Section 2.3.           Right of First Refusal.

(a)                                  Effective as of the first anniversary of the date of the Agreement and thereafter through the remainder of the term of this Agreement, each Stockholder (the “Transferring Stockholder”) desiring to Transfer any of the Securities owned by the Transferring Stockholder shall give the Company and each other Stockholder (each, an “Other Stockholder”) notice of the terms of any proposed bona fide sale of Offered Securities, including (i) the number and type of Securities that are proposed to be Transferred, (ii) the anticipated date of the proposed Transfer, (iii) the name and address of each Person to whom the Transfer is proposed to be made and (iv) the material terms of the proposed Transfer, including the cash and/or other consideration to be received with respect to such Transfer, at least 30 days prior to the consummation of such proposed Transfer (a “Transfer Notice”); provided, however, that in connection with a Transfer pursuant to a Public Sale, the Transferring Stockholder shall deliver the Transfer Notice to the Company and each Other Stockholder at least ten business days, or any other time period as may be mutually agreed upon by the parties to this Agreement, prior to the consummation of such proposed Transfer pursuant to a Public Sale.  Any such Transfer Notice shall be deemed an irrevocable bona fide offer to sell such shares to the Company, initially, and, thereafter, the Other Stockholders, on such terms as set forth in such Transfer Notice and shall be deemed a representation by the Transferring Stockholder that the proposed Transfer is a bone fide transaction.

4

(b)                                 The Company shall have a period of (i) five business days, in connection with a Transfer pursuant to a Public Sale, or (ii) fifteen business days, in connection with any other Transfer, from the giving of the Transfer Notice with respect to such Transfer within which to elect to purchase all or any portion of the Offered Securities at the same price and subject to the same material terms and conditions as described in the Transfer Notice.  The Company may exercise such purchase option, and thereby purchase all or any portion of the Offered Securities, by notifying the Transferring Stockholder in writing, before the expiration of such five or fifteen business day period, as the case may be, as to the number and kind of such Securities that the Company wishes to purchase.  If the Company gives the Transferring Stockholder notice that the Company desires to purchase all or a portion of the Offered Securities, then payment for the Offered Securities shall be in cash, by check or wire transfer or in such other consideration as set forth in the Transfer Notice, against delivery of the Offered Securities to be purchased at a place, at a time and on a date agreed upon by the Transferring Stockholder and the Company, or, if the parties are unable to agree on the place, time and date of such purchase and sale, at 10:00 am (local time) on the 25th business day after the expiration of such five or fifteen business day period at the principal offices of the Company.  Neither the Transferring Stockholder nor any member of the Board of Directors elected by holders of a class of securities of the Company in which the Transferring Stockholder owns of record or beneficially a majority of the outstanding shares of such class of securities may participate in the determination by the Company whether of not to purchase the Offered Securities pursuant to this paragraph 2(b).

(c)                                  If the Company shall have failed to elect to purchase all of the Offered Securities by giving the Transferring Stockholder the notice contemplated by paragraph 2.3(b), the Other Stockholders shall have a period of (i) ten business days, in connection with a Transfer pursuant to a Public Sale, and (ii) 25 business days, in connection with any other Transfer, from the giving of the Transfer Notice with respect to such Transfer within which to elect to purchase their respective pro rata shares of the Offered Securities not being purchased by the Company, at the same price and subject to the same material terms and conditions as described in the Transfer Notice.  Each Other Stockholder may exercise such purchase option, and thereby purchase all or any portion of its pro rata share of the Offered Securities not being purchased by the Company, by notifying the Transferring Stockholder in writing, before the expiration of such ten or 25 business day period, as the case may be, as to the number of such shares that the Other Stockholder desires to purchase.  For the purpose of the preceding sentence, each Other Stockholder’s pro rata share shall be a fraction of the Offered Securities not being purchased by the Company, the numerator of which shall be the number of shares of Common Stock issuable upon conversion of Class A Common Stock and Class B Common Stock upon the occurrence of a Threshold Event (as such term is defined in the Certificate of Incorporation of the Company) and the number of shares of Common Stock owned by such Other Stockholder on the date of the Transfer

5

Notice and the denominator of which shall be the total number of shares of Common Stock then outstanding plus the number of shares of Common Stock issuable upon conversion of Class A Common Stock and Class B Common Stock upon the occurrence of a Threshold Event then owned by all Other Stockholders, each as of the date of the Transfer Notice.  Each participating Other Stockholder shall have a right of reallotment such that, if any Other Stockholder fails to exercise the right to purchase such other Stockholder’s full pro rata share of the Offered Securities, each participating Other Stockholders may exercise an additional right to purchase, on a pro rata basis, the Offered Securities not previously purchased.  If a participating Other Stockholder gives the Transferring Stockholder notice that the participating Other Stockholder desires to purchase its pro rata share of the Offered Securities and, as the case may be, its reallotment, then payment for the Offered Securities shall be in cash, by check or wire transfer or in such other consideration as set forth in the Transfer Notice, against delivery of the Offered Securities to be purchased at a place, at a time and on a date agreed upon by the Transferring Stockholder and the Company, or, if the parties are unable to agree on the place, time and date of such purchase and sale, at 10:00 am (local time) on the fifth business day after the expiration of such ten or 25 business day period at the principal offices of the Company.

(d)                                 If all the Offered Securities are not so purchased by the Company and Other Stockholders, the Transferring Stockholder shall be free for a period of 90 days after expiration of the time periods referred to in this Section 2.3 to consummate the proposed transaction upon terms not more favorable to the Transferring Stockholder than those set forth in the Transfer Notice with respect to any Offered Securities not sold to the Company and the Other Stockholders pursuant to this Section 2.3.  Promptly upon the consummation of any such transaction, the Transferring Stockholder shall confirm in writing to the Company and Other Stockholders the terms of the transaction as so consummated, including the number and kind of Securities involved, the consideration received, and the name of the party to whom the Transfer was made. After the expiration of said 90 day sale period, subject to the time period set forth in paragraph 2.3(a), if such Transferring Stockholder again wishes to Transfer any Securities, such Transferring Stockholder shall again offer the Securities in accordance with the provisions of this Section 2.3.

(e)                                  Should the purchase price specified in the Transfer Notice be payable in property other than cash or evidences of indebtedness, the Company and Other Stockholders shall have the right to pay the purchase price in the form of cash equal in amount to the value of such property.  If the Transferring Stockholder and the Company and such Other Stockholders cannot agree on such cash value within fifteen business days after the receipt of the Transfer Notice, the valuation shall be made by an appraiser of recognized standing selected by the Company.  The cost of such appraisal shall be shared equally by the Company, such Other Stockholders and the Transferring Stockholder.

Section 2.4.           Drag Along Rights.

(a)                                  Effective as of the first anniversary of the date of this Agreement and thereafter through the remainder of the term of this Agreement, in the event the holders of a majority of the then outstanding shares of Class A Common Stock or Class B Common Stock (and, following the occurrence of a Threshold Event, the Common Stock) (in either case, the “Control Group”) elect to transfer all of the Securities owned by the members of the Control Group to an unaffiliated third party (a “Third Party”) (including any transfer of shares that is being effected by a merger or consolidation of the Company with another person), the Control Group shall have the right (the “Drag-Along Right”) to cause each of the other Stockholders as a group to transfer all of their Securities to the Third Party (or to exchange such Securities pursuant to the terms of such merger or consolidation) at the same price and on the same terms and conditions as the Control Group Transfer their Securities to the Third Party; provided, however, that, in connection with the exercise of a Drag-Along Right prior to the occurrence of a Threshold Event, the holders of Class B Common Stock shall be entitled to receive, in aggregate, no less than 10% of the total consideration being tendered by the Third Party in connection with such transaction.

(b)                                 The Control Group may elect to exercise the Drag-Along Right by delivering written notice to all of the other Stockholders and the Company 30 days prior to the consummation of the Transfer described in paragraph 2.4(a), such notice to be accompanied by a copy of the definitive documentation pursuant to which the Securities will be transferred to the Third Party by the Control Group and will state (i) the bona fide intention of the Control Group to effect the Transfer described in paragraph 2.4(a), (ii) the name and address of the Third Party and (iii) the expected closing date of such Transfer.  The notice delivered pursuant to this paragraph 2.4(b) shall also be deemed a Transfer Notice under paragraph 2.3(a) and the Company and all other Stockholders shall have all of the rights granted under Section 2.3 with respect to the Securities owned by the Control Group.

(c)                                  Each Stockholder as part of its participation in the Transfer pursuant to a duly exercised Drag-Along Right shall deliver to the Third Party at a closing to be held at the offices of the Company (or such other place as the parties agree), one or more certificates, properly endorsed for transfer, which represent all of the Securities owned by such Stockholder and each Stockholder shall make such representations and warranties, and shall enter into such agreements, as are customary and reasonable in the context of the proposed sale, including, without limitation, representations and warranties (and indemnities with respect thereto) that the transferee of the Securities (or interests therein) is receiving good and marketable title to such Securities (or interests therein), free and clear of all pledges, security interests, or other liens; provided, however, that with respect to any matter as to which a Stockholder shall agree to provide indemnification (other

7

than its own title to such Securities), such Stockholder shall in no event be required to provide indemnification in an amount that would exceed its pro rata portion of the total liability for which such indemnification is sought, which pro rata portion shall be determined on the basis of the percentage of the total Securities involved in such transfer that are represented by the Securities owned by such Stockholder.  In addition, each Stockholder and the Control Group shall reasonably cooperate and consult with each other in order to effect the Transfer described in this Section 2.4, and each Stockholder shall provide reasonable assistance to the Control Group in connection with the preparation of disclosure schedules relating to representations and warranties to be made to the Third Party in connection with such Transfer and in the determination of the appropriate scope of, or limitations or exceptions to, such representations and warranties.

(e)                                  In the event that the Control Group consists of holders of a majority of the then outstanding shares of Class A Common Stock and such Control Group desires to Transfer less than all of the shares of Class A Common Stock owned by the members of such Control Group, all of the provisions of this Section 2.4 shall remain applicable proportionately (as the number of shares of Class A Common Stock owned by the Control Group subject to the partial exercise of the Drag-Along Right bears to the total number of shares of Class A Common Stock owned by the Control Group), but only with respect to Class A Common Stock and shall only be effective if the Third Party becomes a party to this Agreement as an Investor Stockholder by executing and delivering to the Company a duly completed, dated and executed Instrument of Accession.

8

(b)                                 In the event a Substitute Purchase Offer is made, the Purchase Offer Stockholder Recipient shall give each of the other Stockholders written notice of the making of the Substitute Purchase Offer (the “Substitute Purchase Offer Notice”) specifying (i) the number and kind of Securities that is the subject of such Substitute Purchase Offer, (ii) the terms (including the proposed date of consummation of the Substitute Purchase Offer, which shall be not less than 30 business days following the date of the giving of the Substitute Purchase Offer Notice) of such Substitute Purchase Offer, and (iii) the identity of the proposed purchaser.  Upon receipt of the Substitute Purchase Offer Notice, each Stockholder shall have the right (the “Tag-Along Rights”) to participate in the Substitute Purchase Offer, pro rata, with the Purchase Offer Stockholder Recipient.
