Notwithstanding the fixing of the number of shares constituting a particular series upon the issuance thereof, the Board of Directors may at any time thereafter authorize the issuance of additional shares of the same series or may reduce the number of shares constituting such series (but not below the number of shares thereof then outstanding).

An existing certificate of Designation designating a series of preferred stock is annexed hereto.

FIFTH. (1) The business and affairs of the Corporation shall be managed under the direction of the Board of Directors consisting of not less than three (3) nor more than eleven (11) directors. The exact number of directors within the minimum and maximum limitations specified in the preceding sentence shall be fixed and determined from time to time by resolution adopted by the vote of a majority of the total number of directors.

(2) The Board of Directors shall be divided into three classes:
Class I, Class II and Class III, which shall be as nearly equal in number as possible.

(3) In the event of any increase or decrease in the authorized number of directors, (a) each director than serving as such shall nevertheless continue as a director of the class of which he is a member until the expiration of his current term, or his earlier resignation, retirement, removal from office, disqualification or death, and (b) 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 maintain such classes as nearly equal as possible.

(4) Notwithstanding any of the foregoing provisions of this Article FIFTH, each director shall serve until his successor is elected and qualified or until his earlier resignation, retirement, removal from office, disqualification or death.

(5) Should a vacancy occur or be created, whether arising through resignation, retirement, removal from office, disqualification or death or through an increase in the number of directors, such vacancy shall be filled by the affirmative vote of at least a majority of the directors remaining in office, though they constitute less than a quorum of the Board of Directors and directors so chosen shall hold office for a term expiring at the annual meeting of stockholders at which the term of the class to which they have been elected expires.

(6) Any director or the entire Board of Directors may be removed from office at any time, but only for cause and only by the affirmative vote of the holders of at least 66-2/3% of the outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors.

(7) Notwithstanding any other provision of this Restated Certificate of Incorporation or any other provision of law which might otherwise permit a lesser vote or no vote, but in addition to any affirmative vote of the holders of any particular class or series of the capital stock of the Corporation required by law, this Restated Certificate of Incorporation or any designation of Preferred Stock, the affirmative vote of the holders of at least 66-2/3% of the combined voting power of the Corporation's outstanding voting securities, voting together as a single class, shall be required to alter, amend or repeal this Article FIFTH.

SIXTH. In furtherance and not in limitation of the powers conferred by law, the Board of Directors is expressly authorized to make, alter, amend and repeal the By-laws of the Corporation, subject to the power of the holders of the capital stock of the Corporation to alter, amend or repeal the By-laws; provided, however, that with respect to the power of the holders of the capital stock of the Corporation to alter, amend or repeal the By-laws of the Corporation, notwithstanding any other provision of this Restated Certificate of Incorporation or any provision of law which might otherwise permit a lesser vote or no vote, but in addition to any affirmative vote of the holders of any particular class or series of the capital stock of the Corporation required by law, this Restated Certificate of Corporation or any designation of Preferred Stock, the affirmative vote of the holders of at least 66-2/3% of the combined voting power of the Corporation's outstanding voting securities, voting together as a single class, shall be required to (i) alter, amend or repeal any provision of the By-laws, or (ii) alter, amend or repeal any provision of this Article SIXTH.

SEVENTH. Subject to the rights of the holders of any series of Preferred Stock with respect to such series of Preferred Stock, (A) any action required or permitted to be taken by the stockholders of the Corporation must be effected at an annual or special meeting of stockholders of the Corporation and may not be effected by any consent in writing by such stockholders and (B) special meetings of stockholders of the Corporation may be called only by the Board of Directors of the Corporation or the Executive Committee of the Board of Directors. The stockholders of the Corporation may not call a special meeting of stockholders of the Corporation or require the Board of Directors or Executive Committee of the Board of Directors to call a special meeting of the stockholders of the Corporation. The Board of Directors or the

Executive Committee of the Board of Directors may call a special meeting of stockholders of the Corporation only by giving written notice to the stockholders of the Corporation. Such notice must specify the purpose or purposes for which the meeting is called. The stockholders of the Corporation may not submit any matters or proposals for consideration at any special meeting. Notwithstanding any other provision of this Restated Certificate of Incorporation or any provision of law which might otherwise permit a lesser vote or no vote, but in addition to any affirmative vote of the holders of any particular class or series of the capital stock of the Corporation required by law, this Restated Certificate of Incorporation or any designation of Preferred Stock, the affirmative vote of the holders of at least 66-2/3% of the combined voting power of the Corporation's outstanding voting securities, voting together as a single class, shall be required to alter, amend or repeal this Article SEVENTH.

(e) any reclassification of securities (including any reverse stock split), or recapitalization or reorganization of the Corporation, or any merger or consolidation of the Corporation with any of its Subsidiaries, or any other transaction (whether or not with or into or otherwise involving any Interested Stockholder), that in any such case has the effect, directly or indirectly, of increasing the proportionate share of the outstanding shares of any class or series of stock or securities convertible into stock of the Corporation or any

Subsidiary that is directly or indirectly beneficially owned by any Interested Stockholder or any Affiliate or Associate of any Interested Stockholder; or

(f) any agreement, contract or other arrangement providing directly or indirectly for any of the foregoing;

shall not be consummated without the affirmative vote of the holders of at least 66-2/3% of the combined voting power of the Corporation's voting securities ("Voting Stock") then outstanding voting together as a single class.

provided, however, that, as used in the foregoing calculations, all prices per share shall be adjusted to reflect any subsequent stock splits, stock dividends or other similar corporate actions;

(ii) the transaction constituting the Business Combination shall provide for a consideration to be received by holders of any class or series of outstanding Voting Stock other than Common Stock in exchange for all their shares of such Voting Stock, and the aggregate amount of the cash and the Fair Market Value as of the date of the consummation of the Business Combination of any consideration other than cash to be received per share by holders of shares of such Voting Stock in such Business Combination shall be at least equal to the highest of the following (it being intended that the requirements of this paragraph (b)(ii) shall be required to be met with respect to every class and series of such outstanding Voting Stock, whether or not the Interested Stockholder beneficially owns any shares of a particular class or series of Voting Stock):

(B) (if applicable) the highest preferential amount per share to which the holders of shares of such class or series of Voting Stock are entitled in the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation regardless of whether the Business Combination to be consummated constitutes such an event; and

(C) the Fair Market Value per share of such class or series of Voting Stock on the Announcement Date or on the Determination Date, whichever is higher, multiplied by the ratio of (I) the highest per share price (including brokerage commissions, transfer taxes and soliciting dealers' fees) paid in

(iii) the consideration to be received by holders of a particular class or series of outstanding Voting Stock (including Common Stock) shall be in cash or in the same form as was previously paid in order to acquire shares of such class or series of Voting Stock that are beneficially owned by the Interested Stockholder, and if the Interested Stockholder beneficially owns shares of any class or series of Voting Stock that were acquired with varying forms of consideration, the form of consideration to be received by holders of such class or series of Voting Stock shall be either cash or the form used to acquire the largest number of shares of such class or series of Voting Stock beneficially owned by it;

(B) within the two years prior to the Announcement Date except as approved by a majority of the Disinterested Directors, there shall have been no failure to declare and pay at the regular dates therefor the full amount of any dividends (whether or not cumulative) payable on the outstanding Preferred Stock or class or series of stock having a preference over the Common Stock as to dividends or upon liquidation;

(C) within the two years prior to the Announcement Date there shall have been (I) no reduction in the annual rate of dividends paid on the Common Stock (except as necessary to reflect any subdivision of the Common Stock), except

as approved by a majority of the Disinterested Directors, and (II) an increase in such annual rate of dividends (as necessary to prevent any such reduction) in the event of any reclassification (including any reverse stock split), recapitalization, reorganization or any similar transaction that has the effect of reducing the number of outstanding shares of the Common Stock, unless the failure so to increase such annual rate is approved by a majority of the Disinterested Directors; and

(D) such Interested Stockholder shall not have become the beneficial owner of any additional shares of Voting Stock or securities convertible into or exchangeable for Voting Stock, except as part of the transaction that resulted in such Interested Stockholder becoming an Interested Stockholder;

(v) after such Interested Stockholder has become an Interested Stockholder, such Interested Stockholder shall not have (A) received the benefit, directly or indirectly (except proportionately as a stockholder and except in the ordinary course of business or as part of a supplier/customer relationship), of any loans, advances, guarantees, pledges or other financial assistance or any tax credits or other tax advantages provided by the Corporation, whether in anticipation of or in connection with such Business Combination or otherwise, (B) made any major change in the Corporation's business or equity capital structure without the unanimous approval of the Disinterested Directors, or (C) used any asset of the Corporation as collateral, or compensating balances, directly or indirectly, for any obligation of such Interested Stockholder; and

CERTIFICATE OF DESIGNATION, PREFERENCES AND RIGHTS OF

8% CUMULATIVE CONVERTIBLE PREFERRED STOCK OF

CENTURY ALUMINUM COMPANY

SECTION 1. Designation, Amount and Par Value. The series of Preferred Stock shall be designated as the 8% Cumulative Convertible Preferred Stock (the "Preferred Stock"), and the number of shares so designated shall be 500,000. The par value of each share of Preferred Stock shall be $0.01. Each share of Preferred Stock shall have a stated value of $50.00 per share (the "Stated Value").

SECTION 2. Dividends.

(a) Holders of Preferred Stock shall be entitled to receive and the Company shall pay, when, as and if declared by the Board of Directors out of funds legally available therefor, cumulative cash dividends at the rate per share (as a percentage of the Stated Value per share) equal to 8% per annum, payable quarterly in arrears on each March 31, June 30, September 30 and December 31 (each, a "Dividend Payment Date") and on the Conversion Date (as hereinafter defined). Dividends on the Preferred Stock shall accrue daily commencing on the Original Issue Date (as defined in Section 7) and shall be deemed to accrue whether or not earned or declared and whether or not there are profits, surplus or other funds of the Company legally available for the payment of dividends. The person that is shown on the Company's records as the holder of the Preferred Stock on an applicable record date (the "Holder") for any dividend payment will be entitled to receive such dividend payment and any other accrued and unpaid dividends which accrued prior to such Dividend Payment Date, without regard to any sale or disposition of such Preferred Stock subsequent to the applicable record date but prior to the applicable Dividend Payment Date. Except as otherwise provided herein, if at any time the Company pays less than the total amount of dividends then accrued on the Preferred Stock, such payment shall be distributed ratably among the Holders of the Preferred Stock based upon the number of shares held by each Holder.

(b) So long as any Preferred Stock shall remain outstanding, unless all accrued dividends payable on the Preferred Stock for all prior Dividend Payment Dates shall have been paid, neither the Company nor any subsidiary thereof shall redeem, purchase or otherwise acquire, directly or indirectly, any Common Stock (as defined in Section 5) or any shares of any other capital stock of the Company, ranking junior to the Preferred Stock in respect of dividends or liquidation preference, except the repurchase of shares of capital stock of the Company held by officers, directors or employees or former officers, directors or employees (or their estates or beneficiaries), upon death, disability, retirement, severance or termination of employment, or in order to satisfy tax withholding obligations of such persons upon the exercise of options or the vesting of performance shares or pursuant to any agreement under which such shares were issued, nor shall the Company directly or indirectly pay or declare any cash dividend or make any cash distribution (other than a dividend or distribution described in Section 5) upon, nor shall any cash distribution be made in respect of, any Common Stock or any other capital stock of the Company ranking junior to the Preferred Stock in respect of dividends or liquidation preference, nor shall any monies be set aside for or applied to the purchase or redemption (through a sinking fund or otherwise) of any Common Stock or any shares of any other capital

stock of the Company, ranking junior to the Preferred Stock in respect of dividends or liquidation preference, except as described above.

SECTION 3. Voting Rights. Except as otherwise provided herein and as otherwise provided by law, the Preferred Stock shall have no voting rights. So long as any shares of Preferred Stock are outstanding, the Company shall not, without the affirmative vote of the Holders of a majority of the shares of Preferred Stock then outstanding, (i) alter or change adversely the powers, preferences or rights given to the Preferred Stock, through an amendment to the Company's Certificate of Incorporation or otherwise, (ii) authorize or create any class of stock ranking as to dividends or distribution of assets upon a Liquidation (as defined below) senior to, prior to or pari passu with the Preferred Stock, or (iii) reorganize or reclassify the capital stock of the Company or merge or consolidate with or into any other company or entity.

SECTION 4. Liquidation. Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary (a "Liquidation"), the Holders of shares of Preferred Stock shall be entitled to receive out of the assets of the Company, whether such assets are capital or surplus, for each share of Preferred Stock an amount equal to the Stated Value, plus an amount equal to the then accrued but unpaid dividends per share, whether declared or not, but without interest ("Liquidation Preference"), before any distribution or payment shall be made to the holders of Common Stock or any other capital stock of the Company junior in respect of distribution of assets, and if the assets of the Company shall be insufficient to pay in full such amounts, then the entire assets to be distributed shall be distributed among the Holders of Preferred Stock ratably in accordance with the respective amounts that would be payable on such shares if all amounts payable thereon were paid in full. A sale, conveyance or disposition of all or substantially all of the assets of the Company, other than to a domestic subsidiary of the Company, shall be deemed a Liquidation; however, a consolidation or merger of the Company with or into any other company or companies shall not be treated as a Liquidation, but instead shall be subject to the provisions of Section 5. The Company shall mail written notice of any such Liquidation, not less than 30 days prior to the payment date stated therein, to each record Holder of Preferred Stock.

SECTION 5. Conversion.

(a) Right to Convert. Each Holder of the Preferred Stock shall have the right at any time and from time to time, at the option of such Holder, to convert any or all Preferred Stock held by such Holder, into such number of fully paid, validly issued and nonassessable shares of common stock, par value $0.01 per share, of the Company ("Common Stock"), free and clear of any liens, claims or encumbrances created by the Company, as is determined by dividing (i) the Liquidation Preference times the number of shares of Preferred Stock being converted ("Conversion Amount"), by (ii) the applicable Conversion Price (determined as hereinafter provided) in effect on the Conversion Date. immediately following such conversion, the rights of the Holders of converted Preferred Stock shall cease and the persons entitled to receive the Common Stock upon the conversion of Preferred Stock shall be treated for all purposes as then having become the owners of such Common Stock. The right to convert any shares of Preferred Stock called for redemption under Section 6 shall continue until and shall expire at 4:30 New York time on the last business day prior to the redemption date. Any conversion of Preferred Stock by any Holder shall be of a minimum number of 1,000 shares of Preferred Stock, except in the event that any Holder holds less than 1,000 shares of

Preferred Stock, in which case, all such shares held by such Holder may be converted.

(b) Mechanics of Conversion. To convert Preferred Stock into Common Stock, the Holder shall give written notice ("Conversion Notice") to the Company (which Conversion Notice may be given by facsimile transmission no later than the Conversion Date) stating that such Holder elects to convert the same and shall state therein the number of shares of Preferred Stock to be converted and the name or names in which such holder wishes the certificate or certificates for Common Stock to be issued (the conversion date specified in such Conversion Notice shall be referred to herein as the "Conversion Date"). As soon as possible after delivery of the Conversion Notice, such Holder shall surrender the certificate or certificates representing the Preferred Stock being converted, duly endorsed, at the office of the Company or, if identified in writing to all the Holders by the Company, at the offices of any transfer agent for the Preferred Stock. The Company shall, upon receipt of such Conversion Notice, issue and deliver to or upon the order of such Holder, against delivery of the certificates representing the Preferred Stock which have been converted, a certificate or certificates for the number of shares of Common Stock to which such Holder shall be entitled (with the number of and denomination of such certificates designated by such Holder), and the Company shall immediately issue and deliver to such Holder a certificate or certificates for the number of shares of Preferred Stock (including any fractional shares) which such Holder has not yet elected to convert hereunder but which are evidenced in part by the certificate(s) delivered to the Company in connection with such Conversion Notice. The Company shall not be obligated to issue certificates evidencing the shares of Common Stock issuable upon such conversion unless certificates evidencing such shares of the Preferred Stock being converted are either delivered to the Company or its transfer agent or the Holder notifies the Company or any such transfer agent that such certificates have been lost, stolen or destroyed and executes an agreement reasonably satisfactory to the Company to indemnify the Company from any loss incurred by it in connection therewith. In lieu of delivering physical certificates representing the Common Stock issuable upon conversion of Preferred Stock, provided the Company's transfer agent is participating in the Depository Trust Company ("DTC") Fast Automated Securities Transfer program, upon request of the Holder, the Company shall use its best efforts to cause its transfer agent to electronically transmit the Common Stock issuable upon conversion to the Holder, by crediting the account of the Holder's prime broker with DTC through its Deposit Withdrawal Agent Commission ("DWAC") system. The parties agree to coordinate with DTC to accomplish this objective. The conversion pursuant to this Section 5 shall be deemed to have been made immediately prior to the close of business on the Conversion Date. The person or persons entitled to receive the Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such Common Stock at the close of business on the Conversion Date. The Company's obligation to issue Common Stock upon conversion of Preferred Stock shall, except with respect to the Holder's compliance with the notice and delivery requirements set forth above in this Section 5(b), be absolute, is independent of any covenant of the Holder of Preferred Stock, and shall not be subject to: (i) any offset or defense, or (ii) any claims against the Holders of Preferred Stock whether pursuant to this Certificate of Designation, the Purchase Agreement (as defined in Section 7) or otherwise. In the event that the Company disputes the Holder's computation of the number of shares of Common Stock to be received, then the Company shall deliver to the Holder the number of shares of Common Stock not in dispute and shall seek to mutually agree with the Holder in good faith on the correct number of shares to be received.

(c) Determination of Conversion Price. The Conversion Price applicable with respect to the Preferred Stock (the "Conversion Price"), subject to the adjustments set forth below, shall be $17.92 per share.

(d) Stock Splits; Dividends; Adjustments.

(i) If the Company, at any time while the Preferred Stock is outstanding shall, (A) pay a stock dividend or otherwise make a distribution or distributions on any equity securities (including instruments or securities convertible into or exchangeable for such equity securities) in shares of Common Stock, (B) subdivide outstanding Common Stock into a larger number of shares, or (C) combine outstanding Common Stock into a smaller number of shares, then the Conversion Price shall be multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately before such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section 5(d)(i) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination.

(ii) In the event that the Company issues or sells any Common Stock or securities which are convertible into or exchangeable for its Common Stock (other than the Preferred Stock), or any warrants or other rights to subscribe for or to purchase or any options for the purchase of its Common Stock ("Convertible Securities") (other than shares or options issued or which may be issued pursuant to (A) the Company's current or future employee or director stock incentive or option plans or shares issued upon exercise of options, warrants or rights or upon the vesting of performance shares outstanding on the date of the Purchase Agreement and listed in the Company's most recent periodic report filed under the Securities Exchange Act of 1934, as amended, (B) arrangements with the Holders of Preferred Stock, or (C) upon the conversion of the Preferred Stock) ("Exempted Issuances") at an effective purchase price per share which is less than the Per Share Market Value (as defined in Section 7) of the Common Stock on the Trading Day next preceding such issue or sale or, in the case of issuances to holders of its Common Stock, the record date fixed for the determination of stockholders entitled to receive Common Stock or Convertible Securities (the "Fair Market Price"), the Conversion Price in effect immediately prior to such issue or sale or record date, as applicable, shall be reduced effective concurrently with such issue or sale to an amount determined by multiplying the Conversion Price then in effect by a fraction, (1) the numerator of which shall be the sum of (x) the number of shares of Common Stock outstanding immediately prior to such issue or sale and (y) the number of shares of Common Stock which the aggregate consideration received by the Company for such additional shares would purchase at the Fair Market Price, and (2) the denominator of which shall be the number of shares of Common Stock and Convertible Securities of the Company outstanding immediately after such issue or sale. For the purposes of the foregoing adjustment, shares of Common Stock owned by or held on account of the Company or any subsidiary shall not be deemed outstanding for the purpose of any such computation. In addition, for the purposes of the foregoing adjustment, in the case of the

issuance of any Convertible Securities, the maximum number of shares of Common Stock issuable upon exercise, exchange or conversion of such Convertible Securities shall be deemed to be outstanding, and the aggregate consideration received by the Company for the issuance or sale of such Convertible Securities shall be deemed to include any consideration that would be received by the Company in connection with the exercise, exchange or conversion of such Convertible Securities, provided that no further adjustment shall be made upon the actual issuance of Common Stock upon exercise, exchange or conversion of such Convertible Securities. However, upon the expiration of any right or warrant to purchase Common Stock the issuance of which resulted in an adjustment in the Conversion Price designated in Section 5(c) pursuant to this Section 5(d)(ii), if any such right or warrant shall expire and shall not have been exercised, the Conversion Price designated in Section 5(c) shall immediately upon such expiration be recomputed and effective immediately upon such expiration be increased to the price which it would have been (but reflecting any other adjustments in the Conversion Price made pursuant to the provisions of this
Section 5 after the issuance of such rights or warrants) had the adjustment of the Conversion Price made upon the issuance of such rights or warrants been made on the basis of offering for subscription or purchase only that number of shares of Common Stock actually purchased upon the exercise of such rights or warrants actually exercised.

(iii) If the Company, at any time while the Preferred Stock is outstanding, shall distribute to all holders of Common Stock evidence of its indebtedness or assets or cash (other than ordinary cash dividends) or rights or warrants to subscribe for or purchase any security of the Company or any of its subsidiaries (excluding those referred to in Sections 5(d)(i) or 5(d)(ii) above), then concurrently with such distributions to holders of Common Stock, the Company shall distribute to Holders of the Preferred Stock, the amount of such indebtedness, assets, cash or rights or warrants which the Holders of Preferred Stock would have received had they converted all their Preferred Stock into Common Stock immediately prior to the record date for such distribution.

(iv) All calculations under this Section 5 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be.

(v) Whenever the Conversion Price is adjusted pursuant to this
Section 5(d), the Company shall promptly mail to each Holder of Preferred Stock a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

(vi) No adjustment in the Conversion Price shall reduce the Conversion Price below the then par value of the Common Stock.

(vii) The Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least 20 Trading Days and if the reduction is irrevocable during the period. Whenever the Conversion Price is reduced, the Company shall mail to the Holders of Preferred Stock a notice of the reduction. The Company shall mail, first class, postage prepaid, the notice at least 15 days before the date the reduced Conversion Price takes effect. The notice shall state the reduced

Conversion Price and the period it will be in effect. A reduction of the Conversion Price does not change or adjust the Conversion Price otherwise in effect for purposes of Section 5(d)(i), (ii), or (iii).

(viii) If:

A. In the event of any taking by the Company of a record date of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, any security or right convertible into or entitling the holder thereof to receive additional shares of Common Stock, or any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right; or

B. The Company shall declare a special nonrecurring cash dividend on or a redemption of its Common Stock; or

C. The approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock of the Company (other than a subdivision or combination of the outstanding shares of Common Stock), any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property; or

D. The Company shall authorize the voluntary or involuntary dissolution, liquidation or winding-up of the affairs of the Company;

then the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of Preferred Stock, and shall cause to be mailed to the Holders of Preferred Stock at their last addresses as they shall appear upon the stock books of the Company, at least 15 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, share exchange, dissolution, liquidation or winding-up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, share exchange, dissolution, liquidation or winding-up; provided, however, that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice.

(e) Reorganization, Merger or Going Private. In case of any reorganization or reclassification of the capital stock of the Company, any consolidation or merger of the Company with or into another person, any compulsory share exchange pursuant to which the Common Stock is converted into other securities, cash or property or a "going private" transaction under Rule 13e-3 promulgated pursuant to the Exchange Act, the Holders of the Preferred Stock then outstanding shall be deemed to have converted their Preferred Stock into Common Stock immediately prior to such reorganization, reclassification, consolidation, merger, or share exchange and shall have the right thereafter to convert such shares only into the shares of stock and other securities and property receivable upon or deemed to be held by holders of Common Stock following such reorganization, reclassification, consolidation, merger or share exchange, and the Holders of the Preferred Stock shall be entitled upon such event to receive such amount of securities or property as the shares of the Common Stock of the Company into which such shares of Preferred Stock could have been converted immediately prior to such reorganization, reclassification, consolidation, merger or share exchange would have been entitled. The terms of any such reorganization, reclassification, consolidation, merger or share exchange shall include such terms so as to continue to give to the Holder of Preferred Stock the right to receive the securities or property set forth in this Section 5(e) upon any conversion following such reorganization, reclassification, consolidation, merger or share exchange. This provision shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, or share exchanges.

(f) Other Actions. The Company will not avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company and will at all times in good faith assist in the carrying out of all of the provisions of this Section 5 and in the taking of all action as may be necessary or appropriate in order to protect the conversion rights of the Holders of the Preferred Stock against impairment.

(g) Reservation of Shares. The Company covenants that it will at all times reserve and keep available out of its authorized and unissued Common Stock solely for the purpose of issuance upon conversion of Preferred Stock as herein provided, free from preemptive rights or any other contingent purchase rights of persons other than the Holders of Preferred Stock, such number of shares of Common Stock as shall be issuable (taking into account the adjustments of
Section 5(d) hereof) upon the conversion of all outstanding shares of Preferred Stock. The Company covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly and validly authorized, issued and fully paid and nonassessable. The Company promptly will take such corporate action as may, in the opinion of its counsel, which may be an employee of the Company, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purpose, including without limitation engaging in best efforts to obtain the requisite stockholder approval.

(h) Fractional Shares. Upon a conversion hereunder the Company shall not be required to issue stock certificates representing fractions of shares of Common Stock, but may if otherwise permitted by applicable law make a cash payment in respect of any final fraction of a share based on the Per Share Market Value at such time. If the Company elects not, or is unable, to make such a cash payment, the Holder of a share of Preferred Stock shall be entitled to receive, in lieu of the final fraction of a share, one whole share of Common Stock.

(i) Taxes. The issuance of certificates for shares of Common Stock on conversion of Preferred Stock shall be made without charge to the Holders thereof for any documentary, stamp or similar taxes that may be payable in respect of the issue or delivery of such certificate, provided that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the Holder of such shares of Preferred Stock so converted and the Company shall not be required to issue or deliver such certificates unless or until the person or persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

(j) Status of Converted or Redeemed Shares. Shares of Preferred Stock converted into Common Stock or redeemed shall be canceled and shall have the status of authorized but unissued shares of Preferred Stock.

(k) Giving of Notice. Each Conversion Notice shall be given (i) by facsimile and by mail, postage prepaid, addressed to the attention of the Chief Financial Officer of the Company at the facsimile telephone number and address of the principal place of business of the Company, (ii) by overnight courier or
(iii) by hand. Any such notice shall be deemed given and effective upon the earliest to occur of (1)(a) if such Conversion Notice is delivered via facsimile prior to 4:30 p.m. (local time in New York, NY) on any date, such date or such later date as is specified in the Conversion Notice, and (b) if such Conversion Notice is delivered via facsimile after 4:30 p.m. (local time in New York, NY) on any date, the next date or such later date as is specified in the Conversion Notice, (2) if such Conversion Notice is delivered by overnight courier, two business days after delivery to a nationally recognized overnight courier service or (3) if such Conversion Notice is delivered by hand, upon actual receipt.

SECTION 6. Redemption. The Company may, at the option of the Board of Directors, redeem all or any part of the outstanding Preferred Stock at any time after the third anniversary of the Original Issue Date, by paying for each share so redeemed the redemption prices listed below, together with an amount equal to all cumulative dividends accrued and unpaid thereon to the date fixed for redemption, provided that notice of redemption is sent by certified mail to the Holders of the Preferred Stock to be redeemed at least 40 but not more than 60 days prior to the date of redemption specified in such notice, addressed to each such Holder at his/her address as it appears in the records of the Company. On or after the redemption date, each Holder of shares of Preferred Stock to be redeemed shall present and surrender his/her certificate or certificates for such shares to the Company at the place designated in such notice and thereupon the redemption price of such shares shall be paid to or to the order of the person whose name appears on such certificate or certificates as the owner thereon and each surrendered certificate shall be cancelled. In case less than all the shares represented by any such certificates are redeemed, a certificate shall be issued representing the unredeemed shares. From and after the redemption date (unless default shall be made by the Company in payment of the redemption price) all dividends on the shares of Preferred Stock designated for redemption in such notice shall cease to accrue, and all rights of the Holders thereof as stockholders of the Company, except the right to receive the redemption price thereof upon the surrender of certificates representing the same, without interest, shall cease and terminate and such shares shall not thereafter be transferred (except with the consent of the Company) on the books of the Company, and such shares shall

not be deemed to be outstanding for any purpose whatsoever. At its election, the Company prior to the redemption date may deposit the redemption price of the shares of Preferred Stock so called for redemption in trust for the Holders thereof with a bank or trust company (having a capital and surplus of not less than $500,000,000) in which case such notice to Holders of the Preferred Stock to be redeemed shall state the date of such deposit, shall specify the office of such bank or trust company as the place of payment of the redemption price, and shall call upon such Holders to surrender the certificates representing such shares at such price on or after the date fixed in such redemption notice (which shall not be later than the redemption date) against payment of the redemption price. From and after the making of such deposit, the shares of Preferred Stock so designated for redemption shall not be deemed to be outstanding for any purpose whatsoever, and the rights of the Holders of such shares shall be limited to the right to receive the redemption price of such shares, without interest, upon surrender of the certificates representing the same to the Company at said office of such bank and trust company, and the right of conversion (on or before the close of business on the last business day prior to the date fixed for redemption) herein provided. Any funds so deposited which shall not be required for such redemption because of the exercise of such right of conversion after the date of such deposit shall be returned to the Company. Any interest accrued on such funds shall be paid to the Company from time to time. Any moneys so deposited which shall remain unclaimed by the Holders of such Preferred Stock at the end of three years after the redemption date shall be returned by such bank or trust company to the Company after which the Holders of the Preferred Stock shall look only to the Company for payment of the redemption price. In the event that less than all the outstanding shares of Preferred Stock are to be redeemed at one time, the shares so to be redeemed shall be redeemed pro rata. The prices at which each share of Preferred Stock may be redeemed during the periods set forth below are as follows:

Prior to the third anniversary of the Original Issue Date: No right to redeem.

After the third anniversary of the    $52.00 together with an amount equal
Original Issue Date but before the    to all cumulative dividends accrued
fourth anniversary of the Original    and unpaid thereon to the date of
Issue Date:                           redemption.

After the fourth anniversary of the   $51.60 together with an amount equal
Original Issue Date but before the    to all cumulative dividends accrued
fifth anniversary of the Original     and unpaid thereon to the date of
Issue Date:                           redemption.

Original Issue Date but before the    to all cumulative dividends accrued
sixth anniversary of the Original     and unpaid thereon to the date of
Issue Date:                           redemption.

After the sixth anniversary of the    $50.80 together with an amount equal
Original Issue Date but before the    to all cumulative dividends accrued
seventh anniversary of the Original   and unpaid thereon to the date of
Issue Date:                           redemption.

After the seventh anniversary of      $50.40 together with an amount equal
the Original Issue Date but before    to all cumulative dividends accrued
the eighth anniversary of the         and unpaid thereon to the date of
Original Issue Date:                  redemption.

After the eighth anniversary of the   $50.00 together with an amount equal
Original Issue Date:                  to all cumulative dividends accrued
                                      and unpaid thereon to the date of
                                      redemption.

SECTION 7. Definitions. For the purposes hereof, the following terms shall have the following meanings:

"Purchase Agreement" means the Cumulative Convertible Preferred Stock Purchase Agreement, dated as of the Original Issue Date, between the Company and the original Holder of the Preferred Stock.

"Trading Day" means (a) a day on which the Common Stock is traded on The Nasdaq Stock Market or principal stock exchange on which the Common Stock is then listed. or (b) if the Common Stock is not listed on The Nasdaq Stock Market or any stock exchange, a day on which the Common Stock is traded in the over-the-counter market, as reported by the NASD, or (c) if the Common Stock is not quoted on The Nasdaq Stock Market, a day on which the Common Stock is quoted in the over-the-counter market as reported by the National Quotation Bureau Incorporated (or any similar organization or agency succeeding its functions of reporting prices).

Notice of each meeting, other than a regular meeting (unless required by the board of directors), shall be given to each director by mailing the same to each director at his residence or business address at least two days before the meeting or by delivering the same to him personally or by telephone or telegraph to him at least one day before the meeting unless, in case of exigency, the president or secretary shall prescribe a shorter notice to be given personally or by telephone, telegraph, telefax, cable or wireless to all or any one or more of the directors at their respective residences or places of business.

Notice of all meetings shall state the time and place of such meeting, but need not state the purposes thereof unless otherwise required by statute, the Certificate of Incorporation, the Bylaws, or the board of directors.

5. Executive committee. The board of directors may by resolution passed by a majority of the whole board provide for an executive committee of two or more directors and shall elect the members thereof to serve during the pleasure of the board and may designate one of such members to act as chairman. The board may at any time change the membership of the committee, fill vacancies in it, designate alternate members to replace any absent or disqualified members at any meeting of the committee, or dissolve it.

During the intervals between the meetings of the board of directors, the executive committee shall possess and may exercise any or all of the powers of the board of directors in the management of the business and affairs of the corporation to the extent authorized by resolution adopted by a majority of the entire board of directors, subject to such limitations as may be imposed by the laws of Delaware.

The executive committee may determine its rules of procedure and the notice to be given of its meetings, and it may appoint such committees and assistants as it shall from time to time deem necessary. A majority of the members of the committee shall constitute a quorum.

6. Other committees. The board of directors by resolution may provide for such other standing or special committees as it deems desirable and may discontinue the same at its pleasure.

At any annual meeting of stockholders, only persons who are nominated in accordance with the procedures set forth in the Bylaws shall be eligible to be elected at such meeting as directors. Nominations of persons for election to the board of directors may be made at a meeting of stockholders (a) by or at the direction of the board of directors or (b) by any stockholder who is a stockholder of record at the time of giving of notice provided for in this Section, who shall be entitled to vote for the election of directors at

the meeting and who complies with the notice procedures set forth in this Section. Such nominations, other than those made by or at the direction of the board of directors, shall be made pursuant to timely notice in writing to the Secretary. To be timely, a stockholder's notice shall be delivered to or mailed and received at the principal executive offices of the corporation not less than 45 days prior to the date on which the corporation first mailed its proxy materials for the prior year's annual meeting of stockholders. Such stockholder's notice shall set forth (a) as to each person whom the stockholder proposes to nominate for election or reelection as a director all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (including such person's written consent to being named in the proxy statement as a nominee and to serving as a director if elected); and (b) as to the stockholder giving the notice (i) the name and address, as they appear on the corporation's books, of such stockholder supporting such nomination and (ii) the class and number of shares which are beneficially owned by such stockholder. At the request of the board of directors, any person nominated to the board of directors for election as a director shall furnish to the Secretary that information required to be set forth in a stockholder's notice of nomination which pertains to the nominee. Except as otherwise provided in the Certificate of Incorporation or these Bylaws, no person shall be eligible to serve as a director unless nominated in accordance with the procedures set forth in this Bylaw. The chairman of the meeting shall, if the facts warrant, determine and declare to the meeting that a nomination was not made in accordance with the procedures prescribed in the Bylaws, and if he should so determine, he shall so declare to the meeting and the defective nomination shall be disregarded. Notwithstanding the foregoing provisions of this Section, a stockholder shall also comply with all applicable requirements of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder with respect to the matters set forth in this Section.

8. Chairman of the Board. The Chairman of the Board (hereinafter sometimes called the "Chairman") if appointed by the board of directors, when present shall preside at all meetings of the stockholders, the board of directors and the Executive Committee. The Chairman shall perform such other duties as the board of directors or Executive Committee may prescribe from time to time.

9. Action without meetings. Any action required or permitted to be taken at any meeting of the board of directors or any committee thereof may be taken without a meeting if all members of the board of directors or committee, as the case may be, consent thereto in writing and the writing is filed with the minutes of the proceedings of the board of directors or such committee.

The transfer books shall be closed for such a period as the board shall direct previous to and on the day of the annual or any special meeting of the stockholders and may also be closed by the board for such period as may be advisable for dividend purposes, and during such time no stock shall be transferable.

ARTICLE XII

INDEMNIFICATION OF DIRECTORS AND OFFICERS

(a) Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a "proceeding"), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as a director, officer, employee or agent, shall be indemnified and held harmless by the corporation to the fullest extent authorized by the Delaware General Corporation Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the corporation to provide broader indemnification rights than said law permitted the corporation to provide prior to such amendment) against all expense, liability and loss (including attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts to be paid in settlement) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators; provided, however, that except as provided in paragraph (b) hereof with respect to proceedings seeking to enforce rights to indemnification, the corporation shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the board of directors of the corporation. The right to indemnification conferred in this Section shall be a contract right and shall include the right to be paid by the corporation the expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, that, if the Delaware General Corporation Law requires, the payment of such expenses incurred by a director or officer in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of a proceeding, shall be made only upon delivery to the corporation of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under this Section or otherwise.

(b) Right of Claimant to Bring Suit. If a claim under paragraph (a) of this Section is not paid in full by the corporation within 60 days after a written claim has been received by the corporation, except in the case of a claim for expenses incurred in defending a proceeding in advance of its final disposition, in which case the applicable period shall be 20 days, 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 be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been

tendered to the corporation) that the claimant has not met the standards of conduct which make it permissible under the Delaware General Corporation Law for the corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the corporation.

(c) Non-Exclusivity of Rights. The right to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Section shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, Bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

(d) Insurance. The corporation may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the corporation, or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the corporation would have the power to indemnify such person against such expense, liability or loss under the Delaware General Corporation Law.

(e) Amendment or Repeal. Any repeal or modification of the foregoing provisions of this Article XII shall not adversely affect any right of a director, officer, employee or agent of the corporation in respect of any act or omission occurring prior to the time of such repeal or modification.

ARTICLE XIII

AMENDMENTS

Subject to the provisions of the Certificate of Incorporation, the Bylaws may be altered, amended or repealed either by the affirmative vote of a majority of the board of directors at any regular or special meeting of the board of directors, or by the affirmative vote of the holders of record of at least 66-2/3% of the voting power of the outstanding shares of capital stock of the corporation entitled to vote at an annual meeting or at any special meeting at which a quorum shall be present, provided that in each case notice of the proposed change was given in the notice of the meeting of the board or the stockholders, or the form of consent thereof, as the case may be.
