Each share of Class A Common Stock shall --------------------- be convertible, at the option of its record holder, into one validly issued fully paid and non-assessable share of Common Stock at any time. (b) Voluntary Conversion Procedure. At the time of a voluntary ------------------------------- conversion, the record holder of shares of Class A Common Stock shall deliver to the principal office of the Corporation or any transfer agent for shares of Common Stock (i) the certificate or certificates representing the shares of Class A Common Stock to be converted, duly endorsed in blank or accompanied by proper instruments of transfer and (ii) written notice to the Corporation stating that the 6 record holder elects to convert such share or shares and stating the name or names (with addresses) and denominations in which the certificate or certificates representing the shares of Common Stock issuable upon the conversion are to be issued and including instructions for the delivery thereof.

Upon such delivery, the Corporation or its transfer agent shall promptly issue and deliver at the stated address of such record holder of shares of Common Stock a certificate or certificates representing the number of shares of Common Stock to which such record holder is entitled by reason of such conversion, and shall cause such shares of Common Stock to be registered in the name of the record holder.

(ii) Each share of Class A Common Stock shall automatically convert into one share of Common Stock on the first date on which the Ownership Interest of the TDF Group is less than 5%.

Any conversion pursuant to an ------------------------------- Event of Automatic Conversion shall be deemed to have been effected at the time the Event of Automatic Conversion occurred (the "Conversion Time"). At the Conversion Time, the certificate or certificates that represented immediately prior thereto the shares of Class A Common Stock which were so converted (the "Converted Class A Common Stock") shall, automatically and without further action, represent the same number of shares of Common Stock. Holders of Converted Class A Common Stock shall deliver their certificates, duly endorsed in blank or accompanied by proper instruments of transfer, to the principal office of the Corporation or the office of any transfer agent for shares of the Common Stock, together with a notice setting out the name or names (with addresses) and denominations in which the certificate or certificates representing such shares of Common Stock are to be issued and including instructions for delivery thereof. Upon such delivery, the Corporation or its transfer agent shall promptly issue and deliver at such stated address to such holder of shares of Common Stock a certificate or certificates representing the number of shares of Common Stock to which such holder is entitled by reason of such conversion. The Person entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder of such shares of Common Stock at and as of the Conversion Time, and the rights of such Person as a holder of shares of Class A Common Stock that have been converted shall cease and terminate at and as of the Conversion Time, in each case without regard to any failure by such holder to deliver the certificates or the notice required by this Section. 8 (e) Unconverted Shares; Notice Required. In the event of the ------------------------------------ conversion of less than all the shares of Class A Common Stock evidenced by a certificate surrendered to the Corporation in accordance with the procedures of this Section C.4, the Corporation shall execute and deliver to or upon the written order of the holder of such unconverted shares, without charge to such holder, a new certificate evidencing the number of shares of Class A Common Stock not converted. (f) Retired Shares. Shares of Class A Common Stock that are --------------- converted into shares of Common Stock as provided herein shall not be re- issued as shares of Class A Common Stock and shall be retired and canceled.

All the shares of Common Stock so issuable shall, when so issued, be duly and validly issued, fully paid and non-assessable, and free from liens and charges with respect to such issuance. (h) Determination of Voting Rights and Events of Automatic ------------------------------------------------------ Conversion. The Board of Directors of the Corporation shall have the power ----------- to determine by a two-thirds vote of the entire Board of Directors, in good faith after reasonable inquiry, whether an Event of Automatic Conversion has occurred with respect to any share of Class A Common Stock.

ARTICLE VII Board of Directors ------------------ Subject to the rights of the holders of any series of Preferred Stock to elect additional Directors under specified circumstances, the number of Directors of the Corporation shall initially be 12 (including the two Directors to be elected by the holders of the Class A Common Stock) and may hereafter be changed from time to time solely by the Board of Directors. Unless and except to the extent that the By-laws of the Corporation shall so require, the election of Directors of the Corporation need not be by written ballot. The Directors, other than those Directors who may be elected by the holders of any series of Preferred Stock or holders of Class A Common Stock (the "Non-Classified Directors"), shall be divided into three classes, as nearly equal in number as possible, initially consisting of 3, 3 and 4 Directors. One class of Directors initially consisting of 3 Directors shall be initially elected for a term expiring at the annual meeting of stockholders to be 13 held in 1999, another class initially consisting of 3 Directors shall be initially elected for a term expiring at the annual meeting of stockholders to be held in 2000, and another class initially consisting of 4 Directors shall be initially elected for a term expiring at the annual meeting of stockholders to be held in 2001.

The Corporation may, by action of the Board of Directors, provide indemnification to other employees and agents of the Corporation, to directors, officers, employees or agents of a subsidiary, and to each person serving as a director, officer, partner, member, employee or agent of another corporation, partnership, limited liability company, joint venture, trust or other enterprise, at the request of the Corporation, with the same scope and effect as the foregoing indemnification of Directors and officers of the Corporation. Notwithstanding the foregoing, the Corporation shall be required to indemnify any 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 or is a proceeding to enforce such person's claim to indemnification pursuant to the rights granted by this Restated Certificate of Incorporation or otherwise by the Corporation. Without limiting the generality of the effect of the foregoing, the Corporation may enter into one or more agreements with any person which provide for indemnification greater or different than that provided in this Article VIII. Any amendment or repeal of this Article VIII shall not adversely affect any right or protection existing hereunder in respect of any act or omission occurring prior to such amendment or repeal.

ARTICLE X Stockholder Rights Issuances ---------------------------- The Board of Directors is hereby authorized to create and issue, whether or not in connection with the issuance and sale of any of its stock or other securities or property, rights entitling the holders of securities of the Corporation to purchase from the Corporation shares of stock or other securities of the Corporation or any other corporation, recognizing that, under certain circumstances, the creation and issuance of such rights could have the effect of discouraging third parties from seeking, or impairing their ability to seek, to acquire a significant portion of the outstanding securities of the Corporation, to engage in any transaction which might result in a change of control of the Corporation or to enter into any agreement, arrangement or understanding with another party to accomplish the foregoing or for the purpose of acquiring, holding, voting or disposing of any securities of the Corporation. The times at which and the terms upon which such rights are to be issued will be determined by the Board of Directors and set forth in the contracts or instruments that evidence such rights. The authority of the Board of Directors with respect to such rights shall include, but not be limited to, determination of the following: (A) The initial purchase price per share or other unit of the stock or other securities or property to be purchased upon exercise of such rights.

(D) Provisions which deny the holder of the specified percentage of the outstanding stock or other securities of the Corporation the right to exercise such rights and/or cause the rights held by such holder to become void. (E) Provisions which permit the Corporation to redeem or exchange such rights, which redemption or exchange may be within the sole discretion of the Board of Directors, if the Board of Directors reserves such right to itself. (F) The appointment of the rights agent with respect to such rights. Notwithstanding anything contained in this Restated Certificate of Incorporation to the contrary, in addition to any other vote required by applicable law, the affirmative vote of at least 80 percent of the voting power of the then outstanding Voting Stock, voting together as a single class, shall be required to amend, repeal or adopt any provision inconsistent with this Article X. ARTICLE XI Other Agreements ---------------- Notwithstanding any other provision of this Restated Certificate of Incorporation, to the extent any provision of the Stockholders Agreement (attached as Exhibit B) or the Governance Agreement (attached as Exhibit A), conflict with, modify or alter any provision of this Restated Certificate of Incorporation, such provision of the Stockholders Agreement or of the Governance Agreement 17 shall control and be deemed incorporated as part of this Restated Certificate of Incorporation. ARTICLE XII Amendments ---------- Except as may be expressly provided in this Restated Certificate of Incorporation, the Corporation reserves the right at any time and from time to time to amend, alter, change or repeal any provision contained in this Restated Certificate of Incorporation or a Preferred Stock Designation, and any other provisions authorized by the laws of the State of Delaware at the time in force may be added or inserted, in the manner now or hereafter prescribed herein or by applicable law, and all rights, preferences and privileges of whatsoever nature conferred upon stockholders, Directors or any other persons whomsoever by and pursuant to this Restated Certificate of Incorporation in its present form or as hereafter amended are granted subject to the right reserved in this Article XII; provided, however, that any amendment or repeal of Article VIII or Article IX of - -------- ------- this Restated Certificate of Incorporation shall not adversely affect any right or protection existing thereunder in respect of any act or omission occurring prior to such amendment, alteration, change or repeal, and provided further that no Preferred Stock Designation shall be amended after the issuance of any shares of the series of Preferred Stock created thereby, except in accordance with the terms of such Preferred Stock Designation and the requirements of applicable law. Notwithstanding anything contained in this Restated Certificate of Incorporation to the contrary, and in addition to approval by the Board of Directors and any other vote of stockholders required by applicable law, the affirmative vote of the holders of at least 80% of the voting power of the then outstanding Voting Stock, voting together as a single class, shall be required to amend, repeal or adopt any provision inconsistent with paragraph (1) of Article V, Article VI, Article VII, Article X, Article XI or this second paragraph of this Article XII; provided, however, that, in addition to approval -------- ------- by the Board of Directors and any other vote of stockholders required by applicable law, any such amendment to Article XI or the provisions of this second paragraph of this Article XII with respect to such Article XI shall, in addition, require the approval of a majority of the holders the Class A Common Stock then outstanding, voting as a separate class. For the purposes of this Restated 18 Certificate of Incorporation, "Voting Stock" shall mean the outstanding shares of capital stock of the Corporation entitled to vote in a general vote of stockholders of the Corporation as a single class with shares of Common Stock of the Corporation, which shares of capital stock shall be deemed to include the Class A Common Stock.
