Section 4. Dividends. The holders of Class A-1 Preferred Shares shall be entitled to receive cumulative dividends at the rate of 5% of Liquidation Value in preference to the payment of dividends on any Junior Securities, when, as, and if declared by the Board.

The date on which any share of Class A-1 Preferred Shares is initially issued by the Corporation (or its predecessor) shall be deemed to be its “date of issuance” regardless of the number of times transfer of such share is made on the stock records maintained by or for the Corporation and regardless of the number of certificates which may be issued to evidence such share. Each certificate shall have a legend indicating the “date of issuance” for purposes of the dividend calculation referred to herein. Except as otherwise provided herein, if at any time the Corporation pays less than the total amount of dividends then accrued with respect to the Class A Preferred Shares, such payment shall be distributed pro rata among the holders thereof based upon the number of Class A Preferred Shares held by each such holder.

Section 5. Liquidation. Upon any liquidation, dissolution or winding up of the Corporation (whether voluntary or involuntary), each holder of Class A-1 Preferred Shares shall be entitled to be paid, before any distribution or payment is made upon any Junior Securities, an amount equal to the greater of (i) the aggregate Liquidation Value of all Class A-1 Preferred Shares (plus all accrued and unpaid dividends thereon) held by such holder or (ii) the amount such holder of Class A-1 Preferred Shares would be entitled to receive if all Class A Preferred Shares were converted into Common Stock (the “Liquidation Amount”). All holders of Class A Preferred Shares shall be pari passu with respect to their entitlement to receive their respective Liquidation Amounts. If upon any such liquidation, dissolution or winding up of the Corporation, the Corporation’s assets to be distributed among the holders of the Class A Preferred Shares are insufficient to permit payment to such holders of the aggregate amount which they are entitled to be paid, then the entire assets available to be distributed to the Corporation’s Class A Preferred Shares stockholders shall be distributed pro rata among such holders based upon the aggregate Liquidation Amount of the Class A Preferred Shares held by each such holder. Prior to the liquidation, dissolution or winding up of the Corporation, the Corporation shall declare for payment all accrued and unpaid dividends with respect to the Class A Preferred Shares, but only to the extent of funds of the Corporation legally available for the payment of dividends. Not less than sixty (60) days prior to the payment date stated therein, the Corporation shall mail written notice of any such liquidation, dissolution or winding up to each record holder of Class A Preferred Shares, setting forth in reasonable detail the amount of proceeds to be paid with respect to each Class A Preferred Share and each share of Common Stock in connection with such liquidation, dissolution or winding up.

Section 7. Special Voting Rights. The consent of the holders of at least two-thirds of the Class A-1 Preferred Shares, voting together as a single class, shall be required for any action that (a) authorizes or issues shares of any class of stock having any preference or priority superior to any preference or priority of the Class A-1 Preferred Shares (which shall not include the authorization or issuance of any Subsequent Class A Shares) or (b) changes the number of shares or class of stock into which the Class A-1 Preferred Shares is convertible.

Section 8. Conversion.

(a) Conversion Procedure.

(i) At any time and from time to time, any holder of Class A-1 Preferred Shares may convert all or any portion of the Class A-1 Preferred Shares held by such holder into 1.8 shares of Common Stock per each share of Class A-1 Preferred Shares (which gives effect to the 0.8 for one stock dividend declared on the Common Stock on February 23, 2001).

(ii) Except as otherwise provided herein, each conversion of Class A-1 Preferred Shares shall be deemed to have been effected as of the close of business on the date on which the certificate or certificates representing the Class A-1 Preferred Shares to be converted have been surrendered for conversion at the principal office of the Corporation. At the time any such conversion has been effected, the rights of the holder of the shares converted as a holder of Class A-1 Preferred Shares shall cease and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the shares of Common Stock represented thereby.

(iii) Notwithstanding any other provision hereof, if a conversion of Class A-1 Preferred Shares is to be made in connection with a Public Offering, a Change in Ownership, a Fundamental Change or other transaction affecting the Corporation, the conversion of any Class A-1 Preferred Shares may, at the election of the holder thereof, be conditioned upon the consummation of such transaction, in which case such conversion shall not be deemed to be effective until such transaction has been consummated.

(iv) As soon as possible after a conversion has been effected (but in any event within five (5) business days in the case of subparagraph (A) below), the Corporation shall deliver to the converting holder:

(A) a certificate or certificates representing the number of shares of Common Stock issuable by reason of such conversion in such name or names and such denomination or denominations as the converting holder has specified;

(B) payment in an amount equal to all accrued dividends with respect to each share converted which have not been paid prior thereto, plus the amount payable under subparagraph (ix) below with respect to such conversion; and

(C) a certificate representing any Class A-1 Preferred Shares that were represented by the certificate or certificates delivered to the Corporation in connection with such conversion but that were not converted.

(v) If for any reason the Corporation is unable to pay any portion of the accrued and unpaid dividends on Class A-1 Preferred Shares being converted, such dividends may, at the converting holder’s option, be converted into an additional number of shares of Common Stock determined by dividing the amount of the unpaid dividends to be applied for such purpose, by the fair market value of one share of Common Stock as determined in the reasonable good faith judgment of the Board.

(vi) The issuance of certificates for shares of Common Stock upon conversion of Class A-1 Preferred Shares shall be made without charge to the holders of such Class A-1 Preferred Shares for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such conversion and the related issuance of shares of Common Stock. Upon conversion of each share of Class A-1 Preferred Shares, the Corporation shall take all such actions as are necessary in order to insure that the Common Stock issuable with respect to such conversion shall be validly issued, fully paid and nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the issuance thereof.

(vii) The Corporation shall not close its books against the transfer of Class A-1 Preferred Shares or of Common Stock issued or issuable upon conversion of Class A-1 Preferred Shares in any manner which interferes with the timely conversion of Class A-1 Preferred Shares. The Corporation shall assist and cooperate with any holder of Shares required to make any governmental filings or obtain any governmental approval prior to or in connection with any conversion of Class A-1 Preferred Shares hereunder (including, without limitation, making any filings required to be made by the Corporation).

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).

(ix) If any fractional interest in a share of Common Stock would, except for the provisions of this subparagraph, be delivered upon any conversion of the Class A-1 Preferred Shares, the Corporation, in lieu of delivering the fractional share therefor, shall pay an amount to the holder thereof equal to the fair market value as determined in the reasonable good faith judgment of the Board of such fractional interest as of the date of conversion.

(b) Subdivision or Combination of Common Stock. If the Corporation at any time subdivides (by any stock split, stock dividend or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the amount of Common Stock each holder of Class A-1 Preferred Shares is entitled to upon conversion shall be proportionately increased. Conversely, if the Corporation shall at any time or from time to time combine the outstanding shares of Common Stock into a smaller number of shares, the amount of Common Stock each holder of Class A-1 Preferred Shares is entitled to upon conversion shall be proportionately decreased.

(c) Reorganization, Reclassification, Consolidation, Merger or Sale. Any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or substantially all of the Corporation’s assets or other transaction, in each case that is effected in such a manner that the holders of Common Stock are entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock, is referred to herein as an “Organic Change.” Prior to the consummation of any Organic Change, the Corporation shall make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least two-thirds of the Class A-1 Preferred Shares then outstanding) to insure that each of the holders of Class A-1 Preferred Shares shall thereafter have the right to acquire and receive, in lieu of or in addition to (as the case may be) the shares of Common Stock immediately theretofore acquirable and receivable upon the conversion of such holder’s Class A-1 Preferred Shares, such shares of stock, securities or assets as such holder would have received in connection with such Organic Change if such holder had converted its Class A-1 Preferred Shares immediately prior to such Organic Change. In each such case, the Corporation shall also make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least two-thirds of the Class A-1 Preferred Shares then outstanding) to insure that the provisions of this Section 8 hereof shall thereafter be applicable to the Class A-1 Preferred Shares (including, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is other than the Corporation, an immediate adjustment in the number of shares of Common Stock acquirable and receivable upon conversion of Class A-1 Preferred Shares, if the value per share of common stock so reflected is less than the value of the Common Stock (as reasonably determined by the Board) in effect immediately prior to such consolidation, merger or sale). The Corporation shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor entity (if other than the Corporation) resulting from consolidation or merger or the entity purchasing such assets assumes by written instrument (in form and substance satisfactory to

the holders of at least two-thirds of the Class A-1 Preferred Shares 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.

(d) Mandatory Conversion. The Corporation may at any time require the conversion of all of the outstanding Class A-1 Preferred Shares upon the closing of a firmly underwritten public offering of shares of Common Stock.

Section 9. Registration of Transfer. The Corporation shall keep at its principal office a register for the registration of Class A-1 Preferred Shares. Upon the surrender of any certificate representing Class A-1 Preferred Shares at such place, the Corporation shall, at the request of the record holder of such certificate, execute and deliver (at the Corporation’s expense) a new certificate or certificates in exchange therefor representing in the aggregate the number of shares of Class A-1 Preferred Shares represented by the surrendered certificate. Each such new certificate shall be registered in such name and shall represent such number of shares of Class A-1 Preferred Shares as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Class A-1 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such Class A-1 Preferred Shares represented by the surrendered certificate.

Section 10. Replacement. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing Class A-1 Preferred Shares, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor its own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such Class A-Preferred Shares represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on the Class A-1 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate.

Section 11. Amendment and Waiver. No amendment, modification or waiver shall be binding or effective with respect to this paragraph (a) of this Article Sixth hereof without the prior written consent of the holders of at least two-thirds of the Class A-1 Preferred Shares outstanding at the time such action is taken and provided further that no change in the terms hereof may be accomplished by merger or consolidation of the Corporation with another corporation or entity unless the Corporation has obtained the prior written consent of the holders of at least the applicable percentage of the Class A-1 Preferred Shares then outstanding.

mail, return receipt requested and postage prepaid, or transmitted by facsimile or electronic mail (with request for immediate confirmation of receipt in a manner customary for communications of such type and with physical delivery of the communication being made by one of the other means specified in this Section 12 as promptly as practicable thereafter). Such notices, demands and other communications shall be addressed (i) in the case of a holder of Class A-1 Preferred Shares, to his address as is designated in writing from time to time by such holder, (ii) in the case of the Corporation, to its principal office.

Except as otherwise provided herein, if at any time the Corporation pays less than the total amount of dividends then accrued with respect to the Class A Preferred Shares, such payment shall be distributed pro rata among the holders thereof based upon the number of Class A Preferred Shares held by each such holder.

Section 5. Liquidation. Upon any liquidation, dissolution or winding up of the Corporation (whether voluntary or involuntary), each holder of Class A-2 Preferred Shares shall be entitled to be paid, before any distribution or payment is made upon any Junior Securities, an amount equal to the greater of (i) the aggregate Liquidation Value of all Class A-2 Preferred Shares (plus all accrued and unpaid dividends thereon) held by such holder or (ii) the amount such holder of Class A-2 Preferred Shares would be entitled to receive if all Class A Preferred Shares were converted into Common Stock (the “Liquidation Amount”). All holders of Class A Preferred Shares shall be pari passu with respect to their entitlement to receive their respective Liquidation Amounts. If upon any such liquidation, dissolution or winding up of the Corporation, the Corporation’s assets to be distributed among the holders of the Class A Preferred Shares are insufficient to permit payment to such holders of the aggregate amount which they are entitled to

be paid, then the entire assets available to be distributed to the Corporation’s Class A Preferred Shares stockholders shall be distributed pro rata among such holders based upon the aggregate Liquidation Amount of the Class A Preferred Shares held by each such holder. Prior to the liquidation, dissolution or winding up of the Corporation, the Corporation shall declare for payment all accrued and unpaid dividends with respect to the Class A Preferred Shares, but only to the extent of funds of the Corporation legally available for the payment of dividends. Not less than sixty (60) days prior to the payment date stated therein, the Corporation shall mail written notice of any such liquidation, dissolution or winding up to each record holder of Class A Preferred Shares, setting forth in reasonable detail the amount of proceeds to be paid with respect to each Class A Preferred Share and each share of Common Stock in connection with such liquidation, dissolution or winding up.

Section 6. Voting Rights. Subject to Section 7 below and the Shareholders’ Agreement, the holders of the Class A-2 Preferred Shares shall be entitled to notice of all stockholders meetings in accordance with the Corporation’s Bylaws. Except as otherwise required by applicable law, the holders of the Class A-2 Preferred Shares shall be entitled to vote on all matters submitted to the stockholders for a vote (whether at a meeting or by written consent) together with the holders of the Common Stock, Class A-1 5% Convertible Preferred Stock, the Class A-3 5% Convertible Preferred Stock, Class A-4 5% Convertible Preferred Stock, the Class A-5 5% Convertible Preferred Stock, the Class A-6 5% Convertible Preferred Stock, the Class A-7 5% Convertible Preferred Stock, the Class A-8 5% Convertible Preferred Stock, the Class AA Convertible Preferred Stock, the Class AB Convertible Preferred Stock and any Subsequent Class A Shares, all voting together as a single class. Each holder of shares of Class A-1 Preferred Shares, Class A-2 5% Convertible Preferred Stock, Class A-3 5% Convertible Preferred Stock, Class A-4 5% Convertible Preferred Stock, Class A-5 5% Convertible Preferred Stock, Class A-6 5% Convertible Preferred Stock, Class A-7 5% Convertible Preferred Stock, Class A-8 5% Convertible Preferred Stock, Class AA Convertible Preferred Stock, Class AB Convertible Preferred Stock and/or any Subsequent Class A Shares shall be entitled to a number of votes (rounded to the nearest whole number) equal to the number of shares of Common Stock into which such shares are convertible (pursuant to the conversion terms of the applicable class of stock as set forth in these Articles) immediately after the close of business on the record date fixed for such meeting or the effective date of such written consent.

Section 7. Special Voting Rights. The consent of the holders of at least two-thirds of the Class A-2 Preferred Shares, voting together as a single class, shall be required for any action that (a) authorizes or issues shares of any class of stock having any preference or priority superior to any preference or priority of the Class A-2 Preferred Shares (which shall not include the authorization or issuance of any Subsequent Class A Shares) or (b) changes the number of shares or class of stock into which the Class A-2 Preferred Shares is convertible.

Section 8. Conversion.

(a) Conversion Procedure.

(i) At any time and from time to time, any holder of Class A-2 Preferred Shares may convert all or any portion of the Class A-2 Preferred Shares held by such

holder into 1.8 shares of Common Stock per each share of Class A-2 Preferred Shares (which gives effect to the 0.8 for one stock dividend declared on the Common Stock on February 23, 2001).

(ii) Except as otherwise provided herein, each conversion of Class A-2 Preferred Shares shall be deemed to have been effected as of the close of business on the date on which the certificate or certificates representing the Class A-2 Preferred Shares to be converted have been surrendered for conversion at the principal office of the Corporation. At the time any such conversion has been effected, the rights of the holder of the shares converted as a holder of Class A-2 Preferred Shares shall cease and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the shares of Common Stock represented thereby.

(iii) Notwithstanding any other provision hereof, if a conversion of Class A-2 Preferred Shares is to be made in connection with a Public Offering, a Change in Ownership, a Fundamental Change or other transaction affecting the Corporation, the conversion of any Class A-2 Preferred Shares may, at the election of the holder thereof, be conditioned upon the consummation of such transaction, in which case such conversion shall not be deemed to be effective until such transaction has been consummated.

(C) a certificate representing any Class A-2 Preferred Shares that were represented by the certificate or certificates delivered to the Corporation in connection with such conversion but that were not converted.

(v) If for any reason the Corporation is unable to pay any portion of the accrued and unpaid dividends on Class A-2 Preferred Shares being converted, such dividends may, at the converting holder’s option, be converted into an additional number of shares of Common Stock determined by dividing the amount of the unpaid dividends to be applied for such purpose, by the fair market value of one share of Common Stock as determined in the reasonable good faith judgment of the Board.

(vi) The issuance of certificates for shares of Common Stock upon conversion of Class A-2 Preferred Shares shall be made without charge to the holders of such Class A-2 Preferred Shares for any issuance tax in respect thereof or other cost incurred by the

Corporation in connection with such conversion and the related issuance of shares of Common Stock. Upon conversion of each share of Class A-2 Preferred Shares, the Corporation shall take all such actions as are necessary in order to insure that the Common Stock issuable with respect to such conversion shall be validly issued, fully paid and nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the issuance thereof.

(vii) The Corporation shall not close its books against the transfer of Class A-2 Preferred Shares or of Common Stock issued or issuable upon conversion of Class A-2 Preferred Shares in any manner which interferes with the timely conversion of Class A-2 Preferred Shares. The Corporation shall assist and cooperate with any holder of Shares required to make any governmental filings or obtain any governmental approval prior to or in connection with any conversion of Class A-2 Preferred Shares hereunder (including, without limitation, making any filings required to be made by the Corporation).

(viii) The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of issuance upon the conversion of the Class A-2 Preferred Shares, such number of shares of Common Stock issuable upon the conversion of all outstanding Class A-2 Preferred Shares. All shares of Common Stock that are so issuable shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. 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).

(ix) If any fractional interest in a share of Common Stock would, except for the provisions of this subparagraph, be delivered upon any conversion of the Class A-2 Preferred Shares, the Corporation, in lieu of delivering the fractional share therefor, shall pay an amount to the holder thereof equal to the fair market value as determined in the reasonable good faith judgment of the Board of such fractional interest as of the date of conversion.

(b) Subdivision or Combination of Common Stock. If the Corporation at any time subdivides (by any stock split, stock dividend or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the amount of Common Stock each holder of Class A-2 Preferred Shares is entitled to upon conversion shall be proportionately increased. Conversely, if the Corporation shall at any time or from time to time combine the outstanding shares of Common Stock into a smaller number of shares, the amount of Common Stock each holder of Class A-2 Preferred Shares is entitled to upon conversion shall be proportionately decreased.

Stock, is referred to herein as an “Organic Change.” Prior to the consummation of any Organic Change, the Corporation shall make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least two-thirds of the Class A-2 Preferred Shares then outstanding) to insure that each of the holders of Class A-2 Preferred Shares shall thereafter have the right to acquire and receive, in lieu of or in addition to (as the case may be) the shares of Common Stock immediately theretofore acquirable and receivable upon the conversion of such holder’s Class A-2 Preferred Shares, such shares of stock, securities or assets as such holder would have received in connection with such Organic Change if such holder had converted its Class A-2 Preferred Shares immediately prior to such Organic Change. In each such case, the Corporation shall also make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least two-thirds of the Class A-2 Preferred Shares then outstanding) to insure that the provisions of this Section 8 hereof shall thereafter be applicable to the Class A-2 Preferred Shares (including, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is other than the Corporation, an immediate adjustment in the number of shares of Common Stock acquirable and receivable upon conversion of Class A-2 Preferred Shares, if the value per share of common stock so reflected is less than the value of the Common Stock (as reasonably determined by the Board) in effect immediately prior to such consolidation, merger or sale). The Corporation shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor entity (if other than the Corporation) resulting from consolidation or merger or the entity purchasing such assets assumes by written instrument (in form and substance satisfactory to the holders of at least two-thirds of the Class A-2 Preferred Shares 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.

(d) Mandatory Conversion. The Corporation may at any time require the conversion of all of the outstanding Class A-2 Preferred Shares upon the closing of a firmly underwritten public offering of shares of Common Stock.

Section 9. Registration of Transfer. The Corporation shall keep at its principal office a register for the registration of Class A-2 Preferred Shares. Upon the surrender of any certificate representing Class A-2 Preferred Shares at such place, the Corporation shall, at the request of the record holder of such certificate, execute and deliver (at the Corporation’s expense) a new certificate or certificates in exchange therefor representing in the aggregate the number of shares of Class A-2 Preferred Shares represented by the surrendered certificate. Each such new certificate shall be registered in such name and shall represent such number of shares of Class A-2 Preferred Shares as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Class A-2 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such Class A-2 Preferred Shares represented by the surrendered certificate.

surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such Class A-2 Preferred Shares represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on the Class A-2 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate.

Section 11. Amendment and Waiver. No amendment, modification or waiver shall be binding or effective with respect to this paragraph (b) of this Article Sixth hereof without the prior written consent of the holders of at least two-thirds of the Class A-2 Preferred Shares outstanding at the time such action is taken and provided further that no change in the terms hereof may be accomplished by merger or consolidation of the Corporation with another corporation or entity unless the Corporation has obtained the prior written consent of the holders of at least the applicable percentage of the Class A-2 Preferred Shares then outstanding.

Section 12. Notices. Except as otherwise expressly provided hereunder, all notices, demands or other communications to be given or delivered under or by reason of the provisions of this paragraph (b) of this Article Sixth shall be in writing and shall be deemed to have been given when delivered personally to the recipient, sent to the recipient by reputable overnight courier service (charges prepaid), mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid, or transmitted by facsimile or electronic mail (with request for immediate confirmation of receipt in a manner customary for communications of such type and with physical delivery of the communication being made by one of the other means specified in this Section 12 as promptly as practicable thereafter). Such notices, demands and other communications shall be addressed (i) in the case of a holder of Class A-2 Preferred Shares, to his address as is designated in writing from time to time by such holder, (ii) in the case of the Corporation, to its principal office.

Section 8. Conversion.

(a) Conversion Procedure.

(i) At any time and from time to time, any holder of Class A-3 Preferred Shares may convert all or any portion of the Class A-3 Preferred Shares held by such holder into 1.8 shares of Common Stock per each share of Class A-3 Preferred Shares (which gives effect to the 0.8 for one stock dividend declared on the Common Stock on February 23, 2001).

(ii) Except as otherwise provided herein, each conversion of Class A-3 Preferred Shares shall be deemed to have been effected as of the close of business on the date on which the certificate or certificates representing the Class A-3 Preferred Shares to be converted have been surrendered for conversion at the principal office of the Corporation. At the time any such conversion has been effected, the rights of the holder of the shares converted as a holder of Class A-3 Preferred Shares shall cease and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the shares of Common Stock represented thereby.

(iii) Notwithstanding any other provision hereof, if a conversion of Class A-3 Preferred Shares is to be made in connection with a Public Offering, a Change in Ownership, a Fundamental Change or other transaction affecting the Corporation, the conversion of any Class A-3 Preferred Shares may, at the election of the holder thereof, be conditioned upon the consummation of such transaction, in which case such conversion shall not be deemed to be effective until such transaction has been consummated.

(C) a certificate representing any Class A-3 Preferred Shares that were represented by the certificate or certificates delivered to the Corporation in connection with such conversion but that were not converted.

(v) If for any reason the Corporation is unable to pay any portion of the accrued and unpaid dividends on Class A-3 Preferred Shares being converted, such dividends may, at the converting holder’s option, be converted into an additional number of shares of Common Stock determined by dividing the amount of the unpaid dividends to be applied for such purpose, by the fair market value of one share of Common Stock as determined in the reasonable good faith judgment of the Board.

(vi) The issuance of certificates for shares of Common Stock upon conversion of Class A-3 Preferred Shares shall be made without charge to the holders of such Class A-3 Preferred Shares for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such conversion and the related issuance of shares of Common Stock. Upon conversion of each share of Class A-3 Preferred Shares, the Corporation shall take all such actions as are necessary in order to insure that the Common Stock issuable with respect to such conversion shall be validly issued, fully paid and nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the issuance thereof.

(vii) The Corporation shall not close its books against the transfer of Class A-3 Preferred Shares or of Common Stock issued or issuable upon conversion of Class A-3 Preferred Shares in any manner which interferes with the timely conversion of Class A-3 Preferred Shares. The Corporation shall assist and cooperate with any holder of Shares required to make any governmental filings or obtain any governmental approval prior to or in connection with any conversion of Class A-3 Preferred Shares hereunder (including, without limitation, making any filings required to be made by the Corporation).

(viii) The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of issuance upon the conversion of the Class A-3 Preferred Shares, such number of shares of Common Stock issuable upon the conversion of all outstanding Class A-3 Preferred Shares. All shares of Common Stock that are so issuable shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. 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).

(ix) If any fractional interest in a share of Common Stock would, except for the provisions of this subparagraph, be delivered upon any conversion of the Class A-3 Preferred Shares, the Corporation, in lieu of delivering the fractional share therefor, shall pay an amount to the holder thereof equal to the fair market value as determined in the reasonable good faith judgment of the Board of such fractional interest as of the date of conversion.

(b) Subdivision or Combination of Common Stock. If the Corporation at any time subdivides (by any stock split, stock dividend or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the amount of Common Stock each holder of Class A-3 Preferred Shares is entitled to upon conversion shall be proportionately increased. Conversely, if the Corporation shall at any time or from time to time combine the outstanding shares of Common Stock into a smaller number of shares, the amount of Common Stock each holder of Class A-3 Preferred Shares is entitled to upon conversion shall be proportionately decreased.

(c) Reorganization, Reclassification, Consolidation, Merger or Sale. Any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or substantially all of the Corporation’s assets or other transaction, in each case that is effected in such a manner that the holders of Common Stock are entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock, is referred to herein as an “Organic Change.” Prior to the consummation of any Organic Change, the Corporation shall make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least two-thirds of the Class A-3 Preferred Shares then outstanding) to insure that each of the holders of Class A-3 Preferred Shares shall thereafter have the right to acquire and receive, in lieu of or in addition to (as the case may be) the shares of Common Stock immediately theretofore acquirable and receivable upon the conversion of such holder’s Class A-3 Preferred Shares, such shares of stock, securities or assets as such holder would have received in connection with such Organic Change if such holder had converted its Class A-3 Preferred Shares immediately prior to such Organic Change. In each such case, the Corporation shall also make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least two-thirds of the Class A-3 Preferred Shares then outstanding) to insure that the provisions of this Section 8 hereof shall thereafter be applicable to the Class A-3 Preferred Shares (including, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is other than the Corporation, an immediate adjustment in the number of shares of Common Stock acquirable and receivable upon conversion of Class A-3 Preferred Shares, if the value per share of common stock so reflected is less than the value of the Common Stock (as reasonably determined by the Board) in effect immediately prior to such consolidation, merger or sale). The Corporation shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor entity (if other than the Corporation) resulting from consolidation or merger or the entity purchasing such assets assumes by written instrument (in form and substance satisfactory to the holders of at least two-thirds of the Class A-3 Preferred Shares 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.

(d) Mandatory Conversion. The Corporation may at any time require the conversion of all of the outstanding Class A-3 Preferred Shares upon the closing of a firmly underwritten public offering of shares of Common Stock.

Each such new certificate shall be registered in such name and shall represent such number of shares of Class A-3 Preferred Shares as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Class A-3 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such Class A-3 Preferred Shares represented by the surrendered certificate.

Section 10. Replacement. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing Class A-3 Preferred Shares, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor its own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such Class A-3 Preferred Shares represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on the Class A-3 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate.

Section 11. Amendment and Waiver. No amendment, modification or waiver shall be binding or effective with respect to this paragraph (c) of this Article Sixth hereof without the prior written consent of the holders of at least two-thirds of the Class A-3 Preferred Shares outstanding at the time such action is taken and provided further that no change in the terms hereof may be accomplished by merger or consolidation of the Corporation with another corporation or entity unless the Corporation has obtained the prior written consent of the holders of at least the applicable percentage of the Class A-3 Preferred Shares then outstanding.

Such number of shares may be decreased by resolution of the Board adopted and filed pursuant to applicable law; provided, that no such decrease shall reduce the number of authorized Class A-4 Preferred Shares to a number less than the number of shares then outstanding plus the number of shares reserved for issuance upon the exercise of outstanding options, warrants, convertible or exchangeable securities or other rights to acquire Class A-4 Preferred Shares.

Section 3. Priority. The Class A-4 Preferred Shares shall rank (i) prior to all of the shares of Junior Securities, (ii) pari passu with all Class A Preferred Shares, and (iii) subordinate to all of the Class C Preferred Shares. In addition, so long as any Class A-4 Preferred Shares remain outstanding, without the prior written consent of the holders of two-thirds of the outstanding shares of Class A-4 Preferred Shares, the Corporation shall not, nor shall it permit any Subsidiary to, redeem, purchase or otherwise acquire directly or indirectly any Junior Securities; provided that the Corporation may purchase, redeem, acquire or retire for value shares of Junior Securities held by current or former directors or officers of the Company or any of its Subsidiaries upon death, disability, retirement, termination of employment or pursuant to the terms of any plan or other agreement under which such Junior Securities were issued to the extent permitted by the terms of the credit facility or facilities of the Corporation or its Subsidiaries.

Except with respect to dividends for which an adjustment is made pursuant to Section 8(b) hereof, no dividends will be paid on any Junior Securities until dividends have been declared and paid on Class A-4 Preferred Shares. All holders of Class A Preferred Shares shall be pari passu with respect to their entitlement to receive dividends. After payment of all dividends on Class A-4 Preferred Shares, the holders of Class A-4 Preferred Shares shall be entitled to participate, on an as converted basis, with the outstanding Common Stock as to any dividends payable on the Common Stock. The date on which any share of Class A-4 Preferred Shares is initially issued by the Corporation (or its predecessor) shall be deemed to be its “date of issuance” regardless of the number of times transfer of such share is made on the stock records maintained by or for the Corporation and regardless of the number of certificates which may be issued to evidence such share. Each certificate shall have a legend indicating the “date of issuance” for purposes of the dividend calculation referred to herein.

All holders of Class A Preferred Shares shall be pari passu with respect to their entitlement to receive their respective Liquidation Amounts. If upon any such liquidation, dissolution or winding up of the Corporation, the Corporation’s assets to be distributed among the holders of the Class A Preferred Shares are insufficient to permit payment to such holders of the aggregate amount which they are entitled to be paid, then the entire assets available to be distributed to the Corporation’s Class A Preferred Shares stockholders shall be distributed pro rata among such holders based upon the aggregate Liquidation Amount of the Class A Preferred Shares held by each such holder. Prior to the liquidation, dissolution or winding up of the Corporation, the Corporation shall declare for

payment all accrued and unpaid dividends with respect to the Class A Preferred Shares, but only to the extent of funds of the Corporation legally available for the payment of dividends. Not less than sixty (60) days prior to the payment date stated therein, the Corporation shall mail written notice of any such liquidation, dissolution or winding up to each record holder of Class A Preferred Shares, setting forth in reasonable detail the amount of proceeds to be paid with respect to each Class A Preferred Share and each share of Common Stock in connection with such liquidation, dissolution or winding up.

Section 7. Special Voting Rights. The consent of the holders of at least two-thirds of the Class A-4 Preferred Shares, voting together as a single class, shall be required for any action that (a) authorizes or issues shares of any class of stock having any preference or priority superior to any preference or priority of the Class A-4 Preferred Shares (which shall not include the authorization or issuance of any Subsequent Class A Shares) or (b) changes the number of shares or class of stock into which the Class A-4 Preferred Shares is convertible.

Section 8. Conversion.

(a) Conversion Procedure.

(i) At any time and from time to time, any holder of Class A-4 Preferred Shares may convert all or any portion of the Class A-4 Preferred Shares held by such holder into 1.8 shares of Common Stock per each share of Class A-4 Preferred Shares (which gives effect to the 0.8 for one stock dividend declared on the Common Stock on February 23, 2001).

(ii) Except as otherwise provided herein, each conversion of Class A-4 Preferred Shares shall be deemed to have been effected as of the close of business on the date on which the certificate or certificates representing the Class A-4 Preferred Shares to be converted have been surrendered for conversion at the principal office of the Corporation. At the time any such conversion has been effected, the rights of the holder of the shares converted as a holder of Class A-4 Preferred Shares shall cease and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the shares of Common Stock represented thereby.

(iii) Notwithstanding any other provision hereof, if a conversion of Class A-4 Preferred Shares is to be made in connection with a Public Offering, a Change in Ownership, a Fundamental Change or other transaction affecting the Corporation, the conversion of any Class A-4 Preferred Shares may, at the election of the holder thereof, be conditioned upon the consummation of such transaction, in which case such conversion shall not be deemed to be effective until such transaction has been consummated.

(C) a certificate representing any Class A-4 Preferred Shares that were represented by the certificate or certificates delivered to the Corporation in connection with such conversion but that were not converted.

(v) If for any reason the Corporation is unable to pay any portion of the accrued and unpaid dividends on Class A-4 Preferred Shares being converted, such dividends may, at the converting holder’s option, be converted into an additional number of shares of Common Stock determined by dividing the amount of the unpaid dividends to be applied for such purpose, by the fair market value of one share of Common Stock as determined in the reasonable good faith judgment of the Board.

(vi) The issuance of certificates for shares of Common Stock upon conversion of Class A-4 Preferred Shares shall be made without charge to the holders of such Class A-4 Preferred Shares for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such conversion and the related issuance of shares of Common Stock. Upon conversion of each share of Class A-4 Preferred Shares, the Corporation shall take all such actions as are necessary in order to insure that the Common Stock issuable with respect to

such conversion shall be validly issued, fully paid and nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the issuance thereof.

(vii) The Corporation shall not close its books against the transfer of Class A-4 Preferred Shares or of Common Stock issued or issuable upon conversion of Class A-4 Preferred Shares in any manner which interferes with the timely conversion of Class A-4 Preferred Shares. The Corporation shall assist and cooperate with any holder of Shares required to make any governmental filings or obtain any governmental approval prior to or in connection with any conversion of Class A-4 Preferred Shares hereunder (including, without limitation, making any filings required to be made by the Corporation).

(viii) The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of issuance upon the conversion of the Class A-4 Preferred Shares, such number of shares of Common Stock issuable upon the conversion of all outstanding Class A-4 Preferred Shares. All shares of Common Stock that are so issuable shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. 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).

(ix) If any fractional interest in a share of Common Stock would, except for the provisions of this subparagraph, be delivered upon any conversion of the Class A-4 Preferred Shares, the Corporation, in lieu of delivering the fractional share therefor, shall pay an amount to the holder thereof equal to the fair market value as determined in the reasonable good faith judgment of the Board of such fractional interest as of the date of conversion.

(b) Subdivision or Combination of Common Stock. If the Corporation at any time subdivides (by any stock split, stock dividend or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the amount of Common Stock each holder of Class A-4 Preferred Shares is entitled to upon conversion shall be proportionately increased. Conversely, if the Corporation shall at any time or from time to time combine the outstanding shares of Common Stock into a smaller number of shares, the amount of Common Stock each holder of Class A-4 Preferred Shares is entitled to upon conversion shall be proportionately decreased.

to insure that each of the holders of Class A-4 Preferred Shares shall thereafter have the right to acquire and receive, in lieu of or in addition to (as the case may be) the shares of Common Stock immediately theretofore acquirable and receivable upon the conversion of such holder’s Class A-4 Preferred Shares, such shares of stock, securities or assets as such holder would have received in connection with such Organic Change if such holder had converted its Class A-4 Preferred Shares immediately prior to such Organic Change. In each such case, the Corporation shall also make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least two-thirds of the Class A-4 Preferred Shares then outstanding) to insure that the provisions of this Section 8 hereof shall thereafter be applicable to the Class A-4 Preferred Shares (including, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is other than the Corporation, an immediate adjustment in the number of shares of Common Stock acquirable and receivable upon conversion of Class A-4 Preferred Shares, if the value per share of common stock so reflected is less than the value of the Common Stock (as reasonably determined by the Board) in effect immediately prior to such consolidation, merger or sale). The Corporation shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor entity (if other than the Corporation) resulting from consolidation or merger or the entity purchasing such assets assumes by written instrument (in form and substance satisfactory to the holders of at least two-thirds of the Class A-4 Preferred Shares 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.

(d) Mandatory Conversion. The Corporation may at any time require the conversion of all of the outstanding Class A-4 Preferred Shares upon the closing of a firmly underwritten public offering of shares of Common Stock.

Section 9. Registration of Transfer. The Corporation shall keep at its principal office a register for the registration of Class A-4 Preferred Shares. Upon the surrender of any certificate representing Class A-4 Preferred Shares at such place, the Corporation shall, at the request of the record holder of such certificate, execute and deliver (at the Corporation’s expense) a new certificate or certificates in exchange therefor representing in the aggregate the number of shares of Class A-4 Preferred Shares represented by the surrendered certificate. Each such new certificate shall be registered in such name and shall represent such number of shares of Class A-4 Preferred Shares as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Class A-4 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such Class A-4 Preferred Shares represented by the surrendered certificate.

Section 10. Replacement. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing Class A-4 Preferred Shares, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor its own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such Class A-4 Preferred Shares represented by such lost, stolen, destroyed or mutilated certificate and dated the

date of such lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on the Class A-4 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate.

Section 11. Amendment and Waiver. No amendment, modification or waiver shall be binding or effective with respect to this paragraph (d) of this Article Sixth hereof without the prior written consent of the holders of at least two-thirds of the Class A-4 Preferred Shares outstanding at the time such action is taken and provided further that no change in the terms hereof may be accomplished by merger or consolidation of the Corporation with another corporation or entity unless the Corporation has obtained the prior written consent of the holders of at least the applicable percentage of the Class A-4 Preferred Shares then outstanding.

Section 12. Notices. Except as otherwise expressly provided hereunder, all notices, demands or other communications to be given or delivered under or by reason of the provisions of this paragraph (d) of this Article Sixth shall be in writing and shall be deemed to have been given when delivered personally to the recipient, sent to the recipient by reputable overnight courier service (charges prepaid), mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid, or transmitted by facsimile or electronic mail (with request for immediate confirmation of receipt in a manner customary for communications of such type and with physical delivery of the communication being made by one of the other means specified in this Section 12 as promptly as practicable thereafter). Such notices, demands and other communications shall be addressed (i) in the case of a holder of Class A-4 Preferred Shares, to his address as is designated in writing from time to time by such holder, (ii) in the case of the Corporation, to its principal office.

(a) Conversion Procedure.

(i) At any time and from time to time, any holder of Class A-5 Preferred Shares may convert all or any portion of the Class A-5 Preferred Shares held by such holder into 1.8 shares of Common Stock per each share of Class A-5 Preferred Shares (which gives effect to the 0.8 for one stock dividend declared on the Common Stock on February 23, 2001).

(ii) Except as otherwise provided herein, each conversion of Class A-5 Preferred Shares shall be deemed to have been effected as of the close of business on the date on which the certificate or certificates representing the Class A-5 Preferred Shares to be converted have been surrendered for conversion at the principal office of the Corporation. At the time any such conversion has been effected, the rights of the holder of the shares converted as a holder of Class A-5 Preferred Shares shall cease and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the shares of Common Stock represented thereby.

(iii) Notwithstanding any other provision hereof, if a conversion of Class A-5 Preferred Shares is to be made in connection with a Public Offering, a Change in Ownership, a Fundamental Change or other transaction affecting the Corporation, the conversion of any Class A-5 Preferred Shares may, at the election of the holder thereof, be conditioned upon the consummation of such transaction, in which case such conversion shall not be deemed to be effective until such transaction has been consummated.

(C) a certificate representing any Class A-5 Preferred Shares that were represented by the certificate or certificates delivered to the Corporation in connection with such conversion but that were not converted.

(v) If for any reason the Corporation is unable to pay any portion of the accrued and unpaid dividends on Class A-5 Preferred Shares being converted, such dividends may, at the converting holder’s option, be converted into an additional number of shares of Common Stock determined by dividing the amount of the unpaid dividends to be applied for such purpose, by the fair market value of one share of Common Stock as determined in the reasonable good faith judgment of the Board.

(vi) The issuance of certificates for shares of Common Stock upon conversion of Class A-5 Preferred Shares shall be made without charge to the holders of such Class A-5 Preferred Shares for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such conversion and the related issuance of shares of Common Stock. Upon conversion of each share of Class A-5 Preferred Shares, the Corporation shall take all such actions as are necessary in order to insure that the Common Stock issuable with respect to such conversion shall be validly issued, fully paid and nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the issuance thereof.

(vii) The Corporation shall not close its books against the transfer of Class A-5 Preferred Shares or of Common Stock issued or issuable upon conversion of Class A-5 Preferred Shares in any manner which interferes with the timely conversion of Class A-5 Preferred Shares. The Corporation shall assist and cooperate with any holder of Shares required to make any governmental filings or obtain any governmental approval prior to or in connection with any conversion of Class A-5 Preferred Shares hereunder (including, without limitation, making any filings required to be made by the Corporation).

(viii) The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of issuance upon the conversion of the Class A-5 Preferred Shares, such number of shares of Common Stock issuable upon the conversion of all outstanding Class A-5 Preferred Shares. All shares of Common Stock that are so issuable shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. 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).

(ix) If any fractional interest in a share of Common Stock would, except for the provisions of this subparagraph, be delivered upon any conversion of the Class A-5

Preferred Shares, the Corporation, in lieu of delivering the fractional share therefor, shall pay an amount to the holder thereof equal to the fair market value as determined in the reasonable good faith judgment of the Board of such fractional interest as of the date of conversion.

(b) Subdivision or Combination of Common Stock. If the Corporation at any time subdivides (by any stock split, stock dividend or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the amount of Common Stock each holder of Class A-5 Preferred Shares is entitled to upon conversion shall be proportionately increased.

(ii) Except as otherwise provided herein, each conversion of Class A-6 Preferred Shares shall be deemed to have been effected as of the close of business on the date on which the certificate or certificates representing the Class A-6 Preferred Shares to be converted have been surrendered for conversion at the principal office of the Corporation. At the time any such conversion has been effected, the rights of the holder of the shares converted as a holder of Class A-6 Preferred Shares shall cease and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock are to be issued upon such

conversion shall be deemed to have become the holder or holders of record of the shares of Common Stock represented thereby.

(iii) Notwithstanding any other provision hereof, if a conversion of Class A-6 Preferred Shares is to be made in connection with a Public Offering, a Change in Ownership, a Fundamental Change or other transaction affecting the Corporation, the conversion of any Class A-6 Preferred Shares may, at the election of the holder thereof, be conditioned upon the consummation of such transaction, in which case such conversion shall not be deemed to be effective until such transaction has been consummated.

(C) a certificate representing any Class A-6 Preferred Shares that were represented by the certificate or certificates delivered to the Corporation in connection with such conversion but that were not converted.

(v) If for any reason the Corporation is unable to pay any portion of the accrued and unpaid dividends on Class A-6 Preferred Shares being converted, such dividends may, at the converting holder’s option, be converted into an additional number of shares of Common Stock determined by dividing the amount of the unpaid dividends to be applied for such purpose, by the fair market value of one share of Common Stock as determined in the reasonable good faith judgment of the Board.

(vi) The issuance of certificates for shares of Common Stock upon conversion of Class A-6 Preferred Shares shall be made without charge to the holders of such Class A-6 Preferred Shares for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such conversion and the related issuance of shares of Common Stock. Upon conversion of each share of Class A-6 Preferred Shares, the Corporation shall take all such actions as are necessary in order to insure that the Common Stock issuable with respect to such conversion shall be validly issued, fully paid and nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the issuance thereof.

(vii) The Corporation shall not close its books against the transfer of Class A-6 Preferred Shares or of Common Stock issued or issuable upon conversion of Class A-6 Preferred Shares in any manner which interferes with the timely conversion of Class A-6 Preferred Shares. The Corporation shall assist and cooperate with any holder of Shares required to

make any governmental filings or obtain any governmental approval prior to or in connection with any conversion of Class A-6 Preferred Shares hereunder (including, without limitation, making any filings required to be made by the Corporation).

All shares of Common Stock that are so issuable shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. 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).

(ix) If any fractional interest in a share of Common Stock would, except for the provisions of this subparagraph, be delivered upon any conversion of the Class A-6 Preferred Shares, the Corporation, in lieu of delivering the fractional share therefor, shall pay an amount to the holder thereof equal to the fair market value as determined in the reasonable good faith judgment of the Board of such fractional interest as of the date of conversion.

(b) Subdivision or Combination of Common Stock. If the Corporation at any time subdivides (by any stock split, stock dividend or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the amount of Common Stock each holder of Class A-6 Preferred Shares is entitled to upon conversion shall be proportionately increased. Conversely, if the Corporation shall at any time or from time to time combine the outstanding shares of Common Stock into a smaller number of shares, the amount of Common Stock each holder of Class A-6 Preferred Shares is entitled to upon conversion shall be proportionately decreased.

Section 8. Conversion.

(a) Conversion Procedure.

(i) At any time and from time to time, any holder of Class A-7 Preferred Shares may convert all or any portion of the Class A-7 Preferred Shares held by such holder into 1.8 shares of Common Stock per each share of Class A-7 Preferred Shares.

(ii) Except as otherwise provided herein, each conversion of Class A-7 Preferred Shares shall be deemed to have been effected as of the close of business on the date on which the certificate or certificates representing the Class A-7 Preferred Shares to be converted have been surrendered for conversion at the principal office of the Corporation. At the time any such conversion has been effected, the rights of the holder of the shares converted as a holder of Class A-7 Preferred Shares shall cease and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the shares of Common Stock represented thereby.

(iii) Notwithstanding any other provision hereof, if a conversion of Class A-7 Preferred Shares is to be made in connection with a Public Offering, a Change in Ownership, a Fundamental Change or other transaction affecting the Corporation, the conversion of any Class A-7 Preferred Shares may, at the election of the holder thereof, be conditioned upon the consummation of such transaction, in which case such conversion shall not be deemed to be effective until such transaction has been consummated.

(C) a certificate representing any Class A-7 Preferred Shares that were represented by the certificate or certificates delivered to the Corporation in connection with such conversion but that were not converted.

(v) If for any reason the Corporation is unable to pay any portion of the accrued and unpaid dividends on Class A-7 Preferred Shares being converted, such

dividends may, at the converting holder’s option, be converted into an additional number of shares of Common Stock determined by dividing the amount of the unpaid dividends to be applied for such purpose, by the fair market value of one share of Common Stock as determined in the reasonable good faith judgment of the Board.

(vi) The issuance of certificates for shares of Common Stock upon conversion of Class A-7 Preferred Shares shall be made without charge to the holders of such Class A-7 Preferred Shares for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such conversion and the related issuance of shares of Common Stock. Upon conversion of each share of Class A-7 Preferred Shares, the Corporation shall take all such actions as are necessary in order to insure that the Common Stock issuable with respect to such conversion shall be validly issued, fully paid and nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the issuance thereof.

(vii) The Corporation shall not close its books against the transfer of Class A-7 Preferred Shares or of Common Stock issued or issuable upon conversion of Class A-7 Preferred Shares in any manner which interferes with the timely conversion of Class A-7 Preferred Shares. The Corporation shall assist and cooperate with any holder of Shares required to make any governmental filings or obtain any governmental approval prior to or in connection with any conversion of Class A-7 Preferred Shares hereunder (including, without limitation, making any filings required to be made by the Corporation).

(viii) The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of issuance upon the conversion of the Class A-7 Preferred Shares, such number of shares of Common Stock issuable upon the conversion of all outstanding Class A-7 Preferred Shares. All shares of Common Stock that are so issuable shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. 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).

(ix) If any fractional interest in a share of Common Stock would, except for the provisions of this subparagraph, be delivered upon any conversion of the Class A-7 Preferred Shares, the Corporation, in lieu of delivering the fractional share therefor, shall pay an amount to the holder thereof equal to the fair market value as determined in the reasonable good faith judgment of the Board of such fractional interest as of the date of conversion.

(b) Subdivision or Combination of Common Stock. If the Corporation at any time subdivides (by any stock split, stock dividend or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the amount of Common Stock each holder of Class A-7 Preferred Shares is entitled to upon conversion shall be proportionately increased. Conversely, if the Corporation shall at any time or from time to time combine the outstanding shares of Common Stock into a smaller number of shares, the amount of

Common Stock each holder of Class A-7 Preferred Shares is entitled to upon conversion shall be proportionately decreased.

(c) Reorganization, Reclassification, Consolidation, Merger or Sale. Any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or substantially all of the Corporation’s assets or other transaction, in each case that is effected in such a manner that the holders of Common Stock are entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock, is referred to herein as an “Organic Change.” Prior to the consummation of any Organic Change, the Corporation shall make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least two-thirds of the Class A-7 Preferred Shares then outstanding) to insure that each of the holders of Class A-7 Preferred Shares shall thereafter have the right to acquire and receive, in lieu of or in addition to (as the case may be) the shares of Common Stock immediately theretofore acquirable and receivable upon the conversion of such holder’s Class A-7 Preferred Shares, such shares of stock, securities or assets as such holder would have received in connection with such Organic Change if such holder had converted its Class A-7 Preferred Shares immediately prior to such Organic Change. In each such case, the Corporation shall also make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least two-thirds of the Class A-7 Preferred Shares then outstanding) to insure that the provisions of this Section 8 hereof shall thereafter be applicable to the Class A-7 Preferred Shares (including, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is other than the Corporation, an immediate adjustment in the number of shares of Common Stock acquirable and receivable upon conversion of Class A-7 Preferred Shares, if the value per share of common stock so reflected is less than the value of the Common Stock (as reasonably determined by the Board) in effect immediately prior to such consolidation, merger or sale). The Corporation shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor entity (if other than the Corporation) resulting from consolidation or merger or the entity purchasing such assets assumes by written instrument (in form and substance satisfactory to the holders of at least two-thirds of the Class A-7 Preferred Shares 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.

(d) Mandatory Conversion. The Corporation may at any time require the conversion of all of the outstanding Class A-7 Preferred Shares upon the closing of a firmly underwritten public offering of shares of Common Stock.

Section 9. Registration of Transfer. The Corporation shall keep at its principal office a register for the registration of Class A-7 Preferred Shares. Upon the surrender of any certificate representing Class A-7 Preferred Shares at such place, the Corporation shall, at the request of the record holder of such certificate, execute and deliver (at the Corporation’s expense) a new certificate or certificates in exchange therefor representing in the aggregate the number of shares of Class A-7 Preferred Shares represented by the surrendered certificate. Each such new certificate shall be registered in such name and shall represent such number of shares of Class A-7 Preferred Shares as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Class A-7 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such Class A-7 Preferred Shares represented by the surrendered certificate.

Section 10. Replacement. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing Class A-7 Preferred Shares, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor its own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such Class A-7 Preferred Shares represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on the Class A-7 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate.

Section 11. Amendment and Waiver. No amendment, modification or waiver shall be binding or effective with respect to this paragraph (g) of this Article Sixth hereof without the prior written consent of the holders of at least two-thirds of the Class A-7 Preferred Shares outstanding at the time such action is taken and provided further that no change in the terms hereof may be accomplished by merger or consolidation of the Corporation with another corporation or entity unless the Corporation has obtained the prior written consent of the holders of at least the applicable percentage of the Class A-7 Preferred Shares then outstanding.

Section 12. Notices. Except as otherwise expressly provided hereunder, all notices, demands or other communications to be given or delivered under or by reason of the provisions of this paragraph (g) of this Article Sixth shall be in writing and shall be deemed to have been given when delivered personally to the recipient, sent to the recipient by reputable overnight courier service (charges prepaid), mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid, or transmitted by facsimile or electronic mail (with request for immediate confirmation of receipt in a manner customary for communications of such type and with physical delivery of the communication being made by one of the other means specified in this Section 12 as promptly as practicable thereafter).

If upon any such liquidation, dissolution or winding up of the Corporation, the Corporation’s assets to be distributed among the holders of the Class A Preferred Shares are insufficient to permit payment to such holders of the aggregate amount which they are entitled to be paid, then the entire assets available to be distributed to the Corporation’s Class A Preferred Shares stockholders shall be distributed pro rata among such holders based upon the aggregate Liquidation Amount of the Class A Preferred Shares held by each such holder.

The Class B-1 Preferred Shares shall rank (i) subordinate to the Class A Preferred Shares and the Class C Preferred Shares, (ii) pari passu with Class B-2 Convertible Preferred Stock and any other Class B Preferred Shares and (iii) prior to all of the shares of Junior Securities. In addition, so long as any Class B-1 Preferred Shares remain outstanding, without the prior written consent of the holders of two-thirds of the outstanding shares of Class B-1 Preferred Shares, the Corporation shall not, nor shall it permit any Subsidiary to, redeem, purchase or otherwise acquire directly or indirectly any Junior Securities; provided that the Corporation may purchase, redeem, acquire or retire for value shares of Junior Securities held by current or former directors or officers of the Company or any of its Subsidiaries upon death, disability, retirement, termination of employment or pursuant to the terms of any plan or other agreement under which such Junior Securities were issued to the extent permitted by the terms of the credit facility or facilities of the Corporation or its Subsidiaries.

Section 4. Dividends. Except with respect to dividends for which an adjustment is made pursuant to Section 8(d) hereof, the holders of Class B-1 Preferred Shares shall be entitled to participate, on an as converted basis, with the outstanding Common Stock as to any dividends payable on the Common Stock.

Section 5. Liquidation. Upon any liquidation, dissolution or winding up of the Corporation (whether voluntary or involuntary), each holder of Class B-1 Preferred Shares shall be entitled to be paid, before any distribution or payment is made upon any Junior Securities, an amount equal to the greater of (i) the aggregate Liquidation Value of all Class B-1 Preferred Shares held by such holder or (ii) the amount such holder of Class B-1 Preferred Shares would be entitled to receive if all Class B Preferred Shares were converted into Common Stock (the “Liquidation Amount”). All holders of Class B Preferred Shares shall be pari passu with respect to

their entitlement to receive their respective Liquidation Amounts. If upon any such liquidation, dissolution or winding up of the Corporation, the Corporation’s assets to be distributed among the holders of the Class B Preferred Shares are insufficient to permit payment to such holders of the aggregate amount which they are entitled to be paid under this Section 5, then the entire assets available to be distributed to the Corporation’s Class B Preferred Shares stockholders shall be distributed pro rata among such holders based upon the aggregate Liquidation Amount of the Class B Preferred Shares held by each such holder. Not less than sixty (60) days prior to the payment date stated therein, the Corporation shall mail written notice of any such liquidation, dissolution or winding up to each record holder of Class B Preferred Shares, setting forth in reasonable detail the amount of proceeds to be paid with respect to each Class B Preferred Share, Class A Preferred Share, Junior Security and each share of Common Stock in connection with such liquidation, dissolution or winding up.

Section 6. Voting Rights. The holders of the Class B Preferred Shares shall be entitled to notice of all stockholders meetings in accordance with the Corporation’s Bylaws, and except as otherwise required by applicable law, the holders of the Class B Preferred Shares shall not be entitled to vote.

Section 7. Special Consent Rights. The consent of the holders of at least two-thirds of the Class B-1 Preferred Shares, voting together as a single class, shall be required for any action that (a) authorizes or issues shares of any class of stock of a Junior Security having any preference or priority superior to any such preference or priority of the Class B-1 Preferred Shares; or (b) changes the number of shares or class of stock into which the Class B-1 Preferred Shares is convertible.

Section 8. Conversion or Redemption.

(a) Conversion Formula. Class B-1 Preferred Shares shall become convertible or redeemable in accordance with the following provisions:

(i) If the Benchmark IRR is greater than or equal to 55%, each share of Class B-1 Preferred Shares may be converted into 1.8 shares of Common Stock (which gives effect to the 0.8 for 1 stock dividend declared on the Common Stock on February 23, 2001).

(ii) If the Benchmark IRR is less than or equal to 35%, none of the shares of Class B-1 Preferred Shares may be converted.

(iii) If the Benchmark IRR is greater than 35% but less than 55%, a portion of the Class B-1 Preferred Shares may be converted into Common Stock. The number of shares of Class B-1 Preferred Shares held by each stockholder that may be converted into 1.8 shares of Common Stock for each such share of Class B-1 Preferred Shares (which gives effect to the 0.8 for 1 stock dividend declared on the Common Stock on February 23, 2001) shall be determined by the following formula:

1 minus

55 minus Benchmark IRR

Shares held by Holder

(iv) The “Benchmark IRR” shall mean either the 2002 Annual IRR, the 2004 Annual IRR, or the Liquidity Event IRR, whichever is the greatest.

(v) “The 2002 Annual IRR” shall mean the rate of return realized by the Corporation with respect to the value of one share of Class A-1 5% Convertible Preferred Stock based on a comparison of the Fair Market Value of one share of Class A-1 5% Convertible Preferred Stock on July 1, 2002 and the initial value of $10.94 of such stock on July 1, 1999.

(vi) “The 2004 Annual IRR” shall mean the rate of return realized by the Corporation with respect to the value of one share of Class A-1 5% Convertible Preferred Stock based on a comparison of the Fair Market Value of one share of Class A-1 5% Convertible Preferred Stock on July 1, 2004 and the initial value of $10.94 of such stock on July 1, 1999.

(vii) “The Liquidity Event IRR” shall mean the rate of return realized by the Corporation with respect to the value of one share of Class A-1 5% Convertible Preferred Stock based on a comparison of the Fair Market Value of one share of Class A-1 5% Convertible Preferred Stock 45 days before a Fundamental Change or a Public Offering and the initial value of $10.94 of such stock on July 1, 1999.

(viii) “Fair Market Value” shall be determined by an appraiser, familiar with the industry and companies similar to the Corporation, who shall be selected by the Board.

(ix) On July 1, 2002, on July 1, 2004, and 45 days before a Fundamental Change or a Public Offering, the “Fair Market Value” of one share of Class A-1 5% Convertible Preferred Stock and the Annual IRR shall be calculated by the Board.

(b) Conversion Procedure.

(i) Effective July 1, 2004, all of the Class B-1 Preferred Shares held by a stockholder shall be automatically converted pursuant to the provisions of Section 8(a), if not previously converted, into Common Stock without any further action by the holder of such shares and whether or not the certificates representing such shares are surrendered to the Corporation or its transfer agent; provided, however, that the Corporation shall not be obligated to issue certificates evidencing the shares of Common Stock issuable upon such conversion unless the certificates evidencing shares of Class B-1 Preferred Shares are either delivered to the Corporation or its transfer agent, or the holder notifies the Corporation or its transfer agent that such certificates have been lost, stolen or destroyed and executes an agreement satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection with such certificates. Upon surrender by any holder of the certificates formerly representing shares of the

Class B-1 Preferred Shares at the office of the Corporation or any transfer agent, there shall be issued and delivered to such holder promptly at such office and in its name as shown on such surrendered certificate or certificates, the certificate or certificates for the number of shares of Common Stock into which the shares of Class B-1 Preferred Shares surrendered or convertible on the date on which such automatic conversion occurred. Until surrendered, each certificate formerly representing shares of Class B-1 Preferred Shares shall be deemed for all corporate purposes to represent the number of shares of Common Stock resulting from such automatic conversion.

(ii) On or after July 1, 2002, any shares of Class B-1 Preferred Shares may, at the option of the holder, be converted at any time on or before July 1, 2004, into shares of Common Stock. The number of shares of Common Stock to which a holder of Class B-1 Preferred Shares shall be entitled upon conversion shall be determined pursuant to the provisions of Section 8(a). Each conversion of Class B-1 Preferred Shares shall be deemed to have been effected as of the close of business on the date on which the certificate or certificates representing the Class B-1 Preferred Shares to be converted have been surrendered for conversion at the principal office of the Corporation. At the time any such conversion has been effected, the rights of the holder of the shares converted as a holder of Class B-1 Preferred Shares shall cease and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the shares of Common Stock represented thereby.

(iii) In connection with a Public Offering or a Fundamental Change, any shares of Class B-1 Preferred Shares may, at the option of the holder, be converted into shares of Common Stock. The number of shares of Common Stock to which a holder of Class B-1 Preferred Shares shall be entitled upon conversion shall be determined pursuant to the provisions of Section 8(a). Notwithstanding any other provision hereof, if a conversion of Class B-1 Preferred Shares is to be made in connection with a Public Offering, a Change in Ownership, a Fundamental Change or other transaction affecting the Corporation, the conversion of any Class B-1 Preferred Shares may, at the election of the holder thereof, be conditioned upon the consummation of such transaction, in which case such conversion shall not be deemed to be effective until such transaction has been consummated.

(iv) The issuance of certificates for shares of Common Stock upon conversion of Class B-1 Preferred Shares shall be made without charge to the holders of such Class B-1 Preferred Shares for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such conversion and the related issuance of shares of Common Stock. Upon conversion of each Share of Class B-1 Preferred Shares, the Corporation shall take all such actions as are necessary in order to insure that the Common Stock issuable with respect to such conversion shall be validly issued, fully paid and nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the issuance thereof.

(v) The Corporation shall not close its books against the transfer of Class B-1 Preferred Shares or of Common Stock issued or issuable upon conversion of Class B-1 Preferred Shares in any manner which interferes with the timely conversion of

Class B-1 Preferred Shares. The Corporation shall assist and cooperate with any holder of shares of Class B-1 Preferred Shares required to make any governmental filings or obtain any governmental approval prior to or in connection with any conversion of Class B-1 Preferred Shares hereunder (including, without limitation, making any filings required to be made by the Corporation).

(vi) The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of issuance upon the conversion of the Class B-1 Preferred Shares, such number of shares of Common Stock issuable upon the conversion of all outstanding Class B-1 Preferred Shares. All shares of Common Stock which are so issuable shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. 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).

(vii) If any fractional interest in a share of Common Stock would, except for the provisions of this subparagraph, be delivered upon any conversion of the Class B-1 Preferred Shares, the Corporation, in lieu of delivering the fractional share therefor, shall pay an amount to the holder thereof equal to the fair market value as determined in the reasonable good faith judgment of the Board of such fractional interest as of the date of conversion.

(c) Redemption. On July 2, 2004 all of the outstanding Class B-1 Preferred Shares not converted into Common Stock pursuant to Section 8(b)(i) shall be redeemed at the Liquidation Value.

(d) Subdivision or Combination of Common Stock. If the Corporation at any time subdivides (by any stock split, stock dividend or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the amount of Common Stock each holder of Class B-1 Preferred Shares is entitled to upon conversion shall be proportionately increased. Conversely, if the Corporation shall at any time or from time to time combine the outstanding shares of Common Stock into a smaller number of shares, the amount of Common Stock each holder of Class B-1 Preferred Shares is entitled to upon conversion shall be proportionately decreased.

(e) Reorganization, Reclassification, Consolidation, Merger or Sale. Any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or substantially all of the Corporation’s assets or other transaction, in each case that is effected in such a manner that the holders of Common Stock are entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock, is referred to herein as an “Organic Change.” Prior to the consummation of any Organic Change, the Corporation shall make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least two-thirds of the Class B-1 Preferred Shares then outstanding)

to insure that each of the holders of Class B-1 Preferred Shares shall thereafter have the right to acquire and receive, in lieu of or in addition to (as the case may be) the shares of Common Stock immediately theretofore acquirable and receivable upon the conversion of such holder’s Class B-1 Preferred Shares, such shares of stock, securities or assets as such holder would have received in connection with such Organic Change if such holder had converted its Class B-1 Preferred Shares immediately prior to such Organic Change. In each such case, the Corporation shall also make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least 75% of the Class B-1 Preferred Shares then outstanding) to insure that the provisions of this Section 8 hereof shall thereafter be applicable to the Class B-1 Preferred Shares (including, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is other than the Corporation, an immediate adjustment in the number of shares of Common Stock acquirable and receivable upon conversion of Class B-1 Preferred Shares, if the value per share of common stock so reflected is less than the value of the Common Stock (as reasonably determined by the Board) in effect immediately prior to such consolidation, merger or sale). The Corporation shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor entity (if other than the Corporation) resulting from consolidation or merger or the entity purchasing such assets assumes by written instrument (in form and substance satisfactory to the holders of at least two-thirds of the Class B-1 Preferred Shares 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.

(f) Mandatory Conversion. The Corporation may at any time require the conversion of all of the outstanding Class B-1 Preferred Shares upon the closing of a firmly underwritten public offering of shares of Common Stock.

Section 9. Registration of Transfer. The Corporation shall keep at its principal office a register for the registration of Class B-1 Preferred Shares. Upon the surrender of any certificate representing Class B-1 Preferred Shares at such place, the Corporation shall, at the request of the record holder of such certificate, execute and deliver (at the Corporation’s expense) a new certificate or certificates in exchange therefor representing in the aggregate the number of shares of Class B-1 Preferred Shares represented by the surrendered certificate. Each such new certificate shall be registered in such name and shall represent such number of shares of Class B-1 Preferred Shares as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Class B-1 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such Class B-1 Preferred Shares represented by the surrendered certificate.

Section 10. Replacement. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing Class B-1 Preferred Shares, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor its own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such Class B-1 Preferred Shares represented by such lost, stolen, destroyed or mutilated certificate and dated the

date of such lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on the Class B-1 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate.

Section 11. Amendment and Waiver. No amendment, modification or waiver shall be binding or effective with respect to this paragraph (i) of this Article Sixth hereof without the prior written consent of the holders of at least two-thirds of the Class B-1 Preferred Shares outstanding at the time such action is taken and provided further that no change in the terms hereof may be accomplished by merger or consolidation of the Corporation with another corporation or entity unless the Corporation has obtained the prior written consent of the holders of at least the applicable percentage of the Class B-1 Preferred Shares then outstanding.

Section 12. Notices. Except as otherwise expressly provided hereunder, all notices, demands or other communications to be given or delivered under or by reason of the provisions of this paragraph (i) of this Article Sixth shall be in writing and shall be deemed to have been given when delivered personally to the recipient, sent to the recipient by reputable overnight courier service (charges prepaid), mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid, or transmitted by facsimile or electronic mail (with request for immediate confirmation of receipt in a manner customary for communications of such type and with physical delivery of the communication being made by one of the other means specified in this Section 12 as promptly as practicable thereafter). Such notices, demands and other communications shall be addressed (i) in the case of a holder of Class B-1 Preferred Shares, to his address as is designated in writing from time to time by such holder, (ii) in the case of the Corporation, to its principal office.

Upon surrender by any holder of the certificates formerly representing shares of the Class B-2 Preferred Shares at the office of the Corporation or any transfer agent, there shall be issued and delivered to such holder promptly at such office and in its name as shown on such surrendered certificate or certificates, the certificate or certificates for the number of shares of Common Stock into which the shares of Class B-2 Preferred Shares surrendered or convertible on the date on which such automatic conversion occurred. Until surrendered, each certificate formerly representing shares of Class B-2 Preferred Shares shall be deemed for all corporate purposes to represent the number of shares of Common Stock resulting from such automatic conversion.

(ii) On or after May 31, 2003, any shares of Class B-2 Preferred Shares may, at the option of the holder, be converted at any time on or before May 31, 2005, into shares of Common Stock. The number of shares of Common Stock to which a holder of Class B-2 Preferred Shares shall be entitled upon conversion shall be determined pursuant to the provisions of Section 8(a). Each conversion of Class B-2 Preferred Shares shall be deemed to have been effected as of the close of business on the date on which the certificate or certificates representing the Class B-2 Preferred Shares to be converted have been surrendered for conversion at the principal office of the Corporation.

(iii) In connection with a Public Offering or a Fundamental Change, any shares of Class B-2 Preferred Shares may, at the option of the holder, be converted into shares of Common Stock. The number of shares of Common Stock to which a holder of Class B-2 Preferred Shares shall be entitled upon conversion shall be determined pursuant to the provisions of Section 8(a). Notwithstanding any other provision hereof, if a conversion of Class B-2 Preferred Shares is to be made in connection with a Public Offering, a Change in Ownership, a Fundamental Change or other transaction affecting the Corporation, the conversion of any Class B-2 Preferred Shares may, at the election of the holder thereof, be conditioned upon the consummation of such transaction, in which case such conversion shall not be deemed to be effective until such transaction has been consummated.

Upon conversion of each Share of Class B-2 Preferred Shares, the Corporation shall take all such actions as are necessary in order to insure that the Common Stock issuable

with respect to such conversion shall be validly issued, fully paid and nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the issuance thereof.

(v) The Corporation shall not close its books against the transfer of Class B-2 Preferred Shares or of Common Stock issued or issuable upon conversion of Class B-2 Preferred Shares in any manner which interferes with the timely conversion of Class B-2 Preferred Shares. The Corporation shall assist and cooperate with any holder of shares of Class B-2 Preferred Shares required to make any governmental filings or obtain any governmental approval prior to or in connection with any conversion of Class B-2 Preferred Shares hereunder (including, without limitation, making any filings required to be made by the Corporation).

All shares of Common Stock which are so issuable shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. 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).

In each such case, the Corporation shall also make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least 75% of the Class B-2 Preferred Shares then outstanding) to insure that the provisions of this Section 8 hereof shall thereafter be applicable to the Class B-2 Preferred Shares (including, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is other than the Corporation, an immediate adjustment in the number of shares of Common Stock acquirable and receivable upon conversion of Class B-2 Preferred Shares, if the value per share of common stock so reflected is less than the value of the Common Stock (as reasonably determined by the Board) in effect immediately prior to such consolidation, merger or sale). The Corporation shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor entity (if other than the Corporation) resulting from consolidation or merger or the entity purchasing such assets assumes by written instrument (in form and substance satisfactory to the holders of at least two-thirds of the Class B-2 Preferred Shares 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.

Each such new certificate shall be registered in such name and shall represent such number of shares of Class B-2 Preferred Shares as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Class B-2 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such Class B-2 Preferred Shares represented by the surrendered certificate.

in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor its own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such Class B-2 Preferred Shares represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on the Class B-2 Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate.

(a) Conversion Procedure.

(i) At any time and from time to time, any holder of Class AA Preferred Shares may convert all or any portion of the Class AA Preferred Shares held by such holder into 1.8 shares of Common Stock per each share of Class AA Preferred Shares (which gives effect to the 0.8 for one stock dividend declared on the Common Stock on February 23, 2001).

(ii) Except as otherwise provided herein, each conversion of Class AA Preferred Shares shall be deemed to have been effected as of the close of business on the date on which the certificate or certificates representing the Class AA Preferred Shares to be converted have been surrendered for conversion at the principal office of the Corporation. At the time any such conversion has been effected, the rights of the holder of the shares converted as a holder of Class AA Preferred Shares shall cease and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the shares of Common Stock represented thereby.

(iii) Notwithstanding any other provision hereof, if a conversion of Class AA Preferred Shares is to be made in connection with a Public Offering, a Change in Ownership, a Fundamental Change or other transaction affecting the Corporation, the conversion of any Class AA Preferred Shares may, at the election of the holder thereof, be conditioned upon the consummation of such transaction, in which case such conversion shall not be deemed to be effective until such transaction has been consummated.

(B) payment of the amount payable under subparagraph (viii) below with respect to such conversion; and

(C) a certificate representing any Class AA Preferred Shares that were represented by the certificate or certificates delivered to the Corporation in connection with such conversion but that were not converted.

(v) The issuance of certificates for shares of Common Stock upon conversion of Class AA Preferred Shares shall be made without charge to the holders of such Class AA Preferred Shares for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such conversion and the related issuance of shares of Common Stock. Upon conversion of each share of Class AA Preferred Shares, the Corporation shall take all such actions as are necessary in order to insure that the Common Stock issuable with respect to

such conversion shall be validly issued, fully paid and nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the issuance thereof.

(vi) The Corporation shall not close its books against the transfer of Class AA Preferred Shares or of Common Stock issued or issuable upon conversion of Class AA Preferred Shares in any manner which interferes with the timely conversion of Class AA Preferred Shares. The Corporation shall assist and cooperate with any holder of Shares required to make any governmental filings or obtain any governmental approval prior to or in connection with any conversion of Class AA Preferred Shares hereunder (including, without limitation, making any filings required to be made by the Corporation).

(vii) The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of issuance upon the conversion of the Class AA Preferred Shares, such number of shares of Common Stock issuable upon the conversion of all outstanding Class AA Preferred Shares. All shares of Common Stock that are so issuable shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. 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).

(viii) If any fractional interest in a share of Common Stock would, except for the provisions of this subparagraph, be delivered upon any conversion of the Class AA Preferred Shares, the Corporation, in lieu of delivering the fractional share therefor, shall pay an amount to the holder thereof equal to the fair market value as determined in the reasonable good faith judgment of the Board of such fractional interest as of the date of conversion.

(b) Subdivision or Combination of Common Stock. If the Corporation at any time subdivides (by any stock split, stock dividend or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the amount of Common Stock each holder of Class AA Preferred Shares is entitled to upon conversion shall be proportionately increased. Conversely, if the Corporation shall at any time or from time to time combine the outstanding shares of Common Stock into a smaller number of shares, the amount of Common Stock each holder of Class AA Preferred Shares is entitled to upon conversion shall be proportionately decreased.

to insure that each of the holders of Class AA Preferred Shares shall thereafter have the right to acquire and receive, in lieu of or in addition to (as the case may be) the shares of Common Stock immediately theretofore acquirable and receivable upon the conversion of such holder’s Class AA Preferred Shares, such shares of stock, securities or assets as such holder would have received in connection with such Organic Change if such holder had converted its Class AA Preferred Shares immediately prior to such Organic Change. In each such case, the Corporation shall also make appropriate provisions (in form and substance reasonably satisfactory to the holders of at least two-thirds of the Class AA Preferred Shares then outstanding) to insure that the provisions of this Section 8 hereof shall thereafter be applicable to the Class AA Preferred Shares (including, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is other than the Corporation, an immediate adjustment in the number of shares of Common Stock acquirable and receivable upon conversion of Class AA Preferred Shares, if the value per share of common stock so reflected is less than the value of the Common Stock (as reasonably determined by the Board) in effect immediately prior to such consolidation, merger or sale). The Corporation shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor entity (if other than the Corporation) resulting from consolidation or merger or the entity purchasing such assets assumes by written instrument (in form and substance satisfactory to the holders of at least two-thirds of the Class AA Preferred Shares 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.

Upon the surrender of any certificate representing Class AA Preferred Shares at such place, the Corporation shall, at the request of the record holder of such certificate, execute and deliver (at the Corporation’s expense) a new certificate or certificates in exchange therefor representing in the aggregate the number of Shares represented by the surrendered certificate. Each such new certificate shall be registered in such name and shall represent such number of Shares as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Class AA Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such Class AA Preferred Shares represented by the surrendered certificate.

Section 10. Replacement. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing Class AA Preferred Shares, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor its own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such Class AA Preferred Shares represented by such lost, stolen, destroyed or mutilated certificate and dated the

date of such lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on the Class AA Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate.

Section 11. Amendment and Waiver. No amendment, modification or waiver shall be binding or effective with respect to this paragraph (k) of this Article Sixth hereof without the prior written consent of the holders of at least two-thirds of the Class AA Preferred Shares outstanding at the time such action is taken and provided further that no change in the terms hereof may be accomplished by merger or consolidation of the Corporation with another corporation or entity unless the Corporation has obtained the prior written consent of the holders of at least the applicable percentage of the Class AA Preferred Shares then outstanding.

(vi) The Corporation shall not close its books against the transfer of Class AB Preferred Shares or of Common Stock issued or issuable upon conversion of Class AB Preferred Shares in any manner which interferes with the timely conversion of Class AB Preferred Shares.

governmental filings or obtain any governmental approval prior to or in connection with any conversion of Class AB Preferred Shares hereunder (including, without limitation, making any filings required to be made by the Corporation).

(viii) If any fractional interest in a share of Common Stock would, except for the provisions of this subparagraph, be delivered upon any conversion of the Class AB Preferred Shares, the Corporation, in lieu of delivering the fractional share therefor, shall pay an amount to the holder thereof equal to the fair market value as determined in the reasonable good faith judgment of the Board of such fractional interest as of the date of conversion.

(b) Subdivision or Combination of Common Stock. If the Corporation at any time subdivides (by any stock split, stock dividend or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the amount of Common Stock each holder of Class AB Preferred Shares is entitled to upon conversion shall be proportionately increased. Conversely, if the Corporation shall at any time or from time to time combine the outstanding shares of Common Stock into a smaller number of shares, the amount of Common Stock each holder of Class AB Preferred Shares is entitled to upon conversion shall be proportionately decreased.

The Corporation shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor entity (if other than the Corporation) resulting from consolidation or merger or the entity purchasing such assets assumes by written instrument (in form and substance satisfactory to the holders of at least two-thirds of the Class AB Preferred Shares 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.

(d) Mandatory Conversion. The Corporation may at any time require the conversion of all of the outstanding Class AB Preferred Shares upon the closing of a firmly underwritten public offering of shares of Common Stock.

Upon the surrender of any certificate representing Class AB Preferred Shares at such place, the Corporation shall, at the request of the record holder of such certificate, execute and deliver (at the Corporation’s expense) a new certificate or certificates in exchange therefor representing in the aggregate the number of Shares represented by the surrendered certificate. Each such new certificate shall be registered in such name and shall represent such number of Shares as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Class AB Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such Class AB Preferred Shares represented by the surrendered certificate.

Section 10. Replacement. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing Class AB Preferred Shares, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor its own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such Class AB Preferred Shares represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on the Class AB Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate.

Section 2. Designation; Shares Authorized. 1,200,000 of the shares of preferred stock are hereby designated Class C Redeemable Preferred Stock (“Class C Preferred Shares”). Such number of shares may be decreased by resolution of the Board adopted and filed pursuant to applicable law; provided, that no such decrease shall reduce the number of authorized Class C Preferred Shares to a number less than the number of shares then outstanding plus the number of shares reserved for issuance upon the exercise of outstanding options, warrants, convertible or exchangeable securities or other rights to acquire Class C Preferred Shares.

Section 3. Priority. The Class C Preferred Shares shall rank prior to all of the shares of Junior Securities.

All holders of Class C Preferred Shares shall be pari passu with respect to their entitlement to receive dividends. The date on which any share of Class C Preferred Shares is initially issued by the Corporation (or its predecessor) shall be deemed to be its “date of issuance” regardless of the number of times transfer of such share is made on the stock records maintained by or for the Corporation and regardless of the number of certificates which may be issued to evidence such share. Each certificate shall have a legend indicating the “date of issuance” for purposes of the dividend calculation referred to herein. Except as otherwise provided herein, if at any time the Corporation pays less than the total amount of dividends then accrued with respect to the Class C Preferred Shares, such payment shall be distributed pro rata among the holders thereof based upon the number of Class C Preferred Shares held by each such holder.

Section 5. Liquidation. Upon any liquidation, dissolution or winding up of the Corporation (whether voluntary or involuntary), each holder of Class C Preferred Shares shall be entitled to be paid, before any distribution or payment is made upon any Junior Securities, an amount equal to the aggregate Liquidation Value of all Class C Preferred Shares held by such holder plus all accumulated but unpaid dividends (collectively, the “Liquidation Amount”). All

holders of Class C Preferred Shares shall be pari passu with respect to their entitlement to receive their respective Liquidation Amounts. If upon any such liquidation, dissolution or winding up of the Corporation, the Corporation’s assets to be distributed among the holders of the Class C Preferred Shares are insufficient to permit payment to such holders of the aggregate amount which they are entitled to be paid, then the entire assets available to be distributed to the Corporation’s stockholders shall be distributed pro rata among such holders based upon the aggregate Liquidation Amount of the Class C Preferred Shares held by each such holder. Not less than sixty (60) days prior to the payment date stated therein, the Corporation shall mail written notice of any such liquidation, dissolution or winding up to each record holder of Class C Preferred Shares, setting forth in reasonable detail the amount of proceeds to be paid with respect to each Class C Preferred Share, Junior Security and each share of Common Stock in connection with such liquidation, dissolution or winding up.

Section 6. Voting Rights. The holders of the Class C Preferred Shares shall be entitled to notice of all stockholders meetings in accordance with the Corporation’s Bylaws, but except as otherwise required by these Articles or by applicable law, the holders of the Class C Preferred Shares shall not be entitled to vote.

Section 7. Special Voting Rights. The consent of the holders of a majority of the Class C Preferred Shares, voting together as a single class, shall be required for any action that authorizes or issues shares of any class of stock pari passu or having any preference or priority with respect to liquidation or dividends superior to any such preference or priority of the Class C Preferred Shares (which shall not include the authorization or issuance of any Subsequent Class A Shares or Subsequent Class B Shares).

Section 8. Redemption.

(a) Redemption Procedure. Upon the closing of a firmly underwritten Public Offering or a Sale of the Business, all of the Class C Preferred Shares held by a shareholder shall be immediately redeemed, if not previously redeemed, at the Liquidation Amount, without any further action by the holder of such shares and whether or not the certificates representing such shares are surrendered to the Corporation or its transfer agent. Notwithstanding anything to the contrary contained herein, no Class C Preferred Shares shall be redeemed if such redemption would result in the violation of the terms or provisions of any credit facility or loan agreement of the Corporation or its Subsidiaries.

(b) Redemption Payments. For each Class C Preferred Share which is to be redeemed hereunder, the Corporation shall be obligated on the Redemption Date to pay to the holder thereof (upon surrender by such holder at the Corporation’s principal office of the certificate representing such Class C Preferred Share) an amount equal to the Liquidation Value of such Class C Preferred Share (plus all accumulated and unpaid dividends thereon). If the funds of the Corporation legally available for redemption of Class C Preferred Shares on any Redemption Date are insufficient to redeem the total number of Class C Preferred Shares to be redeemed on such date, those funds which are legally available shall be used to redeem the maximum possible number of Class C Preferred Shares pro rata among the holders of the Class C Preferred Shares to be redeemed based upon the aggregate Liquidation Value of such Class C Preferred Shares held by each such holder. At any time thereafter when additional funds of the Corporation are legally

available for the redemption of Class C Preferred Shares, such funds shall immediately be used to redeem the balance of the Class C Preferred Shares which the Corporation has become obligated to redeem on any Redemption Date but which it has not redeemed. In case fewer than the total number of Class C Preferred Shares represented by any certificate are redeemed, a new certificate representing the number of unredeemed Class C Preferred Shares shall be issued to the holder thereof without cost to such holder within three business days after surrender of the of the certificate representing the redeemed Class C Preferred Shares.

(c) Dividends After Redemption Date. No Class C Preferred Share shall be entitled to any dividends accruing after the date on which the Liquidation Value (plus all accumulated and unpaid dividends thereon) of such Class C Preferred Share is paid to the holder of such Class C Preferred Share. On such date, all rights of the holder of such Class C Preferred Share shall cease, and such Class C Preferred Share shall no longer be deemed to be issued and outstanding.

(d) Redeemed or Otherwise Acquired Class C Preferred Shares. Any Class C Preferred Shares which are redeemed or otherwise acquired by the Corporation shall be cancelled and retired to authorized but unissued shares and shall not be reissued, sold or transferred.

Section 9. Registration of Transfer. The Corporation shall keep at its principal office a register for the registration of Class C Preferred Shares.

Each such new certificate shall be registered in such name and shall represent such number of Shares as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Class C Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such Class C Preferred Shares represented by the surrendered certificate.

Section 10. Replacement. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing Class C Preferred Shares, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor its own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such Class C Preferred Shares represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on the Class C Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate.

Section 11. Amendment and Waiver. No amendment, modification or waiver shall be binding or effective with respect to this paragraph (m) of this Article Sixth hereof without

the prior written consent of the holders of a majority of the Class C Preferred Shares outstanding at the time such action is taken.

Section 12. Notices.
