Instead of any fractional shares of Class A Common Stock of the Corporation which would otherwise be issuable upon conversion of any shares of Class B Common Stock, the Corporation shall pay a cash adjustment in respect of such fractional interest in the amount equal to the product obtained by multiplying such fraction by the Market Price of the Class A Common Stock on the Business Day immediately prior to conversion.

The Corporation shall deliver, as soon as practicable after receipt of such notice and certificates, at said office, to or on the order of the holder for whose account such certificates for shares of Class B Common Stock were so surrendered for conversion, a certificate or certificates representing that number of whole shares of Class A Common Stock which the holder of such shares of Class B Common Stock shall be entitled to receive, registered in the name of such Person or Persons as may be specified in the notice of conversion, together with payment of any cash adjustment to which such holder may be entitled in accordance with clause (e) of this Section 4(C)2. Any conversion of shares of Class B Common Stock at the option of the holder thereof shall be deemed for all purposes to have been effected upon delivery of such notice of conversion and such surrender of the certificate or certificates for shares of Class B Common Stock to be so converted; PROVIDED, HOWEVER, that any such surrender on any date when the stock transfer books of the Corporation shall be closed shall not be deemed to constitute the Person or Persons in whose name or names the certificates of Common Stock are to be registered as the holder or holders thereof for any purpose until the close of business on the next succeeding day on which such stock transfer books shall be open but such conversion shall be made at the conversion ratio in effect on the date of such surrender.

For purposes of this Section 4(C)2, subject to Section 5, a written statement of the Person converting shares of Class B Common Stock into Class A Common Stock, delivered to the Corporation upon surrender of any shares of Class B Common Stock for conversion into any shares of Class A Common Stock, to the effect that the Person is legally entitled to exercise its rights to convert such shares and that such conversion will not violate the prohibitions set forth in the preceding sentence, shall be conclusive and binding upon the Corporation and shall obligate the Corporation to deliver certificates representing the shares of Class A Common Stock so converted in accordance with the other provisions hereof.

Without limitation of the foregoing and subject to the provisions of Section 4(D)2(b) below, in a LSA Event, (i) each Holder of Series D Preferred Stock shall be entitled to receive out of the assets of the Corporation available for distribution to stockholders, before any distribution of assets shall be made to the holders of the Series C Preferred Stock, Junior Preferred Stock or Junior Securities or any other stock of the Corporation, an amount in cash (PROVIDED, that such Holder does not elect to convert its shares pursuant to its rights in Section 4(D)3) for each share equal to the greater of (x) the Series D Liquidation Preference plus all accrued and unpaid dividends for each share of Series D Preferred Stock, or (y) the amount such Holder would receive as a holder of Common Stock if the Series D Preferred Stock held by such Holder was converted into Common Stock, assuming the conversion into Common Stock of all the Preferred Stock, (ii) after payment in full has been made in accordance with this Section 4(D)2 to all Holders of shares of Series D Preferred Stock, each Holder of the Series C Preferred Stock shall be entitled to receive out of the assets of the Corporation available for distribution to stockholders, before any distribution of assets shall be made to the holders of the Junior Preferred Stock or Junior Securities or any other stock of the Corporation ranking junior to Series C Preferred Stock as to any such distribution, an amount in cash (PROVIDED, that such Holder does not elect to convert its shares pursuant to its rights in Section 4(D)3) for each share equal to the greater of (x) the Series C Liquidation Preference or (y) the amount such Holder would receive as a holder of Common Stock if the Series C Preferred Stock held by such Holder was converted into Common Stock, assuming the conversion into Common Stock of all the Preferred Stock, and (iii) after payment in full has been made in accordance with this Section 4(D)2 to all Holders of shares of Series D Preferred Stock and Series C Preferred Stock, each Holder of the Junior Preferred Stock, without distinction as to series, shall be entitled to receive out of the assets of the Corporation available for distribution to stockholders, before any distribution of assets shall be made to the holders of the Junior Securities or any other stock of the Corporation ranking junior to Junior Preferred Stock as to any such distribution, an amount in cash (PROVIDED, that such Holder does not elect to convert its shares pursuant to its rights in Section 4(D)3) for each share equal to the Junior Preferred Liquidation Preference. If, upon a LSA Event, the amounts payable with respect to any series of Preferred Stock and any other stock of the Corporation ranking as to any such distribution on a parity with such series of Preferred Stock shall not be paid in full, then the Holders of such series of Preferred Stock and such parity stock shall share ratably in any such distribution of assets of the Corporation in proportion to the full preferential amounts to which they are entitled. (b) DISTRIBUTION OF REMAINDER IN LIQUIDATION. In the event of a Liquidation, in addition to the distributions set forth in Section 4(D)2(a) and after payment in full of all amounts payable to the Holders of Preferred Stock under Section 4(D)2(a), (i) the holders of Common Stock shall be entitled to participate in the distribution of the remainder of the assets of the Corporation in respect of the Common Stock until each such holder has received an amount per share equivalent to the amount per share received by the Holders of Preferred Stock, considered on an as-if-converted basis (calculated by dividing (x) the aggregate distributions made to all Holders of Preferred Stock in accordance with Section 4(D)2(a) by (y) the total number of Common Stock into which the Preferred Stock could be converted), and (ii) thereafter, the Holders of Preferred Stock shall be entitled to participate with the holders of Common Stock, on an as-if-converted basis, in the distribution of any remaining assets of the Corporation in respect of the Common Stock. (c) REDEMPTION IN SALE TRANSACTION OR ASSET SALE. In connection with any Sale Transaction or Asset Sale, all consideration payable to the stockholders of the Corporation, in connection with a Sale Transaction, or all consideration payable to the Corporation, together with all other available assets of the Corporation (net of obligations owed by the Corporation), in the case of an Asset Sale, shall be paid to and deemed (to the fullest extent permitted by law) distributed (in the case of a Sale Transaction) or available for distribution and payment as provided herein (in the case of an Asset Sale), as applicable, to the holders of Preferred Stock of the Corporation in accordance with the preferences and priorities set forth in Section 4(D)2(a) above. In the event of a Sale Transaction, the Corporation shall cause the Sale Transaction agreement to provide as a consequence of such -10- <Page> Sale Transaction for the conversion of (i) any outstanding Series D Preferred Stock into the right of each Holder of Series D Preferred Stock to receive an amount in cash equal to the amount set forth in Section 4(D)2(a)(i), (ii) any outstanding Series C Preferred Stock into the right of each Holder of Series C Preferred Stock to receive, subject to the prior satisfaction, in accordance with the provisions of this Section 4(D)2, of the Holders of Series D Preferred Stock, an amount in cash equal to the amount set forth in Section 4(D)2(a)(ii), and (iii) any outstanding Junior Preferred Stock into the right of each Holder of Junior Preferred Stock to receive, subject to the prior satisfaction, in accordance with the provisions of this Section 4(D)2, of the Holders of Series D Preferred Stock and Series C Preferred Stock, an amount in cash equal to the amount set forth in Section 4(D)2(a)(iii). In the event of an Asset Sale, immediately concurrent with the consummation of such Asset Sale, the Corporation shall cause the redemption of all outstanding shares of Preferred Stock for an amount (in cash) equal to the applicable amount payable under Section 4(D)2(a). In the event of the foregoing redemption, (i) the Corporation shall revalue its assets and liabilities to the fullest extent permitted by law to determine lawfully available funds for such redemption, and (ii) if the Corporation shall not have such funds available to redeem the shares of all series of Preferred Stock, the Corporation shall redeem, to the fullest extent of available funds as the same became available, the shares of each series of Preferred Stock in accordance with the preferences and priorities set forth in Section 4(D)2(a). (d) NOTICE OF REDEMPTION. Any redemption of the Preferred Stock pursuant to Section 4(D)2(c) hereof may be made only if prior notice is given by the Corporation at least 30 days but not more than 60 days prior to the date fixed for such redemption (a "REDEMPTION DATE") to all Holders of record of each series of Preferred Stock at their respective addresses appearing on the books of the Corporation. Any such notice of a redemption shall specify (i) the details of the transaction in connection with which such shares of Preferred Stock are being redeemed, (ii) the Redemption Date, (iii) the redemption price applicable to each series of Preferred Stock (as determined in accordance with the provisions of Section 4(D)2(a)), and (iv) each Holder's right to convert the shares of Preferred Stock held by such Holder into Common Stock in accordance with the provisions of Section 4(D)3 hereof by notifying the Corporation in writing prior to the Redemption Date. From and after the date fixed in such notice as the Redemption Date, to the extent a Holder did not elect to convert the shares of Preferred Stock held by such Holder (and unless default shall have been made by the Corporation in providing monies for the payment in full of the redemption price), all rights of such Holder of Preferred Stock as stockholder of the Corporation (except the right to receive payment in full of the redemption price) shall cease. (e) SHARES RETIRED. All shares of the Preferred Stock redeemed by the Corporation shall be retired and cancelled and shall not be reissued. 3. CONVERSION OF PREFERRED STOCK. (a) RIGHT TO CONVERT. Each Holder of Preferred Stock shall have the right, at any time (subject to the Corporation obtaining the requisite government approvals referred to in Section 5), to convert all or any portion of such Holder's shares of Preferred Stock into such number of validly issued fully paid and nonassessable shares of Class A Common Stock or, if required by applicable law, Class B Common Stock ("CONVERSION STOCK"), as is equal to the quotient obtained by dividing (A) the Liquidation Preference of the shares of Preferred Stock being converted, by (B) the applicable Conversion Price (as last adjusted and then in effect) for the shares of Preferred Stock being converted, by surrender of the certificates representing the shares of Preferred Stock to be converted in the manner provided for in Section 4(D)3(b) hereof. As of the Effective Time, the initial conversion price (the "CONVERSION PRICE") shall be, (i) as to shares of Junior Preferred Stock, $125.00 per share of Common Stock, (ii) as to shares of Series C Preferred Stock, $150.00 per share of Common Stock, and (iii) as to shares of Series D Preferred Stock, $80.00 per share of Common Stock, and each price shall be subject to adjustment as provided for in Section 4(D)4 hereof. Any accrued but unpaid dividends on any shares of Series C Preferred Stock or Junior Preferred Stock converted in accordance with the provisions of this Section 4(D)3 form part of the Liquidation Preference of such Preferred Stock and shall be converted into Conversion Stock as set forth in this Section 4(D)3. The Holders of Series D Preferred Stock shall not be entitled to payment in cash or stock of any accrued but unpaid dividends in the event of any conversion under this Section 4(D)3. (b) EXERCISE OF CONVERSION RIGHT. The Holder of any shares of Preferred Stock may exercise the conversion right pursuant to Section 4(D)3(a) hereof by delivering to the Corporation during regular business -11- <Page> hours, at the office of any transfer agent of the Corporation for the Preferred Stock, or at such other place as may be designated by the Corporation, the certificate or certificates for the shares to be converted, duly endorsed or assigned in blank to the Corporation, accompanied by written notice (a "CONVERSION NOTICE") stating that such Holder elects to convert such shares and stating the name or names (with address) in which the certificate or certificates for the shares of Conversion Stock are to be issued and the class or classes of Conversion Stock to be issued; PROVIDED, HOWEVER, that, if such name or names are other than that of the Holder, such issuance of Conversion Stock is permitted by applicable Federal and state securities laws. On a date (the "CONVERSION DATE") to be scheduled as promptly as possible, but in any event within ten Business Days thereafter, the Corporation shall issue and deliver to the Holder, or upon the written order of such Holder, to the Person and place designated by such Holder, (i) a certificate or certificates for the number of full shares of Conversion Stock to which such Holder is entitled and (ii) a check or cash in respect of any fractional interest in a share of Common Stock, as provided for in Section 4(D)3(d) hereof, payable with respect to the shares of Preferred Stock so converted up to and including the Conversion Date. The Person in whose names the certificate or certificates for Conversion Stock are to be issued shall be deemed to have become a stockholder of record on the next succeeding date on which the transfer books are open, but the Conversion Price shall be that in effect on the Conversion Date. Upon conversion of only a portion of the number of shares covered by a certificate representing shares of Preferred Stock surrendered for conversion, the Corporation shall issue and deliver to or upon the written order of the Holder of the certificate so surrendered for conversion, at the expense of the Corporation, a new certificate covering the number of shares of Preferred Stock representing the unconverted portion of the certificate so surrendered, which new certificate shall entitle the Holder thereof to declared but unpaid dividends, if any, on the shares of Preferred Stock represented thereby to the same extent as if the certificate therefor covering such unconverted shares had not been surrendered for conversion. Notwithstanding the foregoing, any Holder exercising the right to convert granted under this Section 4(D)3 in contemplation of a Public Offering, Sale Transaction or Asset Sale or any other transaction or event shall have the right to make such conversion contingent upon the consummation of such transaction or event by so specifying in the relevant Conversion Notice. Any contingent conversion shall be irrevocably effective on the date the applicable transaction or event is consummated or occurs, and may be revoked by the Holder at any time prior to such consummation or if the applicable Public Offering, Sale Transaction or Asset Sale is abandoned. (c) CONVERSION OF PREFERRED STOCK UPON PUBLIC OFFERING. Upon the consummation of a Public Offering, the Corporation shall have the right (but not the obligation) to require all Holders of Preferred Stock to convert their shares of Preferred Stock into such number of validly issued fully paid and nonassessable shares of Class A Common Stock or, if required by applicable law, Class B Common Stock, as is equal to the quotient obtained by dividing (A) the applicable Liquidation Preference of the shares of Preferred Stock being converted, by (B) the respective Conversion Price (as last adjusted and then in effect) for such Preferred Stock; PROVIDED, HOWEVER, that the Corporation's right to require the Holders of Series C Preferred Stock or Series D Preferred Stock to convert their shares of Preferred Stock shall be subject to the satisfaction of the Mandatory Conversion Condition applicable to the Series C Preferred Stock and the Series D Preferred Stock, respectively. The mandatory conversion condition (the "MANDATORY CONVERSION CONDITION") shall be satisfied if the Calculated IRR on the original purchase price of each share of Series C Preferred Stock and Series D Preferred Stock, respectively, assuming a conversion into shares of Common Stock at the respective Conversion Price for the Series C Preferred Stock and the Series D Preferred Stock then in effect, in each case, with a value on such Common Stock at the price at which shares of Common Stock are sold to the public in the Public Offering giving rise to the need to calculate the Calculated IRR, shall be equal to or greater than 25%. (d) NO FRACTIONAL SHARES. No fractional shares of Conversion Stock or scrip shall be issued upon conversion of shares of Preferred Stock. If more than one share of Preferred Stock shall be surrendered for conversion at any one time by the same Holder, the number of full shares of Conversion Stock issuable upon conversion thereof shall be computed using the aggregate number of shares of Preferred Stock so surrendered. Instead of issuing any fractional shares of Conversion Stock that would otherwise be issuable upon conversion of any shares of Preferred Stock, the Corporation shall make payment to such Holder, in cash, of an amount equal to the fraction of a share of Conversion Stock otherwise issuable to such Holder, multiplied by the Market Price on the Business Day immediately prior to conversion. -12- <Page> (e) STAMP AND OTHER TAXES. The Corporation shall pay all documentary, stamp or other transactional taxes attributable to the issuance or delivery of shares of Capital Stock of the Corporation upon conversion of any shares of Preferred Stock; PROVIDED, HOWEVER, that the Corporation shall not be required to pay any taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificate of such shares in a name other than that of the Holder of the shares of Preferred Stock in respect of which such shares are being issued. (f) RESERVATION OF COMMON STOCK. The Corporation shall reserve, free from preemptive rights, out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of Preferred Stock (assuming a Conversion Price of $80.00, as such amount is adjusted from time to time as contemplated by Section 4(D)4 hereof and the conversion, exercise and exchange of all other outstanding Convertible Securities and Options) a sufficient number of shares of each of Class A Common Stock and Class B Common Stock so as to provide for the conversion of all outstanding shares of Preferred Stock and all other outstanding Convertible Securities and Options into each of such applicable classes of Common Stock. The Corporation shall take all such actions as may be necessary to assure that all such shares of Common Stock may be so issued without violation of any applicable law or governmental regulation or any requirements of any domestic securities exchange upon which shares of Common Stock may be listed (except for official notice of issuance which shall be immediately delivered by the Corporation upon each such issuance). The Corporation shall not take any action which would cause the number of authorized but unissued shares of Common Stock to be less than the number of such shares required to be reserved hereunder for issuance upon conversion of the Preferred Stock. (g) NO LIENS. All shares of Conversion Stock which may be issued in connection with the conversion provisions set forth herein will, upon issuance by the Corporation, be validly issued, fully paid and nonassessable and free from all taxes, liens or charges with respect thereto created or imposed by the Corporation. 4. ADJUSTMENT OF CONVERSION PRICE, NUMBER OF SHARES OF COMMON STOCK, ETC. The applicable Conversion Price for the Preferred Stock shall be subject to adjustment from time to time as hereinafter provided for in this Section 4(D)4. (a) ADJUSTMENT UPON TRIGGERING EVENT. If a Triggering Event shall occur and the Calculated IRR with respect to either the Series A Preferred Stock or the Series B Preferred Stock, measured from their respective Original Issue Dates to the date of such Triggering Event, shall be less than 25%, the Conversion Price as to any such series in effect shall be reduced, but not increased, effective as of the date of such Triggering Event, to the higher of (i) $80.00 (as such price may be adjusted to reflect any event described in this Section 4(D)4 which becomes effective after the date hereof), or (ii) such price per share that, after giving effect to such reduction, the Calculated IRR in respect of the Series A Preferred Stock or Series B Preferred Stock, as the case may be, shall equal twenty-five percent (25%). (b) STOCK DIVIDENDS. In case at any time the Corporation shall declare a dividend or make any other distribution upon the Common Stock of the Corporation which is payable in Common Stock or Convertible Securities, each Conversion Price in effect immediately prior to such dividend or other distribution shall be proportionately reduced and the number of shares of Common Stock issuable upon conversion of each series of Preferred Stock immediately prior to such dividend or other distribution shall be proportionately increased. (c) SUBDIVISION OR COMBINATION OF STOCK. In case the Corporation shall at any time subdivide the outstanding shares of Common Stock into a greater number of shares, each Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced and the number of shares issuable upon conversion of each series of Preferred Stock immediately prior to such subdivision shall be proportionately increased, and conversely, in case the outstanding shares of Common Stock shall be combined at any time into a smaller number of shares, each Conversion Price in effect immediately prior to such combination shall be proportionately increased and the number of shares issuable upon conversion of each series of Preferred Stock immediately prior to such combination shall be proportionately reduced. -13- <Page> (d) ADJUSTMENTS FOR CONSOLIDATION, MERGER, REORGANIZATION, ETC. In case the Corporation (i) consolidates with or merges into any other corporation and is not the continuing or surviving corporation of such consolidation or merger and such consolidation or merger does not constitute a Sale Transaction, or (ii) permits any other corporation to consolidate with or merge into the Corporation and the Corporation is the continuing or surviving corporation but, in connection with such consolidation or merger, the Common Stock is changed into or exchanged for stock or other securities of any other corporation or cash or any other assets and such consolidation or merger does not constitute a Sale Transaction, or (iii) effects a capital reorganization or reclassification of the Capital Stock of the Corporation in such a way that holders of Common Stock shall be entitled to receive stock, securities, cash or assets with respect to or in exchange for Common Stock and such reorganization or reclassification does not constitute a Sale Transaction, then, and in each such case, proper provision, in form and substance reasonably satisfactory to the Holders of 75% of all Preferred Stock then outstanding (measured by the aggregate Liquidation Preference), shall be made so that, (i) upon the basis and upon the terms and in the manner provided for in this Section 4(D)4(d), upon the conversion of the Preferred Stock at any time after the consummation of such consolidation, merger, reorganization or reclassification, each Holder shall be entitled to receive (at the Conversion Price in effect for shares issuable upon such conversion of each respective series of Preferred Stock immediately prior to such consummation), in lieu of shares issuable upon such conversion of the Preferred Stock prior to such consummation, the stock and other securities, cash and assets to which such Holder would have been entitled upon such consummation if such Holder had so converted such Preferred Stock immediately prior thereto (subject to adjustments subsequent to such corporate action as nearly equivalent as possible to the adjustments provided for in this Section 4(D)4) and (ii) the provisions of this Section 4 thereafter shall remain applicable to the Preferred Stock (including, in the case of any such consolidation or merger in which the successor entity is other than the Corporation, an immediate adjustment of each Conversion Price to the value for the Common Stock reflected by the terms of such consolidation or merger, and a corresponding immediate adjustment in the number of shares of Conversion Stock acquirable and receivable upon conversion of each series of Preferred Stock, if the value so reflected is less than any Conversion Price which otherwise would be in effect immediately after such consolidation or merger). The Corporation shall not effect any such consolidation or merger, unless prior to the consummation thereof, the successor entity (if other than the Corporation) resulting from consolidation or merger assumes by written instrument (in form and substance satisfactory to the Holders of 75% of each class or series of the Preferred Stock then outstanding), the obligation to deliver to each such Holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such Holder may be entitled to acquire. (e) NOTICE OF ADJUSTMENT. Whenever the number of shares issuable upon the conversion of any series of Preferred Stock or any Conversion Price is adjusted, as provided for in this Section 4(D)4, the Corporation shall prepare and mail to each Holder a certificate setting forth (i) each Conversion Price and the number of shares issuable upon the conversion of each series of Preferred Stock after such adjustment, (ii) a brief statement of the facts requiring such adjustment and (iii) the computation by which such adjustment was made. (f) TREASURY SHARES. The number of shares of Common Stock outstanding at any given time shall not include shares of Common Stock owned or held by or for the account of the Corporation. The disposition of any shares of Common Stock owned or held by or for the account of the Corporation shall be considered an issue of Common Stock for the purposes of this Section 4(D)4. (g) CERTAIN ADJUSTMENT RULES. (i) The provisions of this Section 4(D)4 shall similarly apply to successive transactions. (ii) If the Corporation shall declare any dividend referred to in Section 4(D)4(b) hereof and if any Holder converts all or any part of the Preferred Stock after such declaration, but before the payment of such dividend, the Corporation may elect to defer, until the payment of such dividend, issuing to such Holder the shares of Common Stock issuable upon such conversion over and above the shares issuable upon such conversion on the basis of the applicable Conversion Price in effect prior to such adjustment; PROVIDED, HOWEVER, that the Corporation shall deliver to each such Holder a due bill or other appropriate instrument evidencing such Holder's right to receive such additional shares upon the payment of such dividend. -14- <Page> (iii) If the Corporation shall declare any dividend referred to in Section 4(D)4(b) hereof and shall legally abandon such dividend prior to payment, then no adjustment shall be made pursuant to this Section 4(D)4 in respect of such declaration. 5. VOTING RIGHTS. (a) Subject to Section 4(D)5(b) hereof and, with respect to the Holders of Preferred Stock that are limited in their ability to possess voting rights by certain regulatory requirements applicable to such Holders, subject to compliance with such requirements, the Holders of Preferred Stock shall be entitled to vote separately as a class on each matter required to be submitted to a vote of common stockholders under the Certificate of Incorporation of the Corporation or Delaware law; PROVIDED, HOWEVER, that, in respect of the election of the members of the board of directors of the Corporation, (i) the Holders of Series C Preferred Stock and Junior Preferred Stock shall vote together with the holders of Class A Common Stock and not separately as a class (with each share of Series C Preferred Stock, Junior Preferred Stock and Class A Common Stock having one vote) and (ii) the Holders of Series D Preferred Stock shall have no right to vote. (b) As long as any of the Preferred Stock shall be issued and outstanding, the Corporation shall not, without first obtaining the approval (by vote or by written consent as provided by law) of TC Carting L.L.C., TC Carting II, L.L.C. and Thayer Equity Investors IV, L.P., and the Holders, including TC Carting, L.L.C., TC Carting II, L.L.C. and Thayer Equity Investors IV, L.P., of not less than 75% of the aggregate Liquidation Preference of the shares of Preferred Stock then outstanding: (i) amend or repeal any provision of, or add any provision to, the Corporation's Certificate of Incorporation or By-Laws if such action would alter or change the preferences, rights, privileges or powers of, or the restrictions provided for the benefit of, the Preferred Stock; (ii) authorize or issue any additional shares of Preferred Stock except as a dividend on outstanding shares of Preferred Stock; (iii) authorize, create or issue any Capital Stock having any rights, preferences or priorities (including, without limitation, dividend or liquidation preferences) (A) senior to the Preferred Stock, or (B) on a parity with those of the Preferred Stock, or authorize, create or issue any bonds, debentures, notes or other obligations convertible into or exchangeable for, or having option rights to purchase, any shares of Capital Stock of the Corporation having any rights, preferences or priorities (including, without limitation, dividend or liquidation preferences) senior to or on a parity with the Preferred Stock; or (iv) reclassify any outstanding shares into shares having any rights, preferences or priorities (including, without limitation, dividend or liquidation preferences) (A) senior to the Preferred Stock, or (B) on a parity with those of the Preferred Stock. 6. TRANSFERABILITY. The shares of Preferred Stock shall not be transferable to any Person except in accordance with the Securities Act of 1933, as amended, and applicable state or "blue sky" laws, or an exemption therefrom. Each certificate representing shares of Preferred Stock shall include a legend in substantially the following form: "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY STATE SECURITIES LAWS AND MAY NOT BE OFFERED, SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF OR PLEDGED OR HYPOTHECATED UNLESS REGISTERED UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS OR UNLESS AN EXEMPTION FROM REGISTRATION UNDER THE ACT AND ANY SUCH LAWS IS AVAILABLE (AND, IN SUCH CASE, AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY, IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE COMPANY, SHALL HAVE BEEN DELIVERED TO THE COMPANY TO THE EFFECT THAT THE OFFER, SALE, -15- <Page> TRANSFER, DISPOSITION, PLEDGE OR HYPOTHECATION THEREOF IS EXEMPT FROM REGISTRATION UNDER THE ACT AND ANY SUCH LAWS).

Section 8. Unless, and except to the extent that, the by-laws of the Corporation (the "BY-LAWS") so require, the election of directors need not be by written ballot. -17- <Page> Section 9. The board of directors of the Corporation may from time to time adopt, amend or repeal the By-Laws, subject to the power of the stockholders to adopt any By-Laws or to amend or repeal any By-Laws adopted, amended or repealed by the board of directors. Section 10. To the fullest extent that the Delaware General Corporation Law as it exists on the date hereof, or as it may hereafter be amended, permits the limitation or elimination of the liability of directors, no director will be liable to the Corporation or its stockholders for monetary damage for breach of fiduciary duty as a director. Any repeal or amendment of this Section 10 will not adversely affect any limitation on the personal liability or alleged liability of a director arising from an act or omission of that director occurring prior to the time of such repeal or amendment. Section 11. No contract or transaction between the Corporation and one or more of its directors or officers, or between the Corporation and any other corporation, partnership, association, or other organization in which one or more of its directors or officers, are directors or officers, or have a financial interest, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the board of directors or committee which authorizes the contract or transaction, or solely because his or their votes are counted for such purpose, if: (A) The material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the board of directors or the committee, and the board of directors or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; or (B) The material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the stockholders; or (C) The contract or transaction is fair as to the Corporation as of the time it is authorized, approved or ratified by the board of directors, a committee or the stockholders. Common or interested directors may be counted in determining the presence of a quorum at a meeting of the board of directors or of a committee which authorizes the contract or transaction. -18- <Page> IN WITNESS WHEREOF, the undersigned has executed this Fourth Amended and Restated Certificate of Incorporation this 10th day of September, 2001.
