In this regard, and without limiting the generality of the foregoing, in the case of any consolidation or merger of the Corporation with or into any other entity (other than a merger which does not result in any reclassification, conversion, exchange or cancellation of the Common Stock), or in case of any sale or transfer of all or substantially all the assets of the Corporation, or the reclassification of the Common Stock into any other form of capital stock of the Corporation, whether in whole or in part, each share of Nonvoting Common Stock shall, after such consolidation, merger, sale, or transfer or reclassification, be converted into the kind and amount of shares of stock and other securities and property which such holder would have been entitled to receive upon such consolidation, merger, sale, or transfer or reclassification if such holder had held such Common Stock issuable upon the conversion of such share of Nonvoting Common Stock immediately prior to such consolidation, merger, sale, or transfer or reclassification; provided, however, that no such shares of stock or other securities into which shares of Nonvoting Common Stock are so converted shall have any voting rights whatsoever. (d) LIQUIDATION. In the event of any voluntary or involuntary liquidation, dissolution, or winding up of the affairs of the Corporation, the holders of shares of Common Stock and Nonvoting Common Stock shall be entitled to share ratably, in accordance with the number of shares held by each such holder, in all of the assets of the Corporation available for distribution to the holders of shares of Common Stock.

Except as otherwise provided herein or by law, the entire voting power of the Corporation shall be vested in the holders of shares of Common Stock and each holder of shares of Common Stock shall be entitled to one vote for each share of Common Stock held of record by such holder; PROVIDED that, without the consent of the holders of record of at least 5l% of Nonvoting Common Stock at the time outstanding (assuming, for the purposes of this provision, that the holders of rights to acquire shares of Nonvoting Common Stock shall be deemed to be the holders of the shares of Nonvoting Common Stock which are at the time issuable upon the full exercise thereof whether or not such holders are then entitled to exercise such rights pursuant to the terms thereof), given in writing or by the vote at any regular or special meeting of stockholders of the Corporation, the Corporation shall not: 5 <Page> (i) amend, alter, modify, or repeal any provision of this Certificate of Incorporation or the By-Laws of the Corporation in any manner which adversely affects the relative rights, preferences, qualifications, powers, limitations or restrictions of the Nonvoting Common Stock, or amend, alter, modify, or repeal this Section 2(e); (ii) increase or decrease the authorized number of shares of any class of capital stock of the Corporation or authorize, issue, or otherwise create securities convertible into or exercisable for any shares of capital stock of the Corporation other than the shares of Common Stock and Nonvoting Common Stock authorized hereunder and the shares of Series A, Series B, and Series C Preferred Stock designated in that certain Certificate of the Powers, Designations, Preferences, and Rights of the Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock dated March 30, 1995; (iii) voluntarily effect an exchange or reclassification of shares of Nonvoting Common Stock into shares of another class of capital stock of the Corporation; or (iv) effect a merger or consolidation of the Corporation with another corporation, unless the certificate or articles of incorporation of the surviving corporation shall provide that the shares of the capital stock of such surviving corporation into which the shares of Nonvoting Common Stock hereunder shall be converted shall have the identical rights and privileges as the shares of capital stock of such surviving corporation into which the shares of Common Stock hereunder shall be converted, other than the voting rights in this Section 2(e) and the conversion and other rights in Section 3 below which shall not be adversely affected by such merger or consolidation. 3. CONVERSION. (a) RIGHT TO CONVERSION. Subject to and upon compliance with the provisions of this Section 3, any holder of shares of Nonvoting Common Stock shall be entitled at any time and from time to time to convert each share of Nonvoting Common Stock held by such holder into a share of Common Stock at the conversion rate of one share of Common Stock for one share of Nonvoting Common Stock. (b) PROCEDURE. The conversion of any shares of Nonvoting Common Stock into shares of Common Stock shall be effected by the holder of the shares of Nonvoting Common Stock to be converted surrendering the certificate therefor, duly endorsed, at the office of the Corporation or of any transfer agent for the shares of Common Stock or at such other place as the Corporation is willing to accept such surrender accompanied by written notice to the Corporation at such office or other place that it elects to so convert and stating the number of shares of 6 <Page> Nonvoting Common Stock being converted. Thereupon the Corporation shall promptly issue and deliver at such office or other place to such holder a certificate or certificates for the number of shares of Common Stock to which such holder is entitled, registered in the name of such holder or a designee of such holder as specified in such notice. Such conversion shall be deemed to have been made at the close of business on the date of such surrender of the shares to be converted in accordance with the procedure set forth in the first sentence of this Section 3(b) and the Person entitled to receive the shares issuable upon such conversion shall be treated for all purposes as having become the record holder of such shares at such time. In the event of the conversion of less than all of the shares of Nonvoting Common Stock into shares of Common Stock evidenced by the certificate so surrendered, the Corporation shall execute and deliver to or upon the written order of such holder, without charge to such holder, a new certificate evidencing the shares of Nonvoting Common Stock not converted. (c) RESERVATION. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, or any shares of Common Stock held in its treasury, solely for the purpose of issue upon conversion of the shares of Nonvoting Common Stock as provided herein, such number of shares of Common Stock as shall then be issuable upon the conversion of all outstanding shares of Nonvoting Common Stock. The shares of Common Stock so issuable shall when so issued be duly and validly issued, fully paid, and nonassessable. (d) CERTAIN LEGAL REQUIREMENTS. No person subject to the provisions of Regulation Y shall, and no such Person shall permit any of its Bank Holding Company Affiliates to, convert any shares of Nonvoting Common Stock held by it into shares of Common Stock, and the Corporation shall not be required to convert any such shares of Nonvoting Common Stock, if after giving effect to such conversion, (i) such Person and its Bank Holding Company Affiliates would own more than 5% of the total issued and outstanding shares of Common Stock or (ii) such Person would Control the Corporation (and, for purposes of this clause (ii), a reasoned opinion of counsel to such Person (which is based on facts and circumstances deemed appropriate by such counsel) to the effect that such Person does not control the Corporation shall be conclusive). 4.

Nothing contained in this Article Seventh shall be construed to relieve any Interested Stockholder from any fiduciary obligation imposed by law. SEVENTH: The Corporation shall indemnify any person who was, is, or is threatened to be made a party to a proceeding (as hereinafter defined) by reason of the fact that he or she (i) is or was a director or officer of the Corporation or (ii) while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, partner, venturer, proprietor, trustee, employee, agent, or similar functionary of another foreign or domestic corporation, partnership, joint venture, sole proprietorship, trust, employee benefit plan, or other enterprise, to the fullest extent permitted under the Delaware General Corporation Law, as the same exists or may 18 <Page> hereafter be amended. Such right shall be a contract right and as such shall run to the benefit of any director or officer who is elected and accepts the position of director or officer of the Corporation or elects to continue to serve as a director or officer of the Corporation while this Article Eighth is in effect. Any repeal or amendment of this Article Eighth shall be prospective only and shall not limit the rights of any such director or officer or the obligations of the Corporation with respect to any claim arising from or related to the services of such director or officer in any of the foregoing capacities prior to any such repeal or amendment to this Article Eighth. Such right shall include the right to be paid by the Corporation expenses incurred in investigating or defending any such proceeding in advance of its final disposition to the maximum extent permitted under the Delaware General Corporation Law, as the same exists or may hereafter be amended. If a claim for indemnification or advancement of expenses hereunder is not paid in full by the Corporation within sixty (60) days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim, and if successful in whole or in part, the claimant shall also be entitled to be paid the expenses of prosecuting such claim. It shall be a defense to any such action that such indemnification or advancement of costs of defense is not permitted under the Delaware General Corporation Law, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its board of directors or any committee thereof, independent legal counsel, or stockholders) to have made its determination prior to the commencement of such action that indemnification of, or advancement of costs of defense to, the claimant is permissible in the circumstances nor an actual determination by the Corporation (including its board of directors or any committee thereof, independent legal counsel, or stockholders) that such indemnification or advancement is not permissible shall be a defense to the action or create a presumption that such indemnification or advancement is not permissible. In the event of the death of any person having a right of indemnification under the foregoing provisions, such right shall inure to the benefit of his or her heirs, executors, administrators, and personal representatives. The rights conferred above shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, by-law, resolution of stockholders or directors, agreement, or otherwise. The Corporation may additionally indemnify any employee or agent of the Corporation to the fullest extent permitted by law. Without limiting the generality of the foregoing, to the extent permitted by then applicable law, the grant of mandatory indemnification pursuant to this Article Eighth shall extend to proceedings involving the negligence of such person. As used herein, the term "proceeding" means any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, arbitrative, or investigative, any appeal in such an action, suit, or proceeding, and any inquiry or investigation that could lead to such an action, suit, or proceeding. EIGHTH: A director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the 19 <Page> Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or knowing violation of law, (iii) under Section 174 of the Delaware General Corporation Law, or (iv) for any transaction from which the director derived an improper personal benefit. Any repeal or amendment of this Article Ninth by the stockholders of the Corporation shall be prospective only, and shall not adversely affect any limitation on the personal liability of a director of the Corporation arising from an act or omission occurring prior to the time of such repeal or amendment. In addition to the circumstances in which a director of the Corporation is not personally liable as set forth in the foregoing provisions of this Article Ninth, a director shall not be liable to the Corporation or its stockholders to such further extent as permitted by any law hereafter enacted, including without limitation any subsequent amendment to the Delaware General Corporation Law. NINTH: Whenever a compromise or arrangement is proposed between this Corporation and its creditors or any class of them and/or between this Corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of this Corporation or of any creditor or stockholder thereof or on the application of any receiver or receivers appointed for this Corporation under the provisions of Section 291 of Title 8 of the Delaware Code or on the application of trustees in dissolution or of any receiver or receivers appointed for this Corporation under the provisions of Section 279 of Title 8 of the Delaware Code, order a meeting of the creditors or class of creditors and/or of the stockholders or class of stockholders of this Corporation, as the case may be, to be summoned in such manner as the said court directs. If a majority in number representing three-fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of this Corporation, as the case may be, agree to any compromise or arrangement and to any reorganization of this Corporation as a consequence of such compromise or arrangement, the said compromise or arrangement and the said reorganization shall, if sanctioned by the court to which the said application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of this Corporation, as the case may be, and also on this Corporation. TENTH: Meetings of stockholders may be held within or without the State of Delaware, as the by-laws may provide. The books of the Corporation may be kept (subject to any provision contained in the statutes) outside the State of Delaware at such place or places as may be designated from time to time by the board of directors or in the by-laws of the Corporation. ELEVENTH: The Corporation reserves the right to amend, alter, change or repeal any provision contained in this certificate of incorporation, in the manner now or hereafter prescribed by statute, and all rights conferred upon stockholders herein are granted subject to this reservation. The foregoing and anything contained elsewhere in this certificate of incorporation to the contrary notwithstanding, the affirmative vote of the holders of at least eighty percent (80%) of the voting power of the then outstanding Voting Stock, voting together as a single class, shall be required to alter, amend, repeal, 20 <Page> or adopt any provision inconsistent with Article Sixth, Section 2; Article Sixth, Section 3; Article Sixth, Section 4; Article Sixth, Section 6; and Article Seventh. 21 <Page> IN WITNESS WHEREOF, the undersigned has duly executed this Second Restated Certificate of Incorporation on behalf of the Corporation as of the 19th day of March, 2002. UNITED STATIONERS INC. By: ------------------------------------------ Name: Deidra D.

DESIGNATION AND AMOUNT. The shares of such series shall be designated as "Series A Junior Preferred Stock" (the "Series A Preferred Stock") and the number of shares constituting such series shall be 68,000. Section 2. DIVIDENDS AND DISTRIBUTIONS. (A) Subject to the provisions for adjustment hereinafter set forth, and subject to the rights of the holders of any shares of any series of Preferred Stock ranking prior and superior to the Series A Preferred Stock with respect to dividends, the holders of shares of Series A Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, (i) cash dividends in an amount per share (rounded to the nearest cent) equal to 1,000 times the aggregate per share amount of all cash dividends declared or paid on the Common Stock, $0.10 par value per share, of the Company (the "Common Stock") and (ii) a preferential cash dividend (the "Preferential Dividends"), if any, in preference to the holders of Common Stock, on the first day of each fiscal quarter of the Company (each a "Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Series A Preferred Stock, payable in an amount (except in the case of the first Quarterly Dividend Payment if the date of the first issuance of Series A Preferred Stock is a date other than a Quarterly Dividend Payment date, in which case such payment shall be a prorated amount of such amount) equal to $0.001 per share of Series A Preferred Stock less the per share amount of all cash dividends declared on the Series A Preferred Stock pursuant to clause (i) of this sentence since the immediately preceding Quarterly Dividend Payment Date or, with 2 <Page> respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Series A Preferred Stock. In the event the Company shall, at any time after the issuance of any share or fraction of a share of Series A Preferred Stock, make any distribution on the shares of Common Stock of the Company, whether by way of a dividend or a reclassification of stock, a recapitalization, reorganization or partial liquidation of the Company or otherwise, which is payable in cash or any debt security, debt instrument, real or personal property or any other property (other than cash dividends subject to the immediately preceding sentence, a distribution of shares of Common Stock or other capital stock of the Company or a distribution of rights or warrants to acquire any such share, including any debt security convertible into or exchangeable for any such share, at a price less than the Fair Market Value (as hereinafter defined) of such share), then, and in each such event, the Company shall simultaneously pay on each then outstanding share of Series A Preferred Stock of the Company a distribution, in like kind, of 1,000 times such distribution paid on a share of Common Stock (subject to the provisions for adjustment hereinafter set forth). The dividends and distributions on the Series A Preferred Stock to which holders thereof are entitled pursuant to clause (i) of the first sentence of this paragraph and pursuant to the second sentence of this paragraph are hereinafter referred to as "Dividends" and the multiple of such cash and non-cash dividends on the Common Stock applicable to the determination of the Dividends, which shall be 1,000 initially but shall be adjusted from time to time as hereinafter provided, is hereinafter referred to as the "Dividend Multiple". In the event the Company shall at any time after August 16, 1999 declare or pay any dividend or 3 <Page> make any distribution on Common Stock payable in shares of Common Stock, or effect a subdivision or split or a combination, consolidation or reverse split of the outstanding shares of Common Stock into a greater or lesser number of shares of Common Stock, then in each such case the Dividend Multiple thereafter applicable to the determination of the amount of Dividends which holders of shares of Series A Preferred Stock shall be entitled to receive shall be the Dividend Multiple applicable immediately prior to such event multiplied by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. (B) The Company shall declare each Dividend at the same time it declares any cash or non-cash dividend or distribution on the Common Stock in respect of which a Dividend is required to be paid. No cash or non-cash dividend or distribution on the Common Stock in respect of which a Dividend is required to be paid shall be paid or set aside for payment on the Common Stock unless a Dividend in respect of such dividend or distribution on the Common Stock shall be simultaneously paid, or set aside for payment, on the Series A Preferred Stock. (C) Preferential Dividends shall begin to accrue on outstanding shares of Series A Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issuance of any shares of Series A Preferred Stock. Accrued but unpaid Preferential Dividends shall cumulate but shall not bear interest. Preferential Dividends paid on the shares of Series A Preferred Stock in an amount less than the total amount of 4 <Page> such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. Section 3. VOTING RIGHTS. The holders of shares of Series A Preferred Stock shall have the following voting rights: (A) Subject to the provisions for adjustment hereinafter set forth, each share of Series A Preferred Stock shall entitle the holder thereof to 1,000 votes on all matters submitted to a vote of the holders of the Common Stock. The number of votes which a holder of Series A Preferred Stock is entitled to cast, as the same may be adjusted from time to time as hereinafter provided, is hereinafter referred to as the "Vote Multiple". In the event the Company shall at any time after August 16, 1999 declare or pay any dividend on Common Stock payable in shares of Common Stock, or effect a subdivision or split or a combination, consolidation or reverse split of the outstanding shares of Common Stock into a greater or lesser number of shares of Common Stock, then in each such case the Vote Multiple thereafter applicable to the determination of the number of votes per share to which holders of shares of Series A Preferred Stock shall be entitled after such event shall be the Vote Multiple immediately prior to such event multiplied by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. (B) Except as otherwise provided herein, in the Certificate of Incorporation or by law, the holders of shares of Series A Preferred Stock and the holders 5 <Page> of shares of Common Stock shall vote together as one class on all matters submitted to a vote of stockholders of the Company. (C) In the event that the Preferential Dividends accrued on the Series A Preferred Stock for four or more quarterly dividend periods, whether consecutive or not, shall not have been declared and paid or irrevocably set aside for payment, the holders of record of Preferred Stock of the Company of all series (including the Series A Preferred Stock), other than any series in respect of which such right is expressly withheld by the Certificate of Incorporation or the authorizing resolutions included in any Certificate of Designations therefor, shall have the right, at the next meeting of stockholders called for the election of directors, to elect two members to the Board of Directors, which directors shall be in addition to the number required prior to such event, to serve until the next Annual Meeting and until their successors are elected and qualified or their earlier resignation, removal or incapacity or until such earlier time as all accrued and unpaid Preferential Dividends upon the outstanding shares of Series A Preferred Stock shall have been paid (or irrevocably set aside for payment) in full. The holders of shares of Series A Preferred Stock shall continue to have the right to elect directors as provided by the immediately preceding sentence until all accrued and unpaid Preferential Dividends upon the outstanding shares of Series A Preferred Stock shall have been paid (or set aside for payment) in full. Such directors may be removed and replaced by such stockholders, and vacancies in such directorships may be filled only by such stockholders (or by the remaining director elected by such stockholders, if there be one) in the manner permitted 6 <Page> by law; provided, however, that any such action by stockholders shall be taken at a meeting of stockholders and shall not be taken by written consent thereto. (D) Except as otherwise required by the Certificate of Incorporation or by law or set forth herein, holders of Series A Preferred Stock shall have no other special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for the taking of any corporate action. Section 4. CERTAIN RESTRICTIONS. (A) Whenever Preferential Dividends or Dividends are in arrears or the Company shall be in default of payment thereof, thereafter and until all accrued and unpaid Preferential Dividends and Dividends, whether or not declared, on shares of Series A Preferred Stock outstanding shall have been paid or set irrevocably aside for payment in full, and in addition to any and all other rights which any holder of shares of Series A Preferred Stock may have in such circumstances, the Company shall not: (i) declare or pay dividends on, make any other distributions on, or redeem or purchase or otherwise acquire for consideration, any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock; (ii) declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity as to dividends with the Series A Preferred Stock, unless dividends are paid ratably on the Series A Preferred Stock and all such parity stock on which dividends are payable 7 <Page> or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled if the full dividends accrued thereon were to be paid; (iii) except as permitted by subparagraph (iv) of this paragraph 4(A), redeem or purchase or otherwise acquire for consideration shares of any stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, provided that the Company may at any time redeem, purchase or otherwise acquire shares of any such parity stock in exchange for shares of any stock of the Company ranking junior (both as to dividends and upon liquidation, dissolution or winding up) to the Series A Preferred Stock; or (iv) purchase or otherwise acquire for consideration any shares of Series A Preferred Stock, or any shares of stock ranking on a parity with the Series A Preferred Stock (either as to dividends or upon liquidation, dissolution or winding up), except in accordance with a purchase offer made to all holders of such shares upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes. (B) The Company shall not permit any Subsidiary (as hereinafter defined) of the Company to purchase or otherwise acquire for consideration any shares of 8 <Page> stock of the Company unless the Company could, under paragraph (A) of this Section 4, purchase or otherwise acquire such shares at such time and in such manner. A "Subsidiary" of the Company shall mean any corporation or other entity of which securities or other ownership interests having ordinary voting power sufficient to elect a majority of the board of directors of such corporation or other entity or other persons performing similar functions are beneficially owned, directly or indirectly, by the Company or by any corporation or other entity that is otherwise controlled by the Company. (C) The Company shall not issue any shares of Series A Preferred Stock except upon exercise of Rights issued pursuant to that certain Rights Agreement dated as of July 27, 1999 between the Company and BANKBOSTON, N.A. as Rights Agent, as it may be amended from time to time, a copy of which is on file with the Secretary of the Company at its principal executive office and shall be made available to stockholders of record without charge upon written request therefor addressed to said Secretary. Notwithstanding the foregoing sentence, nothing contained in the provisions hereof shall prohibit or restrict the Company from issuing for any purpose any series of Preferred Stock with rights and privileges similar to, different from, or greater than, those of the Series A Preferred Stock. Section 5. REACQUIRED SHARES. Any shares of Series A Preferred Stock purchased or otherwise acquired by the Company in any manner whatsoever shall be retired and cancelled promptly after the acquisition thereof. All such shares upon their retirement and cancellation shall become authorized but unissued shares of Preferred 9 <Page> Stock, without designation as to series, and such shares may be reissued as part of a new series of Preferred Stock to be created by resolution or resolutions of the Board of Directors. Section 6. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, no distribution shall be made (i) to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock unless the holders of shares of Series A Preferred Stock shall have received for each share of Series A Preferred Stock, subject to adjustment as hereinafter provided, (A) $1,000 plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment or, (B) if greater than the amount specified in clause (i)(A) of this sentence, an amount equal to 1,000 times the aggregate amount to be distributed per share to holders of Common Stock, as the same may be adjusted as hereinafter provided and (ii) to the holders of stock ranking on a parity upon liquidation, dissolution or winding up with the Series A Preferred Stock, unless simultaneously therewith distributions are made ratably on the Series A Preferred Stock and all other shares of such parity stock in proportion to the total amounts to which the holders of shares of Series A Preferred Stock are entitled under clause (i)(A) of this sentence and to which the holders of such parity shares are entitled, in each case upon such liquidation, dissolution or winding up. The amount to which holders of Series A Preferred Stock may be entitled upon liquidation, dissolution or winding up of the Company pursuant to clause (i)(B) of the foregoing sentence is hereinafter referred to as 10 <Page> the "Participating Liquidation Amount" and the multiple of the amount to be distributed to holders of shares of Common Stock upon the liquidation, dissolution or winding up of the Company applicable pursuant to said clause to the determination of the Participating Liquidation Amount, as said multiple may be adjusted from time to time as hereinafter provided, is hereinafter referred to as the "Liquidation Multiple". In the event the Company shall at any time after August 16, 1999 declare or pay any dividend on Common Stock payable in shares of Common Stock, or effect a subdivision or split or a combination, consolidation or reverse split of the outstanding shares of Common Stock into a greater or lesser number of shares of Common Stock, then, in each such case, the Liquidation Multiple thereafter applicable to the determination of the Participating Liquidation Amount to which holders of Series A Preferred Stock shall be entitled after such event shall be the Liquidation Multiple applicable immediately prior to such event multiplied by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. Section 7. CERTAIN RECLASSIFICATIONS AND OTHER EVENTS. (A) In the event that holders of shares of Common Stock of the Company receive after August 16, 1999 in respect of their shares of Common Stock any share of capital stock of the Company (other than any share of Common Stock of the Company), whether by way of reclassification, recapitalization, reorganization, dividend or other distribution or otherwise (a "Transaction"), then, and in each such event, the 11 <Page> dividend rights, voting rights and rights upon the liquidation, dissolution or winding up of the Company of the shares of Series A Preferred Stock shall be adjusted so that after such event the holders of Series A Preferred Stock shall be entitled, in respect of each share of Series A Preferred Stock held, in addition to such rights in respect thereof to which such holder was entitled immediately prior to such adjustment, to (i) such additional dividends as equal the Dividend Multiple in effect immediately prior to such Transaction multiplied by the additional dividends which the holder of a share of Common Stock shall be entitled to receive by virtue of the receipt in the Transaction of such capital stock, (ii) such additional voting rights as equal the Vote Multiple in effect immediately prior to such Transaction multiplied by the additional voting rights which the holder of a share of Common Stock shall be entitled to receive by virtue of the receipt in the Transaction of such capital stock and (iii) such additional distributions upon liquidation, dissolution or winding up of the Company as equal the Liquidation Multiple in effect immediately prior to such Transaction multiplied by the additional amount which the holder of a share of Common Stock shall be entitled to receive upon liquidation, dissolution or winding up of the Company by virtue of the receipt in the Transaction of such capital stock, as the case may be, all as provided by the terms of such capital stock. (B) In the event that holders of shares of Common Stock of the Company receive after August 16, 1999 in respect of their shares of Common Stock any right or warrant to purchase Common Stock (including as such a right, for all purposes of this paragraph, any security convertible into or exchangeable for Common Stock) at a purchase price per share less than the Fair Market Value of a share of Common Stock on 12 <Page> the date of issuance of such right or warrant, then and in each such event the dividend rights, voting rights and rights upon the liquidation, dissolution or winding up of the Company of the shares of Series A Preferred Stock shall each be adjusted so that after such event the Dividend Multiple, the Vote Multiple and the Liquidation Multiple shall each be the product of the Dividend Multiple, the Vote Multiple and the Liquidation Multiple, as the case may be, in effect immediately prior to such event multiplied by a fraction the numerator of which shall be the number of shares of Common Stock outstanding immediately before such issuance of rights or warrants plus the maximum number of shares of Common Stock which could be acquired upon exercise in full of all such rights or warrants and the denominator of which shall be the number of shares of Common Stock outstanding immediately before such issuance of rights or warrants plus the number of shares of Common Stock which could be purchased, at the Fair Market Value of the Common Stock at the time of such issuance, by the maximum aggregate consideration payable upon exercise in full of all such rights or warrants. (C) In the event that holders of shares of Common Stock of the Company receive after August 16, 1999 in respect of their shares of Common Stock any right or warrant to purchase capital stock of the Company (other than shares of Common Stock), including as such a right, for all purposes of this paragraph, any security convertible into or exchangeable for capital stock of the Company (other than Common Stock), at a purchase price per share less than the Fair Market Value of such shares of capital stock on the date of issuance of such right or warrant, then and in each such event the dividend rights, voting rights and rights upon liquidation, dissolution or winding up of 13 <Page> the Company of the shares of Series A Preferred Stock shall each be adjusted so that after such event each holder of a share of Series A Preferred Stock shall be entitled, in respect of each share of Series A Preferred Stock held, in addition to such rights in respect thereof to which such holder was entitled immediately prior to such event, to receive (i) such additional dividends as equal the Dividend Multiple in effect immediately prior to such event multiplied, first, by the additional dividends to which the holder of a share of Common Stock shall be entitled upon exercise of such right or warrant by virtue of the capital stock which could be acquired upon such exercise and multiplied again by the Discount Fraction (as hereinafter defined) and (ii) such additional voting rights as equal the Vote Multiple in effect immediately prior to such event multiplied, first, by the additional voting rights to which the holder of a share of Common Stock shall be entitled upon exercise of such right or warrant by virtue of the capital stock which could be acquired upon such exercise and multiplied again by the Discount Fraction and (iii) such additional distributions upon liquidation, dissolution or winding up of the Company as equal the Liquidation Multiple in effect immediately prior to such event multiplied, first, by the additional amount which the holder of a share of Common Stock shall be entitled to receive upon liquidation, dissolution or winding up of the Company upon exercise of such right or warrant by virtue of the capital stock which could be acquired upon such exercise and multiplied again by the Discount Fraction. For purposes of this paragraph, the "Discount Fraction" shall be a fraction the numerator of which shall be the difference between the Fair Market Value of a share of the capital stock subject to a right or warrant distributed to holders of shares of Common Stock of the Company as contemplated by 14 <Page> this paragraph immediately after the distribution thereof and the purchase price per share for such share of capital stock pursuant to such right or warrant and the denominator of which shall be the Fair Market Value of a share of such capital stock immediately after the distribution of such right or warrant. (D) For purposes of this Certificate of Designations, the "Fair Market Value" of a share of capital stock of the Company (including a share of Common Stock) on any date shall be deemed to be the average of the daily closing price per share thereof over the 30 consecutive Trading Days (as such term is hereinafter defined) immediately prior to such date; PROVIDED, HOWEVER, that, in the event that such Fair Market Value of any such share of capital stock is determined during a period which includes any date that is within 30 Trading Days after (i) the ex-dividend date for a dividend or distribution on stock payable in shares of such stock or securities convertible into shares of such stock, or (ii) the effective date of any subdivision, split, combination, consolidation, reverse stock split or reclassification of such stock, then, and in each such case, the Fair Market Value shall be appropriately adjusted by the Board of Directors of the Company to take into account ex-dividend or post-effective date trading. The closing price for any day shall be the last sale price, regular way, or, in case, no such sale takes place on such day, the average of the closing bid and asked prices, regular way (in either case, as reported in the applicable transaction reporting system with respect to securities listed or admitted to trading on the Nasdaq National Market), or, if the shares are not listed or admitted to trading on the Nasdaq National Market, as reported in the applicable transaction reporting system with respect to securities listed on the principal national securities exchange or 15 <Page> Nasdaq market on which the shares are listed or admitted to trading or, if the shares are not listed or admitted to trading on any national securities exchange or Nasdaq market, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by the National Association of Securities Dealers, Inc. Automated Quotation System ("NASDAQ") or such other system then in use, or if on any such date the shares are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the shares selected by the Board of Directors of the Company. The term "Trading Day" shall mean a day on which the principal national securities exchange or Nasdaq market on which the shares are listed or admitted to trading is open for the transaction of business or, if the shares are not listed or admitted to trading on any national securities exchange or Nasdaq market, on which the Nasdaq National Market or such other national securities exchange as may be selected by the Board of Directors of the Company is open. If the shares are not publicly held or not so listed or traded on any day within the period of 30 Trading Days applicable to the determination of Fair Market Value thereof as aforesaid, "Fair Market Value" shall mean the fair market value thereof per share as determined in good faith by the Board of Directors of the Company. In either case referred to in the foregoing sentence, the determination of Fair Market Value shall be described in a statement filed with the Secretary of the Company. Section 8. CONSOLIDATION, MERGER, ETC. In case the Company shall enter into any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or 16 <Page> any other property, then in any such case each outstanding share of Series A Preferred Stock shall at the same time be similarly exchanged for or changed into the aggregate amount of stock, securities, cash and/or other property (payable in like kind), as the case may be, for which or into which each share of Common Stock is changed or exchanged multiplied by the highest of the Vote Multiple, the Dividend Multiple or the Liquidation Multiple in effect immediately prior to such event. Section 9. EFFECTIVE TIME OF ADJUSTMENTS. (A) Adjustments to the Series A Preferred Stock required by the provisions hereof shall be effective as of the time at which the event requiring such adjustments occurs. (B) The Company shall give prompt written notice to each holder of a share of Series A Preferred Stock of the effect of any adjustment to the voting rights, dividend rights or rights upon liquidation, dissolution or winding up of the Company of such shares required by the provisions hereof. Notwithstanding the foregoing sentence, the failure of the Company to give such notice shall not affect the validity of or the force or effect of or the requirement for such adjustment. Section 10. NO REDEMPTION. The shares of Series A Preferred Stock shall not be redeemable at the option of the Company or any holder thereof. Notwithstanding the foregoing sentence of this Section, the Company may acquire shares of Series A Preferred Stock in any other manner permitted by law, the provisions hereof and the Certificate of Incorporation of the Company. 17 <Page> Section 11. RANKING. Unless otherwise provided in the Certificate of Incorporation of the Company or a Certificate of Designations relating to a subsequent series of preferred stock of the Company, the Series A Preferred Stock shall rank junior to all other series of the Company's Preferred Stock as to the payment of dividends and the distribution of assets on liquidation, dissolution or winding up and senior to the Common Stock. Section 12. AMENDMENT. The provisions hereof and the Certificate of Incorporation of the Company shall not be amended in any manner which would adversely affect the rights, privileges or powers of the Series A Preferred Stock without, in addition to any other vote of stockholders required by law, the affirmative vote of the holders of two-thirds or more of the outstanding shares of Series A Preferred Stock, voting together as a single class. 18
