(iii) Conversion. ---------- (A) Class A Common Stock and Class B Common Stock. Each --------------------------------------------- record holder of Class A Common Stock will be entitled to convert any or all of such holder's Class A Common Stock into the same number of shares of Class B Common Stock (but only to the extent that such record holder of Class A Common Stock shall be deemed to be required to convert such Class A Common Stock into Class B Common Stock pursuant to applicable law), and each record holder of Class B Common Stock will be entitled to convert any or all of the shares of such holder's Class B Common Stock into the same number of shares of Class A Common Stock; provided, however, that at the time of conversion of shares of -------- ------- Class B Common Stock into shares of Class A Common Stock such holder would be permitted, pursuant to applicable law, to hold the total number of shares of Class A Common Stock which he would hold after giving effect to such conversion. Each conversion of shares of Class A Common Stock into shares of Class B Common Stock, or shares of Class B Common Stock into shares of Class A Common Stock, as the case may be, will be effected by the surrender of the certificate or certificates representing the shares to be converted at the principal office of the Corporation at any time during normal business hours, together with a written notice by the holder of such shares stating the number of shares that any such holder desires to convert into the other class of Common Stock. Such conversion will be deemed to have been effected as of the close of business on the date on which such certificate or certificates have been surrendered and such notice has been received by the Corporation, and at such time the rights of such holder with respect to the converted class of Common Stock will cease and the person or persons in whose name or names the certificate or certificates for shares of the other class of Common Stock are to be issued upon such conversion will be deemed to have become the holder or holders of record of the shares of such other class of Common Stock represented thereby. Promptly after such surrender and the receipt by the Corporation of the written notice from the holder hereinbefore referred to, the Corporation will issue and deliver in accordance with the surrendering holder's instructions the certificate or certificates for the other class of Common -4- Stock issuable upon such conversion and a certificate representing any shares of Common Stock which were represented by the certificate or certificates delivered to the Corporation in connection with such conversion but which were not converted. The issuance of certificates for the other class of Common Stock upon conversion will be made without charge to the holder or holders of such shares for any issuance tax (except stock transfer taxes) in respect thereof or other cost incurred by the Corporation in connection with such conversion. (B) Class C Common Stock. A share of Class C Common Stock -------------------- will automatically be converted into a share of Class A Common Stock (i) immediately prior to its sale in a Subsequent Public Offering; or (ii) at such time as such share of Class C Common Stock has been sold in a Public Sale after a Subsequent Public Offering, and in compliance with the maximum quantity limitations as set forth in paragraph 4(a)(iv)(C) hereof, if such maximum quantity limitations remain in effect. On the date of such automatic conversion, all rights with respect to the Class C Common Stock so converted will terminate, except for the rights of the holders thereof, upon surrender of their certificate or certificates therefor, to receive certificates for an equal number of shares of Class A Common Stock. As soon as practical after the date of such automatic conversion, the holder of shares of Class C Common Stock so converted shall surrender to the Corporation the certificate or certificates representing the shares so converted, and thereafter the Corporation shall cause to be issued and delivered to such holder a certificate for the number of shares of Class A Common Stock issuable upon such conversion in accordance with the provisions hereof. All certificates evidencing shares of Class C Common Stock which are automatically converted into Class A Common Stock in accordance with the provisions hereof shall, from and after the dates such certificates are so converted, be deemed to have been retired and cancelled and the shares of Class C Common Stock represented thereby converted into Class A Common Stock for all purposes, notwithstanding the failure of the holder or holders thereof to surrender such certificates to the Corporation. The Corporation may thereafter take such appropriate action as may be necessary to reduce the authorized shares of Class C Common Stock accordingly. Upon such automatic conversion of a share of Class C Common Stock into a share of Class A Common Stock, such share will no longer be subject to any of the restrictions on transfer described herein. -5- (iv) Restrictions on Transfer. ------------------------ (A) Restrictions Prior to Transfer Restriction Termination ------------------------------------------------------ Date and During Holdback Period. Except as provided in paragraph 4(a)(iv)(B) - ------------------------------- hereof, prior to and on the Transfer Restriction Termination Date, and during any Holdback Period, a holder of shares of Class C Common Stock may not effect a Transfer of such shares, unless (1) the transferee is an Accredited Investor, (2) the Transfer under consideration is a privately negotiated transaction and (3) the number of shares of Class C Common Stock subject to the transfer is not less than the lesser of (i) 2,500 shares or (ii) all shares of Class C Common Stock held by such holder. The minimum number of shares set forth in the previous sentence shall be appropriately adjusted in the event of a stock split, reverse stock split, stock dividend or similar transaction by the Corporation. (B) Certain Exceptions. A Transfer of shares of Class C -------------------- Common Stock may be effected without regard to the provisions of paragraph 4(a) (iv)(A) hereof under the following circumstances: (1) If the holder of shares of Class C Common Stock is a natural person, pursuant to will or the laws of descent and distribution; (2) If the holder of shares of Class C Common Stock is not a natural person, pursuant to a merger of such holder into, consolidation of such holder with, or sale of all or substantially all of the assets of such holder to, another entity; (3) If the holder of shares of Class C Common Stock is not a natural person, pursuant to the liquidation or dissolution (voluntary or involuntary) or winding up of such holder; or (4) In order to enable the holder to exchange or transfer shares of Class C Common Stock in connection with a merger of the Corporation into, or the consolidation of the Corporation with, a corporation (other than a subsidiary of the Corporation) where such other corporation survives the merger. (C) Restrictions After Transfer Restriction Termination --------------------------------------------------- Date. Except during a Holdback Period, after the Transfer Restriction Date, - ---- a holder of shares of Class C Common Stock may transfer such shares free of any restrictions on transfer contained herein; provided, that for a -------- -6- period of 270 days after the Transfer Restriction Termination Date, the number of shares of Class C Common Stock sold publicly in brokers' transactions (within the meaning of Section 4(4) of the Securities Act) by such holder and its affiliates, together with the number of shares of Common Stock sold publicly in such brokers' transactions by such holder and its affiliates within the preceding three months, shall not exceed the greater of (i) one percent of the shares of Common Stock outstanding as shown by the most recent report or statement published by the Corporation, or (ii) the average weekly reported volume of trading in Common Stock on all national securities exchanges and/or reported through the automated quotation system of a registered securities association during the four calendar weeks preceding the date of such transfer. The calculation of the number of shares set forth in the preceding sentence shall be made as if a paragraph (e)(3)(i) through paragraph (e)(3)(v) of Rule 144 under the Securities Act (as in effect on September 14, 1989) were applicable. (D) Effect of Restrictions; Legends. ------------------------------- (1) Any purported Transfer in violation of the terms set forth herein shall be null and void and of no force and effect, and the purported transferee shall have no rights or privileges in or with respect to the Corporation. Before the Corporation registers a Transfer of Class C Common Stock on its stock record books, it may require proof, satisfactory to the Corporation, that the Transfer complies with the restrictions on Transfer contained herein. The Corporation shall, in its sole discretion, be entitled to resolve any and all disputes relating to compliance with the restrictions on Transfer set forth herein, including, but not limited to, the conversion of shares of Class C Common Stock into shares of Class A Common Stock under paragraph (4)(a)(iii)(B) hereof. (2) Certificates representing shares of Class C Common Stock will bear a legend indicating that such shares are subject to the restrictions on transfer set forth herein. (v) Transfers. The Corporation will not close its books against --------- the transfer of any share of Common Stock, or of any share of Common Stock issued or issuable upon conversion of shares of the other Class of Common Stock, in any manner that would interfere with the timely conversion of such shares of Common Stock. -7- (vi) Subdivision and Combinations of Shares. If the Corporation -------------------------------------- in any manner subdivides or combines the outstanding shares of any class of Common Stock, the outstanding shares of the other classes of Common Stock will be proportionately subdivided or combined.
