    2. To ratify the appointment of Arthur Andersen LLP as our independent
       accountants for the current fiscal year.

--------------------------------------------------------------------------------

HOW DO I VOTE?

   If your shares are held in 'street name', through a broker, bank or other
   nominee, that institution will send you separate instructions describing the
   procedure for voting your shares.

   STOCKHOLDERS OF RECORD can vote as follows:

   By Mail: Stockholders should sign, date and return their proxy cards in the
   pre-addressed, postage-paid envelope that is provided.

   At the Meeting: If you attend the Annual Meeting, you may vote in person by
   ballot, even if you have previously returned a proxy card.

--------------------------------------------------------------------------------

WHO IS ENTITLED TO VOTE AND HOW MANY VOTES DO THEY HAVE?

   Holders of our common stock, 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 as of the
   close of business on September 21, 2001 (the 'Record Date') are entitled to
   vote at the Annual Meeting. Each share of our common stock is entitled to one
   vote. Each share of our Series A Junior Preferred Stock and Series B Junior
   Preferred Stock is entitled to three and one-third votes. Each share of our
   Series D Junior Preferred Stock is entitled to 2.9412 votes. As of the Record
   Date, the number of shares outstanding were as follows: 54,094,212 shares of
   common stock; 1,595,707 shares of Series A Junior Preferred Stock; 715,703
   shares of Series B Junior Preferred Stock; and 2,145,688 shares of Series D
   Junior Preferred Stock.

--------------------------------------------------------------------------------

WHAT IS A PROXY?

   A proxy is a person you appoint to vote on your behalf. We are soliciting
   proxies so that all shares of our common stock, Series A Junior Preferred
   Stock, Series B Junior Preferred Stock and Series D Junior Preferred Stock
   may be voted at the Annual Meeting.

--------------------------------------------------------------------------------

WHO AM I DESIGNATING AS MY PROXY?

   You will be designating Patrick L. Donnelly, our Senior Vice President,
   General Counsel and Secretary, and Edward Weber, Jr., our Vice President and
   Controller, as your proxies.

--------------------------------------------------------------------------------

HOW WILL MY PROXY VOTE MY SHARES?

   Your proxy will vote according to your instructions. If you complete your
   proxy instructions but do not indicate your vote on some or all of the
   business matters, your proxy will vote 'FOR' these items. Also, your proxy is
   authorized to vote on any other business that properly comes before the
   Annual Meeting in accordance with the recommendation of the board of
   directors.

                                       1





<Page>


CAN I CHANGE MY VOTE AFTER I RETURN MY PROXY CARD?

   Yes. You may change your vote at any time before your shares are voted at the
   Annual Meeting by:

    Notifying our Corporate Secretary, Patrick L. Donnelly, in writing at Sirius
    Satellite Radio Inc., 1221 Avenue of the Americas, 36th Floor, New York, New
    York 10020 that you are revoking your proxy;

    Executing and delivering a later dated proxy card; or

    Voting in person at the Annual Meeting.

    However, if you have shares held through a brokerage firm, bank or other
    custodian, and you vote by proxy, you may revoke your proxy instructions
    only by informing the custodian in accordance with any procedures it has
    established.
--------------------------------------------------------------------------------

WHAT IS A QUORUM OF STOCKHOLDERS?

   Shares representing the majority of votes, present or represented by proxy,
   constitute a quorum. If you vote, your shares will be considered part of the
   quorum.
--------------------------------------------------------------------------------

WHAT VOTE IS REQUIRED TO APPROVE EACH ITEM?

   Assuming a quorum of stockholders is present at the Annual Meeting, the
   affirmative vote of a plurality of all votes cast is required to elect each
   director and the affirmative vote of a majority of all votes cast is needed
   to approve the appointment of Arthur Andersen LLP as our independent
   accountants.
--------------------------------------------------------------------------------

HOW DO YOU COUNT SHARES THAT AREN'T VOTED FOR THE NOMINEES FOR DIRECTOR, OR
ABSTAIN ON ANY MATTER?

   With respect to the election of directors, votes withheld will be treated as
   shares present for purposes of determining a quorum. Directors are elected by
   a plurality vote, so the six persons receiving the greatest number of votes
   will be elected and withheld votes will not affect the outcome of the
   election.

   With respect to the approval of Arthur Andersen LLP, or any other matter
   properly brought before the meeting, abstentions will be treated as shares
   present for purposes of determining a quorum. Because a majority of the
   shares represented at the meeting and entitled to vote is required for
   approval of these matters, abstentions will have the same effect as a vote
   against approval.
--------------------------------------------------------------------------------

HOW DO YOU COUNT SHARES THAT ARE HELD BY BROKERS BUT NOT VOTED?

   Valid proxies submitted by a broker or its nominee that are not voted on a
   matter or that are marked 'abstain' will be counted for purposes of
   determining a quorum at the Annual Meeting, but will not be considered as
   having voted on that matter.
--------------------------------------------------------------------------------

WHO WILL COUNT THE VOTES?

   A representative of The Bank of New York, our transfer agent, will tabulate
   the votes and act as inspector of election.
--------------------------------------------------------------------------------

HOW DO I ATTEND THE ANNUAL MEETING?

   If you are a registered stockholder, an admission ticket is enclosed with
   your proxy card. If you wish to attend the Annual Meeting, please vote your
   proxy but keep the admission ticket and bring it with you to the Annual
   Meeting.

   If your shares are held in the name of a bank, broker or other holder of
   record and you wish to attend the Annual Meeting, you need to bring a copy of
   a bank or brokerage statement to the Annual Meeting reflecting your stock
   ownership as of the Record Date.

                                       2

WHO IS SOLICITING MY PROXY AND WHO PAYS THE COST?

   Sirius is soliciting your proxy. The cost of soliciting proxies will be borne
   by Sirius, which has engaged Georgeson Shareholder Communications Inc. to
   assist in the distribution and solicitation of proxies. We have agreed to pay
   Georgeson $5,000 plus their reasonable out-of-pocket expenses. Sirius will
   also reimburse brokerage firms, banks and other custodians for their
   reasonable out-of-pocket expenses for forwarding these proxy materials to
   you. Directors, officers and regular employees of Sirius may solicit proxies
   on our behalf by telephone or in writing.

--------------------------------------------------------------------------------

WHEN ARE THE STOCKHOLDER PROPOSALS DUE FOR NEXT YEAR'S ANNUAL MEETING?

   To be eligible for inclusion in our proxy statement and form of proxy for
   next year's annual meeting, stockholder proposals must be submitted in
   writing by the close of business on June 12, 2002 to Patrick L. Donnelly,
   Senior Vice President, General Counsel and Secretary, Sirius Satellite Radio

   If any proposal that is not submitted for inclusion in next year's proxy (as
   described in the preceding paragraph) is instead sought to be presented
   directly at next year's annual meeting, the proxies may vote in their
   discretion if (a) we receive notice of the proposal before the close of
   business on June 12, 2002 and advise stockholders in next year's proxy
   statement about the nature of the matter and how management intends to vote
   on such matter or (b) we do not receive notice of the proposal prior to the
   close of business on June 12, 2002. Notices of intention to present proposals

                        REPORT OF COMPENSATION COMMITTEE

    The Compensation Committee of our board of directors (the 'Committee') is
comprised solely of directors who are not current or former employees. The
Committee is responsible for overseeing and administering our executive
compensation programs. The Committee also reviews, monitors and approves
executive compensation, establishes compensation guidelines for our officers,
reviews projected personnel needs and administers our long-term stock incentive
plan.

COMPENSATION PHILOSOPHY

    Our compensation program for executive officers consists of three key
elements:

     a base salary;

     an annual bonus; and

     grants of stock options.

    The Committee believes that this three-part approach best serves the
interests of our stockholders. It enables us to meet the requirements of the
competitive environment in which we operate while ensuring that executive
officers are compensated in a way that advances both the short and long-term
interests of stockholders. Under this approach, compensation for our executive
officers involves a high proportion of pay that is 'at risk' -- namely, the
annual bonus and the value of stock options. The annual bonus is intended to be
based, in significant part, on individual performance. Stock options relate a
significant portion of long-term remuneration directly to stock price
appreciation realized by stockholders.

BASE SALARIES

    The base salaries paid to each of our executive officers during 2000 were
paid pursuant to the written employment agreements described below, under the
heading 'Employment Agreements'. Changes in base salaries for our executive
officers, other than our Chief Executive Officer, are based upon recommendations
by our Chief Executive Officer, taking into account such factors as competitive
salaries, a subjective assessment of the nature of the position and the
contribution and experience of the officer and the length of the officer's
service. Neither the Committee nor the Chief Executive Officer assigned any
relative weight to the various factors they considered or set predetermined
performance targets for purposes of these base salary determinations. During
2000, Mr. Margolese reviewed all such salary recommendations with the Committee,
and all such recommendations were subject to approval or disapproval by the
Committee. At the recommendation of Mr. Margolese, the Committee approved a base
salary increase for Mr. Capobianco in March 2000 from $250,000 to $275,000 and
approved a base salary increase in December 2000 for Mr. Donnelly from $290,000
to $325,000. Mr. Capobianco's and Mr. Donnelly's base salaries were last
increased in June 1999.

    Except as to the compensation reflected in the Employment Agreement entered
into by us and David Margolese as of January 1, 1999, we have not sought to
position executive compensation within any particular range as compared to any
stated peer group.

ANNUAL BONUS

    In December 2000, the Committee awarded a cash bonus to Mr. Margolese of
$500,000, a cash bonus to Mr. Briskman of $310,000, a cash bonus to Mr.
Capobianco of $275,000, a cash bonus to Dr. Davidov of $162,500 and a cash bonus
to Mr. Donnelly of $323,000. The Committee awarded these bonuses after reviewing
the progress achieved during 2000 in completing our business plan, including the
successful launch of our satellite constellation, our progress in completing our
terrestrial repeater network and radio development effort and the performance of
our common stock during the year relative to other high-tech companies.

STOCK OPTIONS

    We provide long-term incentives through stock options granted to our
executive officers under our long-term stock incentive plan. The Committee
believes that the potential for stock ownership by executives and other
employees is the most effective method by which the interests of management may

                                       6

be aligned with those of our stockholders. The options granted typically vest
over time, have a term of ten years and an exercise price equal to the fair
market value of our common stock on the grant date.

    In January 2000, the Committee awarded Mr. Donnelly 25,000 stock options. In
December 2000, the Committee awarded Mr. Briskman 50,000 stock options, Mr.
Capobianco 50,000 stock options, Mr. Donnelly 50,000 stock options and Dr.
Davidov 50,000 stock options. These options have a ten year term and an exercise
price of $7.50. The number of options granted by the Committee to each executive
officer was based upon such criteria as anticipated achievement,
responsibilities, performance, experience and future potential, as well as an
awareness of the financial incentives required to retain the quality of
executive management essential to the attainment of our strategic and financial
objectives.

    The Committee has authorized executive management to grant stock options to
employees below the executive officer level on an annual basis according to
guidelines intended to be competitive with comparable companies and to reward
individual achievement appropriately. Our executive officers do not receive
annual stock option grants under this program.

COMPENSATION OF OUR CHAIRMAN AND CHIEF EXECUTIVE OFFICER

    In 1998, the Committee negotiated, and we entered into, an employment
agreement with Mr. Margolese, our Chairman and Chief Executive Officer,
effective as of January 1, 1999. The Committee engaged an independent
compensation consultant to assist it in the process of determining appropriate
compensation for Mr. Margolese. This consultant identified for the Committee
peer companies within the telecommunications and technologies industries whose
CEO compensation arrangements served as comparative compensation standards
against which the Committee measured the compensation package (comprised of
annual base salary and stock options) agreed to with Mr. Margolese. Mr.
Margolese's base salary structure under this agreement included annual increases
of $50,000 per year, with a base salary of $500,000 in 2000, over the five-year
term of the agreement. This stepped program of annual base salary increases fell
within the median parameter of the peer group data provided by the consultant.
The stock option grants included within this compensation package reflected the
upper end of the survey data for the peer companies. After due consideration of
this data, Mr. Margolese's performance in achieving our objectives and the level
of his management responsibilities, the Committee concluded that the stock
options granted to Mr. Margolese under this agreement constituted an appropriate
package. Mr. Margolese and Sirius terminated this employment agreement on
October 16, 2001.

POLICY WITH RESPECT TO INTERNAL REVENUE CODE SECTION 162(M)

    Section 162(m) of the Internal Revenue Code places a $1 million per person
limitation on the tax deduction we may take for compensation paid to our Chief
Executive Officer and our four other highest paid executive officers, except
that compensation constituting performance-based compensation, as defined by the
Internal Revenue Code, is not subject to the $1 million limit. The Committee
generally intends to grant awards under our long-term stock incentive plan
consistent with the terms of Section 162(m) so that such awards will not be
subject to the $1 million limit. In other respects, the Committee expects to
take actions in the future that may be necessary to preserve the deductibility
of executive compensation to the extent reasonably practicable and consistent
with other objectives of our compensation program. However, the Committee
reserves the discretion to pay compensation that does not qualify for exemption
under Section 162(m) where the Committee believes such action to be in our best
interest. The Committee believes that the payment to Mr. Margolese described
below under 'Employment Agreements -- Mr. Margolese' relating to his resignation
as Chief Executive Officer will qualify as a tax-deductible expense under
Section 162(m).

SUMMARY

    The Committee believes that our compensation programs are well structured to
encourage attainment of objectives and foster a stockholder perspective in
management through the potential for employee stock ownership. The Committee
believes, further, that the bonuses granted and stock option awards made in 2000
were competitive, appropriate and in our stockholders' long-term interests.

EMPLOYMENT AGREEMENTS

    We are a party to an employment agreement with each of Messrs. Margolese,
Capobianco, Donnelly, Ledford and Scelfo and Dr. Davidov (the 'Employment
Agreements').

MR. MARGOLESE

    Effective January 1, 1999, we entered into a agreement to employ David
Margolese as our Chairman and Chief Executive Officer for a term of five years.
The employment agreement provided for an annual base salary of $500,000 in 2000.
We also granted to Mr. Margolese options to purchase 1,800,000 shares of common
stock at $31.25 per share, all of which were fully vested and exercisable as of
January 1, 2001. Under the terms of the employment agreement, Mr. Margolese may
not disclose any of our proprietary information or, during his employment with
us and for two years thereafter, engage in any business involving the
transmission of radio entertainment programming in North America.

    Mr. Margolese resigned as our Chief Executive Officer on October 16, 2001.
As a result of his resignation, he is entitled to receive a severance payment of
$5,000,000.

    On October 16, 2001, Sirius entered into an agreement with Mr. Margolese in
connection with his continuing responsibilities as non-executive Chairman of the
board of directors. Under this agreement:

     Mr. Margolese will receive, at the discretion of the board, a fee of
     $200,000 per year;

                                       10





<Page>


     The termination date of stock options currently held by Mr. Margolese will
     be extended until April 16, 2007, provided that Mr. Margolese remains
     Chairman of the board of directors and complies with his duties and
     obligations under the agreement; and

     Mr. Margolese's existing employment agreement was cancelled.

    The agreement also contains non-competition and confidentiality provisions
similar to those contained in Mr. Margolese's existing employment agreement.

MESSRS. CAPOBIANCO AND DONNELLY

    On March 28, 2000, we entered into employment agreements with Joseph S.
Capobianco to serve as our Senior Vice President, Content, and Patrick L.
Donnelly, to serve as our Senior Vice President, General Counsel and Secretary.
The agreement with Mr. Capobianco replaced an employment agreement expiring on
April 16, 2000, and the agreement with Mr. Donnelly replaced an employment
agreement expiring on May 18, 2001. Both of these agreements expire on March 28,
2003.

    Pursuant to these agreements, in 2000 we paid Mr. Capobianco an annualized
base salary of $275,000 and Mr. Donnelly an annualized base salary of $290,000.
These base salaries are subject to increase from time to time by our board of
directors. Pursuant to these agreements, if the executive's employment is
terminated, except by us for 'Cause' (as defined in the employment agreements)
or by the executive voluntarily, we are obligated to pay him an amount equal to
the sum of his annual salary and the annual bonus last paid to him. Under these
agreements, neither Mr. Capobianco nor Mr. Donnelly may disclose any of our
proprietary information or, for two years following the termination of his
employment (or, in the event he has been terminated without Cause or has
resigned for 'Good Reason' (as defined in the employment agreements), for one
year following such termination without Cause or resignation for Good Reason),
enter into the employment of, render services to or otherwise assist certain of
our competitors.

DR. DAVIDOV

    On April 17, 2000, we entered into an employment agreement with Dr. Mircho
Davidov to serve as our Senior Vice President, Engineering, for three years.
This agreement provides for an annual base salary of $325,000, subject to
increase from time to time by our board of directors. In connection with this
agreement, we granted Dr. Davidov options to purchase 250,000 shares of our
common stock at $7.50 per share. Options with respect to 62,500 shares became
exercisable on May 15, 2001. The remaining options become exercisable in
increments of 62,500 shares on each of May 15, 2002, May 15, 2003 and May 15,
2004. We also granted Dr. Davidov 40,000 restricted shares of common stock to
replace unvested stock options from his previous employer which terminated as a
result of his becoming employed by us. The restrictions applicable to 35,000
shares of common stock lapsed on May 1, 2001, the restrictions applicable to
3,500 shares of common stock lapse on May 1, 2002 and the restrictions
applicable to the remaining 1,500 shares of common stock lapse on May 1, 2003.
Any unvested stock options will vest and become exercisable, and any
restrictions applicable to the restricted stock will lapse, upon the termination
of Dr. Davidov's employment for any reason other than 'Cause' (as defined in the
employment agreement) or if Dr. Davidov voluntarily terminates his employment.
If Dr. Davidov's employment is terminated, except by us for Cause or by
Dr. Davidov voluntarily, we are obligated to pay him an amount equal to the sum
of his annual salary and the annual bonus last paid to him.

    Pursuant to this agreement, we have also agreed to provide Dr. Davidov
retirement payments in certain circumstances related to the value of his stock
options. Under the agreement, if the gross value of Dr. Davidov's vested stock
options (assuming none of these options have been exercised) does not equal or
exceed $10,000,000 on at least one day during the 365 days preceding Dr.
Davidov's 57th birthday (December 6, 2003), then, if Dr. Davidov is an employee
of the company on his 57th birthday, we are obligated to pay him a pension equal
to 70% of his base salary on his retirement. In addition, if the gross value of
Dr. Davidov's vested stock options (assuming none of these options have been
exercised) does not equal or exceed $15,000,000 on at least one day during the
365 days preceding

                                       11





<Page>


Dr. Davidov's 65th birthday (December 6, 2011), we are obligated to pay him a
pension equal to 100% of his base salary on his retirement.

    Under this agreement, Dr. Davidov may not disclose any of our proprietary
information during or after his employment with us or, for a period of one year
following the date of termination (even if he has been terminated without Cause
or has resigned for Good Reason), enter into the employment of, render services
to, or otherwise assist, certain of our competitors.

MR. SCELFO

    On March 7, 2001, we entered into an employment agreement with John J.
Scelfo to serve as our Senior Vice President and Chief Financial Officer for
three years. This agreement provides for an annual base salary of $300,000,
subject to increase from time to time by our board of directors. In connection
with this agreement, we granted Mr. Scelfo options to purchase 300,000 shares of
our common stock at $6.91 per share. Options with respect to 75,000 shares
became exercisable on October 4, 2001. The remaining options become exercisable
in increments of 75,000 on April 4, 2002, October 4, 2002 and April 4, 2003.

    Pursuant to this agreement, if Mr. Scelfo's employment is terminated, except
by us for 'Cause' (as defined in the employment agreement) or by Mr. Scelfo
voluntarily, we are obligated to pay him an amount equal to the sum of his
annual salary and the annual bonus last paid to him. Under this agreement, Mr.
Scelfo may not disclose any of our proprietary information or, for two years
following the termination of his employment (or, in the event he has been
terminated without Cause or has resigned for 'Good Reason' (as defined in the
employment agreement), for one year following such termination), enter into the
employment of, render services to or otherwise assist our competitors.

MR. LEDFORD

    On August 29, 2001, we entered into an employment agreement with Michael S.
Ledford to serve as our Senior Vice President, Engineering, for three years.
This agreement provides for an annual base salary of $340,000, subject to
increase from time to time by our board of directors. In connection with this
agreement, we granted Mr. Ledford options to purchase 300,000 shares of our
common stock at $4.00 per share. These options become exercisable in increments
of 100,000 shares on each of September 17, 2002, September 17, 2003 and
September 17, 2004. We also granted Mr. Ledford 50,000 restricted shares of
common stock. The restrictions applicable to increments of 12,500 shares of
common stock lapse on September 17, 2002, September 17, 2003, September 17, 2004
and September 17, 2005.

    Pursuant to this agreement, if Mr. Ledford's employment is terminated,
except by us for 'Cause' (as defined in the employment agreement) or by Mr.
Ledford voluntarily, we are obligated to pay him an amount equal to the sum of
his annual salary. Under this agreement, Mr. Ledford may not disclose any of our
proprietary information or, for three years following the termination of his
employment, enter into the employment of, render services to or otherwise assist

VOTING TRUST AGREEMENT

    We are a party to a voting trust agreement dated August 26, 1997 by and
among Darlene Friedland, as grantor, David Margolese, as the voting trustee, and
us. The following summary description of the Voting Trust Agreement does not
purport to be complete and is qualified in its entirety by reference to the
complete text of the agreement.

    The Voting Trust Agreement provides for the establishment of a trust (the
'Trust') into which (i) there has been deposited all of the shares of common
stock owned by Mrs. Friedland on August 26, 1997 and (ii) there shall be
deposited any shares of common stock acquired by Mrs. Friedland, her spouse
Robert Friedland, any member of either of their immediate families or any entity
directly or indirectly controlled by Mrs. Friedland, her spouse or any member of
their immediate families (the 'Friedland Affiliates') between the date shares
are initially deposited and the termination of the Trust. The Voting Trust will
terminate on November 20, 2002.

    The Voting Trust Agreement does not restrict the ability of Mrs. Friedland
or any of the Friedland Affiliates to sell, assign, transfer or pledge any of
the shares deposited into the Trust, nor does it prohibit Mrs. Friedland or the
Friedland Affiliates from purchasing additional shares of our common stock,
provided those shares become subject to the Trust.

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

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

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

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

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

               ITEM 2 -- RATIFICATION OF INDEPENDENT ACCOUNTANTS

    The board of directors has selected Arthur Andersen LLP ('Arthur Andersen')

Meeting. They will have an opportunity to make a statement if they desire to do

                           REPORT OF AUDIT COMMITTEE

    The Audit Committee of the board of directors is comprised of the three
directors named below. Each member of the Audit Committee is an independent
director as defined by the rules of The Nasdaq National Market. The Audit
Committee has adopted a written charter which has been approved by the board of
directors and is set forth in Appendix A.

    The Audit Committee has reviewed and discussed with management our audited
financial statements. Arthur Andersen, our auditor for 2000, is responsible for
expressing an opinion on the conformity of our audited financial statements with
generally accepted accounting principles. The Audit Committee has discussed with
Arthur Andersen the matters that are required to be discussed by Statement on
Auditing Standards No. 61. Arthur Andersen has provided to the Audit Committee
the written disclosures and the letter required by Independence Standards Board
Standard No. 1, and the Audit Committee discussed with Arthur Andersen that
firm's independence. The Audit Committee also considered whether Arthur
Andersen's provision of non-audit services, including financial information
systems design and implementation services to us, is compatible with Arthur
Andersen's independence.

    On the basis of these reviews and discussions, the Audit Committee
recommended to the board of directors that the board approve the inclusion of
our audited financial statements in our Annual Report on Form 10-K for the
fiscal year ended December 31, 2000 for filing with the SEC.

                         CHARTER OF THE AUDIT COMMITTEE

PURPOSE

    The primary purpose of the Audit Committee is to assist the Board of
Directors (the 'Board') in fulfilling its responsibility to oversee management's
conduct of the company's financial reporting process, including the development
and maintenance of systems of internal accounting and financial controls and the
outside auditor's annual audit of the Company's financial statements.

COMPOSITION

    The Committee shall consist of at least three directors, and the Committee's
composition will meet the requirements for audit committees of the Nasdaq:

     No member may have a relationship to the Company that may interfere with
     the exercise of his or her independence from management and the Company;

     Each member shall be financially literate or will become financially
     literate within a reasonable period of time after his or her appointment to
     the Committee; and

     At least one member shall have accounting or related financial management
     expertise.

    The determination of any member's qualification to serve on the audit
committee, including assessments of financial literacy and of past accounting or
financial management expertise, shall be made by the Board in keeping with the
applicable requirements and definitions of the Nasdaq.

RESPONSIBILITIES, INCLUDING STRUCTURE AND PROCESSES

    The Committee's job is one of oversight, recognizing that the Company's
management is responsible for preparing the Company's financial statements and
for developing and maintaining systems of internal accounting and financial
controls and that outside auditors are ultimately accountable to the Committee
and the Board for their review of the financial statements and internal controls
of the Company. The Committee also recognizes that the financial management and
the internal and outside auditors have more knowledge and information about the
Company than do Committee members. Consequently, in carrying out its oversight
responsibilities, the Committee is not providing any expert or special assurance
as to the Company's financial statements or internal controls or any
professional certification as to the outside auditor's work.

    The following functions shall be the common recurring activities of the
Committee in carrying out its oversight responsibilities, and the Committee may,
as it deems appropriate, act as a whole, through subcommittees or through the
Committee chair. In discharging its oversight role, the Committee shall have
full access to all books, records, facilities and personnel of the Company and
the authority to retain outside counsel, auditors or other experts.

     1. The Committee shall review and reassess the adequacy of this Charter on
        an annual basis and shall make recommendations to the Board, as
        conditions dictate, to update this Charter.

     2. The Committee shall have the responsibility to evaluate the outside
        auditor annually and to make recommendations to the Board concerning its
        appointment. The Board shall have the ultimate authority and
        responsibility to select, evaluate and, where appropriate, replace the
        outside auditor.

     3. The Committee shall review and approve the appointment or termination of
        the Company's Controller and any internal auditor.

     4. The Committee shall meet regularly with the Company's Controller and
        outside auditors independent of management.

     5. The Committee shall review and discuss with management the audited
        financial statements to be included in the Company's Annual Report on
        Form 10-K (or the Annual Report to Stockholders if distributed prior to
        the filing of Form 10-K) and shall discuss with the outside

                                      A-1





<Page>


        auditor the matters required to be discussed by Statement of Auditing
        Standards ('SAS') No. 61, as amended or supplemented.

     6. In connection with the review by the outside auditors of the financial
        information included in the Company's Quarterly Reports on Form 10-Q,
        the Committee shall, prior to the release of earnings or the filing of
        the Form 10-Q, discuss with the outside auditors the matters required to
        be discussed by SAS No. 61, as amended or supplemented.

     7. The Committee shall review any significant disagreement between
        management and the internal or outside auditors in connection with the
        preparation of the financial statements.

     8. The Committee shall:

        receive from the outside auditors, at least annually, a formal written
        statement delineating all relationships between the auditor and the
        Company consistent with Independence Standards Board Standard Number 1;

        review and discuss with the outside auditors any relationships or
        services that may impact the objectivity and independence of the outside
        auditor; and

        recommend, if necessary, that the Board take appropriate action in
        response to the outside auditor's report to satisfy itself of the
        auditor's independence.

     9. Based on the review and discussions referred to in paragraphs 5
        through 8, the Committee shall determine whether to recommend to the
        Board that the Company's audited financial statements be included in the
        Company's Annual Report on Form 10-K.

    10. The Committee shall prepare its report required by the rules of the
        Securities and Exchange Commission to be included in the Company's
        annual proxy statement.

    11. The Committee shall discuss with management, the Company's Controller,
        and the outside auditor the quality and adequacy of the Company's
        internal controls.

    12. The Committee shall receive reports on legal compliance and litigation
        matters and review the significant reports as well as management's
        responses thereto.

    13. The Committee shall review and make recommendations to the Board
        concerning the Company's policies with regard to affiliate transactions
        and officers' expense accounts and perquisites.

    14. The Committee shall maintain minutes or other record of its meetings and
        make reports on its meetings to the Board.

                                      A-2
