1.   Business Activites

         Sirius Satellite Radio Inc., a Delaware corporation, is developing a
service for broadcasting digital quality programming via satellites to vehicles,
homes and portable radios throughout the continental United States. We will
focus exclusively on providing a consumer service; consumer electronics
manufacturers will manufacture the radios required to receive our broadcasts. In
April 1997, we were the winning bidder in an auction by the Federal
Communications Commission for one of two national satellite broadcast licenses
with a winning bid of approximately $83,300. We paid the bid amount during 1997
and were awarded an FCC license on October 10, 1997. Our principal activities to
date have included obtaining regulatory approval for our service, constructing
and launching our three satellite constellation, constructing our national
broadcast studio, acquiring content for our programming, constructing our
terrestrial repeater network, arranging for the development of radios, strategic
planning and market research, recruiting our management team and securing
financing for capital expenditures and working capital.

         The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles and with
the instructions to Form 10-Q and Article 10 of Regulation S-X for interim
financial reporting. Accordingly, our financial statements do not include all
of the information and footnotes required by generally accepted accounting
principles. In the opinion of management, all adjustments (consisting only of
normal, recurring adjustments) considered necessary for fair presentation have
been included. We have not yet recognized any revenues, accordingly, our
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." All intercompany
transactions have been eliminated in consolidation. These financial statements
should be read in connection with our consolidated financial statements and the
notes thereto in our Annual Report on Form 10-K for the year ended December
31, 2000.

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

Marketable Securities and Restricted Investments

         Marketable securities are classified as trading securities and are
stated at market value. Marketable securities consist of obligations of U.S.
government agencies and commercial paper issued by major U.S. corporations with
high credit ratings. We recognized unrealized holding gains on marketable
securities of $2,682 and $968 for the six month periods ended June 30, 2001 and
2000, respectively, and $4,958 for the period May 17, 1990 (date of inception)
to June 30, 2001.

         Restricted investments consist of fixed income securities and are
stated at amortized cost plus accrued interest income. Restricted investments
are classified as held-to-maturity securities and unrealized holding gains and
losses are not reflected in earnings. As of June 30, 2001 and December 31, 2000,
we had an unrealized holding gain of $290 and an unrealized holding loss of $16,
respectively, related to these securities. We are required to hold the
securities included in restricted investments to pay interest on our 14-1/2%
Senior Secured Notes due 2009 through May 15, 2002.

Property and Equipment

         All costs incurred related to activities necessary to prepare our
broadcast system for use are capitalized. To date, such costs consist of
satellite construction and launch, broadcast studio equipment, terrestrial
repeater network construction and capitalized interest.

Net Loss Per Share

         Basic net loss per share is based on the weighted average number of
outstanding shares of our common stock 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. As of June 30, 2001 and 2000, approximately 19,026,000 and
21,347,000 common stock equivalents were outstanding, respectively, and were
excluded from the calculation of diluted net loss per share, as they were
anti-dilutive.

Recent Accounting Pronouncements

         In June 2001, the Financial Accounting Standards Board issued SFAS
No. 141, "Business Combinations" (effective June 30, 2001) and SFAS No. 142,
"Goodwill and Other Intangible Assets" (effective January 1, 2002). SFAS No. 141
prohibits pooling-of-interests accounting for acquisitions. SFAS No. 142
specifies that goodwill and certain intangible assets will no longer be
amortized but instead will be subject to periodic impairment testing. We are in
the process of evaluating the financial statement impact of the adoption of
these statements.

Reclassifications

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

3.   Deferred Satellite Payments

         Under an amended and restated contract (the "Loral Satellite Contract")
with Space Systems/Loral, Inc. ("Loral"), Loral 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 were originally due in quarterly
installments beginning in June 2002. However, the agreement governing these
deferred amounts provides that this date, and subsequent payment dates, will be
extended by the number of days that the achievement of certain milestones under
the Loral Satellite Contract is delayed beyond the dates set forth in the Loral
Satellite Contract. Our fourth, spare, satellite is expected to be delivered to
ground storage in October 2001 and was originally expected to be delivered to
ground storage in October 2000. As a result of Loral's delay in delivering this
satellite, we do not expect to make any required payments with respect to these
deferred amounts until June 2003, at the earliest. We do have the right to
prepay any deferred payments together with accrued interest, without penalty. As
collateral security for these deferred payments, we have granted Loral a
security interest in our terrestrial repeater network.


4.   Long-term Notes Payable


Long-term Notes Payable consists of the following:



                                                           June 30, 2001            December 31, 2000

5.   Commitments and Contingencies

Satellite Contract

         We entered into the Loral Satellite Contract to build and launch the
satellites necessary for our service. We are committed to make aggregate
payments of approximately $745,890 under the Loral Satellite Contract. As of
June 30, 2001, $683,390 of this obligation had been satisfied. Our future
payments due to Loral, including deferred satellite payments, are as follows:
$12,500 in 2001, $0 in 2002, $25,000 in 2003 and $25,000 in 2004. The amount and
timing of these payments depends upon the completion of construction of our
fourth, spare, satellite.

Radio Commitments

         Matsushita Communication Industrial Corporation of USA ("Panasonic")
has constructed a dedicated facility in Peachtree City, Georgia, to manufacture
radios capable of receiving our broadcasts. During the first year of production
of our radios at this facility, we are obligated to purchase certain radios not
purchased by other customers. Based on discussions with potential purchasers of
these radios, including consumer electronics retailers and suppliers to the
automotive industry, we do not expect to incur any costs under this agreement;
however, if Panasonic were unable to sell any of the applicable radios, our
costs could approximate $70,000.

Programming Agreements

         We have entered into agreements with providers of non-music
programming. We are obligated, in certain instances, to pay license fees, share
advertising revenue from this programming or purchase advertising on properties
owned or controlled by these programmers.


6.   Engineering Design and Development

         We have entered into agreements with Agere Systems, Inc. (the successor
to the micro-electronics group of Lucent Technologies, Inc.) to develop and
manufacture integrated circuits ("chip sets") which will be used in radios
capable of receiving our broadcasts. In addition, we have entered into
agreements with Alpine Electronics Inc., Audiovox Corporation, Clarion Co.,
Ltd., Delphi Delco Electronics Systems, Fujitsu Ten Limited, Harman
International Industries, Incorporated, Kenwood Corporation, Mitsubishi Electric
Automotive America, Inc., Panasonic, Pioneer Corporation, Recoton Corporation,
Sanyo Electronic Co. Ltd., Sony Electronics Inc., Visteon Automotive Systems and
other manufacturers to design, develop and produce radios capable of receiving
our broadcasts and have agreed to pay certain costs associated with these
radios. We record expenses under these agreements as work is performed. Total
expenses related to these agreements were $22,183 and $24,990 for the six month
periods ended June 30, 2001 and 2000, respectively, and $96,864 for the period
May 17, 1990 (date of inception) to June 30, 2001.


7.   Stock Option Plans

         In April 2001, the Compensation Committee of our Board of Directors
amended the exercise price of approximately 3,982,000 employee stock options. In
accordance with Financial Accounting Standards Board Interpretation No. 44,
"Accounting for Certain Transactions Involving Stock Compensation," repriced
stock options are subject to variable accounting, which requires a
compensation charge or benefit to be recorded each period based on the market
value of our common stock until the repriced stock options are exercised,
forfeited or expire. We recognized a non-cash compensation charge of $10,083
for the quarter ended June 30, 2001 in connection with the repriced stock
options. We will record non-cash stock compensation charges or benefits based
on the market value of our common stock at the end of future reporting periods.

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, 2000 (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    the unavailability of radios capable of receiving our broadcasts
               and our dependence upon third parties to manufacture and
               distribute them;

          o    the potential risk of delay in implementing our business plan;

          o    the unproven market for our service; and

          o    our need for additional financing.


         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 such forward-looking statements. In addition, any forward-looking statements
speak only as of the date on which such statement is made, and we undertake no
obligation to update any forward-looking statement or statements to reflect
events or circumstances after the date on which such statement is made or to
reflect the occurrence of unanticipated events 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 results to
differ materially from those contained in any forward-looking statements.

Overview

         Sirius Satellite Radio Inc. was organized in May 1990 and is in its
development stage. Our principal activities to date have included:

          o    obtaining regulatory approval for our service;

          o    constructing and launching our three satellite constellation;

          o    constructing our national broadcast studio;

          o    acquiring content for our programming;

          o    constructing our terrestrial repeater network;

          o    arranging for the development of radios capable of receiving our
               broadcasts;

          o    strategic planning and market research;

          o    recruiting our management team; and

          o    securing financing for capital expenditures and working capital.


         We will require additional funds for working capital, interest on
borrowings, financing costs and operating expenses until some time after we
commence commercial operations. We cannot assure you that we will ever commence
commercial operations, attain any particular level of revenues or achieve
profitability.

         We expect to broadcast 50 channels of commercial-free music and up to
50 channels of news, sports and entertainment to consumers throughout the
continental United States and expect our primary source of revenues to be
subscription fees. Our subscription fee will be $12.95 per month, with a
one-time activation fee per subscriber. We also expect our subscription to be
included in the sale or lease of certain new vehicles. In addition, we expect to
derive revenues from directly selling or bartering limited advertising on our
non-music channels.

         The operating expenses associated with our service will consist
primarily of marketing and sales costs, costs to acquire programming, expenses
of operating and maintaining our broadcasting system and general and
administrative costs. Costs to acquire programming include payments to maintain
an extensive music library, royalty payments for broadcasting music and payments
to providers of content for our non-music channels. As of August 8, 2001, we had
204 employees. On December 31, 2001, we expect to have approximately 300
employees.

         We received title to our satellites on July 31, 2000, September 29,
2000 and December 20, 2000, following the completion of in-orbit testing of each
satellite. We expect our fourth, spare, satellite to be delivered to ground
storage in October 2001.

Results of Operations

Three Months Ended June 30, 2001 Compared with Three Months Ended June 30, 2000

         We had net losses of $62,068 and $34,792 for the three months ended
June 30, 2001 and 2000, respectively. Our total operating expenses were $46,652
and $28,868 for the three months ended June 30, 2001 and 2000, respectively.

         Engineering design and development costs were $14,206 and $17,163 for
the three months ended June 30, 2001 and 2000, respectively. These engineering
costs represented primarily payments to Agere Systems, Inc. (53% in the 2001
period and 41% in the 2000 period) and other radio development and manufacturing
partners (11% in the 2001 period and 24% in the 2000 period). The decrease in
costs in the 2001 period was due to lower payments in connection with our chip
set development effort and the completion of most activity relating to the
development of radios capable of receiving our broadcasts.

         General and administrative expenses increased for the three months
ended June 30, 2001 to $20,799 from $9,693 for the three months ended June 30,
2000. General and administrative expenses increased principally due to the
growth of our workforce, operation of our terrestrial repeater network,
depreciation of our broadcast studio equipment and the cost of in-orbit
insurance for our three satellites during the entire 2001 period. The major
components of general and administrative expenses in the 2001 period were
salaries and employment related costs (24%), rent and occupancy costs (16%) and
marketing costs (11%), while in the 2000 period the major components were
salaries and employment related costs (38%), rent and occupancy costs (14%) and
marketing costs (10%). The remaining portion of general and administrative
expenses (49% in the 2001 period and 38% in the 2000 period) consisted of other
costs such as legal and regulatory, insurance, consulting, travel, depreciation
and supplies, with only insurance costs (14%) and depreciation (11%) exceeding
10% of the total in the 2001 period and no such amounts exceeding 10% of the
total in the 2000 period.

         Non-cash stock compensation charge increased for the three months ended
June 30, 2001 to $11,647 from $2,012 for the three months ended June 30, 2000.
The increase in charges in the 2001 period resulted primarily from the charge
associated with the repricing of certain employee stock options in April 2001.
We expect to record future non-cash stock compensation charges or benefits based
on the market value of our common stock at the end of each reporting period.

         The decrease in interest and investment income to $5,769 for the three
months ended June 30, 2001, from $6,595 for the three months ended June 30,
2000, was the result of lower rates of return on our investments in U.S.
government securities and commercial paper issued by major U.S. corporations
during the 2001 period.

         Interest expense was $21,185 for the three months ended June 30, 2001
and $12,519 for the three months ended June 30, 2000, net of capitalized
interest of $4,711 and $20,181, respectively. Gross interest expense for the
2001 period decreased by $6,804 and capitalized interest decreased by $15,470,
compared to the 2000 period. The decrease in gross interest from the prior
period was due to the expense incurred during the 2000 period related to the
induced conversion of our 8-3/4% Convertible Subordinated Notes due 2009; net of
an increase in gross interest during the 2001 period in connection with our term
loan facility. The decrease in the capitalization of interest during the 2001
period was primarily due to the lower level of construction in process
associated with our satellites and launch vehicles.


                                       10








Six Months Ended June 30, 2001 Compared with Six Months Ended June 30, 2000

         We had net losses of $116,157 and $59,603 for the six months ended June
30, 2001 and 2000, respectively. Our total operating expenses were $85,968 and
$55,644 for the six months ended June 30, 2001 and 2000, respectively.

         Engineering design and development costs were $31,765 and $33,974 for
the six months ended June 30, 2001 and 2000, respectively. These engineering
costs represented primarily payments to Agere Systems, Inc. (45% in the 2001
period and 52% in the 2000 period) and other radio development and manufacturing
partners (24% in the 2001 period and 26% in the 2000 period). The decrease in
costs in the 2001 period was due to lower payments in connection with our chip
set development effort and from the completion of most activity relating to the
development of radios capable of receiving our broadcasts.

         General and administrative expenses increased for the six months ended
June 30, 2001 to $41,614 from $17,928 for the six months ended June 30, 2000.
General and administrative expenses increased principally due to the growth of
our workforce, operation of our terrestrial repeater network, depreciation of
our broadcast studio equipment and the cost of in-orbit insurance for our three
satellites during the entire 2001 period. The major components of general and
administrative expenses in the 2001 period were salaries and employment related
costs (23%), rent and occupancy costs (16%) and marketing costs (13%), while in
the 2000 period the major components were salaries and employment related costs
(37%), rent and occupancy costs (16%) and marketing costs (13%). The remaining
portion of general and administrative expenses (48% in the 2001 period and 34%
in the 2000 period) consisted of other costs such as legal and regulatory,
insurance, consulting, travel, depreciation and supplies, with only insurance
(14%) exceeding 10% of the total in the 2001 period and no such amount exceeding
10% of the total in the 2000 period.

         Non-cash stock compensation charge increased for the six months ended
June 30, 2001 to $12,589 from $3,742 for the six months ended June 30, 2000. The
increase in charges in the 2001 period resulted primarily from the charge
associated with the repricing of certain employee stock options in April 2001.
We expect to record future non-cash stock compensation charges or benefits based
on the market value of our common stock at the end of each reporting period.

         The decrease in interest and investment income to $9,376 for the six
months ended June 30, 2001, from $14,426 for the six months ended June 30, 2000,
was the result of a lower average balance of cash, cash equivalents and
marketable securities and lower rates of return on our investments in U.S.
government securities and commercial paper issued by major U.S. corporations
during the 2001 period.

         Interest expense was $39,565 for the six months ended June 30, 2001 and
$18,385 for the six months ended June 30, 2000, net of capitalized interest of
$9,073 and $37,699, respectively. Gross interest expense for the 2001 period
decreased by $7,446 and capitalized interest decreased by $28,626, compared to
the 2000 period. The decrease in gross interest from the prior period was due to
the expense incurred during the 2000 period related to the induced conversion of
our 8-3/4% Convertible Subordinated Notes due 2009; net of an increase in gross
interest during the 2001 period in connection with our term loan facility. The
decrease in the capitalization of interest during the 2001 period was primarily
due to the lower level of construction in process associated with our satellites
and launch vehicles.

Liquidity and Capital Resources

         At June 30, 2001, we had cash, cash equivalents, marketable securities
and restricted investments totaling $444,782 and working capital of $420,877
compared with cash, cash equivalents, marketable securities and restricted
investments totaling $185,060 and working capital of $143,981 at December 31,
2000.

         Funding Requirements. We entered into a satellite contract (the "Loral
Satellite Contract") with Space Systems/Loral, Inc. ("Loral") to build and
launch the satellites necessary to transmit our service. The Loral Satellite
Contract requires Loral to:

     o    construct, launch and deliver three satellites in-orbit and
          checked-out;

     o    construct a fourth satellite for use as a spare; and

     o    deliver $15,000 of long-lead time parts for a possible fifth
          satellite.

We are committed to make aggregate payments of approximately $745,890 under the
Loral Satellite Contract. As of June 30, 2001, $683,390 of this obligation had
been satisfied. Our future payments due to Loral are as follows: $12,500 in
2001, $0 in 2002, $25,000 in 2003 and $25,000 in 2004. The amount and timing of
our future payments to Loral depends upon the completion of construction of our
fourth satellite.

         The amount and timing of our other cash requirements will depend upon
numerous factors, including costs associated with the design and development of
chip sets and radios, the rate of growth of our business after we commence
service, costs of financing and the possibility of unanticipated costs.

         Sources of Funding. To date, we have funded our capital needs through
the issuance of debt and equity securities.

          Convertible Preferred Stock for all the outstanding shares of our 5%
          Delayed Convertible Preferred Stock) (all shares of our 10-1/2% Series

     o    the sale of 11,500,000 shares of our common stock in an underwritten
          public offering (net proceeds of approximately $229,300) in February

As of June 30, 2001, we had received a total of approximately $443,000 in net
proceeds from the following public debt offerings:

     o    12,910 units, each consisting of $20 aggregate principal amount at
          maturity of our 15% Senior Secured Discount Notes due 2007 and a
          warrant to purchase additional 15% Senior Secured Discount Notes due
          2007 with an aggregate principal amount at maturity of $3 in an
          underwritten public offering (net proceeds of approximately $116,000)
          in November 1997. All of these warrants were exercised in 1997. The
          aggregate value at maturity of our 15% Senior Secured Discount Notes
          due 2007 is approximately $297,000. Our 15% Senior Secured Discount
          Notes due 2007 mature on December 1, 2007 and the first cash interest
          payment is due in June 2003.

     o    200,000 units, each consisting of $1 aggregate principal amount of our
          14-1/2% Senior Secured Notes due 2009 and three warrants, each to
          purchase 4.189 shares of our common stock (as of June 30, 2001) in an
          underwritten public offering (net proceeds of approximately $190,000)
          in May 1999. The warrants are exercisable through May 15, 2009 at an
          exercise price of $24.92 per share (as of June 30, 2001). We invested
          approximately $79,300 of the net proceeds from this offering in a
          portfolio of U.S. government securities, which we pledged as security
          for payment in full of interest due on the 14-1/2% Senior Secured
          Notes due 2009 through May 15, 2002.

     o    $125,000 aggregate principal amount of our 8-3/4% Convertible
          Subordinated Notes due 2009 in an underwritten public offering (net
          proceeds of approximately $119,000) in September 1999. In October
          1999, we issued an additional $18,750 aggregate principal amount of
          our 8-3/4% Convertible Subordinated Notes due 2009 to the underwriters
          of that offering in connection with their over-allotment option (net
          proceeds of approximately $18,000).

         The indentures governing our 14-1/2% Senior Secured Notes due 2009 and
our 15% Senior Secured Discount Notes due 2007 contain limitations on our
ability to issue additional debt. These notes are secured by a pledge of
the stock of Satellite CD Radio, Inc., our subsidiary that holds our FCC
license. As of June 30, 2001, we had acquired $62,914 principal amount of our
8-3/4% Convertible Subordinated Notes due 2009 in exchange for shares of our
common stock.

         Loral has deferred a total of $50,000 of payments under the Loral
Satellite Contract originally scheduled for payment in 1999. These deferred
amounts bear interest at 10% per year and were originally scheduled to be paid
in quarterly installments beginning in June 2002. However, the agreement
governing these deferred amounts provides that this date, and subsequent payment
dates, will be extended by the number of days that the achievement of any
milestone under the Loral Satellite Contract is delayed beyond the dates set
forth in the Loral Satellite Contract. Our fourth, spare, satellite was
originally expected to be delivered to ground storage in October 2000 and now is
expected to be delivered to ground storage in October 2001. As a result of this
delay, we do not expect to make any required payments with respect to these
deferred payments until June 2003, at the earliest. As security for these
deferred payments, we have granted Loral a security interest in our terrestrial
repeater network.

         On June 1, 2000, we entered into a term loan agreement with Lehman
Commercial Paper Inc. ("LCPI") and Lehman Brothers Inc. On March 7, 2001, after
satisfaction of the conditions to borrowing, including a demonstration of our
broadcast system, we borrowed $150,000 of term loans from LCPI under this
agreement. These term loans bear interest at an annual rate equal to the
eurodollar rate plus 4% or a base rate, typically the prime rate, plus 5%. These
term loans are secured by a pledge of the stock of Satellite CD Radio, Inc., our
subsidiary that holds our FCC license, and our rights under the Loral Satellite
Contract relating to our fourth, spare, satellite.

         The term loans mature in quarterly installments, commencing on March
31, 2003, in an amount equal to the percentage set forth below of the aggregate
principal amount of the loans:




         Installment                                   Percentage
         -----------                                   ----------
                                                     
         March 31, 2003............................      0.25%
         June 30, 2003.............................      0.25%
         September 30, 2003........................      0.25%
         December 31, 2003.........................      0.25%
         March 31, 2004............................      2.25%
         June 30, 2004.............................      2.25%
         September 30, 2004........................      2.25%
         December 31, 2004.........................      2.25%
         March 31, 2005............................     22.50%
         June 30, 2005.............................     22.50%
         September 30, 2005........................     22.50%
         December 31, 2005.........................     22.50%



         We may prepay the term loans in whole at any time or in part from time
to time. Prepayment prior to March 7, 2004 must be accompanied by a specified
prepayment penalty. We must prepay the term loans:

     o    with the net proceeds of certain incurrences of indebtedness;

     o    with the proceeds of asset sales, subject to certain exceptions; and

     o    commencing with the fiscal year ending December 31, 2002, with excess
          cash.


                                       14








         The term loan facility contains customary covenants and events of
default for a senior secured bank loan. These covenants restrict our ability to
issue additional debt and engage in certain activities.

         In connection with this term loan facility, we granted LCPI 2,100,000
warrants, each to purchase one share of our common stock, at an exercise price
of $29.00 per share.

         Shares of our 9.2% Series A Junior Cumulative Convertible Preferred
Stock and 9.2% Series B Junior Cumulative Convertible Preferred Stock are

or in cash annually, at our option. Holders of our 9.2% Series A Junior
Cumulative Convertible Preferred Stock and 9.2% Series B Junior Cumulative

     o    must be redeemed by us on November 15, 2011.

         As of August 8, 2001, we had sufficient funds to operate our business
through the third quarter of 2002. We will require additional funds to support
our planned operations through the remainder of 2002 and thereafter until our
revenues grow substantially. We plan to fund our additional capital needs
through the issuance of debt and equity securities.
