ITEM 5. OTHER EVENTS. On August 11, 2000, Casella Waste Systems, Inc. (the "Company") completed the sale of 55,750 shares of its Series A Convertible Preferred Stock ("the "Series A Preferred Stock") for approximately $55.8 million. The Company sold the Series A Preferred Stock pursuant to that certain Preferred Stock Purchase Agreement, dated as of June 28, 2000, by and among the Company and the Purchasers identified therein (the "Agreement"). Each share of Series A Preferred Stock issued in the transaction is convertible, at any time and from time to time, into shares of the Company's Class A Common Stock, at an initial conversion price of $14 per share. The conversion price is subject to adjustment if the Company (i) subdivides its common stock by effecting a stock split or stock dividend, or (ii) subject to certain exceptions, issues or sells additional shares of common stock or securities convertible into common stock for less than $14 per share. The Series A Preferred Stock accrues preferential dividends daily and on a cumulative basis at an annual rate of five percent (5%) of its liquidation value, as defined in the Agreement, payable quarterly in arrears in additional shares of Series A Preferred Stock through August 11, 2003 and thereafter, at the option of the Company, in either cash or additional shares of Series A Preferred Stock. At any time on or after the occurrence of a change of control and for a period of 30 days thereafter, holders of Series A Preferred Stock will have the right to require the Company to redeem all or a portion of their stock at a redemption price equal to its liquidation value. All outstanding shares of Series A Preferred Stock are subject to mandatory redemption by the Company on August 11, 2007 pursuant to the terms of the Agreement. The Purchasers are entitled to nominate one person who shall be included among the Company's nominees for election to the Board of Directors as the Purchaser Director for so long as they hold at least 20% of the Class A Common Stock issued or issuable upon conversion of the Preferred Shares (the "Underlying Common Stock") and, so long as they own at least 20% of the Preferred Shares, the Purchasers shall have the right to designate one person to serve as Purchaser Observer. The holders of the Preferred Shares also are entitled to vote, as a class, with holders of common stock on each matter submitted to a vote of the Company's stockholders. Each share of Series A Convertible Preferred Stock has a number of votes equal to the number of shares of Class A Common Stock issuable upon conversion of a share of Series A Convertible Preferred Stock. Pursuant to the terms of the Agreement, the Company filed a Certificate of Designation with the Secretary of State of Delaware, creating the Series A Convertible Preferred Stock. This Current Report on Form 8-K is being filed for the purpose of filing as exhibits the Agreement, the Certificate of Designation, a Registration Rights Agreement, dated August 11, 2000, by and among the Company and the Purchasers, the Second Amended and Restated By-Laws of the Company, as amended to date, and certain amendments to that Amended and Restated Revolving Credit and Term Loan Agreement, dated January 12, 1998, between the Company and Fleet National Bank (f/k/a BankBoston, N.A.).

BY-LAWS OF CASELLA WASTE SYSTEMS, INC. ARTICLE 1 - Stockholders 1.1 Place of Meetings. All meetings of stockholders shall be held at such place within or without the State of Delaware as may be designated from time to time by the Board of Directors or the President or, if not so designated, at the registered office of the corporation. 1.2 Annual Meeting. The annual meeting of stockholders for the election of directors and for the transaction of such other business as may properly be brought before the meeting shall be held on a date to be fixed by the Board of Directors or the President (which date shall not be a legal holiday in the place where the meeting is to be held) at the time and place to be fixed by the Board of Directors or the President and stated in the notice of the meeting. If no annual meeting is held in accordance with the foregoing provisions, the Board of Directors shall cause the meeting to be held as soon thereafter as convenient. If no annual meeting is held in accordance with the foregoing provisions, a special meeting may be held in lieu of the annual meeting, and any action taken at that special meeting shall have the same effect as if it had been taken at the annual meeting, and in such case all references in these By-laws to the annual meeting of the stockholders shall be deemed to refer to such special meeting. 1.3 Special Meetings. Special meetings of stockholders may be called at any time by the President or by the Chairman of the Board. Business transacted at any special meeting of stockholders shall be limited to matters relating to the purpose or purposes stated in the notice of meeting. 1.4 Notice of Meetings. Except as otherwise provided by law, written notice of each meeting of stockholders, whether annual or special, shall be given not less than 10 nor more than 60 days before the date of the meeting to each stockholder entitled to vote at such meeting. The notices of all meetings shall state the place, date and hour of the meeting. The notice of a special meeting shall state, in addition, the purpose or purposes for which the meeting is called. If mailed, notice is given when deposited in the United States mail, postage prepaid, directed to the stockholder at his address as it appears on the records of the corporation.

1.5 Voting List. The officer who has charge of the stock ledger of the corporation shall prepare, at least 10 days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least 10 days prior to the meeting, at a place within the city where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time of the meeting, and may be inspected by any stockholder who is present. 1.6 Quorum. Except as otherwise provided by law, the Certificate of Incorporation or these By-laws, the holders of shares representing a majority of the votes entitled to be cast on matters other than the election of the Class A Director, present in person or represented by proxy, shall constitute a quorum for the transaction of business; provided, however, that a quorum shall only be deemed to be present for purposes of the election of the Class A Director if the holders of shares representing a majority of the votes entitled to be cast by the holders of the Class A Common Stock are present or represented by proxy. 1.7 Adjournments. Any meeting of stockholders may be adjourned to any other time and to any other place at which a meeting of stockholders may be held under these By-laws by the stockholders present or represented at the meeting and entitled to vote, although less than a quorum, or, if no stockholder is present, by any officer entitled to preside at or to act as Secretary of such meeting. It shall not be necessary to notify any stockholder of any adjournment of less than 30 days if the time and place of the adjourned meeting are announced at the meeting at which adjournment is taken, unless after the adjournment a new record date is fixed for the adjourned meeting. At the adjourned meeting, the corporation may transact any business which might have been transacted at the original meeting. 1.8 Voting and Proxies. Each stockholder shall have one vote for each share of stock entitled to vote held of record by such stockholder and a proportionate vote for each fractional share so held, unless otherwise provided in the Certificate of Incorporation. Each stockholder of record entitled to vote at a meeting of stockholders, or to express consent or dissent to corporate action in writing without a meeting, may vote or express such consent or dissent in person or may authorize another person or persons to vote or act for him by written proxy executed by the stockholder or his authorized agent and delivered to the Secretary of the corporation. No such proxy shall be voted or acted upon after three years from the date of its execution, unless the proxy expressly provides for a longer period. 1.9 Action at Meeting. When a quorum is present at any meeting, the holders of shares of stock representing a majority of the votes cast on a matter (or if -2-

there are two or more classes of stock entitled to vote as separate classes, then in the case of each such class, the holders of shares of stock of that class representing a majority of the votes cast on a matter) shall decide any matter to be voted upon by the stockholders at such meeting, except when a different vote is required by express provision of law, the Certificate of Incorporation or these By-Laws. Except as otherwise provided by these By-laws, when a quorum is present at any meeting, any election by stockholders shall be determined by a plurality of the votes cast on the election. 1.10 Introduction of Business at Meeting. Except as otherwise provided by law, at any annual or special meeting of stockholders only such business shall be conducted as shall have been properly brought before the meeting. In order to be properly brought before the meeting, such business must have been either (A) specified in the written notice of the meeting (or any supplement thereto) given to stockholders of record on the record date for such meeting by or at the direction of the Board of Directors, (B) brought before the meeting at the direction of the Board of Directors or the chairman of the meeting or (C) specified in a written notice given by or on behalf of a stockholder of record on the record date for such meeting entitled to vote thereat or a duly authorized proxy for such stockholder, in accordance with all of the following requirements. A notice referred to in clause (C) hereof must be delivered personally to or mailed to and received at the principal executive office of the corporation, addressed to the attention of the Secretary, not more than ten (10) days after the date of the initial notice referred to in clause (A) hereof, in the case of business to be brought before a special meeting of stockholders, and not less than thirty (30) days prior to the first anniversary date of the initial notice referred to in clause (A) hereof to the previous year's annual meeting, in the case of business to be brought before an annual meeting of stockholders. Such notice referred to in clause (C) hereof shall set forth (i) a full description of each such item of business proposed to be brought before the meeting, (ii) the name and address of the person proposing to bring such business before the meeting, (iii) the class and number of shares held of record, held beneficially and represented by proxy by such person as of the record date for meeting (if such date has been made publicly available) and as of the date of such notice, (iv) if any item of such business involves nomination for director, all information regarding each such nominee that would be required to be set forth in a definitive proxy statement filed with the Securities and Exchange Commission pursuant to Section 14 of the Securities Act of 1934, as amended, or any successor thereto, and the written consent of each such nominee to serve if elected, and (v) all other information that would be required to be filed with the Securities and Exchange Commission if, with respect to the business proposed to be brought before the meeting, the person proposing such business was a participant in a solicitation subject to Section 14 of the Securities Exchange Act of 1934, as amended, or any successor thereto. No business shall be brought before any meeting of stockholders of the Corporation otherwise than as provided in this paragraph. -3-

Nothing in the foregoing provisions shall obligate the corporation or the Board of Directors to include information as to any nominee for director submitted by a stockholder in any proxy statement or other communication sent to stockholders. The chairman of the meeting may, if the facts warrant, determine and declare to the meeting that any proposed item of business was not brought before the meeting in accordance with the foregoing procedure and, if he should so determine, he shall so declare to the meeting and the defective item of business shall be disregarded. 1.11 Action without Meeting. Stockholders of the corporation may not take any action by written consent in lieu of a meeting. ARTICLE 2 - Directors 2.1 General Powers. The business and affairs of the corporation shall be managed by or under the direction of a Board of Directors, who may exercise all of the powers of the corporation except as otherwise provided by law or the Certificate of Incorporation. In the event of a vacancy in the Board of Directors, the remaining directors, except as otherwise provided by law, may exercise the powers of the full Board until the vacancy is filled. 2.2 Number of Directors. The number of directors which shall constitute the whole Board of Directors shall be determined by resolution of a majority of the Board of Directors, but in no event shall be less than three. The number of directors may be decreased at any time and from time to time by a majority of the directors then in office, but only to eliminate vacancies existing by reason of the death, resignation, removal or expiration of the term of one or more directors. The directors shall be elected at the annual meeting of the stockholders by such stockholders as have the right to vote on such election. Directors need not be stockholders of the corporation. 2.3 Classes of Directors. The Board of Directors shall be and is divided into three classes: Class I, Class II and Class III. No one class shall have more than one director more than any other class. If a fraction is contained in the quotient arrived at by dividing the authorized number of directors by three, then, if such fraction is one-third, the extra director shall be a member of Class I and, if such fraction is two-thirds, one of the extra directors shall be a member of Class I and the other extra director shall be a member of Class II, unless otherwise provided for from time to time by resolution adopted by a majority of the Board of Directors. The Class A Director shall be in Class I. -4-

2.4 Election of Directors. The holders of Class A Common Stock, voting separately as a class, shall be entitled to elect one director (the "Class A Director"). All other directors shall be elected by the holders of the Class A Common Stock and Class B Common Stock, if any, voting together as a single class. 2.5 Terms of Office. Each director shall serve for a term ending on the date of the third annual meeting following the annual meeting at which such director was elected; provided, however, that each initial director in Class I shall serve for a term ending on the date of the annual meeting next following the end of the Corporation's fiscal year ending April 30, 1998; each initial director in Class II shall serve for a term ending on the date of the annual meeting next following the end of the Corporation's fiscal year ending April 30, 1999; and each initial director in Class III shall serve for a term ending on the date of the annual meeting next following the end of the Corporation's fiscal year ending April 30, 2000. 2.6 Allocation of Directors Among Classes in the Event of Increases or Decreases in the Number of Directors. In the event of any increase or decrease in the authorized number of directors, (i) each director then serving as such shall nevertheless continue as director of the class of which he is a member until the expiration of his current term or his prior death, retirement or resignation and (ii) the newly created or eliminated directorships resulting from such increase or decrease shall be apportioned by the Board of Directors among the three classes of directors so as to ensure that no one class has more than one director more than any other class. To the extent possible, consistent with the foregoing rule, any newly created directorships shall be added to those classes whose terms of office are to expire at the latest dates following such allocation, and any newly eliminated directorships shall be subtracted from those classes whose terms of office are to expire at the earliest dates following such allocation, unless otherwise provided for from time to time by resolution adopted by a majority of the directors then in office, although less than a quorum. 2.7 Tenure. Notwithstanding any provisions to the contrary contained herein, each director shall hold office until his successor is elected and qualified, or until his earlier death, resignation or removal. 2.8 Vacancies. Any vacancy in the Board of Directors, however occurring, including a vacancy resulting from an enlargement of the Board, may be filled only by vote of a majority of the directors then in office, although less than a quorum, or by a sole remaining director. A director elected to fill a vacancy shall be elected for the unexpired term of his predecessor in office, if applicable, and a director chosen to fill a position resulting from an increase in the number of directors shall hold office until the next election of the class for which such director shall have been chosen and until his successor is elected and qualified, or until his earlier death, resignation or removal. -5-

2.9 Quorum. A majority of the total number of the whole Board of Directors shall constitute a quorum at all meetings of the Board of Directors. In the event one or more of the directors shall be disqualified to vote at any meeting, then the required quorum shall be reduced by one for each such director so disqualified; provided, however, that in no case shall less than one-third (1/3) of the number so fixed constitute a quorum. In the absence of a quorum at any such meeting, a majority of the directors present may adjourn the meeting from time to time without further notice other than announcement at the meting, until a quorum shall be present. 2.10 Action at Meeting. At any meeting of the Board of Directors at which a quorum is present, the vote of a majority of those present shall be sufficient to take any action, unless a different vote is specified by law or the Certificate of Incorporation or these By-Laws. 2.11 Removal. Any one or more or all of the directors may be removed, with or without cause, by the holders of shares representing at least seventy-five percent (75%) of the votes which all the stockholders would be entitled to cast at any election of directors or class of directors (other than an election of the Class A Director); provided, however, that the Class A Director may be removed only by the holders of at least seventy-five percent (75%) of the outstanding shares of Class A Common Stock. 2.12 Resignation. Any director may resign by delivering his written resignation to the corporation at its principal office or to the President or Secretary. Such resignation shall be effective upon receipt unless it is specified to be effective at some other time or upon the happening of some other event. 2.13 Regular Meetings. Regular meetings of the Board of Directors may be held without notice at such time and place, either within or without the State of Delaware, as shall be determined from time to time by the Board of Directors; provided that any director who is absent when such a determination is made shall be given notice of the determination. A regular meeting of the Board of Directors may be held without notice immediately after and at the same place as the annual meeting of stockholders. 2.14 Special Meetings. Special meetings of the Board of Directors may be held at any time and place, within or without the State of Delaware, designated in a call by the Chairman of the Board, President, two or more directors, or by one director in the event that there is only a single director in office. 2.15 Notice of Special Meetings. Notice of any special meeting of directors shall be given to each director by the Secretary or by the officer or one of the -6-

directors calling the meeting. Notice shall be duly given to each director (i) by giving notice to such director in person or by telephone at least 48 hours in advance of the meeting, (ii) by sending a telegram or telex, or delivering written notice by hand, to his last known business or home address at least 48 hours in advance of the meeting, or (iii) by mailing written notice to his last known business or home address at least 72 hours in advance of the meeting. A notice or waiver of notice of a meeting of the Board of Directors need not specify the purposes of the meeting. 2.16 Meetings by Telephone Conference Calls. Directors or any members of any committee designated by the directors may participate in a meeting of the Board of Directors or such committee by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation by such means shall constitute presence in person at such meeting. 2.17 Action by Consent. Any action required or permitted to be taken at any meeting of the Board of Directors or of any committee of the Board of Directors may be taken without a meeting, if all members of the Board or committee, as the case may be, consent to the action in writing, and the written consents are filed with the minutes of proceedings of the Board or committee. 2.18 Committees. The Board of Directors may designate one or more committees, each committee to consist of one or more of the directors of the corporation. The Board may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence or disqualification of a member of a committee, the member or members of the committee present at any meeting and not disqualified from voting, whether or not he or they constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in the place of any such absent or disqualified member. Any such committee, to the extent provided in the resolution of the Board of Directors and subject to the provisions of the General Corporation Law of the State of Delaware, shall have and may exercise all the powers and authority of the Board of Directors in the management of the business and affairs of the corporation and may authorize the seal of the corporation to be affixed to all papers which may require it. Each such committee shall keep minutes and make such reports as the Board of Directors may from time to time request. Except as the Board of Directors may otherwise determine, any committee may make rules for the conduct of its business, but unless otherwise provided by the directors or in such rules, its business shall be conducted as nearly as possible in the same manner as is provided in these By-laws for the Board of Directors. 2.19 Compensation of Directors. Directors may be paid such compensation for their services and such reimbursement for expenses of attendance at meetings as the Board of Directors may from time to time determine. No such payment shall -7-

preclude any director from serving the corporation or any of its parent or subsidiary corporations in any other capacity and receiving compensation for such service. ARTICLE 3 - Officers 3.1 Enumeration. The officers of the corporation shall consist of a President, a Secretary, a Treasurer and such other officers with such other titles as the Board of Directors shall determine, including a Chairman of the Board, a Vice-Chairman of the Board, and one or more Vice Presidents, Assistant Treasurers, and Assistant Secretaries. The Board of Directors may appoint such other officers as it may deem appropriate. 3.2 Election. The President, Treasurer and Secretary shall be elected annually by the Board of Directors at its first meeting following the annual meeting of stockholders. Other officers may be appointed by the Board of Directors at such meeting or at any other meeting. 3.3 Qualification. No officer need be a stockholder. Any two or more offices may be held by the same person. 3.4 Tenure.

Any officer may resign by delivering his written resignation to the corporation at its principal office or to the President or Secretary. Such resignation shall be effective upon receipt unless it is specified to be effective at some other time or upon the happening of some other event. Any officer may be removed at any time, with or without cause, by vote of a majority of the entire number of directors then in office. Except as the Board of Directors may otherwise determine, no officer who resigns or is removed shall have any right to any compensation as an officer for any period following his resignation or removal, or any right to damages on account of such removal, whether his compensation be by the month or by the year or otherwise, unless such compensation is expressly provided in a duly authorized written agreement with the corporation. 3.6 Vacancies.

Notwithstanding any other provision of law, the Certificate of Incorporation or these By-Laws (including the preceding paragraph), and notwithstanding the fact that a lesser percentage may be specified by law, the affirmative vote of the holders of shares representing at least 75% of the votes which all the stockholders would be entitled to cast at any election of directors or class of directors (other than an election of the Class A Director) shall be required to amend or repeal, or to adopt any provision inconsistent with, the provisions of Sections 1.10 or 1.11, the provisions of Article II, or the provisions of this Section 6.2. -14-

Exhibit 4.1 Certificate of Designation of Rights, Preferences and Limitations of Series A Convertible Preferred Stock of Casella Waste Systems, Inc. Casella Waste Systems, Inc., a Delaware corporation (the "Corporation"), pursuant to authority conferred on the Board of Directors of the Corporation by the Certificate of Incorporation and in accordance with the provisions of Section 151 of the General Corporation Law of the State of Delaware, certifies that the Board of Directors of the Corporation, at a meeting duly called and held, at which a quorum was present and acting throughout, duly adopted the following resolution: RESOLVED: That, pursuant to the authority expressly granted to and vested in the Board of Directors of the Corporation in accordance with the provisions of its Certificate of Incorporation, a series of Preferred Stock of the Corporation be and hereby is established, consisting of 55,750 shares, to be designated "Series A Convertible Preferred Stock" (hereinafter "Series A Preferred Stock"); that the Board of Directors be and hereby is authorized to issue such shares of Series A Preferred Stock from time to time and for such consideration and on such terms as the Board of Directors shall determine; and that, subject to the limitations provided by law and by the Certificate of Incorporation, the powers, designations, preferences and relative, participating, optional or other special rights of, and the qualifications, limitations or restrictions upon, the Series A Preferred Stock shall be as follows: 1. Dividends. (a) Holders of the outstanding shares of Series A Preferred Stock will be entitled to receive dividends on each share of the Series A Preferred Stock, when and if declared by the Board of Directors, out of funds legally available therefor, at a rate per annum equal to 5.0% of the Liquidation Value, payable quarterly in arrears on January 31, April 30, July 31 and October 31 of each year (unless such day is not a business day, in which event such dividends shall be payable on the next succeeding business day) (each such date being a "Dividend Payment Date" and each such quarterly period being a "Dividend Period"), commencing on

October 31, 2000. Each such dividend shall be payable to the holders of record of shares of the Series A Preferred Stock as they appear on the stock register of the Corporation at the close of business on the corresponding Record Date. As used herein, the term "Record Date" means, with respect to the dividend payable on January 31, April 30, July 31 and October 31, respectively, of each year, the preceding January 15, April 15, July 15 and October 15, or such other date, not more than 60 days or less than 10 days preceding the payment dates thereof, as shall be fixed as the record date by the Board of Directors. Dividends, whether or not declared and whether or not there shall be earnings or surplus, will accrue on a daily basis and accumulate on the last day of each Dividend Period in accordance with the following sentence. If cash dividends are not declared by the Board of Directors and paid to the holders of the outstanding shares of Series A Preferred Stock on or before the respective Dividend Payment Date, such dividend shall accumulate by adding to the Accreted Value for each share of Series A Preferred Stock an amount equal to the Applicable Percentage multiplied by the Accreted Value as of the immediately preceding Dividend Payment Date. (b) Commencing on the third anniversary of the Closing Date, any dividend on the Series A Preferred Stock may, at the option of the Corporation, be paid in cash; provided, however, that, with respect to any Dividend Payment Date occurring prior to the third anniversary of the Closing Date, all such dividends shall not be declared or paid and the amount thereof shall accumulate as described in Section 1(a) above. As used herein, the "Applicable Percentage" for each full Dividend Period for the Series A Preferred Stock shall be 1.25%. The Applicable Percentage for the initial Dividend Period, or any other period shorter than a full period, shall be computed on the basis of a per annum rate of 5.0% and the actual number of days elapsed over a 365-day year. (c) If at any time after the fourth anniversary of the Closing Date, the average Market Price of the Class A Common Stock for a period of 30 consecutive trading days equals or exceeds $34.30 (subject to appropriate adjustments for stock splits, stock dividends, combinations and other similar recapitalizations after the Closing Date affecting the shares of the Common Stock), then the dividend on the Series A Preferred Stock shall cease to accrue; provided that the Corporation shall not have elected (or been required) to pay any dividend in cash pursuant to Section 1(b) prior to the fourth anniversary of the Closing Date. (d) All dividends paid with respect to shares of the Series A Preferred Stock shall be paid pro rata to the holders thereof entitled thereto. (e) If accrued dividends on the Series A Preferred Stock for all prior periods have not been (i) paid in full or (ii) added to the Accreted Value pursuant to Section 1(a), then any dividend declared on any Parity Stock or Junior Stock (other than the Common Stock) will be declared ratably on the Series A Preferred Stock in proportion to accrued and unpaid dividends on the Series A Preferred Stock and such Parity Stock or Junior Stock (other than the Common Stock) and if dividends on any Parity Stock or Junior Stock (other than the Common Stock) are due and payable and have not been paid in full, then any dividend declared on the Series A Preferred Stock will be declared ratably on the Parity Stock or Junior Stock (other than the Common Stock) in proportion to accrued and unpaid dividends on the Series A Preferred Stock and such Parity Stock or Junior Stock (other than the Common Stock). -2-

(f) So long as any shares of Series A Preferred Stock are outstanding, if the Corporation pays a dividend or distribution in cash on the Common Stock (other than dividends or distributions payable solely in Common Stock) then at the same time the Corporation shall declare and pay a dividend on each share of Series A Preferred Stock in the amount equal to the dividends that would be paid with respect to a share of Series A Preferred Stock if converted by the holder thereof into Common Stock on the date established as the record date with respect to such dividend on the Common Stock and there shall be no adjustment to the Series A Conversion Price with respect to such dividend. 2. Liquidation, Dissolution or Winding Up; Certain Mergers, Consolidations and Asset Sales. (a) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of shares of Series A Preferred Stock then outstanding shall be entitled to be paid out of the assets of the Corporation available for distribution to its stockholders, before any payment shall be made to the holders of Common Stock or any other class or series of stock ranking on liquidation junior to the Series A Preferred Stock (such Common Stock and other stock being collectively referred to as "Junior Stock") by reason of their ownership thereof, an amount equal to the greater of (i) the Liquidation Value, plus all accrued but unpaid dividends accrued but unpaid since the most recent Dividend Payment Date, or (ii) such amount per share as would have been payable had each such share been converted into Class A Common Stock pursuant to Section 4 immediately prior to such liquidation, dissolution or winding up. If upon any such liquidation, dissolution or winding up of the Corporation the remaining assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the holders of shares of Series A Preferred Stock and Parity Stock the full amount to which they shall be entitled, the holders of shares of Series A Preferred Stock and any Parity Stock shall share ratably in any distribution of the remaining assets and funds of the Corporation in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. (b) After the payment of all amounts required to be paid to the holders of Series A Preferred Stock and any Parity Stock in accordance with Section 2(a), upon the dissolution, liquidation or winding up of the Corporation, the holders of shares of Junior Stock then outstanding shall be entitled to receive the remaining assets and funds of the Corporation available for distribution to its stockholders. (c) Unless the holders of a majority of the shares of Series A Preferred Stock determine otherwise, any (i) merger or consolidation in which (A) the Corporation is a constituent party or (B) a subsidiary of the Corporation is a constituent party and the Corporation issues shares of its capital stock pursuant to such merger or consolidation (except any such merger or consolidation involving the Corporation or a subsidiary in which the holders of capital stock of the Corporation immediately prior to such merger or consolidation continue to hold immediately following such merger or consolidation at least 50% by voting power of the capital stock of (x) the surviving or resulting corporation or (y) if the surviving or resulting corporation is a wholly owned subsidiary of another corporation immediately following such merger or consolidation, the parent corporation of such surviving or resulting corporation), or (ii) the sale -3-

of all or substantially all the assets of the Corporation (other than a transfer of all or substantially all of the assets of the Corporation to one or more wholly owned subsidiaries), shall be deemed to be a liquidation of the Corporation for purposes of this Section 2, and the agreement or plan of merger or consolidation with respect to such merger, consolidation or sale shall provide that the consideration payable to the stockholders of the Corporation (in the case of a merger or consolidation), or consideration payable to the Corporation, together with all other available assets of the Corporation (in the case of an asset sale), shall be distributed to the holders of capital stock of the Corporation in accordance with Sections 2(a) and 2(b) above. The amount deemed distributed to the holders of Series A Preferred Stock upon any such merger, consolidation or sale shall be the cash or the value of the property, rights or securities distributed to such holders by the Corporation or the acquiring person, firm or other entity. The value of such property, rights or other securities shall be determined in good faith by the Board of Directors of the Corporation. For the purposes of this Section 2, except as expressly set forth in this Section 2(c), neither the sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property or assets of the Corporation nor the consolidation or merger of the Corporation with or into one or more other entities shall be deemed to be a liquidation, dissolution or winding-up of the Corporation. 3. Voting. (a) On any matter presented to the stockholders of the Corporation for their action or consideration at any meeting of stockholders of the Corporation, each holder of outstanding shares of Series A Preferred Stock shall be entitled to the number of votes equal to the number of whole shares of Class A Common Stock into which the shares of Series A Preferred Stock held by such holder are convertible as of the record date for determining stockholders entitled to vote on such matter. Except as provided by law, by the provisions of the Corporation's Certificate of Incorporation, by the provisions of Section 3(b) or Section 3(c) below or any other provision hereof specifically requiring the vote of the Series A Preferred Stock or by the provisions establishing any other series of Preferred Stock, holders of Series A Preferred Stock and of any other outstanding series of Preferred Stock shall vote together with the holders of Common Stock as a single class. (b) The Corporation shall not amend, alter or repeal the preferences, special rights or other powers of the Series A Preferred Stock or otherwise amend its Certificate of Incorporation (whether by amendment, merger, reorganization or otherwise) so as to affect adversely the Series A Preferred Stock, without the written consent or affirmative vote of the holders of a majority of the then outstanding shares of Series A Preferred Stock, given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a class. For this purpose, without limiting the generality of the foregoing, the authorization of any shares of capital stock with preference or priority over the Series A Preferred Stock as to the right to receive either dividends or amounts distributable upon liquidation, dissolution or winding up of the Corporation shall be deemed to affect adversely the Series A Preferred Stock, and subject to the provisions of Section 3(c), the authorization of any shares of capital stock on a parity or junior to with Series A Preferred Stock as to the right to receive either dividends or amounts distributable upon liquidation, dissolution or winding up of the Corporation shall not be deemed to affect adversely the Series A Preferred Stock. The number of authorized shares of Series A Preferred Stock may be increased or decreased (but not below the number of shares then -4-

outstanding) by the directors of the Corporation pursuant to Section 151 of the General Corporation Law of Delaware or by the affirmative vote of the holders of a majority of the votes entitled to be cast by the then outstanding shares of the Common Stock, Series A Preferred Stock and all other classes or series of stock of the Corporation entitled to vote thereon, voting as a single class, irrespective of the provisions of Section 242(b)(2) of the General Corporation Law of Delaware. (c) In addition to any other rights provided by law, so long as at least 15% of the initial number of shares of Series A Preferred Stock shall be outstanding, the Corporation shall not, without first obtaining the affirmative vote or written consent of the holders of not less than 50% of the then outstanding shares of Series A Preferred Stock: (i) issue any Parity Stock, Junior Stock (other than Common Stock) or convertible securities (other than stock options and other awards with respect to Common Stock given to employees, directors and consultants) ("Restricted Instruments") unless, in the opinion of counsel to the Corporation reasonably satisfactory to the holders of a majority of the shares of Series A Preferred Stock, (A) the issuance of such Restricted Instruments will not cause the Series A Preferred Stock to be treated as preferred stock for purposes of Section 305 of the Internal Revenue Code of 1986, as amended (the "Code"), and (B) regardless of whether the Corporation has or is expected to have current or accumulated earnings and profits, the terms of such Restricted Instruments will not permit or give rise to a distribution under Section 301 of the Code or a transaction treated as a distribution under Section 305(c) of the Code which will cause the holders of Series A Preferred Stock to realize income by reason of Section 305 of the Code; (ii) declare or pay any dividends or make any other direct or indirect distribution on account of any capital stock (other than Series A Preferred Stock or Common Stock); or (iii) redeem, repurchase, otherwise acquire or enter into any transaction involving the disposition of any shares of capital stock (other than a disposition of such shares by the Company) unless, in the opinion of counsel to the Corporation reasonably satisfactory to the holders of a majority of the shares of Series A Preferred Stock, regardless of whether the Corporation has or is expected to have current or accumulated earnings and profits, such transaction will not cause the holders Series A Preferred Stock to realize income by reason of Section 305 of the Code; provided however that this Section 3(c)(iii) shall not apply to repurchases by the Corporation of Common Stock on the open market in which the identity of the seller is unknown to the Corporation or to redemptions by the Corporation pursuant to Section 6 or Section 7. (d) Notwithstanding any other provision in the Corporation's Certificate of Incorporation or By-laws, the holders of the Series A Preferred Stock may take action by written consent in lieu of a meeting. 4. Optional Conversion. The holders of the Series A Preferred Stock shall have conversion rights as follows (the "Conversion Rights"): -5-

(a) Right to Convert. Each share of Series A Preferred Stock shall be convertible, at the option of the holder thereof, at any time and from time to time, and without the payment of additional consideration by the holder thereof, into fully paid and nonassessable shares of Class A Common Stock. The number of shares of Class A Common Stock deliverable upon conversion of a share of Series A Preferred Stock is determined by dividing the Liquidation Value on the applicable date plus all accrued but unpaid dividends which have not been added to the Accreted Value in accordance with Section 1(a) by the Series A Conversion Price (as defined below) in effect at the time of conversion. The "Series A Conversion Price" shall initially be $14.00. Such initial Series A Conversion Price, and the rate at which shares of Series A Preferred Stock may be converted into shares of Class A Common Stock, shall be subject to adjustment as provided below. In the event of a notice of redemption of any shares of Series A Preferred Stock pursuant to Section 6 hereof, the Conversion Rights of the shares designated for redemption shall terminate at the close of business on the first full day preceding the date fixed for redemption, unless the redemption price is not paid on such redemption date, in which case the Conversion Rights for such shares shall continue until such price is paid in full. In the event of a liquidation of the Corporation, the Conversion Rights shall terminate at the close of business on the first full day preceding the date fixed for the payment of any amounts distributable on liquidation to the holders of Series A Preferred Stock. (b) Fractional Shares. No fractional shares of Class A Common Stock shall be issued upon conversion of the Series A Preferred Stock. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the then effective Series A Conversion Price. (c) Mechanics of Conversion. (i) In order for a holder of Series A Preferred Stock to convert shares of Series A Preferred Stock into shares of Class A Common Stock, such holder shall surrender the certificate or certificates for such shares of Series A Preferred Stock, at the office of the transfer agent for the Series A Preferred Stock (or at the principal office of the Corporation if the Corporation serves as its own transfer agent), together with written notice that such holder elects to convert all or any portion of the shares of the Series A Preferred Stock represented by such certificate or certificates. Such notice shall state such holder's name or the names of the nominees in which such holder wishes the certificate or certificates for shares of Class A Common Stock to be issued. If required by the Corporation, certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or his or its attorney duly authorized in writing. The date of receipt of such certificates and notice by the transfer agent (or by the Corporation if the Corporation serves as its own transfer agent) shall be the conversion date ("Conversion Date"), and the shares of Class A Common Stock issuable upon conversion of the shares represented by such certificate shall be deemed to be outstanding of record as of such date. The Corporation shall, as soon as practicable after the Conversion Date, issue and deliver at such office to such holder of Series A Preferred Stock, or to his or its nominees, a certificate or certificates for the number of shares of Class A Common Stock to which such holder shall be entitled, together with cash in lieu of any fraction of a share. -6-

(ii) The Corporation shall at all times when the Series A Preferred Stock shall be outstanding, reserve and keep available out of its authorized but unissued stock, for the purpose of effecting the conversion of the Series A Preferred Stock, such number of its duly authorized shares of Class A Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding Series A Preferred Stock. Before taking any action which would cause an adjustment reducing the Series A Conversion Price below the then par value of the shares of Class A Common Stock issuable upon conversion of the Series A Preferred Stock, the Corporation will take any corporate action which may, in the opinion of its counsel, be necessary in order that the Corporation may validly and legally issue fully paid and nonassessable shares of Class A Common Stock at such adjusted Series A Conversion Price. (iii) All shares of Series A Preferred Stock which shall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares hereunder, including the rights, if any, to receive notices and to vote, shall immediately cease and terminate on the Conversion Date, except only the right of the holders thereof to receive shares of Class A Common Stock in exchange therefor and payment of any dividends declared but unpaid thereon. Any shares of Series A Preferred Stock so converted shall be retired and cancelled and shall not be reissued, and the Corporation (without the need for stockholder action) will take such appropriate action as may be necessary to reduce the authorized number of shares of Series A Preferred Stock accordingly. (iv) The Corporation shall pay any and all issue and other similar taxes that may be payable in respect of any issuance or delivery of shares of Class A Common Stock upon conversion of shares of Series A Preferred Stock pursuant to this Section 4. The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Class A Common Stock in a name other than that in which the shares of Series A Preferred Stock so converted were registered, and no such issuance or delivery shall be made unless and until the person or entity requesting such issuance has paid to the Corporation the amount of any such tax or has established, to the satisfaction of the Corporation, that such tax has been paid. (d) Adjustments to Series A Conversion Price for Diluting Issues: (i) Special Definitions. For purposes of this Section 4, the following definitions shall apply: (A) "Option" shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire Common Stock or Convertible Securities. (B) "Series A Original Issue Date" shall mean the date on which a share of Series A Preferred Stock was first issued. (C) "Convertible Securities" shall mean any evidences of indebtedness, shares or other securities directly or indirectly convertible into or exchangeable for Common Stock, but excluding Options. -7-

(D) "Additional Shares of Common Stock" shall mean all shares of Common Stock issued (or, pursuant to Subsection 4(d)(iii) below, deemed to be issued) by the Corporation after the Series A Original Issue Date, other than: (I) shares of Common Stock issued or issuable upon conversion or exchange of any Convertible Securities or exercise of any Options outstanding on the Series A Original Issue Date; (II) shares of Convertible Securities or Common Stock issued or issuable as a dividend or distribution on Series A Preferred Stock or the adjustment of the Series A Conversion Price; (III) shares of Common Stock issued or issuable by reason of a dividend, stock split, split-up or other distribution on shares of Common Stock that is covered by Section 4(e) or 4(f) below; (IV) shares of Common Stock (or Options with respect thereto) issued or issuable to employees or directors of, or consultants to, the Corporation pursuant to a plan or arrangement approved by the Board of Directors of the Corporation; or (V) shares of Convertible Securities or Common Stock (or Options with respect thereto) issued or issuable as consideration for the acquisition of a business or of assets (whether pursuant to a merger, asset acquisition or otherwise) or to the Corporation's joint venture partners in exchange for interests in the relevant joint venture, but only to the extent that the consideration per share (determined pursuant to Section 4(d)(v)) for such transactions consummated after the Closing Date is equal to or greater than $10.00 (subject to appropriate adjustments for stock splits, dividends, combinations and other similar recapitalizations after the Closing Date). (ii) No Adjustment of Series A Conversion Price. No adjustment in the Series A Conversion Price shall be made as the result of the issuance of Additional Shares of Common Stock if: (a) the consideration per share (determined pursuant to Subsection 4(d)(v)) for such Additional Share of Common Stock issued or deemed to be issued by the Corporation is equal to or greater than the applicable Series A Conversion Price in effect immediately prior to the issuance or deemed issuance of such Additional Shares, or (b) prior to such issuance or deemed issuance, the Corporation receives written notice from the holders of at least 50% of the -8-

then outstanding shares of Series A Preferred Stock agreeing that no such adjustment shall be made as the result of the issuance or deemed issuance of Additional Shares of Common Stock. (iii) Issue of Securities Deemed Issue of Additional Shares of Common Stock. If the Corporation at any time or from time to time after the Series A Original Issue Date shall issue any Options or Convertible Securities or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of shares of Common Stock (as set forth in the instrument relating thereto without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date (unless such Options or Convertible Securities are excluded from the definition of Additional Shares of Common Stock pursuant to Section 4(d)(I)(D) above), provided that (i) if those Options are only exercisable upon the occurrence of certain triggering events, then the Options will be deemed not to be issued or outstanding, and the Series A Conversion Price will not be adjusted with respect to such Options, until the triggering events occur, and (ii) Additional Shares of Common Stock shall not be deemed to have been issued unless the consideration per share (determined pursuant to Section 4(d)(v) hereof) of such Additional Shares of Common Stock would be less than the applicable Series A Conversion Price in effect on the date of and immediately prior to such issue, or such record date, as the case may be, and provided further that in any such case in which Additional Shares of Common Stock are deemed to be issued: (A) No further adjustment in the Series A Conversion Price shall be made upon the subsequent issue of Convertible Securities or shares of Common Stock upon the exercise of such Options or conversion or exchange of such Convertible Securities; (B) If such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any increase or decrease in the consideration payable to the Corporation, upon the exercise, conversion or exchange thereof, the Series A Conversion Price computed upon the original issue thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective, be recomputed to reflect such increase or decrease insofar as it affects such Options or the rights of conversion or exchange under such Convertible Securities; (C) Upon the expiration or termination of any such unexercised Option or unconverted Convertible Security, the Series A Conversion Price shall not be readjusted, but the Additional Shares of Common Stock deemed issued as the result of the original issue of such Option or Convertible Security shall not be deemed issued for the purposes of any subsequent adjustment of the Series A Conversion Price; (D) In the event of any change in the number of shares of Common Stock issuable upon the exercise, conversion or exchange of any such Option or Convertible Security, including, but not limited to, a change resulting from the anti-dilution provisions thereof, the Series A Conversion Price then in effect shall forthwith be readjusted to -9-

such Series A Conversion Price as would have obtained had the adjustment which was made upon the issuance of such Option or Convertible Security not exercised, converted or exchanged prior to such change been made upon the basis of such change; and (E) No readjustment pursuant to clause (B) or (D) above shall have the effect of increasing the Series A Conversion Price to an amount which exceeds the lower of (i) the Series A Conversion Price on the original adjustment date, or (ii) the Series A Conversion Price that would have resulted from any issuances of Additional Shares of Common Stock between the original adjustment date and such readjustment date. In the event the Corporation, after the Series A Original Issue Date, amends the terms of any such Options or Convertible Securities (whether such Options or Convertible Securities were outstanding on the Series A Original Issue Date or were issued after the Series A Original Issue Date), then such Options or Convertible Securities, as so amended, shall be deemed to have been issued after the Series A Original Issue Date and the provisions of this Subsection 4(d)(iii) shall apply. (iv) Adjustment of Series A Conversion Price Upon Issuance of Additional Shares of Common Stock. In the event the Corporation shall at any time after the Series A Original Issue Date issue Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to Section 4(d)(iii)), without consideration or for a consideration per share less than the applicable Series A Conversion Price in effect immediately prior to such issue, then and in such event, such Series A Conversion Price shall be reduced, concurrently with such issue, to a price (calculated to the nearest cent) determined by multiplying such Series A Conversion Price by a fraction, (A) the numerator of which shall be (1) the number of shares of Common Stock outstanding immediately prior to such issue plus (2) the number of shares of Common Stock which the aggregate consideration received or to be received by the Corporation for the total number of Additional Shares of Common Stock so issued would purchase at such Series A Conversion Price; and (B) the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of such Additional Shares of Common Stock so issued; provided that, (i) for the purpose of this Section 4(d)(iv), all shares of Common Stock issuable upon conversion or exchange of Convertible Securities outstanding immediately prior to such issue shall be deemed to be outstanding, and (ii) the number of shares of Common Stock deemed issuable upon conversion or exchange of such outstanding Convertible Securities shall not give effect to any adjustments to the conversion or exchange price or conversion or exchange rate of such Convertible Securities resulting from the issuance of Additional Shares of Common Stock that is the subject of this calculation. (v) Determination of Consideration. For purposes of this Subsection 4(d), the consideration received by the Corporation for the issue of any Additional Shares of Common Stock shall be computed as follows: -10-

(A) Cash and Property: Such consideration shall: (I) insofar as it consists of cash, be computed at the aggregate of cash received by the Corporation, excluding amounts paid or payable for accrued interest; (II) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board of Directors; and (III) in the event Additional Shares of Common Stock are issued together with other shares or securities or other assets of the Corporation for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses (I) and (II) above, as determined in good faith by the Board of Directors. (B) Options and Convertible Securities. The consideration per share received by the Corporation for Additional Shares of Common Stock deemed to have been issued pursuant to Section 4(d)(iii), relating to Options and Convertible Securities, shall be determined by dividing (x) the total amount, if any, received or receivable by the Corporation as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Corporation upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by (y) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities. (e) Adjustment for Stock Splits and Combinations. If the Corporation shall at any time or from time to time after the Series A Original Issue Date effect a subdivision of the outstanding Class A Common Stock, the Series A Conversion Price then in effect immediately before that subdivision shall be proportionately decreased. If the Corporation shall at any time or from time to time after the Series A Original Issue Date combine the outstanding shares of Class A Common Stock, the Series A Conversion Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this paragraph shall -11-

become effective at the close of business on the date the subdivision or combination becomes effective. (f) Adjustment for Certain Dividends and Distributions. In the event the Corporation at any time, or from time to time after the Series A Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Series A Conversion Price then in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Series A Conversion Price then in effect by a fraction: (1) the numerator of which shall be the total number of shares of Class A Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and (2) the denominator of which shall be the total number of shares of Class A Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Class A Common Stock issuable in payment of such dividend or distribution; provided, however, if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Series A Conversion Price shall be recomputed accordingly as of the close of business on such record date and thereafter the Series A Conversion Price shall be adjusted pursuant to this paragraph as of the time of actual payment of such dividends or distributions. (g) Adjustment for Merger or Reorganization, etc. Subject to the provisions of Section 2(c), if there shall occur any reorganization, recapitalization, consolidation or merger involving the Corporation in which the Class A Common Stock (but not the Series A Preferred Stock) is converted into or exchanged for securities, cash or other property (other than a transaction covered by paragraphs (e) or (f) of this Section 4), then, following any such reorganization, recapitalization, consolidation or merger, each share of Series A Preferred Stock shall be convertible into the kind and amount of securities, cash or other property which a holder of the number of shares of Class A Common Stock of the Corporation issuable upon conversion of one share of Series A Preferred Stock immediately prior to such reorganization, recapitalization, consolidation or merger would have been entitled to receive pursuant to such transaction; and, in such case, appropriate adjustment (as determined in good faith by the Board of Directors) shall be made in the application of the provisions in this Section 4 set forth with respect to the rights and interest thereafter of the holders of the Series A Preferred Stock, to the end that the provisions set forth in this Section 4 (including provisions with respect to changes in and other adjustments of the Series A Conversion Price) shall thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other property thereafter deliverable upon the conversion of the Series A Preferred Stock. -12-

(h) No Impairment. The Corporation will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section 4 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of the Series A Preferred Stock against impairment. (i) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Series A Conversion Price pursuant to this Section 4, the Corporation at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Series A Preferred Stock a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon the written request at any time of any holder of Series A Preferred Stock, furnish or cause to be furnished to such holder a certificate setting forth (i) the Series A Conversion Price then in effect, and (ii) the number of shares of Class A Common Stock and the amount, if any, of other securities, cash or property which then would be received upon the conversion of Series A Preferred Stock. (j) Notice of Record Date. In the event: (i) the Corporation shall take a record of the holders of its Class A Common Stock (or other stock or securities at the time issuable upon conversion of the Series A Preferred Stock) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any right to subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right; or (ii) of any capital reorganization of the Corporation, any reclassification of the Class A Common Stock of the Corporation, any consolidation or merger of the Corporation with or into another corporation (other than a consolidation or merger in which the Corporation is the surviving entity and its Class A Common Stock is not converted into or exchanged for any other securities or property), or any transfer of all or substantially all of the assets of the Corporation; or (iii) of the voluntary or involuntary dissolution, liquidation or winding-up of the Corporation, then, and in each such case, the Corporation will mail or cause to be mailed to the holders of the Series A Preferred Stock a notice specifying, as the case may be, (i) the record date for such dividend, distribution or right, and the amount and character of such dividend, distribution or right, or (ii) the effective date on which such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up is to take place, and the time, if any is to be fixed, as of which the holders of record of Class A Common Stock (or such other stock or securities at the time issuable upon the conversion of the Series A Preferred Stock) shall be entitled to exchange their shares of Common Stock (or such other stock or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, -13-

merger, transfer, dissolution, liquidation or winding-up. Such notice shall be mailed at least 10 days prior to the record date or effective date for the event specified in such notice. 5. Mandatory Conversion. (a) In the event that the Corporation elects to (and is eligible to) redeem less than all of the issued and outstanding shares of Series A Preferred Stock pursuant to Section 6(a), then, upon such redemption, the Corporation may, but is not obligated, to cause the remaining shares of Series A Preferred Stock which were not redeemed to be automatically converted into shares of Class A Common Stock at the then effective conversion ratio. On the date of a mandatory conversion pursuant to this Section 5 (a) ("Mandatory Conversion Date"), the number of authorized shares of Preferred Stock shall be automatically reduced by the number of shares of Preferred Stock that had been designated as Series A Preferred Stock, and all provisions included under the caption "Series A Convertible Preferred Stock", and all references to the Series A Preferred Stock, shall be deleted and shall be of no further force or effect. (b) All holders of record of shares of Series A Preferred Stock shall be given written notice of the Mandatory Conversion Date and the place designated for mandatory conversion of such shares of Series A Preferred Stock pursuant to this Section 5 and the redemption of the remaining shares of Series A Preferred Stock pursuant to Section 6 and Section 7. Such notice shall be sent by first class or registered mail, postage prepaid, mailed not less than 30 days nor more than 60 days prior to the Mandatory Redemption Date to each holder of record of the Series A Preferred Stock at such holder's address as the same appears on the stock register of the Corporation; provided that neither the failure to give such notice nor any defect therein shall affect the validity of the giving of notice for the mandatory conversion of any share of any share of Series A Preferred Stock to be converted except as to the holder to whom the Corporation has failed to give said notice or except as to the holder whose notice was defective. Upon receipt of such notice, each holder of shares of Series A Preferred Stock shall surrender his or its certificate or certificates for all such shares to the Corporation at the place designated in such notice, and shall thereafter receive certificates for the number of shares of Class A Common Stock to which such holder is entitled pursuant to this Section 5. On the Mandatory Conversion Date, the number of shares of the outstanding shares of Series A Preferred Stock not redeemed in accordance with Section 6(a) shall be deemed to have been converted into shares of Class A Common Stock and all rights set forth herein with respect to the Series A Preferred Stock so converted, including the rights, if any, to receive notices and vote (other than as a holder of Class A Common Stock) will terminate, except only the rights of the holders thereof, upon surrender of their certificate or certificates therefor, to receive certificates for the number of shares of Class A Common Stock into which such Series A Preferred Stock has been converted, and payment of any declared but unpaid dividends thereon. If so required by the Corporation, certificates surrendered for conversion shall be endorsed or accompanied by written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or by his or its attorney duly authorized in writing. As soon as practicable after the Mandatory Conversion Date and the surrender of the certificate or certificates for Series A Preferred Stock, the Corporation shall cause to be issued and delivered to such holder, or on his or its written order, a certificate or certificates for the number of full shares of Class A Common Stock issuable on such conversion in accordance with the provisions -14-

hereof and cash as provided in Section 4(b) in respect of any fraction of a share of Class A Common Stock otherwise issuable upon such conversion. (c) All certificates evidencing shares of Series A Preferred Stock which are required to be surrendered for conversion in accordance with the provisions hereof shall, from and after the Mandatory Conversion Date, be deemed to have been retired and cancelled and the shares of Series A Preferred Stock represented thereby converted into Class A Common Stock for all purposes, notwithstanding the failure of the holder or holders thereof to surrender such certificates on or prior to such date. Such converted Series A Preferred Stock may not be reissued, and the Corporation will thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of Series A Preferred Stock accordingly. 6. Redemption. (a) Subject to the right of the holders of Series A Preferred Stock to convert such shares in accordance with Section 4 hereof, beginning on the third anniversary of the Closing Date and continuing until the seventh anniversary of the Closing Date, the Corporation may redeem at its option all of the issued and outstanding shares of Series A Preferred Stock, at any time at a redemption price per share in cash (the "Optional Redemption Price") equal to the greater of (i) 90% of the Current Market Value of the number of shares of Class A Common Stock into which a share of Series A Preferred Stock could be converted by the holder on the date of the notice of redemption pursuant to Section 7(b) or (ii) an amount which will provide the holders of the Series A Preferred Stock with a 30% IRR on Original Investment to the date of redemption; provided that if the redemption occurs prior to the fourth anniversary of the Closing Date, the Optional Redemption Price shall not be less than the greater of (i) a 30% IRR on Original Investment and (ii) a Return on Investment of Three Times the Original Investment, in each case to the date of redemption; provided, further, that in the event the Optional Redemption Price is equal to 90% of the Current Market Value of the number of shares of Class A Common Stock into which a share of Series Preferred Stock could be converted on the date of the notice of redemption pursuant to Section 7(b), then the Corporation may redeem less than all (but in no event less than 50%) of the issued and outstanding shares of Series A Preferred Stock. (b) Promptly following the occurrence of a Change of Control, the Corporation shall notify (a "Change of Control Notice") the holders of the Series A Preferred Stock of such occurrence. Within thirty days after the Corporation sends a Change of Control Notice, each holder of shares of Series A Preferred Stock shall have the option to the extent the Corporation shall have funds legally available therefor, to require the Corporation to redeem such holder's shares of Series A Preferred Stock, or such portion thereof as may be determined by such holder, at a redemption price per share (the "Elective Redemption Price") in cash equal to the Liquidation Value as of the date of the Change of Control (which date shall be the redemption date for purposes hereof). Any election pursuant to this Section 6(b) must be made by written notice delivered to the offices of the Corporation, accompanied by certificates representing the shares to be redeemed within thirty days following the mailing of the Change of Control Notice. Such notice shall be signed by the holder of the shares to be redeemed and must specify the number of shares to be redeemed. -15-

(c) All outstanding shares of Series A Preferred Stock shall be redeemed by the Corporation at a price per share equal to the Liquidation Value plus all accrued but unpaid dividends that have not been added to the Accreted Value in accordance with Section 1(a) as of the date of redemption (the "Mandatory Redemption Price") on the seventh anniversary of the Closing Date (the "Mandatory Redemption Date"). If the Corporation does not have sufficient funds legally available to redeem the Series A Preferred Stock on the Mandatory Redemption Date, the Corporation shall redeem a pro rata portion of each holder's shares of Series A Preferred Stock out of funds legally available therefor and shall redeem the remaining shares to have been redeemed as soon as practicable after the Corporation has funds legally available therefor. (d) If the Corporation is unable or shall fail to discharge its obligation to redeem all outstanding shares of Series A Preferred Stock pursuant to Section 6(c) (a "Mandatory Redemption Obligation") for any reason, including as a result of the failure of the Corporation to have funds legally available to make such redemption, the Mandatory Redemption Obligation shall be discharged as soon as the Corporation is able to discharge such Mandatory Redemption Obligation and the Board of Directors shall take all action commercially reasonable to enable the Corporation to discharge such Mandatory Redemption Obligation, including without limitation increasing the capital surplus of the Corporation if possible. If and so long as any Mandatory Redemption Obligation with respect to the Series A Preferred Stock shall not be fully discharged, the Corporation shall not (i) declare or pay any dividend or distribution with respect to, or directly or indirectly, redeem, purchase, or otherwise acquire any Parity Stock or discharge any mandatory or optional redemption, sinking fund or other similar obligation in respect of any Parity Stock or Junior Stock (except in connection with a redemption, sinking fund or other similar obligation to be satisfied pro rata with the Series A Preferred Stock and except for dividends on Parity Stock which are payable solely in additional shares of or by the increase in the liquidation value of Parity Stock, in each case, pursuant to the terms thereof) or (ii) declare or pay any dividend or distribution with respect to, or directly or indirectly redeem, purchase, or otherwise acquire, any Junior Stock, or, directly or indirectly, discharge any mandatory or optional redemption, sinking fund or other similar obligation in respect of any Junior Stock (other than a redemption, purchase or other acquisition of shares of Common Stock made pursuant to an employee incentive or benefit plan or arrangement of the Corporation or any subsidiary or other agreement or arrangement between an employee and the Corporation or any subsidiary approved by the Board of Directors or any committee thereof and other than dividends on Junior Stock which are payable solely in additional shares of or by the increase in the liquidation value of Junior Stock, in each case, pursuant to the terms thereof). (e) Shares of Series A Preferred Stock which have been redeemed pursuant to this Section 6 will be cancelled and will not under any circumstances be reissued, sold or transferred and the Corporation will from time to time take such appropriate action as may be necessary to reduce the authorized Series A Preferred Stock accordingly. 7. Procedure for Redemption. (a) In the event that fewer than all the outstanding shares of Series A Preferred Stock are to be redeemed in accordance with the provisions of Section 6(a) (which in no event shall be less than 50% of the then outstanding Series A Preferred Stock), the number of -16-

shares to be redeemed shall be determined by the Board of Directors and the shares to be redeemed shall be selected pro rata (with any fractional shares being rounded to the nearest whole share). (b) In the event the Corporation shall redeem shares of Series A Preferred Stock pursuant to Section 6(a) or Section 6(c), notice of such redemption shall be given by first class or registered mail, postage prepaid, mailed not less than 30 days nor more than 60 days prior to the redemption date, to each holder of record of the shares to be redeemed at such holder's address as the same appears on the stock register of the Corporation; provided that neither the failure to give such notice nor any defect therein shall affect the validity of the giving of notice for the redemption of any share of Series A Preferred Stock to be redeemed except as to the holder to whom the Corporation has failed to give said notice or except as to the holder whose notice was defective. Each such notice shall state: (i) the redemption date; (ii) the number of shares of Series A Preferred Stock to be redeemed and, if fewer than all the shares held by such holder are to be redeemed in accordance with Section 6(a), the number of shares to be redeemed from such holder; (iii) the Optional Redemption Price or the Mandatory Redemption Price, as the case may be; and (iv) the place or places where certificates for such shares are to be surrendered for payment of the Optional Redemption Price or the Mandatory Redemption Price, as the case may be. (c) Notice having been received by the Corporation as set forth in Section 6(b) or having been mailed by the Corporation as set forth in Section 7(b), from and after the redemption date, dividends on the shares of Series A Preferred Stock so called pursuant to Section 6(a) or Section 6(c), or surrendered for redemption pursuant to Section 6(b), shall cease to accrue, and all rights of the holders thereof as stockholders of the Corporation (except the right to receive from the Corporation the Optional Redemption Price, the Mandatory Redemption Price or the Elective Redemption Price, as the case may be) shall cease. Upon surrender in accordance with said notice of the certificates for any shares so redeemed (properly endorsed or assigned for transfer, if the Board of Directors shall so require and the notice shall so state), such share shall be redeemed by the Corporation at the Optional Redemption Price, the Mandatory Redemption Price or the Elective Redemption Price, as the case may be. (d) Unless there shall have been a failure to pay the Optional Redemption Price, the Mandatory Redemption Price or the Elective Redemption Price, as applicable, on the applicable redemption date all rights of the holder of each share redeemed on such date as a stockholder of the Corporation by reason of the ownership of such share will cease, except the right to receive the Optional Redemption Price, the Mandatory Redemption Price or the Elective Redemption Price, as applicable, of such share, without interest, upon presentation and surrender of the certificate representing such share, and such share will not from and after such applicable redemption date be deemed to be outstanding. 8. Definitions. "A 30% IRR on Original Investment" shall mean in connection with the redemption of any share of Series A Preferred Stock, a 30% internal rate of return on investment to the holder of such share, calculated from the date of issuance of such share of Series A Preferred Stock to -17-

Such Purchaser is acquiring the Shares, and the shares of Common Stock into which the Shares may be converted, for his, her or its own account for investment and not with a view to, or for sale in connection with, any distribution thereof, nor with any present intention of distributing or selling the same; and, except as contemplated by this Agreement, such Purchaser has no present or contemplated agreement, undertaking, arrangement, obligation, indebtedness or commitment providing for the disposition thereof.

Such Purchaser agrees to the imprinting, so long as required by law, of a legend on certificates representing such Preferred Stock or any shares of Common Stock issued upon conversion of the Preferred Stock to the following effect: "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR IF AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY IS OBTAINED TO THE EFFECT THAT SUCH REGISTRATION IS NOT REQUIRED." The requirement to include the legend set forth above shall cease and terminate as to any particular shares of Preferred Stock or Common Stock (a) when, in the opinion of Ropes & Gray, or other counsel reasonably acceptable to the Company, such legend is no longer required in order to assure compliance by the Company with the Securities Act or (b) when such shares have been effectively registered under the Securities Act or transferred pursuant to Rule 144. Whenever (x) such requirement shall cease and terminate as to any such shares or (y) such shares shall be transferable under paragraph (k) of Rule 144, the holder thereof shall be entitled to receive from the Company, without expense, new certificates not bearing the legend set forth above.

The Purchasers intend that any increase in the Accreted Value (as defined in the Certificate of Designation) of the Preferred Stock will, when paid or accrued, be includible in the Purchasers' gross income for federal, state or local tax purposes. So long as the Company concludes in good faith, with the assistance and advice of its accountants and counsel, that there is a reasonable basis to make or file Tax Returns that are consistent with such intention, all the Tax Returns that the Company shall make or file shall be consistent with such intention. 7.8 Confidentiality. For one year after the Closing Date, each Purchaser will hold, and will use its reasonable efforts to cause its Permitted Transferees, and each Purchaser's and each Permitted Transferee's officers, partners, directors, employees, accountants, counsel, consultants, advisors and agents (the "Representatives") to hold, in confidence, at all times unless compelled to disclose by judicial or administrative process or by other Requirements of Law, all confidential documents and information concerning the Company and it Affiliates that are furnished to such Purchaser and its Permitted Transferees, except to the extent that such information can be shown to have been (i) previously known on a nonconfidential basis by such Purchaser, Permitted Transferee or such Representatives or (ii) in the public domain through no fault of such Purchaser, such Permitted Transferee or such Representative. If any Purchaser or Permitted Transferee, or any of their respective Representatives is requested to disclose any confidential information by judicial or administrative process or by other Requirements of Law, such Person shall promptly notify the Company of such request so that the Company may seek an appropriate protective order. Each Purchaser agrees that it will not, and will use its reasonable best efforts to cause its Permitted Transferees and the Representatives not to, use any confidential documents or information for any purpose other than monitoring and evaluating its investment in the Company and in connection with the transactions contemplated by this Agreement. If this Agreement is terminated, each Purchaser will, and will use its reasonable best efforts to cause its Representatives to, destroy or deliver to the Company all documents and other materials, and all copies thereof, obtained by such Purchaser, or on its behalf, from the Company in connection with this Agreement and an investment in the Company. 7.9 Schedule 13D and 13G.

7.10 Election of Directors. (a) The Company represents and warrants that there is one vacancy on the Board of Directors. Effective as of the Closing, the Board of Directors shall appoint one Purchaser Director designated by the holders of a majority of the Preferred Stock to fill the current vacancy and the Purchasers shall designate one person to serve as the Purchaser Observer. The Purchaser Director shall be appointed to each committee of the Board of Directors. The Purchaser Observer shall execute a confidentiality agreement with the Company in form and substance reasonably acceptable to the Company. (b) So long as the Purchasers and the Permitted Transferees hold at least 20% of the Underlying Common Stock, the holders of a majority of the Preferred Stock shall continue to have the right to nominate one person who shall be included among the Company's nominees for election to the Board as the Purchaser Director and, so long as they own at least 20% of the shares of Preferred Stock, the Purchasers shall have the right to designate one person to serve as Purchaser Observer. The Company shall nominate each person so designated as Purchaser Director and shall use reasonable efforts to have the nominee of the holders of a majority of the Preferred Stock elected to the Board of Directors. (c) If at any time holders of Preferred Stock entitled to nominate a director notify the Board of Directors of their wish to remove any incumbent Preferred Director as a director, that incumbent Preferred Director shall immediately resign from the Board or the Board shall vote to remove the Purchaser Director (if his or her removal is permitted under the Bylaws and the DGCL). Removal of an incumbent Preferred Director by the Board or the resignation of an incumbent Purchaser Director otherwise than at the request of the holders of a majority of the Preferred Stock require their prior written consent unless the removal is based upon the Purchaser Director's willful misconduct or gross negligence. (d) If at any time a vacancy is created on the Board by reason of the incapacity, death, removal or resignation of an incumbent Purchaser Director, the holders of a majority of the Preferred Stock may designate a person to fill the vacancy (who promptly shall be appointed by the incumbent directors). If at any time an incumbent Purchaser Observer is unable to serve in that capacity by reason of his or her incapacity, death or resignation, the Purchasers may designate a person to fill the vacancy or may leave the position unfilled. (e) At each meeting of stockholders of the Company at which directors are elected, the nominees for directors proposed by the Company shall include the Preferred Director required pursuant to this Agreement. 7.11 Standstill.

Company, except (x) shares of Common Stock that may be issuable upon the conversion of the Preferred Stock, (y) securities of the Company or any of its successors issued as dividends or as a result of stock splits and similar reclassifications or received in a consolidation, merger or other business combination in respect of, in exchange for or upon conversion of Preferred Stock or securities held by the Purchasers or any of their Affiliates at the time of such dividend, split, reclassification, consolidation or merger or business combination or (z) shares of Common Stock of the Company acquired in market or privately negotiated transactions provided that the aggregate number of such shares of Common Stock so acquired plus all shares of Underlying Common Stock held by such Purchasers or their Affiliates do not exceed at the time of such acquisition in excess of twenty-five (25%) of all the issued and outstanding shares of Common Stock of the Company on a fully-diluted basis, assuming the exercise of all securities exercisable into Common Stock and the conversion of all securities convertible into Common Stock. 7.12 Transfer Restrictions. No Purchaser or Permitted Transferee shall assign, pledge, sell or otherwise transfer any Preferred Stock, except (i) to an Affiliate of a Purchaser, (ii) to any other Person with the prior written consent of the Company's Board of Directors, (iii) to the Company in connection with its redemption or conversion to Common Stock pursuant to the Certificate of Designation, or (iv) in connection with a tender offer approved by the Company's Board of Directors.

The Company shall use the proceeds from the sale of the Preferred Stock (i) to fund acquisitions, (ii) subject to the limitations in the Certificate of Designation, to repurchase outstanding shares of Common Stock, (iii) to repay Indebtedness of the Company and/or (iv) for general corporate purposes. 7.14 Listing of Shares. The Company shall take all actions necessary to have listed with the Nasdaq Stock Market all shares of Common Stock which become issuable upon conversion of the Preferred Stock. ARTICLE VIII INDEMNIFICATION; TERMINATION 8.1 Indemnification. Effective upon the Closing, the Company agrees to indemnify and hold harmless the Purchasers and their Affiliates and their officers, directors, agents, employees, subsidiaries, partners and controlling Persons (each, a "Company Indemnified Party") to the fullest extent permitted by law, from and against any and all losses, demands, actions, costs, claims, damages, expenses (including reasonable fees, disbursements and other charges of counsel) or other liabilities (collectively, "Company Liabilities") incurred or suffered by such Company Indemnified Party resulting from or arising out of (i) any misrepresentation or breach of any representation or warranty of the Company in this Agreement, any other Transaction Document or any certificate or instrument delivered pursuant thereto or (ii) any breach of any covenant or obligation of the Company in this Agreement or any other Transaction Document; provided that the Company shall be liable under this Section 8.1 in respect of 25

Company Liabilities only to the extent to which the aggregate of such Company Liabilities incurred by such Company Indemnified Parties exceeds $250,000, in which case the Company shall be liable under this Section 8.1 for the amount of such Company Liabilities in excess of $250,000. 8.2 Notification. The Company Indemnified Party, under Section 8.1(iii) will, promptly after the receipt of notice of the commencement of any action, investigation, claim or other proceeding against such Company Indemnified Party in respect of which indemnity may be sought from the Company under Section 8.1(iii), notify the Company in writing of the commencement thereof stating a brief summary of the facts known to the Company Indemnified Party giving rise to such indemnity rights. The omission of any Company Indemnified Party so to notify the Company of any such action shall not relieve the Company from any liability which it may have to such Company Indemnified Party under Section 8.1(iii) unless, and only to the extent that, such omission results in prejudice to the Company. In case any such action, claim or other proceeding shall be brought against any Company Indemnified Party and it shall notify the Company of the commencement thereof, the Company shall be entitled to assume the defense thereof at its own expense, with counsel satisfactory to the Company Indemnified Party; provided, that any Company Indemnified Party may, at its own expense, retain separate counsel to participate in such defense. Notwithstanding the foregoing, in any action, claim or proceeding in which both the Company, on the one hand, and a Company Indemnified Party, on the other hand, is, or is reasonably likely to become, a party, such Company Indemnified Party shall have the right to employ separate counsel at the Company's expense and to control its own defense of such action, claim or proceeding if, (a) the Company has failed to assume the defense and employ counsel as provided herein, (b) the Company has agreed in writing to pay such fees and expenses of separate counsel or (c) in the reasonable opinion of counsel to such Company Indemnified Party, a conflict or likely conflict exists between the Company, on the one hand, and such Company Indemnified Party, on the other hand, that would make such separate representation advisable, provided, however, that the Company shall not in any event be required to pay the fees and expenses of more than one separate counsel (and if deemed necessary by such separate counsel, appropriate local counsel who shall report to such separate counsel). The Company agrees that it will not, without the prior written consent of a Company Indemnified Party, settle, compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated hereby (if such Company Indemnified Party is a party thereto or has been actually threatened to be made a party thereto) unless such settlement, compromise or consent includes an unconditional release of such Company Indemnified Party from all liability arising or that may arise out of such claim, action or proceeding. The Company shall not be liable for any settlement of any claim, action or proceeding effected against a Company Indemnified Party without the prior written consent of the Company. 26

"Stockholders" means the Purchasers and any persons or entities to whom the rights granted under this Agreement are transferred by any Purchasers, their successors or assigns pursuant to Section 3 hereof. 2. Registration Rights 2.1 Required Registrations. (a) A Stockholder or Stockholders holding in the aggregate at least 20% of the Registrable Shares then outstanding may request, in writing, that the Company effect the registration of Registrable Shares owned by the Stockholder or Stockholders having an aggregate value of at least $5,000,000 (based on the then current public market price). (b) Upon receipt of any request for registration pursuant to this Section 2, the Company shall promptly give written notice of such proposed registration to all other Stockholders. Such Stockholders shall have the right, by giving written notice to the -2-

Company within 30 days after the Company provides its notice, to elect to have included in such registration such of their Registrable Shares as such Stockholders may request in such notice of election, subject in the case of an underwritten offering to the approval of the managing underwriter as provided in Section 2.1(c) below. Thereupon, the Company shall, as expeditiously as possible, use its best efforts to effect the registration on Form S-1 or, if available, S-3 (or in each case any successor form) of all Registrable Shares which the Company has been requested to so register. (c) If the Initiating Holders intend to distribute the Registrable Shares covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Section 2.1(a) and the Company shall include such information in its written notice referred to in Section 2.1(b). The right of any other Stockholder to include its Registrable Shares in such registration pursuant to Section 2.1(a) shall be conditioned upon such other Stockholder's participation in such underwriting on the terms set forth herein. If the Company desires that any officers or directors of the Company holding securities of the Company be included in any registration for an underwritten offering requested pursuant to this Section 2.1(c) or if other holders of securities of the Company who are entitled, by contract with the Company, to have securities included in such a registration (the "Other Holders") request such inclusion, the Company may include the securities of such officers, directors and Other Holders in such registration and underwriting on the terms set forth herein. The Company shall (together with all Stockholders, officers, directors and Other Holders proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form (including, without limitation, customary indemnification and contribution provisions on the part of the Company) with the managing underwriter; provided that such underwriting agreement shall not provide for indemnification or contribution obligations on the part of Stockholders materially greater than the obligations of the Stockholders pursuant to Section 2.5. Notwithstanding any other provision of this Section 2.1(c), if the managing underwriter advises the Company that the inclusion of all shares requested to be registered would adversely affect the offering (including without limitation the price at which such shares will be offered to the public), the securities of the Company held by officers or directors of the Company (other than Registrable Shares) and the securities held by Other Holders (other than Registrable Shares) shall be excluded from such registration and underwriting to the extent deemed advisable by the managing underwriter, and if a further limitation of the number of shares is required, the number of shares that may be included in such registration and underwriting shall be allocated among all holders of Registrable Shares requesting registration in proportion, as nearly as practicable, to the respective number of Common Stock (on an as-converted basis) which they held at the time the Company gives the notice specified in Section 2.2(b). If any holder of Registrable Shares, officer, director or Other Holder who has requested inclusion in such registration as provided above disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company, and the securities so withdrawn shall also be withdrawn from registration. If the managing underwriter has not limited the number of Registrable Shares or other securities to be underwritten, the Company may include securities for its own account in such registration if the managing underwriter so agrees and if the number of Registrable Shares and other securities which would otherwise have been included in such registration and underwriting will not thereby be limited. -3-

(d) The Company shall have the right to select the managing underwriter(s) for any underwritten offering requested pursuant to Section 2.1(a), subject to the approval of the Initiating Holders, which approval will not be unreasonably withheld. (e) The Company shall not be required to effect more than three registrations pursuant to Section 2.1(a). For purposes of this Section 2.1(e), a Registration Statement shall not be counted until such time as such Registration Statement has been declared effective by the Commission (unless the Initiating Holders withdraw their request for such registration (other than as a result of information concerning the business or financial condition of the Company which is made known to the Stockholders after the date on which such registration was requested) and elect not to pay the Registration Expenses therefor pursuant to Section 2.4). Notwithstanding the foregoing, (i) on one occasion in the event that the holders of Registrable Securities have not sold at least 75% of the shares registered pursuant to such registration they may elect, within 30 days of the termination thereof, by written notice to the Company to pay the Registration Expenses relating to the registration in which case such Registration Statement shall not be counted pursuant to this Section 2.1(e), (ii) in the event that the Company withdraws a Registration Statement after it has become effective or such Registration Statement otherwise ceases to be effective for the period described in Section 2.3(a)(ii) (which 180 days need not be contiguous ) and the holders of Registrable Securities have not sold at least 75% of the shares registered pursuant to such registration, such Registration Statement shall not be counted pursuant to this Section 2.1(e) and (iii) on one occasion, in the event that the managing underwriter advises the Company pursuant to Section 2.1(c) that the number of shares that is advisable to be sold in such registration is less than 75% of the shares requested to be sold by the Stockholders, then the Initiating Holders, acting by majority, may, within two business days of such determination by the managing underwriter, elect to withdraw their request pursuant to this Section 2.1 and not have the registration counted as a registration pursuant to this Section 2.1(e). (f) If at the time of any request to register Registrable Shares by Initiating Holders pursuant to this Section 2.1, the Company is engaged or has plans to engage in a registered public offering or is engaged in any other activity which, in the good faith determination of the Company's Board of Directors, would be adversely affected by the requested registration, then the Company may at its option direct that such request be delayed for a period not in excess of 90 days from the date of such request, such right to delay a request to be exercised by the Company not more than twice in any 12-month period. 2.2 Incidental Registration. (a) Whenever the Company proposes to request the effectiveness of a Registration Statement (other than a Registration Statement filed pursuant to Section 2.1) at any time and from time to time, it will, prior to such effectiveness, give written notice to all Stockholders of its intention to do so; provided, that (i) no such notice need be given if no Registrable Shares are to be included therein as a result of a determination of the managing underwriter pursuant to Section 2.2(b) and (ii) no such notice need be given to any Stockholder with respect to Registrable Shares that (A) can be sold pursuant to Rule 144(k) under the Securities Act and (B) no longer bear a restrictive legend on the certificate evidencing such Shares (however, in the case of clause (ii) the Company shall provide notice to the Purchasers). -4-

Upon the written request of a Stockholder or Stockholders given within 20 days after the Company provides such notice (which request shall state the intended method of disposition of such Registrable Shares), the Company shall use its best efforts to cause all Registrable Shares which the Company has been requested by such Stockholder or Stockholders to register to be registered under the Securities Act to the extent necessary to permit their sale or other disposition in accordance with the intended methods of distribution specified in the request of such Stockholder or Stockholders; provided that the Company shall have the right to postpone or withdraw any registration effected pursuant to this Section 2.2 without obligation to any Stockholder. (b) If the registration for which the Company gives notice pursuant to Section 2.2(a) is a registered public offering involving an underwriting, the Company shall so advise the Stockholders as a part of the written notice given pursuant to Section 2.2(a). In such event, the right of any Stockholder to include its Registrable Shares in such registration pursuant to Section 2.2 shall be conditioned upon such Stockholder's participation in such underwriting on the terms set forth herein. All Stockholders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for the underwriting by the Company, Notwithstanding any other provision of this Section 2.2, if the managing underwriter determines that the inclusion of all shares requested to be registered would adversely affect the offering, the Company may limit the number of Registrable Shares to be included in the registration and underwriting. The Company shall so advise all holders of Registrable Shares requesting registration, and the number of shares that are entitled to be included in the registration and underwriting shall be allocated in the following manner. The securities of the Company held by holders other than Stockholders and Other Holders shall be excluded from such registration and underwriting to the extent deemed advisable by the managing underwriter, and, if a further limitation on the number of shares is required, the number of shares that may be included in such registration and underwriting shall be allocated among all Stockholders and Other Holders requesting registration in proportion, as nearly as practicable, to the respective number of shares of Common Stock (on an as-converted basis) which they held at the time the Company gives the notice specified in Section 2.2(a) except to the extent that the Company is obligated under any contractual provision existing on the date hereof to allocate such shares first to Other Holders. If any Stockholder or Other Holder would thus be entitled to include more securities than such holder requested to be registered, the excess shall be allocated among other requesting Stockholders and Other Holders pro rata in the manner described in the preceding sentence. If any holder of Registrable Shares or any officer, director or Other Holder disapproves of the terms of any such underwriting, such person may elect to withdraw therefrom by written notice to the Company, and any Registrable Shares or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration. (c) Notwithstanding the foregoing, the Company shall not be required, pursuant to this Section 2.2, to include any Registrable Shares in a Registration Statement if such Registrable Shares can then be sold pursuant to Rule 144(k) under the Securities Act. 2.3 Registration Procedures. -5-

(a) If and whenever the Company is required by the provisions of this Agreement to use its best efforts to effect the registration of any Registrable Shares under the Securities Act, the Company shall: (i) file with the Commission a Registration Statement with respect to such Registrable Shares for an offering to be made on a continuous or delayed basis (a so-called "shelf registration statement") and use its best efforts to cause that Registration Statement to become effective as soon as possible; (ii) as expeditiously as possible prepare and file with the Commission any amendments and supplements to the Registration Statement and the prospectus included in the Registration Statement as may be necessary to comply with the provisions of the Securities Act (including the anti-fraud provisions thereof) and to keep the Registration Statement effective for 180 days from the effective date or such lesser period until all such Registrable Shares are sold; (iii) as expeditiously as possible furnish to each Selling Stockholder such reasonable numbers of copies of the Prospectus, including any preliminary Prospectus, in conformity with the requirements of the Securities Act, and such other documents as such Selling Stockholder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Shares owned by such Selling Stockholder; (iv) as expeditiously as possible use its best efforts to register or qualify the Registrable Shares covered by the Registration Statement under the securities or Blue Sky laws of such states as the Selling Stockholders shall reasonably request, and do any and all other acts and things that may be necessary or desirable to enable the Selling Stockholders to consummate the public sale or other disposition in such states of the Registrable Shares owned by the Selling Stockholder; provided, however, that the Company shall not be required in connection with this paragraph (iv) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction; (v) as expeditiously as possible, cause all such Registrable Shares to be listed on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed; (vi) promptly provide a transfer agent and registrar for all such Registrable Shares not later than the effective date of such registration statement; (vii) promptly make available for inspection by the Selling Stockholders, any managing underwriter participating in any disposition pursuant to such Registration Statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the Selling Stockholders, all financial and other records, pertinent corporate documents and properties of the Company and cause the Company's officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such Registration Statement; -6-

(viii) as expeditiously as possible, notify each Selling Stockholder, promptly after it shall receive notice thereof, of the time when such Registration Statement has become effective or a supplement to any Prospectus forming a part of such Registration Statement has been filed; (ix) as expeditiously as possible following the effectiveness of such Registration Statement, notify each seller of such Registrable Shares of any request by the Commission for the amending or supplementing of such Registration Statement or Prospectus; and (x) use its reasonable efforts to cooperate with the seller in the disposition of the Common Stock covered by such registration statement, including without limitation in the case of an underwritten offering causing key executives of the Company and its subsidiaries to participate on a reasonable basis under the direction of the managing underwriter in a "road show" scheduled by such managing underwriter in such locations and of such duration as in the reasonable judgment of such managing underwriter are appropriate for such underwritten offering. (b) If the Company has delivered a Prospectus to the Selling Stockholders and after having done so the Prospectus is amended to comply with the requirements of the Securities Act, the Company shall promptly notify the Selling Stockholders and, if requested, the Selling Stockholders shall immediately cease making offers of Registrable Shares and return all Prospectuses to the Company. The Company shall promptly provide the Selling Stockholders with revised Prospectuses and, following receipt of the revised Prospectuses, the Selling Stockholders shall be free to resume making offers of the Registrable Shares. (c) In the event that, in the judgment of the Company, it is advisable to suspend use of a Prospectus included in a Registration Statement due to pending material developments or other events that have not yet been publicly disclosed and as to which the Company believes public disclosure would be detrimental to the Company, the Company shall notify all Selling Stockholders to such effect, and, upon receipt of such notice, each such Selling Stockholder shall immediately discontinue any sales of Registrable Shares pursuant to such Registration Statement until such Selling Stockholder has received copies of a supplemented or amended Prospectus or until such Selling Stockholder is advised in writing by the Company that the then current Prospectus may be used and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus. Notwithstanding anything to the contrary herein, the Company shall not exercise its rights under this Section 2.3(c) to suspend sales of Registrable Shares for a period in excess of 90 days in any 365-day period. 2.4 Allocation of Expenses. The Company will pay all Registration Expenses for all registrations under this Agreement; provided, however, that if a registration under Section 2.1 is withdrawn at the request of the Initiating Holders (other than as a result of information concerning the business or financial condition of the Company which is made known to the Stockholders after the date on which such registration was requested) and if the Initiating Holders elect not to have such registration counted as a registration requested under -7-

Section 2.1, the requesting Stockholders shall pay the Registration Expenses of such registration pro rata in accordance with the number of their Registrable Shares included in such registration. For purposes of this Section, the term "Registration Expenses" shall mean all expenses incurred by the Company in complying with this Agreement, including, without limitation, all registration and filing fees, exchange listing fees, printing expenses, fees and expenses of counsel for the Company and the fees and expenses of one counsel selected by the Selling Stockholders to represent the Selling Stockholders, state Blue Sky fees and expenses, and the expense of any special audits incident to or required by any such registration, but excluding underwriting discounts, selling commissions and the fees and expenses of Selling Stockholders' own counsel (other than the counsel selected to represent all Selling Stockholders). 2.5 Indemnification and Contribution. (a) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, the Company will indemnify and hold harmless each Selling Stockholder, each underwriter of such Registrable Shares, and each officer, director, manager, partner, employee of such person and each other person, if any, who controls such Selling Stockholder or underwriter within the meaning of the Securities Act or the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which such Selling Stockholder, underwriter or controlling person may become subject under the Securities Act, the Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, (ii) the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any violation by the Company or its subsidiaries of any federal or state securities law applicable to the Company or any of its subsidiaries relating to any action or inaction by the Company or any of its subsidiaries in connection with the registration effected by such Registration Statement; and the Company will reimburse such Selling Stockholder, underwriter and each such controlling person for any legal or any other expenses reasonably incurred by such Selling Stockholder, underwriter or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case only to the extent that any such loss, claim, damage or liability arises out of or is based upon (x) any untrue statement or omission made in such Registration Statement, preliminary prospectus or prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by or on behalf of such Selling Stockholder, underwriter or controlling person specifically for use in the preparation thereof or (y) any action or inaction of any Stockholder or Indemnified Party (as defined below) in contradiction of the Company's instructions or directions or any failure to follow any instructions or directions of the Company, including without limitation those with respect to prospectus delivery requirements or requirements to cease making offers of Registrable Shares pursuant to Section 2.3(b) or Section 2.3(c). (b) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, each Selling Stockholder, severally and not -8-

jointly, will indemnify and hold harmless the Company, each of its directors and officers and each underwriter (if any) and each person, if any, who controls the Company or any such underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which the Company, such directors and officers, underwriter or controlling person may become subject under the Securities Act, Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, if the statement or omission was made in reliance upon and in conformity with information relating to such Selling Stockholder furnished in writing to the Company by or on behalf of such Selling Stockholder specifically for use in connection with the preparation of such Registration Statement, prospectus, amendment or supplement; provided, however, that the obligations of a Selling Stockholder hereunder shall be limited to an amount equal to the proceeds to such Selling Stockholder of Registrable Shares sold in connection with such registration. (c) Each party entitled to indemnification under this Section (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld); and, provided, further, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section except to the extent that the Indemnifying Party is adversely affected by such failure. The Indemnified Party may participate in such defense at such party's expense; provided, however, that the Indemnifying Party shall pay such expense if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between the Indemnified Party and any other party represented by such counsel in such proceeding; provided further that in no event shall the Indemnifying Party be required to pay the expenses of more than one law firm per jurisdiction as counsel for the Indemnified Party. The Indemnifying Party also shall be responsible for the expenses of such defense if the Indemnifying Party does not elect to assume such defense. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation, and no Indemnified Party shall consent to entry of any judgment or settle such claim or litigation without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld. (d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this Section 2.5 is due in accordance -9-

with its terms but for any reason is held to be unavailable to an Indemnified Party in respect to any losses, claims, damages and liabilities referred to herein, then the Indemnifying Party shall, in lieu of indemnifying such Indemnified Party, contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities to which such party may be subject in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Selling Stockholders on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company and the Selling Stockholders shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of material fact related to information supplied by the Company or the Selling Stockholders and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Selling Stockholders agree that it would not be just and equitable if contribution pursuant to this Section 2.5 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph of Section 2.5, (a) in no case shall any one Selling Stockholder be liable or responsible for any amount in excess of the net proceeds received by such Selling Stockholder from the offering of Registrable Shares and (b) the Company shall be liable and responsible for any amount in excess of such proceeds; provided, however, that no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section, notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought shall not relieve such party from any other obligation it or they may have thereunder or otherwise under this Section. No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without its prior written consent, which consent shall not be unreasonably withheld. 2.6 Other Matters with Respect to Underwritten Offerings. In the event that Registrable Shares are sold pursuant to a Registration Statement in an underwritten offering pursuant to Section 2.1, the Company agrees to (a) enter into an underwriting agreement containing customary representations and warranties with respect to the business and operations of the Company and customary covenants and agreements to be performed by the Company, including without limitation customary provisions with respect to indemnification by the Company of the underwriters of such offering; (b) use its best efforts to cause its legal counsel to render customary opinions to the underwriters with respect to the Registration Statement; and (c) use its best efforts to cause its independent public accounting firm to issue customary "cold comfort letters" and auditors' consent to the underwriters with respect to the Registration Statement and provide each seller of Registrable Securities a signed counterpart of such legal opinion, addressed or confirmed to such seller. 2.7 Information by Holder. Each holder of Registrable Shares included in any registration shall furnish to the Company such information regarding such holder and the distribution proposed by such holder as the Company may reasonably request in writing and as -10-

shall be required in connection with any registration, qualification or compliance referred to in this Agreement. (a) "Stand-Off" Agreement; Confidentiality of Notices. Each Stockholder, if requested by the Company and the managing underwriter of an underwritten public offering by the Company of Common Stock, shall not sell or otherwise transfer or dispose of any Registrable Shares or other securities of the Company held by such Stockholder for a period of 90 days following the effective date of a Registration Statement; provided, that all officers and directors of the Company enter into similar agreements. The Company may impose stop-transfer instructions with respect to the Registrable Shares or other securities subject to the foregoing restriction until the end of such 90-day period. Any Stockholder receiving any written notice from the Company regarding the Company's plans to file a Registration Statement shall treat such notice confidentially and shall not disclose such information to any person other than as necessary to exercise its rights under this Agreement. 2.8 Existing Registration Rights. As of the date hereof, except with regard to certain registration rights granted pursuant to a certain 1995 Registration Rights Agreement dated as of December 22, 1995, there are no existing rights with respect to registration or sale or resale under the Securities Act or the securities or blue sky laws of any state or jurisdiction of any securities of the Company. 2.9 Limitations on Subsequent Registration Rights. The Company shall not, without the prior written consent of Stockholders holding at least 50% of the Registrable Shares then held by all Stockholders, enter into any agreement (other than this Agreement) with any holder or prospective holder of any securities of the Company which grants such holder or prospective holder rights to include securities of the Company in any Registration Statement, unless such rights to include securities in a registration initiated by the Company or by Stockholders are not more favorable than the rights granted to Other Holders under Sections 2.1 and 2.2 of this Agreement. 2.10 Rule 144 Requirements. The Company agrees to: (a) make and keep current public information about the Company available, as those terms are understood and defined in Rule 144; (b) use its best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and (c) furnish to any holder of Registrable Shares upon request (i) a written statement by the Company as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), (ii) a copy of the most recent annual or quarterly report of the Company, and (iii) such other reports and documents of the Company as such holder may -11-

reasonably request to avail itself of any similar rule or regulation of the Commission allowing it to sell any such securities without registration. 2.11 Termination. All of the Company's obligations to register Registrable Shares under Sections 2.1 and 2.2 of this Agreement shall terminate on the earlier of (a) fifteenth anniversary of the date of this Agreement, (b) the date on which all of the Registrable Shares have been sold by the Stockholders, or (c) the date on which all the Registrable Shares (in the opinion of the Stockholders' counsel) may be immediately sold by the Stockholders without registration and without restriction (including without limitation as to volume by each holder thereof) as to the number of Registrable Shares to be sold, pursuant to Rule 144(k) or otherwise. 3. Transfers of Rights. This Agreement, and the rights and obligations of each Purchaser hereunder, may be assigned by such Purchaser to any person to whom the Shares may be transferred under the Certificate of Designations relating to the Shares, and such transferee shall be deemed a "Purchaser" for purposes of this Agreement; provided that the transferee provides written notice of such assignment to the Company and agrees in writing to be bound hereby. 4. General. (a) Severability. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement. (b) Specific Performance. In addition to any and all other remedies that may be available at law in the event of any breach of this Agreement, each Purchaser shall be entitled to specific performance of the agreements and obligations of the Company hereunder and to such other injunctive or other equitable relief as may be granted by a court of competent jurisdiction. (c) Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware (without reference to the conflicts of law provisions thereof). (d) Notices. All notices, requests, consents, and other communications under this Agreement shall be in writing and shall be deemed delivered (i) two business days after being sent by registered or certified mail, return receipt requested, postage prepaid or (ii) one business day after being sent via a reputable nationwide overnight courier service guaranteeing next business day delivery, in each case to the intended recipient as set forth below: If to the Company, at 25 Greens Hill Lane, P.O.

Any party may give any notice, request, consent or other communication under this Agreement using any other means (including, without limitation, personal delivery, messenger service, telecopy, first class mail or electronic mail), but no such notice, request, consent or other communication shall be deemed to have been duly given unless and until it is actually received by the party for whom it is intended. Any party may change the address to which notices, requests, consents or other communications hereunder are to be delivered by giving the other parties notice in the manner set forth in this Section. (e) Complete Agreement. This Agreement constitutes the entire agreement and understanding of the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings relating to such subject matter. (f) Amendments and Waivers. Any term of this Agreement may be amended or terminated and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), with the written consent of the Company and the holders of at least 50% of the Registrable Shares held by all of the Stockholders; provided, that this Agreement may be amended with the consent of the holders of less than all Registrable Shares only in a manner which applies to all such holders in the same fashion. Any such amendment, termination or waiver effected in accordance with this Section 4(f) shall be binding on all parties hereto, even if they do not execute such consent. No waivers of or exceptions to any term, condition or provision of this Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision. (g) Future Changes in Registration Requirements. In the event that the registration requirements under the Securities Act are amended or eliminated to accommodate a "Company registration" or similar approach, this Agreement shall be deemed amended to the extent necessary to reflect such changes and the intent of the parties hereto with respect to the benefits and obligations of the parties, and in such connection, the Company shall use reasonable efforts to provide holders of Registrable Securities equivalent benefits to those provided under this Agreement.

This Agreement may be executed by facsimile signatures. (j) Section Headings. The section headings are for the convenience of the parties and in no way alter, modify, amend, limit or restrict the contractual obligations of the parties. -13-

DEFINITIONS. Capitalized terms used herein without definition shall have the meanings assigned to such terms in the Credit Agreement. 2. AMENDMENTS TO SECTION 4A.6.1 OF THE CREDIT AGREEMENT. As of the First Amendment Effective Date (as hereinafter defined), Section 4A.6.1 of the Credit Agreement is hereby amended by deleting the subsections (a) and (b) in their entirety and restating them as follows:

-2- "(a) To the extent that all or any portion of the Term Loan bears interest during such Interest Period at the Base Rate, the Term Loan or such portion thereof shall bear interest during such Interest Period at the rate of 2.000% per annum (the "Term Loan Base Rate Margin") above the Base Rate. (b) At the option of the Domestic Borrowers, and upon notice given to the Administrative Agent pursuant to Section 4A.6.2, so long as no Default or Event of Default has occurred or is continuing, to the extent that all or any portion of the Term Loan bears interest during such Interest Period at the Eurodollar Rate, the Term Loan or such portion shall bear interest during such Interest Period at the rate of 3.500% per annum (the "Term Loan Eurodollar Margin") above the Eurodollar Rate." 3.

AMENDMENTS TO SECTION 19 OF THE CREDIT AGREEMENT. As of the First Amendment Effective Date (as hereinafter defined), Section 19 of the Credit Agreement is hereby amended by deleting Section 19 in its entirety and restating it as follows: "Section 19. SYNDICATION AND PARTICIPATION. It is understood and agreed that each Bank shall have the right to assign at any time all or any portion of its Commitment (and interests in the risk relating to any Revolving Credit Loans, outstanding Letters of Credit, and Bankers' Acceptances) or its Term Loan Percentage of the Term Loan, in an amount equal to or greater than $2,500,000 (or, if less, in a minimum amount equal to all of such Bank's Commitment (and interests in the risk relating to any Revolving Credit Loans, outstanding Letters of Credit, and Bankers' Acceptances) or its Term Loan Percentage of the Term Loan), to additional banks, other financial institutions or other entities whose business is to purchase and sell loan assets in the normal course acceptable to the Administrative Agent or the Canadian Agent and, so long as no Event of Default has occurred and is continuing, the Parent (unless an assignment is to a Bank or to an affiliate of a Bank (so long as such assignment would not result in increased costs to the Borrowers hereunder), in which case acceptance by such Bank Agent and the Parent shall not be necessary and no minimum assignment amount shall apply), which acceptance shall not be unreasonably withheld, PROVIDED that a Bank may assign all or a portion of its Canadian Commitment Percentage and Canadian Loans outstanding, Canadian Letters of Credit and Bankers' Acceptances, only to an Eligible Canadian Assignee, and that each bank or other financial institution which executes and delivers to the

-3- applicable Bank Agent and the Borrowers hereunder an Assignment and Acceptance in the form attached hereto as Exhibit H. Upon the execution and delivery of such Assignment and Acceptance, (a) the Borrowers shall issue to the bank or other financial institution applicable Notes in the amount of such bank's or other financial institution's Domestic Commitment, portion of the Term Loan or Canadian Commitment, as applicable, dated the Effective Date or such other date as may be specified by the appropriate Bank Agent and otherwise completed in substantially the form of the Notes executed and delivered on the Effective Date; and (b) the assignee bank or financial institution shall pay a processing and recordation fee of $3,500 to the Administrative Agent. Each Bank shall also have the right to grant participations to one or more banks, other financial institutions or other entities whose business is to purchase and sell loan assets in the normal course in or to all or any part of any Loans owing to such Bank and the Note held by such Bank PROVIDED that (i) any such sale or participation shall not affect the rights and duties of the selling Bank hereunder to the Borrowers and (ii) the only rights granted to the participant pursuant to such participation arrangements with respect to waivers, amendments or modifications of the Loan Documents shall be the rights to approve waivers, amendments or modifications that would require consent by ALL Banks under Section 15.8, and any participant shall be entitled to the benefits of Sections 5.5, 5.6, 5.9, 5.14 and 17 as if it were a Bank hereunder, provided, however that no Borrower shall be required to pay any amount which is greater than such amount that otherwise would have been payable to the Bank which sold such participation. Notwithstanding the foregoing, no syndication or assignment shall operate to increase the Total Commitment or amount of the Term Loan hereunder or reduce the Domestic Commitment or portion of the Term Loan of any Bank to an amount less than $2,500,000 (or, if less, in a minimum amount equal to all of such Bank's Commitment (and interests in the risk relating to any Revolving Credit Loans, outstanding Letters of Credit, and Bankers' Acceptances) or its Term Loan Percentage of the Term Loan), or otherwise alter the substantive terms of this Agreement.
