-2-

For all purposes of this Warrant (other than this Section 2.1), any reference herein to the exercise of this Warrant shall be deemed to include a reference to the conversion of this Warrant into Class A Common Stock in accordance with the terms of this Section 2.1

2.2. When Exercise Effective. Each exercise or conversion of this Warrant shall be deemed to have been effected immediately prior to the close of business on the Business Day on which this Warrant shall have been surrendered to the Company as provided in Section 2.1 hereof, and at such time the Person or Persons in whose name or names any certificate or certificates for shares of Class A Common Stock shall be issuable upon such exercise as provided in Section 2.3 hereof shall be deemed to have become the Holder or Holders of record thereof.

2.3. Delivery of Stock Certificates, etc. As soon as practicable after each exercise of this Warrant, in whole or in part, and in any event within three Business Days thereafter, the Company at its expense (including the payment by it of any applicable issue taxes) will cause to be issued in the name of and delivered to the Holder hereof or as such Holder may direct:

3. ADJUSTMENT OF WARRANT PRICE AND CLASS A COMMON STOCK ISSUABLE UPON EXERCISE.

3.1. General; Number of Shares; Warrant Price. The number of shares of Class A Common Stock which the Holder of this Warrant shall be entitled to receive upon each exercise hereof shall be equal to the product of:

(a) the number of shares of Class A Common Stock which would otherwise (but for the provisions of this Section 3) be issuable upon such exercise, as designated by the Holder hereof pursuant to Section 2.1 hereof, and

-3-

(b) a fraction of which (i) the numerator is the Initial Warrant Price, and (ii) the denominator is the Warrant Price in effect on the date of such exercise.

The “Initial Warrant Price” shall be the Exercise Price. The “Warrant Price” shall initially be the Initial Warrant Price and shall be adjusted and readjusted from time to time as provided in this Section 3 and, as so adjusted or readjusted, shall remain in effect until a further adjustment or readjustment thereof is required by this Section 3. The “Trigger Price” shall initially be $167 per share of Class A Common Stock and shall be adjusted and readjusted from time to time as provided in this Section 3 and, as so adjusted and readjusted, shall remain in effect until a further adjustment or readjustment thereof is required by Section 3.

3.2. Adjustments for Dividends, Distributions, Stock Splits, etc.

(a) Dividends and Distributions. In case at any time or from time to time, the Holders of Class A Common Stock shall have received, or (on or after the record date fixed for the determination of shareholders eligible to receive) shall have become entitled to receive, without payment therefor:

(i) other or additional stock or Other Securities or property (other than cash) by way of dividend, or

(ii) any cash, or

(iii) other or additional stock or Other Securities or property (including cash) by way of spinoff, split-up, reclassification, recapitalization, combination of shares or similar corporate rearrangement, other than additional shares of Class A Common Stock issued as a stock dividend or in a stock split (adjustments in respect of which are provided for in Section 3.2(b) below),

then and in each such case the Holder of this Warrant, on the exercise hereof as provided in Section 2, shall be entitled without the payment of any additional consideration or the taking of any further action, to receive the amount of stock and Other Securities and property (including cash in the cases referred to in subdivisions (ii) and (iii) of this Section 3.2(a)) which such Holder would hold on the date of such exercise if on the date hereof such Holder had been the holder of record of the number of shares of Common Stock provided for herein and had thereafter, during the period from the date hereof to and including the date of such exercise, retained such shares and all such other or additional stock and Other Securities and property (including cash in the cases referred to in subdivisions (ii) and (iii) of this Section 3.2(a)) receivable by such Holder as aforesaid during such period, giving effect to all adjustments called for during such period by this Section 3.

(b) Treatment of Stock Dividends, Stock Splits, etc. In the event that the Company shall (i) issue Common Stock Equivalents, or securities exercisable for or convertible into Common Stock Equivalents, as dividend or other distribution on outstanding Common

-4-

Stock Equivalents, (ii) subdivide its outstanding shares of Common Stock Equivalents, or (iii) combine its outstanding shares of Common Stock Equivalents into a smaller number of shares of the Common Stock Equivalents, then, in each such event, the Warrant Price and the Trigger Price shall, simultaneously with the happening of such event, be adjusted by multiplying each of the then current Warrant Price and Trigger Price by a fraction, (a) the numerator of which shall be the number of shares of Common Stock Equivalents outstanding immediately prior to such event, and (b) the denominator of which shall be the number of shares of Common Stock Equivalents outstanding immediately after such event, and the product so obtained shall thereafter be the Warrant Price and the Trigger Price, respectively, then in effect. The Warrant Price and Trigger Price, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described herein in this Section 3.2. Upon each adjustment of the Warrant Price or Trigger Price, the Holder of this Warrant shall thereafter be entitled to purchase at the Warrant Price resulting from such adjustment, the number of shares obtained by dividing the product of the number of shares purchasable pursuant hereto immediately prior to such adjustment and the Warrant Price immediately preceding such adjustment by the Warrant Price resulting from such adjustment.

3.3. Reorganization, Consolidation or Merger. In case at any time or from time to time the Company shall (a) effect a reorganization, (b) consolidate with or merge into any other Person, (c) voluntarily or involuntarily dissolve, liquidate or wind-up, or (d) transfer all or substantially all of its properties or assets to any other Person, then in each such case, as a condition thereto, lawful and adequate provision shall be made so that the Holder of this Warrant, on the exercise or conversion hereof as provided in Section 2 at any time after the consummation of such reorganization, consolidation or merger or the effective date of such dissolution, as the case may be, shall receive, in lieu of the Class A Common Stock issuable on such exercise immediately prior to such consummation or such effective date, the stock and other securities and property (including cash) to which such Holder would have been entitled upon such consummation or in connection with such reorganization, consolidation, merger or dissolution, as the case may be, if such Holder had so exercised this Warrant, immediately prior thereto, all subject to further adjustments thereafter as provided in this Section 3.

3.4. Adjustment for Issuance of Common Stock Equivalents Below Trigger Price.

(a) General. In any case to which Sections 3.2 and 3.3 hereof are not applicable, where the Company shall issue or sell shares of its Common Stock Equivalents after February 1, 2001 without consideration or for a consideration (or evidencing a value of Common Stock Equivalents) per share less than the Warrant Price in effect pursuant to the terms of this Warrant at the time of issuance or sale of such additional shares, except where such shares are issued or sold pursuant to the exercise of any warrant or option or issued prior to the date of this Warrant or issued in connection with or pursuant to documentation entered into in connection with a financing by the Company in which the Company issues shares of Series A Redeemable Participating Preferred Stock, then the Warrant Price in effect hereunder shall simultaneously with such issuance or sale be reduced to a price determined by multiplying the Warrant Price then in effect hereunder by a fraction, the numerator of which is the sum of (a) the product of the total number of shares of Common Stock Equivalents outstanding immediately prior to such issuance or sale on a fully diluted basis, after giving effect to the exchange or conversion of all outstanding Convertible Securities and the exercise of all Options outstanding multiplied by the

-5-

Warrant Price in effect hereunder at the time of such issuance or sale, plus (b) the aggregate consideration received by the Company upon such issuance or sale, and the denominator of which is the product of the total number of shares of Common Stock Equivalents outstanding immediately after issuance or sale of such additional shares on a fully diluted basis, after giving effect to the exchange or conversion of all outstanding Convertible Securities and the exercise of all Options outstanding multiplied by the Warrant Price in effect hereunder at the time of such issuance.

(b) Options; Convertible Securities. In case the Company shall issue or sell any Options or Convertible Securities after December 16, 1999 there shall be determined the price per share for which Common Stock Equivalents are issuable upon the conversion or exercise thereof, such determination to be made by dividing (i) the sum of the total amount received or receivable by the Company as consideration for the issue or sale of such Options or Convertible Securities plus the minimum aggregate amount of additional consideration payable to the Company upon the conversion or exercise thereof, by (ii) the maximum number of shares of Common Stock Equivalents of the Company issuable upon the conversion or exercise of all of such Options or Convertible Securities. If the price per share so determined shall be less than the applicable Trigger Price, then, for purposes of Section 3.4(a) hereof, such issue or sale shall be deemed to be an issue or sale (as of the date of issue or sale of such Options or Convertible Securities) of such maximum number of shares of Common Stock Equivalents at the price per share so determined and such maximum number of shares shall be deemed to be outstanding after such issuance, provided that, upon the expiration of such rights of conversion or exercise of such Options or Convertible Securities, if any thereof shall not have been exercised, the adjusted Warrant Price shall forthwith be readjusted and thereafter be the price which it would have been had an adjustment been made on the basis that the only shares of Common Stock Equivalents so issued or sold were issued or sold upon the conversion or exercise of such Options or Convertible Securities, and that they were issued or sold for the consideration actually received by the Company upon such conversion or exchange, plus the consideration, if any, actually received by the Company for the issue or sale of all such Options or Convertible Securities which shall have been converted or exchanged.

(c) Record Date. If the Company takes a record of the holders of Common Stock Equivalents for the purpose of entitling them (1) to receive a dividend or other distribution payable in Common Stock Equivalents, Options or Convertible Securities, or (2) to subscribe for or purchase Common Stock Equivalents, Options or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock Equivalents deemed to have been issued or sold upon the declaration of such dividend or upon the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be.

(d) Termination Upon a Qualified Public Offering. This Section 3.4 shall terminate, and no adjustments under this Section 3.4 shall be required, upon the consummation of a Qualified Public Offering.

3.5. Minimum Adjustment of Warrant Price and Trigger Price. If the amount of any adjustment of the Warrant Price required pursuant to this Section 3 would be less than one-tenth

-6-

(1/10) of one percent (1%) of the Warrant Price or Trigger Price, as the case may be, in effect at the time such adjustment is otherwise so required to be made, such amount shall be carried forward and adjustment with respect thereto made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate at least one tenth (1/10) of one percent (1%) of such Warrant Price or Trigger Price.

3.6. Shares Deemed Outstanding. For all purposes of the computations to be made pursuant to this Section 3, treasury shares shall not be deemed to be outstanding.

3.7. Calculation of Consideration Received. If any Common Stock Equivalents, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor shall be deemed to be the amount received by the Company therefor (net of discounts, commissions and related expenses). If any Common Stock Equivalents, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company shall be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company shall be the Current Market Price thereof as of the date of receipt. For purposes of this Warrant, the fair value of any consideration other than cash and securities shall be determined by the board of directors of the Company using its good faith discretion.

3.8. Integrated Transactions. In case any Options are issued in connection with the issue or sale of Other Securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options shall be deemed to have been issued for a consideration of $1.00 (as adjusted consistent to give effect to the occurrences set forth in Sections 3.2 and 3.3).

4. NO IMPAIRMENT. The Company (a) will not permit the par value of any shares of stock receivable upon the exercise of this Warrant to exceed the amount payable therefor upon such exercise plus the amount deemed to have been paid upon issuance of this Warrant, (b) will take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of stock on the exercise of the Warrants from time to time outstanding, (c) will not take any action which results in any adjustment of the Warrant Price if the total number of shares of Class A Common Stock issuable after the action upon the exercise of all of the Warrants would exceed the total number of shares of Class A Common Stock then authorized by the Company’s certificate of incorporation and available for the purpose of issue upon such exercise.

5. REPORT AS TO ADJUSTMENTS. In each case of any adjustment or readjustment in the shares of Class A Common Stock issuable upon the exercise of (and the Warrant Price under) this Warrant, the Company at its expense will promptly compute such adjustment or readjustment in accordance with the terms of this Warrant and prepare a report setting forth such adjustment or readjustment and showing in reasonable detail the method of calculation thereof and the facts upon which such adjustment or readjustment is based, including a statement of (a) the number of shares of Class A Common Stock outstanding or deemed to be outstanding, and (b) the Warrant Price in effect immediately prior to such issue or sale and as adjusted and

-7-

readjusted (if required by Section 3 hereof) on account thereof. The Company will forthwith mail a copy of each such report to each Holder of a Warrant and will, upon the written request at any time of any Holder of a Warrant, furnish to such Holder a like report setting forth the Warrant Price and the Trigger Price at the time in effect and showing in reasonable detail how it was calculated. The Company will also keep copies of all such reports at its office maintained pursuant to Section 11.2(a) hereof and will cause the same to be available for inspection at such office during normal business hours by any Holder of a Warrant or any prospective purchaser of a Warrant designated by the Holder thereof.

6. NOTICES OF CORPORATE ACTION. In the event of:

(a) any taking by the Company of a record of the Holders of any class of securities for the purpose of determining the Holders thereof who are entitled to receive any dividend or other distribution, or any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any Other Securities or property, or to receive any other right, or

(b) the declaration by the Company of any dividend payable in stock upon Common Stock Equivalents or any other distribution by the Company to the holders of the Common Stock Equivalents, or

(c) the Company proposing to make an offer for subscription pro rata to the holders of its Common Stock Equivalents of any additional shares of stock of any class or other rights, or

(d) any capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company or any consolidation or merger involving the Company and any other Person or any transfer of all or substantially all the assets of the Company to any other Person, or

(e) any voluntary or involuntary dissolution, liquidation or winding-up of the Company, or

(f) any other action of a type referred to in Section 3 hereof, the Company shall mail to each Holder of a Warrant a notice specifying (i) the date or expected date on which any such record is to be taken for the purpose of such dividend, distribution or right, and the amount and character of such dividend, distribution or right, and (ii) the date or expected date on which any such reorganization, reclassification, recapitalization, consolidation, merger, transfer, dissolution, liquidation or winding-up is to take place, the time, if any such time is to be fixed, as of which the Holders of record of Class A Common Stock shall be entitled to exchange their shares of Class A Common Stock for the securities or other property deliverable upon such reorganization, reclassification, recapitalization, consolidation, merger, transfer, dissolution, liquidation or winding-up and a description in reasonable detail of the transaction. Such notice shall be mailed at least 45 days prior to the date therein specified. At no time prior to the date therein specified shall the Company take any action which could prevent the exercise or conversion of this Warrant in accordance with the terms hereof.

7. REGISTRATION OF WARRANTS AND COMMON STOCK. If any shares of Class A Common Stock required to be reserved for purposes of exercise of this Warrant require

-8-

registration with or approval of any governmental authority under any federal or state law (including without limitation the Hart-Scott-Rodino Antitrust Improvements Act of 1976) before such shares may be issued upon exercise, the Company shall, at its expense and as expeditiously as possible, use its best efforts to cause such shares to be duly registered or approved, as the case may be. The shares of Class A Common Stock (and Other Securities) issuable upon exercise of this Warrant shall constitute Registrable Shares (as such term is defined in the Registration Rights Agreement). Each Holder of this Warrant shall be entitled to all of the benefits afforded to a Holder of any such Registrable Shares under the Registration Rights Agreement. At any such time as the Class A Common Stock is listed on any national securities exchange or quotation system, the Company shall, at its expense, obtain promptly and maintain the approval for listing on each such exchange or system, upon official notice of issuance, the shares of Class A Common Stock issuable upon exercise of the then outstanding Warrants and will use its best efforts to maintain the listing of such shares after their issuance at all times when the Class A Common Stock is so listed.

8. REORGANIZATION, CONSOLIDATION, MERGER, ETC. In case the Company after December 16, 1999 shall (a) effect a reorganization, (b) consolidate with or merge with or into any other entity, or (c) transfer all or substantially all of its properties or assets to any other person or entity, then, in each such case, the Holder of this Warrant, upon the exercise hereof as provided in Section 2 at any time after the consummation of such reorganization, consolidation, merger or transfer, as the case may be, shall be entitled to receive, in lieu of the Class A Common Stock (or Other Securities) issuable upon such exercise prior to such consummation, the stock and Other Securities and property (including cash) to which such Holder would have been entitled upon such consummation if such Holder had so exercised this Warrant immediately prior thereto, all subject to further adjustment thereafter as provided in Section 3 hereof. The Company shall not consummate any such reorganization, consolidation, merger or transfer, unless the resulting, surviving or transferee entity, as the case may be, expressly agrees in writing, reasonably satisfactory to the Holders of a majority of the Warrants then outstanding, to fulfill the Company’s obligations under this Warrant and this Section 8.

9. PERFORMANCE OF OBLIGATIONS. The Company shall not, by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation, merger, issue or sale of securities or otherwise, avoid or take any action which would have the effect of avoiding the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in carrying out all of the provisions of this Warrant and in taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder of this Warrant against dilution or other impairment to the extent set forth in this Warrant.

10. RESERVATION OF STOCK, ETC. The Company shall at all times reserve and keep available, solely for issuance and delivery upon exercise of the Warrants, the number of shares of Class A Common Stock of each class from time to time issuable upon exercise of all Warrants at the time outstanding. All shares of Class A Common Stock issuable upon exercise of any Warrants shall be duly authorized and, when issued upon such exercise, shall be validly issued, fully paid and nonassessable.

11.3. Replacement of Warrants. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of any Warrant and, in the case of any such loss, theft or destruction of any Warrant held by a Person other than a purchaser or any institutional investor, upon delivery of indemnity reasonably satisfactory to the Company in form and amount or, in the case of any such mutilation, upon surrender of such Warrant for cancellation at the office of the Company maintained pursuant to Section 11.2(a) hereof, the Company at its expense will execute and deliver, in lieu thereof, a new Warrant of like tenor and dated the date hereof.
