In addition, the requesting Holder shall provide any additional certifications, documents and information, as applicable, required pursuant to the following provisions of this Section 2.06(e).

(h) CANCELLATION AND/OR ADJUSTMENT OF GLOBAL NOTES. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. 38 <Page> (i) GENERAL PROVISIONS RELATING TO TRANSFERS AND EXCHANGES. (i) To permit registrations of transfers and exchanges, the Company shall, subject to the other provisions of this Section 2.06, execute and the Trustee shall authenticate Global Notes and Definitive Notes upon the Company's order or at the Registrar's request in accordance with the provisions of Section 2.02 hereof. (ii) No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 5.14 and 10.05 hereof). (iii) The Registrar shall not be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. (iv) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. (v) The Company shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 Business Days before the day of the mailing of a notice of redemption or repurchase under Section 3.03 or 5.14 hereof, as applicable, and ending at the close of business on such day, (B) to register the transfer of or to exchange any Note so selected for redemption or repurchase in whole or in part, except the unredeemed portion of any Note being redeemed or repurchased in part or (C) to register the transfer of or to exchange a Note between a Record Date and the next succeeding Interest Payment Date. (vi) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary. (vii) The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof. (viii) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile. Section 2.07. REPLACEMENT NOTES. 39 <Page> If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee's requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the reasonable judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto, and may charge for its expenses (including the fees and expenses of the Trustee and reasonable attorneys' fees and expenses) in replacing a Note. Every replacement Note is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. If any mutilated, lost, stolen or destroyed Note has become or is about to become due and payable, the Company, in its sole discretion, may, instead of issuing a new Note, pay such Note. Section 2.08. OUTSTANDING NOTES. The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. A Note, or portion thereof, does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee received proof satisfactory to it that the replaced Note is held by a bona fide purchaser or protected purchaser. If the principal amount of any Note is considered paid under Section 5.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereto) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest. Section 2.09. TREASURY NOTES. In determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Subsidiary or Affiliate of the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned shall be so disregarded. 40 <Page> Section 2.10. TEMPORARY NOTES. Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. Holders of temporary Notes shall be entitled to all of the benefits of this Indenture. Section 2.11. CANCELLATION. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy canceled Notes (subject to the record retention requirements of the Exchange Act). Certification of the destruction of all canceled Notes shall be delivered to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. Section 2.12. DEFAULTED INTEREST. If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent Special Record Date, in each case at the rate provided in the Notes and in Section 5.01 hereof. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such Special Record Date and payment date; PROVIDED that no such Special Record Date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the Special Record Date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the Special Record Date, the related payment date and the amount of such interest to be paid. The defaulted interest shall be considered paid upon deposit with the Trustee or the Paying Agent of an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest, and interest on such defaulted interest shall thereafter cease to accrue from that date. The Company may make payment of any defaulted interest in any other lawful manner not inconsistent with the requirements of any securities exchange or other trading market on which the securities of the Company are listed or traded, and upon such notice as may be required by such exchange or trading market, if, after written notice given by the Company to the Trustee of the proposed payment, such manner of payment shall be deemed practicable by the Trustee. Section 2.13. CUSIP NUMBERS. 41 <Page> The Company in issuing the Notes shall use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of redemption as a convenience to Holders; PROVIDED that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or the omission of such numbers. The Company will promptly notify the Trustee of any change in the CUSIP numbers. ARTICLE 3. REDEMPTION AND PREPAYMENT SECTION 3.01 NOTICES TO TRUSTEE. If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee, at least 45 days but not more than 60 days before a redemption date, an Officers' Certificate setting forth (i) the clause of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed, (iv) the redemption price, and (v) the CUSIP numbers of the Notes to be redeemed. SECTION 3.02 SELECTION OF NOTES TO BE REDEEMED If less than all of the Notes are to be redeemed at any time, the Trustee shall select the Notes to be redeemed or purchased among the Holders of the Notes in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis or by lot or such other reasonable method as determined by the Trustee. In the event of a partial redemption by lot, the particular Note to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption. The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of $1,000 or whole multiples of $1,000; PROVIDED, HOWEVER, that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 42 <Page> SECTION 3.03 NOTICE OF REDEMPTION Subject to the provisions of Section 3.09 hereof, at least 45 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at such Holder's registered address. The notice shall identify the Notes to be redeemed and shall state: (a) the redemption date; (b) the redemption price; (c) the CUSIP numbers of the Notes; (d) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note; (e) the name and address of the Paying Agent; (f) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; (g) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date; (h) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and (i) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. At the Company's written request, the Trustee shall give the notice of redemption in the Company's name and at its expense; PROVIDED, HOWEVER, that the Company shall have delivered to the Trustee, at least 50 days prior to the redemption date, an Officers' Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. SECTION 3.04 EFFECT OF NOTICE OF REDEMPTION Once notice of redemption is mailed in accordance with Section 3.03 hereof, any Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional. SECTION 3.05 DEPOSIT OF REDEMPTION PRICE 43 <Page> Prior to 11:00 a.m., New York City time on the redemption date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed. If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after a Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such Record Date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 5.01 hereof. SECTION 3.06 NOTES REDEEMED IN PART Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon the Company's written request, the Trustee shall authenticate, for the Holder at the expense of the Company, a new Note equal in principal amount to the unredeemed portion of the Note surrendered. SECTION 3.07 OPTIONAL REDEMPTION (a) The Notes shall not be redeemable at the Company's option prior to September 15, 2006. Thereafter, the Notes shall be subject to redemption at any time at the option of the Company, in whole or in part, upon not less than 45 nor more than 60 days' notice, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest thereon to the applicable redemption date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date), if redeemed during the twelve-month period beginning on September 15 (September 17 for the year 2007) of the years indicated below: <Table> <Caption> PERCENTAGE OF YEAR PRINCIPAL AMOUNT ---- ---------------- 2006.......................................................... 104.250% 2007.......................................................... 103.190% 2008.......................................................... 102.130% 2009.......................................................... 101.060% 2010 and thereafter........................................... 100.000% </Table> 44 <Page> (b) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof. SECTION 3.08 APPLICATION OF EXCESS PROCEEDS OR ALLOCATED CAPACITY PROCEEDS. In the event that, pursuant to Section 5.09 or Section 5.24 hereof, the Company shall be required to commence an Asset Sale Offer or an Offer to Purchase, respectively, it shall follow the procedures specified below. The Asset Sale Offer or Offer to Purchase, as the case may be, shall remain open for a period of 20 Business Days following its commencement and no longer, except to the extent that a longer period is required by applicable law (the "OFFER PERIOD"). No later than five Business Days after the termination of the Offer Period (the "PURCHASE DATE"), the Company shall purchase the principal amount of Notes required to be purchased pursuant to Section 5.09 or Section 5.24 hereof (the "OFFER AMOUNT") or, if less than the Offer Amount has been tendered, all Notes tendered in response to the Asset Sale Offer or Offer to Purchase, as applicable. Payment for any Notes so purchased shall be made in the same manner as interest payments are made. If the Purchase Date is on or after a Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest shall be paid to the Person in whose name a Note is registered at the close of business on such Record Date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Asset Sale Offer or Offer to Purchase, as applicable. Upon the commencement of an Asset Sale Offer or Offer to Purchase, as applicable, the Company shall send, by first class mail, a notice to the Trustee and each of the Holders. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer or Offer to Purchase, as applicable. The Asset Sale Offer or Offer to Purchase, as applicable, shall be made to all Holders. The notice, which shall govern the terms of the Asset Sale Offer or Offer to Purchase, as applicable, shall state: (a) that the Asset Sale Offer or Offer to Purchase, as applicable, is being made pursuant to this Section 3.08 and Section 5.09 or 5.24, as the case may be, hereof and the length of time the Asset Sale Offer or Offer to Purchase, as applicable, shall remain open; (b) the Offer Amount, the purchase price and the Purchase Date; (c) that any Note not tendered or accepted for payment shall continue to accrue interest; (d) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer or Offer to Purchase, as applicable, shall cease to accrue interest after the Purchase Date; 45 <Page> (e) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer or Offer to Purchase, as applicable, may only elect to have all of such Note purchased and may not elect to have only a portion of such Note purchased; (f) that Holders electing to have a Note purchased pursuant to any Asset Sale Offer or Offer to Purchase, as applicable, shall be required to surrender the Note, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Note completed, or transfer by book-entry transfer, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three Business Days before the Purchase Date; (g) that Holders shall be entitled to withdraw their election if the Company, the depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a facsimile transmission or letter setting forth the name of the Holder, the aggregate principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; (h) that, if the aggregate principal amount of Notes surrendered by Holders exceeds the Offer Amount, the Company shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $1,000, or integral multiples thereof, shall be purchased); and (i) that Holders whose Notes were purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). On or before 10:00 a.m. New York City time on the Purchase Date, the Company shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount or portions thereof tendered pursuant to the Asset Sale Offer, or Offer to Purchase, as applicable, or if less than the Offer Amount has been tendered, all Notes tendered, and shall deliver to the Trustee an Officers' Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.08. The Company, the Depositary or the Paying Agent, as the case may be, shall promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company shall promptly issue a new Note, and the Trustee, upon written request from the Company, shall authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Asset Sale Offer or Offer to Purchase, as applicable, on the Purchase Date. Other than as specifically provided in this Section 3.08, any purchase pursuant to this Section 3.08 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof. 46 <Page> SECTION 3.09 MANDATORY REDEMPTION Except as set forth in this Section 3.09, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes. If (A) the Requisite Company Vote has not been received by the date that is six months after the date hereof or (B) for any reason the C&MA Assignment is deemed to be an invalid or ineffective assignment under the terms of the C&MA, each Holder of the Notes will have the right to require the Company to purchase all of such Holder's Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest thereon to the date of purchase (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date). Any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof. ARTICLE 4. CONVERSION Section 4.01. CONVERSION PRIVILEGE Subject to the further provisions of this Section 4.01, from and after the time that the Requisite Company Vote is obtained, a Holder of a Note may convert such Note at the Conversion Price (as hereinafter defined) then in effect into Class A Common Stock (i) at any time after the Regulatory Relief Date, if at such time such Holder is a Regulated Person, or (ii) at any time, if such Holder is not a Regulated Person; PROVIDED, HOWEVER, that the Initial Purchaser or any of its Affiliates or any Holder that acquires Notes pursuant to any Transfer other than pursuant to a Public Resale may not convert such Note if, after giving effect to such conversion, such Holder would be deemed to be an "affiliate" as that term is defined in, and for the purposes of, either of the Franchise Agreements; and PROVIDED, FURTHER, that, if such Note is called for redemption pursuant to Article 3, such conversion right shall terminate at the close of business on the Business Day immediately preceding the redemption date for such Note (unless the Company shall default in making the redemption payment when due, in which case the conversion right shall terminate at the close of business on the date such default is cured and such Note is redeemed); and PROVIDED, FURTHER, that, if the Holder of a Note tenders such Note pursuant to a Change of Control Offer, such Note may only be converted if such Holder properly withdraws its election to participate in the Change of Control Offer prior to consummation of the Change of Control Offer. The number of shares of Class A Common Stock issuable upon conversion of a Note shall be determined by dividing the principal amount of the Note or portion thereof surrendered for conversion by the Conversion Price in effect on the Conversion Date. The initial conversion price is $0.53875 and is subject to adjustment or voluntary reduction as provided in this Article 4 (the "CONVERSION PRICE"). A Holder may convert a portion of a Note equal to $1,000 or any integral multiple thereof. Provisions of this Agreement that apply to conversion of all of a Note also apply to conversion of a portion of a Note. 47 <Page> A Holder of Notes is not entitled to any rights of a holder of Class A Common Stock until such Holder has converted its Notes to Class A Common Stock, and only to the extent such Notes are deemed to have been converted into Class A Common Stock pursuant to this Article 4. Section 4.02. CONVERSION PROCEDURE To convert a Note, a Holder must (a) complete and manually sign the conversion notice on the back of the Note and deliver such notice to the Conversion Agent; (b) surrender the Note to the Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by the Registrar or the Conversion Agent, and (d) pay any transfer or similar tax, if required pursuant to Section 4.04 hereof. The date on which the Holder satisfies all of those requirements is the "CONVERSION DATE." As soon as practicable after the Conversion Date, the Company shall deliver to the Holder through the Conversion Agent a certificate for the number of whole shares of Class A Common Stock issuable upon the conversion, payment for accrued interest on such Note to the extent required by this Section 4.02 and cash in lieu of any fractional shares pursuant to Section 4.03. The Company may, at any time and as a condition to delivering such shares of Class A Common Stock, require any Holder to deliver a representation and warranty made to the Company and an officer's certificate certifying as to whether or not such Holder is a Regulated Person as of the Conversion Date and certifying the number of issued and outstanding shares of Common Stock "Beneficially Owned" (as defined in Rule 13d-3 under the Exchange Act) by such Holder as of the Conversion Date. The Company may also rely upon the stock ledger and corporate records of the Company. The Trustee shall have no obligation to make any such determination. The person in whose name the certificate is registered shall be deemed to be a shareholder of record on the Conversion Date; PROVIDED, HOWEVER, that no surrender of a Note on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the person or persons entitled to receive the shares of Class A Common Stock upon such conversion as the record holder or holders of such shares of Class A Common Stock on such date, but such surrender shall be effective to constitute the person or persons entitled to receive such shares of Class A Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; and PROVIDED, FURTHER, that such conversion shall be at the Conversion Price in effect on the Conversion Date as if the stock transfer books of the Company had not been closed. Upon conversion of a Note, such person shall no longer be a Holder of such Note. If any Holder surrenders a Note for conversion after the close of business on the Record Date for the payment of an installment of interest and before the close of business on the related Interest Payment Date, the Company shall pay accrued interest through the Conversion Date to the Holder of such Note on such Record Date. If a Holder converts more than one Note at the same time, the number of shares of Class A Common Stock issuable upon the conversion shall be based on the aggregate principal amount of Notes converted. 48 <Page> Upon surrender of a Note that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new Note equal in principal amount to the unconverted portion of the Note surrendered. Section 4.03. FRACTIONAL SHARES The Company will not issue fractional shares of Class A Common Stock upon conversion of Notes. In lieu thereof, the Company will pay an amount in cash based upon the Closing Price of the Class A Common Stock on the Trading Day immediately prior to the Conversion Date. Section 4.04. TAXES ON CONVERSION If a Holder converts a Note, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of Class A Common Stock upon such conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder's name. The Conversion Agent may refuse to deliver the certificate representing the Class A Common Stock being issued in a name other than the Holder's name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holder's name. Nothing herein shall preclude any tax withholding required by law or regulation. Section 4.05. COMPANY TO PROVIDE STOCK The Company shall, prior to issuance of any Notes hereunder, and from time to time as it may be necessary, reserve, out of its authorized but unissued Class A Common Stock, a sufficient number of shares of Class A Common Stock to permit the conversion of all outstanding Notes into shares of Class A Common Stock. All shares of Class A Common Stock delivered upon conversion of the Notes shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive rights and free of any Lien or adverse claim. The Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Class A Common Stock upon conversion of Notes, if any, and will list or cause to have quoted such shares of Class A Common Stock on each national securities exchange or in the over-the-counter market or such other market on which the Class A Common Stock is then listed or quoted. Section 4.06. ADJUSTMENT OF CONVERSION PRICE. The Conversion Price shall be adjusted from time to time by the Company as follows: (a) In case the Company shall (i) pay a dividend in shares of Class A Common Stock to the holders of the Class A Common Stock, (ii) make a distribution in shares of Class A Common Stock to the holders of the Class A Common Stock, (iii) 49 <Page> subdivide or split its outstanding Class A Common Stock into a larger number of shares, or (iv) combine its outstanding Class A Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior thereto shall be adjusted so that the Holder of any Note thereafter surrendered for conversion shall be entitled to receive that number of shares of Class A Common Stock which it would have owned or been entitled to receive had such Note been converted immediately prior to the happening of such event. An adjustment made pursuant to this subsection (a) shall become effective as of the close of business on the record date in the case of a dividend in shares or distribution and shall become effective as of the close of business on the effective date in the case of a subdivision, split or combination. (b) In case (i) the Company shall issue rights or warrants to all or substantially all holders of its Class A Common Stock entitling them (for a period commencing no earlier than the record date described below and expiring not more than 60 days after such record date) to subscribe for or purchase shares of Class A Common Stock (or securities convertible into Class A Common Stock) at a price per share less than the Current Market Price per share of Class A Common Stock (as determined in accordance with subsection (g) of this Section 4.06) at the record date for the determination of shareholders entitled to receive such rights or warrants or (ii) the Company shall sell or issue any Class A Common Stock and the consideration per share of Class A Common Stock to be paid upon such issuance or subscription is more than 5% less than the Current Market Price per share of Class A Common Stock or the Company shall sell or issue warrants, rights or other convertible securities to subscribe for or purchase shares of Class A Common Stock at a price per share more than 5% less than the Current Market Price per share of Class A Common Stock (each as determined in accordance with subsection (g) of this Section 4.06) on the date of such sale or issuance, the Conversion Price in effect as of the close of business on the record date thereto shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect on the record date by a fraction of which the numerator shall be the number of shares of Class A Common Stock outstanding on such record date, plus the number of shares which the aggregate offering price of the total number of shares of Class A Common Stock so offered (or the aggregate conversion price of the convertible securities so offered) would purchase at such Current Market Price, and of which the denominator shall be the number of shares of Class A Common Stock outstanding on such record date plus the number of additional shares of Class A Common Stock offered (or into which the convertible securities so offered are convertible). Such adjustment shall be made successively whenever any such rights, warrants or convertible securities are issued, and shall become effective as of the close of business on such record date. If at the end of the period during which such rights or warrants are exercisable not all rights or warrants shall have been exercised, the adjusted Conversion Price shall be immediately readjusted to what it would have been based upon the number of additional shares of Class A Common Stock actually issued (or the number of shares of Class A Common Stock issuable upon conversion of convertible securities actually issued). (c) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock, cash (excluding (x) any regular cash dividend on the Common Stock to the extent that the aggregate cash dividend per share of Common 50 <Page> Stock in any four fiscal quarters does not exceed the greater of (A) the amount per share of Common Stock of the cash dividend on the Common Stock for the preceding four fiscal quarters to the extent that such dividend for the preceding four fiscal quarters did not require any adjustment of the Conversion Price pursuant to this Section 4.06(c) (as adjusted to reflect subdivisions or combinations of the Common Stock), and (B) 3.75% of the arithmetic average of the Closing Prices (as set forth in Section 4.06(g)) during the ten Trading Days immediately prior to the date of declaration of such dividend, (y) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary, and (z) any cash that is distributed as part of a distribution requiring a Conversion Price adjustment pursuant to Section 4.06(e)), then, in such case, the Conversion Price shall be decreased so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the record date of such action by a fraction of which the numerator shall be the Current Market Price of the Class A Common Stock on such record date less the amount of cash so distributed (and not excluded as provided above) applicable to one share of Common Stock and the denominator shall be the Current Market Price of the Class A Common Stock on such record date, such decrease shall be effective immediately prior to the opening of business on the day following the record date of such action; PROVIDED, HOWEVER, that in the event the portion of cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Class A Common Stock on such record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion the amount of cash such Holder would have received had such Holder converted each Note on the record date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. If any adjustment is required to be made as set forth in this Section 4.06(c) as a result of a distribution that is a regular dividend, such adjustment shall be based upon the amount by which such distribution exceeds the amount of the regular cash dividend permitted to be excluded pursuant hereto. If an adjustment is required to be made as set forth in this Section 4.06(c) above as a result of a distribution that is not a regular dividend, such adjustment shall be based upon the full amount of the distribution. (d) In case a tender or exchange offer made by the Company or any Subsidiary of the Company for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of Common Stock having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) that, as of the last time (the "EXPIRATION TIME") tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), exceeds the Current Market Price of the Class A Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Price shall be decreased so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the Expiration Time by a fraction of which the numerator shall be the product of the number of Class A Common Stock outstanding (including any tendered or exchanged shares) on the Expiration Time multiplied by the Current Market Price of the Class A Common Stock on the Trading Day next succeeding the Expiration Time, less the fair market value (determined as 51 <Page> aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "PURCHASED SHARES") and the denominator shall be the product of the number of Class A Common Stock outstanding (less any Purchased Shares) on the Expiration Time and the Current Market Price of the Class A Common Stock on the Trading Day next succeeding the Expiration Time, such reduction to become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender or exchange offer has not been made. (e) In case the Company shall distribute to all or substantially all holders of its Class A Common Stock any shares of capital stock of the Company (other than Class A Common Stock), evidences of indebtedness or other non-cash assets (including securities of any Person), or shall distribute to all holders of its Class A Common Stock rights or warrants to subscribe for or purchase any of its securities (excluding those referred to in subsection (b) of this Section 4.06), then in each such case the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect as of the close of business on the record date for such distribution by a fraction of which the numerator shall be the Current Market Price of the Class A Common Stock on the record date mentioned below less the fair market value on such record date (as reasonably determined by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and set forth in a Board Resolution delivered to the Trustee in an Officers' Certificate) of the portion of the capital stock, evidences of indebtedness or other assets so distributed or of such rights or warrants applicable to one share of Class A Common Stock (determined on the basis of the number of shares of Class A Common Stock outstanding on the record date), and of which the denominator shall be the Current Market Price per share (as determined in accordance with subsection (g) of this Section 4.06) of the Class A Common Stock on such record date. Such adjustment shall become effective as of the close of business on the record date for the determination of shareholders entitled to receive such distribution. Notwithstanding the foregoing, in the event that the Company shall distribute rights or warrants (other than those referred to in subsection (b) of this Section 4.06) ("RIGHTS") pro rata to holders of Class A Common Stock, the Company may, in lieu of making any adjustment pursuant to this Section 4.06, make proper provision so that each holder of a Note who converts such Note (or any portion thereof) after the record date for such distribution and prior to the expiration or redemption of the Rights shall be entitled to receive upon such conversion, in addition to the shares of Class A Common Stock issuable upon such conversion (the "CONVERSION SHARES"), a number of Rights to be determined as follows: (i) if such conversion occurs on or prior to the date for the distribution to the holders of Rights of separate certificates evidencing such Rights (the "DISTRIBUTION DATE"), the same number of Rights to which a holder of a number of shares of Class A Common Stock equal to the number of Conversion Shares is entitled at the time of such conversion in accordance with the terms and provisions of and applicable to 52 <Page> the Rights and (ii) if such conversion occurs after the Distribution Date, the same number of Rights to which a holder of the number of shares of Class A Common Stock into which the principal amount of the Note so converted was convertible as of the close of business on the Distribution Date would have been entitled on the Distribution Date in accordance with the terms and provisions of and applicable to the Rights. (f) In case of a tender or exchange offer made by a Person other than the Company or any Subsidiary of the Company for an amount which increases the offeror's ownership of Class A Common Stock to more than 35% of the Class A Common Stock outstanding and shall involve the payment by such Person of consideration per share of Class A Common Stock having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a Board Resolution) at the last time (the "TENDER EXPIRATION TIME") tenders or exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended) that exceeds the Current Market Price per share of the Class A Common Stock on the Trading Day next succeeding the Tender Expiration Time, and in which, as of the Tender Expiration Time, the Board of Directors is not recommending rejection of the offer, the Conversion Price shall be decreased so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the Tender Expiration Time by a fraction of which the numerator shall be the number of shares of Class A Common Stock outstanding (including any tendered or exchanged shares) at the Tender Expiration Time multiplied by the Current Market Price of the Class A Common Stock on the Trading Day next succeeding the Tender Expiration Time and the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Tender Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "ACCEPTED PURCHASED SHARES") and (y) the product of the number of shares of Class A Common Stock outstanding (less any Accepted Purchased Shares) at the Tender Expiration Time and the Current Market Price of the Class A Common Stock on the Trading Day next succeeding the Tender Expiration Time, such decrease to become effective immediately prior to the opening of business on the day following the Tender Expiration Time. In the event that such Person is obligated to purchase shares pursuant to any such tender or exchange offer, but such Person is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender or exchange offer had not been made. Notwithstanding the foregoing, the adjustment described in this Section 4.06(f) shall not be made if: (a) as of the Tender Expiration Time, the offering documents with respect to such offer disclose a plan or intention to cause the Company to engage in any transaction described in Article 6; or (b) the Initial Purchaser or any of its Affiliates do not beneficially own all of the Notes. (g) For purposes of this Section 4.06, the following terms shall have the meaning indicated: (i) "CLOSING PRICE" with respect to any securities on any date shall mean the closing sale price, regular way, on such day or, in case no such sale takes 53 <Page> place on such day, the average of the reported closing bid and asked prices, regular way, in each case on the New York Stock Exchange, or, if such security is not listed or admitted to trading on such Exchange, on the principal security exchange or quotation system in the United States on which such security is quoted or listed or admitted to trading, or, the average of the closing bid and asked prices of such security on the over-the-counter market on the day in question as reported by the Nasdaq National Market or a similar generally accepted reporting service, or if not so available, in such manner as furnished by any New York Stock Exchange member firm selected from time to time by the Board of Directors for that purpose, or a price determined in good faith by the Board of Directors or, to the extent permitted by applicable law, a duly authorized committee thereof, whose determination shall be conclusive. (ii) "CURRENT MARKET PRICE" shall mean the average of the daily Closing Prices per share of Class A Common Stock for the ten consecutive Trading Days immediately prior to the date in question; PROVIDED, HOWEVER, that (A) if the "ex" date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to this Section 4.06 occurs during such ten consecutive Trading Days, the Closing Price for each Trading Day prior to the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the fraction by which the Conversion Price is so required to be adjusted as a result of such other event, and (B) if the "ex" date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 4.06(a), (b), (c), (d) or (e) occurs on or after the "ex" date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event, and (C) if the "ex" date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (A) or (B) of this proviso, the Closing Price for each Trading Day on or after such "ex" date shall be adjusted by adding thereto the amount of any cash and the Fair Market Value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 4.06(d), (e) or (f), whose determination shall be conclusive and described in a resolution of the Board of Directors) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Class A Common Stock as of the close of business on the day before such "ex" date. For purposes of any computation under Section 4.06(f), the Current Market Price of the Class A Common Stock on any date shall be deemed to be the average of the daily Closing Prices per share of Class A Common Stock for such day and the next two succeeding Trading Days; PROVIDED, HOWEVER, that if the "ex" date for any event (other than the tender or exchange offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 4.06(a), (b), (c), (d), (e) or (f) (occurs on or after the Expiration Time or Tender Expiration Time, as the case may be, for the tender or exchange offer requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term "EX" DATE, (1) when used with respect to any 54 <Page> issuance or distribution, means the first date on which the Class A Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution, (2) when used with respect to any subdivision or combination of shares of Class A Common Stock, means the first date on which the Class A Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and (3) when used with respect to any tender or exchange offer, means the first date on which the Class A Common Stock trades regular way on such exchange or in such market after the Expiration Time or Tender Expiration Time, as the case may be, of such offer. (iii) "FAIR MARKET VALUE" shall mean the amount which a willing buyer would pay a willing seller in an arm's length transaction. (h) In any case in which this Section 4.06 shall require that an adjustment be made on a record date established for purposes of this Section 4.06, the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the certificate described in Section 4.09) issuing to the Holder of any Note converted after such record date but prior to the issue date, the shares of Class A Common Stock and other capital stock of the Company issuable upon such conversion over and above the shares of Class A Common Stock and other capital stock of the Company issuable upon such conversion only on the basis of the Conversion Price prior to adjustment; and, in lieu of the shares the issuance of which is so deferred, the Company shall issue or cause its transfer agents to issue due bills or other appropriate evidence prepared by the Company of the right to receive such shares. If any distribution in respect of which an adjustment to the Conversion Price is required to be made as of the record date or effective date therefor is not thereafter made or paid by the Company for any reason, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect if such record date had not been fixed or such effective date had not occurred. Section 4.07. NO ADJUSTMENT No adjustment in the Conversion Price shall be required unless the adjustment would require an increase or decrease of at least 1% in the Conversion Price as last adjusted; PROVIDED, HOWEVER, that any adjustments which by reason of this Section 4.07 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 4 shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. No adjustment need be made for a transaction referred to in Section 4.06 if all Holders are entitled to participate in the transaction on a basis and with notice to the same extent as holders of Class A Common Stock participate in the transaction. The Company shall give notice to the Trustee of any such determination. No adjustment need be made for rights to purchase Class A Common Stock or issuances of Class A Common Stock pursuant to a Company plan for reinvestment of dividends or interest. 55 <Page> No adjustment need be made for a change in the par value or a change to no par value of the Class A Common Stock. To the extent that the Notes become convertible into the right to receive cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash. Section 4.08. ADJUSTMENT FOR TAX PURPOSES The Company shall be entitled to make such reductions in the Conversion Price, in addition to those required by Section 4.06, as it in its discretion shall determine to be advisable in order that any stock dividends, subdivisions of shares, distributions of rights to purchase stock or Notes or distributions of Notes convertible into or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable, PROVIDED that such reduction does not have an adverse effect for tax purposes, or otherwise, on holders of the Notes. Section 4.09. NOTICE OF ADJUSTMENT Whenever the Conversion Price is adjusted, the Company shall promptly mail to Holders a notice of the adjustment and file with the Trustee an Officers' Certificate briefly stating the facts requiring the adjustment, the manner of computing it and the new Conversion Price. Section 4.10. NOTICE OF CERTAIN TRANSACTIONS. In the event that: (a) the Company takes any action which would require an adjustment in the Conversion Price; (b) the Company consolidates or merges with, or transfers all or substantially all of its property and assets to, another corporation and shareholders of the Company must approve the transaction; or (c) there is a dissolution or liquidation of the Company, the Company shall mail to Holders and file with the Trustee a notice stating the proposed record or effective date, as the case may be. The Company shall mail the notice before such date to the same extent as such notice is mailed to the stockholders of the Company. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in clause (a), (b) or (c) of this Section 4.10. 56 <Page> Section 4.11. EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE, TRANSFER OR CONVEYANCE ON CONVERSION PRIVILEGE If any of the following shall occur, namely: (a) any reclassification or change of shares of Class A Common Stock issuable upon conversion of the Notes (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination, or any other change for which an adjustment is provided in Section 4.06); (b) any consolidation or merger to which the Company is a party other than a merger in which the Company is the continuing corporation and which does not result in any reclassification of, or change (other than a change in name, or in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) in, outstanding shares of Class A Common Stock; or (c) any sale, transfer or conveyance of all or substantially all of the property and assets of the Company to any Person, then the Company, or such successor or purchasing corporation, as the case may be, shall, as a condition precedent to such reclassification, change, consolidation, merger, sale, transfer or conveyance, execute and deliver to the Trustee an amendment to this Indenture providing that the Holder of each Note then outstanding shall have the right to convert such Note into the kind and amount of shares of stock and other Notes and property (including cash) receivable upon such reclassification, change, consolidation, merger, sale, transfer or conveyance by a holder of the number of shares of Class A Common Stock deliverable upon conversion of such Note immediately prior to such reclassification, change, consolidation, merger, sale, transfer or conveyance. Such amendment to this Indenture shall provide for adjustments of the Conversion Price which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Price provided for in this Article 4. If, in the case of any such consolidation, merger, sale, transfer or conveyance, the stock or other Notes and property (including cash) receivable thereupon by a holder of Class A Common Stock include shares of stock or other securities and property of a corporation other than the successor or purchasing corporation, as the case may be, in such consolidation, merger, sale, transfer or conveyance, then such amendment to this Indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The provisions of this Section 4.11 shall similarly apply to successive consolidations, mergers, sales, transfer or conveyances. In the event the Company shall execute an amendment to this Agreement pursuant to this Section 4.11, the Company shall promptly file with the Trustee (x) an Officers' Certificate briefly stating the reasons therefor, the kind or amount of shares of stock or other Notes or property (including cash) receivable by Holders of the Notes upon the conversion of their Notes after any such reclassification, change, consolidation, merger, sale, transfer or conveyance, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and (y) an Opinion of Counsel that all conditions precedent have been complied with. Section 4.12. TRUSTEE'S DISCLAIMER. The Trustee shall have no duty to determine when an adjustment under this Article 4 should be made, how it should be made or what such adjustment should be, 57 <Page> but may accept as conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected in relying upon, an Officers' Certificate including the Officers' Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.09. The Trustee makes no representation as to the validity or value of any Notes or assets issued upon conversion of Notes, and the Trustee shall not be responsible for the Company's failure to comply with any provisions of this Article 4. The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 4.11, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officers' Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.11. Section 4.13. VOLUNTARY REDUCTION. The Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least 20 days or such longer period as may be required by law and if the reduction is irrevocable during the period; PROVIDED, HOWEVER, that in no event may the Conversion Price be less than the par value of a share of Class A Common Stock. ARTICLE 5. COVENANTS Section 5.01. PAYMENT OF NOTES. The Company shall promptly make all payments of principal, interest and premium, if any, in respect of the Notes on the dates and in the manner provided in the Notes and this Indenture. An installment of principal, interest or premium, if any, shall be considered paid on the date it is due if the Paying Agent (other than the Company) holds by 11:00 a.m. New York City time, on that date money in immediately available funds, deposited by the Company or an Affiliate thereof, sufficient to pay all principal, interest and premium, if any. The Company shall pay interest (including post-petition interest in any proceeding under Bankruptcy Law) on overdue principal and premium, if any, at the rate equal to 1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under Bankruptcy Law) on overdue installments of interest at the same rate to the extent lawful. Section 5.02. SEC REPORTS. (a) The Company shall file all reports and other information and documents which it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, and at the same time, the Company shall file copies of all such reports, information and other documents with the Trustee. 58 <Page> (b) In the event the Company is at any time no longer subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, so long as any Notes are outstanding, the Company will furnish to the Trustee and the Holders of the Notes (i) all quarterly and annual financial and other information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" that describes the financial condition and results of operations of the Company and its consolidated Subsidiaries and, with respect to the annual information only, a report thereon by the Company`s certified independent accountants, and (ii) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports, in each case within the time periods specified in the SEC's rules and regulations. In addition, whether or not required by the rules and regulations of the SEC, the Company will file a copy of all such information and reports with the SEC for public availability within the time periods specified in the SEC's rules and regulations (unless the SEC will not accept such a filing) and make such information available to securities analysts and prospective investors upon request. The Company shall at all times comply with TIA ss. 314(a). (c) For so long as any Notes remain outstanding (and regardless of the penultimate sentence of paragraph (b) above), the Company shall furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. Section 5.03. COMPLIANCE CERTIFICATES. (a) The Company shall deliver to the Trustee within 90 days after the end of each fiscal year, an Officers' Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto. For purposes of this paragraph, such compliance shall be determined without regard to any period of grace or requirement of notice provided under this Indenture. (b) So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the year-end financial statements delivered pursuant to Section 5.02 hereof shall be accompanied by a written statement of the Company's independent public accountants (who shall be a firm of established national reputation) that in making the examination necessary for certification of such 59 <Page> financial statements, nothing has come to their attention that would lead them to believe that the Company has violated any provisions of Articles 4, 5 or 6 hereof or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation. (c) The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, including a default or event of default under any of the Basic Documents, an Officers' Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. Section 5.04. MAINTENANCE OF OFFICE OR AGENCY. The Company shall maintain in the Borough of Manhattan, the City of New York or the City of Wilmington, Delaware, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; PROVIDED, HOWEVER, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03 hereof. Section 5.05. STAY, EXTENSION AND USURY LAWS. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted. 60 <Page> Section 5.06. RESTRICTED PAYMENTS The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or make any other payment or distribution on account of the Company's or any of its Restricted Subsidiaries' Equity Interests or to the direct or indirect holders of the Company's or any of its Restricted Subsidiaries' Equity Interests in their capacity as stockholders (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company or to the Company or a Restricted Subsidiary of the Company); (ii) purchase, redeem or otherwise acquire or retire for value any Equity Interests of the Company or any of its Restricted Subsidiaries or any direct or indirect parent of the Company (other than any such Equity Interests owned by the Company or any Consolidated Subsidiary of the Company); (iii) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Subordinated Indebtedness, except a payment of interest or principal at Stated Maturity; or (iv) make any Restricted Investment (all such payments and other actions set forth in clauses (i) through (iv) above being collectively referred to as "RESTRICTED PAYMENTS"), unless: (a) at the time of and after giving effect to such Restricted Payment, no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof, (b) the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to either clause (i) or (ii) of the first paragraph of Section 5.08 hereof; and (c) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries on and after the Issue Date (excluding Restricted Payments permitted by, and made pursuant to, clauses (ii) and (iii) and (viii) of the next succeeding paragraph), is less than the sum, without duplication and except as credited in the next succeeding paragraph, of (i) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) beginning on the last day of the fiscal quarter immediately preceding the Issue Date and ending on the last day of the fiscal quarter immediately preceding the date of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit), plus (ii) 100% of the aggregate Net Cash Proceeds received by the Company on and after November 25, 1998 as a Capital Contribution or from the issue or sale of Equity Interests of the Company (other than Disqualified Stock) or from the issue or sale of Disqualified Stock or debt securities of the Company that have been converted or exchanged into such Equity Interests (other than Equity Interests (or Disqualified Stock or converted debt securities) sold to a Subsidiary of the Company), plus the amount of Net Cash Proceeds received by the Company upon such conversion or exchange, plus (iii) the aggregate amount equal to the net reduction in Investments in Unrestricted Subsidiaries on and after the Issue Date resulting from (x) dividends, distributions, interest payments, return of capital, repayments of Investments or other transfers of assets to the Company or any Restricted Subsidiary from any Unrestricted Subsidiary, (y) proceeds realized by the Company or any Restricted 61 <Page> Subsidiary upon the sale of such Investment to a Person other than the Company or any Subsidiary of the Company, or (z) the redesignation of any Unrestricted Subsidiary as a Restricted Subsidiary, not to exceed in the case of any of the immediately preceding clauses (x), (y) or (z) the aggregate amount of Restricted Investments made by the Company or any Restricted Subsidiary in such Unrestricted Subsidiary on and after the Issue Date, plus (iv) to the extent that any Restricted Investment that was made on and after the Issue Date is sold for cash or otherwise liquidated or repaid for cash, the lesser of, to the extent paid to the Company or a Restricted Subsidiary, (A) the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (B) the initial amount of such Restricted Investment. The foregoing provisions will not prohibit (i) the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the foregoing provisions; (ii) the redemption, repurchase, retirement, defeasance or other acquisition of any Subordinated Indebtedness or Equity Interests of the Company in exchange for, or out of the Net Cash Proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than any Disqualified Stock);

(iii) the defeasance, redemption, retirement, repurchase or other acquisition of Subordinated Indebtedness with the Net Cash Proceeds from, or issued in exchange for, a substantially concurrent incurrence of Permitted Refinancing Indebtedness;

(vii) Investments in Telecommunications Assets; PROVIDED that the aggregate fair market value (measured on the date each such Investment was made or returned, as applicable), when taken together with all other Investments made pursuant to this clause (vii) that are at the time outstanding, does not exceed the sum of (y) $15.0 million, plus (z) the aggregate amount equal to the net reduction in Investments made pursuant to this clause (vii) on and after the Issue Date resulting from dividends, distributions, interest payments, return of capital, repayments of such Investments or Net Cash Proceeds realized by the Company or any Restricted Subsidiary upon the sale of such Investment to a Person other than the Company or any Subsidiary of the Company, except to the extent any such net reduction amount is included in the amount calculated 62 <Page> pursuant to clause (c) of the preceding paragraph or any other clause of this paragraph; (viii) Investments in Telecommunications Assets made after November 25, 1998 with the (x) Net Cash Proceeds, (y) the fair market value of Telecommunications Assets or (z) Equity Interests of a Person that becomes a Restricted Subsidiary (provided that the assets of such Person consist entirely or substantially entirely of Telecommunications Assets), in each case, received from the issuance or sale (other than to a Subsidiary of the Company) of Equity Interests of the Company (other than any Disqualified Stock); PROVIDED that the amount of any such Net Cash Proceeds that are utilized for any such Investment shall be excluded from clause (c) of the preceding paragraph and each other clause of this paragraph; (ix) Investments in ION; PROVIDED that the aggregate fair market value thereof (measured on the date each such Investment was made or returned, as applicable), when taken together with all other Investments made pursuant to this clause (ix) does not exceed the sum of (I) $15.0 million, plus, (II) for each fiscal year, an amount equal to the amount of cash received by the Company or any of its Restricted Subsidiaries from ION or any of its Subsidiaries during such fiscal year, except to the extent any such amount is included in the amount calculated pursuant to clause (c) of the preceding paragraph or any other clause of this paragraph, plus (III), to the extent necessary to pay reasonable and necessary operating expenses of ION, an amount not to exceed $1.0 million in each fiscal year;

The Board of Directors may not designate any Subsidiary of the Company (other than a newly created Subsidiary in which no Investment has previously been made (other than any de minimus amount required to capitalize such Subsidiary in connection with its organization)) as an Unrestricted Subsidiary (a "DESIGNATION") unless: (i) no Default or Event of Default shall have occurred and be continuing at the time of or after giving effect to such Designation; (ii) the Company would, immediately after giving effect to such Designation, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to either clause (i) or (ii) of the first paragraph of Section 5.08 hereof and (iii) the Company would not be prohibited under the Indenture from making an Investment at the time of such Designation (assuming the effectiveness of such Designation for purposes of this Section 5.06) in an amount equal to the fair market value of the net Investment of the Company and all Restricted Subsidiaries in such Subsidiary on such date. In the event of any such Designation, all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary so designated will be deemed to be an Investment made as of the time of such Designation and will reduce the 63 <Page> amount available for Restricted Payments under the first or second paragraph of this covenant, as applicable. All such outstanding Investments will be deemed to constitute Restricted Payments in an amount equal to the fair market value of such Investments at the time of such Designation. A Designation may be revoked and an Unrestricted Subsidiary may thus be redesignated a Restricted Subsidiary (a "REVOCATION") by a resolution of the Board of Directors delivered to the Trustee; PROVIDED that the Company will not make any Revocation unless: (i) no Default or Event of Default shall have occurred and be continuing at the time of or after giving effect to such Designation; and (ii) all Liens and Indebtedness of such Unrestricted Subsidiary outstanding immediately following such Revocation would, if incurred at such time, have been permitted to be incurred at such time for all purposes under this Indenture. The amount of all Restricted Payments (other than cash) shall be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company (or such Restricted Subsidiary, as the case may be) pursuant to the Restricted Payment. The fair market value of any asset(s) or securities that are required to be valued by this covenant shall be determined in good faith by the Board of Directors (such determination to be based upon an opinion or appraisal issued by an accounting, appraisal or investment banking firm of national standing if such fair market value exceeds $15.0 million). Section 5.07. DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED SUBSIDIARIES. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to (i)(a) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries (1) on its Capital Stock or (2) with respect to any other interest or participation in, or measured by, its profits, or (b) pay any indebtedness owed to the Company or any of its Restricted Subsidiaries, (ii) make loans or advances to the Company or any of its Restricted Subsidiaries or (iii) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries. However, the foregoing restrictions shall not apply to encumbrances or restrictions existing under or by reason of (a) Existing Indebtedness as in effect on the Issue Date, (b) this Indenture and the Notes, and Indebtedness ranking pari passu with the Notes provided such provisions are no more restrictive than the Notes, (c) the Credit Agreement and any Foreign Subsidiary Credit Agreement; PROVIDED that the restrictions contained in the Credit Agreement are no more restrictive, taken as a whole, than those contained in a credit agreement with terms that are commercially reasonable for a borrower that has substantially comparable Indebtedness; and PROVIDED, FURTHER, that no such provision in the Credit Agreement shall prohibit or restrict the ability of any Restricted Subsidiary to pay dividends or make other upstream distributions or other payments to the Company or any of its Restricted Subsidiaries, (d) applicable law, (e) any instrument governing Indebtedness or Capital Stock of a Person or assets acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance 64 <Page> or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; PROVIDED that in the case of Indebtedness, such Indebtedness was permitted by the terms of the Indenture to be incurred, (f) customary non-assignment provisions in leases entered into in the ordinary course of business and consistent with past practices, (g) purchase money obligations (including pursuant to Purchase Money Indebtedness obligations) for property acquired in the ordinary course of business that impose restrictions of the nature described in clause (iii) above on the property so acquired, constructed, leased or improved, (h) any agreement for the sale or other disposition of a Restricted Subsidiary that restricts distributions by that Restricted Subsidiary pending its sale or other disposition; PROVIDED that the consummation of such transaction would not result in an Event of Default or an event that, with the passing of time or giving of notice or both, would constitute an Event of Default, that such restriction terminates if such transaction is not consummated and that the consummation or abandonment of such transaction occurs within one year of the date such agreement was entered into, (i) Permitted Refinancing Indebtedness; PROVIDED that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being extended, refinanced, renewed, replaced, defeased or refunded, (j) Liens securing Indebtedness otherwise permitted to be incurred pursuant to Section 5.11 hereof that limit the right of the Company or any of its Restricted Subsidiaries to dispose of the assets subject to such Lien, (k) provisions with respect to the disposition or distribution of assets or property in joint venture agreements and other similar agreements entered into in the ordinary course of business, and (l) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business.

(ix) the Company and its Restricted Subsidiaries may incur Indebtedness solely in respect of bankers acceptances, letters of credit and performance bonds, all in the ordinary course of business in accordance with customary industry practices, in amounts and for the purposes customary in the Company's industry (other than to the extent supporting Indebtedness); (x) any Attributable Debt of the Company arising out of a sale and leaseback transaction with respect to one or more Data Centers permitted under Section 5.22; PROVIDED that (A) the aggregate principal amount of such Attributable Debt shall not exceed $50,000,000 at any one time outstanding, (B) the final maturity date of any such Attributable Debt shall not be earlier than six months after the maturity of the Notes, (C) the Weighted Average Life to Maturity of such Attributable Debt shall not be earlier than the Weighted Average Life to Maturity of the Notes and (D) the agreements and other instruments relating to such Attributable Debt shall not in any way restrict the payment or redemption of principal or interest on the Notes, or other amounts owing hereunder, the granting of Liens on property of the Company to secure the obligations of the Company hereunder, the Guarantee by any of the Subsidiaries of the Company of any of the obligations of the Company hereunder, or the execution or delivery of any modification, waiver or consent entered into in connection with this Indenture or the Notes; and 67 <Page> (xi) the incurrence by the Company or any of its Restricted Subsidiaries, as applicable, of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance or replace Indebtedness that was incurred pursuant to the first paragraph hereof or clauses (i), (ii), (iv), (v), (vi), (viii), (x) or this clause (xi) of this paragraph. Indebtedness or Preferred Stock of any Person which is outstanding at the time such Person becomes a Restricted Subsidiary of the Company (including upon designation of any Subsidiary or other Person as a Restricted Subsidiary or upon a Revocation such that such Subsidiary becomes a Restricted Subsidiary) or is merged with or into or consolidated with the Company or a Restricted Subsidiary of the Company shall be deemed to have been incurred at the time such Person becomes such a Restricted Subsidiary of the Company or is merged with or into or consolidated with the Company or a Restricted Subsidiary of the Company, as applicable. Upon each incurrence, the Company may designate pursuant to which provision of this covenant such Indebtedness is being incurred and such Indebtedness shall not be deemed to have been incurred by the Company under any other provision of this covenant, except as stated otherwise in the foregoing provisions. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, incur any Indebtedness (including Permitted Indebtedness) that is contractually subordinated in right of payment to any other Indebtedness of the Company unless such Indebtedness is also contractually subordinated in right of payment to the Notes on substantially identical terms; PROVIDED, HOWEVER, that no Indebtedness of the Company shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company solely by virtue of being unsecured. Section 5.09. ASSET SALES. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, consummate any Asset Sale, unless (i) the Company (or such Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value (as determined in good faith by the Board of Directors (including as to the value of all noncash consideration) and set forth in an Officers' Certificate delivered to the Trustee) of the assets or Equity Interests issued or sold or otherwise disposed of and (ii) at least 75% of the consideration therefor is in the form of cash and/or Cash Equivalents or Telecommunications Assets, and (iii) the Net Cash Proceeds received by the Company (or such Restricted Subsidiary, as the case may be) from such Asset Sale are applied within 360 days following the receipt of such Net Cash Proceeds, to the extent the Company (or such Restricted Subsidiary, as the case may be) elects, (a) to the permanent redemption or repurchase of outstanding Indebtedness (other than Subordinated Indebtedness) that is secured Indebtedness (including that in the case of a revolver or similar arrangement that makes credit available, such commitment is so permanently reduced by such amount) or Indebtedness of the Company or such Restricted Subsidiary that ranks equally with the Notes but has a maturity date that is prior to the maturity date of the Notes and/or (b) to reinvest such Net 68 <Page> Cash Proceeds (or any portion thereof) in Telecommunications Assets. Notwithstanding anything herein to the contrary, with respect to the reinvestment of Net Cash Proceeds, only proceeds from an Asset Sale of assets, or Equity Interests, of a Foreign Subsidiary may be used to retire Indebtedness of a Foreign Subsidiary or reinvest in assets or Equity Interests of a Foreign Subsidiary. The balance of such Net Cash Proceeds, after the application of such Net Cash Proceeds as described in the immediately preceding clauses (a) and (b), shall constitute "EXCESS PROCEEDS." When the aggregate amount of Excess Proceeds equals or exceeds $15.0 million (taking into account income earned on such Excess Proceeds), the Company will be required to make a pro rata offer to all Holders of Notes and pari passu Indebtedness with comparable provisions requiring such Indebtedness to be purchased with the proceeds of such Asset Sale (an "ASSET SALE OFFER") to purchase the maximum principal amount (or accreted value in the case of Indebtedness issued with an original issue discount) of Notes and pari passu Indebtedness that may be purchased out of the Excess Proceeds, at a purchase price in cash in an amount equal to 100% of the principal amount thereof or the accreted value thereof, as applicable, plus accrued and unpaid interest thereon to the date of purchase (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date), in accordance with the procedures set forth in Article 3 of this Indenture and the agreements governing such pari passu Indebtedness. To the extent that any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and pari passu Indebtedness tendered into such Asset Sale Offer surrendered by Holders thereof exceeds the amount of Excess Proceeds, the Company shall select the Notes and pari passu Indebtedness to be purchased on a pro rata basis in proportion to the respective principal amounts (or accreted values in the case of Indebtedness issued with an original issue discount) of the Notes and such other Indebtedness. Upon completion of such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero for purposes of the first sentence of this paragraph. The amount of (x) any liabilities (as shown on the Company's (or such Restricted Subsidiary's, as the case may be) most recent balance sheet), other than Subordinated Indebtedness of the Company or any Restricted Subsidiary that are assumed by the transferee of any such assets pursuant to an agreement that immediately releases the Company and all of its Restricted Subsidiaries from all liability in respect thereof, (y) Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale, if the Company and all of its Restricted Subsidiaries are immediately released from all Guarantees of payment of such Indebtedness and such Indebtedness is no longer the liability of the Company or any of its Restricted Subsidiaries, and (z) any securities, notes or other obligations received by the Company (or such Restricted Subsidiary, as the case may be) from such transferee that are contemporaneously (subject to ordinary settlement periods) converted by the Company (or such Restricted Subsidiary, as the case may be) into cash and/or Cash Equivalents (to the extent of the cash and/or Cash Equivalents received), will be deemed to be cash and/or Cash Equivalents for purposes of this provision. To the extent that the provisions of any securities laws or regulations shall conflict with the Asset Sale provisions of this Indenture, the Company shall comply with 69 <Page> the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Asset Sale provisions of this Indenture by virtue thereof. Section 5.10. TRANSACTIONS WITH AFFILIATES. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate (each of the foregoing, an "AFFILIATE TRANSACTION"), unless (i) such Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person and (ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions (A) involving aggregate consideration in excess of $5.0 million, the Company delivers to the Trustee a resolution of the Board of Directors set forth in an Officers' Certificate that such Affiliate Transaction is approved by a majority of the disinterested members of the Board of Directors and that, except with respect to matters governed by the Management Agreement, certifying that such Affiliate Transaction complies with clause (i) above and is in the best interests of the Company or such Restricted Subsidiary and (B) if involving aggregate consideration in excess of $15.0 million, a favorable written opinion as to the fairness to the Company of such Affiliate Transaction from a financial point of view is also obtained by the Company from an accounting, appraisal or investment banking firm of national standing with a copy delivered to the Trustee. Notwithstanding the foregoing, the following items shall not be deemed to be Affiliate Transactions: (i) (a) the entering into, maintaining or performance of any employment contract, collective bargaining agreement, benefit plan, program or arrangement, related trust agreement or any other similar arrangement for or with any employee, officer or director heretofore or hereafter entered into in the ordinary course of business, including vacation, health, insurance, deferred compensation, retirement, savings or other similar plans, (b) the payment of compensation, performance of indemnification or contribution obligations, or an issuance, grant or award of stock, options, or other equity-related interests or other securities, to employees, officers or directors in the ordinary course of business, (c) any transaction with an officer or director in the ordinary course of business not involving more than $100,000 in any one case, or (d) Management Advances and payments in respect thereof, (ii) transactions between or among the Company and/or its Restricted Subsidiaries, (iii) payment of reasonable directors fees, (iv) any sale or other issuance of Equity Interests (other than Disqualified Stock) of the Company, (v) Affiliate Transactions in effect or approved by the Board of Directors on the Issue Date, including any amendments thereto (provided that the terms of such amendments are not materially less favorable to the Company than the terms of such agreement prior to such amendment), (vi) transactions with respect to capacity between the Company or any Restricted Subsidiary and any Unrestricted Subsidiary or other Affiliate and joint sales and marketing pursuant to an agreement or agreements between the Company or any Restricted Subsidiary and any Unrestricted Subsidiary or other Affiliate (provided that in the case of this clause (vi), such agreements are on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that could have been obtained at the time of such transaction in an arm's-length 70 <Page> transaction with an unrelated third party or, in the case of a transaction with an Unrestricted Subsidiary, ION or another Affiliate, are either (x) entered into in connection with a transaction involving the selection by a customer of cable system capacity entered into in the ordinary course of business or (y) involve the provision by the Company or a Restricted Subsidiary to an Unrestricted Subsidiary, ION or another Affiliate of sales and marketing services, operations, administration and maintenance services or development services for which the Company or such Restricted Subsidiary receives a fair rate of return (as determined by the Board of Directors and set forth in an Officers' Certificate delivered to the Trustee) above its expenses of providing such services), and (vii) Restricted Payments that are permitted by Section 5.06 hereof. Section 5.11. LIENS. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) upon any of their property or assets, now owned or hereafter acquired, or upon any income or profits therefrom unless all payments due under this Indenture and the Notes are secured (except as provided in the next clause) on an equal and ratable basis with the obligations so secured and no Lien shall be granted or be allowed to exist which secures Subordinated Indebtedness except with respect to Acquired Debt, in which case, however, such Liens must be made junior and subordinate to the Liens granted to the Holders of the Notes. Section 5.12. FURTHER INSTRUMENTS AND ACTS. Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. Section 5.13. LIQUIDATION. The Company shall not adopt any plan of liquidation which provides for, contemplates or the effectuation of which is preceded by (i) the sale, lease, conveyance or other disposition of all or substantially all the assets of the Company otherwise than substantially as an entirety in accordance with Article 6 and (ii) the distribution of all or substantially all of the proceeds of such sale, lease, conveyance or other disposition and the remaining assets of the Company to holders of Class A Common Stock of the Company, unless the Company shall in connection with the adoption of such plan make provision for, or agree that prior to making any liquidating distributions it will make provision for, the satisfaction of the Company's obligations under this Indenture and under the Notes as to the payment of principal, interest and premium, if any, thereof. Section 5.14. CHANGE OF CONTROL. (a) Upon the occurrence of a Change of Control, each Holder of Notes will have the right to require the Company to purchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder's Notes pursuant to the offer described below (the "CHANGE OF CONTROL OFFER") at a purchase price in cash equal to 100% of the 71 <Page> aggregate principal amount thereof (the "CHANGE OF CONTROL PAYMENT") plus accrued and unpaid interest and premium, if any, thereon to the date of purchase (subject to the right of Holders of record on the relevant Record Date to receive interest and premium, if any, due on the relevant Interest Payment Date); PROVIDED, however, that the Company shall not be obligated to repurchase Notes pursuant to this covenant in the event that it has exercised its rights to redeem all of the Notes as described in Section 3.07 hereof. Within 30 days following any Change of Control, the Company will mail a notice to each Holder (with a copy to the Trustee) describing the transaction or transactions that constitute the Change of Control and offering to purchase Notes on the date specified in such notice, which date shall be no earlier than 30 and no later than 60 days from the date such notice is mailed (the "CHANGE OF CONTROL PAYMENT DATE"), in accordance with the procedures required by this Indenture and described in such notice. The Company will comply with the requirements of Rule 14e-l under the Exchange Act and any other securities laws and regulations to the extent such laws and regulations are applicable in connection with the purchase of Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with any of the provisions of this Section 5.14, the Company will comply with the applicable securities laws and regulations and will be deemed not to have breached its obligations under this covenant by virtue thereof. (b) On the Change of Control Payment Date, the Company will, to the extent lawful, (1) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer, (2) deposit with the Paying Agent an amount equal to the Change of Control Payment plus accrued and unpaid interest and premium, if any, thereon in respect of all Notes or portions thereof so tendered and (3) deliver or cause to be delivered to the Trustee Notes so accepted together with an Officers' Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company.

The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. (c) Notwithstanding anything to the contrary set forth in this Section 5.14, the Company shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 5.14, and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. Section 5.15. CORPORATE EXISTENCE. Subject to Article 6, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect the corporate, partnership or other 72 <Page> existence, rights (charter and statutory), licenses and franchises of the Company and each of its Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company and each of its Subsidiaries; PROVIDED HOWEVER, that the Company shall not be required to preserve any such right, license or franchise if the Board of Directors shall determine in good faith that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders. Section 5.16. PAYMENT OF TAXES AND OTHER CLAIMS. The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, all taxes, assessments and governmental charges levied or imposed upon the Company or any of its Subsidiaries or upon the income, profits or property of the Company or any of its Subsidiaries; PROVIDED HOWEVER, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings promptly instituted and diligently concluded and shall not have been finally determined or the period within which such proceedings may be initiated shall not have expired. Section 5.17. MAINTENANCE OF PROPERTIES. The Company will cause all properties owned by the Company or any Subsidiary, or used, useful or held for use in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; PROVIDED, HOWEVER, that nothing in this Section shall prevent the Company or any Subsidiary from discontinuing the maintenance of any of such properties, if such discontinuance or disposal is, in the judgment of the Company, desirable in the conduct of its business or the business of any of its Subsidiaries and not disadvantageous in any material respect to the Holders. Section 5.18. INSURANCE. The Company will at all times keep all of its and its Subsidiaries' properties which are of an insurable nature insured with insurance, believed by the Company to be responsible, against loss or damage to the extent that property of similar character is usually so insured by corporations similarly situated and owning like properties. Section 5.19. RATING. The Company shall use its reasonable best efforts to have the Notes rated by an established rating agency (which, for so long as is commercially reasonable to do so, will be either Standard & Poor's Rating Group, a division of McGraw-Hill, Inc., and 73 <Page> Moody's Investors Service) as requested by the Initial Purchaser and to maintain a rating through and including the Stated Maturity for the Notes; PROVIDED, HOWEVER, that the Company shall not be required to maintain a specified rating. Section 5.20. NO REDEMPTION OF AFFILIATE NOTES. For so long as the Notes are outstanding, the Company shall not make any principal payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value the Affiliate Notes pursuant to the terms thereof without the prior written consent of the Initial Purchaser unless the Company simultaneously prepays or redeems an equal aggregate principal amount of these Notes and the New 6.15% Notes (on a pro rata basis) in accordance with the terms of this Indenture and the New 6.15% Notes Indenture, respectively; PROVIDED, HOWEVER, that this Section 5.20 shall only apply when all or a portion of the Notes are beneficially owned by the Initial Purchaser or any of its Affiliates. Section 5.21. PAYMENTS FOR CONSENT. The Company will not, and will not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid or is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. Section 5.22. SALE AND LEASE-BACK TRANSACTIONS. The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, enter into any arrangement, directly or indirectly, with any Person whereby it shall sell or transfer any property, real or personal, used or useful in its business, whether now owned or hereafter acquired, and thereafter rent or lease such property or other property which it intends to use for substantially the same purpose or purposes as the property being sold or transferred; PROVIDED that the Company may enter into any such arrangement with respect to one or more Data Centers to the extent that the Indebtedness or Attributable Debt arising in connection therewith is permitted under Section 5.08(b)(x). 74 <Page> Section 5.23. USE OF PROCEEDS. The Company shall use the proceeds from the sale of the Notes solely to purchase the Pledged Securities (as such term is defined in the Depositary Agreement) the proceeds of which will be used solely to finance all or any part of the cost of the engineering, construction, installation, acquisition, lease, development or improvement of Telecommunications Assets used by the Company or any of its Subsidiaries only as permitted by Section 4.09 of each of the Senior Note Indentures. Section 5.24. SALES OF ALLOCATED CAPACITY. (a) Any sale, transfer or other disposition by the Company of its ownership interest in any Allocated Capacity pursuant to Section 12 of the C&MA (other than an IRU), whether as an assignment of any of its interests in the C&MA or otherwise (an "ALLOCATED CAPACITY TRANSFER"), will be governed by this Section 5.24. (b) If prior to the Phase II Upgrade RFS Date, the Company effects an Allocated Capacity Transfer, and after giving effect to such Allocated Capacity Transfer, the Company's Allocated Capacity is less than 36 STM-1s, then the proceeds (the "ALLOCATED CAPACITY PROCEEDS") of such Allocated Capacity Transfer shall be deposited in the Disbursement Account. (c) If after the Phase II Upgrade RFS Date, the Company effects an Allocated Capacity Transfer, and after giving effect to such Allocated Capacity Transfer, the Company's Allocated Capacity is less than 140 STM-1s, the Company will be required to make a pro rata offer to all Holders of Notes (an "OFFER TO PURCHASE") within 5 Business Days of the receipt of the Allocated Capacity Proceeds of such Allocated Capacity Transfer to purchase the maximum principal amount of Notes that may be purchased out of such Allocated Capacity Proceeds, at a purchase price in cash in an amount equal to 100% of the principal amount thereof or the accreted value thereof, as applicable, plus accrued and unpaid interest thereon to the date of purchase (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date), in accordance with the procedures set forth in Section 3.08 hereof.

(a) The Company shall not, directly or indirectly, consolidate or merge with or into (whether or not the Company is the surviving corporation), or sell, assign, 75 <Page> transfer, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another Person unless: (i) the Company is the surviving corporation or the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, conveyance or other disposition shall have been made is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia; (ii) the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, conveyance or other disposition shall have been made assumes all the obligations of the Company under the Registration Rights Agreement, the Notes, and this Indenture pursuant to a supplemental indenture in a form reasonably satisfactory to the Trustee; (iii) no Default or Event of Default (or an event that, with the passing of time or giving of notice or both, would constitute an Event of Default) shall exist or shall occur immediately after giving effect on a pro forma basis to such transaction; and (iv) the Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with the Indenture.

ACCELERATION. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding may declare all the Notes to be due and payable immediately; PROVIDED, HOWEVER that if the Senior Notes immediately become due and payable, the principal of and all accrued interest on the Notes shall become due and payable without further action or notice. Notwithstanding the foregoing, if an Event of Default specified in clause (g) or (h) of Section 7.01 hereof occurs with respect to the Company or any Significant Subsidiary, all outstanding Notes shall be due and payable immediately without further action or notice. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of all of the Holders rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived. Section 7.03. OTHER REMEDIES. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. Section 7.04. WAIVER OF PAST DEFAULTS. Holders of not less than a majority in aggregate principal amount of the then outstanding Notes (or, with respect to a provision of this Indenture that may only be amended by the Holders of not less than 50% in aggregate principal amount of the then outstanding Notes, the Holders of not less than 50% in aggregate principal amount of the then outstanding Notes) by written notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium or interest on, the Notes (including in connection with an offer to purchase) which cannot be modified or amended without the consent of the Holder of each outstanding Note affected. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 79 <Page> Section 7.05. CONTROL BY MAJORITY. Holders of Notes may not enforce this Indenture or the Notes except as provided herein. Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it, including any exercise of any remedy under the Security Documents. The Trustee may, however, refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. Section 7.06. LIMITATION ON SUITS. A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if: (a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; (b) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy; (c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and (e) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. Section 7.07. RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT. Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. Section 7.08. COLLECTION SUIT BY TRUSTEE.

To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 8.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. Section 7.10. PRIORITIES. If the Trustee collects any money or other consideration pursuant to this Article 7, it shall pay out the money in the following order: FIRST: to the Trustee, its agents and counsel for amounts due under Section 8.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; SECOND: to Holders of Notes for amounts due and unpaid on the Notes for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal and interest, respectively, and THIRD: to the Company or to such party as a court of competent jurisdiction shall direct. 81 <Page> The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 7.10. Section 7.11. UNDERTAKING FOR COSTS. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the cost of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 7.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 7.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes. Section 7.12. AUTHORIZATION OF TRUSTEE TO TAKE OTHER ACTIONS. The Trustee is hereby authorized to enter into and take any actions or deliver such consents required by or requested under each of the Security Documents, the Intercreditor Agreement and such other documents as directed by the Holders of a majority of outstanding aggregate principal amount of the Notes. If at any time any action by or the consent of the Trustee is required under any of the Security Documents, the Intercreditor Agreement or any other document entered into by the Trustee at the direction of a majority of the Holders of outstanding aggregate principal amount of the Notes, such action or consent shall be taken or given by the Trustee upon the consent to such action by the Holders of a majority of outstanding aggregate principal amount of the Notes. ARTICLE 8. TRUSTEE Section 8.01. DUTIES OF TRUSTEE. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

However, the Trustee shall examine the certificates (or similar documents) and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein or otherwise verify the contents thereto).

(d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), (c) and (e) of this Section 8.01. (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability.

Section 8.03. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 8.10 and 8.11 hereof. Section 8.04. TRUSTEE'S DISCLAIMER. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes, or the Security Documents, it shall not be accountable for the Company's use of the proceeds from the Notes or any money 84 <Page> paid to the Company or upon the Company's direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. Section 8.05. NOTICE OF DEFAULTS. (a) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture. (b) If a Default or Event of Default occurs and is continuing and if it is known to the Trustee in accordance with the provisions of paragraph (a) of this Section 8.05, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. Section 8.06. REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES. Within 60 days after each May 15th following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA ss. 313(a) (but if no event described in TIA ss. 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA ss. 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA ss. 313(c). A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the SEC and each stock exchange on which the Notes are listed in accordance with TIA ss. 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange. Section 8.07. COMPENSATION AND INDEMNITY. The Company shall pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder as the parties shall agree from time to time.

The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel. 85 <Page> The Company shall indemnify the Trustee and hold it harmless against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture and the Security Documents, including the costs and expenses of enforcing this Indenture and the Security Documents against the Company (including this Section 8.07) and defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its gross negligence or bad faith. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld or delayed.

To secure the Company's payment obligations in this Section, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 7.01(g) or (h) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. The Trustee shall comply with the provisions of TIA ss. 313(b)(2) to the extent applicable. Section 8.08. REPLACEMENT OF TRUSTEE. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section 8.08. The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of Notes of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: (a) the Trustee fails to comply with Section 8.10 hereof; (b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; 86 <Page> (c) a custodian or public officer takes charge of the Trustee or its property; or (d) the Trustee becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of Notes of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply with Section 8.10 hereof, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this indenture. The successor Trustee shall mail a notice of its succession to Holders of the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 8.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 8.08, the Company's obligations under Section 8.07 hereof shall continue for the benefit of the retiring Trustee. The Company shall take such actions as are necessary or desirable, in the opinion of counsel to the successor Trustee to maintain the perfection of the Liens created by the Security Documents all at the expense of the Company. Section 8.09. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee. Section 8.10. ELIGIBILITY; DISQUALIFICATION. There shall at all times be a Trustee (or in the case of a banking corporation included in a bank holding company system, the related bank holding company) hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal 87 <Page> or state authorities and that has a combined capital and surplus of at least $100.0 million as set forth in its most recent published annual report of condition. This Indenture shall always have a Trustee who satisfies the requirements of TIA ss. 310(a)(1), (2) and (5). The Trustee is subject to TIA ss. 310(b). Section 8.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. The Trustee is subject to TIA ss. 311(a), excluding any creditor relationship listed in TIA ss. 311(b). A Trustee who has resigned or been removed shall be subject to TIA ss. 311(a) to the extent indicated therein. Section 8.12. CO-TRUSTEE. It is the purpose of this Indenture that there shall be no violation of any law of any jurisdiction denying or restricting the right of certain banking corporations or associations to transact business as trustee as contemplated herein in such jurisdiction. The following provisions of this Section 8.12 are included in the event that it is necessary that the Trustee appoint an additional institution as a separate Trustee or Co-Trustee. In the event of the incapacity or lack of authority of the Trustee, by reason of any present or future law of any jurisdiction, to exercise any of the rights, powers and trusts herein granted to the Trustee or to take any other action which may be necessary or desirable in connection therewith, each and every remedy, power, right, claim, demand, cause of action, immunity, estate, title, interest and lien expressed or intended by this Indenture to be exercised by or vested in or conveyed to the Trustee with respect thereto shall be exercisable by and vest in such separate Trustee or Co-Trustee but only to the extent necessary to enable the separate Trustee or Co-Trustee to exercise such rights, powers and trusts, and every covenant and obligation necessary to the exercise thereof shall run to and be enforceable by such separate Trustee or Co-Trustee. Should any deed, conveyance or instrument in writing from the Company be required by the separate Trustee or Co-Trustee so appointed by the Trustee in order to more fully and certainly vest in and confirm to him or it such properties, rights, powers, trusts, duties and obligations, any and all such deeds, conveyances and instruments shall, on request, be executed, acknowledged and delivered by the Company. In case any separate Trustee or Co-Trustee or a successor to either, shall die, become incapable of acting, resign or be removed, all the estates, properties, rights, powers, trusts, duties and obligations of such separate Trustee or Co-Trustee, so far as permitted by law, shall vest in and be exercised by the Trustee until the appointment of a new Trustee or successor to such separate Trustee or Co-Trustee. 88 <Page> ARTICLE 9.

For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be "OUTSTANDING" only for the purposes of Section 9.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all of its obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments delivered to it by the Company acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due from the trust referred to below; (b) the Company's obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust; (c) the rights, powers, trusts, duties and immunities of the Trustee, and the Company's obligations in connection therewith; (d) the Legal Defeasance provisions of this Indenture; and (e) the obligations of the Company under Article 4 which shall not terminate until the payment at the redemption date specified in Article 3 or the Stated Maturity of the Notes.

For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 7.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby.

Notwithstanding Section 10.02 hereof, the Company and the Trustee may amend or supplement this Indenture, the Notes or the Security Documents without the consent of any Holder of a Note: (a) to cure any ambiguity, omission, defect or inconsistency; (b) to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions of Article 2 hereof (including the related definitions) in a manner that does not adversely affect any Holder; (c) to provide for the assumption of the Company's obligations to the Holders of the Notes by a successor to the Company pursuant to Article 6 hereof; (d) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the rights hereunder of any Holder of the Note; (e) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; (f) to add to the covenants of the Company for the benefit of the Holders or to surrender any right or power herein conferred upon the Company; or (g) to effect any change to the transfer and exchange restrictions and security delivery procedures contained in Article 2 in order to conform with changes in any applicable law or Applicable Procedures. Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture or amendment to a Security Document, and upon receipt by the Trustee of the documents described in Section 8.02 hereof, the Trustee shall join with the Company in the execution of any amended or supplemental indenture or amendment to a Security Document authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture or amendment to a Security Document that affects its own rights, duties or immunities under this Indenture, the Security Documents or otherwise. Section 10.02. WITH CONSENT OF HOLDERS OF NOTES. Except as provided below in this Section 10.02, the Company and the Trustee, may amend or supplement this Indenture, the Notes and the Security Documents with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes voting as a single class (including consents obtained in connection 93 <Page> with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 7.04 and 7.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Notes or the Security Documents may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). In addition, without the consent of the Holders of at least 85% in aggregate principal amount of the Notes then outstanding, an amendment or waiver may not make any change to, or be effective with respect to, any of the provisions of this Indenture or the Security Documents relating to the Collateral. Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 8.02 hereof, the Trustee, shall join with the Company in the execution of such amended or supplemental indenture or amendment to a Security Document unless such amended or supplemental indenture or amendment to a Security Document directly affects the Trustee's own rights, duties or immunities under this Indenture, the Security Documents or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture or amendment to a Security Document, as applicable. It shall not be necessary for the consent of the Holders of Notes under this Section 10.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver under this Section 10.02 becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to the provisions of this Section 10.02 and Sections 7.04 and 7.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment or waiver under this Section 10.02 may not (with respect to any Notes held by a non-consenting Holder): (a) change the Stated Maturity on any Note, or reduce the principal thereof or the rate (or extend the time for payment) of interest thereon or any premium payable upon the redemption at the option of the Company thereof, or change the place of payment where, or the coin or currency in which, any Note or any premium or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption at the option of the Company, on or after the redemption date), or reduce the Change of Control Payment after the Change of Control has occurred; 94 <Page> (b) alter the provisions (including the defined terms used herein) regarding the right of the Company to redeem the Notes as a right, or at the option, of the Company in a manner adverse to the Holders: (c) reduce the percentage in principal amount of Notes outstanding whose Holders must consent to an amendment, supplement or waiver provided for in this Indenture; (d) release all or substantially all of the Collateral from the Lien of this Indenture or the Security Documents (except in accordance with the provisions thereof); or (e) modify any of the waiver provisions, except to increase any required percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each outstanding Note affected thereby. Section 10.03. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental indenture that complies with the TIA as then in effect. Section 10.04. REVOCATION AND EFFECT OF CONSENTS. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. An amendment or waiver shall become effective upon receipt by the Trustee of the requisite number of written consents under Section 10.01 or 10.02 as applicable. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders of Notes entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who held Notes at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. Section 10.05. NOTATION ON OR EXCHANGE OF NOTES. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange 95 <Page> for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. Section 10.06. TRUSTEE TO SIGN AMENDMENTS. ETC. Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article 10 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee and all other conditions to the execution and delivery of such amendment or supplement set forth in this Article 10 are fulfilled. The Company may not sign an amendment or supplemental indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 8.01 hereof) shall be fully protected in relying upon an Officers' Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and that such amendment is the legal, valid and binding obligation of the Company, enforceable against it in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 10.03). ARTICLE 11. SATISFACTION AND DISCHARGE Section 11.01. SATISFACTION AND DISCHARGE OF INDENTURE. This Indenture shall be discharged and will cease to be of further effect as to all Notes issued hereunder, when either: (a) all such Notes theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company) have been delivered to the Trustee for cancellation; or (b) (i) all such Notes not theretofore delivered to such Trustee for cancellation have become due and payable by reason of the making of a notice of redemption, repurchase or otherwise or will become due and payable within one year and the Company has irrevocably deposited or caused to be deposited with such Trustee as trust funds in trust an amount of money sufficient to pay and discharge the entire Indebtedness on such Notes not theretofore delivered to the Trustee for cancellation for principal and accrued interest to the date of maturity, redemption or repurchase; (ii) no Default or Event of Default with respect to this Indenture or the Notes shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit and such deposit will not result in a breach or violation or constitute a default under, any other instrument to which the Company is a party or by which the Company is bound; 96 <Page> (iii) the Company has paid or caused to be paid all sums payable by it under this Indenture; and (iv) the Company has delivered irrevocable written instructions to the Trustee under this Indenture to apply the deposited money toward the payment of such Notes at maturity or the redemption date, as the case may be. In addition, the Company must deliver an Officers' Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company's obligations under this Indenture and the Notes shall be revived and reinstated as though such deposit had occurred pursuant to Section 11.01 hereof; PROVIDED that if the Company has made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent. ARTICLE 12. COLLATERAL AND SECURITY Section 12.01. SECURITY. The due and punctual payment of the principal of and interest on the Notes when and as the same shall be due and payable, whether on an Interest Payment Date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of and interest on the Notes and performance of all other obligations of the Company to the Holders of Notes, or the Trustee under this Indenture and the Notes, according to the terms hereunder or thereunder, shall be secured to the extent provided in the Security Documents which the Company has entered into simultaneously with the execution of this Indenture. Each Holder of Notes, by its acceptance thereof, consents and agrees to the terms of the Security Documents (including, without limitation, the provisions providing for foreclosure and release of Collateral) as the same may be in effect or may be amended from time to time in accordance with their terms, authorizes and directs the Trustee to enter into the Security 97 <Page> Documents and to perform its obligations and exercise its rights thereunder in accordance therewith.

The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. 5. OPTIONAL REDEMPTION. The Notes shall not be redeemable at the Company's option prior to September 15, 2006. Thereafter, the Notes shall be subject to redemption at any time at the option of the Company, in whole or in part upon not less than 45 nor more than 60 days' notice, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest thereon to the applicable redemption date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date), if redeemed during the twelve-month period beginning on September 15 (September 17 for the year 2007) of the years indicated below: <Table> <Caption> PERCENTAGE OF PRINCIPAL YEAR AMOUNT ---- ------ 2006 ............................................................ 104.250% 2007 ............................................................ 103.190% 2008 ............................................................ 102.130% 2009 ............................................................ 101.060% 2010 and thereafter ............................................. 100.000% </Table> Any redemption pursuant to this Section 5 shall be made pursuant to the provisions of Section 3.01 through 3.06 of the Indenture. 6. MANDATORY REDEMPTION. Except as set forth in this Section 6, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes. If (A) the Requisite Company Vote has not been received by the date that is six months after the date of the Indenture or (B) for any reason the C&MA Assignment is deemed to be an invalid or ineffective assignment under the terms of the C&MA, each Holder of the Notes will have the right to require the Company to purchase all of such Holder's Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest thereon to the date of purchase (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date).

Within 30 days following any Change of Control, the Company will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. 8. CONVERSION OF NOTE BY HOLDER. (a) Subject to the provisions of Section 4.01 of the Indenture, from and after the time that the Requisite Company Vote is received, a Holder of a Note may convert such Note at the Conversion Price (as hereinafter defined) then in effect into Class A Common Stock (i) at any time after the Regulatory Relief Date, if at such time such Holder is a Regulated Person, or (ii) at any time, if such Holder is not a Regulated Person. The number of shares of Class A Common Stock issuable upon conversion of a Note shall be determined by dividing the principal amount of the Note or portion thereof surrendered for conversion by the Conversion Price in effect on the Conversion Date. The initial Conversion Price is $0.53875 and is subject to adjustment or voluntary reduction as provided in Article 4 of the Indenture (the "CONVERSION PRICE"). (b) A Holder of Notes may convert a portion of a Note equal to $1,000 or any integral multiple thereof; PROVIDED, HOWEVER, that provisions of Article 4 of the Indenture that apply to conversion of all of a Note also apply to conversion of a portion of a Note. (c) A Holder of Notes is not entitled to any rights of a holder of Class A Common Stock until such Holder has converted its Notes to Class A Common Stock, and only to the extent such Notes are deemed to have been converted into Class A Common Stock pursuant to Article 4 of the Indenture. (d) In the event that (i) the Company takes any action which would require an adjustment in the Conversion Price; (ii) the Company consolidates or merges with, or transfers all or substantially all of its property and assets to, another corporation and shareholders of the Company must approve the transaction; or (iii) there is a dissolution or liquidation of the Company, the Company shall mail to the Holders and file with the Trustee a notice stating the proposed record or effective date, as the case may be. The Company shall mail the notice before such date to the same extent as such notice is mailed to the stockholders of the Company. (e) The Conversion Price shall be adjusted from time to time by the Company as follows: (i) In case the Company shall (A) pay a dividend in shares of Class A Common Stock to the holders of the Class A Common Stock, (B) make a distribution in shares of Class A Common Stock to the holders of the Class A Common Stock, (C) subdivide or split its outstanding Class A Common Stock into a larger number of shares, A-7 <Page> or (D) combine its outstanding Class A Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior thereto shall be adjusted so that the Holder of any Note thereafter surrendered for conversion shall be entitled to receive that number of shares of Class A Common Stock which it would have owned or been entitled to receive had such Note been converted immediately prior to the happening of such event. An adjustment made pursuant to this subsection (i) shall become effective as of the close of business on the record date in the case of a dividend in shares or distribution and shall become effective as of the close of business on the effective date in the case of a subdivision, split or combination. (ii) In case (A) the Company shall issue rights or warrants to all or substantially all holders of its Class A Common Stock entitling them (for a period commencing no earlier than the record date described below and expiring not more than 60 days after such record date) to subscribe for or purchase shares of Class A Common Stock (or securities convertible into Class A Common Stock) at a price per share less than the Current Market Price per share of Class A Common Stock (as determined in accordance with subsection (vii) of this Section 8(e)) at the record date for the determination of shareholders entitled to receive such rights or warrants or (B) the Company shall sell or issue any Class A Common Stock and the consideration per share of Class A Common Stock to be paid upon such issuance or subscription is more than 5% less than the Current Market Price per share of Class A Common Stock or the Company shall sell or issue warrants, rights or other convertible securities to subscribe for or purchase shares of Class A Common Stock at a price per share more than 5% less than the Current Market Price per share of Class A Common Stock (each as determined in accordance with subsection (vii) of this Section 8) on the date of such sale or issuance, the Conversion Price in effect as of the close of business on the record date thereto shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect on the record date by a fraction of which the numerator shall be the number of shares of Class A Common Stock outstanding on such record date, plus the number of shares which the aggregate offering price of the total number of shares of Class A Common Stock so offered (or the aggregate conversion price of the Notes so offered) would purchase at such Current Market Price, and of which the denominator shall be the number of shares of Class A Common Stock outstanding on such record date plus the number of additional shares of Class A Common Stock offered (or into which the convertible securities so offered are convertible). Such adjustment shall be made successively whenever any such rights, warrants or convertible securities are issued, and shall become effective as of the close of business on such record date. If at the end of the period during which such rights or warrants are exercisable not all rights or warrants shall have been exercised, the adjusted Conversion Price shall be immediately readjusted to what it would have been based upon the number of additional shares of Class A Common Stock actually issued (or the number of shares of Class A Common Stock issuable upon conversion of Notes actually issued). (iii) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock, cash (excluding (x) any regular cash dividend on the Common Stock to the extent that the aggregate cash dividend per share of Common Stock in any four fiscal quarters does not exceed the greater of (A) the amount per share of Common Stock of the cash dividend on the Common Stock for the preceding four A-8 <Page> fiscal quarters to the extent that such dividend for the preceding four fiscal quarters did not require any adjustment of the Conversion Price pursuant to this Section 8(e)(iii) (as adjusted to reflect subdivisions or combinations of the Common Stock), and (B) 3.75% of the arithmetic average of the Closing Prices (as set forth in Section 8(e)(vii)) during the ten Trading Days immediately prior to the date of declaration of such dividend, (y) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary, and (z) any cash that is distributed as part of a distribution requiring a Conversion Price adjustment pursuant to Section 8(e)(v)), then, in such case, the Conversion Price shall be decreased so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the record date of such action by a fraction of which the numerator shall be the Current Market Price of the Class A Common Stock on such record date less the amount of cash so distributed (and not excluded as provided above) applicable to one share of Common Stock and the denominator shall be the Current Market Price of the Class A Common Stock on such record date, such decrease shall be effective immediately prior to the opening of business on the day following the record date of such action; PROVIDED, HOWEVER, that in the event the portion of cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Class A Common Stock on such record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion the amount of cash such Holder would have received had such Holder converted each Note on the record date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. If any adjustment is required to be made as set forth in this Section 8(e)(iii) as a result of a distribution that is a regular dividend, such adjustment shall be based upon the amount by which such distribution exceeds the amount of the regular cash dividend permitted to be excluded pursuant hereto. If an adjustment is required to be made as set forth in this Section 8(e)(iii) above as a result of a distribution that is not a regular dividend, such adjustment shall be based upon the full amount of the distribution. (iv) In case a tender or exchange offer made by the Company or any Subsidiary of the Company for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of Common Stock having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) that, as of the last time (the "EXPIRATION TIME") tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), exceeds the Current Market Price of the Class A Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Price shall be decreased so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the Expiration Time by a fraction of which the numerator shall be the product of the number of Class A Common Stock outstanding (including any tendered or exchanged shares) on the Expiration Time multiplied by the Current Market Price of the Class A Common Stock on the Trading Day next succeeding the Expiration Time, less the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of A-9 <Page> all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "PURCHASED SHARES") and the denominator shall be the product of the number of Class A Common Stock outstanding (less any Purchased Shares) on the Expiration Time and the Current Market Price of the Class A Common Stock on the Trading Day next succeeding the Expiration Time, such reduction to become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender or exchange offer has not been made. (v) In case the Company shall distribute to all or substantially all holders of its Class A Common Stock any shares of capital stock of the Company (other than Class A Common Stock), evidences of indebtedness or other non-cash assets (including securities of any Person), or shall distribute to all holders of its Class A Common Stock rights or warrants to subscribe for or purchase any of its securities (excluding those referred to in subsection (ii) of this Section 8(e), then in each such case the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect as of the close of business on the record date for such distribution by a fraction of which the numerator shall be the Current Market Price of the Class A Common Stock on the record date mentioned below less the fair market value on such record date (as reasonably determined by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and set forth in a Board Resolution delivered to the Trustee in an Officers' Certificate) of the portion of the capital stock, evidences of indebtedness or other assets so distributed or of such rights or warrants applicable to one share of Class A Common Stock (determined on the basis of the number of shares of Class A Common Stock outstanding on the record date), and of which the denominator shall be the Current Market Price per share (as determined in accordance with subsection (vii) of this Section 8(e)) of the Class A Common Stock on such record date. Such adjustment shall become effective as of the close of business on the record date for the determination of shareholders entitled to receive such distribution. Notwithstanding the foregoing, in the event that the Company shall distribute rights or warrants (other than those referred to in subsection (ii) of this Section 8(e)) ("RIGHTS") pro rata to holders of Class A Common Stock, the Company may, in lieu of making any adjustment pursuant to this Section 8(e), make proper provision so that each holder of a Note who converts such Note (or any portion thereof) after the record date for such distribution and prior to the expiration or redemption of the Rights shall be entitled to receive upon such conversion, in addition to the shares of Class A Common Stock issuable upon such conversion (the "CONVERSION SHARES"), a number of Rights to be determined as follows: (i) if such conversion occurs on or prior to the date for the distribution to the holders of Rights of separate certificates evidencing such Rights (the "DISTRIBUTION DATE"), the same number of Rights to which a holder of a number of shares of Class A Common Stock equal to the number of Conversion Shares is entitled at the time of such conversion in accordance with the terms and provisions of and applicable to the Rights and (ii) if such conversion occurs after the Distribution Date, the same number of Rights to which a holder of the number of shares of Class A A-10 <Page> Common Stock into which the principal amount of the Note so converted was convertible as of the close of business on the Distribution Date would have been entitled on the Distribution Date in accordance with the terms and provisions of and applicable to the Rights. (vi) In case of a tender or exchange offer made by a Person other than the Company or any Subsidiary of the Company for an amount which increases the offeror's ownership of Class A Common Stock to more than 35% of the Class A Common Stock outstanding and shall involve the payment by such Person of consideration per share of Class A Common Stock having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a Board Resolution) at the last time (the "TENDER EXPIRATION TIME") tenders or exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended) that exceeds the Current Market Price per share of the Class A Common Stock on the Trading Day next succeeding the Tender Expiration Time, and in which, as of the Tender Expiration Time, the Board of Directors is not recommending rejection of the offer, the Conversion Price shall be decreased so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the Tender Expiration Time by a fraction of which the numerator shall be the number of shares of Class A Common Stock outstanding (including any tendered or exchanged shares) at the Tender Expiration Time multiplied by the Current Market Price of the Class A Common Stock on the Trading Day next succeeding the Tender Expiration Time and the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Tender Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "ACCEPTED PURCHASED SHARES") and (y) the product of the number of shares of Class A Common Stock outstanding (less any Accepted Purchased Shares) at the Tender Expiration Time and the Current Market Price of the Class A Common Stock on the Trading Day next succeeding the Tender Expiration Time, such decrease to become effective immediately prior to the opening of business on the day following the Tender Expiration Time. In the event that such Person is obligated to purchase shares pursuant to any such tender or exchange offer, but such Person is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender or exchange offer had not been made. Notwithstanding the foregoing, the adjustment described in this Section 8(e)(vi) shall not be made if: (a) as of the Tender Expiration Time, the offering documents with respect to such offer disclose a plan or intention to cause the Company to engage in any transaction described in Article 6 of the Indenture; or (b) the Initial Purchaser or any of its Affiliates does not beneficially own all of the Notes. (vii) For purposes of this Section 8(e), the following terms shall have the meaning indicated: "CLOSING PRICE" with respect to any securities on any date shall mean the closing sale price, regular way, on such day or, in case no such sale takes place A-11 <Page> on such day, the average of the reported closing bid and asked prices, regular way, in each case on the New York Stock Exchange, or, if such security is not listed or admitted to trading on such Exchange, on the principal security exchange or quotation system in the United States on which such security is quoted or listed or admitted to trading, or, the average of the closing bid and asked prices of such security on the over-the-counter market on the day in question as reported by the Nasdaq National Market or a similar generally accepted reporting service, or if not so available, in such manner as furnished by any New York Stock Exchange member firm selected from time to time by the Board of Directors for that purpose, or a price determined in good faith by the Board of Directors or, to the extent permitted by applicable law, a duly authorized committee thereof, whose determination shall be conclusive. "CURRENT MARKET PRICE" shall mean the average of the daily Closing Prices per share of Class A Common Stock for the ten consecutive Trading Days immediately prior to the date in question; PROVIDED, HOWEVER, that (A) if the "ex" date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to this Section 8(e) occurs during such ten consecutive Trading Days, the Closing Price for each Trading Day prior to the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the fraction by which the Conversion Price is so required to be adjusted as a result of such other event, and (B) if the "ex" date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 8(e)(i), (ii), (iii), (iv) or (v) occurs on or after the "ex" date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event, and (C) if the "ex" date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (A) or (B) of this proviso, the Closing Price for each Trading Day on or after such "ex" date shall be adjusted by adding thereto the amount of any cash and the Fair Market Value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 8(e)(iv), (v) or (vi), whose determination shall be conclusive and described in a resolution of the Board of Directors) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Class A Common Stock as of the close of business on the day before such "ex" date. For purposes of any computation under Section 8(e)(vi), the Current Market Price of the Class A Common Stock on any date shall be deemed to be the average of the daily Closing Prices per share of Class A Common Stock for such day and the next two succeeding Trading Days; PROVIDED, however, that if the "ex" date for any event (other than the tender or exchange offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 8(e)(i), (ii), (iii), (iv), (v) or (vi) occurs on or after the Expiration Time or Tender Expiration Time, as the case may be, for the tender or exchange offer requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term "ex" date, (1) when used with respect to any A-12 <Page> issuance or distribution, means the first date on which the Class A Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution, (2) when used with respect to any subdivision or combination of shares of Class A Common Stock, means the first date on which the Class A Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and (3) when used with respect to any tender or exchange offer, means the first date on which the Class A Common Stock trades regular way on such exchange or in such market after the Expiration Time or Tender Expiration Time, as the case may be, of such offer. "FAIR MARKET VALUE" shall mean the amount which a willing buyer would pay a willing seller in an arm's length transaction. (viii) In any case in which this Section 8(e) shall require that an adjustment be made on a record date established for purposes of this Section 8(e), the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the certificate described in Section 4.09 of the Indenture) issuing to the Holder of any Note converted after such record date but prior to the issue date, the shares of Class A Common Stock and other capital stock of the Company issuable upon such conversion over and above the shares of Class A Common Stock and other capital stock of the Company issuable upon such conversion only on the basis of the Conversion Price prior to adjustment; and, in lieu of the shares the issuance of which is so deferred, the Company shall issue or cause its transfer agents to issue due bills or other appropriate evidence prepared by the Company of the right to receive such shares. If any distribution in respect of which an adjustment to the Conversion Price is required to be made as of the record date or effective date therefor is not thereafter made or paid by the Company for any reason, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect if such record date had not been fixed or such effective date had not occurred.
