1. Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, each of the Underwriters that:

(a) The Company has filed with the Securities and Exchange Commission (the “Commission”) registration statements on Form S-3 (No. 333-89132, No. 333-102966 and No. 333-106824) and amendments thereto, and related preliminary prospectuses for the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the Shares which registration statements, as so amended (including post-effective amendments, if any), have been declared effective by the Commission and copies of which have heretofore been delivered

to the Underwriters. The registration statements, as amended at or after the time they became effective, including the prospectuses, financial statements, schedules, exhibits and information (if any) deemed to be part of the registration statements at the time of effectiveness pursuant to Rule 430A or 434(d) under the Securities Act, are hereinafter referred to as the “Registration Statements.” If the Company has filed or is required pursuant to the terms hereof to file a registration statement or registration statements pursuant to Rule 462(b) under the Securities Act registering additional shares of Common Stock (a “Rule 462(b) Registration Statement”), then, unless otherwise specified, any reference herein to the term “Registration Statements” shall be deemed to include any such Rule 462(b) Registration Statement. Other than a Rule 462(b) Registration Statement, which, if filed, becomes effective upon filing, no other document with respect to the Registration Statements has heretofore been filed with the Commission. All of the Shares have been registered under the Securities Act pursuant to the Registration Statements or, if any Rule 462(b) Registration Statement is filed, will be duly registered under the Securities Act with the filing of such Rule 462(b) Registration Statement. No stop order suspending the effectiveness of either the Registration Statements or the Rule 462(b) Registration Statement or Registration Statements, if any, has been issued and no proceeding for that purpose has been initiated or threatened by the Commission. The Company, if required by the rules and regulations of the Commission under the Securities Act (the “Securities Act Regulations”), proposes to file the Prospectus Supplement with the Commission pursuant to Rule 424(b) under the Securities Act (“Rule 424(b)”). The Prospectus, in the form in which it was filed with the Commission in the Registration Statement pursuant to Rule 415 of the Securities Act Regulations, is hereinafter referred to as the “Prospectus.” The Prospectus Supplement relating to the Shares for use in connection with the offering and sale of the Shares, in the form in which it is to be filed with the Commission pursuant to Rule 424(b) of the Securities Act Regulations, is hereinafter referred to as the “Prospectus Supplement.” References to the term “Prospectus Supplement,” unless otherwise indicated, shall refer to the Prospectus and the Prospectus Supplement. Any preliminary prospectus supplement relating to the Shares or prospectus supplement subject to completion relating to the Shares included in the Registration Statement or filed with the Commission pursuant to Rule 424(b) under the Securities Act is hereafter called a “Preliminary Prospectus Supplement.” All references in this Agreement to the Registration Statements, the Rule 462(b) Registration Statement, the Prospectus, a Preliminary Prospectus Supplement and the Prospectus Supplement, or any amendments or supplements to any of the foregoing, shall be deemed to include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System.

(b) The Registration Statements and the Prospectus, at the time the Registration Statements became effective and as of the Closing Date referred to in Section 3 hereof, the Prospectus Supplement, as of the date hereof and as of the Closing Date, and the Preliminary Prospectus Supplement as of the date thereof, complied and comply in all material respects with the requirements of the Securities Act and the Securities Act Regulations, and each of the foregoing did not and as of the Closing Date do not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading. The Prospectus Supplement, as of the date hereof (unless the term “Prospectus Supplement” refers to a prospectus supplement which has been provided to the Underwriters by the Company for use in connection with the offering of the Shares which differs from the Prospectus Supplement filed with the Commission pursuant to Rule 424(b) of the Securities Act Regulations, in which case at the time it is first provided to the Underwriters

for such use) and on the Closing Date, do not and will not include any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the representations and warranties in this Section (1)(b) shall not apply to statements in or omissions from the Registration Statements or Prospectus Supplement made in reliance upon and in conformity with information relating to any Underwriter furnished to the Company in writing by any Underwriter expressly for use in the Registration Statements or the Prospectus Supplement. The parties acknowledge and agree that such information provided by or on behalf of any Underwriter consists solely of the material included in paragraphs 5, 8, 9, 10 and 12 under the caption “Underwriting” in the Prospectus Supplement. Each Preliminary Prospectus Supplement and Prospectus Supplement filed as part of the Registration Statements, as part of any amendment thereto or pursuant to Rule 424 under the Securities Act Regulations, if filed by electronic transmission pursuant to Regulation S-T under the Securities Act, was identical to the copy thereof delivered to the Underwriters for use in connection with the offer and sales of the Shares (except as may be permitted by Regulation S-T under the Securities Act). There are no contracts or other documents required to be described in the Prospectus Supplement or to be filed as exhibits to the Registration Statements under the Securities Act that have not been described or filed therein as required, and there are no business relationships or related-party transactions involving the Company or any of its subsidiaries or any other person required to be described in the Prospectus Supplement that have not been described therein as required.

(c) Each of the Company and its subsidiaries (i) has been duly organized and is validly existing as a corporation in good standing under the laws of its respective jurisdiction of incorporation, (ii) has all requisite corporate power and authority to carry on its business as it is currently being conducted and as described in the Prospectus Supplement and to own, lease and operate its properties, and (iii) is duly qualified and in good standing as a foreign corporation authorized to do business in each jurisdiction in which the nature of its business or its ownership or leasing of property requires such qualification except, with respect to clauses (i) (as it relates to good standing) and (iii), where the failure to be so qualified or in good standing does not and could not reasonably be expected to (x) individually or in the aggregate, result in a material adverse effect on the properties, business, results of operations, condition (financial or otherwise), affairs or prospects of the Company and its subsidiaries, taken as a whole, (y) interfere with or adversely affect the issuance or marketability of the Shares pursuant hereto or (z) in any manner draw into question the validity of this Agreement or the transactions described in the Prospectus Supplement under the caption “Use of Proceeds” (any of the events set forth in clauses (x), (y) or (z), a “Material Adverse Effect”).

(d) All of the outstanding shares of capital stock of the Company have been duly authorized, validly issued, and are fully paid and nonassessable and were not issued in violation of any preemptive or similar rights. The Shares, when issued, delivered and sold in accordance with this Agreement, will be duly authorized and validly issued, fully paid and nonassessable, and will not have been issued in violation of or subject to any preemptive or similar rights. At September, 2003, the Company had the Actual, Pro Forma and Pro Forma As Adjusted For Redemption capitalization as set forth in the Prospectus Supplement under the caption “Capitalization” (subject in each case to the assumptions set forth above such caption). As of December 31, 2003, the Company had 160,655,194 shares of Class A Common Stock outstanding, zero shares of Class B common stock outstanding, 10,786,504 shares of Series A

convertible preferred stock outstanding, 474,289 shares of Series B convertible redeemable preferred stock outstanding, 140,000 shares of Series C convertible redeemable preferred stock outstanding, zero shares of Series D junior participating preferred stock outstanding, options to purchase 11,963,206 shares of Class A common stock outstanding and warrants to purchase 29,581,413 shares of Class A common stock outstanding.

(e) Except as disclosed in the Prospectus Supplement, all of the outstanding capital stock of, or other ownership interests in, the Company’s subsidiaries is owned by the Company, free and clear of any security interest, claim, lien, limitation on voting rights or encumbrance; and all such securities have been duly authorized, validly issued, and are fully paid and nonassessable and were not issued in violation of any preemptive or similar rights.

(f) Except as disclosed in the Prospectus Supplement there are not currently, and will not be as a result of the Offering, any outstanding subscriptions, rights, warrants, calls, commitments of sale or options to acquire or instruments convertible into or exchangeable for, any capital stock or other equity interest of the Company or any of its subsidiaries (other than options issued pursuant to the Company’s 1998 Shares Award Plan and Employee Stock Purchase Plan).

(g) The Common Stock (including the Shares) is registered pursuant to Section 12(g) of the Securities Exchange Act of 1934 (the “Exchange Act”) and is listed for quotation on the Nasdaq National Market System (“Nasdaq”), and the Company has taken no action designed to, or likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act or delisting the Common Stock from Nasdaq, nor has the Company received any notification that the Commission or Nasdaq is contemplating terminating such registration or listing.

(h) The Company has all requisite corporate power and authority to execute, deliver and perform its obligations under this Agreement and to consummate the transactions contemplated hereby, including, without limitation, the corporate power and authority to issue, sell and deliver the Shares as provided herein and the corporate power to effect the Use of Proceeds as described in the Prospectus Supplement.

(i) The statistical and market-related data included in the Prospectus Supplement are based on or are derived from sources which the Company believes to be reliable and accurate in all material respects.

(j) This Agreement has been duly and validly authorized, executed and delivered by the Company and is the legal, valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization or similar laws affecting the rights of creditors generally and subject to general principles of equity, and except insofar as indemnification and contribution provisions may be limited by applicable law or equitable principles.

(k) Neither the Company nor any of its subsidiaries is, nor after giving effect to the Offering will be, (i) in violation of its certificate of incorporation or bylaws, (ii) in

default in the performance of any bond, debenture, note, indenture, mortgage, deed of trust or other agreement or instrument to which it is a party or by which it is bound or to which any of its properties is subject, or (iii) in violation of any local, state or federal law, statute, ordinance, rule, regulation, requirement, judgment or court decree (including, without limitation, the Communications Act of 1934 (the “Communications Act”) and the rules and regulations of the Federal Communications Commission (the “FCC”), and environmental laws, statutes, ordinances, rules regulations, judgments or court decrees) applicable to the Company or any of its subsidiaries or any of their assets or properties (whether owned or leased) other than, in the case of clauses (ii) and (iii), any default or violation that (A) could not reasonably be expected to have a Material Adverse Effect or (B) which is disclosed in the Prospectus Supplement. There exists no condition that, with notice, the passage of time or otherwise, would constitute a default under any such document or instrument, except as disclosed in the Prospectus or Prospectus Supplement .

(l) None of (i) the execution, delivery or performance by the Company of this Agreement, (ii) the issuance and sale of the Shares and (iii) consummation by the Company of the transactions contemplated hereby and in the Prospectus Supplement violate, conflict with or constitute a breach of any of the terms or provisions of, or a default under (or an event that with notice or the lapse of time, or both, would constitute a default), or require consent under, or result in the imposition of a lien on any properties of the Company or any of its subsidiaries, or an acceleration of any indebtedness of the Company or any of its subsidiaries pursuant to, (A) the certificate of incorporation or bylaws of the Company or any of its subsidiaries, (B) any bond, debenture, note, indenture, mortgage, deed of trust, contract or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or its subsidiaries or their properties is or may be bound, (C) any statute, rule or regulation applicable to the Company or any of its subsidiaries or any of their assets or properties or (D) any judgment, order or decree of any court or governmental agency or authority having jurisdiction over the Company or any of its subsidiaries or any of their assets or properties, other than, in the case of clause (B) above, any default or violation that (1) could not reasonably be expected to have a Material Adverse Effect or (2) which is disclosed in the Prospectus Supplement. No consent, approval, authorization or order of, or filing, registration, qualification, license or permit of or with, (i) any court or governmental agency, body or administrative agency or (ii) any other person is required for (A) the execution, delivery and performance by the Company of this Agreement, (B) the issuance and sale of the Shares and the transactions contemplated hereby and thereby except such as have been obtained and made under the Securities Act and state securities or Blue Sky laws and regulations or such as may be required by the National Association of Securities Dealers, Inc. (the “NASD”).

(m) There is (i) no action, suit or proceeding before or by any court, arbitrator or governmental agency, body or official, domestic or foreign, now pending or, to the best knowledge of the Company or any of its subsidiaries, threatened or contemplated to which the Company or any of its subsidiaries is a party or to which the business or property of the Company or any of its subsidiaries is subject, (ii) no statute, rule, regulation or order that has been enacted, adopted or issued by any governmental agency or that has been proposed by any governmental body or (iii) no injunction, restraining order or order of any nature by a federal or state court or foreign court of competent jurisdiction to which the Company or any of its subsidiaries is or may be subject or to which the business, assets, or property of the Company or

any of its subsidiaries are or may be subject, that, in the case of clauses (i), (ii) and (iii) above, (A) is required to be disclosed in the Prospectus Supplement and that is not so disclosed, or (B) except as has been disclosed in the Prospectus Supplement could reasonably be expected to, individually or in the aggregate, result in a Material Adverse Effect.

(n) No action has been taken and no statute, rule, regulation or order has been enacted, adopted or issued by any governmental agency that prevents the issuance of the Shares or prevents or suspends the use of the Prospectus Supplement; no injunction, restraining order or order of any kind by a federal or state court of competent jurisdiction has been issued that prevents the issuance of the Shares, prevents or suspends the sale of the Shares in any jurisdiction referred to in Section 1(c) hereof or that could adversely affect the consummation of the transactions contemplated by this Agreement or the Prospectus Supplement; and every request of any securities authority or agency of any jurisdiction for additional information has been complied with in all material respects.

(o) There is (i) no significant unfair labor practice complaint pending against the Company or any of its subsidiaries nor, to the best knowledge of the Company, threatened against any of them, before the National Labor Relations Board, any state or local labor relations board or any foreign labor relations board, and no significant grievance or significant arbitration proceeding arising out of or under any collective bargaining agreement is so pending against the Company or any of its subsidiaries nor, to the best knowledge of the Company, threatened against any of them, (ii) no significant strike, labor dispute, slowdown or stoppage pending against the Company or any of its subsidiaries nor, to the best knowledge of the Company, threatened against the Company or any of its subsidiaries and (iii) to the best knowledge of the Company, no union representation question existing with respect to the employees of the Company or any of its subsidiaries that, in the case of clauses (i), (ii) or (iii) above, could reasonably be expected to result in a Material Adverse Effect. To the best knowledge of the Company, no collective bargaining organizing activities are taking place with respect to the Company or any of its subsidiaries. None of the Company or any of its subsidiaries has violated (A) any federal, state or local law or foreign law relating to discrimination in hiring, promotion or pay of employees, (B) any applicable wage or hour laws or (C) any provision of the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”), which in the case of clause (A), (B) or (C) above could reasonably be expected to result in a Material Adverse Effect.

(p) None of the Company or any of its subsidiaries has violated any environmental, safety or similar law or regulation applicable to it or its business or property relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental Laws”), lacks any permit, license or other approval required of it under applicable Environmental Laws or is violating any term or condition of such permit, license or approval, which could reasonably be expected to, either individually or in the aggregate, have a Material Adverse Effect.

(q) Each of the Company and its subsidiaries has (i) good and marketable title to all of the properties and assets described in the Prospectus Supplement as owned by it, free and clear of all liens, charges, encumbrances and restrictions, except such as are described in

the Prospectus Supplement or as would not have a Material Adverse Effect, (ii) peaceful and undisturbed possession of its properties under all material leases to which it is a party as lessee, (iii) all licenses, certificates, permits, authorizations, approvals, franchises and other rights from, and has made all declarations and filings with, all federal, state and local authorities, all self-regulatory authorities and all courts and other tribunals (each an “Authorization”) necessary to engage in the business conducted by it in the manner described in the Prospectus Supplement, except as described in the Prospectus Supplement or where failure to hold such Authorizations would not, individually or in the aggregate, have a Material Adverse Effect and (iv) no reason to believe that any governmental body or agency is considering limiting, suspending or revoking any such Authorization. Except where the failure to be in full force and effect would not have a Material Adverse Effect, all such Authorizations are valid and in full force and effect, and each of the Company and its subsidiaries is in compliance in all material respects with the terms and conditions of all such Authorizations and with the rules and regulations of the regulatory authorities having jurisdiction with respect thereto. All material leases to which the Company or any of its subsidiaries is a party are valid and binding, and no default by the Company or any subsidiary has occurred and is continuing thereunder and, to the best knowledge of the Company and its subsidiaries, no material defaults by the landlord are existing under any such lease that could reasonably be expected to result in a Material Adverse Effect.

(r) Each of the Company and its subsidiaries owns, possesses or has the right to employ all patents, patent rights, licenses (including all FCC, state, local or other regulatory licenses), inventions, copyrights, know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, software, systems or procedures), trademarks, service marks and trade names, inventions, computer programs, technical data and information (collectively, the “Intellectual Property”) presently employed by it in connection with the businesses now operated by it or that are proposed to be operated by it or its subsidiaries free and clear of and without violating any right, claimed right, charge, encumbrance, pledge, security interest, restriction or lien of any kind of any other person and none of the Company or any of its subsidiaries has received any notice of infringement of or conflict with asserted rights of others with respect to any of the foregoing, except as (1) disclosed in the Prospectus Supplement or (2) as could not reasonably be expected to have a Material Adverse Effect. To the best knowledge of the Company, the use of the Intellectual Property in connection with the business and operations of the Company and its subsidiaries does not infringe on the rights of any person, except as disclosed in the Prospectus Supplement or as could not reasonably be expected to have a Material Adverse Effect.

(s) None of the Company or any of its subsidiaries or, to the best knowledge of the Company, any of their respective officers, directors, partners, employees, agents or affiliates or any other person acting on behalf of the Company or any of its subsidiaries has, directly or indirectly, given or agreed to give any money, gift or similar benefit (other than legal price concessions to customers in the ordinary course of business) to any customer, supplier, employee or agent of a customer or supplier, official or employee of any governmental agency (domestic or foreign), instrumentality of any government (domestic or foreign) or any political party or candidate for office (domestic or foreign) or other person who was, is or may be in a position to help or hinder the business of the Company or any of its subsidiaries (or assist the Company or any of its subsidiaries in connection with any actual or proposed transaction), which (i) might subject the Company or any of its subsidiaries, or any other individual or entity, to any

damage or penalty in any civil, criminal or governmental litigation or proceeding (domestic or foreign), (ii) if not given in the past, might have had a Material Adverse Effect or (iii) if not continued in the future, might have a Material Adverse Effect.

(t) All material tax returns required to be filed by the Company and each of its subsidiaries in all jurisdictions have been so filed. All taxes, including withholding taxes, penalties and interest, assessments, fees and other charges due or claimed to be due from such entities or that are due and payable have been paid, other than those being contested in good faith and for which adequate reserves have been provided or those currently payable without penalty or interest. To the knowledge of the Company, there are no material proposed additional tax assessments against the Company, the assets or property of the Company or any of its subsidiaries. The Company has made adequate charges, accruals and reserves in the applicable financial statements included in the Prospectus Supplement in respect of all federal, state and foreign income and franchise taxes for all periods as to which the tax liability of the Company or any of its consolidated subsidiaries has not been finally determined.

(u) None of the Company or any of its subsidiaries is (i) an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended (the “Investment Company Act”), or (ii) a “holding company” or a “subsidiary company” or an “affiliate” of a holding company within the meaning of the Public Utility Holding Company Act of 1935, as amended.

(v) Except as disclosed in the Prospectus Supplement, there are no holders of securities of the Company or any of its subsidiaries who, by reason of the execution by the Company of this Agreement to which it is a party or the consummation by the Company or any of its subsidiaries of the transactions contemplated hereby, have the right to request or demand that the Company or any of its subsidiaries register under the Securities Act or analogous foreign laws and regulations securities held by them, other than such that have been duly waived.

(w) Each of the Company and its subsidiaries maintains a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences thereto.

(x) Except as disclosed in the Prospectus Supplement, each of the Company and its subsidiaries maintains insurance covering its properties, operations, personnel and businesses. Such insurance insures against such losses and risks as are adequate in accordance with customary industry practice to protect the Company and its subsidiaries and their respective businesses. None of the Company or any of its subsidiaries has received notice from any insurer or agent of such insurer that substantial capital improvements or other expenditures will have to be made in order to continue such insurance. All such insurance is outstanding and duly in force on the date hereof, subject only to changes made in the ordinary course of business, consistent with past practice, which do not, singly or in the aggregate,

materially alter the coverage thereunder or the risks covered thereby. The Company has no reason to believe that it or any subsidiary will not be able (a) to renew its existing insurance coverage as and when such policies expire or (b) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted or as presently contemplated and at a cost that would not result in a Material Adverse Effect.

(y) None of the Company or any of its subsidiaries has (i) taken, directly or indirectly, any action designed to, or that might reasonably be expected to, cause or result in stabilization or manipulation of the price of any security of the Company or any of its subsidiaries to facilitate the sale or resale of the Shares or (ii) since the date of the Preliminary Prospectus Supplement (A) sold, bid for, purchased or paid any person any compensation for soliciting purchases of, the Shares or (B) paid or agreed to pay to any person any compensation for soliciting another to purchase any other securities of the Company or any of its subsidiaries.

(z) The Company and its subsidiaries and any “employee benefit plan” (as defined under ERISA) established or maintained by the Company, its subsidiaries or their “ERISA Affiliates” (as defined below) are in compliance in all material respects with ERISA. “ERISA Affiliate” means, with respect to the Company or a subsidiary, any member of any group of organizations described in Sections 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (the “Code”) of which the Company or such subsidiary is a member. No “reportable event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates. No “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined under ERISA). Neither the Company, its subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code. Each “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, which would cause the loss of such qualification.

(aa) Subsequent to the respective dates as of which information is given in the Prospectus Supplement and up to the Closing Date, except as set forth in the Prospectus Supplement, (i) none of the Company or any of its subsidiaries has incurred any liabilities or obligations, direct or contingent, that are material, individually or in the aggregate, to the Company and its subsidiaries taken as a whole, nor entered into any transaction not in the ordinary course of business, (ii) none of the Company or any of its subsidiaries has incurred any liabilities or obligations, direct or contingent, that will be material to the Company and its subsidiaries taken as a whole, (iii) there has not been, singly or in the aggregate, any change or development that could reasonably be expected to result in a Material Adverse Effect, (iv) except for the dividend consisting of shares of Class A Common Stock awarded to the holders of the Company’s Series B convertible redeemable preferred stock on January 9, 2004, there has been no dividend or distribution of any kind declared, paid or made by the Company or any of its subsidiaries on any class of its capital stock, (v) there has been no change in accounting methods

or practices (including any change in depreciation or amortization policies or rates) by the Company or any of its subsidiaries, (vi) there has been no revaluation by the Company or any of its subsidiaries of any of their assets, (vii) there has been no increase in the salary or other compensation payable or to become payable by the Company or any of its subsidiaries to any of their officers, directors, employees or advisors, nor any declaration, payment or commitment or obligation of any kind for the payment by the Company or any of its subsidiaries of a bonus or other additional salary or compensation to any such person, (viii) there has been no amendment or termination of any material contract, agreement or license to which the Company or any subsidiary is a party or by which it is bound, (ix) there has been no waiver or release of any material right or claim of the Company or any subsidiary, including any write-off or other compromise of any material account receivable of the Company or any subsidiary, and (x) there has been no material change in pricing or royalties set or charged by the Company or any subsidiary to their respective customers or licensees or in pricing or royalties set or charged by persons who have licensed Intellectual Property Rights to the Company or any of its subsidiaries.

Such financial statements have been prepared in conformity with generally accepted accounting principles applied on a consistent basis throughout the periods involved, except as may be expressly stated in the related notes thereto. The financial data set forth in the Prospectus Supplement under the captions “Summary—Summary Consolidated Financial Data,” “Selected Financial Data” and “Capitalization,” and the financial data schedule set forth in the Registration Statement fairly present the information set forth therein on a basis consistent with that of the audited financial statements contained in the Prospectus Supplement.

If the Company elects to rely on Rule 434, the Company will prepare and file a term sheet that complies with the requirements of Rule 434, and the Prospectus Supplement shall not be “materially different” (as such term is used in Rule 434) from the Prospectus included in the Registration Statements at the time it became effective.

The Company will notify you and the Selling Stockholders immediately (and, if requested by the Lead Managers, will confirm such notice in writing) (A) when any post-effective amendment to the Registration Statements become effective, (B) of any request by the Commission for any amendment of or supplement to the Registration Statements or the Prospectus Supplement or for any additional information, (C) of the mailing or the

(k) No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any federal, state or foreign governmental or regulatory authority that would, as of the Closing Date, prevent the issuance or sale of the Shares; and no injunction or order of any federal, state or foreign court shall have been issued that would, as of the Closing Date, prevent the issuance or sale of the Shares.

(l) The Company shall have furnished the Underwriters and Underwriters’ Counsel with such other certificates, opinions or other documents as they may have reasonably requested.

(m) At the Closing Date, you shall have received a certificate of an authorized representative of the Selling Stockholders, dated the Closing Date, to the effect that the representations and warranties of the Selling Stockholders set forth in Section 2 hereof are accurate and that each of the Selling Stockholders has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date.

(n) On or prior to the Closing Date, you shall have received a properly completed and executed United States Treasury Department Form W-9 (or other applicable form

or statement specified by Treasury Department regulations in lieu thereof) from each Selling Stockholder.

(o) If any of the conditions specified in this Section 7 shall not have been fulfilled when and as required by this Agreement, or if any of the certificates, opinions, written statements or letters furnished to you or to Underwriters’ Counsel pursuant to this Section 7 shall not be reasonably satisfactory in form and substance to the Lead Managers and to Underwriters’ Counsel, all obligations of the Underwriters hereunder may be cancelled by the Lead Managers at, or at any time prior to, the Closing Date and the obligations of the Underwriters to purchase the Additional Shares may be cancelled by the Lead Managers at, or at any time prior to, the Additional Closing Date. Notice of such cancellation shall be given to the Company in writing, or by telephone. Any such telephone notice shall be confirmed promptly thereafter in writing.

8. Indemnification

(a) The Company shall indemnify and hold harmless each Selling Stockholder and each Underwriter and each person, if any, who controls any Selling Stockholder or Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to attorneys’ fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statements, as originally filed or any amendment thereof, or any related Preliminary Prospectus Supplement or the Prospectus Supplement, or in any supplement thereto or amendment thereof, or (ii) arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Company will not be liable in any such case to the extent but only to the extent that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Lead Managers or Selling Stockholders, as the case may be, expressly for use therein. The parties agree that such information provided by or on behalf of any Underwriter through the Lead Managers consists solely of the material referred to in Section 1(b) hereof and that such information provided by or on behalf of any Selling Stockholder consists solely of the information pertaining to the number of shares beneficially owned by such Selling Stockholder as set forth in the table under the heading “Principal and Selling Stockholders” of the Prospectus Supplement. This indemnity agreement will be in addition to any liability that the Company may otherwise have, including but not limited to other liability under this Agreement. The foregoing indemnity agreement with respect to any Preliminary Prospectus shall not inure to the benefit of any Underwriter who failed to deliver a Prospectus (as then amended or supplemented, provided by the Company to the several Underwriters in the requisite quantity and on a timely basis to permit proper delivery on or prior to the Closing Date) to the person asserting any losses, claims, damages and liabilities and judgments caused by any

untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, if such material misstatement or omission or alleged material misstatement or omission was cured, as determined by a court of competent jurisdiction in a decision not subject to further appeal, in such Prospectus and such Prospectus was required by law to be delivered at or prior to the written confirmation of sale to such person.

(b) Each Selling Stockholder severally and not jointly shall indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to reasonable attorneys’ fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact relating to a Selling Stockholder contained in the Registration Statement for the registration of the Shares, as originally filed or any amendment thereof, or any related Preliminary Prospectus Supplement or the Prospectus Supplement, or in any supplement thereto or amendment thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact relating to such Selling Stockholder required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Selling Stockholders will be liable in any such case to the extent but only to the extent that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Selling Stockholder as described in clause (a) of this Section 8; and; provided further, however, that in no such case shall any Selling Stockholder be liable or responsible for any amount in excess of the proceeds (net of underwriting discounts and commissions but before deducting other expenses) applicable to the Shares sold by such Selling Stockholder pursuant to the transactions contemplated hereby. This indemnity agreement will be in addition to any liability that any Selling Stockholder may otherwise have, including under this Agreement.

(c) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, each Selling Stockholder, each of the directors of the Company and each of the directors of the Selling Stockholders, each of the officers of the Company who shall have signed the Registration Statements, each of the executive officers of the Selling Stockholders, and each other person, if any, who controls the Company or any Selling Stockholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to attorneys’ fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or

actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statements, as originally filed or any amendment thereof, or any related Preliminary Prospectus Supplement or the Prospectus Supplement, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Lead Managers specifically for use therein; provided, however, that in no case shall any Underwriter be liable or responsible for any amount in excess of the underwriting discount applicable to the Shares to be purchased by such Underwriter hereunder. The parties agree that such information provided by or on behalf of any Underwriter through the Lead Managers consists solely of the material referred to in Section 1(b) hereof. This indemnity will be in addition to any liability that any Underwriter may otherwise have, including but not limited to other liability under this Agreement.

(d) Promptly after receipt by an indemnified party under subsection (a), (b) or (c) above of notice of any claims or the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the claim or the commencement thereof (but the failure so to notify an indemnifying party shall not relieve the indemnifying party from any liability which it may have under this Section 8 to the extent that it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability that such indemnifying party may have otherwise than on account of the indemnity agreement hereunder). In case any such claim or action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate, at its own expense in the defense of such action, and to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party; provided however, that counsel to the indemnifying party shall not (except with the written consent of the indemnified party) also be counsel to the indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, (iii) the indemnifying party does not diligently defend the action after assumption of the defense, or (iv) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties. No indemnifying party shall, without the prior written consent of the indemnified parties, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened claim, investigation, action or proceeding in respect of

which indemnity or contribution may be or could have been sought by an indemnified party under this Section 8 or Section 9 hereof (whether or not the indemnified party is an actual or potential party thereto), unless (x) such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such claim, investigation, action or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or any failure to act, by or on behalf of the indemnified party, and (y) the indemnifying party confirms in writing its indemnification obligations hereunder with respect to such settlement, compromise or judgment.

9. Contribution. In order to provide for contribution in circumstances in which the indemnification provided for in Section 8 hereof is for any reason held to be unavailable from any indemnifying party or is insufficient to hold harmless a party indemnified thereunder, the Company, the Selling Stockholders, and the Underwriters shall contribute to the aggregate losses, claims, damages, liabilities and expenses of the nature contemplated by such indemnification provision (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting in the case of losses, claims, damages, liabilities and expenses suffered by the Company, any Selling Stockholder or any Underwriter, any contribution received by the Company and any Selling Stockholder from persons, other than the Underwriters, who may also be liable for contribution, including persons who control the Company or any Selling Stockholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, officers of the Company who signed the Registration Statements and directors of the Company) as incurred to which the Company, any Selling Stockholder and one or more of the Underwriters may be subject, in such proportions as is appropriate to reflect the relative benefits received by the Company, the Selling Stockholders and the Underwriters from the Offering or, if such allocation is not permitted by applicable law, in such proportions as are appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company, the Selling Stockholders and the Underwriters in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company, the Selling Stockholders and the Underwriters in connection with the offering of the Shares shall be deemed to be the ratio that (x) (1) with respect to the Company, the net proceeds from the offering of the Shares (net of underwriting discounts and commissions but before deducting expenses) received by the Company, (2) with respect to each Selling Stockholder, the net proceeds from the offering of the Shares (net of underwriting discounts and commissions but before deducting expenses) received by such Selling Stockholder, and (3) with respect to each Underwriter, the total underwriting discounts and commissions received by such Underwriter, bears to (y) the aggregate public offering price of the Shares, in each case as set forth in the table on the cover page of the Prospectus Supplement. The relative fault of each of the Company, the Selling Stockholders and the Underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, a Selling Stockholder or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Stockholders and the Underwriters further agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such

purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 9. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 9 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any judicial, regulatory or other legal or governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 9, (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the discounts and commissions applicable to the Shares underwritten by it and distributed to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, (ii) no Selling Stockholder shall be required to contribute any amount in excess of the amount by which the proceeds (net of underwriting discounts and commissions but before deducting other expenses) applicable to the Shares sold by such Selling Stockholder pursuant to the transactions contemplated hereby exceeds the amount of any damages which such Selling Stockholder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (iii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 9, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each person, if any, who controls the Company, or a Selling Stockholder, within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each officer of the Company who shall have signed the Registration Statements and each director of the Company shall have the same rights to contribution as the Company, subject in each case to clauses (i), (ii) and (iii) of the immediately preceding sentence. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 9 or otherwise. The obligations of the Company and each Selling Stockholder, respectively, to contribute pursuant to this Section 9 are several in proportion to the respective number of Shares to be sold by the Company and each Selling Stockholder, respectively, and not joint. The obligations of the Underwriters to contribute pursuant to this Section 9 are several in proportion to the respective number of Shares to be purchased by each of the Underwriters hereunder and not joint.

10. Underwriter Default.

(a) If any Underwriter or Underwriters shall default in its or their obligation to purchase Firm Shares or Additional Shares hereunder, and if the Firm Shares or Additional Shares with respect to which such default relates (the “Default Shares”) do not (after giving effect to arrangements, if any, made by the Lead Managers pursuant to subsection (b) below) exceed in the aggregate 10% of the number of Firm Shares or Additional Shares, each non-defaulting Underwriter, acting severally and not jointly, agrees to purchase from the

Company or Selling Stockholders, as the case may be, that number of Default Shares that bears the same proportion of the total number of Default Shares then being purchased as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereto bears to the aggregate number of Firm Shares set forth opposite the names of the non-defaulting Underwriters, subject, however, to such adjustments to eliminate fractional shares as the Lead Managers in their sole discretion shall make.

(b) In the event that the aggregate number of Default Shares exceeds 10% of the number of Firm Shares or Additional Shares, as the case may be, the Lead Managers may in their discretion arrange for themselves or for another party or parties (including any non-defaulting Underwriter or Underwriters who so agree) to purchase the Default Shares on the terms contained herein. In the event that within five calendar days after such a default the Lead Managers do not arrange for the purchase of the Default Shares as provided in this Section 10, this Agreement or, in the case of a default with respect to the Additional Shares, the obligations of the Underwriters to purchase and of the Selling Stockholders to sell the Additional Shares shall thereupon terminate, without liability on the part of the Company or the Selling Stockholders with respect thereto or the Underwriters (except in each case as provided in Sections 6, 8, 9, 12 and 13), but nothing in this Agreement shall relieve a defaulting Underwriter or Underwriters of its or their liability, if any, to the other Underwriters and the Company for damages occasioned by its or their default hereunder.

(c) In the event that any Default Shares are to be purchased by the non-defaulting Underwriters, or are to be purchased by another party or parties as aforesaid, the Lead Managers or the Company shall have the right to postpone the Closing Date or Additional Closing Date, as the case may be for a period, not exceeding five business days, in order to effect whatever changes may thereby be made necessary in the Registration Statements or the Prospectus Supplement or in any other documents and arrangements, and the Company agrees to file promptly any amendment or supplement to the Registration Statements or the Prospectus Supplement which, in the opinion of Underwriters’ Counsel, may thereby be made necessary or advisable. The term “Underwriter” as used in this Agreement shall include any party substituted under this Section 10 with like effect as if it had originally been a party to this Agreement with respect to such Firm Shares and Additional Shares.

11. Selling Stockholder Default.

(a) If any Selling Stockholder or Selling Stockholders shall default in its or their obligation to sell and deliver any Shares hereunder, then the Lead Managers may, by notice to the Company, terminate this Agreement without any liability on the part of any non-defaulting party except that the provisions of Sections 1, 2, 6, 8, 9, 12 and 13 hereof shall remain in full force and effect. No action taken pursuant to this Section 11 shall relieve any Selling Shareholder so defaulting from liability, if any, in respect of such default.

In the event that such default occurs and the Company and Underwriters agree to proceed with the Offering, then the Underwriters may, at the option of the Lead Managers, or the Company shall have the right, in each case by notice to the other, to postpone the Closing Date or Additional Closing Date, as the case may be, for a period not exceeding five business days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or

the Prospectus Supplement or in any other documents and arrangements, and the Company agrees to file promptly any amendment or supplement to the Registration Statement or the Prospectus Supplement which, in the opinion of Underwriters’ Counsel, may thereby be made necessary or advisable; and in no event shall the Company be obligated to increase the number of Shares it is required to sell hereunder.

12. Survival of Representations and Agreements. All representations and warranties, covenants and agreements of the Underwriters, the Company and the Selling Stockholders contained in this Agreement or in certificates of officers of the Company or any subsidiary submitted pursuant hereto, including the agreements contained in Section 6, the indemnity agreements contained in Section 8 and the contribution agreements contained in Section 9, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person thereof or by or on behalf of the Company or any Selling Stockholder, any of their officers and directors or any controlling person thereof, and shall survive delivery of and payment for the Shares to and by the Underwriters. The representations contained in Sections 1 and 2, the agreements contained in Sections 6, 8, 9, 12 and 13, and the provisions of Sections 14 through 19, inclusive, hereof shall survive any termination of this Agreement, including termination pursuant to Section 10, 11 or 13 hereof.

13. Effective Date of Agreement; Termination.

(a) This Agreement shall become effective upon the execution of this Agreement.

(b) The Lead Managers shall have the right to terminate this Agreement at any time prior to the Closing Date or to terminate the obligations of the Underwriters to purchase the Additional Shares at any time prior to the Additional Closing Date, as the case may be, if (i) any domestic or international event or act or occurrence has materially disrupted, or in the opinion of the Lead Managers will in the immediate future materially disrupt, the market for the Company’s securities or securities in general; or (ii) if trading on The New York Stock Exchange (“the NYSE”) or The NASDAQ National Market (the “NASDAQ”) shall have been suspended or been made subject to material limitations, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the NYSE or the NASDAQ or by order of the Commission or any other governmental authority having jurisdiction; or (iii) if a banking moratorium has been declared by any state or federal authority or if any material disruption in commercial banking or securities settlement or clearance services shall have occurred; or (iv) (A) there shall have occurred any outbreak or escalation of hostilities or acts of terrorism involving the United States or there is a declaration of a national emergency or war by the United States or (B) if there shall have been any other calamity or crisis or any change in political, financial or economic conditions if the effect of any such event in (A) or (B), in the judgment of the Lead Managers, makes it impracticable or inadvisable to proceed with the offering, sale and delivery of the Firm Shares or the Additional Shares, as the case may be, on the terms and in the manner contemplated by the Prospectus.

(c) Any notice of termination pursuant to this Section 13 shall be in writing.

(d) If this Agreement shall be terminated pursuant to any of the provisions hereof (other than pursuant to notification by the Lead Managers as provided in Section 10(b) hereof), or if the sale of the Shares provided for herein is not consummated because any condition to the obligations of the Underwriters set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, the Company will, subject to demand by the Lead Managers, reimburse the Underwriters for all out-of-pocket expenses (including the fees and expenses of their counsel), incurred by the Underwriters in connection herewith.

17. The information in the Prospectus Supplement under the following captions (or, as applicable, certain portions of such information as indicated below), to the extent that such information constitutes matters of law or legal conclusions, or purports to describe certain provisions of specified documents, has been reviewed by us, and is correct in all material respects: “Risk Factors—Large payment obligations under our distribution agreement with General Motors may prevent us from becoming profitable or achieving profitability in a timely manner” and “Management—Shareholders and Noteholders Agreement.”

ANNEX II

Form of Opinion of ▇▇▇▇ ▇▇▇▇▇▇▇

1. Except as set forth in the Prospectus Supplement under the captions “Risk Factors —Failure to comply with FCC requirements could damage our business” and “Business—Regulatory Matters,” (i) the FCC has granted XM Radio all material authorizations needed to construct, launch, and operate a Satellite Digital Audio Radio Service system and offer a subscription service on a non-common carrier basis, and (ii) the FCC has assigned XM Radio two orbital locations at 85 degrees ▇.▇. and 115 degrees ▇.▇. for XM Radio’s two satellites and the frequency band 2332.5-2345 MHz to provide such Satellite Digital Audio Radio Service.

2. Except for such FCC consents, approvals, authorizations or orders that have already been obtained, no material consent, approval, authorization or order of the FCC is required to be obtained by the Company or XM Radio under the Communications Laws for the consummation of the transactions contemplated under the Underwriting Agreement, except that, from time to time, the Company or XM Radio may be required to obtain certain FCC authorizations that would be required in the ordinary course of business.

3. The execution and delivery of the Underwriting Agreement, and the consummation of the transactions contemplated thereunder, by the Company and XM Radio do not and will not violate any material provision of the Communications Laws.

4. The statements set forth in the Prospectus Supplement under the captions “Risk Factors —Failure to comply with FCC requirements could damage our business” and “Business—Regulatory Matters,” insofar as such statements constitute a summary of material (a) legal matters, (b) documents, or (c) proceedings under the Communications Laws, fairly present the information contained under such captions in light of the circumstances in which such statements are made.

5. Except as set forth in the Prospectus Supplement, to our knowledge, there is no investigation or complaint before the FCC pending or threatened in writing that is specifically directed against or in respect of the Company or XM Radio, or any of the FCC licenses held by XM Radio that would reasonably be expected to result in the revocation of any material FCC authorizations or otherwise to materially impair the operations of the Company or XM Radio taken as a whole.

ANNEX III

Form of Opinion of ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇ LLP

1. Each Selling Stockholder’s Board of Directors has adopted by requisite vote the resolutions necessary to authorize such Selling Stockholder’s execution and delivery of the Underwriting Agreement.

2. The execution and delivery by each Selling Stockholder of, and the performance by such Selling Stockholder of its obligations under, the Underwriting Agreement do not (i) result in any violation of the provisions of the Agreement of Limited Partnership of such Selling Stockholder and (ii) to our knowledge, result in any violation of any order, judgment or decree known to us of any court or governmental agency or body having jurisdiction over such Selling Stockholder.

3. To our knowledge, the Selling Stockholders were not required to obtain any consent, approval, authorization, or order of any court or governmental agency in order to obtain the right to enter into the Underwriting Agreement or to take any of the actions taken by the Selling Stockholders today to consummate the sale of the Initial Shares by each Selling Stockholder to be sold thereunder, except for registration under the Securities Act of 1933, as amended, of the Initial Shares and as may be required under other federal and state securities laws in connection with the purchase and distribution of the Initial Shares by the Underwriters with respect to which we express no opinion.

4. Upon your payment to the Selling Stockholders of the purchase price specified in the Underwriting Agreement and delivery to you, or such nominee as may be directed by you, of the certificate or certificates representing the Initial Shares upon consummation of the sale thereof in accordance with the Underwriting Agreement, you will have acquired ownership of the Initial Shares free of any adverse claim. For purposes of this opinion, we have assumed that you will have purchased the Initial Shares in good faith and without notice of any adverse claim or defect in the validity of the Initial Shares and that you will take possession at the closing of the certificates representing the Initial Shares and the instruments pursuant to which the Selling Stockholders have assigned the Initial Shares to you. We have also assumed that the Initial Shares are duly authorized and validly issued. The term “adverse claim” as used in this opinion has the meaning given such term in Section 8-105 of the Uniform Commercial Code and does not include (i) any claim which arises through you or any person claiming through you (such as any security interest you may have granted in the Initial Shares) and (ii) any adverse interest which would not be extinguished upon the purchase of the Initial Shares by a person who qualifies as a “bona fide purchaser” or “protected purchaser” under §8-303 of the Uniform Commercial Code. We advise you that we have no actual knowledge of the existence of any interest of the kind specified in clause (ii) of the preceding sentence.

Form of Opinion of General Counsel to ▇▇▇▇▇▇ Electronics Corporation

1. The Company is a corporation validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to own, lease and operate its properties and to carry on its business as now being conducted.

2. To my knowledge, except as disclosed in the Prospectus Supplement, the Company is the holder of record and has good and valid title to the certificates for the Shares to be sold by the Company free and clear of any security interest, claim, lien, limitation on voting rights or encumbrance.

3. Assuming that the Underwriters acquire the Shares being sold to it pursuant to the Agreement without notice of an adverse claim thereto, upon (a) the delivery to the Underwriters of such Shares, (b) the payment therefor in accordance with the terms of the Agreement and (c) the acquisition by the Underwriters of control of such Shares, the Underwriter will acquire such Shares free of any adverse claim. For purposes of this Paragraph 3, the terms “delivery”, “control”, “adverse claim” and “notice of an adverse claim” have the respective meanings ascribed thereto in Sections 8-301, 8-106, 8-102(a)(1) and 8-105 of the Uniform Commercial Code in effect in the State of New York (the “UCC”).

4. The Company has all requisite corporate power and authority to execute and deliver the Agreement and to perform its obligations thereunder. The execution, delivery and performance of the Agreement by the Company have been duly authorized by all necessary corporate action on the part of the Company. The Agreement has been duly and validly executed and delivered by the Company and (assuming the due authorization, execution and delivery thereof by the other parties thereto) constitutes the valid and binding obligation of the Company, enforceable against it in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution thereunder may be limited by federal or state securities laws or public policy relating thereto.

5. The execution and delivery by the Company of the Agreement and the performance by the Company of its obligations thereunder will not conflict with, constitute a default under or violate (i) any of the terms, conditions or provisions of the Certificate of Incorporation or by-laws of the Company, (ii) any of the terms, conditions or provisions of any material document, agreement or other instrument to which the Company is a party or by which it is bound of which I am aware, (iii) [New York], Delaware or federal law or regulation (other than federal and state securities or blue sky laws, as to which I express no opinion in this paragraph), or (iv) any judgment, writ, injunction, decree, order or ruling of any court or governmental authority binding on the Company of which I am aware.

6. No consent, approval, waiver, license or authorization or other action by or filing with any state or federal governmental authority is required in connection with the execution and delivery by the Company of the Agreement, the consummation by the Company of the transactions contemplated thereby or the performance by the Company of its obligations thereunder, except for filings and other actions required pursuant to the Securities Act of 1933 and/or the Securities Exchange Act of 1934 and the rules and regulations thereunder, federal and state securities or blue sky laws, as to which I express no opinion.

Dear Sirs and Mesdames:

The undersigned understands that Bear, ▇▇▇▇▇▇▇ & Co. Inc. (“Bear ▇▇▇▇▇▇▇”), and the Underwriters listed on Schedule I of the Underwriting Agreement (together, the “Underwriters”), will enter into an Underwriting Agreement with XM Satellite Radio Holdings Inc., a Delaware corporation (the “Company”), providing for a public offering (the “Public Offering”) of the Company’s Class A common stock, par value $.01 per share (the “Common Stock”) pursuant to Registration Statements on Form S-3 (File No. 333-89132, No. 333-102966 and No. 333-106824).

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of Bear ▇▇▇▇▇▇▇ on behalf of the Underwriters, it will not, and will not permit its subsidiaries to, during the period commencing on the date hereof and ending 90 days after the date of the final prospectus relating to the Public Offering (the “Lock-Up Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, establish or increase an open “put equivalent position” or liquidate or decrease a “call equivalent position” with respect to shares of Common Stock within the meaning of Section 16 of the Securities and Exchange Act of 1934, as amended, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) the sale of any shares of Common Stock to the Underwriters pursuant to the Underwriting Agreement or (b) transactions relating to shares of

Nothing herein shall prohibit any conversion of the Company’s Series A convertible preferred stock, Series B convertible redeemable preferred stock, Series C convertible redeemable preferred stock or Class B common stock into Common Stock.

The undersigned hereby authorizes the Company during the Lock-Up Period to cause any transfer agent for the Common Stock to decline to transfer, and to note stop transfer restrictions on the stock register and other records relating to, Common Stock for which the undersigned is the record holder and, in the case of Common Stock for which the undersigned is the beneficial but not the record holder, agrees during the Lock-Up Period to cause the record holder to cause the relevant transfer agent to decline to transfer, and to note stop transfer restrictions on the stock register and other records relating to, such Common Stock. The undersigned hereby further agrees that, without the prior written consent of Bear ▇▇▇▇▇▇▇, during the Lock-up Period the undersigned will not, nor will it permit any of its subsidiaries to (x) file or participate in the filing with the Securities and Exchange Commission of any registration statement, or circulate or participate in the circulation of any preliminary or final prospectus or other disclosure document with respect to any proposed offering or sale of Common Stock and (y) exercise any rights the undersigned or a subsidiary may have to require registration with the Securities and Exchange Commission of any proposed offering or sale of Common Stock, other than “piggy-back” registration rights on future issuances of Common Stock by the Company.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Agreement and that this Agreement constitutes the legal, valid and binding obligation of the undersigned, enforceable in accordance with its terms. Upon request, the undersigned will execute any additional documents necessary in connection with enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, legal representatives, successors and assigns of the undersigned from the date first above written.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.
