1.  Business

          Sirius Satellite Radio Inc. broadcasts digital-quality audio from
three orbiting satellites throughout the continental United States for a monthly
subscription fee of $12.95. We deliver 60 streams of 100% commercial-free music
in virtually every genre, and over 40 streams of news, sports, weather, talk,
comedy, public radio and children's programming.

          Since inception, we have used substantial resources to develop our
satellite radio system. Our satellite radio system consists of our FCC license,
satellite system, national broadcast studio, terrestrial repeater network and
satellite telemetry, tracking and control facilities.

          As of June 30, 2003, we had 105,186 subscribers. We consider
subscribers to be those who have agreed to pay for our service and have
activated their SIRIUS radio, including those who are currently in promotional
periods, and active SIRIUS radios under our agreement with Hertz Corporation.
Our primary source of revenue is subscription and activation fees. In addition,
we derive revenues from selling limited advertising on our non-music streams.

2.   Recent Financings; Recapitalization

at the option of the holder, into shares of our common stock at any time at a
conversion rate of 724.6377 shares of common stock for each $1,000.00 principal

               of our 14 1/2% Senior Secured Notes due 2009, and $14,717 in

due 2007, 14 1/2% Senior Secured Notes due 2009 and 8 3/4% Convertible
Subordinated Notes due 2009 were issued to eliminate substantially all of the
restrictive covenants. Holders of our debt also waived any existing events of
default or events of default caused by the restructuring.

3.   Summary of Significant Accounting Policies

     Basis of Presentation

          The accompanying unaudited consolidated financial statements,
including the accounts of Sirius Satellite Radio Inc. and our wholly owned
subsidiary, have been prepared in accordance with accounting principles
generally accepted in the United States and the instructions to Form 10-Q and
Article 10 of Regulation S-X for interim financial reporting. In the opinion of
management, all adjustments (consisting only of normal, recurring adjustments)
considered necessary for a fair presentation have been included. All
intercompany transactions have been eliminated in consolidation. Our
consolidated financial statements should be read together with our consolidated
financial statements and the notes thereto contained in our Annual Report on
Form 10-K for the year ended December 31, 2002.

     Revenue Recognition

          Revenue from subscribers consists of subscription fees, including
revenue derived from our agreement with Hertz, and non-refundable activation
fees. We recognize subscription fees as our service is provided. Activation fees
are recognized ratably over the estimated term of a subscriber relationship,
currently 3.5 years. The estimated term of a subscriber relationship is based on
market research and management's judgment and, if necessary, will be refined in
the future as historical data becomes available. We record an estimate of
mail-in rebates that are paid by us directly to subscribers as a reduction to
subscription revenue in the period the subscriber activates our service.

          We recognize revenues from the sale of limited advertising on our
non-music streams as the advertising is broadcast. Agency fees are calculated
based on a stated percentage applied to gross billing revenue for our
advertising inventory and are reported as a reduction of advertising revenue.

     Stock Options

          We have adopted the disclosure provisions of Statement of Financial
Accounting Standards ("SFAS") No. 148, "Accounting for Stock-Based
Compensation--Transition and Disclosure--An Amendment of FASB Statement No.
123." In addition, we have elected to continue using the intrinsic value method
to measure the compensation costs of stock-based awards granted to employees in
accordance with Accounting Principles Board ("APB") Opinion No. 25, "Accounting
for Stock Issued to Employees"; as a result, we recognize compensation expense
for employee stock options granted at a price less than the market value of our
common stock on the date of grant.

          The following table illustrates the effect on net loss applicable to
common stockholders and net loss per share applicable to common stockholders
had stock-based employee compensation been recorded based on the fair value
method under SFAS No. 123, "Accounting for Stock-Based Compensation."

          Option valuation models require highly subjective assumptions,
including the expected stock price volatility, which may be significantly
different from those of traded options. Because changes in subjective
assumptions can materially affect the fair value estimate, it is our opinion
that the existing models do not necessarily provide a reliable single measure of
the fair value of our stock-based awards. The Black-Scholes option valuation
model was developed for use in estimating the fair value of traded options,
which have no vesting restrictions and are fully transferable. The pro forma
stock-based employee compensation was estimated using the Black-Scholes option
pricing model with the following assumptions for each period:

          In accordance with APB Opinion No. 25, we use the intrinsic value
method to measure the compensation costs of stock-based awards granted to
employees as the excess of the market value of our common stock on the date of
grant over the exercise price. We record these compensation costs over the
vesting period of the stock-based award.

          We account for stock-based awards granted to non-employees at fair
value in accordance with SFAS No. 123.

          In accordance with Financial Accounting Standards Board ("FASB")
Interpretation No. 44, "Accounting for Certain Transactions Involving Stock
Compensation," we record compensation charges or benefits related to repriced
stock options based on the market value of our common stock until the repriced
stock options are exercised, forfeited or expire.

     Debt Restructuring

          We recorded a gain of $256,538 in connection with the restructuring of
our long-term debt in March 2003. This gain represents the difference between
the carrying value of our 15% Senior Secured Discount Notes due 2007, 14 1/2%
Senior Secured Notes due 2009, Lehman term loans and Loral term loans, including
accrued interest, and the fair market value of the common stock issued, adjusted
for unamortized debt issuance costs and direct costs associated with the
restructuring. This gain is net of a loss on our 8 3/4% Convertible Subordinated
Notes due 2009 exchanged in the restructuring. This loss represents the
difference between the fair market value of the common stock issued in the
exchange and the fair market value of the common stock which would have been
issued under the original conversion ratio, including accrued interest, adjusted
for unamortized debt issuance costs and direct costs associated with the
restructuring.

     Preferred Stock Deemed Dividend

          We recorded a deemed dividend of $79,510 in connection with the
exchange in March 2003 of all outstanding shares of our preferred stock for
shares of our common stock and warrants. This deemed dividend represents the
difference between the fair market value of the common stock and warrants issued
in exchange for all outstanding shares of our 9.2% Series A Junior Cumulative
Convertible Preferred Stock, 9.2% Series B Junior Cumulative Convertible
Preferred Stock and 9.2% Series D Junior Cumulative Convertible Preferred Stock
and the fair market value of the common stock which would have been issued under
the original conversion ratios, adjusted for unamortized issuance costs and
direct costs associated with the exchange of the preferred stock.

     Net Loss Per Share

          Basic net loss per share is based on the weighted average common
shares outstanding during each reporting period. Diluted net loss per share
adjusts the weighted average for the potential dilution that could occur if
common stock equivalents (convertible preferred stock, convertible debt,
warrants and stock options) were exercised or converted into common stock.
Approximately 164,807,000 and 16,152,000 common stock equivalents were
outstanding as of June 30, 2003 and 2002, respectively, and were excluded from
the calculation of diluted net loss per share, as they were anti-dilutive.

     Marketable Securities

          Marketable securities consist of U.S. government notes and U.S.
government agency obligations. Effective April 1, 2002, we began classifying
marketable securities as available-for-sale securities rather than trading
securities because we no longer intend to actively buy and sell marketable
securities with the objective of generating trading profits. Available-for-sale
securities are carried at fair market value and unrealized gains and losses are
included as a component of stockholders' equity. Prior to April 1, 2002,
marketable securities were classified as trading securities and unrealized
holding gains and losses were recognized in earnings. Marketable securities held
at June 30, 2003 and December 31, 2002 mature within one year from the date of
purchase. We had an unrealized holding loss on marketable securities of $41 as
of June 30, 2003 and an unrealized holding gain of $913 as of December 31,
2002.

     Classification of Long-Term Debt and Accrued Interest

          In accordance with SFAS No. 6, "Classification of Short-Term
Obligations Expected to be Refinanced," the current portion of long-term debt
and accrued interest that were exchanged for shares of our common stock in March
2003 were classified as long-term liabilities as of December 31, 2002.

     Asset Retirement Obligation

          In accordance with SFAS No. 143, "Accounting for Asset Retirement
Obligations," we recorded costs equal to the present value of the future
obligation associated with the retirement of our terrestrial repeater equipment.
These costs include an amount which we estimate will be sufficient to satisfy
our obligations under leases to remove our terrestrial repeater equipment and
restore the sites to their original condition and are included in long-term
liabilities. The following table reconciles the beginning and ending aggregate
carrying amount of this asset retirement obligation.

     Use of Estimates

          The preparation of consolidated financial statements in conformity
with accounting principles generally accepted in the United States requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities at the date of the consolidated financial statements and
the reported amounts of expenses during the reported period. Estimates involve
judgments with respect to, among other things, various future factors which are
difficult to predict and are beyond our control. Actual amounts could differ
from these estimates.

     Reclassifications

          Certain amounts in the prior years consolidated financial statements
have been reclassified to conform to the current presentation.

     Recent Accounting Pronouncements

          In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain
Financial Instruments with Characteristics of both Liabilities and Equity,"
which is effective for all financial instruments created or modified after May
31, 2003 and otherwise effective at the beginning of the first interim period
beginning after June 15, 2003. SFAS No. 150 establishes standards for
classifying and measuring as liabilities certain financial instruments that
embody obligations of the issuer and have characteristics of both liabilities
and equity. We do not believe that our adoption of SFAS No. 150 will have a
material impact on our financial position or results of operations.

4. Subscriber Revenue

          Subscriber revenue, which consists of subscription and non-refundable
activation fees, was partially offset by the cost of mail-in rebate programs. An
estimate of mail-in rebates that are paid by us directly to subscribers are
recorded as a reduction to subscriber revenue in the period the subscriber
activates our service. Subscriber revenue consists of the following:



                                                   For the Three Months   For the Six Months

5. Non-cash Stock Compensation

          We record non-cash stock compensation benefits or expenses in
connection with the grant of certain stock options, the issuance of common stock
to employees and the issuance of common stock to our employee benefit plans. We
recognized a non-cash stock compensation benefit of $123 and non-cash stock
compensation expense of $436 for the three and six months ended June 30, 2003,
respectively. We recognized non-cash stock compensation expense of $491 and a
non-cash stock compensation benefit of $8,533 for the three and six months ended
June 30, 2002, respectively.

          The non-cash stock compensation expense and benefit for the three and
six months ended June 30, 2003 includes a $314 benefit related to certain
performance conditions of restricted stock issued to an employee that we
anticipate will not be satisfied. The non-cash stock compensation benefit for
the six months ended June 30, 2002 includes a non-cash stock compensation
benefit of $9,717 related to options that were repriced in April 2001.

6. Supplemental Cash Flow Information

          We paid $6,854 and $21,310 for interest during the six months ended
June 30, 2003 and 2002, respectively. We have incurred the following non-cash
operating, investing and financing activities:

7. Property and Equipment

     Subscriber Management System

          On April 17, 2003, we terminated our agreement with Sentraliant, the
company that developed and operated our previous subscriber management system.
Pursuant to that agreement, we paid Sentraliant $5,000 to terminate our
agreement, of which approximately $1,000 related to operation fees. As a result
of this termination, we recorded a non-cash charge of $14,465 related to the net
book value of our subscriber management system. These costs are included in
customer service and billing in the accompanying consolidated statements of
operations for the three and six months ended June 30, 2003.

8. Long-term Debt

     Our long-term debt consists of the following:

and restated certificate of incorporation with the Secretary of State of the
State of Delaware on March 4, 2003.

     Preferred Stock

                   SIRIUS SATELLITE RADIO INC. AND SUBSIDIARY
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)
             (Dollar amounts in thousands, unless otherwise stated)
                                   (Unaudited)

Satellite and Transmission

          We have entered into an agreement with a provider of satellite
services to operate our off-site satellite telemetry, tracking and control
facilities.

Programming and Content

          We have entered into agreements with licensors of music and non-music
programming and, in certain instances, are obligated to pay license fees,
guarantee minimum advertising revenue share or purchase advertising on
properties owned or controlled by these licensors. In addition, we have
agreements with various rights organizations pursuant to which we pay royalties
for public performances of music.

Customer Service and Billing

          We have entered into agreements with third parties to provide customer
service, billing service and subscriber management.

Sales and Marketing

          We have entered into various marketing and sponsorship agreements to
promote our brand and are obligated to make payments to sponsors, retailers,
automakers and radio manufacturers.

Chip Set Development and Production

          We have entered into an agreement with Agere Systems, Inc. ("Agere")
to develop and produce chip sets for use in SIRIUS radios. This agreement
requires Agere to produce a minimum quantity of chip sets during each year of
the agreement.

Other Commitments

          We have agreed to use reasonable efforts to assist certain
manufacturers of SIRIUS radios and components for those radios in the event that
production of such radios and components are greater than sales. In certain
circumstances, these reasonable efforts may include the purchase of unsold
SIRIUS radios or components by us. In addition, we have also entered into
agreements with automakers, radio manufacturers and others that include
per-radio and per-subscriber required payments and revenue sharing arrangements.
These future costs are dependent upon many factors and are difficult to
anticipate; however, these costs may be substantial. We may enter into
additional programming, marketing and other agreements that contain provisions
similar to our current agreements.

11. Subsequent Events

          Our board of directors recently approved and issued stock options and
restricted stock which represent the right to acquire up to 64.9 million shares
of our common stock under the Sirius Satellite Radio 2003 Long-Term Stock
Incentive Plan. Based on the market value of our common stock of $1.62, the
closing bid price of our common stock on August 8, 2003, these awards would
result in an aggregate non-cash stock compensation charge of approximately $61.0
million over the period commencing on the date of grant and ending in July 2008.
The exact amount and timing of this charge is contingent upon a number of
factors, including the price of our common stock and the vesting date of these
stock options and restricted stock, and could materially change.

Management's Discussion and Analysis of Financial Condition and Results of
Operations

         (All dollar amounts are in thousands, unless otherwise stated)

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
forward-looking statements made in this Quarterly Report on Form 10-Q and in
other reports and documents published by us from time to time. Any statements
about our beliefs, plans, objectives, expectations, assumptions, 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." Any
forward-looking statements are qualified in their entirety by reference to the
factors discussed throughout our Annual Report on Form 10-K for the year ended
December 31, 2002 (the "Form 10-K") and in other reports and documents published
by us from time to time, particularly the risk factors described under "Business
-- Risk Factors" in Part I of the Form 10-K. Among the significant factors that
could cause our actual results to differ materially from those expressed in the
forward-looking statements are:

          o    our competitive position; XM Satellite Radio, the other satellite
               radio service provider in the United States, began offering its
               service before us, has substantially more subscribers than us and
               may have certain competitive advantages;

          o    our dependence upon third parties to manufacture, distribute,
               market and sell SIRIUS radios and components for those radios;

          o    the unproven market for our service; and

          o    the useful life of our satellites, which have experienced circuit
               failures on their solar arrays and may not be covered by
               insurance.

          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. In addition, 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, to
reflect the occurrence of unanticipated events or otherwise. New factors emerge
from time to time, and it is not possible for us to predict which will arise or
to 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.

Overview

          We broadcast digital-quality audio from three orbiting satellites
throughout the continental United States for a monthly subscription fee of
$12.95. We deliver 60 streams of 100% commercial-free music in virtually every
genre, and over 40 streams of news, sports, weather, talk, comedy, public radio
and children's programming. We hold one of only two licenses issued by the FCC
to operate a national satellite radio system.


          As of June 30, 2003, we had 105,186 subscribers. We consider
subscribers to be those who have agreed to pay for our service and have
activated their SIRIUS radio, including those who are currently in promotional
periods, and active SIRIUS radios under our agreement with Hertz. We derive
revenue from:

          o    subscription fees, including revenue derived from our agreement
               with Hertz,

          o    activation fees collected from our subscribers, and

          o    selling limited advertising on our non-music streams.

Results of Operations

Three Months Ended June 30, 2003 Compared with Three Months Ended June 30, 2002

          Total Revenue. Total revenue increased to $2,073 from $70 for the
three months ended June 30, 2003 and 2002, respectively. Total revenue for the
three months ended June 30, 2003 included subscriber revenue of $2,029,
consisting of subscription and non-refundable activations fees, net advertising
revenue of $27 and revenue from other sources of $17. Total revenue for the
three months ended June 30, 2002 included subscription revenue of $50 and
advertising revenue of $20.

          Subscriber Revenue. The increase in subscriber revenue of $1,979 was
attributable to the growth of subscribers to our service. We added 37,127 net
new subscribers during the three months ended June 30, 2003. Subscriber revenue
for the three months ended June 30, 2003 included subscription revenue of
$2,719 and activation revenue of $63, which was partially offset by $753 of
costs associated with mail-in rebate programs. Subscriber revenue for the three
months ended June 30, 2002 included subscription revenue of $48 and activation
revenue of $2. Activation fees are recognized ratably over the term of the
subscriber relationship, currently estimated to be 3.5 years. An estimate of
mail-in rebates that are paid by us directly to subscribers are recorded as a
reduction to subscription revenue in the period the subscriber activated our
service. Future subscription revenue will be dependent upon, among other things,
growth of our subscriber base, discounts and mail-in rebates offered to
subscribers and the identification of additional revenue streams from
subscribers.

               Average monthly revenue per subscriber ("ARPU"). ARPU for the
          three months ended June 30, 2003 was $7.91. Excluding the cost of
          mail-in rebate programs, ARPU for the three months ended June 30, 2003
          was $10.84. ARPU, which is not a measure of financial performance
          under accounting principles generally accepted in the United States,
          is derived from total subscriber revenue over the daily weighted
          average number of subscribers for the period. Future ARPU will be
          dependent upon the amount and timing of subscriber discounts, mail-in
          rebate programs, and the identification of additional revenue streams
          from subscribers.

          Advertising Revenue. Advertising revenue, net of agency fees of $5,
was $27 for the three months ended June 30, 2003. Advertising revenue, net of
agency fees of $3, was $20 for the three months ended June 30, 2002. We
recognize advertising revenue from the sale of limited advertising on our
non-music streams as it is broadcast.

          Satellite and Transmission. Satellite and transmission expenses
decreased to $7,688 for the three months ended June 30, 2003 from $8,450 for the
three months ended June 30, 2002. Satellite and transmission expenses consist
primarily of personnel costs, in-orbit satellite insurance expense and costs
associated with the operation and maintenance of our satellite tracking,
telemetry and control system, terrestrial repeater network and national
broadcast studio. The decrease in satellite and transmission expense was
primarily attributable to decreased in-orbit satellite insurance expense as a
result of reduced in-orbit satellite insurance coverage. Our current policies
cover each of our three satellites up to $110,000 in the event of a total or
constructive total loss. We expect that a significant portion of our satellite
and transmission costs will remain relatively constant, and that increases or
decreases in satellite and transmission costs will be due to costs of insuring
our in-orbit satellites and modest additions to our terrestrial repeater
network.

          Programming and Content. Programming and content expenses increased to
$7,639 for the three months ended June 30, 2003 from $4,125 for the three months
ended June 30, 2002. Programming and content expenses include costs to acquire
programming from third parties, on-air talent costs, broadcast royalties and
programming personnel costs. The increase in costs was primarily attributable to
broadcast royalties and on-air talent.

               Acquired programming. We have entered into various agreements
          with third parties for music and non-music programming. These
          agreements require us to share advertising revenue, pay license fees
          and purchase advertising on media properties owned or controlled by
          the licensor. In addition, certain agreements include guaranteed
          obligations which we recognize on a straight-line basis over the term
          of the applicable agreement. Advertising revenue share is expensed as
          the associated revenue is recognized; license fees are expensed as the
          programming is aired and purchased advertising is recorded as a sales
          and marketing expense when the advertising is aired.

               Broadcast royalties. We have entered into agreements with various
          rights organizations pursuant to which we pay royalties for public
          performances of music. These agreements include fixed and variable

                                          15




          payment obligations. We record variable broadcast royalties as they
          are incurred and fixed obligations on a straight-line basis over the
          term of the applicable agreement.

          We anticipate that our programming costs will increase over time as we
continue to develop our streams and share advertising revenue from the sale of
advertising on our non-music streams.

          Customer Service and Billing. Customer service and billing costs
increased to $16,320 for the three months ended June 30, 2003 from $1,882 for
the three months ended June 30, 2002. Customer service and billing costs include
costs associated with the operation of our customer service center and
subscriber management system. The increase in costs during the 2003 quarter was
due to a $14,465 loss on the disposal of our prior subscriber management system
as a result of the termination of our agreement with Sentraliant, the company
that developed and operated that system.

          Sales and Marketing. Sales and marketing expenses increased to $39,516
for the three months ended June 30, 2003 from $30,901 for the three months ended
June 30, 2002. Sales and marketing expenses include costs related to sales and
marketing personnel, advertising media and production activities, sponsorships,
costs to acquire subscribers and payments to reimburse retailers, distributors
and automakers for marketing and promotional activities. Sales and marketing
expenses increased as a result of our national advertising campaign, increased
marketing activities by automakers and increased sponsorship activities.

               Advertising Media and Production. These costs include promotional
          events, media, advertising production and market research. Media is
          expensed when it is aired and advertising production costs are
          expensed as incurred.

               Retail and Distribution. These costs include advertising,
          residuals and market development funds. Advertising is expensed as
          incurred. Residuals are monthly fees paid based upon the number of
          subscribers using a SIRIUS radio purchased from a retailer and are
          expensed as incurred. Market development funds are fixed and variable
          payments to reimburse retailers for the cost of advertising and other
          product awareness activities. Fixed market development funds are
          expensed over the periods specified in the applicable agreement;
          variable costs are expensed at the time a subscriber is activated.

               Automakers. We have entered into agreements with DaimlerChrysler,
          Ford, BMW and other automakers which anticipate that such automakers
          will manufacture, market and sell vehicles which are equipped with
          SIRIUS radios ("Enabled Vehicles"). Under many of these agreements,
          we share a portion of the revenue we derive from subscribers using
          Enabled Vehicles. This revenue share is expensed as the corresponding
          subscription revenue is earned. We also reimburse automakers for
          certain advertising, promotional, hardware and engineering costs. We
          record expenses associated with these reimbursements as incurred or on
          a straight-line basis over the contract period for guaranteed
          obligations.

               We have issued a warrant to purchase 4,000,000 shares of our
          common stock to each of DaimlerChrysler and Ford. These warrants
          become exercisable based on, among other conditions, the number of
          Enabled Vehicles the automakers manufacture. We record warrant expense
          for interim reporting periods based upon the performance of the
          automakers in manufacturing Enabled Vehicles and the fair value of the
          warrants at each reporting date. The final measurement date of these
          warrants will be the date that each performance commitment for such
          warrants is satisfied.

               Subscriber Acquisition Costs. Subscriber acquisition costs
          increased to $9,275 for the three months ended June 30, 2003 from
          $8,626 for the three months ended June 30, 2002. Subscriber
          acquisition costs per gross activation decreased to $229 for the three
          months ended June 30, 2003, as compared to $299 for the three months
          ended March 31, 2003. Subscriber acquisition costs include incentives
          for the purchase, installation and activation of SIRIUS radios, as
          well as subsidies paid to radio manufacturers, automakers, retailers
          and payments to Agere. Certain subscriber acquisition costs are
          recorded in advance of acquiring a subscriber. Subscriber acquisition
          costs do not include advertising and promotional activities, loyalty
          payments to distributors and dealers of SIRIUS radios, revenue sharing
          payments to manufacturers of SIRIUS radios and guaranteed payments to
          automakers. We retain ownership of the SIRIUS radios used in our
          agreement with Hertz; as a result, amounts capitalized in connection
          with this program are not included in our subscriber acquisition
          costs.

          We expect sales and marketing expenses to increase in the future as we
continue to build brand awareness through national advertising and continue to
offer subsidies, commissions and other incentives to acquire

                                        16




subscribers. In addition, we expect to incur significant costs related to our
agreements with automakers as they increase production of Enabled Vehicles. We
anticipate that the costs of certain subsidized components of SIRIUS radios will
decrease as manufacturers experience economies of scale in production and we
secure additional manufacturers of these components.

          General and Administrative. General and administrative expenses
increased to $12,464 for the three months ended June 30, 2003 from $8,588 for
the three months ended June 30, 2002. General and administrative expenses
include rent and occupancy, accounting, legal and public relations costs and
costs of general and administrative personnel. The increase was a result of
approximately $4,000 of costs to terminate our agreement with Sentraliant,
the company that developed and operated our prior subscriber management system.

          Research and Development. Research and development costs decreased to
$4,904 for the three months ended June 30, 2003 from $13,425 for the three
months ended June 30, 2002. Research and development costs include costs to
develop our next generation chip sets, new product designs and personnel costs.
The decrease related to a payment of $8,134 to Panasonic during the second
quarter of 2002, which released us from a purchase commitment and reduced the
factory price of SIRIUS radios.

               Chip Set Development. We have an agreement with Agere to develop
          and produce chip sets for use in SIRIUS radios. This agreement
          requires Agere to manufacture a minimum quantity of chip sets during
          each year of the agreement. The agreement requires us to pay Agere
          fixed monthly payments. These costs are allocated between research
          and development and sales and marketing for development work and
          chip set production, respectively.

          The amount of our future research and development costs is dependent
upon modifications to our existing technology and enhancements to SIRIUS radios.

          Depreciation Expense. Depreciation expense increased to $23,463 for
the three months ended June 30, 2003 from $22,099 for the three months ended
June 30, 2002. We expect depreciation expense to remain relatively constant as
our satellite radio system is complete.

          Non-cash Stock Compensation. We recognized a non-cash stock
compensation benefit of $123 and non-cash stock compensation expense of $491 for
the three months ended June 30, 2003 and 2002, respectively. Non-cash stock
compensation includes charges and benefits associated with the grant of certain
stock options and the issuance of our common stock to employees and an employee
benefit plan. The non-cash stock compensation benefit for the three months ended
June 30, 2003 was principally a result a $314 benefit related to certain
performance conditions of restricted stock that we anticipate will not be
satisfied.

          Interest and Investment Income. Interest and investment income
decreased to $1,327 for the three months ended June 30, 2003 from 1,517 for the
three months ended June 30, 2002. This decrease was attributable to lower
returns on our investments in U.S. government securities during the 2003 period.

          Interest Expense. Interest expense decreased to $3,365 for the three
months ended June 30, 2003 from $24,893 for the three months ended June 30,
2002, net of amounts capitalized of $0 and $1,025, respectively. The decrease
in interest expense was a result of the exchange of approximately $636,000 in
aggregate principal amount at maturity of our outstanding long-term debt for
common stock in March 2003.

Six Months Ended June 30, 2003 Compared with Six Months Ended June 30, 2002

          Total Revenue. Total revenue increased to $3,664 from $103 for the six
months ended June 30, 2003 and 2002, respectively. Total revenue for the six
months ended June 30, 2003 included subscriber revenue of $3,583, consisting of
subscription and non-refundable activations fees, net advertising revenue of $44
and revenue from other sources of $37. Total revenue for the six months ended
June 30, 2002 included subscription revenue of $54 and advertising revenue of
$49.

          Subscriber Revenue. The increase in subscriber revenue of $3,529 was
attributable to the growth of subscribers to our service. We added 75,239 net
new subscribers during the six months ended June 30, 2003. Subscriber revenue
for the six months ended June 30, 2003 included subscription revenue of $4,242
and activation revenue of $106, which was partially offset by $765 of costs
associated with mail-in rebate programs. Subscriber revenue, for the six months
ended June 30, 2002, included subscription revenue of $52 and activation revenue
of $2.

                                      17




               Average monthly revenue per subscriber. ARPU for the six months
          ended June 30, 2003 was $8.94. Excluding the cost of mail-in rebate
          programs, ARPU for the six months ended June 30, 2003 was $10.85.

          Advertising Revenue. Advertising revenue, net of agency fees of $8,
was $44 for the six months ended June 30, 2003. Advertising revenue, net of
agency fees of $9, was $49 for the six months ended June 30, 2002.

          Satellite and Transmission. Satellite and transmission expenses
decreased to $15,555 for the six months ended June 30, 2003 from $17,207 for the
six months ended June 30, 2002. The decrease in satellite and transmission
expense was primarily attributable to decreased in-orbit satellite insurance
expense as a result of reduced in-orbit satellite insurance coverage.

          Programming and Content. Programming and content expenses increased to
$14,213 for the six months ended June 30, 2003 from $7,908 for the six months
ended June 30, 2002. The increase in costs was primarily attributable to
broadcast royalties and on-air talent.

          Customer Service and Billing. Customer service and billing costs
increased to $18,522 for the six months ended June 30, 2003 from $3,724 for the
six months ended June 30, 2002. The increase in costs during the quarter was due
to a $14,465 loss on the disposal of our prior subscriber management system as a
result of the termination of our agreement with Sentraliant.

          Sales and Marketing. Sales and marketing expenses increased to $84,856
for the six months ended June 30, 2003 from $46,560 for the six months ended
June 30, 2002. Sales and marketing expenses increased due to the launch of our
national advertising campaign, certain marketing activities by retailers,
automakers and radio manufacturers, sponsorship activities and the costs
associated with subsidies paid to radio and chip set manufacturers.

               Subscriber Acquisition Costs. Subscriber acquisition costs
          increased to $21,138 for the six months ended June 30, 2003 from
          $10,291 for the six months ended June 30, 2002. Subscriber acquisition
          costs per gross activation was $263 for the six months ended June 30,
          2003.

          General and Administrative. General and administrative expenses
increased to $21,558 for the six months ended June 30, 2003 from $16,128 for the
six months ended June 30, 2002. The increase was primarily a result of
approximately $4,000 of costs to terminate our agreement with Sentraliant.

          Research and Development. Research and development costs decreased to
$9,887 for the six months ended June 30, 2003 from $21,138 for the six months
ended June 30, 2002. The decrease related to a payment of $8,134 to Panasonic in
the second quarter of 2002, which released us from a purchase commitment and
reduced the factory price of SIRIUS radios.

          Depreciation Expense. Depreciation expense increased to $47,563 for
the six months ended June 30, 2003 from $36,580 for the six months ended June
30, 2002. The increase was due to a full period of depreciation of our satellite
radio system, which began in February 2002.

          Non-cash Stock Compensation. We recognized non-cash stock compensation
expense of $436 and a non-cash stock compensation benefit of $8,533 for the six
months ended June 30, 2003 and 2002, respectively. The non-cash stock
compensation expense of $436 for the six months ended June 30, 2003 includes a
$314 benefit related to certain performance conditions of restricted stock that
we anticipate will not be satisfied. The non-cash stock compensation benefit for
the six months ended June 30, 2002 was principally a result of a $9,717 benefit
related to the repricing of certain employee stock options in April 2001.

          Debt Restructuring. We recorded a gain of $256,538 in connection with
the restructuring of our long-term debt. This gain represents the difference
between the carrying value of our 15% Senior Secured Discount Notes due 2007, 14
1/2% Senior Secured Notes due 2009, Lehman term loans and Loral term loans,
including accrued interest, and the fair market value of the common stock
issued, adjusted for unamortized debt issuance costs and direct costs associated
with the restructuring. This gain is net of a loss on our 8 3/4% Convertible
Subordinated Notes due 2009 exchanged in the restructuring. This loss represents
the difference between the fair market value of the common stock issued in the
exchange and the fair market value of the common stock which would have been
issued under the original conversion ratio, including accrued interest, adjusted
for unamortized debt issuance costs and direct costs associated with the
restructuring.

                                       18




          Interest and Investment Income. Interest and investment income
decreased to $2,670 for the six months ended June 30, 2003 from $3,517 for the
six months ended June 30, 2002. This decrease was attributable to lower returns
on our investments in U.S. government securities during the 2003 period.

          Interest Expense. Interest expense decreased to $22,030 for the six
months ended June 30, 2003 from $55,086 for the six months ended June 30, 2002,
net of amounts capitalized of $0 and $5,426, respectively. Interest expense for
the six months ended June 30, 2002 included non-cash costs of $9,650 associated
with the induced conversion of $29,475 in aggregate principal amount of our 8
3/4% Convertible Subordinated Notes due 2009. The decrease in interest expense
is a result of the exchange of approximately $636,000 in aggregate principal
amount at maturity of our outstanding long-term debt for common stock in March
2003.

Cash Flows

Six Months Ended June 30, 2003 Compared With Six Months Ended June 30, 2002

          Net cash used in operating activities decreased to $135,756 from
$194,244 for the six months ended June 30, 2003 and 2002, respectively. The
decrease in cash used in operations was primarily attributable to the change in
the classification of our marketable securities in the second quarter of 2002 to
available-for-sale securities from trading securities. Transactions relating to
trading securities are considered operating activities; transactions relating to
available-for-sale securities are considered investing activities. Excluding our
transactions in marketable securities, cash used in operating activities
increased to $134,571 for the six months ended June 30, 2003 from $118,754 for
the six months ended June 30, 2002. This increase was primarily due to the cost
of our national advertising campaign, the costs of acquiring subscribers and the
cost of producing our music and non-music streams.

          Net cash provided by investing activities for the six months ended
June 30, 2003 increased to $139,821 from $66,975 for the six months ended June
30, 2002. The change from the prior period was principally due to a change in
the classification of our marketable securities from trading securities to
available-for-sale securities during the second quarter of 2002. Excluding our
transactions in marketable securities, cash used in investing activities
decreased to $10,179 from $33,150 for the six months ended June 30, 2003 and
2002, respectively. This decrease was a result of a reduction in capital
expenditures as we completed the construction of our satellite radio system
during 2002.

          Net cash provided by financing activities was $532,095 and $147,508
for the six months ended June 30, 2003 and 2002, respectively. During 2003, we
sold 211,730,379 and 86,250,000 shares of common stock resulting in net proceeds
of $197,112 and $145,547, respectively. In addition, we issued $201,250 in
principal amount of our 3 1/2% Convertible Notes due 2008 resulting in net
proceeds of $194,224, and incurred costs associated with our debt restructuring
of $4,737. During the six months ended June 30, 2002, we sold 16,000,000 shares
of common stock resulting in net proceeds of $147,500.

Liquidity and Capital Resources

          At June 30, 2003, we had cash, cash equivalents and marketable
securities totaling $560,093 and working capital of $524,050, compared with
cash, cash equivalents and marketable securities totaling $173,702 and working
capital of $151,289 at December 31, 2002.

          We estimate that our cash, cash equivalents and marketable securities
are sufficient to cover our estimated funding needs through cash flow breakeven,
the point at which our revenues are sufficient to fund expected operating
expenses, capital expenditures, working capital requirements, interest and
principal payments and taxes. Our actual funding requirements could vary
materially from our current estimates. We may have to raise more funds to remain
in business and continue to develop and market our satellite radio service.

          Our financial projections are based on assumptions which we believe
are reasonable but contain significant uncertainties, including, most
importantly, the length of time and level of costs necessary to obtain the
number of subscribers required to sustain our operations. At June 30, 2003, we
had 105,186 subscribers. We estimate that we will need approximately two million
subscribers before we achieve cash flow breakeven which we estimate to be in the
second quarter of 2005.

                                     19




Recent Financings; Recapitalization

          In June 2003, we sold 86,250,000 shares of our common stock in an
underwritten public offering resulting in net proceeds of $145,547.

          In May 2003, we issued $201,250 in aggregate principal amount of
our 3 1/2% Convertible Notes due 2008 in an underwritten public offering
resulting in net proceeds of $194,224. Our 3 1/2% Convertible Notes due 2008 are
convertible, at the option of the holder, into shares of our common stock at any
time at a conversion rate of 724.6377 shares of common stock for each $1,000.00
principal amount, or $1.38 per share of common stock, subject to certain
adjustments.

          On March 7, 2003, we completed a series of transactions to restructure
our debt and equity capitalization. As part of these transactions:

          o    we issued 545,012,162 shares of our common stock in exchange for
               approximately 91% of our then outstanding debt, including all of
               our Lehman term loans, all of our Loral term loans, $251,230 in
               aggregate principal amount at maturity of our 15% Senior Secured
               Discount Notes due 2007, $169,742 in aggregate principal amount
               of our 14 1/2% Senior Secured Notes due 2009, and $14,717 in
               aggregate principal amount of our 8 3/4% Convertible Subordinated
               Notes due 2009;

          o    we issued 39,927,796 shares of our common stock and warrants to
               purchase 45,416,690 shares of our common stock in exchange for
               all outstanding shares of our 9.2% Series A and B Junior
               Cumulative Convertible Preferred Stock held by Apollo;

          o    we issued 37,065,069 shares of our common stock and warrants to
               purchase 42,160,424 shares of our common stock in exchange for
               all outstanding shares of our 9.2% Series D Junior Cumulative
               Convertible Preferred Stock held by Blackstone;

          o    we sold 24,060,271 shares of our common stock to Apollo for an
               aggregate of $25,000;

          o    we sold 24,060,271 shares of our common stock to Blackstone for
               an aggregate of $25,000; and

          o    we sold 163,609,837 shares of our common stock to Oppenheimer for
               an aggregate of $150,000.

          During the three months ended March 31, 2003, we recorded a gain of
$256,538 and a deemed dividend of $79,510 as a result of the exchange
transactions. In connection with the exchange offer relating to our debt, we
also amended the indentures under which our 15% Senior Secured Discount Notes
due 2007, 14 1/2% Senior Secured Notes due 2009 and 8 3/4% Convertible
Subordinated Notes due 2009 were issued to eliminate substantially all of the
restrictive covenants. Holders of our debt also waived any existing events of
default or events of default caused by the restructuring.

Long-Term Debt Obligations

          Long-term debt obligations include principal and interest payments.
As of June 30, 2003, we had $262,452 in aggregate principal amount of
outstanding debt, consisting of $29,200 in aggregate principal amount at
maturity of our 15% Senior Secured Discount Notes due 2007, $30,258 in aggregate
principal amount of our 14 1/2% Senior Secured Notes due 2009, $201,250 in
aggregate principal amount of our 3 1/2% Convertible Notes due 2008 and $1,744
in aggregate principal amount of our 8 3/4% Convertible Subordinated Notes due
2009.

Operating Leases

          We have entered into operating leases related to our national
broadcast studio, office space, terrestrial repeater sites and equipment.

Satellite and Transmission

          We have entered into an agreement with a provider of satellite
services to operate our off-site satellite telemetry, tracking and control
facilities.

Programming and Content

          We have entered into agreements with licensors of music and non-music
programming and, in certain instances, are obligated to pay license fees,
guarantee minimum advertising revenue share or to purchase advertising on
properties owned or controlled by these licensors. In addition, we have
agreements with various rights organizations pursuant to which we pay royalties
for public performances of music.

Customer Service and Billing

          We have entered into agreements with third parties to provide customer
service, billing service and subscriber management.

Sales and Marketing

          We have entered into various marketing and sponsorship agreements to
promote our brand and are obligated to make payments to sponsors, retailers,
automakers and radio manufacturers.

Chip Set Development and Production

          We have entered into an agreement with Agere to develop and produce
chip sets for use in SIRIUS radios. This agreement requires Agere to manufacture
a minimum quantity of chip sets during each year of the agreement.

Other Commitments

          We have agreed to use reasonable efforts to assist certain
manufacturers of SIRIUS radios and components for those radios in the event that
production of such radios and components are greater than sales. In certain
circumstances, these reasonable efforts may include the purchase of unsold
SIRIUS radios or components by us. In addition to the contractual commitments
described above, we have also entered into agreements with automakers, radio
manufacturers and others that include per-radio and per-subscriber required
payments and revenue sharing arrangements. These future costs are dependent upon
many factors and are difficult to anticipate; however, these costs may be
substantial. We may enter into additional programming, marketing and other
agreements that contain provisions similar to our current agreements.

Critical Accounting Policies and Estimates

          Our consolidated financial statements are prepared in accordance with
accounting principles generally accepted in the United States, which require
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 revenues and expenses during the periods. A summary of our
significant accounting policies is contained in Note 3 to the consolidated
financial statements contained in this report. We have identified the following
policies, which were

                                      21




discussed with the Audit Committee of our board of directors, as critical to our
business and understanding our results of operations.

          Subscription Revenue Recognition

               Revenue from subscribers consists of subscription fees, including
          revenue derived from our agreement with Hertz, and non-refundable
          activation fees. We recognize subscription fees as our service is
          provided. Activation fees are recognized ratably over the term of the
          subscriber relationship, currently estimated to be 3.5 years. The
          estimated term of a subscriber relationship is based on market
          research and management's judgment and, if necessary, will be refined
          in the future as historical data becomes available. As required by
          Emerging Issues Task Force No. 01-09, "Accounting for Consideration
          Given by a Vendor to a Customer (Including a Reseller of the Vendor's
          Products)," an estimate of mail-in rebates that are paid by us
          directly to subscribers are recorded as a reduction to subscription
          revenue in the period the subscriber activates our service.

          Subscriber Acquisition Costs

               Subscriber acquisition costs include incentives for the purchase,
          installation and activation of SIRIUS radios, as well as subsidies
          paid to radio manufacturers, retailers and Agere. Certain subscriber
          acquisition costs are recorded in advance of acquiring a subscriber.
          Subscriber acquisition costs do not include advertising and
          promotional activities, loyalty payments to distributors and dealers
          of SIRIUS radios, revenue sharing payments to manufacturers of SIRIUS
          radios and guaranteed payments to automakers. We retain ownership of
          the SIRIUS radios used in our agreement with Hertz; as a result,
          amounts capitalized in connection with this program are not included
          in our subscriber acquisition costs.

          Marketable Securities

               Marketable securities consist of U.S. government agency
          obligations. Effective April 1, 2002, marketable securities were
          classified as available-for-sale securities because management no
          longer intends to buy and sell marketable securities with the
          objective of generating profits. Available-for-sale securities are
          carried at fair market value and unrealized gains and losses are
          included as a component of stockholders' equity. In prior periods,
          marketable securities were classified as trading securities and
          unrealized holding gains and losses were recognized in earnings.

          Long-Lived Assets

               We carry our long-lived assets at cost less accumulated
          depreciation. We review our long-lived assets for impairment whenever
          events or changes in circumstances indicate that the carrying amount
          of an asset is not recoverable. At such time as an impairment in value
          of a long-lived asset is identified, the impairment will be measured
          as the amount by which the carrying amount of a long-lived asset
          exceeds its fair value. To determine fair value we would employ an
          expected present value technique, which utilizes multiple cash flow
          scenarios that reflect the range of possible outcomes and an
          appropriate discount rate.

          Useful Life of Satellite System

               Our satellite system includes the cost of satellite construction,
          launch vehicles, launch insurance, capitalized interest, our spare
          satellite and our terrestrial repeater network. We monitor our
          satellites for impairment whenever events or changes in circumstances
          indicate that the carrying amount of the asset is not recoverable. The
          expected useful lives of our in-orbit satellites are fifteen years
          from the date they were placed into orbit. We are depreciating our
          three in-orbit satellites over their respective remaining useful lives
          beginning February 14, 2002 or, in the case of our spare satellite,
          from the date it was delivered to ground storage on April 19, 2002. If
          placed into orbit, our spare satellite is expected to operate
          effectively for fifteen years.

          FCC License

               We carry our FCC license at cost. Our FCC license has an
          indefinite life and will be evaluated for impairment on an annual
          basis. We completed an impairment analysis of our FCC license on
          November 1,

                                        22




          2002, and determined that there was no impairment. We use projections
          regarding estimated future cash flows and other factors in assessing
          the fair value of our FCC license. If these estimates or projections
          change in the future, we may be required to record an impairment
          charge related to our FCC license.

          Accrued Expenses

               Payments owed to our manufacturing and distribution partners and
          other service providers are expensed during the month in which the
          applicable service is performed. The amount of these expenses are
          dependent upon information provided by our internal systems and
          processes and partner systems and processes. Due to length of time
          necessary to receive accurate information from these partners,
          estimates of amounts due are necessary in order to record monthly
          expenses. In subsequent months expenses are reconciled, and
          adjusted where necessary. Since launching commercial operations, we
          continue to refine the estimation process based on an increased
          understanding of the time requirements, and close working
          relationships with our partners.

Recent Accounting Pronouncements

          In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain
Financial Instruments with Characteristics of both Liabilities and Equity,"
which is effective for all financial instruments created or modified after May
31, 2003 and otherwise effective at the beginning of the first interim period
beginning after June 15, 2003. SFAS No. 150 establishes standards for
classifying and measuring as liabilities certain financial instruments that
embody obligations of the issuer and have characteristics of both liabilities
and equity. We do not believe that our adoption of SFAS No. 150 will have a
material impact on our financial position or results of operations.

Controls and Procedures

          As of June 30, 2003, an evaluation was performed under the supervision
and with the participation of our management, including Joseph P. Clayton, our
President and Chief Executive Officer, and David J. Frear, our Executive Vice
President and Chief Financial Officer, of the effectiveness of the design and
operation of our disclosure and control procedures. Based on that evaluation,
our management, including our chief executive officer and our chief financial
officer, concluded that our disclosure controls and procedures were effective
as of June 30, 2003. There have been no significant changes in our internal
controls or in other factors that could significantly affect these internal
controls subsequent to June 30, 2003.
