeds from:

      our sale of 5,000,000 shares of common stock to Prime 66 Partners, L.P.
      for $100 million on November 2, 1998;

                                       12



<PAGE>

      our sale of shares of 9.2% Series A Junior Cumulative Convertible
      Preferred Stock to Apollo Investment Fund IV, L.P. and Apollo Overseas
      Partners IV, L.P., which we refer to as the 'Apollo Investors,' for $135
      million on December 23, 1998;

      our sale of 200,000 units, each unit consisting of $1,000 principal amount
      of 14 1/2% senior secured notes due 2009 and three warrants, each to
      purchase 3.792 shares of our common stock, for $200 million on May 18,
      1999;

      our sale of 3,450,000 shares of common stock in a public offering on
      September 29, 1999 and October 6, 1999;

      our sale of $143.75 million aggregate principal amount of our 8 3/4%
      convertible subordinated notes due 2009 in a public offering on
      September 29, 1999 and October 6, 1999; and

      our sale of shares of 9.2% Series B Junior Cumulative Convertible
      Preferred Stock to the Apollo Investors for $65 million on October 13,
      1999.

     We refer to our 9.2% Series A Junior Cumulative Convertible Preferred Stock
and our 9.2% Series B Junior Cumulative Convertible Preferred Stock together as
the 'Junior Preferred Stock.'

     Although we believe that we have raised sufficient funds to complete the
construction of our proposed system, we currently do not have sufficient
financing commitments to completely fund our first full year of operations. We
expect to satisfy the remainder of our funding requirements through additional
bank borrowings, the issuance of debt or equity securities or a combination of
these sources. We cannot assure you that we will obtain additional financing on
favorable terms or that we will do so on a timely basis.

     We estimate that we will need the following amounts for the following
purposes:

<TABLE>
<S>                                                           <C>
  to develop and commence operation of CD Radio by the end of   $1,170 million
  the fourth quarter of 2000

  to fund operations through the first full year of operations  $  150 million
  ending with the fourth quarter of 2001

  Total through the first year of operations                    $1,320 million
</TABLE>

     We have or expect that we may have use of the following funds to develop
and operate CD Radio:

<TABLE>
<S>                                                           <C>
  net funds raised through October 14, 1999 (including those    $1,110 million
  borrowed under a term loan facility which must be
  refinanced or repaid in an aggregate principal amount of
  $115 million by the earlier of February 29, 2000 and ten
  days prior to the launch of our second satellite)

  funds which Bank of America may, but is not required to,      $  106 million
  arrange for us ($225 million less $115 million to repay
  our existing bank credit facility, net of estimated fees and
  expenses)

  Total funds we have raised and additional funds we expect   $1,216 million
  to be able to access
</TABLE>

     After we give effect to the funds we have and the additional funds we have
identified, we estimate that we will need an additional $104 million to fund our
business through the first full year of operations. If Bank of America is unable
to arrange a new credit facility, we will need to raise $115 million to
refinance our existing credit facility in the first quarter of 2000 and an
additional $106 million to fund our operations through the end of the fourth
quarter of 2000. The availability of this new credit facility, which we expect
to draw on to repay amounts outstanding at maturity under our existing bank
credit facility, will be influenced by a variety of factors, some of which,
including the market for syndicated bank loans generally, are outside of our
control. We will require more money than estimated if there are delays, cost
overruns, launch failures or other adverse developments.

                                       13



<PAGE>

WE FACE MANY FINANCING CHALLENGES AND CONSTRAINTS

     We face many challenges and constraints in financing our development and
operations, including those listed below.

     Our debt instruments limit our ability to incur indebtedness. The
indentures governing our 15% senior secured discount notes due 2007 and our
14 1/2% senior secured notes due 2009 limit our ability to incur additional
indebtedness. In addition, we expect any future senior indebtedness will contain
similar limits on our ability to incur additional indebtedness.

     We will have to satisfy a variety of conditions before we can obtain any
syndicated bank borrowings. We entered into a credit agreement with Bank of
America and other lenders in July 1998 under which Bank of America and the other
lenders agreed to provide us a term loan facility of up to $115 million maturing
on the earlier of February 29, 2000 and ten days prior to the launch of our
second satellite. Bank of America has also agreed to attempt to arrange a
syndicate of lenders to provide us with a term loan facility of $225 million. To
borrow the funds under this term loan facility, we must first satisfy specified
conditions and negotiate, execute and deliver definitive loan documents. The
availability of this new credit facility will be influenced by a variety of
factors, some of which, including the market for syndicated bank loans
generally, are outside of our control. We intend to use a portion of the
proceeds from this term loan facility to repay amounts outstanding at maturity
under our existing term loan facility and for other general corporate purposes.
The term loan facility would provide us with approximately $106 million of net
additional funds after repayment of the existing term loan facility and the
payment of fees and expenses.

     We have substantial near-term requirements for additional funds. We require
substantial funds to construct and launch the satellites that will be part of
our broadcast system. We are committed to make aggregate payments of
approximately $736 million under our Amended and Restated Contract with Loral
(the 'Loral Satellite Contract'), which includes $15 million of long-lead time
elements for a fifth satellite and $3 million for integration analysis of the
viability of using the Sea Launch platform as an alternative launch vehicle for
our satellites. We started paying for the construction of the satellites in
April 1997 and we must pay further installments through December 2003. Loral has
agreed to defer a total of $50 million of the payments under the Loral Satellite
Contract originally scheduled for payment in 1999. Interest on the deferred
amounts accrues at 10% per annum until December 2001, at which time interest
becomes payable quarterly in cash. We must pay the amounts deferred in
installments beginning in June 2002.

     If we fail to secure the financing required to pay Loral on a timely basis,
we risk:

      delays in launching our satellites and starting broadcasting operations;

      increases in the cost of building or launching our satellites or other
      activities necessary to put CD Radio into operation;

      a default on our commitments to Loral, our creditors or others;

      our inability to commence CD Radio service; and

      the forced discontinuance of our operations or the sale of our business.

     A delay in introducing our service could hinder our ability to raise
additional financing. Any delay in implementing our business plan would hurt our
ability to obtain the financing we need by adversely affecting our expected
results of operations and increasing our cost of capital. Our ability to begin
offering our CD Radio service at the end of the fourth quarter of 2000 depends
on Loral delivering completed satellites before the launch dates and providing
or obtaining launch services on a timely basis. A significant delay in the
development, construction, launch or commencement of operation of our satellites
would adversely affect our results of operations in a material way.

     Other delays in implementing our business plan could also materially
adversely affect our results of operations. Several factors could delay us,
including the following:

      obtaining additional authorizations from the FCC;

      coordinating the use of S-band radio frequency spectrum with Mexico;

                                       14



<PAGE>

      delays in or modifications to the design, development, technical
      specifications, construction or testing of our satellites, receivers or
      other aspects of our system;

      delay in commercial availability of devices capable of receiving
      CD Radio;

      failure of our vendors to perform as anticipated; and

      a delayed or unsuccessful satellite launch or deployment.

We have previously incurred some delays in implementing our business plan.
During any period of delay, we would continue to need significant amounts of
cash to fund capital expenditures, administrative and overhead costs,
contractual obligations and debt service. Accordingly, any delay could
materially increase the aggregate amount of funds we need to commence
operations. Additional financing may not be available on favorable terms or at
all during periods of delay.

WE ARE DEPENDENT UPON LORAL TO BUILD AND LAUNCH OUR SATELLITES

     Our business depends upon Loral successfully constructing and launching the
satellites to transmit CD Radio. We are relying upon Loral to construct and to
deliver these satellites in orbit on a timely basis. We cannot assure you that
Loral will deliver the satellites or provide these launch services on a timely
basis, if at all. If Loral fails to deliver functioning satellites in a timely
manner, our business could be materially adversely affected. Although our
agreement with Loral requires Loral to pay us penalties for late delivery, based
on the length of the delay, these remedies may not adequately mitigate the
damage any launch delays cause to our business. In addition, if Loral fails to
deliver the designated launch services due to causes beyond its control, Loral
will not be liable for the delay or the damages caused by the delay. While the
satellites are under construction, Loral is at risk should anything happen to
the satellites. In addition, Loral is responsible for making sure the satellites
meet specific performance specifications at the time of launch (in the case of
our first three satellites) or at the time of delivery to our ground storage
location (in the case of our fourth satellite). However, if any satellite is
destroyed during or after launch or if the fourth satellite is damaged or
destroyed while in storage, Loral will not be responsible to us for the cost of
replacing it.

     We depend on Loral to obtain access to available slots on launch vehicles
and to contract with third-party launch service providers for the launch of our
satellites. A launch service provider may postpone one or more of our launches
for a variety of reasons, including:

      technical problems;

      a launch of a scientific satellite whose mission may be degraded by delay;

      the need to conduct a replacement launch for another customer; or

      a launch of another customer's satellite whose launch was postponed.

Generally, Loral is not liable to us for a satellite or launch failure. However,
if the first Proton launch vehicle used to launch our satellites fails, Loral
will provide us with a free replacement launch. The timing of this replacement
launch cannot be predicted, but in any event would not be before delivery of the
fourth satellite.

     We also depend on Loral to ensure that the software to test the satellites
before launch, to run the satellites and to track and control the satellites,
will be capable of handling the potential problems that may arise beginning on
January 1, 2000. These potential problems are known as 'The Year 2000 Issue.'
The Year 2000 Issue is the result of computer programs being written using two
digits (rather than four) to define a year, which could result in
miscalculations or system failures resulting from recognition of a date
occurring after December 31, 1999 as falling in the year 1900 (or another year
in the 1900s) rather than the year 2000 or thereafter. While currently the above
mentioned systems are not fully prepared to handle The Year 2000 Issue, Loral is
aware of this condition and has assured us that all Loral systems will be year
2000 compliant before the critical date of January 1, 2000.

WE ARE DEPENDENT ON LUCENT TO DESIGN AND DEVELOP CHIP SETS

     Our business depends upon Lucent successfully designing, developing and
manufacturing commercial quantities of integrated circuits (or chip sets), which
will be used in consumer electronic devices capable of receiving CD Radio's
broadcasts. If Lucent fails to deliver commercial quantities of the chip sets in
a timely manner, the costs of the chip set development work increases
significantly or the price of the chip set is not low enough to support the
introduction of consumer devices capable of receiving CD Radio, our business
will be materially adversely affected. We have agreed to pay Lucent the cost of
the development work related to the chip sets, currently estimated to be
approximately $27 million.

     We cannot assure you that:

      Lucent will be able to deliver significant quantities of chip sets in
      order for us to commence operations at the end of the fourth quarter of
      2000;

      the cost to us of the chip set development work will not exceed $27
      million; or

      Lucent will be able to establish a price for the chip sets which will be
      low enough to encourage and support the widespread introduction of
      consumer devices capable of receiving CD Radio.

WE ARE NOT SURE THERE WILL BE A MARKET FOR CD RADIO

     Currently no one offers a commercial satellite radio service such as
CD Radio in the United States. As a result, our proposed market is new and
untested and we cannot reliably estimate the potential demand for this service
or the degree to which our proposed service will meet that demand. We cannot
assure you that there will be sufficient demand for CD Radio to enable us to
achieve significant revenues or cash flow or profitable operations. CD Radio
will achieve or fail to gain market acceptance depending upon factors beyond our
control, including:

      the willingness of consumers to pay subscription fees to obtain satellite
      radio broadcasts;

      the cost, availability and consumer acceptance of devices capable of
      receiving CD Radio;

      our marketing and pricing strategies and those of our competitor;

      the development of alternative technologies or services; and

      general economic conditions.

OUR PLANNED SYSTEM RELIES ON UNPROVEN APPLICATIONS OF TECHNOLOGY

     Our satellite system applies technology in new and unproven ways. CD Radio
is designed to be broadcast from three satellites orbiting the Earth. Two of the
three satellites will transmit the same signal at any given time to receivers
that will receive signals through antennas. This design applies technology in
new and unproven ways. Accordingly, we cannot assure you that the CD Radio
system will work as planned.

     Some obstructions will adversely affect CD Radio reception. High
concentrations of tall buildings, other obstructions, such as those found in
large urban areas, and tunnels will block the signals from both transmitting
satellites. We plan to install terrestrial repeating transmitters to rebroadcast
CD Radio in some urban areas to mitigate this problem. However, some areas with
impediments to satellite line-of-sight may still experience 'dead zones.' We
cannot assure you that the CD Radio system will operate as planned with the
technology we have developed.

     Our system has never been tested with orbiting satellites. We cannot assure
you that the CD Radio system will function as intended until we test it with
orbiting satellites and antennas and receivers suitable for commercial
production. We have never done this kind of test because there are no commercial
satellites in orbit capable of transmitting radio signals on S-band frequencies
to the United States. In support of our application for our FCC license, we
conducted a terrestrial simulation of our proposed radio service from November
1993 through November 1994. For the demonstration, we transmitted S-band signals
to a prototype receiver and satellite dish antenna installed in a car to
simulate specific transmission characteristics of our planned system. As part of

                                       16



<PAGE>

the demonstration, the prototype receiver received 30 channels of compact disc
quality music while the car was driven throughout the range. We have also
successfully tested our system in San Francisco, where our terrestrial repeater
network has been completed.

SATELLITE LAUNCHES HAVE SIGNIFICANT RISKS

     We cannot assure you that the launches of our satellites will be
successful. Satellite launches have significant risks, including launch failure,
damage or destruction of the satellite during launch and failure to achieve a
proper orbit or operate as planned. The Loral Satellite Contract does not
protect us against the risks inherent in satellite launches or in-orbit
operations. Our three satellites are scheduled to be launched on Proton launch
vehicles, which are built by Russian entities. The Proton family of launch
vehicles has a launch success rate of 92% based on its last 50 launches. Past
experience, however, is not necessarily indicative of future performance.

     On July 5, 1999, the second stage of a Proton rocket launched from the
Baikonur Cosmodrome in Kazakhstan malfunctioned during flight. As a result of
this failure, Proton rocket launches were suspended and the Russian government
appointed an official investigatory commission. In late July 1999, the
commission announced that the failure was caused by a fire which started in one
of the launch vehicle's engines. Proton launches were successfully resumed in
September 1999. We cannot assure you that these developments will not delay one
or more of our anticipated satellite launches.

     As part of our risk management program, we contracted with Loral for the
construction of a fourth satellite that we will use as a ground spare and for
some of the long-lead time parts for a fifth satellite. We also plan to obtain
insurance covering a replacement launch to the extent required to cover risks
Loral does not assume.

SATELLITES HAVE A LIMITED LIFE AND MAY FAIL IN ORBIT

     We expect that our satellites will last approximately 15 years, and that
after this period their performance in delivering CD Radio will deteriorate. We
cannot assure you, however, of the useful life of any particular satellite. Our
operating results would be adversely affected if the useful life of our initial
satellites is significantly shorter than 15 years.

     The useful lives of our satellites will vary and will depend on a number of
factors, including:

      quality of construction;

      amount of fuel on board;

      durability of component parts;

      expected gradual environmental degradation of solar panels;

      random failure of satellite components, which could result in damage to or
      loss of a satellite; and

      in rare cases, damage or destruction by electrostatic storms or collisions
      with other objects in space.

If one of our satellites fails on launch or in orbit and if we are required to
launch our spare satellite, our operational timetable will be delayed for up to
six months. If two or more of our satellites fail on launch or in orbit, our
operational timetable could be delayed by at least 16 months.

INSURANCE MAY NOT COVER ALL RISKS OF LAUNCHING AND OPERATING SATELLITES

     There are many potential risks to insure. Our agreement with Loral does not
protect us against launch vehicle failure, failure of a satellite to deploy
correctly or failure of a satellite to operate as planned. Accordingly, we must
purchase insurance to protect adequately against these risks. We cannot assure
you that we will be able to purchase launch insurance or in-orbit insurance. In
addition, the insurance premiums we pay may increase substantially upon any
adverse change in insurance market conditions.

                                       17



<PAGE>

     Many risks we face may not be covered by insurance. Our insurance may not
cover all of our losses, and may not fully reimburse us for the following:

      expenditures for a satellite which fails to perform to specifications
      after launch;

      damages from business interruption, loss of business and any expenditures
      arising from satellite failures or launch delays; and

      losses for which there are deductibles, exclusions and conditions.

OUR TECHNOLOGY MAY BECOME OBSOLETE

     We will depend on technologies being developed by third parties to
implement key aspects of our system. These technologies may become obsolete. We
may be unable to obtain more advanced technologies on a timely basis or on
reasonable terms, or our competitors may obtain more advanced technologies and
we may not have access to these technologies.

RECEIVERS AND ANTENNAS ARE NOT YET AVAILABLE

     To receive the CD Radio service, a subscriber will need to purchase a
device capable of receiving our broadcasts as well as an appropriate antenna.
Although we have entered into an agreement with Lucent to develop and
manufacture chip sets that represent the essential element of CD Radio
receivers, we cannot assure you that Lucent will succeed in this development
effort. We have also entered into agreements with Delco, Recoton, Alpine and
Matsushita to design and develop devices capable of receiving CD Radio
broadcasts and antennas for use with these devices. We cannot assure you that
Delco, Recoton, Alpine or Matsushita will succeed in their development efforts.

     No one currently manufactures devices capable of receiving CD Radio
broadcasts and suitable antennas, and none of Delco, Recoton, Alpine and
Matsushita has agreed to manufacture commercial quantities of these devices. We
do not intend to manufacture or distribute CD Radio receivers and antennas
ourselves. We have discussed the manufacture of CD Radio receivers and antennas
for retail sale in the United States with several manufacturers, including
Delco, Visteon, Recoton, Alpine and Matsushita. These discussions may not result
in a binding commitment on the part of any manufacturer to produce, market and
sell devices capable of receiving CD Radio broadcasts and suitable antennas in a
timely manner and at a price that would permit the widespread introduction of
CD Radio in accordance with our business plan. In addition, any manufacturers of
devices capable of receiving CD Radio broadcasts and antennas may not produce
them in sufficient quantities to meet anticipated consumer demand. Our business
would be materially adversely affected if we cannot arrange for the timely
development of these products for commercial sale at an affordable price and
with sufficient retail distribution.

     Our FCC license requires that we design a receiver that is interoperable
with the national satellite radio system being developed by the other existing
licensee, XM Satellite Radio Inc. Although we have made progress towards
designing a receiver that is interoperable with the system XM is constructing,
we cannot predict whether we will be able to satisfy this interoperability
requirement because of the various technological challenges involved. Complying
with this interoperability requirement also could make the devices capable of
receiving CD Radio broadcasts and the related antenna more difficult and costly
to manufacture. Accordingly, this interoperability requirement could delay the
commercial introduction of these products or require that they be sold at higher
prices.

WE MAY NOT BE ABLE TO COMPETE EFFECTIVELY AGAINST CONVENTIONAL RADIO STATIONS,
THE OTHER HOLDER OF AN FCC LICENSE TO PROVIDE THIS SERVICE OR OTHER POTENTIAL
PROVIDERS OF THIS SERVICE

     We will be competing with established conventional (over the air) radio
stations, which, unlike CD Radio:

      do not charge subscription fees;

      do not require users to purchase a separate receiver and antenna;

      often offer local information programming such as local news and traffic
      reports; and

                                       18



<PAGE>

      in the case of some FM stations, may begin to broadcast digital, compact
      disc quality signals before we start operations.

     In addition to direct competition from XM, we face the possibility of
additional satellite broadcast radio competition:

      if the FCC grants additional licenses for satellite-delivered radio
      services;

      if holders of licenses for other portions of the electromagnetic spectrum
      (currently licensed for other uses) obtain changes to their licenses; or

      if holders of licenses without FCC restrictions for other portions of the
      spectrum devise a method of broadcasting satellite radio.

     Finally, one or more competitors may design a satellite radio broadcast
system that is superior to our system. The competitive factors listed above
could materially adversely affect our results of operations. In addition, any
delays in introducing our service also could place us at a competitive
disadvantage relative to any competitor that begins operations before us.

WE MAY NOT BE ABLE TO SUCCESSFULLY MANAGE RAPID GROWTH

     We expect to experience significant and rapid growth in the scope and
complexity of our business as we proceed with the development of our satellite
radio system. As of the date of this prospectus, we do not currently employ
sufficient staff to program our broadcast service, manage operations, control
the operation of our satellites or handle sales and marketing efforts. Although
we have hired experienced executives in these areas, we must hire many
additional employees before we begin commercial operations of our service. This
growth is likely to place a substantial strain on our management and operational
resources. Our results of operations could be materially adversely affected if
we fail to do any of the following:

      develop and implement effective management systems;

      hire and train sufficient personnel to perform all of the functions
      necessary to effectively provide our service;

      manage our subscriber base and business; or

      manage our growth effectively.

WE ARE SUBJECT TO CONTINUING AND DETAILED REGULATION BY THE FCC

     Our FCC license is being challenged. On October 10, 1997, the FCC's
International Bureau granted us an FCC license after we submitted a winning bid
in an FCC auction. One of the low-bidders in the FCC auction applied to have the
full FCC review the grant of our FCC license. The application requests that the
FCC adopt restrictions on foreign ownership and overrule the granting of our FCC
license on the basis of our ownership. If the FCC denies this application, the
complaining party may appeal to the U.S. Court of Appeals. Because less than 25%
of our voting stock is owned by non-U.S. persons, we believe the FCC will uphold
the grant of our FCC license. We cannot predict the ultimate outcome of any
proceedings relating to this application or any other proceedings that
interested parties may file. Since December 29, 1997, there have been no
developments in this matter.

     We need a modification to our FCC license before we can begin operation. In
May 1998, we decided to increase the number of satellites in our system from two
to three and to change the orbit of those satellites. To implement these
changes, the FCC must approve changes to our FCC license. If the FCC were to
deny our application to modify our license, we would be required to redesign our
proposed system and modify our satellites, at a significant cost, and our
commercial operations would be delayed. On December 11, 1998, we filed an
application with the FCC for these changes. Although we believe that the FCC
will approve our application for this necessary change, we cannot assure you
that this will occur. XM and WCS Radio, Inc. have filed comments objecting to
this modification of our FCC license. The FCC staff has requested additional
materials from us, and we are in the process of complying with the staff's
request. We cannot predict the time it will take the FCC to act on our
application or any of these objections, or whether

                                       19



<PAGE>

additional submissions or waiver requests will be necessary, and we cannot be
sure that the modification we have requested will be granted.

     We will need to renew our FCC license after eight years. The term of our
FCC license with respect to each satellite is eight years, beginning on the date
it is declared operational after it is inserted into orbit. When the term of our
FCC license for each satellite expires, we must apply for a renewal of the
relevant license. If the FCC does not renew our FCC license, we would be forced
to cease broadcasting CD Radio. We cannot assure you that we will obtain these
renewals.

     We need FCC approval to operate our terrestrial repeating transmitters.
Although we plan to install terrestrial repeating transmitters to rebroadcast
CD Radio in some urban areas, the FCC has not yet established rules governing
the application procedure for obtaining authorizations to construct and operate
terrestrial repeating transmitters on a commercial basis. The FCC initiated a
rulemaking on the subject in March 1997 and received several comments urging the
FCC to consider placing restrictions on the ability to deploy terrestrial
repeating transmitters. We cannot predict the outcome of this process.

     The United States needs to complete frequency coordination with Mexico. To
use our assigned spectrum, the United States government must complete a process
of frequency coordination with Mexico. We cannot assure you that the United
States government will be able to coordinate use of this spectrum with Mexico or
do so in a timely manner. The United States and Canadian governments were
required to complete a similar process and have done so.

     New devices may interfere with CD Radio broadcasts. The FCC has proposed
regulations to allow a new type of lighting device that may generate radio
energy in the part of the spectrum we intend to use. We believe the current
proposed regulations for these devices do not contain adequate safeguards to
prevent interference with services such as CD Radio. If the FCC fails to adopt
adequate technical standards specifically applicable to these devices and if the
use of these devices becomes commonplace, we could experience difficulties
enforcing our rights. If the FCC fails to adopt adequate standards, the new
devices could materially adversely affect reception of our broadcasts. Although
we believe that the FCC will set adequate standards to prevent harmful
interference, we cannot assure you that it will do so.

     We may be adversely affected by changing regulations. To provide CD Radio,
we must retain our FCC license and obtain or retain other requisite approvals.
Our ability to do so could be affected by changes in laws, FCC regulations,
international agreements governing communications policy generally or
international agreements relating specifically to CD Radio. In addition, the
manner in which CD Radio would be offered or regulated could be affected by
these changes.

     We may be adversely affected by foreign ownership restrictions. The
Communications Act of 1934 restricts ownership in some broadcasters by
foreigners. If these foreign ownership restrictions were applied to us, we would
need further authorization from the FCC if our foreign ownership were to exceed
25%. The order granting our FCC license determined that, as a private carrier,
those restrictions do not apply to us. However, the order granting our FCC
license stated that our foreign ownership status under the Communications Act
could be raised in a future proceeding. The pending appeal of the grant of our
FCC license may bring the question of foreign ownership restrictions before the
full FCC.

     We could be required to comply with public service regulations. The FCC has
indicated that it may impose public service obligations on satellite radio
broadcasters in the future, which could add to our costs or reduce our revenues.
For example, the FCC could require broadcasters to set aside channels for
educational programming. We cannot predict whether the FCC will impose public
service obligations or the impact that any of these obligations would have on
our results of operations.

CONSUMERS MAY STEAL OUR SERVICE

     Consumers may steal the CD Radio signal. Although we plan to use encryption
technology to mitigate signal piracy, we do not believe that this technology is
infallible. Accordingly, we cannot assure you that we can eliminate theft of the
CD Radio signal. Widespread signal theft could

                                       20



<PAGE>

reduce the number of motorists willing to pay us subscription fees and
materially adversely affect our results of operations.

OUR PATENTS MAY NOT BE SUFFICIENT TO PREVENT OTHERS FROM COPYING ELEMENTS OF OUR
SYSTEM

     Although our U.S. patents cover various features of satellite radio
technology, our patents may not cover all aspects of our system. Others may
duplicate aspects of our system which are not covered by our patents without
liability to us. In addition, competitors may challenge, invalidate or
circumvent our patents. We may be forced to enforce our patents or determine the
scope and validity of other parties' proprietary rights through litigation. In
this event, we may incur substantial costs and we cannot assure you of success
in this litigation. In addition, others may block us from operating our system
if our system infringes their patents, their pending patent applications which
mature into patents or their inventions developed earlier which mature into
patents. Should we desire to license our technology, we cannot assure you that
we can do so. Assuming we pay all necessary fees on time, the earliest
expiration date on any of our patents is April 10, 2012.

WE MAY NOT BE ABLE TO SATISFY A CHANGE OF CONTROL OFFER

     The indentures governing our senior secured notes, our senior secured
discount notes and our convertible subordinated notes and the certificates of
designations for our Series C Preferred Stock, 9.2% Series A Junior Cumulative
Convertible Preferred Stock and 9.2% Series B Junior Cumulative Convertible
Preferred Stock contain provisions that apply to a change of control of our
company. Additionally, our future securities may contain similar provisions. If
someone triggers a change of control as defined in those instruments or in our
future instruments, we must offer to purchase those securities. If we have to
make such an offer, we cannot be sure that we will have enough funds to pay for
all the securities that holders could tender. If we fail to pay for our senior
secured notes, our senior secured discount notes and our convertible
subordinated notes in a change of control offer, we will be in default under the
indentures for the affected notes and the holders of these notes and their
trustees may demand that we prepay all amounts outstanding under these notes. If
we fail to pay for the Series C Preferred Stock in a change of control offer,
the holders of a majority of this class of stock will be able to elect directors
constituting at least 25% of our board of directors, up to a maximum of two
directors. If we fail to pay for the 9.2% Series A Junior Cumulative Convertible
Preferred Stock and the 9.2% Series B Junior Cumulative Convertible Preferred
Stock in a change of control offer because of our obligations to other holders
of our debt securities or preferred stock, we must use our best efforts to
satisfy these obligations or to obtain permission to repurchase these classes of
preferred stock. Any of our future securities may have similar provisions.

THE SECURITY FOR THE NOTES MAY NOT BE SUFFICIENT TO MAKE PAYMENTS ON THE NOTES

     Our obligations under our senior discount notes indenture and our senior
discount notes are, and our obligations under the indenture and the notes are,
secured by a pledge of the Pledged Stock. We cannot assure you that proceeds
from the sale of the Pledged Stock will be sufficient to satisfy amounts due on
the notes. Satellite CD Radio, Inc. conducts no business activities and its only
asset is our FCC license. The notes are not secured by any lien on, or other
security interest in, any of our other properties or assets or any properties or
assets of Satellite CD Radio, Inc., except that during the first three years
after the date the notes are issued, the notes are secured by a portfolio of
U.S. government securities in an amount sufficient to pay the first six payments
of interest on the notes. In addition, the indenture permits us to incur other
secured indebtedness which may, in the future, be secured on an equal basis with
the notes with respect to the Pledged Stock.

     If, upon a foreclosure on the Pledged Stock, the proceeds from the Pledged
Stock are insufficient to satisfy the entire amount due on the notes and on the
Senior Discount Notes, the claim by the holders of the notes against us for this
deficiency would rank equally with the claims of the other general,
unsubordinated creditors of CD Radio. We cannot assure you that the remaining
assets of CD Radio would be sufficient to satisfy this deficiency.

                                       21



<PAGE>

     The trustee under the indenture may not exercise any rights with respect to
the Pledged Stock upon the occurrence of an Event of Default (as defined in the
indenture) if this action would constitute, or result in any, assignment of our
FCC license or any change of our control unless the prior approval of the FCC is
first obtained. We cannot assure you that any required FCC approval can be
obtained on a timely basis, or at all.

CONTROL BY EXISTING STOCKHOLDERS

     As of October 14, 1999, our executive officers and directors beneficially
owned or could vote approximately 22.3% of our outstanding common stock. In
addition, as of that date, our executive officers and directors together with
Prime 66 and the Apollo Investors beneficially owned or could vote approximately
51.3% of our outstanding common stock (assuming conversion of the Junior
Preferred Stock). As a result of this concentration of ownership, these
stockholders, if they choose to act in concert, may control or exert
considerable influence over our management and policies. Similarly, some or all
of these stockholders could delay, defer or prevent a change of control.

THERE IS NO PUBLIC MARKET FOR THE NOTES

     Before the offering of the notes, there has been no public market for the
notes and we do not intend to apply for the listing of the notes on any
securities exchange or for quotation of the notes on The Nasdaq Stock Market,
Inc. We have been advised by the initial purchasers that they presently intend
to make a market in the exchange notes, as permitted by applicable laws and
regulations. The initial purchasers are not obligated, however, to make a market
in the exchange notes and any market making activity may be discontinued at any
time without notice at the sole discretion of each initial purchaser. This
market-making activity will be restricted by limitations imposed by the
Securities Act and the Exchange Act, and may be limited during our exchange
offer for the notes. We cannot assure you as to the liquidity of the public
market for the exchange notes or that an active public market for the exchange
notes will develop. If an active public market does not develop, the market
price and liquidity of the exchange notes may be adversely affected. Please
refer to the section in this prospectus entitled 'Plan of Distribution.'

     Historically, the market for non-investment grade debt has been affected by
disruptions that have caused substantial volatility in the prices of securities
similar to the exchange notes. We cannot assure you that any market for the
exchange notes will not be affected by similar disruptions.

THE ISSUANCE OF THE EXCHANGE NOTES MAY ADVERSELY AFFECT THE MARKET FOR THE
INITIAL NOTES

     If initial notes are tendered for exchange and accepted in the exchange
offer, the trading market for the untendered and tendered but unaccepted initial
notes could be adversely affected. Please refer to the section in this
prospectus entitled ' -- Your failure to participate in the exchange offer will
have adverse consequences.'

YOUR FAILURE TO PARTICIPATE IN THE EXCHANGE OFFER WILL HAVE ADVERSE CONSEQUENCES

     The initial notes were not registered under the Securities Act or under the
securities laws of any state and you may not resell them, offer them for resale
or otherwise transfer them unless they are subsequently registered or resold
under an exemption from the registration requirements of the Securities Act and
applicable state securities laws. If you do not exchange your initial notes for
exchange notes pursuant to this exchange offer, or if you do not properly tender
your initial notes in this exchange offer, you will not be able to resell, offer
to resell or otherwise transfer the initial notes unless they are registered
under the Securities Act or unless you resell them, offer to resell or otherwise
transfer them under an exemption from the registration requirements of, or in a
transaction not subject to, the Securities Act. In addition, you may no longer
be able to obligate us to register the initial notes under the Securities Act.

                                       22



<PAGE>

SOME PERSONS WHO PARTICIPATE IN THE EXCHANGE OFFER MUST DELIVER A PROSPECTUS IN
CONNECTION WITH RESALES OF THE EXCHANGE NOTES

     Based on certain no-action letters issued by the staff of the Commission,
we believe that you may offer for resale, resell or otherwise transfer the
exchange notes without compliance with the registration and prospectus delivery
requirements of the Securities Act. However, in some instances described in this
prospectus under 'The Exchange Offer,' you will remain obligated to comply with
the registration and prospectus delivery requirements of the Securities Act to
transfer your exchange notes. In these cases, if you transfer any exchange note
without delivering a prospectus meeting the requirements of the Securities Act
or without an exemption from registration of your exchange notes under the
Securities Act, you may incur liability under this act. We do not and will not
assume, or indemnify you against, this liability.

HOLDERS OF EXCHANGE NOTES WILL BE TAXED ON ORIGINAL ISSUE DISCOUNT

     The exchange notes will be deemed to be issued at a substantial discount
from their principal amount. Consequently, holders of exchange notes generally
will be required to include amounts in gross income for United States federal
income tax purposes in advance of receipt of the cash payments to which this
income is attributable. If the exchange notes are treated as 'applicable high
yield discount obligations,' our deductions with respect to the original issue
discount on the exchange notes will be either deferred until we make the
related payments or possibly, in part, disallowed. Please refer to the section
in this prospectus entitled 'Certain United States Federal Income Tax
Considerations' for a more detailed discussion of the United States federal
income tax consequences to holders of the purchase, ownership and disposition of
the exchange notes and of the possible deferral or disallowance (in part) of
original issue discount deductions to us.

     If a bankruptcy case is commenced by or against us under the United States
Bankruptcy Code after the issuance of the exchange notes, the claim of a holder
of exchange notes may be limited to an amount equal to the sum of (1) the
initial public offering price for the notes and (2) that portion of the original
issue discount that is not deemed to constitute 'unmatured interest' for
purposes of the United States Bankruptcy Code. Any original issue discount that
was not amortized as of the date of the commencement of this bankruptcy filing
would constitute 'unmatured interest.'

                                       23







<PAGE>

                                USE OF PROCEEDS

     We will not receive any cash proceeds from the issuance of the exchange
notes in exchange for the initial notes. We are making this exchange solely to
satisfy our obligations under our registration rights agreement. In
consideration for issuing the exchange notes, we will receive initial notes in
aggregate value equal to the value of the exchange notes.

SOURCES AND USES OF FUNDS BY CD RADIO

     The following table describes our estimated sources and uses of funds from
our inception through the end of the fourth quarter of 2000, when we expect to
commence operations. Assuming the availability of the funds committed or
identified to date, we anticipate that we will exceed our pre-operational
funding requirements by $46 million. However, we anticipate funding requirements
of $150 million to fund our operations through the first full year of
operations. The projection of total sources and total uses of funds is forward
looking and could vary, perhaps substantially, from actual sources and uses, due
to events outside our control, including unexpected costs and unforeseen delays.
Please refer to the section in this prospectus entitled 'Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Special Note
Regarding Forward Looking Statements.'

(1) Consists of (a) our existing credit facility provided by Bank of America and
    other lenders in an aggregate principal amount of up to $115 million,
    (b) $50 million of vendor financing provided by Loral and (c) an additional
    credit facility Bank of America may (but is not obligated to) arrange for
    us. Net proceeds to us from the credit facilities referred to in
    clauses (a) and (c) above give effect to aggregate expenses of approximately
    $6 million. Our existing credit facility matures on the earlier of
    February 29, 2000 and ten days prior to the launch of our second satellite.
    We have entered into an agreement with Bank of America under which Bank of

    America has agreed to attempt to arrange a syndicate of lenders to provide
    the term loan facility referred to in clause (c) above in the aggregate
    principal amount of $225 million (of which $115 million would be used to
    repay the existing credit facility). Bank of America has not committed to
    provide these loans and we cannot assure you that these loans will be
    arranged or the terms of these loans will be acceptable to us. The
    availability of these loans when required to repay amounts outstanding at
    maturity under our existing credit facility will be influenced by a variety
    of factors, some of which, including the market for syndicated bank loans
    generally, are outside of our control. See 'Description of Certain
    Indebtedness -- Vendor Financing' and 'Management's Discussion and Analysis
    of Financial Condition and Results of Operations -- Liquidity and Capital
    Resources.'

(2) Includes proceeds from sale of related warrants.

(3) Includes net proceeds of (a) approximately $121 million from the issuance
    of 5,400,000 shares of 5% Preferred Stock in a private placement,
    (b) approximately $129 million from the issuance of 1,350,000 shares of our
    9.2% Series A Junior Cumulative Convertible Preferred Stock to the Apollo
    Investors and (c) approximately $63 million from the issuance of 650,000
    shares of our 9.2% Series B Junior Cumulative Convertible Preferred Stock to
    the Apollo Investors.

(4) Includes (a) an aggregate of $22 million, including from the sale of common
    stock and warrants, raised before the award of our FCC license, (b) $24.5
    million of net proceeds from the sale of 1,905,488 shares of common stock to
    Loral Space & Communications Ltd. in August 1997, (c) $46.4 million of net
    proceeds from the sale of 3,050,000 shares of common stock in a public
    offering in November 1997, (d) $98 million of net proceeds from the sale of
    5,000,000 shares of common stock to Prime 66 in November 1998 and (e) $78
    million of net proceeds from the sale of 3,450,000 shares of common stock in
    a public offering in September and October 1999.

(5) If Bank of America is unable to arrange a new credit facility, we will need
    to raise $115 million to refinance the existing credit facility in the first
    quarter of 2000 and an additional $60 million to fund our operations through
    the end of the fourth quarter of 2000.

(6) This amount includes $15 million of long-lead time parts for a fifth
    satellite and $3 million for integration analysis of the viability of using
    the Sea Launch platform as an alternative launch vehicle for our satellites.
    As of August 31, 1999, we had satisfied $376 million under the Loral
    Satellite Contract.

(7) Includes (a) an estimated $58 million for the construction and development
    of our National Broadcast Studio, which includes costs associated with the
    acquisition of programming, the purchase of tracking, telemetry and control
    equipment and the construction of two earth stations in South America by
    Loral Skynet, and (b) an estimated $62 million for terrestrial repeaters.

(8) Includes (a) cumulative historical cash operating expenses through June 30,
    1999 of approximately $66 million, including $25.7 million of expenses
    resulting primarily from our termination of our launch agreement with
    Arianespace, and (b) projected operating and other capital expenses,
    including operation of our terrestrial repeater network, pre-operational
    marketing expenses, expenses relating to the development of receivers and
    other general and administrative expenses from July 1, 1999 through the end
    of the pre-operational period of $131 million.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     This prospectus contains some forward-looking statements within the meaning
of the federal securities laws. Actual results and the timing of some events
could differ materially from those projected in the forward-looking statements
due to a number of factors, including those described under 'Risk Factors' and
elsewhere in this prospectus. See 'Special Note Regarding Forward Looking
Statements' below.

OVERVIEW

     CD Radio was organized in May 1990 and is in its development stage. Our
principal activities to date have included technology development, terrestrial
repeater network development, arranging for design and development of chip sets
and receivers, obtaining regulatory approval for the CD Radio service,
commencement of construction of four satellites, acquisition of content for our
programming, strategic planning, market research, recruitment of our management
team and securing financing for working capital and capital expenditures. We do
not expect to generate any revenues from operations until the first quarter of
2001, at the earliest, and we expect that positive cash flow from operations
will not be generated until the third quarter of 2001, at the earliest. In
addition, we require additional capital to complete development and commence
operations of CD Radio. Our actual funding requirements could materially exceed
our projections, due to a variety of factors, some of which are outside of our
control. We cannot assure you that we will ever commence operations, that we
will attain any particular level of revenues or that we will achieve
profitability. For further information about these risks, please refer to the
section of the related prospectus entitled 'Risk Factors.'

     Upon commencing operations, we expect our primary source of revenues to be
monthly subscription fees. We currently anticipate that our subscription fee
will be approximately $9.95 per month to receive CD Radio broadcasts, with a one
time, modest activation fee per subscriber. In addition, we expect to derive
additional revenues from directly selling or bartering advertising time on our
non-music channels. We do not intend to manufacture the consumer electronic
devices necessary to receive CD Radio and thus will not receive any revenues
from their sale. Although we hold patents covering some of the technology which
will be used in these consumer electronic devices, we expect to license our
technology to manufacturers at no charge.

     We expect that the operating expenses associated with operations will
consist primarily of marketing, sales, programming, maintenance of the satellite
and broadcasting system and general and administrative costs. Costs to acquire
programming are expected to include payments to build and maintain an extensive
music library and royalty payments for broadcasting music (calculated based on a
percentage of revenues). Marketing, sales, general and administrative costs are
expected to consist primarily of advertising costs, salaries of employees, rent
and other administrative expenses. As of October 8, 1999, we had 77 employees
and 21 part-time consultants. We expect to have approximately 150 employees by
the time we commence operations.

     In addition to funding initial operating losses, we require funds for
working capital, interest and financing costs on borrowings and capital
expenditures in the near term.

RESULTS OF OPERATIONS

SIX MONTHS ENDED JUNE 30, 1999 COMPARED WITH SIX MONTHS ENDED JUNE 30, 1998

     We recorded net losses of $23,045,000 and $36,015,000 for the six months
ended June 30, 1999 and 1998, respectively. Our total operating expenses were
$25,762,000 and $30,898,000 for the six months ended June 30, 1999 and 1998,
respectively. Excluding the special charges totaling $25.7 million recorded in
the 1998 second quarter, we recorded a net loss of $10,333,000 and operating
expenses of $5,216,000 for the six months ended June 30, 1998.

     Engineering design and development costs were $14,344,000 and $774,000 for
the six months ended June 30, 1999 and 1998, respectively. Engineering costs
increased in the 1999 period

                                       29



<PAGE>

primarily due to payments to Lucent in connection with the chip set development
effort and payments to consumer electronic manufacturers in connection with
receiver development efforts.

     General and administrative expenses increased for the six months ended June
30, 1999 to $11,418,000 from $4,442,000 for the six months ended June 30, 1998.
General and administrative expenses increased due to the occupancy of our new
offices and national broadcast studio and the growth of our management team and
the workforce necessary to develop and commence the broadcast of CD Radio. The
major components of general and administrative expenses in the 1999 period were
salaries and employment related costs (30%), rent and occupancy costs (25%) and
legal and regulatory fees (14%), while in the 1998 period the major components
were salaries and employment related costs (27%), rent and occupancy costs
(16%), and legal and regulatory fees (15%). The remaining portion of general and
administrative expenses (31% in the 1999 period and 42% in the 1998 period)
consisted of other costs such as insurance, market research, consulting, travel,
depreciation and supplies, with no such amount exceeding 10% of the total in the
1999 period and only consulting (16%) exceeding 10% of the total in the 1998
period.

     The increase of interest income to $6,400,000 for the six months ended June
30, 1999, from $3,903,000 in the six months ended June 30, 1998, was the result
of higher average balances of cash, marketable securities and restricted
investments during the 1999 period. The higher average balances of cash,
marketable securities and restricted investments during the period were due to
the proceeds from the issuance of notes in the second quarter of 1999 and stock
sales during the fourth quarter of 1998 exceeding the amount of expenditures for
satellite and launch vehicle construction, other capital expenditures and
operating expenses.

     Interest expense, net of capitalized interest, decreased to $3,683,000 for
the six months ended June 30, 1999, from $8,982,000 in the 1998 period. This
decrease in net interest expense was due to capitalized interest increasing by
an amount ($20,326,000) greater than the corresponding increase in interest
expense ($15,027,000).

YEAR ENDED DECEMBER 31, 1998 COMPARED WITH YEAR ENDED DECEMBER 31, 1997

     We recorded net losses of $48,396,000 ($2.70 per share) for the year ended
December 31, 1998 and $4,737,000 ($.41 per share) for the year ended
December 31, 1997. Our total operating expenses were $39,079,000 in 1998 and
$6,865,000 in 1997. Excluding the special charges recorded in the second quarter
of 1998 totaling $25,682,000 which related primarily to the termination of
certain launch and orbit related contracts required when we decided to enhance
our satellite delivery system to include a third in-orbit satellite, we recorded
net losses of $22,714,000 and operating costs of $13,397,000 in 1998.

     Legal, consulting and regulatory fees increased to $4,064,000 in 1998 from
$3,236,000 in 1997. The increase in the level of expenditures was primarily the
result of greater consulting expenses due to the accelerated execution of our
business plan. Consulting fees were generated primarily in connection with the
technical aspects of our business plan, such as satellite construction, chip set
design and terrestrial repeater network build-out. The major components of
legal, consulting and regulatory fees in the 1998 period were legal (48%),
consulting (50%) and regulatory (2%), while in the 1997 period the major
components were legal (51%), consulting (44%) and regulatory (5%).

     Research and development costs were $22,000 in 1998, compared with $57,000
in 1997. This level of research and development cost is the result of our
completing the majority of these activities in 1994.

     Other general and administrative expenses increased to $9,311,000 in 1998
from $3,572,000 in 1997. General and administrative activities have grown as we
continue to expand our management team and the workforce necessary to develop
and commence the broadcast of CD Radio. The major components of other general
and administrative costs in 1998 were salaries and employment related costs
(51%) and rent and occupancy costs (24%), while in the 1997 period the major
components were salaries and employment related costs (57%) and rent and
occupancy costs (11%). The increase in the percentage of the total costs related
to rent and occupancy was due to our taking possession of the premises where our
National Broadcast Studio is being constructed.

                                       30



<PAGE>

The remaining portion of other general and administrative costs (25% in 1998 and
32% in 1997) consists of other costs such as insurance, market research, travel,
depreciation and supplies, with no amount exceeding 10% of the total.

     Interest and investment income increased to $7,250,000 in 1998 from
$4,074,000 in 1997. The increase was the result of a higher average investment
balance throughout 1998 than 1997. The higher average investment balance was due
to the completion of the sales of stock to both Prime 66 and the Apollo
Investors in 1998 and the unexpended proceeds from our 1997 securities
offerings.

     Interest expense, net of capitalized interest, was $14,272,000 in 1998 and
$1,946,000 in 1997. This increase was due to interest expense accruing on our
senior secured discount notes issued in November 1997. Although we recorded a
net loss, we recorded $2,295,000 of income tax expense in 1998, which is related
to our being a 'start-up' company for income tax purposes and the fact that the
interest expense on our senior secured discount notes is deductible only when
paid.

YEAR ENDED DECEMBER 31, 1997 COMPARED WITH YEAR ENDED DECEMBER 31, 1996

     We recorded net losses of $4,737,000 ($.41 per share) for the year ended
December 31, 1997 and $2,831,000 ($.29 per share) for the year ended
December 31, 1996. Our total operating expenses were $6,865,000 for the year
ended December 31, 1997 and $2,930,000 for the year ended December 31, 1996.

     Legal, consulting and regulatory fees increased for the year ended
December 31, 1997 to $3,236,000 from $1,582,000 for the year ended December 31,
1996. These levels of expenditures are the result of increased activity since
winning the auction for our FCC license in April 1997, and in connection with
our public offerings of Common Stock and units consisting of Senior Discount
Notes and warrants to purchase Senior Discount Notes and the exchange offer for
our 5% Preferred Stock. The major components of legal, consulting and regulatory
fees in 1997 were legal (51%), consulting (44%) and regulatory (5%), while in
1996 the major components were legal (48%), consulting (38%) and regulatory
(14%).

     Research and development costs were $57,000 for the year ended
December 31, 1997 and $117,000 for the year ended December 31, 1996. We
completed the majority of these activities in 1994.

     Other general and administrative expenses increased for the year ended
December 31, 1997 to $3,572,000 from $1,231,000 for the year ended December 31,
1996. General and administrative expenses are expected to continue to increase
as we continue to develop our business. The major components of other general
and administrative costs in 1997 were salaries and employment related costs
(57%) and rent and occupancy costs (11%), while in 1996 the major components
were salaries and employment related costs (50%) and rent and occupancy costs
(22%). The remaining portion of other general and administrative costs (32% in
1997 and 28% in 1996) consists of other costs such as insurance, market
research, travel, depreciation and supplies, with no amount exceeding 10% of the
total.

     The increase in interest and investment income to $4,074,000 for the year
ended December 31, 1997, from $112,000 in the year ended December 31, 1996, was
the result of a higher average investment balance during 1997. The investments
on hand were primarily obtained from the debt and equity offerings completed in
1997.

     Interest expense increased for the year ended December 31, 1997 to
$1,946,000 from $13,000 for the year ended December 31, 1996. The increase is
the result of the issuance of the units consisting of senior secured discount
notes and warrants to purchase senior secured discount notes in November 1997.

LIQUIDITY AND CAPITAL RESOURCES

     At June 30, 1999, we had a total of cash, cash equivalents, marketable
securities and restricted investments of $356,028,000 and working capital of
$204,693,000 compared with cash, cash

                                       31



<PAGE>

equivalents and marketable securities of $265,623,000 and working capital of
$180,966,000 at December 31, 1998. The increases in the respective balances are
due primarily to the proceeds from the issuance in May 1999 of units consisting
of our senior secured notes and warrants to purchase our common stock. As part
of the issuance of the senior secured notes in the 1999 second quarter, we were
required to place approximately $79.3 million of government securities in a
restricted account to be used only to pay the interest on these notes during
their first three years. Subsequent to June 30, 1999, we received an aggregate
of $278 million in net proceeds from the issuance of 3,450,000 shares of our
common stock, $143.75 million aggregate principal amount of our convertible
subordinated notes and 650,000 shares of our 9.2% Series B Junior Cumulative
Convertible Preferred Stock.

     Funding Requirements. We require near-term funding to continue building our
CD Radio system. We believe we can fund our planned operations and the
construction of our satellite system into the fourth quarter of 2000 from the
proceeds of this stock offering, the notes offering and from our working
capital. We estimate that we will require approximately $1,170 million to
develop and commence commercial operations by the end of the fourth quarter of
2000. This amount is higher than our previous estimate and reflects additional
engineering requirements for our terrestrial repeater network, increases in
premiums in the market for satellite launch and in-orbit insurance, costs for
engineering analysis on potential alternative satellite launch platforms and
other increased operating costs. We have raised and identified sources of funds
for approximately $1,216 million (which includes sources of $115 million of debt
financing to repay our existing bank credit facility that must be repaid by the
earlier of February 29, 2000 and ten days prior to the launch of our second
satellite), leaving expected excess cash of approximately $46 million to fund
our operations after the fourth quarter of 2000. However, if Bank of America is
unable to arrange a new credit facility for us, we will need to raise $115
million to refinance the existing credit facility in the first quarter of 2000
and an additional $60 million to fund our operations through the end of the
fourth quarter of 2000. The availabilty of this new credit facility, which we
expect to draw on to repay amounts outstanding at maturity under our existing
bank credit facility, will be influenced by a variety of factors, some of which,
including the market for syndicated bank loans generally, are outside of our
control. In addition, we anticipate cash requirements of approximately $150
million to fund our operations through the first full year of commercial
operations. This amount is higher than our previous estimate and reflects
additional engineering design and development costs and increases in the amount
of chip set subsidies for CD Radio receivers, which are payable in part under
our recent agreements with Alpine, Panasonic and Ford, and costs of revenue
sharing with Ford. The amount also reflects increases in premiums in the market
for satellite in-orbit insurance and other increased operating costs. We expect
to finance the remainder of our funding requirements through the future issuance
of debt or equity securities, or a combination of debt and equity securities.

     To build and launch the satellites necessary for the operations of CD Radio
we entered into the Loral Satellite Contract. The Loral Satellite Contract
provides for Loral to construct, launch and deliver three satellites in-orbit
and checked-out, to construct for us a fourth satellite for use as a ground
spare and to become our launch services provider. We are committed to make
aggregate payments of approximately $736 million under the Loral Satellite
Contract, which includes $15 million of long-lead time parts for a fifth
satellite and $3 million for integration analysis of the viability of using the
Sea Launch platform as an alternative launch vehicle for our satellites. As of
August 31, 1999, $376 million of this obligation had been satisfied. Under the
Loral Satellite Contract, with the exception of a payment made to Loral in March
1993, payments are made in installments commencing in April 1997 and will end in
December 2003. Approximately half of these payments are contingent upon Loral
meeting specified milestones in the construction of our satellites.

     We also will require funds for working capital, interest on borrowings
(including the convertible subordinated notes), acquisition of programming,
financing costs and operating expenses until some time after the commencement of
commercial operations of CD Radio. We expect our interest expense will increase
significantly when compared to our 1998 interest expense as a result of the
issuance of our senior secured notes and the convertible subordinated notes;
however, our

                                       32



<PAGE>

senior discount notes, which represent a substantial portion of our planned
indebtedness, will not require cash payments of interest until June 2003. In
addition, a portion of the net proceeds of the issuance of our senior secured
notes was used to purchase a portfolio of U.S. government securities in an
amount sufficient to pay the first six payments of interest on these notes. In
addition, we currently expect to fund interest payments on the convertible
subordinated notes through proceeds from the issuance of equity. We cannot
assure you that such issuances will be accomplished on terms advantageous to us,
or at all.

     We cannot assure you that we will be able to obtain additional financing on
favorable terms, or at all, or that we will be able to do so in a timely
fashion. The indentures governing our senior secured notes and our senior
secured discount notes and the Tranche A Facility contain, and documents
governing any indebtedness incurred in the future are expected to contain,
provisions limiting our ability to incur additional indebtedness. If additional
financing were not available on a timely basis, we would be required to delay
satellite and/or launch vehicle construction to conserve cash and to fund
continued operations, which would cause delays in the commencement of operations
and increase costs.

     The amount and timing of our actual cash requirements will depend upon
numerous factors, including costs associated with the construction and
deployment of our satellite system and terrestrial repeater network, costs
associated with the design and development of chip sets and receivers, the rate
of growth of our business after commencing service, costs of financing and the
possibility of unanticipated costs. We will require additional funds if there
are delays, cost overruns, unanticipated expenses, launch failures, launch
services or satellite system change orders, or any shortfalls in estimated
levels of operating cash flow.

     Sources of Funding. To date, we have funded our capital needs through the
issuance of debt and equity securities and borrowings under our term loan
facility. As of October 14, 1999, we had received a total of $582 million in
equity capital. In 1997 we received a total of $192 million as a result of the
issuance of 5,400,000 shares of 5% Delayed Convertible Preferred Stock,
resulting in net proceeds of $121 million, and the issuance of 4,955,488 shares
of common stock, resulting in net proceeds of $71 million. In November 1997, we
exchanged 1,846,799 shares of our newly issued 10 1/2% Series C Cumulative
Convertible Preferred Stock for all of the outstanding shares of 5% Delayed
Convertible Preferred Stock. On November 2, 1998, we sold 5,000,000 shares of
common stock to Prime 66 resulting in net proceeds of $98 million and on
December 23, 1998, we sold 1,350,000 shares of 9.2% Series A Junior Cumulative
Convertible Preferred Stock to the Apollo Investors resulting in net proceeds of
$129 million. On December 23, 1998, the Apollo Investors also granted us an
option to sell them 650,000 shares of the 9.2% Series B Junior Cumulative
Convertible Preferred Stock which we exercised in October 1999 for net proceeds
of $63 million. In September and October 1999 we issued 3,450,000 shares of our
common stock in an underwritten public offering resulting in total net proceeds
of $78 million.

     The Junior Preferred Stock is convertible into shares of common stock at a
price of $30 per share. The Junior Preferred Stock is callable by us beginning
November 15, 2001 if the current market price, as defined in the Certificate of
Designation of the Junior Preferred Stock, of our common stock exceeds $60 per
share for a period of 20 consecutive trading days, and in all events will be
callable beginning November 15, 2003 at a price of 100% and must be redeemed by
us on November 15, 2011. Dividends on the Junior Preferred Stock are
payable-in-kind or cash annually, at our option. Holders of the Junior Preferred
Stock have the right to vote, on an as-converted basis, on matters in which the
holders of our common stock have the right to vote.

     In September and October 1999 we issued $143,750,000 aggregate principal
amount of our convertible subordinated notes in an underwritten public offering
resulting in total net proceeds of $137 million. In May 1999, we received net
proceeds of approximately $190 million from the issuance of 200,000 units, each
consisting of $1,000 aggregate principal amount of senior secured notes and
three warrants, each to purchase 3.65 shares of our common stock. We invested
approximately $79.3 million of the net proceeds of the senior secured notes in a
portfolio of U.S. government securities, which we pledged as security for the
payment in full of interest on the senior secured notes through May 15, 2002. As
required by the terms of the warrants, we adjusted the number of shares for
which each warrant may be exercised to 3.792 shares and the exercise

                                       33



<PAGE>

price per share to $27.53 per share on account of our issuance of 3,000,000
shares of our common stock and $125,000,000 principal amount of our convertible
subordinated notes on September 29, 1999.

     In November 1997, we received net proceeds of $116 million from the
issuance of 12,910 units, each consisting of $20,000 aggregate principal amount
at maturity of senior secured discount notes and a warrant to purchase
additional senior secured discount notes with an aggregate principal amount at
maturity of $3,000. All these warrants were exercised in 1997. The aggregate
value at maturity of the senior secured discount notes is $297 million. The
senior secured discount notes mature on November 15, 2007 and the first cash
interest payment is due in June 2003. The indentures governing the senior
secured notes and the senior secured discount notes contain some limitations on
our ability to incur additional indebtedness. The senior secured notes and the
senior secured discount notes are secured by a pledge of the stock of Satellite
CD Radio Inc., our subsidiary that holds our FCC license.

     On July 28, 1998, we entered into the Tranche A Facility with a group of
financial institutions (the 'Lenders'), including Bank of America as agent and a
lender, under which the Lenders agreed to provide us a term loan facility in an
aggregate principal amount of up to $115 million (the term loans under the
Tranche A Facility, the 'Tranche A Loans'). The proceeds of the Tranche A Loans
are being used to fund a portion of the progress payments required to be made by
us under the Loral Satellite Contract for the purchase of launch services and to
pay interest, fees and other expenses related to the Tranche A Facility. The
Tranche A Loans are due on the earlier of February 29, 2000 and ten days prior
to the launch of our second satellite. As of June 30, 1999, we had borrowed
$95.5 million under the Tranche A Facility, substantially all of which was used
to make progress payments under the Loral Satellite Contract.

     In connection with the Tranche A Facility, Loral agreed with Bank of
America that at maturity of the Tranche A Loans (including maturity as a result
of an acceleration), upon the occurrence of a bankruptcy of CD Radio or upon the
occurrence of an event of default by Loral under its agreement with Bank of
America, Loral will repurchase from the Lenders the Tranche A Loans at a price
equal to the principal amount of the Tranche A Loans plus accrued and unpaid
interest. In exchange for providing this credit support, Loral receives a fee
from us equal to 1.25% per annum of the outstanding amount of the Tranche A
Loans from time to time.

     We have also entered into an agreement with Bank of America under which
Bank of America has agreed to attempt to arrange a syndicate of lenders to
provide a term loan facility for us in the aggregate principal amount of $225
million. It is anticipated that a portion of the proceeds of these loans would
be used to repay amounts outstanding under the Tranche A Facility and for other
general corporate purposes. Bank of America has not committed to provide this
term loan facility. The availability of these loans when required to repay
amounts outstanding at maturity under the Tranche A Facility will be influenced
by a variety of factors, some of which, including the market for syndicated bank
loans generally, are outside of our control. The closing of this term loan
facility is expected to be conditioned on the satisfaction of specific
significant conditions and there is no assurance that these loans will be
arranged or that the proposed terms of these loans will be acceptable to us. If
we are unable to close this facility, we will seek to repay the Tranche A Loans
from the proceeds of the sale of debt securities, equity securities or a
combination of debt and equity securities.

     Loral has agreed to defer a total of $50 million of the payments under the
Loral Satellite Contract originally scheduled for payment in 1999. These
deferred amounts bear interest at 10% per annum and all interest on these
deferred amounts will accrue until December 2001, at which time interest will be
payable quarterly in cash. The principal amounts of the deferred payments under
the Loral Satellite Contract are required to be paid in six installments between
June 2002 and December 2003. As collateral security for these deferred payments,
we have agreed to grant Loral a security interest in our terrestrial repeater
network. If there is a satellite or launch failure, we will be required to pay
Loral the deferred amount for the affected satellite no later than 120 days
after the date of the failure. If we elect to put one of our first three
satellites into ground storage, rather than having it shipped to the launch
site, the deferred amount for that satellite will become due within 60 days of
this election.

OTHER MATTERS -- THE YEAR 2000 ISSUE

     The Year 2000 Issue will test the capability of business processes to
function correctly. We have undertaken an effort to identify and mitigate The
Year 2000 Issue in our information systems, product, suppliers and facilities.
Our approach to The Year 2000 Issue can be separated into four phases: (1)
define/measure -- identify and inventory possible sources of Year 2000 Issues;
(2) analyze -- determine the nature and extent of Year 2000 Issues and develop
project plans to address those issues; (3) improve -- execute project plans and
perform a majority of the testing; and (4) control -- complete testing, continue
monitoring readiness and complete necessary contingency plans. The first three
phases of the program have been completed for a substantial majority of our
mission-critical activities. Management plans to have nearly all significant
information systems and facilities through the control phase of the program by
late-1999.

     We have also communicated with our significant vendors and suppliers to
determine the extent to which we are vulnerable to the failure of these parties
to remedy Year 2000 Issues. We can give no assurance that failure to address the
Year 2000 Issues by third parties on whom our systems and business processes
rely would not have a material adverse effect on our operations or financial
condition.

     The total Year 2000 Issue remediation expenditures are expected to be
approximately $100,000 of which 50% was spent by June 30, 1999. Substantially
all of the remainder is expected to be spent in 1999. The activities involved in
the Year 2000 effort necessarily involve estimates and projections of activities
and resources that will be required in the future. These estimates and
projections could change as work progresses.

SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS

     The following cautionary statements identify important factors that could
cause our actual results to differ materially from those projected in the
forward looking statements made in this prospectus. Any statements about our
expectations, beliefs, plans, objectives, assumptions or future events or
performance are not historical facts and may be forward looking. These
statements are often, but not always, made 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.'
Accordingly, these statements involve estimates, assumptions and uncertainties
which could cause actual results to differ materially from those expressed in
them. Any forward looking statements are qualified in their entirety by
reference to the factors discussed throughout this prospectus, and particularly
the risk factors described under 'Risk Factors' in this prospectus. 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;

           risk of launch failure;

           unproven market and unproven applications of technology;

           our dependence on Loral and Lucent;

           unavailability of receivers and antennas; and

           our need for additional financing.

     These and other factors are discussed in 'Risk Factors' and elsewhere in
this prospectus.

     Because the risk factors referred to above could cause actual results or
outcomes to differ materially from those expressed in any forward looking
statements made by us or on our behalf, you should not place undue reliance on
any of these forward looking statements. Further, any forward looking statement
speaks only as of the date on which it 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 the statement is made or to reflect the
occurrence of unanticipated events. New factors emerge from time to time, and it
is not possible for us to predict which will arise. In addition, we cannot
assess with any precision the impact of each 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.

                                    BUSINESS

     We are building a digital quality radio service that will broadcast up to
100 channels directly from satellites to vehicles. CD Radio will be broadcast
throughout the continental United States, over a frequency band, the 'S-band,'
that will augment traditional AM and FM radio bands. We hold one of only two
licenses issued by the FCC to build, launch and operate a national satellite
radio broadcast system. Under our FCC license, we have the exclusive use of a
12.5 MHz portion of the S-band for this purpose. Our service, which will be
primarily for motorists, will offer 50 channels of commercial-free, digital
quality music programming and up to 50 channels of news, sports, talk and
entertainment programming. We currently expect to commence CD Radio broadcasts
at the end of the fourth quarter of 2000, at an anticipated subscription price
of $9.95 per month. We have entered into a contract with Loral for the
construction, launch and in-orbit delivery of three satellites beginning in
January 2000.

     As an entertainment company, we intend to design and originate programming
on each of our 50 commercial-free music channels. Each channel will be operated
as a separate radio station, with a distinct format. Some of the music channels
will offer continuous music while others will have program hosts, depending on
the type of music programming. CD Radio will offer the following range of music
categories:

 Symphonic
 Chamber Music
 Opera
 Top of the Charts
 50's Hits
 60's Hits
 70's Hits

     Programming on our non-music channels will be provided by third parties,
and to date we have entered into programming agreements with content providers
for 25 of these channels, including NPR, BBC, Bloomberg News Radio, C-SPAN and
Sports Byline USA. A majority of our non-music channels will contain
advertising, which will augment our subscription revenue. These channels will
include news and talk shows and special interest programming directed to a
diverse range of groups, including sports and outdoor enthusiasts, Hispanic
listeners and truck drivers.

     Our music and non-music channels will be broadcast from our National
Broadcast Studio in Rockefeller Center in New York City. The National Broadcast
Studio will contain our corporate headquarters, our music library, facilities
for programming origination, programming personnel and program hosts, and
facilities to transmit programming to our orbiting satellites, to activate or
deactivate service to subscribers and to perform the tracking, telemetry and
control of the satellites.

     On June 11, 1999, we entered into an agreement with Ford Motor Company
which anticipates Ford manufacturing, marketing and selling vehicles that
include receivers capable of receiving the CD Radio broadcasts. As part of this
exclusive agreement, Ford will be entitled to participate in a

                                       36



<PAGE>

portion of the revenues derived by us from new Ford vehicles equipped to receive
CD Radio broadcasts. In addition, we will reimburse Ford for specific costs of
equipping these Ford vehicles to receive CD Radio broadcasts and we have granted
Ford warrants to purchase up to 4,000,000 shares of our common stock at an
exercise price of $30 per share. Ford may exercise these warrants based upon the
number of Ford vehicles equipped to receive CD Radio broadcasts that Ford elects
to manufacture, and these warrants are fully exercisable upon 4,000,000 of these
vehicles being manufactured. Please refer to the section of the related
prospectus entitled 'Description of Warrants -- The Ford Warrant' for further
information regarding the Ford warrants.

     On September 23, 1999, we and Ford amended our agreement to extend the term
by one year and to enter into a cooperative advertising arrangement. As part of
the cooperative advertising arrangement, we have agreed to reimburse Ford for
portions of its direct, out-of-pocket, costs of advertising or media that
promote or mention CD Radio in association with Ford vehicles. Our obligation to
reimburse Ford for this cooperative advertising is limited to $3 million per
year during our first five years of commercial operations.

     We have entered into an agreement with Lucent for the development and
manufacture of a chip set that represents the essential element of consumer
electronics devices which are capable of receiving CD Radio.

     CD Radio Inc. was incorporated in the State of Delaware as Satellite
CD Radio, Inc. on May 17, 1990. On December 7, 1992, we changed our name to
CD Radio Inc., and we formed a wholly owned subsidiary, Satellite CD Radio,
Inc., that is the holder of our FCC license. Our executive offices are located
at 1221 Avenue of the Americas, New York, New York 10020, our telephone number
is (212) 584-5100 and our internet address is cdradio.com. The information on
our website is not part of this prospectus.

THE CD RADIO SERVICE

     CD Radio will offer motorists: (1) commercial-free music programming; (2) a
wide choice of finely focused music and non-music formats; and (3) nearly
seamless signal coverage throughout the continental United States.

     Commercial-Free Music Programming. CD Radio will provide 50 channels of
commercial-free music programming. Our market research indicates that a
principal complaint of radio listeners concerning conventional broadcast radio
is the frequency of commercials. Because CD Radio, unlike commercial AM and FM
stations, will be a subscription service, our music channels will not contain
commercials.

     Wide Choice Of Programming. CD Radio will offer subscribers a broad range
of programming formats and significant depth within each format. Each of our 50
music channels will have a distinctive format, such as opera, reggae, classic
jazz and children's entertainment, intended to cater to specific subscriber
tastes. In most markets, radio broadcasters target their programming to broad
audience segments and therefore offer limited formats. Even in the largest
metropolitan markets many of our planned formats are unavailable. Additionally,
we will provide news, sports and talk programming that is generally not
available on conventional radio.

     'Seamless' Signal Coverage. CD Radio will be available throughout the
continental United States, enabling listeners almost always to be within its
broadcast range. We expect that our nearly seamless signal will appeal to
motorists who frequently travel long distances, including truck drivers and
recreational vehicle owners, as well as commuters and others who outdrive the
range of their preferred FM radio broadcasts. In addition, we expect that our
broadcasts will appeal to the 45 million consumers who live in areas that
currently receive only a small number of FM stations.

     Our research indicates that there is a significant market for music and
other radio programming such as news, talk and sports delivered through advanced
radio technology. While television technology has advanced steadily -- from
black and white to color, from broadcast to cable and satellite, and from
ordinary to high-definition television -- the last major advance in radio
technology was the introduction of FM broadcasts.

                                       37

     CD Radio is primarily a service for motorists. The Yankee Group, a market
research organization, estimates that there will be approximately 200 million
registered private motor vehicles in the United States by the end of this year.
CD Radio will initially target a number of demographic groups among the drivers
of these vehicles, including 100 million commuters, 34 million of whom spend
over one hour commuting daily; 45 million Americans who live in markets served
by five or fewer radio stations; three million truck drivers; three million
owners of recreational vehicles; and approximately 30 million persons of
Hispanic origin.

     We believe there will be significant consumer demand for CD Radio. Market
research conducted for us by The Yankee Group shows that radio listeners today
are substantially dissatisfied with both AM and FM radio because of frequent
commercial interruptions, lack of variety in programming and loss of signal
strength. CD Radio's commercial-free music, wide variety of formats and nearly
seamless national coverage have been designed to address these key disadvantages
of existing commercial radio.

     According to Arbitron, in 1996, despite the fact that almost all vehicles
contained either a cassette or compact disc player, 87% of automobile commuters
listened to the radio an average of 50 minutes a day while commuting. According
to the Radio Advertising Bureau, each week radio reaches approximately 95% of
all Americans over the age of 12, with the average listener spending more than
three hours per weekday and more than five hours per weekend listening to the
radio. More than 40% of all radio listening is done in cars. In addition, in
1998, approximately 79% of total radio listening was to FM stations, which
primarily provides music programming, as compared with AM stations which devote
a greater proportion of their programming to talk and news.

     We believe that our ability to offer a wide variety of musical and
non-musical formats simultaneously throughout the continental United States will
enable us to tap significant unmet consumer demand for specialized programming.
The economics of the existing advertiser supported radio industry dictate that
conventional radio stations generally program for the greatest potential
audience. Even in the largest metropolitan areas, station formats are limited.
Nearly half of all commercial radio stations in the United States offer one of
only three formats: country, adult contemporary and news/talk, and the next
three most prevalent formats account for another 30% of all commercial radio
stations. Although niche music categories such as classical, jazz, rap, gospel,
oldies, soundtracks, new age music, children's programming and others accounted
for approximately 33% of sales of recorded music in 1998, these formats
generally are unavailable on existing radio stations in many markets. Even in
New York City, the nation's largest radio market, there are no radio stations
devoted solely to such programming as opera, blues, chamber music, soundtracks,
reggae and many others. CD Radio's wide choice of formats is expected to appeal
to the large number of currently underserved listeners. Furthermore, CD Radio's
ability to offer a number of channels devoted to each genre will enable
subscribers to listen to a wider range of music within their preferred format.

     The limited coverage area of conventional radio broadcasting means that
listeners often travel beyond the range of any single station. Unlike
conventional FM stations, which have an average range of only approximately 30
miles before reception fades, CD Radio's system is designed to cover the entire
continental United States, enabling listeners to enjoy virtually seamless
coverage. Our ability to broadcast nationwide will also allow us to serve
currently underserved radio markets.

     We also believe that CD Radio will have a competitive advantage over
conventional radio stations because our music channels will be commercial-free.
In contrast, conventional radio stations interrupt their broadcasts with up to
18 minutes of commercials in every hour of music programming, and most stations
also frequently interrupt programming with news, promotional announcements,
public service announcements and miscellaneous information. We believe that
consumers dislike frequent commercial interruptions and that 'station surfing'
to avoid them is common.

                                       38



<PAGE>

PROGRAMMING

     We intend to offer 50 channels of commercial-free, all-music programming
and up to 50 additional channels of other formats, such as all-news, all-sports
and all-talk programming. Each music channel will have a distinctive format,
intended to cater to specific subscriber tastes. We believe that 50 music
channels will enable us to 'superserve' our subscribers with a greater range of
choice of content within their preferred format than is currently offered by
terrestrial radio, even in the most widely broadcast formats. We expect that the
initial subscription fee for CD Radio, which will entitle subscribers to receive
all CD Radio channels, will be $9.95 per month.

     We have recruited 12 full-time and 13 consulting basis program managers
from the recording, broadcasting and entertainment industries to manage the
development of daily programming for each CD Radio music channel and intend to
recruit additional program managers. To be accessible to these industries, we
are building our National Broadcast Studio in Rockefeller Center in New York
City. Program managers also will coordinate our continuing market research to
measure audience satisfaction, refine channel definitions and themes and select
program hosts for those channels that will have hosts.

     Music programming will be selected from our music library. We intend to
create an extensive music library which will consist of a deep range of recorded
music in each genre broadcast. We have begun to acquire recordings for our music
library. Through September 13, 1999, we had acquired approximately 750,000
titles across a broad range of music genres. We expect that our music library
will consist of approximately 2,000,000 titles when we commence commercial
broadcasts of CD Radio. We expect to update our music library with new
recordings as they are released and, in some cases, we will seek to acquire
recordings that are no longer commercially available.

     In addition to our music channels, we expect to offer up to 50 channels of
news, sports and talk programming, most of which will include commercial
advertising. We generally do not intend to produce programming for our non-music
channels, and will obtain this programming from various third party content
providers. To date, we have entered into agreements for a total of 25 channels
with content providers including NPR, BBC, Bloomberg News Radio, C-SPAN, Sports
Byline USA, National Public Radio, Public Radio International, Classic Radio,
Hispanic Radio Network, World Radio Network, Wisdom Channel, Speedvision Radio
and Outdoor Life Radio.

     In connection with our music programming, we will be required to negotiate
and enter into royalty arrangements with performing rights societies, such as
the American Society of Composers, Authors and Publishers ('ASCAP'), Broadcast
Music, Inc. ('BMI') and SESAC, Inc. ('SESAC'). These organizations collect
royalties and distribute them to songwriters and music publishers. Copyright
users negotiate a fee with these organizations based on a percentage of
advertising and/or subscription revenues. If the parties cannot reach agreement
with ASCAP or BMI, special judicial rate setting procedures are available under
antitrust consent decrees that govern these organizations. SESAC is not bound by
a consent decree or a special judicial rate setting mechanism. Broadcasters
currently pay a combined total of 4% of their revenues to the music performing
rights societies. We also will be required to negotiate similar arrangements
with the owners of the copyrights in sound recordings under the Digital
Performance Right in Sound Recordings Act of 1995 (the 'Digital Recordings
Act'). The determination of some of the royalty arrangements with the owners of
sound recording copyrights under the Digital Recordings Act were previously
subject to arbitration proceedings. In 1998, the Copyright Office reviewed the
results of this arbitration and set the royalty rate at 6.5% of the licensee's
'gross revenues resulting from residential services in the United States'
including subscription fees, advertising and time share revenues. We believe
that we will be able to negotiate royalty arrangements with the music performing
rights organizations and the owners of sound recording copyrights, but we cannot
assure you as to the terms of the royalty arrangements ultimately negotiated or
established by arbitration or judicial rate setting.

                                       39

MARKETING AND DISTRIBUTION

     We plan to offer a high quality broadcast service with targeted music
formats, nearly seamless signal coverage throughout the continental United
States, commercial-free music programming and digital quality fidelity. Our
marketing strategy for CD Radio has three interrelated components: (1) creating
consumer awareness of CD Radio, (2) generating subscriptions to CD Radio and (3)
generating purchases of consumer electronic devices capable of receiving
CD Radio broadcasts.

     We believe that the introduction of CD Radio will have high news value,
which we expect will result in significant national and local publicity before
and during the initial launch of the service. In addition, we plan to engage in
extensive marketing, advertising and promotional activities to create consumer
awareness of CD Radio. This includes an ongoing major advertising campaign
funded principally by us, together with expected manufacturer and retailer
cooperative advertising. A major national umbrella campaign will utilize a full
mix of media, including network and cable television, radio, print and
billboard.

     We intend to focus our initial efforts on a number of demographic groups
that we believe represent potential target markets for CD Radio, including
commuters, niche music listeners, Hispanic listeners, sports enthusiasts, truck
drivers, recreational vehicle owners and consumers in areas with sparse radio
coverage. We also intend to aggressively target early adopters of new
technologies, who we believe are likely to have a high level of interest in
CD Radio.

     Commuters. Of the more than 100 million commuters, we have identified 34
million as highly addressable by virtue of their commute times averaging over
one hour daily. To reach these commuters, we plan to purchase radio advertising
spots on stations with frequent traffic reports, purchase outdoor billboard
advertising on long commute roads and place inserts in gasoline credit card
bills.

     Niche Music Listeners. Niche music categories, such as classical, jazz,
rap, gospel, soundtracks, oldies and children's programming, constitute
approximately 30% of the market for recorded music sales. To reach niche music
listeners, we intend to work with the recording industry to include print
material about CD Radio inside niche music compact disc packaging, place print
advertising in specialty music magazines targeted to niche music listeners and
members of fan clubs, conduct direct mailings to specialized music mailing lists
of record clubs and sponsor and advertise at certain music events.

     Hispanic Market. Currently there are approximately 30 million
Spanish-speaking Americans, many of whom have limited access to Spanish language
radio, and this population group is growing rapidly and is expected to reach 36
million by 2005. We intend to broadcast a number of music and non-music channels
that will cater to the Hispanic market. We plan to purchase local television
spots on Spanish speaking channels and place advertising in national Spanish
language magazines and local Spanish language newspapers.

     Sports Enthusiasts. Many fans of various sports are unable to receive
broadcasts of interest to them because events are broadcast only within limited
regional areas. We intend to broadcast a number of channels containing this
sports programming. We plan to purchase advertising on national and regional
cable television sports channels, in sports magazines and in the sports sections
of newspapers.

     Truck Drivers. According to the U.S. Department of Transportation, there
are approximately three million professional truck drivers in the United States,
of whom approximately 1.1 million are long-distance haulers. We intend to place
sampling displays at truck stops and to advertise in publications and on
Internet sites which cater to truck drivers.

     Recreational Vehicle Owners. There are approximately three million
recreational vehicles in the United States. We plan to advertise in magazines
targeted to recreational vehicle enthusiasts, conduct direct mailings targeted
to these individuals and place sampling displays at recreational vehicle
dealerships.

     Sparse Radio Zones. More than 45 million people aged 12 and over live in
areas with such limited radio station coverage that the areas are not monitored
by Arbitron. We believe that of

                                       40



<PAGE>

these people, approximately 22 million people receive five or fewer FM stations,
1.6 million receive only one FM station and at least one million people receive
no FM stations. To reach these consumers, we plan to utilize local newspaper and
target direct mailings to music enthusiasts in these areas.

     We expect that FM modulated receivers and three-band receivers will be sold
through electronics superstores as well as independent autosound retailers and
that radio cards will be sold through electronics superstores, mass merchants
and direct marketing channels, such as the Internet.

SUBSCRIPTION AND BILLING

     We intend to contract out our customer care functions to a national
customer service and telemarketing provider. Operators at our customer care
center will have the ability to access our separate billing services center for
various functions, including customer activation, billing inquiries, program
service changes and address changes. When appropriate, operators will also refer
technical problems to either a CD Radio help desk, or to the appropriate
equipment manufacturer. We intend to automate customer care functions where
appropriate, either through interactive voice response technology (IVR), or
through our Web site. We expect to pay our customer service provider based on
transaction and call volume.

     We also intend to contract out our customer billing and activation function
to a national billing services company. This billing center will receive
requests from our separate customer care center for actions such as radio
activations, deactivations, program service changes, and billing inquiries. This
billing center will handle all other customer processing operations, including
remittance processing, collections, interfacing to credit/debit card clearing
houses, and fulfillment processing. We expect that a large percentage of our
subscribers will pay using a credit card. However, our customer billing system
will also have the capability to do direct invoicing. There will be a modest
one-time activation fee to cover subscriber sign-up costs. The billing software
application and database will be customized to handle our unique requirements,
including interfacing and exchanging of information with automobile
manufacturers, automobile dealers and consumer electronic retailers, and
employing special techniques to address the challenge of activating and
deactivating receivers. We expect to pay our billing services company based on
transaction volumes.

THE CD RADIO DELIVERY SYSTEM

     The CD Radio satellite system is designed to provide nearly seamless signal
coverage throughout the continental United States. This means that listeners
will almost always be within the broadcast range of CD Radio, unlike current FM
radio broadcasts, which have an average range of only approximately 30 miles.
The CD Radio system is designed to provide clear reception in most areas despite
variations in terrain, buildings and other obstructions. The system is designed
to enable motorists to receive CD Radio in all outdoor locations where the
vehicle has an unobstructed line-of-sight with one of our satellites or is
within range of one of our terrestrial repeating transmitters.

     The portion of the S-band located between 2320 MHz and 2345 MHz has been
allocated by the FCC exclusively for national satellite radio broadcasts, and
will augment traditional AM and FM radio bands. This portion of the spectrum was
selected because there are virtually no other users of this frequency band in
the United States, thus minimizing potential signal interference. In addition,
this frequency band is relatively immune to weather related attenuation, which
is not the case with higher frequencies.

     We plan to use 12.5 MHz of bandwidth in the 7060-7072.5 MHz band (or some
other suitable frequency) for uplink transmissions to our satellites. Downlink
transmission from the satellites to subscribers' will use 12.5 MHz of bandwidth
in the 2320.0-2332.5 MHz frequency band.

     In May 1998, we expanded our system from 50 planned broadcast channels to
up to 100 channels. As part of that expansion, we announced our plan to change
the orbital location of our

                                       41



<PAGE>

satellites from geostationary orbits over the equator to inclined elliptical
orbits. This modification will allow our satellites to maximize the time spent
over the continental United States, which will permit us to fully utilize the
bandwidth allocated to us by the FCC. Each satellite will travel in a figure
eight pattern extending above and below the equator, and will spend
approximately 16 hours per day north of the equator. A satellite north of the
equator will serve the United States at a better elevation angle than a
geostationary satellite over the equator. At any given time, two of our three
satellites will operate from the portion of the orbit north of the equator while
the third satellite will not broadcast as it traverses the portion of the orbit
south of the equator.

     CD Radio is designed to broadcast the same signals from two of the three
satellites. This design involves new applications of technology that have not
been deployed and we cannot assure you that the CD Radio system will work as
planned.

     The CD Radio delivery system will consist of three principal components:
(1) the satellites; (2) the receivers; and (3) the National Broadcast Studio.

  THE SATELLITES

     Satellite Design. Our satellites are of the Loral FS-1300 model series.
This family of satellites has a history of reliability with a total of 275 years
in-orbit operation time. The satellites are designed to have a useful life of
approximately 15 years. To ensure the durability of our satellites, we have
selected components and subsystems that have a demonstrated track record on
operational FS-1300 satellites, such as N-STAR, INTELSAT VII and TELSTAR. In
addition, a full series of ground tests will be performed on each of our
satellites before launch to detect assembly defects and avoid premature
satellite failure.

     Our satellites will utilize a three-axis stabilized design. Each satellite
will contain an active attitude and position control subsystem; a telemetry,
command and ranging subsystem; a thermal control subsystem and an electrical
power subsystem. Power will be supplied by silicon solar arrays and, during
eclipses, by nickel-hydrogen batteries. Each satellite after deployment will be
approximately 81 feet long, 19 feet wide and 17 feet tall.

     Our satellites will incorporate a design which will act essentially as a
'bent pipe,' relaying received signals directly to the ground. Our satellites
will not contain on-board processors. All of our processing operations will be
on the ground where they are accessible for maintenance and continuing
technological upgrade without the need to launch replacement satellites.

     High Elevation Angles. We plan to place our satellites in orbits that
extend over North America to provide very high signal elevation angles and
thereby mitigate service interruptions which can result from signal blockage and
fading. Each of our two transmitting satellites will broadcast the same signal.

     Memory Buffer. Our transmission design incorporates the use of a memory
buffer chip contained within the receiver. Each memory buffer chip is designed
to store signals and to mitigate service interruptions which can result from
signal blockage and fading. As with any wireless broadcast service, we expect to
experience occasional 'dead zones' where the service from our satellites will be
interrupted by nearby tall buildings, elevations in topography, tree clusters,
highway overpasses and similar obstructions; however, in most of these places,
we expect that subscribers will continue to receive a signal from their
receiver's memory buffer.

     Terrestrial Repeaters. In some areas with high concentrations of tall
buildings, such as urban cores and in tunnels, signals from our satellites will
be blocked and reception will be adversely affected. In these urban areas, we
plan to install terrestrial repeating transmitters to rebroadcast our satellite
signals, increasing the availability of service. The FCC has not yet established
rules governing these terrestrial repeaters, and we cannot predict the outcome
of the FCC's current rulemaking on this subject. We also will need to obtain the
rights to use towers or the roofs of some structures where the repeaters will be
installed. We cannot assure you that we can obtain these tower or roof rights on
acceptable terms or in all appropriate locations.

     During 1998, we completed the construction and testing of our terrestrial
repeater network in San Francisco on an experimental basis. During 1999 and
2000, we expect to execute agreements for site acquisition, site design and site
construction services for the remainder of our terrestrial repeaters, acquire
all necessary sites and complete construction at all of these sites. In
addition, in 1999 we expect to purchase the digital broadcast equipment
necessary to operate our terrestrial repeater network.

     Satellite Construction and Launch Services. In March 2, 1993, we entered
into a contract with Loral to build three satellites, two of which we intended
to launch and one of which we intended to keep in reserve as a spare. Under the
contract, we had an option to order a fourth satellite on preset price and
delivery terms. We notified Loral of the exercise of this option in March 1998.

     On July 28, 1998, as a result of an evaluation of the advantages of a
three-satellite orbital configuration, we and Loral entered into the Loral
Satellite Contract. Under the Loral Satellite Contract, Loral has agreed to
construct, launch and deliver our three satellites, in-orbit and checked-out, to
construct for us a fourth satellite for use as a ground spare and to become our
launch services provider. Our four satellites are currently being tested or
under construction. Our first satellite has been substantially completed and is
being tested. All of the components of our second satellite are either
substantially complete or undergoing final testing before integration. All of
the subsystems for our third and fourth satellites are also under construction.

     Each of our satellites is scheduled to be launched on Proton launch
vehicles. Loral has scheduled the launch of our first satellite for January
2000, the launch of our second satellite in March 2000, the launch of our third
satellite by May 2000 and has agreed to deliver our fourth satellite to a
designated ground storage site by August 2000. Loral expects to deliver all
three of our satellites in-orbit and checked-out by June 30, 2000. We cannot
assure you that Loral will be able to meet the above schedule. It is a default
under the Loral Satellite Contract if (1) we fail to maintain a minimum net
worth, (2) we fail to have sufficient funds or committed financing to pay our
obligations on a timely basis or (3) there occurs an event of default under our
existing credit agreement with Bank of America and other lenders.

     Title to our first, second and third satellites will pass to us at the time
these satellites are delivered to us in-orbit and checked out. Risk of loss for
our first, second and third satellites will pass to us at the time of launch.
Title and risk of loss for our fourth satellite will pass to us at the time this
satellite is shipped to the ground storage site designated by us. Each satellite
is warranted to be in accordance with the performance specifications contained
in the Loral Satellite Contract and free from defects in materials and
workmanship. Loral's warranties will expire at the time of launch or, in the
case of our fourth satellite, two years from the date of delivery to the ground
storage site. If there is a delay in the construction of the satellites that is
caused by us, the Loral Satellite Contract provides that the terms of the
contract will be equitably adjusted.

     Following the launch of each satellite, Loral will conduct an in-orbit
performance verification. If this testing shows that a satellite is not meeting
the satellite performance specifications contained in the Loral Satellite
Contract, we and Loral have agreed to negotiate an equitable reduction in the
final payment to be made by us for the affected satellite.

     Satellite launches have significant risks, including destruction or damage
of the satellite during launch or failure to achieve proper orbital placement.
Although past experience is not necessarily indicative of future performance,
the Proton family of Russian-built launch vehicles has a 92% launch success rate
based on its last 50 launches. There is no assurance that the launches of our
satellites will be successful. Satellites also may fail to achieve a proper
orbit in some instances or be damaged in space. Loral will not bear the risk of
loss for either a satellite or launch vehicle failure. However, Loral will
provide a free launch if there is a failure of the first Proton launch vehicle
which is used to launch one of our satellites. In that event, we would attempt
to launch the spare satellite that we are having constructed. See 'Risk
Factors -- We are dependent upon Loral to build and launch our satellites' and
' -- Satellite launches have significant risks.'

     We are relying upon Loral to arrange for the timely launch of our
satellites. Failure by Loral to arrange to launch the satellites in a timely
manner could materially adversely affect our

                                       43



<PAGE>

business. Loral will not be liable for indirect or consequential damages or lost
revenues or profits resulting from late delivery or other defaults. If Loral
fails to deliver the three satellites in-orbit and checked out by July 31, 2000
or fails to deliver the fourth satellite to its storage site by September 30,
2000, it may be liable for specific late delivery penalties. We cannot assure
you that these remedies will adequately mitigate any damage to our business
caused by launch delays.

     After reaching agreement with Loral to provide launch services, we
terminated our prior launch services agreement with Arianespace S.A.
('Arianespace') and terminated the related vendor financing with a subsidiary of
Arianespace. As a result of these terminations, we incurred a liability of
approximately $18 million. We expensed this item, together with approximately $7
million of related capitalized and other costs, in the second quarter of 1998.

     Risk Management and Insurance. Three custom-designed, fully dedicated
satellites are required to broadcast all 100 planned channels of CD Radio. Our
agreement with Loral includes a free relaunch if there is a failure of the first
Proton launch vehicle used to launch one of our satellites. We intend to insure
against other contingencies, including a failure during launch caused by factors
other than the launch vehicle and failure of launch vehicles other than the
first Proton. If we are required to launch our spare satellite due to a launch
failure, our operational timetable could be delayed. The launch or in-orbit
failure of two satellites would require us to arrange for additional satellites
to be built and could delay the commencement or continuation of our operations
by at least 16 months. See 'Risk Factors -- We are dependent upon Loral to build
and launch our satellites' and ' -- Satellite launches have significant risks.'

     Once properly deployed and operational, the historical risk of premature
total satellite failure has been less than 1% for U.S. geosynchronous commercial
communication satellites. Before the launch of our first satellite, we intend to
purchase insurance covering launch risks and in-orbit failure during the first
two years of operation for each of our satellites. Before the expiration of this
insurance, we intend to evaluate the need for in-orbit insurance for the
remainder of the estimated useful life of each satellite. After we have launched
our satellites and begun to generate revenues, we will evaluate the need for
business interruption insurance.

     Satellites are designed to minimize the adverse effects of transmission
component failure through the incorporation of redundant components which
activate automatically or by ground command upon failure. If multiple component
failures occur, and the supply of redundant components is exhausted, the
satellite generally will continue to operate, but at reduced capacity. In that
event, signal quality may be preserved by reducing the number of channels
broadcast until a replacement satellite can be launched. Alternatively, the
number of broadcast channels may be preserved by reducing the signal quality
until a replacement satellite can be launched.

  THE RECEIVERS

     Consumers purchasing new vehicles will be able to receive CD Radio through
a new generation of three-band radios installed by Ford or another automotive
manufacturer. In addition, consumers will be able to receive CD Radio by
installing specially designed radio receivers in their existing vehicles. The
market for new radio receivers installed in existing vehicles (which is commonly
referred to as the 'aftermarket') is approximately 7 to 8 million units
annually. In the automotive aftermarket, we expect that CD Radio subscribers
will initially have the choice of one of three different receiving devices for
their cars -- an FM modulated receiver, a three-band receiver and a radio card.
These devices, along with CD Radio satellite antennas, are expected to be
manufactured and distributed by a number of consumer electronics manufacturers.
To date, we have entered into agreements with Delco, Recoton, Alpine and
Panasonic to design and develop CD Radio receivers. All CD Radio receivers will
have a visual display that will indicate the channel and format selected, as
well as the title, recording artist and album title of the musical selection
being played. Although we do not intend to manufacture or distribute FM
modulated receivers, three-band receivers, radio cards or antennas, in the early
years of our service their availability will be critical to us because they will
be the only means by which to receive CD Radio.

                                       44



<PAGE>

     These three CD Radio receivers will offer customers a range of options in
price, ease-of-installation and quality.

     FM Modulated Receivers. The CD Radio FM modulated receiver will be usable
in all vehicles which have an FM radio, or approximately 95% of all U.S.
vehicles. Each FM modulated receiver will operate with a device that will be
approximately the size of a 35mm camera, and will be mounted either in the
vehicle's trunk, behind the dashboard or under a seat. Each FM modulated
receiver will interface with a vehicle's existing radio through the FM antenna
input. The CD Radio data display, as well as the controls for changing channels,
will be contained in a small remote control which will either be wired or
wireless. We expect the retail price of this FM modulated receiver, with a
hard-wired satellite antenna and professional installation, will be
approximately $299. We anticipate that FM modulated receivers will be sold
through electronics superstores as well as independent autosound retailers.

     FM modulation technology is widely used in the autosound industry for the
integration of automobile compact disc changers, which typically interface with
the player unit through the FM antenna input and, like the CD Radio FM modulated
receiver, are controlled through a remote control. Approximately 700,000 FM
modulated compact disc changers were sold in the United States in 1998.

     Three-Band Receivers. To address consumers who replace their vehicle's
sound system, we expect there will be available a receiver capable of receiving
AM, FM and CD Radio broadcasts. In appearance, this three-band receiver will be
nearly identical to existing aftermarket car stereos and will permit the user to
listen to AM, FM or CD Radio with the push of a button. Like existing
conventional radios, a number of these three-band receivers may also incorporate
cassette or compact disc players. The receiver apparatus will include a
'CD Radio Ready' head-unit, which will accept the direct output of the CD Radio
outboard receiver device. We expect the retail price of these CD Radio-ready
receivers, including the receiver device, antenna and professional installation,
will be approximately $150 more than similar receivers that are not capable of
receiving CD Radio broadcasts. We anticipate that three-band receivers,
including the head unit and the receiver device, will be sold through electronic
superstores as well as independent autosound retailers. Our long-term objective
is to promote the adoption of three-band receivers as standard equipment in all
automobiles sold in the United States.

     Radio Cards. CD Radio's wireless adapter, or radio card, will not require
professional installation and will be usable by all vehicles in the United
States equipped with a cassette player, which represents approximately 65% of
all vehicles on the road. Each radio card will include two components -- the
radio card adapter, which will insert into existing cassette slots, and a
wireless version of the CD Radio satellite antenna. We expect the retail price
of the radio card, including the wireless satellite antenna, will be
approximately $199. The radio card will be sold though electronics superstores,
mass merchant type stores and direct marketing channels, such as the Internet.

     Lucent Agreement. On April 28, 1998, we entered into an agreement with
Lucent to design the overall architecture of the CD Radio system and to develop
and manufacture a custom designed chip set for use in CD Radio receivers and, on
February 2, 1999, we amended and restated this agreement. We have agreed to pay
Lucent the cost of the development work related to the chip sets, currently
estimated to be approximately $27 million. Approximately half of the expected
payments to Lucent are dependent upon satisfactory completion of designated
development milestones. Lucent has completed design of the system architecture
and delivered the chip set specification on schedule at the end of August.
However, we cannot assure you that Lucent will be able to deliver chip sets
within the time frame described in our agreement. In addition, the cost to us of
the chip set development work could exceed $27 million.

     Lucent has agreed to repay all the costs of the chip set development work,
through discounted chip set prices, after commercial production of the chip set
has begun.

     Delco Agreement. On March 29, 1999, we entered into an agreement with Delco
to design, develop and manufacture three-band receivers (including the related
receiver device) and satellite

                                       45



<PAGE>

antennas for sale to major automotive manufacturers. Delco is the world's
largest producer of audio systems for original automotive equipment and is a
leader in mobile communications technology. We have agreed to pay Delco, when
specified development milestones are completed, specific costs relating to
designing and manufacturing prototypes of this three-band receiver and antenna.
Delco has agreed to use commercially reasonable efforts to complete the design
and development work and have three-band receivers and antennas available for
sale to automobile manufacturers by March 2001. We cannot assure you that Delco
will be able to design and develop these three-band receivers and antennas. In
addition, although we expect that Delco will manufacture and sell substantial
quantities of three-band receivers and antennas, Delco is not required to
manufacture specified quantities under this agreement.

     Recoton Agreement. On February 23, 1999, we entered into an agreement with
Recoton to design and develop specifications for the FM modulated receiver
(including the receiver device) and the radio card, and manufacture prototypes
of each. Recoton, the owner of the Jensen, Advent, AR/Acoustic Research and
Interact brands, is a worldwide manufacturer and distributer of consumer
electronic products, and is the third largest producer of aftermarket car
stereos sold in the U.S. As part of this agreement, we also agreed to deliver to
Recoton plans and specifications for a hard-wired satellite antenna, which we
have separately developed. Recoton has agreed to manufacture prototypes of this
hard-wired satellite antenna for use with FM modulated receivers and to use
commercially reasonable efforts to design and develop a wireless satellite
antenna for use with radio cards. We have agreed to pay Recoton, when specified
development milestones are completed, specific costs relating to designing and
manufacturing prototypes of the FM modulated receiver, the radio card, the
hard-wired satellite antenna and the wireless satellite antenna. Recoton has
agreed to deliver to us plans and specifications for the FM modulated receiver,
the radio card and the wireless satellite antenna within 90 business days after
Lucent delivers to us plans and specifications for the chip set. Similarly,
Recoton has agreed to deliver to us prototypes of the FM modulated receiver, the
radio card, the hard-wired satellite antenna and the wireless satellite antenna
within 90 business days after Lucent delivers to us prototypes of the chip set.
We cannot assure you that Recoton will be able to design and develop the FM
modulated receiver, the radio card or the wireless satellite antenna or that
Recoton will be able to manufacture prototypes of the FM modulated receiver, the
radio card, the hard-wired satellite antenna or the wireless satellite antenna.

     As part of our agreement with Recoton, Recoton has also agreed to negotiate
with us in good faith an agreement to manufacture, market and sell substantial
quantities of FM modulated receivers, radio cards, three-band receivers,
hard-wired satellite antennas and wireless satellite antennas which are capable
of receiving CD Radio broadcasts using Recoton's distribution network and under
our brand name. These negotiations with Recoton are in an early stage and we
cannot assure you that we will be able to complete a manufacturing and marketing
agreement with Recoton. Recoton has one of the largest distribution systems for
automotive consumer electronics with more than 1,000 retail customers, which
Recoton believes have more than 30,000 outlets in the United States and Canada.

     Alpine Agreement. On July 12, 1999, we entered into an agreement with
Alpine to design and develop three-band receivers with antennas. Alpine is a
leading manufacturer of high performance mobile electronics. We have agreed to
pay Alpine incentive payments for completing three milestones for delivery of
prototype receivers, including the presentation of a functioning CD Radio
receiver by January 2001. We cannot assure you that Alpine will be able to
design and develop these three-band receivers with antennas or that Alpine will
meet any anticipated milestone dates. In addition, Alpine is not required to
manufacture specified quantities of receivers under this agreement.

     Panasonic Agreement. On July 22, 1999, we entered into an agreement with
Matsushita Communication Industrial Corporation of USA ('Panasonic'), a
subsidiary of Matsushita, to design and develop three-band receivers with
antennas. Matsushita is the world's largest consumer electronics company and the
maker of Panasonic products. We have agreed to pay Panasonic incentive payments
for completing three milestones for delivery of prototype receivers. We cannot

                                       46



<PAGE>

assure you that Panasonic will be able to design and develop these three-band
receivers with antennas or that Panasonic will meet any targeted milestone
dates. In addition, Panasonic is not required to manufacture specified
quantities of receivers under this agreement.

     None of the CD Radio receivers or antennas is currently available and,
other than Delco, Recoton, Alpine, Panasonic and Visteon (a unit of Ford), we
are not aware of any manufacturer currently developing these products. We have
commenced discussions with several other manufacturers regarding manufacturing
receivers and antennas for retail sale in the United States. We cannot assure
you that these discussions will result in a binding commitment by any
manufacturer to produce receivers and antennas in a timely manner so as to
permit the widespread introduction of CD Radio in accordance with our business
plan or that sufficient quantities of receivers and antennas will be available
to meet anticipated consumer demand. Failure to have at least one manufacturer
develop and widely market receivers and antennas at affordable prices, or to
develop and widely market these products upon the launch of CD Radio, would have
a material adverse effect on our business. In addition, our FCC license depends
on us certifying that our system includes a receiver design that will permit end
users to access the system of the other licensee.

     In addition to our agreement with Ford, we are currently in discussions
with several other automobile manufacturers to include CD Radio reception
capability either as standard or optional equipment in new cars. We do not
expect CD Radio reception capability to be included in new vehicles before the
fourth quarter of 2000. Our long-term objective is to promote the adoption of
three-band radios as standard equipment in all automobiles sold in the United
States.

     To reduce fraud, each CD Radio receiver will contain a security circuit
with an electronically encoded identification number. After verification of
subscriber billing information, we will transmit a digital signal to activate
the receiver's CD Radio capability. This feature will help us protect against
piracy of CD Radio's broadcasts. Through this feature, we will directly (via
satellite) deactivate receivers of subscribers who are delinquent in paying the
monthly subscription fee.

THE NATIONAL BROADCAST STUDIO

     We will originate our programming from our National Broadcast Studio in
Rockefeller Center in New York City. The National Broadcast Studio will house
our corporate headquarters, our music library, facilities for programming
origination, programming personnel and program hosts, and facilities to transmit
programming to our orbiting satellites, to activate or deactivate service to
subscribers and to perform the tracking, telemetry and control of the
satellites.

     Programming will be originated at the National Broadcast Studio and
transmitted to our satellites for broadcast to CD Radio subscribers. We expect
that our broadcast transmissions will be uplinked to our satellites at
frequencies in the 7060-7072.5 MHz band. The satellites will receive and convert
the signal to the 2320.0-2332.5 MHz band. The satellites then will broadcast the
signal to the United States, at a power level sufficient to enable its receipt
directly by subscribers. Service-related commands also will be relayed from the
National Broadcast Studio to our satellites for retransmission to subscribers'
receivers. These service-related commands include those required to
(1) initiate and suspend subscriber service, (2) change the encryption
parameters in receivers to reduce piracy and (3) activate receiver displays to
show program related information.

     Tracking, telemetry and control of our orbiting satellites also will be
performed from the National Broadcast Studio. These activities will include
routine stationkeeping, such as satellite orbital adjustments and monitoring of
the satellites. Loral Skynet, a division of Loral, is designing, developing,
integrating, installing and testing our tracking, telemetry and command
facilities. Loral Skynet also will provide back-up tracking, telemetry and
command capabilities from its facility in Vernon, New Jersey. As part of our
tracking, telemetry and command facilities, Loral Skynet is constructing for us
two earth stations in Quito, Ecuador, and Utibe, Panama. These earth stations,
which will be operated by Loral Skynet, will permit us to continuously
communicate with our satellites.

                                       47

DEMONSTRATIONS OF THE CD RADIO SYSTEM

     In support of our application for our FCC license, we conducted a
demonstration of our proposed radio service from November 1993 through November
1994. The demonstration involved the transmission of S-band signals to a
prototype S-band radio and satellite dish antenna installed in a car to simulate
some of the transmission characteristics of our planned system. Because there
are no commercial satellites in orbit capable of transmitting S-band frequencies
to the United States, we constructed a terrestrial simulation of our planned
system. For this purpose, we selected a test range covering several kilometers
near Washington, D.C. which included areas shadowed by buildings, trees and
overpasses. We placed S-band transmitters on the rooftops of a number of tall
buildings in such a way as to simulate the signal power and angle of arrival of
satellite transmissions to be used for our proposed service. We also modified
the standard factory installed sound system of an automobile to create a radio
receiving AM, FM and S-band signals, and integrated our satellite dish antenna
into the car roof. The demonstrations included the reception of 30 channels of
compact disc quality stereo music by the prototype radio while the car was
driven throughout the test range. We have also successfully tested our system in
San Francisco, where construction of our terrestrial repeater network has been
completed. Before testing with orbiting satellites, antennas and receivers
suitable for commercial production, we cannot assure you that the CD Radio
system will function as intended. See 'Risk Factors -- Our planned system relies
on unproven applications of technology.'

COMPETITION

     We expect to face competition from two principal sources: (1) conventional
AM/FM radio broadcasting, including, when available, terrestrial digital radio
broadcasting; and (2) XM, the other holder of an FCC license to provide a
satellite-based digital audio radio service. XM recently announced that it had
entered into an exclusive agreement with General Motors Corporation, which has a
significant equity interest in XM's parent company, under which GM would install
devices capable of receiving XM's signal beginning in 2001. In addition, XM has
obtained substantial financing from GM, Hughes Electronics Corporation (a GM
subsidiary) and several other investors.

     The AM/FM radio broadcasting industry is very competitive. Radio stations
compete for listeners and advertising revenues directly with other radio
stations within their markets on the basis of a variety of factors, including
program content, on-air talent, transmitter power, assigned frequency, audience
characteristics, local program acceptance and the number and characteristics of
other radio stations in the market. Many of our radio broadcasting competitors
have substantially greater financial resources than we do.

     Unlike CD Radio, the radio industry has a well established market for its
services and generally offers 'free' broadcast reception paid for by commercial
advertising rather than by a subscription fee. In addition, some AM and FM
stations, such as National Public Radio, offer programming without commercial
interruption. Many radio stations also offer information programming of a local
nature, such as local news or traffic reports, which we may be unable to offer.
CD Radio will compete with conventional radio stations on the basis of its
targeted programming formats, nearly seamless signal coverage, freedom from
advertising and digital quality sound, features which are largely unavailable on
conventional broadcast radio.

     Currently, radio stations broadcast by means of analog signals, as opposed
to digital transmission. We believe, however, that within several years,
terrestrial broadcasters may be able to place digital audio broadcasts into the
bandwidth occupied by current AM and FM stations and simultaneously transmit
both analog and digital signals on the AM and FM bands. The limited bandwidth
assigned to AM stations will result in lower quality digital signals than can be
broadcast by FM stations. As a result, we expect that the use of this technology
will permit digital AM sound quality to approach monaural FM sound quality and
permit digital FM broadcasts to approach compact disc sound quality. To receive
these digital AM/FM broadcasts, listeners will need to purchase new digital
radios which currently are not commercially available. While the development of
digital broadcasting would eliminate one of the advantages of CD Radio over FM

                                       48



<PAGE>

radio, we do not believe it would affect broadcasters' ability to address the
other advantages of CD Radio. In addition, we view the growth of terrestrial
digital broadcasting as a positive force that would encourage listeners to
replace existing radios and thereby facilitate the introduction of receivers
capable of receiving CD Radio broadcasts.

     Although some existing satellite operators currently provide music
programming to customers at fixed locations, these operators are incapable of
providing CD Radio-type service to vehicles as a result of some or all of the
following reasons: (1) these operators do not broadcast on radio frequencies
suitable for reception in a mobile environment; (2) CD Radio-type service
requires fully dedicated satellites; (3) CD Radio-type service requires a custom
satellite system design; and (4) CD Radio-type service requires regulatory
approvals, which existing satellite operators do not have.

     The FCC could also grant new licenses that would enable additional
competitors to broadcast satellite radio. Finally, there are many portions of
the electromagnetic spectrum that are currently licensed for other uses and some
other portions for which licenses have been granted by the FCC without
restriction as to use, and we cannot assure you that these portions of the
spectrum could not be utilized for satellite radio broadcasting in the future.
Although any of these licensees would face cost and competition barriers, we
cannot assure you that there will not be an increase in the number of
competitors in the satellite radio industry.

TECHNOLOGY AND PATENTS

     We have been granted U.S. patents on various features of satellite radio
technology. We cannot assure you, however, that any U.S. patent issued to us
will cover our actual commercialized technology or will not be circumvented by
others, or that if challenged would be held to be valid. We have filed patent
applications covering CD Radio system technology in Argentina, Australia,
Brazil, Canada, China, France, Germany, India, Italy, Japan, South Korea,
Mexico, the Netherlands, Spain, Switzerland and the United Kingdom, and been
granted patents in a number of these countries. We cannot assure you that
additional foreign patents will be awarded to us or, if any of these patents are
granted, that the laws of foreign countries where we receive patents will
protect our proprietary rights to our technology to the same extent as the laws
of the United States. Although we believe that obtaining patent protection may
provide benefits, we do not believe that our business is dependent on obtaining
patent protection or successfully defending any of the patents that may be
obtained against infringement by others.

     Some of our know-how and technology is not the subject of U.S. patents. To
protect our rights, we require some of our employees, consultants, advisors and
collaborators to enter into confidentiality agreements. We cannot assure you,
however, that these agreements will provide meaningful protection for our trade
secrets, know-how or other proprietary information if there is any unauthorized
use or disclosure. In addition, our business may be adversely affected by
competitors who independently develop competing technologies.

     Our proprietary technology was principally developed by Robert D. Briskman,
CD Radio's co-founder, and was assigned and belongs to us. We believe that we
are the sole owner of the technology covered by our issued patents. We cannot
assure you, however, that third parties will not bring suit against us for
patent infringement or for declaratory judgment to have our patents declared
invalid. On January 12, 1999, we filed a lawsuit against XM in the United States
District Court for the Southern District of New York. The lawsuit alleges patent
infringement by XM of our U.S. Patent Nos. 5,319,673, 5,485,485 and 5,592,471.
The court has since entered a scheduling order, and the parties have begun
document production and discovery. We expect the trial to begin in January of
2001. See ' -- Legal Proceedings.'

     If a dispute arises concerning our patents, trade secrets or know-how,
litigation might be necessary to enforce our patents, to protect our trade
secrets or know-how or litigation may occur to determine the scope of the
proprietary rights of others. This litigation could result in substantial cost
to, and diversion of effort by, us, and adverse findings in any proceeding could
subject us to

                                       49



<PAGE>

significant liabilities to third parties, require us to seek licenses from third
parties or otherwise adversely affect our ability to successfully develop and
market CD Radio.

GOVERNMENT REGULATION

     As an operator of a privately owned satellite system, we are regulated by
the FCC under the Communications Act. The FCC is the government agency with
primary authority in the United States over satellite radio communications. We
currently must comply with regulation by the FCC principally with respect to
(1) the licensing of our satellite system; (2) preventing interference with or
to other users of radio frequencies; and (3) compliance with rules that the FCC
has established specifically for United States satellites and rules that the FCC
has established for providing a satellite radio service.

     On May 18, 1990, we proposed that the FCC establish a satellite radio
service and applied for an FCC license. On March 3, 1997, the FCC adopted rules
for the national satellite radio broadcast service (the 'FCC Licensing Rules').
Pursuant to the FCC Licensing Rules, an auction was held among the applicants on
April 1 and 2, 1997. We were a winning bidder for one of two FCC licenses with a
bid of approximately $83 million. XM was the other winning bidder for an FCC
license with a bid of $89 million. After payment of the full amount by us, on
October 10, 1997, the FCC's International Bureau issued us a license to place
two satellites in a geostationary orbit. Our FCC license was effective
immediately; however, for a period of 30 days following the grant of the FCC
license, those parties that had filed comments or petitions to deny in
connection with our application for an FCC license were entitled to petition the
International Bureau to reconsider its decision to grant the FCC license to us
or request review of the decision by the full FCC. An application for review by
the FCC was filed by one of the low-bidding applicants in the auction. This
petition requests, among other things, that the FCC adopt restrictions on
foreign ownership, which were not applied in the license issued to us by the
FCC's International Bureau on October 10, 1997 (the 'IB Order'), and, on the
basis of our ownership, overrule the IB Order. Since December 1997, there have
been no further developments concerning this petition.

     Although we believe the FCC will uphold the IB Order, we cannot predict the
ultimate outcome of any proceedings relating to this petition or any other
proceeding that may be filed. If this petition is denied, the complaining party
may file an appeal with the U.S. Court of Appeals which must find that the
decision of the FCC was not supported by substantial evidence, or was arbitrary,
capricious or unlawful to overturn the grant of our FCC license.

     Under the FCC Licensing Rules, we are required to meet specific progress
milestones. We are required to begin satellite construction within one year of
the grant of our FCC license; to launch and begin operating our first satellite
within four years; and to begin operating our entire system within six years.
The IB Order states that failure to meet these milestones will render our FCC
license null and void. On May 6, 1997, we notified the FCC that we had begun
construction on the first of our satellites. On March 27, 1997, a third party
requested reconsideration of the FCC Licensing Rules, seeking, among other
things, that the time period allotted for these milestones be shortened. To
date, the FCC has not responded to the petition for reconsideration. We cannot
predict the outcome of this petition.

     In 1998, we decided to increase the number of satellites in our system from
two to three and modify our orbits from geostationary to inclined, elliptical
geosynchronous, requiring modification of our FCC license. On December 11, 1998,
we filed an application with the FCC for this modification. Although we believe
that the FCC will approve our application for this change, we cannot assure you
that this will occur. XM and WCS Radio Inc. have filed comments opposing our
application with the FCC. The FCC staff has requested additional materials from
us, and we are in the process of complying with the staff's request. We cannot
predict the time it will take the FCC to act on our application or any of those
objections, or whether additional submissions or waiver requests will be
necessary, and we cannot be sure that the modification we have requested will be
granted. Failure of the FCC to approve the requested modification to our license
in a timely fashion would have a material adverse effect on our business,
financial condition and prospects.

     The term of our FCC license for each satellite is eight years, commencing
from the time each satellite is declared operational after having been inserted
into orbit. Upon the expiration of the term with respect to each satellite, we
will be required to apply for a renewal of the relevant FCC license. Although we
anticipate that, absent significant misconduct on our part, the FCC licenses
will be renewed in due course to permit operation of our satellites for their
useful lives, and that a license would be granted for any replacement
satellites, we cannot assure you of this renewal or grant.

     The spectrum allocated by the FCC for satellite radio in the United States
is used in Canada and Mexico for terrestrial microwave links, mobile telemetry
and other purposes. In September 1998, the United States government and Canada
reached an agreement to coordinate the use of this spectrum. Under the rules
adopted by the FCC on March 3, 1997 for the national satellite radio broadcast
service, the United States government must still coordinate the United States'
use of this spectrum with the Mexican government before our satellites may
become operational. The FCC Licensing Rules require that both ourselves and XM
successfully complete detailed frequency coordination with existing operations
in Mexico, and the IB Order conditions our FCC license on this coordination.
Although the United States government has begun this coordination process with
Mexico, we cannot assure you that we will be able to coordinate the use of this
spectrum with Mexican operators or will be able to do so in a timely manner.

     To operate our satellites, we also will have to obtain a license from the
FCC to operate our uplink facility. Normally, this approval is sought after
issuance of an FCC license. Although we cannot assure you that these licenses
will be granted, we do not expect difficulties in obtaining a feeder link
frequency and ground station approval in the ordinary course.

     In the future, any assignments or transfers of control of our FCC license
must be approved by the FCC. We cannot assure you that the FCC would approve any
of these transfers or assignments.

     The CD Radio system is designed to permit CD Radio to be received by
motorists in all outdoor locations where the vehicle has an unobstructed
line-of-sight with one of our satellites. In some areas with high concentrations
of tall buildings, such as urban cores, or in tunnels, signals from our
satellites will be blocked and reception will be adversely affected. In these
cases, we plan to install terrestrial repeating transmitters to broadcast
CD Radio. The FCC has not yet established rules governing the application
procedure for obtaining authorizations to construct and operate terrestrial
repeating transmitters. A rulemaking on the subject was initiated by the FCC on
March 3, 1997. The deadline for the public to file comments was June 13, 1997
and the deadline for filing reply comments was June 27, 1997. Several comments
were received by the FCC that sought to cause the FCC to consider placing
restrictions on our ability to deploy our terrestrial repeating transmitters.
The repeaters we have constructed in San Francisco are operating under temporary
experimental licenses. We cannot predict the outcome, or the timing of, these
FCC proceedings. In addition, in connection with the installation and operation
of our terrestrial repeating transmitters, we need to obtain the rights to use
towers or the roofs of some structures where the transmitters will be installed.
We cannot assure you that we can obtain these tower or roof rights on acceptable
terms or in appropriate locations for the operation of CD Radio.

     The IB Order conditions our FCC license on us certifying that our system
includes a receiver design that will permit end users to access XM's system. We
have made progress towards developing a receiver which is interoperable with the
satellite digital audio radio system XM is constructing. However, because of the
various technological challenges involved in designing an interoperable
receiver, we cannot predict whether we will be able to satisfy this
interoperability requirement. Complying with this interoperability requirement
could make the devices capable of receiving CD Radio broadcasts and the related
antenna more difficult and costly to manufacture. Accordingly, this
interoperability requirement could delay the commercial introduction of these
products or require that they be sold at higher prices.

     The FCC has proposed to update regulations for a new type of lighting
device that may generate radio energy in the part of the spectrum to be used by
us. The devices would be required to comply with FCC rules that prohibit these
devices from causing harmful interference

                                       51



<PAGE>

to an authorized radio service such as CD Radio. However, unless the FCC adopts
adequate technical standards specifically applicable to these devices, it may be
difficult for us to enforce our rights if the use of these devices were to
become commonplace. We believe that the currently proposed FCC rules must be
strengthened to assure protection of our spectrum. The FCC's failure to adopt
adequate standards could have a material adverse effect on reception of our
broadcasts. We believe that the FCC will set adequate standards to prevent
harmful interference, although we cannot assure you that it will do so.

     Our business operations as currently contemplated may require a variety of
permits, licenses and authorizations from governmental authorities other than
the FCC, but we have not identified any permit, license or authorization that we
believe could not be obtained in the ordinary course of business.

     The Communications Act prohibits the issuance of a license to a foreign
government or a representative of a foreign government, and contains limitations
on the ownership of common carrier, broadcast and some other radio licenses by
non-U.S. citizens. We are regulated as a private carrier, not a common carrier,
by the FCC. As such, the IB Order determined that we are not bound by the
foreign ownership provisions of the Communications Act. The FCC has before it a
petition to apply the foreign ownership rules to digital audio radio services,
but has not acted on that petition or indicated that it is likely to do so in
the near future. As a private carrier, we are free to set our own prices and
serve customers according to our own business judgment, without economic
regulation.

     The foregoing discussion reflects the application of current communications
law, FCC regulations and international agreements to our proposed service in the
United States. Changes in law, regulations or international agreements relating
to communications policy or to matters affecting specifically the services
proposed by us could adversely affect our ability to retain our FCC license and
obtain or retain other approvals required to provide CD Radio or the manner in
which our proposed service would be regulated. Further, actions of the FCC may
be reviewed by federal courts and we cannot assure you that if challenged, these
actions would be upheld.

PERSONNEL

     As of October 8, 1999, we had 77 employees and 21 part time consultants. By
commencement of operations, we expect to have approximately 150 employees. The
extent and timing of the increase in staffing will depend on the availability of
qualified personnel and other developments in our business. None of our
employees is represented by a labor union, and we believe that our relationship
with our employees is satisfactory.

LEGAL PROCEEDINGS

     On January 12, 1999, we filed a lawsuit against XM in the United States
District Court for the Southern District of New York. The lawsuit alleges patent
infringement by XM of our U.S. Patent Nos. 5,319,673, 5,485,485 and 5,592,471.
We are seeking, among other things, an injunction against infringement by XM by
any manufacture, use, offer for sale or sale within the scope of any claim of
U.S. Patents Nos. 5,319,673, 5,485,485 and 5,592,471. On March 1, 1999, XM
answered our complaint in this lawsuit, denying our allegations and asserting
affirmative defenses. The court has since entered a scheduling order, and the
parties have begun document production and discovery. We expect the trial to
begin in January of 2001. While we believe that we should prevail in this
lawsuit, we cannot assure you that the Court will rule in our favor.

     Except as described above, we are not a party to any material litigation.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Mr. Gilberti, a director, is of counsel to the law firm of Reed Smith
Shaw & McClay LLP and has provided legal services to us since 1992.

     Under an agreement dated October 21, 1992, we retained Batchelder &
Partners, Inc. ('Batchelder') to provide financial consulting services. We
agreed to terminate the agreement with Batchelder on November 30, 1997; however,
the parties agreed that the termination would not affect our obligations with
respect to some transactions entered into within 24 months of the termination
date. In January 1997, Mr. Whitworth became a partner in Batchelder. In the
fiscal year ended December 31, 1998, Mr. Whitworth, as a partner in Batchelder,
received $205,149 from the total fees we paid to Batchelder. We provided options
to purchase our shares of common stock to Batchelder and on December 29, 1997,
Mr. Whitworth received a portion of these as an option to purchase 17,800 shares
of our common stock at an exercise price of $6.25. This option is exercisable
for a period of 10 years from the date of grant. In connection with the sale in
May 1999 of the units consisting of the initial notes and warrants, we paid
Batchelder a fee of $2,000,000 and Mr. Whitworth received 9.44% of this amount.

 (1) This table is based upon information supplied by directors, officers and
     principal stockholders. Percentage of ownership is based on shares of
     common stock outstanding on October 14, 1999. Unless otherwise indicated,
     the address of the beneficial owner is that of CD Radio.

 (2) Determined as provided by Rule 13d-3 under the Exchange Act. Under this
     rule, a person is deemed to be the beneficial owner of securities that can
     be acquired by this person within 60 days from the date of determination
     upon the exercise of options, and each beneficial owner's percentage
     ownership is determined by assuming that options that are held by this
     person (but not those held by any other person) and that are exercisable
     within 60 days from the date of determination have been exercised.

 (3) Includes 793 shares of common stock acquired under CD Radio's 401(k) Plan
     and 1,540,000 shares of common stock issuable under stock options that are
     exercisable within 60 days. Under a voting trust agreement (the 'Voting
     Trust Agreement') entered into by Darlene Friedland, as grantor, David
     Margolese, as trustee, and CD Radio, Mr. Margolese has the power to vote in
     his discretion all shares of common stock owned or acquired in the future
     by Darlene Friedland and some of her affiliates (2,834,500 shares as of
     May 31, 1999) until November 20, 2002. Does not include 960,000 shares
     issuable under stock options that are not exercisable within 60 days.

 (4) Represents 1,350,000 shares of 9.2% Series A Junior Cumulative Convertible
     Preferred Stock and 650,000 shares of 9.2% Series B Junior Cumulative
     Convertible Preferred Stock which entitle the holder to vote as if the
     shares had been converted to common stock. Each share of 9.2% Series A
     Junior Cumulative Convertible Preferred Stock and 9.2% Series B Junior
     Cumulative Convertible Preferred Stock is entitled to three and one-third
     votes per share. This information is based upon Amendment No. 1 to the

     issuable upon conversion of 442,545 shares of Series C Preferred Stock and
     1,124,288 shares of common stock issuable upon the conversion of
     convertible subordinated notes which we believe were purchased in the
     public offering of these notes. This information is based upon the Schedule

VOTING TRUST AGREEMENT

     We are party to a Voting Trust Agreement by and among Darlene Friedland, as
grantor, and David Margolese, as the voting trustee. The following is a summary
of the material provisions of the Voting Trust Agreement. The complete text of
the Voting Trust Agreement is filed with the Commission as an exhibit to the
registration statement covering the exchange notes.

     The Voting Trust Agreement provides for the establishment of a trust (the
'Trust') into which there were deposited all of the shares of Common Stock owned
by Mrs. Friedland on August 26, 1997 and into which any shares of Common Stock
acquired by Mrs. Friedland, her spouse Robert Friedland, any member of either of
their immediate families or any entity directly or indirectly controlled by Mrs.
Friedland, her spouse or any member of their immediate families (the 'Friedland
Affiliates') between August 26, 1997 and the termination of the Trust must also
be deposited. The Trust will terminate on November 26, 2002.

     The Voting Trust Agreement does not restrict the ability of Mrs. Friedland
or any of the Friedland Affiliates to sell, assign, transfer or pledge any of
the shares of Common Stock

                                       57



<PAGE>

deposited into the Trust, nor does it prohibit Mrs. Friedland or the Friedland
Affiliates from purchasing additional shares of Common Stock, provided those
shares are deposited in the Trust, as described above.

     Under the Voting Trust Agreement, the trustee has the power to vote shares
of Common Stock held in the Trust in relation to any matter upon which the
holders of these shares of Common Stock would have a right to vote, including
without limitation the election of directors. For so long as David Margolese
remains trustee of the Trust, he may exercise these voting rights in his
discretion. Any successor trustee or trustees of the Trust must vote as follows:

      on the election of directors, the trustee(s) must vote the entire number
      of shares of Common Stock held by the Trust, with the number of shares of
      Common Stock voted for each director (or nominee for director) determined
      by multiplying the total number of votes held by the Trust by a fraction,
      the numerator of which is the number of votes cast for this director by
      our other stockholders and the denominator of which is the sum of the
      total number of votes represented by all shares casting any votes in the
      election of directors;

      if the matter under Delaware law or our Amended and Restated Certificate
      of Incorporation or our Amended and Restated Bylaws of CD Radio requires
      at least an absolute majority of all outstanding shares of Common Stock of
      CD Radio to be approved, the trustee(s) must vote all of the shares of
      Common Stock in the Trust in the same manner as the majority of all votes
      that are cast for or against the matter by all other stockholders of CD
      Radio; and

      on all other matters, including without limitation any amendment of the
      Voting Trust Agreement for which a stockholder vote is required, the
      trustee(s) must vote all of the shares in the Trust for or against the
      matter in the same manner as all votes that are cast for or against the
      matter by all other stockholders of CD Radio.

     The Voting Trust Agreement may not be amended without the prior written
consent, acting by unanimous vote of the Board of Directors, and approval of our
stockholders, acting by the affirmative vote of two-thirds of our total voting
power, except in limited circumstances where amendments to the Voting Trust
Agreement must comply with applicable law.

                               THE EXCHANGE OFFER

TERMS OF THE EXCHANGE OFFER

     We are offering to exchange our exchange notes for a like aggregate
principal amount of our initial notes.

     The exchange notes that we propose to issue in this exchange offer will be
substantially identical to our initial notes except that, unlike our initial
notes, the exchange notes will have no transfer restrictions or registration
rights. You should read the description of the exchange notes in the section in
this prospectus entitled 'Description of the Notes.'

     We reserve the right in our sole discretion to purchase or make offers for
any initial notes that remain outstanding following the expiration or
termination of this exchange offer and, to the extent permitted by applicable
law, to purchase initial notes in the open market or privately negotiated
transactions, one or more additional tender or exchange offers or otherwise. The
terms and prices of these purchases or offers could differ significantly from
the terms of this exchange offer. In addition, nothing in this exchange offer
will prevent us from exercising our right to discharge our obligations on the
initial notes by depositing certain securities with the trustee and otherwise.

EXPIRATION DATE; EXTENSIONS; AMENDMENTS; TERMINATION

     This exchange offer will expire at 5:00 p.m., New York City time, on
November 12, 1999, unless we extend it in our reasonable discretion. The
expiration date of this exchange offer will be at least 20 business days after
the commencement of the exchange offer in accordance with Rule 14e-1(a) under
the Exchange Act.

     We expressly reserve the right to delay acceptance of any initial notes,
extend or terminate this exchange offer and not accept any initial notes that we
have not previously accepted if any of the conditions described below under
' -- Conditions to the Exchange Offer' have not been satisfied or waived by us.
We will notify the exchange agent of any extension by oral notice promptly
confirmed in writing or by written notice. We will also notify the holders of
the initial notes by mailing an announcement or by a press release or other
public announcement communicated before 9:00 a.m., New York City time, on the
next business day after the previously scheduled expiration date unless
applicable laws require us to do otherwise.

     We also expressly reserve the right to amend the terms of this exchange
offer in any manner. If we make any material change, we will promptly disclose
this change in a manner reasonably calculated to inform the holders of our
initial notes of the change including providing public announcement or giving
oral or written notice to these holders. A material change in the terms of this
exchange offer could include a change in the timing of the exchange offer, a
change in the exchange agent and other similar changes in the terms of this
exchange offer. If we make any material change to this exchange offer, we will
disclose this change by means of a post-effective amendment to the registration
statement which includes this prospectus and will distribute an amended or
supplemented prospectus to each registered holder of initial notes. In addition,
we will extend this exchange offer for an additional five to ten business days
as required by the Exchange Act, depending on the significance of the amendment,
if the exchange offer would otherwise expire during that period. We will
promptly notify the exchange agent by oral notice, promptly confirmed in
writing, or written notice of any delay in acceptance, extension, termination or
amendment of this exchange offer.

PROCEDURES FOR TENDERING INITIAL NOTES

PROPER EXECUTION AND DELIVERY OF LETTERS OF TRANSMITTAL

     To tender your initial notes in this exchange offer, you must use one of
the three alternative procedures described below:

          (1) Regular delivery procedure: Complete, sign and date the letter of
     transmittal, or a facsimile of the letter of transmittal. Have the
     signatures on the letter of transmittal guaranteed if required by the
     letter of transmittal. Mail or otherwise deliver the letter of transmittal
     or the facsimile together with the certificates representing the initial
     notes being tendered and any other required documents to the exchange agent
     on or before 5:00 p.m., New York City time, on the expiration date.

          (2) Book-entry delivery procedure: Send a timely confirmation of a
     book-entry transfer of your initial notes, if this procedure is available,
     into the exchange agent's account at The Depository Trust Company in
     accordance with the procedures for book-entry transfer described under
     ' -- Book-Entry Delivery Procedure' below, on or before 5:00 p.m., New York
     City time, on the expiration date.

          (3) Guaranteed delivery procedure: If time will not permit you to
     complete your tender by using the procedures described in (1) or (2) above
     before the expiration date, comply with the guaranteed delivery procedures
     described under ' -- Guaranteed Delivery Procedure' below.

     The method of delivery of the initial notes, the letter of transmittal and
all other required documents is at your election and risk. Instead of delivery
by mail, we recommend that you use an overnight or hand-delivery service. If you
choose the mail, we recommend that you use registered mail, properly insured,
with return receipt requested. IN ALL CASES, YOU SHOULD ALLOW SUFFICIENT TIME TO
ASSURE TIMELY DELIVERY. You should not send any letters of transmittal or
initial notes to us. You must deliver all documents to the exchange agent at its
address provided below. You may also request your broker, dealer, commercial
bank, trust company or nominee to tender your initial notes on your behalf.

     Only a holder of initial notes may tender initial notes in this exchange
offer. A holder is any person in whose name initial notes are registered on our
books or any other person who has obtained a properly completed bond power from
the registered holder.

     If you are the beneficial owner of initial notes that are registered in the
name of a broker, dealer, commercial bank, trust company or other nominee and
you wish to tender your notes, you must contact that registered holder promptly
and instruct that registered holder to tender your notes on your behalf. If you
wish to tender your initial notes on your own behalf, you must, before
completing and executing the letter of transmittal and delivering your initial
notes, either make appropriate arrangements to register the ownership of these
notes in your name or obtain a properly completed bond power from the registered
holder. The transfer of registered ownership may take considerable time.

     You must have any signatures on a letter of transmittal or a notice of
withdrawal guaranteed by:

          (1) a member firm of a registered national securities exchange or of
     the National Association of Securities Dealers, Inc.,

          (2) a commercial bank or trust company having an office or
     correspondent in the United States, or

          (3) an eligible guarantor institution within the meaning of Rule
     17Ad-15 under the Exchange Act,

     unless the initial notes are tendered:

          (1) by a registered holder or by a participant in The Depository Trust
     Company whose name appears on a security position listing as the owner, who
     has not completed the box entitled 'Special Issuance Instructions' or
     'Special Delivery Instructions' on the letter of

                                       60



<PAGE>

     transmittal and only if the exchange notes are being issued directly to
     this registered holder or deposited into this participant's account at The
     Depository Trust Company, or

          (2) for the account of a member firm of a registered national
     securities exchange or of the National Association of Securities Dealers,
     Inc., a commercial bank or trust company having an office or correspondent
     in the United States or an eligible guarantor institution within the
     meaning of Rule 17Ad-15 under the Securities Exchange Act of 1934.

     If the letter of transmittal or any bond powers are signed by:

          (1) The recordholder(s) of the initial notes tendered: the signature
     must correspond with the name(s) written on the face of the initial notes
     without alteration, enlargement or any change whatsoever.

          (2) A participant in The Depository Trust Company: the signature must
     correspond with the name as it appears on the security position listing as
     the holder of the initial notes.

          (3) A person other than the registered holder of any initial notes:
     these initial notes must be endorsed or accompanied by bond powers and a
     proxy that authorize this person to tender the initial notes on behalf of
     the registered holder, in satisfactory form to us as determined in our sole
     discretion, in each case, as the name of the registered holder or holders
     appears on the initial notes.

          (4) Trustees, executors, administrators, guardians, attorneys-in-fact,
     officers of corporations or others acting in a fiduciary or representative
     capacity: these persons should so indicate when signing. Unless waived by
     us, evidence satisfactory to us of their authority to so act must also be
     submitted with the letter of transmittal.

BOOK-ENTRY DELIVERY PROCEDURE

     Any financial institution that is a participant in The Depository Trust
Company's systems may make book-entry deliveries of initial notes by causing The
Depository Trust Company to transfer these initial notes into the exchange
agent's account at The Depository Trust Company in accordance with The
Depository Trust Company's procedures for transfer. To effectively tender notes
through The Depository Trust Company, the financial institution that is a
participant in The Depository Trust Company will electronically transmit its
acceptance through the Automatic Tender Offer Program. The Depository Trust
Company will then edit and verify the acceptance and send an agent's message to
the exchange agent for its acceptance. An agent's message is a message
transmitted by The Depository Trust Company to the exchange agent stating that
The Depository Trust Company has received an express acknowledgment from the
participant in The Depository Trust Company tendering the notes that this
participant has received and agrees to be bound by the terms of the letter of
transmittal, and that we may enforce this agreement against this participant.
The exchange agent will make a request to establish an account for the initial
notes at The Depository Trust Company for purposes of the exchange offer within
two business days after the date of this prospectus.

     A delivery of initial notes through a book-entry transfer into the exchange
agent's account at The Depository Trust Company will only be effective if an
agent's message or the letter of transmittal or a facsimile of the letter of
transmittal with any required signature guarantees and any other required
documents is transmitted to and received by the exchange agent at the address
indicated below under ' -- Exchange Agent' on or before the expiration date
unless the guaranteed delivery procedures described below are complied with.
DELIVERY OF DOCUMENTS TO THE DEPOSITORY TRUST COMPANY DOES NOT CONSTITUTE
DELIVERY TO THE EXCHANGE AGENT.

GUARANTEED DELIVERY PROCEDURE

     If you are a registered holder of initial notes and desire to tender your
notes, and (1) these notes are not immediately available, (2) time will not
permit your notes or other required documents to reach the exchange agent before
the expiration date or (3) the procedures for book-

                                       61



<PAGE>

entry transfer cannot be completed on a timely basis and an agent's message
delivered, you may still tender in this exchange offer if:

          (1) you tender through a member firm of a registered national
     securities exchange or of the National Association of Securities Dealers,
     Inc., a commercial bank or trust company having an office or correspondent
     in the United States, or an eligible guarantor institution within the
     meaning of Rule 17Ad-15 under the Exchange Act,

          (2) on or before the expiration date, the exchange agent receives a
     properly completed and duly executed letter of transmittal or facsimile of
     the letter of transmittal, and a notice of guaranteed delivery,
     substantially in the form provided by us, with your name and address as
     holder of the initial notes and the amount of notes tendered, stating that
     the tender is being made by that letter and notice and guaranteeing that
     within three business days after the expiration date the certificates for
     all the initial notes tendered, in proper form for transfer, or a
     book-entry confirmation with an agent's message, as the case may be, and
     any other documents required by the letter of transmittal will be deposited
     by the eligible institution with the exchange agent, and

          (3) the certificates for all your tendered initial notes in proper
     form for transfer or a book-entry confirmation as the case may be, and all
     other documents required by the letter of transmittal are received by the
     exchange agent within three business days after the expiration date.

ACCEPTANCE OF INITIAL NOTES FOR EXCHANGE; DELIVERY OF EXCHANGE NOTES

     Your tender of initial notes will constitute an agreement between you and
us governed by the terms and conditions provided in this prospectus and in the
related letter of transmittal.

     We will be deemed to have received your tender as of the date when your
duly signed letter of transmittal accompanied by your initial notes tendered, or
a timely confirmation of a book-entry transfer of these notes into the exchange
agent's account at The Depository Trust Company with an agent's message, or a
notice of guaranteed delivery from an eligible institution is received by the
exchange agent.

     All questions as to the validity, form, eligibility, including time of
receipt, acceptance and withdrawal of tenders will be determined by us in our
sole discretion. Our determination will be final and binding.

     We reserve the absolute right to reject any and all initial notes not
properly tendered or any initial notes which, if accepted, would, in our opinion
or our counsel's opinion, be unlawful. We also reserve the absolute right to
waive any conditions of this exchange offer or irregularities or defects in
tender as to particular notes. Our interpretation of the terms and conditions of
this exchange offer, including the instructions in the letter of transmittal,
will be final and binding on all parties. Unless waived, any defects or
irregularities in connection with tenders of initial notes must be cured within
such time as we shall determine. We, the exchange agent or any other person will
be under no duty to give notification of defects or irregularities with respect
to tenders of initial notes. We and the exchange agent or any other person will
incur no liability for any failure to give notification of these defects or
irregularities. Tenders of initial notes will not be deemed to have been made
until such irregularities have been cured or waived. The exchange agent will
return without cost to their holders any initial notes that are not properly
tendered and as to which the defects or irregularities have not been cured or
waived as promptly as practicable following the expiration date.

     If all the conditions to the exchange offer are satisfied or waived on the
expiration date, we will accept all initial notes properly tendered and will
issue the exchange notes promptly thereafter. Please refer to the section of
this prospectus entitled ' -- Conditions to the Exchange Offer' below. For
purposes of this exchange offer, initial notes will be deemed to have been
accepted as validly tendered for exchange when, as and if we give oral or
written notice of acceptance to the exchange agent.

                                       62



<PAGE>

     We will issue the exchange notes in exchange for the initial notes tendered
pursuant to a notice of guaranteed delivery by an eligible institution only
against delivery to the exchange agent of the letter of transmittal, the
tendered initial notes and any other required documents, or the receipt by the
exchange agent of a timely confirmation of a book-entry transfer of initial
notes into the exchange agent's account at The Depository Trust Company with an
agent's message, in each case, in form satisfactory to us and the exchange
agent.

     If any tendered initial notes are not accepted for any reason provided by
the terms and conditions of this exchange offer or if initial notes are
submitted for a greater principal amount than the holder desires to exchange,
the unaccepted or non-exchanged initial notes will be returned without expense
to the tendering holder, or, in the case of initial notes tendered by book-
entry transfer procedures described above, will be credited to an account
maintained with the book-entry transfer facility, as promptly as practicable
after withdrawal, rejection of tender or the expiration or termination of the
exchange offer.

     By tendering into this exchange offer, you will irrevocably appoint our
designees as your attorney-in-fact and proxy with full power of substitution and
resubstitution to the full extent of your rights on the notes tendered. This
proxy will be considered coupled with an interest in the tendered notes. This
appointment will be effective only when, and to the extent that we accept your
notes in this exchange offer. All prior proxies on these notes will then be
revoked and you will not be entitled to give any subsequent proxy. Any proxy
that you may give subsequently will not be deemed effective. Our designees will
be empowered to exercise all voting and other rights of the holders as they may
deem proper at any meeting of note holders or otherwise. The initial notes will
be validly tendered only if we are able to exercise full voting rights on the
notes, including voting at any meeting of the note holders, and full rights to
consent to any action taken by the note holders.

WITHDRAWAL OF TENDERS

     Except as otherwise provided in this prospectus, you may withdraw tenders
of initial notes at any time before 5:00 p.m., New York City time, on the
expiration date.

     For a withdrawal to be effective, you must send a written or facsimile
transmission notice of withdrawal to the exchange agent before 5:00 p.m., New
York City time, on the expiration date at the address provided below under
' -- Exchange Agent' and before acceptance of your tendered notes for exchange
by us.

     Any notice of withdrawal must:

          (1) specify the name of the person having tendered the initial notes
     to be withdrawn,

          (2) identify the notes to be withdrawn, including, if applicable, the
     registration number or numbers and total principal amount of these notes,

          (3) be signed by the person having tendered the initial notes to be
     withdrawn in the same manner as the original signature on the letter of
     transmittal by which these notes were tendered, including any required
     signature guarantees, or be accompanied by documents of transfer sufficient
     to permit the trustee for the initial notes to register the transfer of
     these notes into the name of the person having made the original tender and
     withdrawing the tender,

          (4) specify the name in which any of these initial notes are to be
     registered, if this name is different from that of the person having
     tendered the initial notes to be withdrawn, and

          (5) if applicable because the initial notes have been tendered though
     the book-entry procedure, specify the name and number of the participant's
     account at The Depository Trust Company to be credited, if different than
     that of the person having tendered the initial notes to be withdrawn.

     We will determine all questions as to the validity, form and eligibility,
including time of receipt, of all notices of withdrawal and our determination
will be final and binding on all parties.

                                       63

CONDITIONS TO THE EXCHANGE OFFER

     We will complete this exchange offer only if:

          (1) there is no action or proceeding instituted or threatened in any
     court or before any governmental agency or body that in our judgment would
     reasonably be expected to prohibit, prevent or otherwise impair our ability
     to proceed with this exchange offer,

Accordingly, we will not recognize any gain or loss for accounting purposes. We
will amortize the costs of the exchange offer and the unamortized expenses
related to the issuance of the exchange notes over the term of the exchange
notes.

initial notes in this exchange offer, you will not be able to resell, offer to

                            DESCRIPTION OF THE NOTES

     The notes were issued under an indenture dated as of May 15, 1999 between
the Company, as issuer, and United States Trust Company of New York, as trustee
(the 'Trustee'), a copy of which is filed as an exhibit to the registration
statement relating to this exchange offer.

     The following summary of some provisions of the indenture does not purport
to be complete and is subject to, and qualified in its entirety by reference to,
the provisions of the notes and the indenture, including the definitions of some
terms contained in it and those terms made part of the indenture by reference to
the Trust Indenture Act. For definitions of some capitalized terms used in the
following summary, see ' -- Certain Definitions.' In this description, the word
'Company' refers only to CD Radio Inc. and not to any of its subsidiaries.

GENERAL

     The notes will be limited to $200,000,000 aggregate principal amount and
will mature on May 15, 2009.

     We will pay interest on each note at the rate set forth on the cover page
hereof from May 18, 1999 or from the most recent interest payment date to which
interest has been paid or duly provided for, payable in cash on May 15 and
November 15 of each year, commencing November 15, 1999, until we have paid or
duly provided for the payment of the principal of such note to the Person in
whose name the note (or any predecessor note) is registered at the close of
business on the May 1 or November 1 next preceding such interest payment date.
Interest will be computed on the basis of a 360-day year comprised of twelve
30-day months.

     We will pay the principal of, premium, if any, on and interest on the
notes, and holders may exchange and transfer the notes, at our office or agency
in The City of New York maintained for such purposes (which initially will be
the office of the Trustee). However, at our option, we may pay interest by check
mailed to the address of the Person entitled thereto as shown on the security
register. We will issue the notes only in fully registered form without coupons.
We will not charge holders any fee in connection with any registration of
transfer or exchange or redemption of notes, but we may require payment in
certain circumstances of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection therewith.

RANKING

     The notes will rank

      equal in right of payment with all of our existing and future
      unsubordinated obligations, including the Senior Discount Notes, and

      senior in right of payment to all of our existing and future obligations
      expressly subordinated in right of payment to the notes.

Under the indenture, we and our subsidiaries are entitled to incur, subject to
significant conditions and limitations, additional indebtedness, including
indebtedness secured by the issued and outstanding stock of Satellite CD Radio,
Inc. As of June 30, 1999, we had $480 million in aggregate principal amount of
indebtedness outstanding (including the notes) which ranked equal in right of
payment with the notes, all of which was secured. We currently have no
subordinated obligations outstanding.

     In addition, the notes will be effectively subordinated to all existing and
future obligations of our subsidiaries. As of September 30, 1999, our
subsidiaries had no liabilities outstanding.

                                       66



<PAGE>

SECURITY

     The exchange notes will be secured by a first priority perfected security
interest in all the issued and outstanding common stock of Satellite CD Radio,
Inc., our wholly owned subsidiary (the 'Pledged Stock'), on an equal basis with
holders of the Senior Discount Notes pursuant to the Pledge Agreement. We are
entitled to incur additional secured financing as set forth in 'Certain
Covenants -- Limitation on Indebtedness.' Any such secured financing with
respect to the Pledged Stock must be secured on an equal basis with the holders
of the notes. As of June 30, 1999, approximately $338 million of indebtedness
secured by the Pledged Stock was outstanding.

     So long as no Event of Default has occurred and is continuing, we are
entitled to exercise all voting rights with respect to the Pledged Stock,
provided that we cast no vote that is inconsistent with the provisions of the
indenture. Upon the occurrence of an Event of Default, the collateral agent
under the Pledge Agreement is entitled, subject to the provisions of an
intercreditor agreement between the Trustee and the trustee of the Senior
Discount Notes and subject as well to the satisfaction of any regulatory
requirements, to vote the Pledged Stock or realize upon and sell or otherwise
dispose of all or any part of the Pledged Stock and will apply the proceeds of
any sale or disposition,

          first to the payment of costs and expenses of sale,

          second to amounts due the collateral agent,

          third to the payment of all amounts due and unpaid on the notes and,
     if an event of default has occurred in connection with the Senior Discount
     Notes or with any other indebtedness secured by the Pledged Stock, the
     Senior Discount Notes or such other indebtedness, on an equal and ratable
     basis,

          finally, any surplus to us.

     Regulatory considerations may affect the collateral agent's ability to
exercise rights with respect to the Pledged Stock upon the occurrence of an
Event of Default. In particular, the Trustee under the indenture is not entitled
to exercise any rights with respect to the Pledged Stock upon the occurrence of
an Event of Default if such action would constitute or result in any assignment
of our FCC License or any change of control (whether as a matter of law or fact)
of the Company unless the prior approval of the FCC is first obtained. We cannot
assure you that any such required FCC approval can be obtained on a timely
basis, or at all.

     In addition, at the time we issued the initial notes, we applied
approximately $79.3 million of the net proceeds of this offering to purchase,
and we pledged to the Trustee in escrow for the benefit of the holders of the
notes, the Pledged Securities to provide for payment in full of the first six
scheduled interest payments due on the notes. The Pledged Securities were
pledged by us to the Trustee for the benefit of the holders of the notes
pursuant to the Collateral Pledge Agreement and will be held by the Trustee in
the Pledge Account. Immediately prior to each interest payment date on the notes
from November 15, 1999, through May 15, 2002, we may either deposit with the
Trustee, from funds otherwise available to us, cash sufficient to pay the
interest scheduled to be paid on such date or we may direct the Trustee to
release from the Pledge Account proceeds sufficient to pay interest then due. In
the event that we exercise the former option, we may thereafter direct the
Trustee to release to us proceeds or Pledged Securities from the Pledge Account
in like amount, provided that the balance remaining in such Pledge Account is
sufficient to pay all scheduled interest through May 15, 2002.

     Interest earned on the Pledged Securities will be added to the Pledge
Account. In the event that the funds or Pledged Securities held in the Pledge
Account exceed the amount sufficient, in the opinion of a nationally recognized
firm of independent public accountants selected by us, to provide for payment in
full of the first six scheduled interest payments due on the notes (or, in the
event an interest payment or payments have been made, an amount sufficient to
provide the payment in full of any interest payments remaining, up to and
including the sixth scheduled interest payment), the Trustee will release to us
at our request any such excess amount.

                                       67



<PAGE>

     Under the Collateral Pledge Agreement, assuming that we make the first six
scheduled interest payments on the notes in a timely manner, all of the Pledged
Securities will have been released from the Pledge Account, and the notes will
thereafter not be secured by the Pledged Securities.

     Except as set forth above, the notes are not secured by any lien on, or
other security interest in, any other properties or assets of the Company or
Satellite CD Radio, Inc.

SINKING FUND

     The notes will not be entitled to the benefit of any sinking fund.

REDEMPTION

     Except as set forth below, we are not entitled to redeem the notes at our
option prior to May 15, 2004.

     On and after May 15, 2004, we will be entitled to redeem all or a part of
the notes at our option, on not less than 30 nor more than 60 days' prior
notice, at the redemption prices (expressed as percentages of principal amount)
set forth below, together with accrued interest, if any, to the redemption date,
if redeemed during the 12-month period beginning on May 15 of the years
indicated below (subject to the right of holders of record on relevant record
dates to receive interest due on a relevant interest payment date):

</TABLE>

     In addition, at any time or from time to time prior to May 15, 2002, we are
entitled to redeem up to a maximum of 35% of the original aggregate principal
amount of the notes with the net proceeds of one or more equity offerings at a
redemption price (expressed as a percentage of principal amount on the
redemption date) of 114.50% plus accrued interest to the redemption date;
provided, however, that immediately after giving effect to such redemption, at
least 65% of the original aggregate principal amount of the notes remains
outstanding; provided further, however, that notice of such redemption shall be
given within 60 days of the closing of such equity offering.

     If at any time we are redeeming less than all the notes, the Trustee will
select the particular notes to be redeemed not more than 60 days prior to the
redemption date by such method as the Trustee shall deem fair and appropriate.

     We will send a notice of redemption by mail, first-class postage prepaid,
at least 30 but not more than 60 days before the redemption date to each holder
of notes to be redeemed at its registered address. If we are redeeming any note
in part only, notice of redemption relating to such note will identify the
portion of the principal amount thereof to be redeemed. We will issue a new note
in a principal amount equal to the unredeemed portion thereof in the name of the
holder thereof upon cancellation of the original note.

     On and after any redemption date, interest will cease to accrue on notes or
portions thereof called for redemption and accepted for payment.

CERTAIN COVENANTS

LIMITATION ON INDEBTEDNESS

     The Company will not, and will not permit any Restricted Subsidiary to,
create, assume, issue, guarantee or in any manner become directly or indirectly
liable for or with respect to the payment of, or otherwise incur (collectively,
to 'incur'), any Indebtedness, except for Permitted Indebtedness; provided,
however, that

      the Company will be permitted to incur Indebtedness and

the application of the net proceeds therefrom), the ratio of

          (1) Total Consolidated Indebtedness to

          (2) Adjusted Consolidated Operating Cash Flow for the latest four

     held by a Restricted Subsidiary); or

          (4) the making of any Investment (other than a Permitted Investment)
     in any Person

          (A) no Default or Event of Default shall have occurred and be
     continuing at the time of or after giving effect to such Restricted
     Payment;

          (B) immediately after giving effect to such Restricted Payment, the

             (a) the difference between (x) the Cumulative Available Cash Flow
        determined at the time of such Restricted Payment and (y) 150% of the
        cumulative Consolidated Interest Expense of the Company determined for
        the period commencing on November 26, 1997 and ending on the last day of
        the latest fiscal quarter for which consolidated financial statements of
        the Company are available preceding the date of such Restricted Payment
        plus

             (b) the aggregate Net Cash Proceeds received by the Company from
        the issue or sale (other than to any Restricted Subsidiary) of Qualified
        Capital Stock of the Company after January 1, 1998, plus

                                       69



<PAGE>

        Operating Cash Flow of the Company, an amount equal to the sum of
        (i) the net reduction in Investments (other than the Permitted
        Investments) in any Person resulting from the payment in cash of
        dividends, repayments of loans or advances or other transfers of assets,
        in each case to the Company or any Restricted Subsidiary after
        November 26, 1997 from such Person and (ii) the portion (proportionate
        to the Company's equity interest in such Subsidiary) of the fair market
        value of the net assets of any Unrestricted Subsidiary at the time such
        Unrestricted Subsidiary is designated a Restricted Subsidiary; provided,
        however, that in the case of (i) or (ii) above, the foregoing sum shall
        not exceed the aggregate amount of Investments previously made (and
        treated as a Restricted Payment) by the Company or any Restricted
        Subsidiary in such Person or Unrestricted Subsidiary, minus

             (e) the sum of 80% of the outstanding principal amount of the Notes
        and all Indebtedness incurred pursuant to clause 1(b) of the definition
        of Permitted Indebtedness.

For purposes of determining the amount expended for Restricted Payments,
property other than cash shall be valued at its Fair Market Value.

     The provisions of this covenant will not prohibit, so long as, with respect
to clauses (2) through (8) below, no Default or Event of Default shall have
occurred and be continuing:

          (1) the payment of any dividend or other distribution within 60 days
     after the date of declaration thereof if at such date of declaration such
     payment complied with the provisions of the Indenture, and such payment
     will be deemed to have been paid on the date of declaration for purposes of
     the calculation in the foregoing paragraph;

          (2) the purchase, redemption, retirement or other acquisition of any
     shares of Capital Stock of the Company in exchange for, or out of the Net
     Cash Proceeds of a substantially concurrent issue and sale (other than to a
     Restricted Subsidiary) of, shares of Qualified Capital Stock of the
     Company;

          (3) the purchase, redemption, retirement, defeasance or other
     acquisition or retirement for value of Subordinated Indebtedness made by
     exchange for, or out of the Net Cash Proceeds of a substantially concurrent
     issue or sale (other than to a Restricted Subsidiary) of, Qualified Capital
     Stock of the Company;

          (4) the purchase of (a) any Subordinated Indebtedness at a purchase
     price not greater than 101% of the principal amount or accreted value
     thereof, as the case may be, together with accrued interest, if any, in the
     event of a Change of Control in accordance with provisions similar to the
     'Purchase of Notes upon a Change of Control' covenant or (b) any Preferred
     Stock of the Company at a purchase price not greater than 101% of the
     liquidation preference thereof, together with accrued dividends, if any, in
     the event of a Change of Control in accordance with provisions similar to
     the 'Purchase of Notes upon a Change of Control' covenant; provided,
     however, that, in each case, prior to such purchase the Company has made
     the Change of Control Offer as provided in such covenant with respect to
     the Notes and has purchased all Notes validly tendered for payment in
     connection with such Change of Control Offer;

          (5) the purchase, redemption, defeasance or other acquisition or
     retirement for value of Subordinated Indebtedness in exchange for, or out
     of the Net Cash Proceeds of a substantially concurrent incurrence (other
     than to a Restricted Subsidiary) of, new Subordinated Indebtedness so long
     as

             (a) the principal amount of such new Subordinated Indebtedness does
        not exceed the principal amount (or, if such Subordinated Indebtedness
        being refinanced provides for an amount less than the principal amount
        thereof to be due and payable upon a declaration of acceleration
        thereof, such lesser amount as of the date of determination) of the
        Subordinated Indebtedness being so purchased, redeemed, defeased,
        acquired or retired, plus the lesser of the amount of any premium
        required to be paid in connection with such refinancing pursuant to the
        terms of the Subordinated Indebtedness being refinanced or the amount of
        any premium reasonably determined by the Company as necessary to

                                       70



<PAGE>

        accomplish such refinancing, plus, in either case, the amount of
        expenses of the Company incurred in connection with such refinancing,

             (b) such new Subordinated Indebtedness is subordinated to the Notes
        to the same extent as such Subordinated Indebtedness so purchased,
        redeemed, defeased, acquired or retired and

             (c) such new Subordinated Indebtedness has an Average Life longer
        than the Average Life of the Notes and a final Stated Maturity of
        principal later than the Stated Maturity of principal of the Notes;

          (6) the purchase of any Subordinated Indebtedness at a purchase price
     not greater than 100% of the principal amount or accreted value thereof, as
     the case may be, together with accrued interest, if any, following an Asset
     Sale in accordance with provisions similar to the 'Limitation on Sale of
     Assets' covenant; provided, however, that prior to making any such purchase
     the Company has made the Excess Proceeds Offer as provided in such covenant
     with respect to the Notes and has purchased all Notes validly tendered for
     payment in connection with such Excess Proceeds Offer;

          (7) the payment of cash dividends on outstanding shares of Series C
     Preferred Stock of the Company out of the Net Cash Proceeds of a
     substantially concurrent issue and sale (other than to a Restricted
     Subsidiary) of Common Stock of the Company; and

          (8) any other Restricted Payments in an aggregate amount not to exceed
     $15.0 million.

     In determining the amount of Restricted Payments permissible under this
covenant, amounts expended pursuant to clauses (1), (2), (3), (4), (6), (7) and
(8) above shall be included as Restricted Payments.

LIMITATION ON ISSUANCES AND SALES OF CAPITAL STOCK OF RESTRICTED SUBSIDIARIES

     The Company will not permit

      any Restricted Subsidiary to issue any Capital Stock (other than to the
      Company or a Restricted Subsidiary); and

      any Person (other than the Company or a Restricted Subsidiary) to own any
      Capital Stock of any Restricted Subsidiary;

provided, however, that this covenant shall not prohibit

          (1) the issuance or sale of all, but not less than all, of the issued
     and outstanding Capital Stock of any Restricted Subsidiary owned by the
     Company or any Restricted Subsidiary in compliance with the other
     provisions of the Indenture; or

          (2) the ownership by directors of directors' qualifying shares or the
     ownership by foreign nationals of Capital Stock of any Restricted
     Subsidiary, to the extent mandated by applicable law.

LIMITATION ON LIENS

     The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, create, incur, assume or suffer to exist any Lien of any
kind, other than Permitted Liens, on or with respect to any of its property or
assets, including any shares of stock or Indebtedness of any Restricted
Subsidiary, whether owned at the date of the Indenture or thereafter acquired,
or any income, profits or proceeds therefrom, or assign or otherwise convey any
right to receive income thereon, unless

      in the case of any Lien securing Subordinated Indebtedness, the Notes are
      secured by a Lien on such property, assets or proceeds that is senior in
      priority to such Lien; and

      in the case of any other Lien, the Notes are equally and ratably secured;

                                       71



<PAGE>

PURCHASE OF NOTES UPON A CHANGE OF CONTROL

     If a Change of Control shall occur at any time, then each holder of Notes
will have the right to require that the Company purchase such holder's Notes, in
whole or in part in integral multiples of $1,000 principal amount, at a purchase
price (the 'Change of Control Purchase Price') in cash in an amount equal to
101% of the principal amount of such Notes as of the date of purchase, plus
accrued and unpaid interest, if any, to the date of purchase (the 'Change of
Control Purchase Date'), pursuant to the offer described below (the 'Change of
Control Offer') and the other procedures set forth in the Indenture.

     Within 15 days following any Change of Control, the Company will notify the
Trustee thereof and give written notice of such Change of Control to each holder
of Notes by first-class mail, postage prepaid, at the address of such holder
appearing in the security register, stating, among other things,

      the purchase price and the purchase date, which will be a business day no
      earlier than 30 days nor later than 60 days from the date such notice is
      mailed, or such later date as is necessary to comply with requirements
      under the Exchange Act or any applicable securities laws or regulations;

      that any Note not tendered will continue to accrue interest;

      that, unless the Company defaults in the payment of the purchase price,
      any Notes accepted for payment pursuant to the Change of Control Offer
      will cease to accrue interest after the Change of Control Purchase Date;
      and

      certain other procedures that a holder of Notes must follow to accept a
      Change of Control Offer or to withdraw such acceptance.

The Company will have no obligation to purchase any Notes in a Change of Control
Offer if no Notes are tendered by the holders thereof.

     If a Change of Control Offer is made, we cannot assure you that we will
have available funds sufficient to pay the Change of Control Purchase Price for
all the Notes that might be delivered by holders of the Notes seeking to accept
the Change of Control Offer. Our failure to make or consummate the Change of
Control Offer or pay the Change of Control Purchase Price when due would result
in an Event of Default and would give the Trustee and the holders of the Notes
the rights described under ' -- Events of Default.'

     One of the events that constitutes a Change of Control under the Indenture
is the disposition of 'all or substantially all' of our assets. This term has
not been interpreted under New York law (which is the governing law of the
Indenture) to represent a specific quantitative test. Therefore, if holders of
the Notes elect to require us to purchase the Notes and we elect to contest such
election, we can not assure you how a court interpreting New York law would
interpret the phrase.

     The existence of a holder's right to require us to purchase such holder's
Notes upon a Change of Control may deter a third party from acquiring the
Company in a transaction that constitutes a Change of Control.

     The definition of 'Change of Control' in the Indenture is limited in scope.
The provisions of the Indenture may not afford holders of notes the right to
require us to purchase such Notes in the event of a highly leveraged transaction
or certain transactions with our management or our affiliates, including a
reorganization, restructuring, merger or similar transaction involving the
Company (including, in certain circumstances, an acquisition of the Company by
management or its affiliates) that may adversely affect holders of the Notes, if
such transaction is not a transaction defined as a Change of Control. See
' -- Certain Definitions' for the definition of 'Change of Control.' A
transaction involving our management or our affiliates, or a transaction
involving a recapitalization of the Company, would result in a Change of Control
only if it is the type of transaction specified by such definition.

     The Company will comply to the extent applicable with the requirements of
the tender offer rules, including Rule 14e-1 under the Exchange Act, and any
other applicable securities laws and regulations in connection with a Change of
Control Offer.

LIMITATION ON SALE-LEASEBACK TRANSACTIONS

     The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, enter into any sale-leaseback transaction involving any
of its assets or properties whether now owned or hereafter acquired, whereby the
Company or a Restricted Subsidiary sells or transfers such assets or properties
and then or thereafter leases such assets or properties or any part thereof or
any other assets or properties which the Company or such Restricted Subsidiary,
as the case may be, intends to use for substantially the same purpose or
purposes as the assets or properties sold or transferred.

     The foregoing restriction does not apply to any sale-leaseback transaction
if:

      the lease is for a period, including renewal rights, of not in excess of
      three years;

      the transaction is solely between the Company and any Restricted
      Subsidiary or solely between Restricted Subsidiaries; or

      the Company or such Restricted Subsidiary, within 12 months after the sale
      or transfer of any assets or properties is completed, applies an amount
      not less than the net proceeds received from such sale in accordance with
      paragraph (b) of the 'Limitation on Sale of Assets' covenant described
      below.

LIMITATION ON SALE OF ASSETS

     (a) The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, engage in any Asset Sale unless:

          (1) the consideration received by the Company or such Restricted
     Subsidiary for such Asset Sale is not less than the Fair Market Value of
     the shares or assets sold (as determined by the Board of Directors, whose
     determination shall be conclusive and evidenced by a Board Resolution); and

          (2) the consideration received by the Company or the relevant
     Restricted Subsidiary in respect of such Asset Sale consists of at least
     80% cash or Cash Equivalents.

     (b) If the Company or any Restricted Subsidiary engages in an Asset Sale,
the Company is entitled to use the Net Cash Proceeds thereof within 12 months
after the later of such Asset Sale or the receipt of such Net Cash Proceeds:

          (1) to permanently repay or prepay any then outstanding Pari Passu
     Indebtedness;

          (2) to invest in any one or more businesses, capital expenditures or
     other tangible assets of the Company or any Restricted Subsidiary, in each
     case, engaged, used or useful in the CD Radio Business (or enter into a
     legally binding agreement to do so within 6 months); or

          (3) to invest in properties or assets that replace the properties and
     assets that are the subject of such Asset Sale (or enter into a legally
     binding agreement to do so within 6 months).

If any such legally binding agreement to invest such Net Cash Proceeds is
terminated, then the Company is entitled, within 90 days of such termination or
within 12 months of such Asset Sale, whichever is later, to apply or invest such
Net Cash Proceeds as provided in clause (1), (2) or (3) (without regard to the
parenthetical contained in clause (2) or (3)) above. The amount of such Net Cash
Proceeds not so used as set forth above in this paragraph (b) constitutes
'Excess Proceeds.'

     (c) When the aggregate amount of Excess Proceeds exceeds $10.0 million the
Company will (i) comply with the provisions of Section 1016(c) of the Senior
Discount Notes Indenture that require the Company to make an offer to purchase
Senior Discount Notes, if applicable, and

                                       73



<PAGE>

(ii) within 30 business days after the completion of such offer, or if such
provisions are not applicable, within 30 days after the time Excess Proceeds
exceed $10.0 million, make an offer to purchase (an 'Excess Proceeds Offer')
from all holders of Notes and, if the Company so elects, from holders of Pari
Passu Indebtedness, on a pro rata basis, in accordance with the procedures set
forth below, the maximum principal amount of Notes and, if applicable, such Pari
Passu Indebtedness that may be purchased with the Excess Proceeds. In the case
of other Pari Passu Indebtedness that is issued at a discount to its face
amount, the requirement that Notes and other Pari Passu Indebtedness be
purchased on a 'pro rata basis' means that the amount of such other Pari Passu
Indebtedness to be purchased will be based on the amount to which the Pari Passu
Indebtedness has accreted in value for purposes of determining the amount that
would be payable thereon in the event of the occurrence of an event of default
(or similar event) under such other Pari Passu Indebtedness. The offer price as
to each Note and such other Pari Passu Indebtedness shall be payable in cash in
an amount equal to 100% of the principal amount, or accreted value, as the case
may be, of such Note or other Pari Passu Indebtedness (without premium) as of
the date of purchase plus accrued interest, if any (the 'Offered Price'), to the
date such Excess Proceeds Offer is consummated (the 'Offer Date').

     To the extent that the aggregate principal amount, or accreted value, as
the case may be, of Notes and such other Pari Passu Indebtedness tendered
pursuant to an Excess Proceeds Offer is less than the Excess Proceeds relating
thereto, the Company is entitled to use such additional Excess Proceeds for
general corporate purposes or to fund an offer to redeem any outstanding
Subordinated Indebtedness in accordance with provisions similar to this
'Limitation on Sale of Assets' covenant.

     If the aggregate principal amount of Notes and such other Pari Passu
Indebtedness validly tendered and not withdrawn by holders thereof exceeds the
Excess Proceeds, the Company will select Notes and such other Pari Passu
Indebtedness to be purchased on a pro rata basis as described in the second
preceding paragraph. Upon completion of such offer to purchase, the amount of
Excess Proceeds will be reset to zero.

     (d) If the Company becomes obligated to make an Excess Proceeds Offer
pursuant to paragraph (c) above, the Company will purchase Notes, at the option
of the holder thereof, in whole or in part in integral multiples of $1,000, on a
date that is not earlier than 30 days and not later than 60 days from the date
the notice is given to holders, or such later date as may be necessary for the
Company to comply with the requirements under the Exchange Act or any other
applicable securities laws or regulations, subject to proration in the event the
amount of Excess Proceeds is less than the aggregate Offered Price of all Notes
and such other Pari Passu Indebtedness tendered.

     (e) The Company will comply to the extent applicable with the requirements
of the tender offer rules, including Rule 14e-1 under the Exchange Act, and any
other applicable securities laws and regulations in connection with an Excess
Proceeds Offer.

LIMITATION ON TRANSACTIONS WITH AFFILIATES

     The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, enter into or suffer to exist any transaction or series
of related transactions (including the sale, purchase, exchange or lease of
assets, property or services) with, or for the benefit of, any Affiliate of the
Company (other than the Company or a Restricted Subsidiary) unless:

          (1) such transaction or series of related transactions is on terms
     that are no less favorable to the Company or such Restricted Subsidiary, as
     the case may be, as determined in good faith by the Board of Directors,
     whose determination shall be conclusive and evidenced by a Board
     Resolution, than those that could have been obtained in an arm's-length
     transaction with unrelated third parties who are not Affiliates;

          (2) with respect to any transaction or series of related transactions
     involving aggregate consideration equal to or greater than $2.5 million,
     the Company shall have delivered an officers' certificate to the Trustee
     certifying that such transaction or series of related

                                       74



<PAGE>

     transactions complies with clause (1) above and such transaction or series
     of related transactions has been approved by a majority of the
     Disinterested Directors of the Board of Directors of the Company, or the
     Company has obtained a written opinion from a nationally recognized
     investment banking firm to the effect that such transaction or series of
     related transactions is fair to the Company or such Restricted Subsidiary,
     as the case may be, from a financial point of view; and

          (3) with respect to any transaction or series of related transactions
     including aggregate consideration in excess of $10.0 million or in the
     event no members of the Board of Directors of the Company are Disinterested
     Directors with respect to any transaction or series of transactions
     included in clause (2), the Company will obtain an opinion from a
     nationally recognized investment banking firm as described above;

provided, however, that this covenant will not restrict

          (1) any transaction by the Company or any Restricted Subsidiary with
     an Affiliate directly related to the purchase, sale or distribution of
     products in the ordinary course of business consistent with industry
     practice,

          (2) the Company from paying reasonable and customary regular
     compensation and fees to directors of the Company or any Restricted
     Subsidiary who are not employees of the Company or any Restricted
     Subsidiary,

          (3) the payment of compensation (including stock options and other
     incentive compensation) to officers and other employees the terms of which
     are approved by the Board of Directors,

          (4) the Company or any Restricted Subsidiary from making any
     Restricted Payment in compliance with the 'Limitation on Restricted
     Payments' covenant (including pursuant to the second paragraph thereof),

          (5) transactions between the Company and Batchelder & Partners Inc.
     pursuant to agreements in effect on November 26, 1997; provided, however,
     that the Company will not, and will not permit any Restricted Subsidiary to
     amend, modify or in any way alter, other than an extension of the term
     thereof, the terms of any such agreement in a manner materially adverse to
     the holders of the Notes,

          (6) transactions among the Company and its Restricted Subsidiaries, or

          (7) amendments to the Loral Satellite Contract; provided, however,
     that the Company will not amend, modify or in any way alter the terms of
     such agreement in a manner materially adverse to the holders of the Notes.

     Under Delaware corporate law, the Disinterested Directors' fiduciary
obligations require that they act in good faith in a manner which they
reasonably believe to be in the best interests of the Company and its
stockholders, which may not necessarily be the same as those of holders of the
notes.

LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED
SUBSIDIARIES

     The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, create or otherwise cause or suffer to exist or become
effective any encumbrance or restriction of any kind on the ability of any
Restricted Subsidiary to:

          (a) pay dividends, in cash or otherwise, or make any other
     distributions on or in respect of its Capital Stock;

          (b) pay any Indebtedness owed to the Company or any other Restricted
     Subsidiary;

          (c) make Investments in the Company or any other Restricted
     Subsidiary;

          (d) transfer any of its properties or assets to the Company or any
     other Restricted Subsidiary; or

          (e) guarantee any Indebtedness of the Company or any other Restricted
     Subsidiary,

                                       75



<PAGE>

except for such encumbrances or restrictions existing under or by reason of

          (1) any agreement in effect on the Issue Date,

          (2) applicable law or judicial or regulatory action,

          (3) customary non-assignment provisions of any lease governing a
     leasehold interest of the Company or any Restricted Subsidiary,

          (4) any agreement or other instrument of a Person acquired by the
     Company or any Restricted Subsidiary in existence at the time of such
     acquisition (but not created in contemplation thereof), which encumbrance
     or restriction is not applicable to any Person, or the properties or assets
     of any Person, other than the Person, or the property or assets of the
     Person, so acquired and the Subsidiaries of such Person,

          (5) any mortgage or other Lien on real property acquired or improved
     by the Company or any Restricted Subsidiary after the date of the Indenture
     that prohibit transfers of the type described in (d) above with respect to
     such real property,

          (6) any encumbrance or restriction contained in contracts for sales of
     assets permitted by the 'Limitation on Sale of Assets' covenant with
     respect to the assets to be sold pursuant to such contract;

          (7) any such customary encumbrance or restriction contained in a
     security document creating a Permitted Lien to the extent relating to the
     property or asset subject to such Permitted Lien;

          (8) any agreement or other instrument governing any Pari Passu
     Indebtedness if such encumbrance or restriction applies only

             (x) to amounts which at any point in time (other than during such
        periods as are described in clause (y)) (a) exceed amounts due and
        payable (or which are to become due and payable within 30 days) in
        respect of the Notes or the Indenture for interest, premium and
        principal (after giving effect to any realization by the Company under
        any applicable Currency Agreement), or (b) if paid, would result in an
        event described in the following clause (y) of this clause (8), or

             (y) during the pendency of any event that causes, permits or, after
        notice or lapse of time, would cause or permit the holder(s) of the
        Indebtedness governed by such agreement or instrument to declare any
        such Indebtedness to be immediately due and payable or require cash
        collateralization or cash cover for such Indebtedness for so long as
        such cash collateralization or cash cover has not been provided; or

          (9) the refinancing of Indebtedness incurred under the agreements
     described in clause (5) above, so long as such encumbrances or restrictions
     are no less favorable in any material respect to the Company or any
     Restricted Subsidiary than those contained in the respective agreement as
     in effect on the Issue Date.

INSURANCE

     (a) The Company will maintain launch insurance with respect to each
satellite launch covering the period from the launch to 180 days following the
launch of each satellite in an amount equal to or greater than the sum of

          (1) the cost to replace such satellite with a satellite of comparable
     or superior technological capability (as determined by the Board of
     Directors, whose determination shall be conclusive and evidenced by a Board
     Resolution) and having at least as much transmission capacity as the
     satellite to be replaced,

          (2) the cost to launch a replacement satellite pursuant to the
     contract whereby a replacement satellite will be launched and

                                       76



<PAGE>

          (3) the cost of launch insurance for such replacement or, in the event
     that the Company has reason to believe that the cost of obtaining
     comparable insurance for a replacement would be materially higher, the
     Company's best estimate of the cost of such comparable insurance.

Notwithstanding the foregoing, the Company will not be obligated to maintain
insurance pursuant to this paragraph (a) with respect to (1) the launch of its
first satellite and (2) any subsequent launch not preceded by a launch failure
or failure of any satellite within 180 days from the date of its launch;
provided, however, that the Company's spare satellite shall be under
construction in accordance with the terms of the Loral Satellite Contract or the
Company shall have otherwise obtained a spare satellite.

     (b) The Company will maintain full in-orbit insurance with respect to each
satellite it owns and launches in an amount at least equal to

          (1) the cost to replace such satellite with a satellite of comparable
     or superior technological capability (as determined by the Board of
     Directors, whose determination shall be conclusive and evidenced by a Board
     Resolution) and having at least as much transmission capacity as the
     satellite to be replaced,

          (2) the cost to launch a replacement satellite pursuant to the
     contract pursuant to which a replacement satellite will be launched and

          (3) the cost of launch insurance for such replacement or, in the event
     that the Company has reason to believe that the cost of obtaining
     comparable insurance for a replacement would be materially higher, the
     Company's best estimate of the cost of such comparable insurance.

The in-orbit insurance required by this paragraph will provide that if 50% or
more of a satellite's capacity is lost, the full amount of insurance will become
due and payable, and that if a satellite is able to maintain more than 50% but
less than 100% of its capacity, a portion of such insurance will become due and
payable.

     (c) In the event that the Company receives proceeds from insurance relating
to any satellite, the Company is entitled to use all or a portion of such
proceeds to repay any vendor or third-party purchase money financing pertaining
to such satellite that is required to be repaid by reason of the loss giving
rise to such insurance proceeds. The Company will use the remainder of such
proceeds to develop and construct a replacement satellite; provided, however,
that

          (1) such replacement satellite is of comparable or superior
     technological capability as compared with the satellite being replaced and
     has at least as much transmission capacity as the satellite being replaced
     (as determined by the Board of Directors, whose determination shall be
     conclusive and evidenced by a Board Resolution);

          (2) the Company will have sufficient funds (together with the proceeds
     of any business interruption insurance) to service the Company's projected
     debt service requirements until the scheduled launch of the Company's spare
     satellite and for one year thereafter and to develop and construct such
     replacement satellite; and

          (3) the Company's spare satellite is scheduled to be launched within
     12 months of the receipt of such proceeds.

Any such proceeds not used as permitted by this paragraph shall constitute
'Excess Proceeds' for purposes of the 'Limitation on Sale of Assets' covenant.

PROVISION OF FINANCIAL STATEMENTS AND REPORTS

     The Company will file on a timely basis with the Commission, to the extent
such filings are accepted by the Commission and whether or not the Company has a
class of securities registered under the Exchange Act, the annual reports,
quarterly reports and other documents that the Company would be required to file
if it were subject to Section 13 or 15 of the Exchange Act. The Company will
also be required

      to file with the Trustee, and provide to each holder of Notes, without
      cost to such holder, copies of such reports and documents within 15 days
      after the date on which the Company

                                       77



<PAGE>

      files such reports and documents with the Commission or the date on which
      the Company would be required to file such reports and documents if the
      Company were so required, and

      if filing such reports and documents with the Commission is not accepted
      by the Commission or is prohibited under the Exchange Act, to supply at
      the Company's cost copies of such reports and documents to any prospective
      holder of Notes promptly upon written request.

CONSOLIDATION, MERGER AND SALE OF ASSETS

     The Company will not in a single transaction or a series of related
transactions consolidate with or merge with or into any other Person or sell,
assign, convey, transfer, lease or otherwise dispose of all or substantially all
of its properties and assets as an entirety to any Person or Persons, and the
Company will not permit any Restricted Subsidiary to enter into any such
transaction, or series of transactions, if such transaction or series of
transactions, in the aggregate, would result in the sale, assignment,
conveyance, transfer, lease or other disposition of all or substantially all of
the properties and assets of the Company and its Restricted Subsidiaries on a
consolidated basis to any Person or Persons, unless:

          (1) either (a) the Company shall be the surviving corporation or
     (b) the Person (if other than the Company) formed by such consolidation or
     into which the Company or the Company and its Restricted Subsidiaries is
     merged or the Person which acquires by sale, conveyance, transfer, lease or
     other disposition, all or substantially all of the properties and assets of
     the Company or the Company and its Restricted Subsidiaries, as the case may
     be (the 'Surviving Entity') (i) shall be a corporation organized and
     validly existing under the laws of the United States of America, any state
     thereof or the District of Columbia and (ii) shall expressly assume, by an
     indenture supplemental to the Indenture executed and delivered to the
     Trustee, in form satisfactory to the Trustee, the Company's obligations for
     the due and punctual payment of the principal of (or premium, if any, on)
     and interest on all the Notes and the performance and observance of every
     covenant of the Indenture on the part of the Company to be performed or
     observed;

          (2) immediately after giving effect to such transaction or series of
     transactions on a pro forma basis (and treating any obligation of the
     Company or any Restricted Subsidiary in connection with or as a result of
     such transaction as having been incurred at the time of such transaction),
     no Default or Event of Default shall have occurred and be continuing;

          (3) immediately after giving effect to such transaction or series of
     transactions on a pro forma basis (on the assumption that the transaction
     or series of transactions occurred on the first day of the latest four
     fiscal quarters for which consolidated financial statements of the Company
     are available prior to the consummation of such transaction or series of
     transactions with the appropriate adjustments with respect to the
     transaction or series of transactions, including the incurrence and
     repayment of any Indebtedness incident to such transaction, being included
     in such pro forma calculation), the Company (or the Surviving Entity if the
     Company is not the continuing obligor under the Indenture) could incur at
     least $1.00 of additional Indebtedness (other than Permitted Indebtedness)
     under the proviso to the 'Limitation on Indebtedness' covenant; provided,
     however, that this clause (3) shall not apply to a consolidation, merger or
     sale, assignment, conveyance, transfer, lease or other disposition of all
     or substantially all of the properties and assets of the Company and its
     Restricted Subsidiaries if

             (A) all Liens and Indebtedness of the Company or the Surviving
        Entity, as the case may be, and its Restricted Subsidiaries outstanding
        immediately after such transaction would, if incurred at such time, have
        been permitted to be incurred (and all such Liens and Indebtedness,
        other than the Liens and Indebtedness of the Company and its Restricted
        Subsidiaries outstanding immediately prior to the transaction, shall be
        deemed to have been incurred at such time) for all purposes of the
        Indenture and

                                       78



<PAGE>

             (B) immediately after giving effect to such transaction or series
        of transactions on a pro forma basis (and treating any obligation of the
        Company or any Restricted Subsidiary incurred in connection with or as a
        result of such transaction or series of transactions as having been
        incurred at the time of such transaction), the Consolidated Net Worth of
        the Company (or of the Surviving Entity if the Company is not the
        continuing obligor under the Indenture) is equal to or greater than the
        Consolidated Net Worth of the Company immediately prior to such
        transaction or series of transactions;

          (4) if any of the property or assets of the Company or any of its
     Restricted Subsidiaries would thereupon become subject to any Lien, the
     provisions of the 'Limitation on Liens' covenant are complied with; and

          (5) the Company or the Surviving Entity shall have delivered to the
     Trustee an officers' certificate and an opinion of counsel, each stating
     that such consolidation, merger, sale, assignment, conveyance, transfer,
     lease or other disposition and such supplemental indenture comply with the
     terms of the Indenture.

     Upon any consolidation or merger, or any sale, assignment, conveyance,
transfer, lease or other disposition of all of substantially all of the
properties and assets of the Company in accordance with the immediately
preceding paragraph in which the Company is not the continuing obligor under the
Indenture, the Surviving Entity shall succeed to, and be substituted for, and
may exercise every right and power of, the Company under the Indenture, with the
same effect as if such successor had been named as the Company therein. When a
successor assumes all the obligations of its predecessor under the Indenture and
the Notes, the predecessor shall be released from those obligations; provided,
however, that in the case of a transfer by lease, the predecessor shall not be
released from the payment of principal and interest on the Notes.

EVENTS OF DEFAULT

     The following will be 'Events of Default' under the Indenture:

          (1) as to any interest payment date occuring on or prior to May 15,
     2002, default in the payment of any interest on any Note when it becomes
     due and payable; and as to any interest payment date thereafter, any
     default in the payment of interest on any Note continued for 30 days;

     default or breach for a period of 30 days after written notice shall have

     by the holders of at least 25% in aggregate principal amount of the Notes
     then outstanding;

<PAGE>

          (6) one or more final judgments, orders or decrees of any court or
     regulatory agency shall be rendered against the Company or any Subsidiary
     of the Company or their respective properties for the payment of money,
     either individually or in an aggregate amount, in excess of $10.0 million
     and either (A) an enforcement proceeding shall have been commenced by any
     creditor upon such judgment or order or (B) there shall have been a period
     of 30 consecutive days during which a stay of enforcement of such judgment
     or order, by reason of a pending appeal or otherwise, was not in effect;

          (7) any provision of the Collateral Documents shall cease, for any
     reason, to be in full force and effect in any material respect, or the
     Company shall so assert in writing; or the Trustee or the Collateral Agent,
     as the case may be, shall cease to have a first priority perfected security
     interest in the Pledged Stock or the Pledged Securities or the Pledge
     Account, as the case may be (other than by reason of the release of any
     such security interest in accordance with the Collateral Documents), or any
     representation, warranty or certification of the Company made in or
     pursuant to the Collateral Documents shall be false in any material respect
     as of the date when made; or

          (8) the occurrence of certain events of bankruptcy, insolvency or
     reorganization with respect to the Company or any Subsidiary of the
     Company.

     If an Event of Default (other than an Event of Default specified in clause
(8) above) shall occur and be continuing, the Trustee or the holders of not less
than 25% in aggregate principal amount of the Notes then outstanding, by written
notice to us (and to the Trustee if such notice is given by the holders), may,
and the Trustee upon the written request of such holders, will declare the
principal of, premium, if any, and accrued interest on all of the outstanding
Notes immediately due and payable, and upon any such declaration all such
amounts payable in respect of the Notes shall become immediately due and
payable. If an Event of Default specified in clause (8) above occurs and is
continuing, then the principal of, premium, if any, and accrued interest on all
of the outstanding Notes shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
holder of Notes.

     At any time after a declaration of acceleration under the Indenture, but
before a judgment or decree for payment of the money due has been obtained by
the Trustee, the holders of a majority in aggregate principal amount of the
outstanding Notes, by written notice to us and the Trustee, may rescind such
declaration and its consequences if

          (1) we have paid or deposited with the Trustee a sum sufficient to pay

             (a) all overdue interest on all outstanding Notes,

             (b) all unpaid principal of and premium, if any, on any outstanding
        Notes that have become due otherwise than by such declaration of
        acceleration and interest thereon at the rate borne by the Notes,

             (c) to the extent that payment of such interest is lawful, interest
        upon overdue interest and overdue principal at the rate borne by the
        Notes,

             (d) all sums paid or advanced by the Trustee under the Indenture
        and the reasonable compensation, expenses, disbursements and advances of
        the Trustee, its agents and counsel; and

          (2) all Events of Default, other than the nonpayment of amounts of
     principal of, premium, if any, or interest on the Notes that has become due
     solely by such declaration of acceleration, have been cured or waived.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

     The holders of not less than a majority in aggregate principal amount of
the outstanding Notes may, on behalf of the holders of all the Notes, waive any
past defaults under the Indenture, except a default in the payment of the
premium of, if any, or interest on any Note, or in respect of a covenant or
provision which under the Indenture cannot be modified or amended without the
consent of the holder of each Note outstanding.

                                       80



<PAGE>

     If a Default or an Event of Default occurs and is continuing and is known
to the Trustee, the Trustee will mail to each holder of the Notes notice of the
Default or Event of Default within 30 days after the occurrence thereof. Except
in the case of a Default or an Event of Default in payment of principal of,
premium, if any, or interest on any Notes, the Trustee may withhold the notice
to the holders of such Notes if a committee of its trust officers in good faith
determines that withholding the notice is in the interests of the holders of the
Notes.

     We are required to furnish to the Trustee annual and quarterly statements
as to our performance of our obligations under the Indenture and as to any
default in such performance. We are also required to notify the Trustee within
five business days of the occurrence of any Default.

DEFEASANCE OR COVENANT DEFEASANCE OF THE INDENTURE

     We are entitled, at our option and at any time, to have our obligations
upon the Notes discharged with respect to the outstanding Notes ('defeasance').
Such defeasance means that we will be deemed to have paid and discharged the
entire Indebtedness represented by the outstanding Notes and to have satisfied
all of our other obligations under such Notes and the Indenture insofar as such
notes are concerned, except for

      the rights of holders of outstanding Notes to receive payments in respect
      of the principal of (and premium, if any, on) and interest on such Notes
      when such payments are due,

      our obligations to issue temporary Notes, register the transfer or
      exchange of any Notes, replace mutilated, destroyed, lost or stolen Notes,
      maintain an office or agency for payments in respect of the Notes and
      segregate and hold such payments in trust,

      the rights, powers, trusts, duties and immunities of the Trustee, and

      the defeasance provisions of the Indenture.

In addition, we are entitled, at our option and at any time, to have our
obligations released with respect to certain covenants set forth in the
Indenture, and any omission to comply with such obligations shall not constitute
a Default or an Event of Default with respect to the Notes ('covenant
defeasance').

     In order to exercise either defeasance or covenant defeasance,

          (1) we must irrevocably deposit or cause to be deposited with the
     Trustee, as trust funds in trust, specifically pledged as security for, and
     dedicated solely to, the benefit of the holders of the Notes, cash in
     United States dollars, or U.S. Government Obligations, or a combination
     thereof, in such amounts as will be sufficient, in the opinion of a
     nationally recognized firm of independent public accountants, or a
     nationally recognized investment banking firm, to pay and discharge the
     principal of (and premium, if any, on) and interest on the outstanding
     Notes at Stated Maturity (or upon redemption, if applicable) of such
     principal, premium, if any, or installment of interest;

          (2) no Default or Event of Default with respect to the Notes will have
     occurred and be continuing on the date of such deposit or, insofar as an
     event of bankruptcy under clause (8) of ' -- Events of Default' above is
     concerned, at any time during the period ending on the 91st day after the
     date of such deposit;

          (3) such defeasance or covenant defeasance shall not result in a
     breach or violation of, or constitute a default under, any material
     agreement or instrument (other than the Indenture) to which we are a party
     or by which we are bound;

          (4) in the case of defeasance, we shall have delivered to the Trustee
     an opinion of counsel in the United States stating that we have received
     from, or there has been published by, the Internal Revenue Service a
     ruling, or since the date of this offering memorandum, there has been a
     change in applicable federal income tax law, in either case to the effect,
     and based thereon such opinion shall confirm that, the holders of the
     outstanding Notes will not recognize income, gain or loss for federal
     income tax purposes as a result of such defeasance

                                       81



<PAGE>

     and will be subject to federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such defeasance
     had not occurred;

          (5) in the case of covenant defeasance, we shall have delivered to the
     Trustee an opinion of counsel in the United States to the effect that the
     holders of the outstanding Notes will not recognize income, gain or loss
     for federal income tax purposes as a result of such covenant defeasance and
     will be subject to federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such covenant
     defeasance had not occurred;

          (6) in the case of defeasance or covenant defeasance, we shall have
     delivered to the Trustee an opinion of counsel in the United States to the
     effect that after the 91st day following the deposit or after the date such
     opinion is delivered, the trust funds will not be subject to the effect of
     any applicable bankruptcy, insolvency, reorganization or similar laws
     affecting creditors' rights generally;

          (7) we shall have delivered to the Trustee an officers' certificate
     stating that we did not make the deposit with the intent of preferring the
     holders of the Notes over our other creditors with the intent of hindering,
     delaying or defrauding our other creditors; and

          (8) we shall have delivered to the Trustee an officers' certificate
     and an opinion of counsel, each stating that all conditions precedent
     provided for relating to either the defeasance or the covenant defeasance,
     as the case may be, have been complied with.

SATISFACTION AND DISCHARGE

     The Indenture will cease to be of further effect (except as to surviving
rights of registration of transfer or exchange of the Notes, as expressly
provided for in the Indenture) and the Trustee, at our expense, will execute
proper instruments acknowledging satisfaction and discharge of the Indenture
when

          (1) either

             (a) all the Notes previously authenticated and delivered (other
        than destroyed, lost or stolen notes which have been replaced or paid
        and Notes for whose payment money has been deposited in trust with the
        Trustee or any Paying Agent or segregated and held in trust by the
        Company and thereafter repaid to the Company or discharged from such
        trust as provided for in the Indenture) have been delivered to the
        Trustee for cancellation or

             (b) all Notes not previously delivered to the Trustee for
        cancellation (i) have become due and payable, (ii) will become due and
        payable at their Stated Maturity within one year or (iii) are to be
        called for redemption within one year under arrangements satisfactory to
        the Trustee for the giving of notice of redemption by the Trustee in our
        name, and at our expense, and we have irrevocably deposited or caused to
        be deposited with the Trustee as trust funds in trust for such purpose
        an amount sufficient to pay and discharge the entire Indebtedness on
        such Notes not previously delivered to the Trustee for cancellation, for
        principal of, premium, if any, and interest on the Notes to the date of
        such deposit (in the case of Notes which have become due and payable) or
        to the Stated Maturity or redemption date, as the case may be;

          (2) we have paid or caused to be paid all sums payable by us under the
     Indenture; and

          (3) we have delivered to the Trustee an officers' certificate and an
     opinion of counsel, each stating that all conditions precedent provided in
     the Indenture relating to the satisfaction and discharge of the Indenture
     have been complied with.

AMENDMENTS AND WAIVERS

     With certain exceptions, we and the Trustee may make modifications and
amendments of the Indenture and the Collateral Documents with the consent of the
holders of a majority in aggregate

                                       82



<PAGE>

outstanding principal amount of the Notes; provided, however, that no such
modification or amendment may, without the consent of the holder of each
outstanding Note affected thereby:

          (1) change the Stated Maturity of the principal of, or any installment
     of interest on, any Note, or reduce the principal thereof or the rate of
     interest thereon or any premium payable upon the redemption thereof, or
     change the coin or currency in which any Note or any premium or the
     interest thereon is payable, or impair the right to institute suit for the
     enforcement of any such payment after the Stated Maturity thereof (or, in
     the case of redemption, on or after the redemption date);

          (2) reduce the percentage in principal amount of outstanding Notes,
     the consent of whose holders is required for any such modification or
     amendment or the consent of whose holders is required for any waiver of
     compliance with certain provisions of, or certain defaults and their
     consequences provided for under, the Indenture;

          (3) modify any provisions described under ' -- Amendments and Waivers'
     or ' -- Events of Default,' except to increase the percentage of principal
     amount of outstanding Notes required for such actions or to provide that
     certain other provisions of the Indenture cannot be modified or waived
     without the consent of the holder of each outstanding Note;

          (4) amend, change or modify our obligation to make and consummate a

          (5) make any change in any of the provisions of the Collateral
     Documents not authorized by the Indenture, which materially adversely
     affect the holders of the Notes.

     Notwithstanding the foregoing, without the consent of any holder of Notes,
we and the Trustee are entitled to modify or amend the Indenture and the
Collateral Documents:

          (1) to evidence the succession of another Person to the Company or any
     other obligor on the Notes, and the assumption by any such successor of the
     covenants of the Company or such obligor in the Indenture, the Collateral
     Documents and in the Notes in accordance with the ' -- Consolidation,
     Merger and Sale of Assets' covenant;

          (2) to add to the covenants of the Company or any other obligor upon
     the Notes for the benefit of the holders of the Notes or to surrender any

     Notes, as applicable, in the Indenture, the Collateral Documents or in the
     Notes;

          (3) to cure any ambiguity, or to correct or supplement any provision
     in the Indenture, the Collateral Documents or the Notes which may be
     defective or inconsistent with any other provision in the Indenture, the
     Collateral Documents or the Notes or make any other provisions with respect
     to matters or questions arising under the Indenture or the Notes; provided,
     however, that, in each case, such provisions shall not adversely affect the
     interest of the holders of such Notes;

     required to be mortgaged, pledged or hypothecated, or in which a security
     interest is required to be granted to the Trustee pursuant to the Indenture
     or otherwise.

THE TRUSTEE

     The Indenture provides that, except during the continuance of an Event of
Default, the Trustee will perform only such duties as are specifically set forth
in the Indenture. If an Event of Default has occurred and is continuing, the
Trustee will exercise such rights and powers vested in it under the Indenture
and use the same degree of care and skill in its exercise as a prudent Person
would exercise under the circumstances in the conduct of such Person's own
affairs.

     The Indenture and the provisions of the Trust Indenture Act incorporated by
reference therein contain limitations on the rights of the Trustee thereunder,
should it become one of our creditors, to obtain payment of claims in certain
cases or to realize on certain property received by it in respect of any such
claims, as security or otherwise. The Trustee is permitted to engage in other
transactions; provided, however, that if it acquires any conflicting interest
(as defined in the Trust Indenture Act) it must eliminate such conflict or
resign.

GOVERNING LAW

     The Indenture, the Notes and the Collateral Documents will be governed by,
and construed in accordance with, the laws of the State of New York.

becoming a Restricted Subsidiary or such acquisition; provided, however, that,
for purposes of the 'Limitation on Indebtedness' covenant, such Indebtedness

from any Person or the date the acquired Person becomes a Restricted Subsidiary.

     'Adjusted Consolidated Operating Cash Flow' means Consolidated Operating

     transaction giving rise to the need to calculate 'Adjusted Consolidated

     Acquisition giving rise to the need to make such calculation as a result of
     the Company or a Restricted Subsidiary (including any Person who becomes a

     during the period commencing on the first day of such four fiscal quarter
     period to and including the Transaction Date (the 'Reference Period'), as
     if such Asset Sale or Asset Acquisition occurred on the first day of the
     Reference Period and

          (2) any incurrence or repayment, retirement or permanent reduction of
     any Indebtedness of the Company or any Restricted Subsidiary during the

relationship with a direct participant. The Depository Trust Company may hold
securities beneficially owned by other persons only through its participants and
the ownership interests and transfers of ownership interests of these other
persons will be recorded only on the records of the participants and not on the
records of The Depository Trust Company.

     The Depository Trust Company has also advised us that, in accordance with
its procedures, (1) upon deposit of the global notes, it will credit the
accounts of the direct participants with an interest in the global notes, and
(2) it will maintain records of the ownership interests of these direct
participants in the global notes and the transfer of ownership interests by and
between direct participants. The Depository Trust Company will not maintain
records of the ownership interests of, or the transfer of ownership interests by
and between, indirect participants or other owners of beneficial interests in
the global notes. Both direct and indirect participants must maintain their own
records of ownership interests of, and the transfer of ownership interests by
and between, indirect participants and other owners of beneficial interests in
the global notes.

     Investors in the global notes may hold their interests in the notes
directly through The Depository Trust Company if they are direct participants in
The Depository Trust Company or indirectly through organizations that are direct
participants in The Depository Trust Company. All interests in a global note may
be subject to the procedures and requirements of The Depository Trust Company.

     The laws of some states require that some persons take physical delivery in
definitive certificated form of the securities that they own. This may limit or
curtail the ability to transfer beneficial interests in a global note to these
persons. Because The Depository Trust Company can act only on behalf of direct
participants, which in turn act on behalf of indirect participants and others,
the ability of a person having a beneficial interest in a global note to pledge
its interest to persons or entities that are not direct participants in The
Depository Trust Company or to otherwise take actions in respect of its
interest, may be affected by the lack of physical certificates evidencing the
interests.

     Except as described below, owners of interests in the global notes will not
have notes registered in their names, will not receive physical delivery of
notes in certificated form and will not be considered the registered owners or
holders of these notes under the indenture for any purpose.

     Payments with respect to the principal of and interest on any notes
represented by a global note registered in the name of The Depository Trust
Company or its nominee on the applicable record date will be payable by the
trustee to or at the direction of The Depository Trust Company or its nominee in
its capacity as the registered holder of the global note representing these
notes under the indenture. Under the terms of the indenture, we and the trustee
will treat the person in whose names the notes are registered, including notes
represented by global notes, as the owners of the notes for the purpose of
receiving payments and for any and all other purposes whatsoever. Payments in
respect of the principal and interest on global notes registered in the name of
The Depository Trust Company or its nominee will be payable by the Trustee to
The Depository Trust Company or its nominee as the registered holder under the
indenture. Consequently, none of CD Radio, the Trustee or any of our agents, or
the trustee's agents has or will have any responsibility or liability for
(1) any aspect of The Depository Trust Company's records or any direct or
indirect participant's records relating to, or payments made on account of,
beneficial ownership interests in the global notes or for maintaining,
supervising or reviewing any of The Depository Trust Company's records or any
direct or indirect participant's records relating to the

                                      100



<PAGE>

beneficial ownership interests in any global note or (2) any other matter
relating to the actions and practices of The Depository Trust Company or any of
its direct or indirect participants.

     The Depository Trust Company has advised us that its current practice, upon
receipt of any payment in respect of securities such as the notes, including
principal and interest, is to credit the accounts of the relevant participants
with the payment on the payment date, in amounts proportionate to their
respective holdings in the principal amount of beneficial interest in the
security as shown on its records, unless it has reasons to believe that it will
not receive payment on the payment date. Payments by the direct and indirect
participants to the beneficial owners of interests in the global note will be
governed by standing instructions and customary practice and will be the
responsibility of the direct or indirect participants and will not be the
responsibility of The Depository Trust Company, the Trustee or us.

     Neither CD Radio nor the Trustee will be liable for any delay by The
Depository Trust Company or any direct or indirect participant in identifying
the beneficial owners of the notes and CD Radio and the Trustee may conclusively
rely on, and will be protected in relying on, instructions from The Depository
Trust Company for all purposes, including with respect to the registration and
delivery, and the respective principal amounts, of the notes.

     Transfers between participants in The Depository Trust Company will be
effected in accordance with The Depository Trust Company's procedures, and will
be settled in same day funds.

     The Depository Trust Company has advised us that it will take any action
permitted to be taken by a holder of notes only at the direction of one or more
participants to whose account The Depository Trust Company has credited the
interests in the global notes and only in respect of the portion of the
aggregate principal amount of the notes as to which the participant or
participants has or have given that direction. However, if there is an event of
default with respect to the notes, The Depository Trust Company reserves the
right to exchange the global notes for legended notes in certificated form and
to distribute them to its participants.

     Although The Depository Trust Company has agreed to these procedures to
facilitate transfers of interests in the global notes among participants in The
Depository Trust Company, it is under no obligation to perform or to continue to
perform these procedures and may discontinue them at any time. None of CD Radio,
the Trustee or any of our or the Trustee's respective agents will have any
responsibility for the performance by The Depository Trust Company and its
direct or indirect participants of their respective obligations under the rules
and procedures governing their operations.

EXCHANGE OF BOOK-ENTRY NOTES FOR CERTIFICATED NOTES

     A global note will be exchangeable for definitive notes in registered
certificated form if:

          (1) The Depository Trust Company notifies us that it is unwilling or
     unable to continue as depository for the global notes and we fail to
     appoint a successor depository within 90 days,

          (2) The Depository Trust Company ceases to be a clearing agency
     registered under the Exchange Act,

          (3) we elect to cause the issuance of the certificated notes upon a
     notice of the Trustee,

          (4) a default or event of default under the indenture for the notes
     has occurred and is continuing, or

          (5) a request to that effect is made but only upon prior written
     notice given to the Trustee by or on behalf of The Depository Trust Company
     in accordance with the indenture.

     In all cases, certificated notes delivered in exchange for any global note
or beneficial interests in a global note will be registered in the name, and
issued in any approved denominations, requested by or on behalf of The
Depository Trust Company, in accordance with its customary procedures.

                                      101



<PAGE>

EXCHANGE OF CERTIFICATED NOTES FOR BOOK-ENTRY NOTES

     Initial notes issued in certificated form may be exchanged for beneficial
interests in the global note.

SAME DAY SETTLEMENT

     We expect that the interests in the global notes will be eligible to trade
in The Depository Trust Company's Same-Day Funds Settlement System. As a result,
secondary market trading activity in these interests will settle in immediately
available funds, subject in all cases to the rules and procedures of The
Depository Trust Company and its participants. We expect that secondary trading
in any certificated notes will also be settled in immediately available funds.

PAYMENT

     The indenture requires that payments in respect of the notes represented by
global notes, including principal and interest, be made by wire transfer of
immediately available funds to the accounts specified by the holder of the
global notes. With respect to notes in certificated form, we will make all
payments of principal and interest on the notes at our office or agency
maintained for that purpose within the city and state of New York. This office
will initially be the office of the paying agent maintained for that purpose. At
our option however, we may make these installments of interest by (1) check
mailed to the holders of notes at their respective addresses provided in the
register of holder of notes or (2) transfer to an account located in the United
States maintained by the payee.

YEAR 2000

     The Depository Trust Company has advised us that its management is aware
that some computer applications, systems, and the like for processing data that
are dependent upon calendar dates, including dates before, on and after January
1, 2000, may encounter year 2000 problems. The Depository Trust Company has
informed its participants and other members of the financial community that it
has developed and is implementing a program so that its systems, as the same
relate to the timely payment of distributions, including principal and interest
payments, to security holders, book-entry deliveries and settlement of trades
within The Depository Trust Company, continue to function appropriately. This
program includes a technical assessment and a remediation plan, each of which is
complete. Additionally, The Depository Trust Company's plan includes a testing
phase, which is expected to be completed within the appropriate time frame.
However, The Depository Trust Company's ability to perform its services properly
is also dependent upon other parties, including issuers and their agents, as
well as third party vendors from whom The Depository Trust Company licenses
software and hardware, and third party vendors on whom The Depository Trust
Company relies for information or the provision of services, including
telecommunication and electrical utility service providers, among others. The
Depository Trust Company has informed its participants and other members of the
financial community that it is contacting and will continue to contact third
party vendors from whom The Depository Trust Company acquires services to:

      impress upon them the importance of these services being year 2000
      compliant, and

      determine the extent of their efforts for year 2000 remediation and, as
      appropriate, testing of their services.

     In addition, The Depository Trust Company is in the process of developing
contingency plans as it deems appropriate. According to The Depository Trust
Company, the above information with respect to The Depository Trust Company has
been provided to its participants and other members of the financial community
for informational purposes only and is not intended to serve as a
representation, warranty or contract modification of any kind.

                       DESCRIPTION OF OTHER INDEBTEDNESS

15% SENIOR SECURED DISCOUNT NOTES DUE 2007

     The senior secured discount notes were originally issued on November 27,
1997, will mature on December 1, 2007 and are secured by the Pledged Stock,
which pledge ranks equally with the pledge of the stock to secure CD Radio's
obligations in respect of the notes. The senior secured discount notes accrue
the original issue discount at a rate of 15% per annum until December 1, 2002,
and thereafter will bear interest at the same rate, payable in cash semiannually
in arrears. The senior secured discount notes indenture does not provide for a
sinking fund.

     The senior secured discount notes are not redeemable before December 1,
2002. Thereafter, the senior secured discount notes are redeemable, in whole or
in part, at our option, at the redemption prices described in the senior secured
discount notes indenture, plus accrued interest to the applicable redemption
date. Specifically, if redeemed during the 12-month period commencing on
December 1 of the years shown below, the redemption price will be that amount,
expressed as a percentage of the principal amount of the senior secured discount
notes, shown below:

<TABLE>

2005.....................................................    105.0%
2006.....................................................    102.5%
</TABLE>

     If there is a Change of Control (as defined in the senior secured discount
notes indenture) or asset sales in specific circumstances, we will be required
by the terms of the senior secured discount notes indenture to make an offer to
purchase the outstanding senior secured discount notes at a purchase price equal
to 101% of the accrued value of the senior secured discount notes, plus accrued
interest to the date of purchase.

     The indebtedness evidenced by the senior secured discount notes ranks
equally in right of payment with all of our other existing and future
unsubordinated indebtedness (including the notes we are offering) and senior in
right of payment to all of our existing and future obligations expressly
subordinated in right of payment to the senior secured discount notes.

     The senior secured discount notes indenture contains a number of covenants
restricting our operations and the operations of our subsidiaries, including
those restricting the incurrence of indebtedness; the making of restricted
payments (in the form of the declaration or payment of some kinds of dividends
or distributions, the purchase, redemption or other acquisition of any of our
capital stock, the voluntary prepayment of equal or subordinated indebtedness
and the making of some kinds of investments, loans and advances); transactions
with affiliates; the issuance of liens; sale-leaseback transactions; the
transfer of assets; issuances and sales of capital stock of subsidiaries; the
issuance of guarantees by subsidiaries; dividend and other payment restrictions
affecting subsidiaries; and consolidation, merger or sale of substantially all
of our assets.

     The events of default under the senior secured discount notes indenture
include provisions that are typical of senior debt financings, including a
cross-acceleration to a default by CD Radio or any material subsidiary on any
indebtedness that has an aggregate principal amount in excess of $5 million.
Upon the occurrence of an event of default, the trustee or the holders of not
less than 25% in principal amount at maturity of the outstanding senior secured
discount notes may immediately accelerate the maturity of all the senior secured
discount notes as provided in the senior secured discount notes indenture.

VENDOR FINANCING

     Pursuant to the Tranche A Facility, Bank of America and other financial
institutions have committed to provide us a term loan facility in the aggregate
principal amount of up to $115 million. The proceeds of the loans are being used
by us to fund a portion of the progress

                                      103



<PAGE>

payments required to be made under the Loral Satellite Contract for the purchase
of launch services and to pay interest, fees and other expenses related to the
Tranche A Facility. The loans are due on the earlier of February 29, 2000 and
ten days before the launch of our second satellite and bear interest, at our
option, at either (1) the London Interbank Offered Rate plus 1.75% or (2) the
higher of (a) the rate publicly announced by Bank of America as its reference
rate and (b) 0.50% per annum above the Federal Funds Rate then in effect. The
loans are secured by the grant of a security interest in the portion of the
Loral Satellite Contract relating to launch services. The Tranche A Facility
also contains covenants relating to financial information, the conduct of our
business, payments under the Loral Satellite Contract, maintenance of
governmental and other approvals, maintenance of existence and qualifications,
maintenance of books and records, maintenance of property and insurance,
compliance with laws and notice of defaults. In addition, the terms of the
Tranche A Facility require us to maintain a minimum net worth and sufficient
cash. As of June 30, 1999, we had borrowed $95.5 million under the Tranche A
Facility, substantially all of which was used to make progress payments under
the Loral Satellite Contract.

     Loral assisted us in arranging the Tranche A Facility. Specifically, Loral
has agreed that at maturity of the loans (including maturity as a result of an
acceleration), upon the occurrence of a bankruptcy of CD Radio or upon the
occurrence of an event of default by Loral Space under its agreement with Bank
of America, Loral Space & Communications Ltd. will repurchase from Bank of
America and the other Lenders the loans at a price equal the principal amount of
the loans plus accrued and unpaid interest. In exchange for providing this
credit support, we pay Loral Space & Communications Ltd. a fee equal to 1.25%
per annum of the outstanding amount of the loans from time to time.

CONVERTIBLE SUBORDINATED NOTES DUE 2009

     On September 29, 1999, we issued $125 million aggregate principal amount of
our 8 3/4% Convertible Subordinated Notes due 2009 in an underwritten public
offering and on October 6, 1999, we issued an additional $18.75 million
aggregate principal amount of these notes in connection with the exercise of an
over-allotment option granted to the underwriters of this offering. These sales
raised approximately $137 million in net proceeds.

     The convertible subordinated notes are unsecured obligations, will mature
on September 29, 2009 and are subordinated to our existing and future senior
indebtedness. The convertible subordinated notes bear interest at the rate of
8 3/4% per annum on the principal amount, payable semi-annually on March 29 and
September 29 of each year, commencing on March 29, 2000, to holders of record at
the close of business on March 14 or September 14 (whether or not a business
day) immediately preceding each interest payment date. We currently expect to
fund interest payments through proceeds from the issuance of common stock.

     The convertible subordinated notes are convertible at any time prior to
their stated maturity into shares of our common stock at a conversion rate of
35.134 shares per $1,000 principal amount (equivalent to a conversion price of
$28.4625 per share of common stock), subject to adjustment upon the occurrence
of certain events.

     There is no sinking fund for the convertible subordinated notes. We may not
redeem the convertible subordinated notes at our option prior to September 29,
2002. On and after that date, we may redeem the convertible subordinated notes,
in whole or in part, on not less than 30 days' notice at specified redemption
prices, beginning at 106.125% of their principal amount during the 12-month
period commencing September 29, 2002 and at declining percentages of their
principal amount thereafter. We may exercise this option to redeem these notes
only if the last reported sale price for our common stock is at least 150% of
the conversion price for at least 20 trading days within a period of 30
consecutive days ending within five trading days of the call for redemption.

                                      104



<PAGE>

     In the event of a change in control (as defined in the first supplemental
indenture relating to the convertible subordinated notes), we will be required
to offer to purchase all the convertible subordinated notes for cash at a price
of 100% of the principal amount of each holder's notes.

     The indenture and the first supplemental indenture for the convertible
subordinated notes include customary covenants, events of default and other
provisions (including provisions for amendment, modification and discharge of
our obligations).

     U.S. Trust Company of Texas, N.A. is the trustee under the indenture and
the first supplemental indenture for the convertible subordinated notes.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following discussion summarizes some of the United States federal
income tax consequences that may be relevant to the exchange of initial notes
for exchange notes in accordance with the exchange offer, and the purchase of,
ownership and disposition of the exchange notes. The discussion is intended only
as a summary and does not purport to be a complete analysis or listing of all
potential tax considerations that may be relevant to holders of exchange notes.
The discussion does not include special rules that may apply to some holders
(including insurance companies, tax-exempt organizations, financial institutions
or broker-dealers, holders whose functional currency is not the United States
dollar, and persons holding the notes as part of a 'straddle,' 'hedge,'
'constructive sale' or 'conversion transaction,' and investors who are not
United States Persons), and does not address the tax consequences of the law of
any state, locality or foreign jurisdiction. The discussion is based upon
currently existing provisions of the Internal Revenue Code of 1986 (the
'Internal Revenue Code'), existing and proposed Treasury regulations under the
Internal Revenue Code and current administrative rulings and court decisions.
Everything listed in the previous sentence may change and any change could
affect the continuing validity of this discussion. The discussion below assumes
that the initial notes or exchange notes, as applicable, are held as capital
assets within the meaning of Section 1221 of the Internal Revenue Code.

     As used in this prospectus, 'United States Person' means a beneficial owner
of the notes who or that (1) is a citizen or resident of the United States, (2)
is a corporation, partnership or other entity created or organized in or under
the laws of the United States or political subdivision of the United States, (3)
is an estate the income of which is subject to U.S. federal income taxation
regardless of its source, (4) is a trust if (A) a U.S. court is able to exercise
primary supervision over the administration of the trust and (B) one or more
U.S. fiduciaries have authority to control all substantial decisions of the
trust, or (5) is otherwise subject to U.S. federal income tax on a net income
basis in respect of the notes.

     THE FOLLOWING DISCUSSION IS FOR GENERAL INFORMATION ONLY. THE TAX TREATMENT
MAY VARY DEPENDING UPON A HOLDER'S PARTICULAR SITUATION. HOLDERS SHOULD CONSULT
THEIR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE
EXCHANGE OFFER AND THE OWNERSHIP OF THE INITIAL NOTES OR THE EXCHANGE NOTES,
INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS.

TAXATION OF HOLDERS ON EXCHANGE

     The exchange of initial notes for exchange notes in accordance with the
exchange offer will not be treated as an exchange or otherwise as a taxable
event to holders. Consequently, (1) no gain or loss will be realized by a holder
upon receipt of an exchange note, (2) the holding period of the exchange note
will include the holding period of the initial note exchanged for the exchange
note and (3) the adjusted tax basis of the exchange note will be the same as the
adjusted tax basis of the initial note exchanged for the exchange note
immediately before the exchange. Further, the tax consequences of ownership and
disposition of any exchange note should be the same as the tax consequences of
ownership and disposition of an initial note.

STATED INTEREST AND ORIGINAL ISSUE DISCOUNT

     A holder of an exchange note will be required (absent the election
described below to treat all interest on the note as original issue discount
('OID') within the meaning of Section 1273(a) of the Internal Revenue Code) to
report as income for U.S. federal income tax purposes the portion of the stated
interest on the note that is 'qualified stated interest' ('QSI') in accordance
with the holder's method of accounting for tax purposes. QSI on a note is the
stated interest that is unconditionally payable at least annually at a single
fixed rate.

     The exchange notes will have original issue discount for U.S. federal
income tax purposes. The amount of original issue discount on an exchange note
is the excess of its 'stated redemption price

                                      106



<PAGE>

at maturity' (the sum of all payments to be made on the note other than QSI,
whether denominated as interest or principal) over its 'issue price.' Because
the exchange notes are treated for federal income tax purposes as if they were
the same as the initial notes, the amount of OID on an exchange note will be
calculated as if the exchange note and the initial note were a single note that
was issued at the time the initial note was issued, for an issue price equal to
the issue price of the initial note, and any accrued OID on the initial note at
the time of the exchange offer will carry over and be treated as accrued OID on
the exchange notes. The issue price of each initial note is $843.09, which is
the amount of the unit price that CD Radio allocated to the initial notes at the
time of the issuance of the units. See ' -- The Units.' Each holder of exchange
notes (whether a cash or accrual method taxpayer) will be required to include in
income OID as it accrues, in advance of the receipt of some or all of the
related cash payments.

     The amount of OID includable in income by the holder of an exchange note is
the sum of the 'daily portions' of OID with respect to the note for each day
during the taxable year or portion of the taxable year on which the holder held
the note ('accrued OID'). The daily portion is determined by allocating to each
day in any 'accrual period' a proportionate portion of the OID allocable to that
accrual period. The accrual periods for a note will be periods that are each
selected by the holder of the note that are no longer than one year, provided
that each scheduled payment occurs either on the final day of an accrual period
or on the first day of an accrual period. The amount of OID allocable to any
accrual period other than the initial short accrual period (if any) and the
final accrual period is an amount equal to the excess of (a) the product of the
note's 'adjusted issue price' at the beginning of the accrual period and its
yield to maturity (determined on the basis of compounding at the close of each
accrual period and properly adjusted for the length of the accrual period) over
(b) the sum of any payments of QSI allocable to the accrual period. The amount
of OID allocable to the final accrual period is the difference between the
amount payable at maturity (other than a payment of QSI) and the adjusted issue
price of the note at the beginning of the final accrual period. The amount of
OID allocable to any initial short accrual period may generally be computed
under any reasonable method. The 'yield to maturity' is the discount rate that,
when used in computing the present value of all payments to be made under the
notes, produces an amount equal to the issue price of the notes. The 'adjusted
issue price' of the note at the start of any accrual period is equal to its
issue price increased by the accrued OID for each prior accrual period and
reduced by any prior payments with respect to the note that were not QSI
payments. We are required to report the amount of OID accrued on exchange notes
held of record by persons other than corporations and other exempt holders of
notes, which may be based on accrual periods other than those chosen by the
holders of notes.

     A holder of a note, with some limitations, may elect to include in gross
income for U.S. federal income tax purposes all interest that accrues on the
note by using the constant yield method described above. For purposes of the
election, interest includes all stated and unstated interest, acquisition
discount, OID, de minimis OID, market discount, and de minimis market discount,
as adjusted by any amortizable bond premium or acquisition premium (as discussed
below). In applying the constant yield method to a note with respect to which an
election is made, the issue price of the note will equal the electing holder's
adjusted basis in the note immediately after its acquisition, the issue date of
the note will be the date of its acquisition, and no payments on the note will
be treated as payments of QSI. This election is generally applicable only to the
note with respect to which it is made and may not be revoked without the consent
of the Internal Revenue Service. This election, if made in respect of a market
discount bond, will be treated as an election to include market discount in
income currently on all market discount bonds held by the holder during or after
the taxable year in which the note is acquired. See the discussion below under
'Market Discount.' If the election is made with respect to a note with
amortizable bond premium, the holder will be deemed to have elected to apply
amortizable bond premium against interest with respect to all debt instruments
with amortizable bond premium held by the electing holder during or after the
taxable year in which the note is acquired. See the discussion below under
'Acquisition Premium and Amortizable Bond Premium.'

                                      107



<PAGE>

     The tax basis of an exchange note in the hands of the holder of the note
will be increased by the amount of OID, if any, on the note that is included in
the holder's income under these rules, and will be decreased by the amount of
any payments (other than payments of QSI) made with respect to the note.

     Applicable High Yield Discount Obligation. If the exchange notes are
treated as having 'significant original issue discount,' the notes will be
subject to the applicable high yield discount obligation ('AHYDO') rules of the
Internal Revenue Code. The notes will have 'significant original issue discount'
if the amount includible in gross income of a holder for periods before the
close of any accrual period ending after the date 5 years after the date of
issue exceeds the sum of (1) the aggregate cash interest paid before the close
of such accrual period and (2) the product of the issue price of the note and
its yield to maturity. If the notes are determined to be subject to the AHYDO
rules, our deductions with respect to original issue discount will be suspended
until these amounts are actually paid, and the 'disqualified portion' of the
original issue discount (defined as the portion that is attributable to the
yield on such note in excess of the applicable federal rate plus 600 basis
points) will be permanently nondeductible. These rules generally do not affect
the amount, timing or character of a holder's income; however, domestic
corporate holders may be eligible for a dividends-received deduction with
respect to their inclusion in income of the 'disqualified portion' if this
amount, if paid with respect to stock, would have been a dividend (i.e., would
have been out of earnings and profits). The availability of the
dividends-received deduction is subject to a number of complex limitations.

     Market Discount. If an exchange note is acquired by a subsequent purchaser
at a 'market discount,' some or all of any gain realized upon a disposition
(including a sale or a taxable exchange) or payment at maturity of the note may
be treated as ordinary income. 'Market discount' with respect to a security is,
subject to a de minimis exception, the excess of (1) the issue price of the
security increased by all previously accrued original issue discount and
probably reduced (although the Internal Revenue Code does not expressly so
provide) by any cash payments in respect of the security over (2) the holder's
initial tax basis in the security. The amount of market discount treated as
having accrued will be determined either on a ratable basis, or, if the holder
so elects, on a constant interest method. Upon any subsequent disposition
(including a gift or payment at maturity) of the note (other than in connection
with some nonrecognition transactions), the lesser of any gain on the
disposition (or appreciation, in the case of a gift) or the portion of the
market discount that accrued while the note was held by the holder will be
treated as ordinary interest income at the time of the disposition. Instead of
including accrued market discount in income at the time of disposition, a holder
may elect to include market discount in income currently. Unless a holder so
elects, the holder may be required to defer a portion of any interest expense
that may otherwise be deductible on any indebtedness incurred or maintained to
purchase or carry the note until the holder disposes of the note. The election
to include market discount in income currently, once made, is irrevocable and
applies to all market discount obligations acquired on or after the first day of
the first taxable year to which the election applies and may not be revoked
without the consent of the Internal Revenue Service.

     Acquisition Premium. If a subsequent holder's tax basis in an exchange note
(1) exceeds the adjusted issue price of the note, and (2) is less than or equal
to the stated redemption price at maturity (reduced by any payments made on the
note other than payments of QSI), the excess will be considered 'acquisition
premium.' The holder is permitted to reduce the amount of OID required to be
included in gross income by an amount equal to the OID otherwise includible
multiplied by a fraction, the numerator of which is the amount of acquisition
premium and the denominator of which is the excess of the sum of all amounts
payable on the notes after the purchase date (other than QSI payments) over the
adjusted issue price. Alternatively, a holder may elect to amortize acquisition
premium on a constant yield basis, treating the holder's purchase price as the
note's issue price.

     Bond Premium. If a subsequent holder's tax basis in an exchange note
exceeds the sum of all amounts (other than QSI) payable on the note after the
acquisition date, the excess would be treated as 'amortizable bond premium.' The
holder may elect to amortize the excess over the period from the acquisition
date of the note to the maturity date. Amortizable bond premium

                                      108



<PAGE>

allocable to a period may be offset against QSI on the related security to the
extent QSI for the period exceeds the holder's yield for the period (the yield
being the discount rate that, when used in computing the present value of all
remaining payments to be made (including QSI), produces an amount equal to the
holder's basis in the note). Additional amortizable premium for a period may be
treated as a bond premium deduction to the extent that the holder's total
interest inclusions on the note in prior periods exceed the total amount treated
by the holder as a bond premium deduction on the note in prior periods. Any
excess over the total interest inclusions is carried forward to the next accrual
period. A holder that elects to amortize bond premium must reduce its adjusted
basis in the note by the amount of allowable amortization. An election to
amortize bond premium applies to the amortizable bond premium on all taxable
bonds held during or after the holder's taxable year for which the election is
made and may be revoked only with the consent of the Internal Revenue Service.

     Disposition of Notes. A holder of exchange notes will recognize gain or
loss upon the sale, redemption, retirement or other disposition of notes; this
gain or loss will generally be equal to the difference between (1) the amount of
cash and the fair market value of property received and (2) the holder's
adjusted tax basis (including any accrued OID or market discount previously
included in income by the holder and reduced by any previous payments (other
than payments of QSI) with respect to the notes and any amortizable bond premium
applied to reduce interest on the notes). Subject to the market discount rules
discussed above, gain or loss recognized will be capital gain or loss and will
be long term capital gain or loss if the holder has held the notes (or is
treated as having held the notes) for longer than one year. Net capital gains of
individuals are subject to tax at lower rates than items of ordinary income. The
deductibility of capital losses is subject to limitations.

     Reporting Requirements. We will provide annual information statements to
holders of the exchange notes and to the Internal Revenue Service, setting forth
the amount of original issue discount and QSI determined to be attributable to
the notes for that year.

BACKUP WITHHOLDING

     Under some circumstances, the failure of a holder of exchange notes to
provide sufficient information to establish that the holder is exempt from the
backup withholding provisions of the Internal Revenue Code will subject the
holder to backup withholding at a rate of 31 percent on payments of principal
and interest on the notes, and the proceeds from a disposition of the exchange
notes. In general, backup withholding applies if a noncorporate holder fails to
furnish a correct taxpayer identification number, fails to report dividend and
interest income in full, or fails to certify that the holder has provided a
correct taxpayer identification number and that the holder is not subject to
withholding. An individual's taxpayer identification number is the individual's
Social Security number. Any amount withheld from a payment to a holder under the
backup withholding rules will be allowed as a credit against the holder's U.S.
federal income tax liability and may entitle the holder to a refund, provided
the required information is furnished to the Internal Revenue Service.

     THE ABOVE SUMMARY DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION
THAT MAY BE RELEVANT TO A PARTICULAR HOLDER OF EXCHANGE NOTES OR INITIAL NOTES
IN LIGHT OF HIS OR HER PARTICULAR CIRCUMSTANCES AND INCOME TAX SITUATION. EACH
HOLDER OF NOTES SHOULD CONSULT THEIR TAX ADVISOR AS TO THE SPECIFIC TAX
CONSEQUENCES TO THE HOLDER OF THE EXCHANGE OFFER AND THE OWNERSHIP OF THE
INITIAL NOTES OR THE EXCHANGE NOTES, INCLUDING THE APPLICATION AND EFFECT OF
STATE, LOCAL, FOREIGN AND OTHER TAX LAWS, OR SUBSEQUENT REVISIONS OF THESE TAX
LAWS.

                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives exchange notes for its own account
pursuant to the exchange offer in exchange for initial notes acquired by such
broker-dealer as a result of market making or other trading activities may be
deemed to be an 'underwriter' within the meaning of the

                                      109



<PAGE>

Securities Act and, therefore, must deliver a prospectus meeting the
requirements of the Securities Act in connection with any resales, offers to
resell or other transfers of the exchange notes received by it in connection
with the exchange offer. Accordingly, each such broker-dealer must acknowledge
that it will deliver a prospectus meeting the requirements of the Securities Act
in connection with any resale of such exchange notes. The letter of transmittal
states that by acknowledging that it will deliver and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
'underwriter' within the meaning of the Securities Act. This prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-
dealer in connection with resales of exchange notes received in exchange for
initial notes where such initial notes were acquired as a result of
market-making activities or other trading activities.

     We will not receive any proceeds from any sale of exchange notes by
broker-dealers. Exchange notes received by broker-dealers for their own account
pursuant to the exchange offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the exchange notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such exchange notes. Any
broker-dealer that resells exchange notes that were received by it for its own
account pursuant to the exchange offer and any broker or dealer that
participates in a distribution of such exchange notes may be deemed to be an
'underwriter' within the meaning of the Securities Act and any profit of any
such resale of exchange notes and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act. The letter of transmittal states that by acknowledging that it will deliver
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an 'underwriter' within the meaning of the Securities Act.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders
CD RADIO INC.:

     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, stockholders' equity and cash
flows present fairly, in all material respects, the financial position of CD
Radio Inc. and subsidiary (a Development Stage Enterprise) (collectively, the
'Company') at December 31, 1998 and 1997, and the results of its operations and
its cash flows for each of the three years in the period ended December 31,
1998, and for the period May 17, 1990 (the date of inception) to December 31,
1998, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

     The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 2 to the
financial statements, the Company is expected to incur significant operating
losses before it commences operations and is obligated to make substantial
capital expenditures through December 31, 1999 for which it currently does not
have the financial resources. This raises substantial doubt about its ability to
continue as a going concern. Management's plans in regard to this matter are
also described in Note 2. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

                          CD RADIO INC. AND SUBSIDIARY
                        (A DEVELOPMENT STAGE ENTERPRISE)

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS

     CD Radio Inc. (the 'Company'), a Delaware corporation, is a pioneer in the
development of a service for broadcasting digital quality music programming via
satellites to subscribers' vehicles ('satellite radio'). The Company intends to
focus exclusively on providing a consumer service, and anticipates that the
equipment required to receive its broadcasting will be manufactured by consumer
electronics manufacturers. In April 1997, the Company was the winning bidder in
an FCC auction for one of two national satellite broadcast licenses with a
winning bid of $83.3 million. The Company paid the bid amount during 1997 and
was awarded an FCC license on October 10, 1997.

2. ACCOUNTING POLICIES

     Basis of presentation: The consolidated financial statements include the
accounts of CD Radio Inc. and its wholly owned subsidiary. Intercompany
transactions are eliminated in consolidation. The Company's principal activities
to date have included technology development, obtaining regulatory approval for
the CD Radio service, commencement of construction of three satellites,
acquisition of content for its programming, strategic planning, market research,
recruitment of its senior management team and securing financing for working
capital and capital expenditures. Accordingly, the Company's financial
statements are presented as those of a development stage enterprise, as
prescribed by Statement of Financial Accounting Standards ('SFAS') No. 7,
'Accounting and Reporting by Development Stage Enterprises.'

     The Company's financial statements for the year ended December 31, 1998
have been prepared on a going concern basis which contemplates the realization
of assets and the settlement of liabilities and commitments in the normal course
of business. The Company expects to incur additional substantial expenditures to
complete the construction of its satellite system, to plan and implement its
service and to sustain its operations until it generates positive cash flow from
operations. The Company's working capital at December 31, 1998 will not be
sufficient to meet these objectives as presently structured. Management
recognizes that it must generate additional resources or consider modifications
to its programs to enable it to continue operations with its available
resources. Management's plans to raise additional financing include the sale of
debt or equity securities or a combination thereof. Management expects to
complete the sale of such securities, however, no assurance can be given that
such financings will be completed on terms acceptable to the Company. If the
Company is unable to obtain additional financing, management will be required to
sharply curtail its satellite program and to curtail its operations. The
financial statements do not include any adjustments relating to the
recoverability of assets and classification of liabilities that might be
necessary should the Company be unable to continue as a going concern.

     Risks and uncertainties: As a development stage enterprise, the Company has
a limited operating history and its prospects are subject to the risks, expenses
and uncertainties frequently encountered by companies in new and rapidly
evolving markets for satellite products and services. These risks include the
failure of the Company to have: (1) a successful and timely construction and
deployment of its satellite system; (2) the development and manufacture by one
or more consumer electronics manufacturers of devices capable of receiving CD
Radio broadcasts and antennas; and (3) the successful marketing and consumer
acceptance of the Company's service, as well as other risks and uncertainties.

     Use of estimates: The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities at the date of the financial statements and the reported amounts of
expenses during the reported period. The estimates involve judgments with
respect to,

                                      F-9

                        (A DEVELOPMENT STAGE ENTERPRISE)

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

among other things, various future factors which are difficult to predict and
are beyond the control of the Company. Actual amounts could differ from these
estimates.

     Cash equivalents: The Company considers all highly liquid investments
purchased with an original maturity of three months or less to be cash
equivalents.

     Concentration of credit risk: The Company has invested its excess cash in
obligations of agencies of the U.S. government and in commercial paper issued by
major U.S. corporations with high credit ratings. The Company has not
experienced any losses on its investments.

     Property and equipment: All costs incurred related to activities necessary
to prepare the CD Radio satellite system for use are capitalized, including
interest on funds borrowed to finance construction. To date, such costs consist
of satellite construction in process, launch construction in process, broadcast
studio construction in process, terrestrial repeater network in process,
capitalized interest (totaling $16.2 million at December 31, 1998) and the cost
to acquire the FCC license at auction. Charges to operations for depreciation
and amortization of these items will begin upon commencement of commercial
broadcasting, which is projected to be in 2000. The Company anticipates that it
will depreciate satellite and launch costs over a period not to exceed 15 years
and amortize the FCC license costs over 40 years. Depreciation of technical and
other equipment, primarily satellite communications equipment, is computed on
the straight-line method based on estimated useful lives ranging from 4 to 10
years.

     Long-lived assets: The Company evaluates the recoverability of long-lived
assets, utilizing qualitative and quantitative factors. At such time as an
impairment in value is identified, the impairment, will be quantatively measured
in accordance with SFAS No. 121, 'Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be disposed of,' and charged to operations.
No such impairment losses have been recognized to date.

     Fair value information: The carrying amount of current assets and current
liabilities approximates fair value because of the short maturity of these
investments. The fair value of fixed-rate long-term debt and redeemable
preferred stock is estimated using quoted market prices where applicable or by
discounting remaining cash flows at the current market rate.

     Income taxes: Deferred income taxes are recognized for the tax consequences
in future years of differences between the tax bases of assets and liabilities
and their financial reporting amounts at each year-end, based on enacted tax
laws and statutory tax rates applicable to the periods in which the differences
are expected to affect taxable income. Valuation allowances are established when
necessary to reduce deferred tax assets to the amount expected to be realized.
Income tax expense is the sum of tax payable for the period and the change
during the period in deferred tax assets and liabilities.

     Redeemable convertible preferred stock: The Company records redeemable
convertible preferred stock on the date of issuance by allocating a portion of
the proceeds that represents a beneficial conversion feature to additional
paid-in capital. The beneficial conversion feature (discount) is amortized using
the effective interest method and is recognized as a deemed dividend over the
shortest period of conversion. The carrying value of the stock accretes to its
liquidation value over the mandatory redemption period. The periodic accretion
increases the net loss applicable to common stockholders.

     Net loss per share: Effective December 31, 1997, the Company adopted SFAS
No. 128, 'Earnings Per Share,' which requires the presentation of basic earnings
(loss) per share and diluted earnings per share. Basic earnings (loss) per share
is based on the weighted average number of outstanding shares of common stock.
Diluted earnings per share adjusts the weighted average for the potential
dilution that could occur if stock options, warrants or other convertible
securities were exercised or converted into common stock. Diluted earnings
(loss) per share is the

same as basic earnings per share because the effects of such items were
anti-dilutive. Earnings (loss) per share for all periods presented conform to
SFAS No. 128.

preferred stock dividend requirements to net loss per share applicable to common
stockholders:

     Comprehensive income: In 1997, the Financial Accounting Standards Board
('the FASB') issued SFAS No. 130, 'Reporting Comprehensive Income.' SFAS No. 130
requires additional reporting with respect to certain changes in assets and
liabilities that previously were included in stockholders' equity. Presently,
the Company has no comprehensive income items to report.

     Recent accounting pronouncements: The FASB has issued SFAS No. 131,
'Disclosures about Segments of an Enterprise and Related Information,' which
requires financial and descriptive information with respect to operating
segments of an entity based on the way management disaggregates the entity for
internal operating decisions. There is no impact to the Company's 1998 financial
statements from the adoption of this standard.

     Reclassifications: Certain amounts in the prior year's financial statements
have been reclassified to conform to the current presentation.

3. MARKETABLE SECURITIES

     Marketable securities consist of fixed income securities and are stated at
market value. Marketable securities are defined as trading securities under the
provision of SFAS No. 115, 'Accounting for Certain Investments in Debt and
Equity Securities' and unrealized holding gains and losses are reflected in
earnings. Unrealized holding gains were $624,000 and $232,000 at December 31,
1997 and 1998, respectively.

   LONG-TERM

     In November 1997, the Company received net proceeds of $116 million from
the issuance of 12,910 units consisting of $20,000 principal amount at maturity
of 15% Senior Secured Discount Notes due 2007 (the 'Notes') and a warrant to
purchase an additional $3,000 principal amount at maturity of Notes for no
additional consideration. All of the warrants were exercised in 1997. The
aggregate maturity value of the Notes, including Notes issued upon the exercise
of the warrants, is $297 million. The Notes mature on December 1, 2007 and the
first cash interest payment is deferred until June 2003. Cash interest of $22.3
million will be due on each June 1 and December 1 of the remaining years of the
Notes. The Indenture under which the Notes were issued contains various
restrictive covenants, including a limitation on the amount of additional
indebtedness that may be incurred by the Company. As of December 31, 1997 and
1998, the Company had accrued interest relating to the Notes of $1,869,000 and
$27,867,000, respectively. At December 31, 1998, the Notes had a fair value of
$157 million. The Notes are redeemable, at the option of the Company, in whole
or in part, at any time on or after December 1, 2002, at specified redemption
prices plus accrued interest, if any, to the date of redemption. The Notes are
senior obligations of the Company and are secured by a lien on all of the issued
and outstanding common stock of Satellite CD Radio, Inc. ('SCDR'). SCDR conducts
no business activities and its only asset is the FCC license.

     The Company incurred $8.7 million of costs in connection with the issuance
of the Notes. Debt issuance costs have been deferred and are amortized over the
10 year life of the Notes. Accumulated amortization of debt issuance costs was
$73,000 and $952,000 at December 31, 1997 and 1998, respectively.

5. DEFERRED SATELLITE PAYMENTS

     Under an amended and restated contract (the 'Loral Satellite Contract')
with Space Systems/Loral, Inc. ('SS/L'), SS/L has agreed to defer certain
amounts due under the Loral Satellite Contract. The amounts deferred, which
approximate fair value, bear interest at 10% per year and are due in quarterly
installments beginning in June 2002. The Company has the right to prepay any
deferred payments together with accrued interest, without penalty.

   PREFERRED STOCK

     In April 1997, the Company completed a private placement of its 5% Delayed
Convertible Preferred Stock (the '5% Preferred Stock'). The Company sold a total
of 5.4 million shares of the 5% Preferred Stock for an aggregate sales price of
$135 million. The 5% Preferred Stock was immediately convertible at a discount
to the fair market value of Common Stock and accordingly, the Company recorded
approximately $52 million as a deemed dividend in determining net loss
attributable to common stockholders.

     In November 1997, the Company exchanged 1,846,799 shares of 10 1/2% Series
C Convertible Preferred Stock (the '10 1/2% Preferred Stock') for all
outstanding shares of its 5% Preferred Stock. Each share of 10 1/2% Preferred
Stock is convertible into a number of shares of Common Stock calculated by
dividing the $100 per share liquidation preference (the 'Liquidation
Preference') by a conversion price of $18.00. This conversion price is subject
to adjustment for certain corporate events. Any stockholder who converts the
10 1/2% Preferred Stock into Common Stock prior to November 15, 2002 will
forfeit the right to any accrued and unpaid dividends. Dividends on the 10 1/2%
Preferred Stock are cumulative from the date of issuance and payable, if
declared by the Board of Directors, on a quarterly basis commencing on November
15, 2002. Dividends may be paid with cash or Common Stock at the option of the
Company. Commencing November 15, 1999, the Company may redeem the 10 1/2%
Preferred Stock at the Liquidation Preference plus any accrued and unpaid
dividends, provided the price of the Company's Common Stock is at least $31.50
per share during a specified period. After November 15, 2002, the Company's
right to redeem the 10 1/2% Preferred Stock is not restricted by the market
price of its Common Stock. The Company is required to redeem all outstanding
shares of 10 1/2% Preferred Stock on November 15, 2012 at a price equal to the
Liquidation Preference plus any accrued and unpaid dividends. As of December 31,
1997 and 1998, the Company accrued dividends payable relating to the 10 1/2%
Preferred Stock totaling $2,338,000 and $18,179,000, respectively. At
December 31, 1998, the 10 1/2% Preferred Stock had a fair value of $279 million.

     On December 23, 1998, the Company and Apollo Investment Fund IV, L.P., a
Delaware limited partnership ('AIF IV'), and Apollo Overseas Partners IV, L.P.,
a Cayman Islands limited partnership ('AOP IV' and, together with AIF IV, the
'Apollo Investors') completed a transaction pursuant to which the Company sold
to the Apollo Investors 1,350,000 shares of its 9.2% Series A Junior Cumulative
Convertible Preferred Stock, par value $.001 per share (the 'Series A Preferred
Stock'), for an aggregate purchase price of $135 million. Each share of Series A
Preferred Stock is convertible into a number of shares of Common Stock
calculated by dividing the $100 per share liquidation preference (the 'Series A
Liquidation Preference') by a conversion price of $30. This conversion price is
subject to adjustment for certain corporate events. Dividends on the Series A
Preferred Stock are payable annually commencing on November 15, 1999 and may be
paid with cash or additional shares of Series A Preferred Stock, at the option
of the Company. From and after November 15, 2001 and prior to November 15, 2003,
the Company may redeem the Series A Preferred Stock at the Series A Liquidation
Preference, plus any unpaid dividends, provided the price of the Common Stock is
at least $60 per share during a specified period. From and after November 15,
2003, the Company's right to redeem the Series A Preferred Stock is not
restricted by the market price of its Common Stock. The Company is required to
redeem all outstanding shares of the Series A Preferred Stock at a price equal
to the Series A Liquidation Preference plus any unpaid dividends on November 15,
2011. On the date of issuance, the Series A Preferred Stock was immediately
convertible at a discount to the then fair market value of the Common Stock and,
accordingly, the Company recorded approximately $11 million as a deemed dividend
in net loss applicable to common stockholders. At December 31, 1998, the Series
A Preferred Stock fair value approximates book value and accrued dividends
payable relating to this stock totaled $1,565,000.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The Apollo Investors have also granted the Company an option to sell the
Apollo Investors an additional 650,000 shares of its 9.2% Series B Junior
Cumulative Convertible Preferred Stock, par value $.001 per share (the 'Series B
Preferred Stock'), for an aggregate purchase price of $65 million. The Company
may exercise its option to require the Apollo Investors to purchase the Series B
Preferred Stock at any time prior to September 23, 1999. The terms of the Series
B Preferred Stock are similar to those of the Series A Preferred Stock. The
Company recorded the value of the Series B Preferred Stock option at fair value
and recorded approximately $180,000 of deemed dividends related primarily to the
amortization of the value of the option.

   WARRANTS

     In connection with the Company's initial public offering in 1994, the
Company issued warrants to purchase 745,970 shares of Common Stock.
Additionally, the Company issued to the underwriters as consideration warrants
to purchase 123,560 shares of the Company's Common Stock. In September 1996, the
Company received proceeds of $4,589,000 relating to the exercise of 864,848
warrants and the remaining 4,682 warrants expired unexercised. Of the warrants
exercised, 764,848 shares of Common Stock were issued in exchange for cash at a
purchase price of $6.00 per share and 27,083 shares of Common Stock were issued
in a cashless exercise of 100,000 warrants held by the underwriters.

     In connection with the November 1997 issuance of the 10 1/2% Preferred
Stock, the Company granted to its investment advisor and certain related
persons, in lieu of a warrant to purchase shares of 5% Preferred Stock, warrants
to purchase an aggregate of 177,178 shares of 10 1/2% Preferred Stock at an
initial exercise price of $68.47 per share. The exercise price of the warrants
declines by approximately $0.12 per month to $60.24 per share on and after
April 1, 2002. This warrant is convertible at a discount to the then fair market
value of the Common Stock and accordingly, the Company will record, over the
life of the warrant, $1.6 million as a deemed dividend in connection with the
issuance of warrants on preferred stock. During 1998, the Company accreted
dividends of $428,000 related to this warrant. In addition, the Company granted
to an investor warrants to purchase 1,800,000 shares of common stock at $50 per
share during the period from June 15, 1998 until June 15, 2005, subject to
certain conditions. After June 15, 2000, the Company may redeem all of these
warrants, provided that the price of its Common Stock is at least $75 per share
during a specified period. During 1998, the Company accreted dividends of
$6,073,000 related to these warrants.

</TABLE>

     Realization of deferred tax assets at the balance sheet date is dependent
upon future earnings, which are uncertain. Accordingly, a full valuation
allowance was recorded against the assets.

     At December 31, 1998, the Company has net operating loss carryforwards of
approximately $15 million for federal and state income tax purposes available to
offset future taxable income. The net operating loss carryforwards expire at
various dates beginning 2008. There may be limitations on the annual utilization
of these net operating losses as a result of certain changes in ownership that
have occurred since the Company's inception. In addition, a significant portion
of costs incurred have been capitalized for tax purposes as a result of the
Company's status as a start-up enterprise. Total start-up costs as of
December 31, 1998 are $32 million. Once the Company begins its active trade or
business, these capitalized costs will be amortized over 60 months. The total
deferred tax asset related to capitalized start-up costs of $13 million includes
$169,000 which, when realized, would not affect financial statement income but
will be recorded directly to stockholders' equity.

12. COMMITMENTS AND CONTINGENCIES

SATELLITE CONSTRUCTION AND LAUNCH SERVICES

     To build and launch the satellites necessary for the operations of CD
Radio, on July 28, 1998, the Company entered into the Loral Satellite Contract
with SS/L. The Loral Satellite Contract provides for SS/L to construct, launch
and deliver three satellites in-orbit and checked-out, to construct for the
Company a fourth satellite for use as a ground spare and to become the Company's
launch services provider. The Company is committed to make aggregate payments of
approximately $718 million under the Loral Satellite Contract. Approximately
half of these payments are contingent upon SS/L meeting specified milestones in
the construction of the satellites. SS/L has agreed to defer $50 million total
of payments due in 1999 and 2000 until 2002 and 2003. As of December 31, 1998,
$221 million of this commitment has been satisfied. Future payments are due as
follows: $218 million in 1999, $229 million in 2000, $25 million in 2002 and $25
million in 2003.

     In the event of a satellite or launch failure, the Company will be required
to pay Loral the full-deferred amount for the affected satellite no later than
120 days after the date of the failure. If the Company should elect to put one
of the first three satellites into ground storage, rather than having it shipped
to the launch site, the full-deferred amount for the affected satellite will
become due within 60 days of such election.

INTEGRATED CIRCUITS

     During 1998, the Company signed an agreement with Lucent Technologies, Inc.
('Lucent') pursuant to which Lucent has agreed to use commercially reasonable
efforts to deliver commercial quantities of integrated circuits ('chip sets'),
which will be used in consumer electronic devices capable of receiving the
Company's broadcasts, by December 1999. The Company agreed to pay Lucent the
costs of the chip set development work totaling $9 million. On February 1, 1999,
the Company and Lucent amended and restated this agreement due to the design and
development of the chip sets requiring more engineering resources than
originally estimated. Lucent will now use commercially reasonable efforts to
deliver commercial quantities of chip sets by June 2000. The estimates of the
development work in this amended contract total $27 million.
