2. Restrictions on Transfer of Stockholder Shares.

(a) Transfer of Stockholder Shares. No Minority Stockholder shall sell, transfer, assign, pledge or otherwise dispose of (whether with or without consideration and whether voluntarily or involuntarily or by operation of law) (a “Transfer”) any interest in such Minority Stockholder’s Stockholder Shares without the prior written consent of the Company, except pursuant to (A) the provisions of Section 2(c) or 2(d) below, (B) a Public Sale, (C) an Employee Repurchase Event, (D) an Approved Sale (each of (A), (B), (C) and (D) an “Exempt Transfer”), or (E) the provisions of Section 2(b) below.

(b) First Refusal Rights.

(i) In the event that a Minority Stockholder proposes to Transfer any Stockholder Shares (except pursuant to an Exempt Transfer), such Minority Stockholder (a “Selling Minority Stockholder”) shall deliver written notice (an “Offer Notice”) to the Company and to CHS. The Offer Notice will disclose in reasonable detail the identity of the prospective transferee(s), the number and class of such Stockholder Shares to be transferred, and the terms and conditions of the proposed Transfer. The Selling Minority Stockholder shall not consummate any Transfer until 35 days after the Offer Notice has been given to the Company and CHS, unless the parties to the Transfer have been finally determined pursuant to this Section 2(b) before the expiration of such 35-day period. The date of the first to occur of such events is referred to herein as the “Authorization Date.”

(ii) The Company may elect to purchase all (but not less than all) of such Stockholder Shares as specified in the Offer Notice at the price and on the

terms specified therein by delivering written notice of such election to the Selling Minority Stockholder and to CHS as soon as practical but in any event within 15 days after the delivery of the Offer Notice. If the Company has not elected to purchase all of the Stockholder Shares within such 15-day period, CHS may elect to purchase all (but not less than all) of the Stockholder Shares specified in the Offer Notice at the price and on the terms specified therein by delivering written notice of such election to the Selling Minority Stockholder as soon as practical but in any event within 30 days after delivery of the Offer Notice (the “Election Period”). If, pursuant to this Section 2(b), the Company or CHS has elected to purchase all of the Stockholder Shares specified in the Offer Notice from the Selling Minority Stockholder, the Transfer will be consummated in accordance with the terms of the Offer Notice as soon as practicable after the delivery of the election notice, but in any event within 30 days after the expiration of the Election Period. If, pursuant to this Section 2(b), one of the Company or CHS has not elected to purchase all of the Stockholder Shares being offered, the Selling Minority Stockholder may, within 60 days after the expiration of the Election Period, transfer all (but not less than all) of such Stockholder Shares to the third party(ies) identified in the Offer Notice at a price no less than the price per Stockholder Share specified in the Offer Notice and on other terms no more favorable to the transferee(s) than the terms specified in the Offer Notice. Any Stockholder Shares not transferred within the 60-day period after the Election Period shall be reoffered to the Company and CHS pursuant to this Section 2(b) before any subsequent Transfer. The purchase price specified in any Offer Notice shall be payable solely in cash at the closing of the transaction or in installments over time.

(c) Minority Participation Rights. At least 30 days before a Transfer (other than an Exempt Transfer) by CHS or its Affiliates of any Stockholder Shares, CHS will deliver a written notice (the “Sale Notice”) to the Company and to each of the Minority Stockholders, specifying in reasonable detail the identity of the prospective transferee(s), the identity, number, and class or classes of Stockholder Shares to be transferred by CHS or its Affiliates, an estimate of each Minority Stockholder’s pro rata share of transaction expenses and the terms and conditions of the proposed Transfer. In the event that any Minority Stockholders holds the class of Stockholder Shares which are to be transferred, or securities exercisable, convertible or exchangeable for the class of Stockholder Shares which are to be transferred, such Minority Stockholder may elect to participate in the contemplated Transfer by delivering written notice to CHS within 15 days after delivery of the Sale Notice. If any such Minority Stockholder has elected to participate in such Transfer (each a “Participating Minority Stockholder”), then CHS or its Affiliates and each Participating Minority Stockholder will be entitled to transfer in the contemplated Transfer, at the same price and on the same terms specified in the Sale Notice, a number of Stockholder Shares of such class, or securities exercisable, convertible or exchangeable for Stockholder Shares of such class, equal to the number of Stockholder Shares of such class and securities convertible or exchangeable for Stockholder Shares of such class to be transferred in the contemplated Transfer multiplied by a fraction, the numerator of which is (A) the number of Stockholder Shares of such class and securities convertible or exchangeable for

Stockholder Shares of such class held by such Person on an as-if converted or exchanged basis, and the denominator of which is (B) the aggregate number of Stockholder Shares of such class and securities convertible or exchangeable for Stockholder Shares of such class held by CHS or its Affiliates and all Participating Minority Stockholders on an as-if converted or exchanged basis. CHS shall use its best efforts to obtain the agreement of the prospective transferee(s) to the participation of the Participating Minority Stockholders in any contemplated Transfer, and CHS or its Affiliates shall not Transfer any Stockholder Shares to the prospective transferee(s) unless (A) the prospective transferee(s) agrees to allow the participation of the Participating Minority Stockholders at the same price and on the same terms as specified in the Sale Notice, or (B) CHS agrees to purchase the number of Stockholder Shares that any Participating Minority Stockholder would have been entitled to Transfer pursuant to this Section 2(c) at the same price and on the same terms as specified in the Sale Notice. If, within 15 days after the delivery of the Sale Notice, no Minority Stockholder delivers to CHS written notice of its election to participate in the contemplated Transfer, then CHS or its Affiliates will be entitled to Transfer to the prospective transferee(s) specified in the Sale Notice the number of Stockholder Shares specified in the Sale Notice on the terms and conditions specified therein. Notwithstanding anything in this Section 2(c) to the contrary, if CHS or its Affiliates intends to simultaneously Transfer a combination of more than one class of Stockholder Shares and/or other debt or equity securities, and any Minority Stockholder holds or has the right to acquire both such classes of Stockholder Shares and/or other debt or equity securities, such Minority Stockholder may only participate in such Transfer if such Minority Stockholder Transfers all such classes of Stockholder Shares and/or other debt or equity securities in accordance with the formulae set forth in this Section 2(c) above.

(d) Permitted Transfers. Notwithstanding anything to the contrary in any other provision of this Agreement, the restrictions contained in this Sections 2 shall not apply to:

(i) any Transfer of Stockholder Shares by any Stockholder to or among any of its Affiliates;

(ii) a Transfer of Stockholder Shares by any Stockholder pursuant to the laws of descent and distribution or to or among such Stockholder’s Family Group; or

(iii) in the case of CHS, a Transfer of up to 5% in the aggregate of any class of Stockholder Shares held by CHS as of the date hereof to employees of, consultants to, and advisors to CHS, the Company, or any of their Affiliates.

3. Preemptive Right.

(a) If the Company authorizes the issuance or sale of any New Securities, the Company shall offer to sell to each holder of Common Stock and/or Rollover Common Options (a “Preemptive Holder”) a portion of such stock or securities equal to the quotient determined by dividing (1) the number of shares of Common Stock held by such holder at such time plus the number of shares of Common Stock issuable to such holder upon exercise of the Rollover

Common Options at such time by (2) the total number of shares of Common Stock then issued and outstanding plus the total number of shares of Common Stock issuable upon exercise of all then outstanding and exerciseable Rollover Common Options. Each Preemptive Holder shall be entitled to purchase such stock or securities on the same terms as such stock or securities are to be offered to third parties; provided that if such third parties are required to also purchase other securities of the Company, Preemptive Holders exercising their rights pursuant to this paragraph shall also be required to purchase the same class and series of securities (in the same proportion and on the same terms and conditions) that such third parties are required to purchase. The purchase price payable for the stock and securities offered to the Preemptive Holders hereunder shall be payable in cash or, to the extent otherwise required hereunder, by notes issued by such holders.

(b) In order to exercise its purchase rights hereunder, each Preemptive Holder must within 15 days after receipt of written notice from the Company describing in reasonable detail the stock or securities being offered, the purchase price thereof, the payment terms and such holder’s percentage allotment deliver a written notice to the Company describing its election hereunder.

(c) Upon the expiration of the offering period described above, the Company shall be entitled to sell such stock or securities which Preemptive Holders have not elected to purchase during the 90 days following such expiration on terms and conditions no more favorable to the purchasers thereof than those offered to such holders. Any stock or securities offered or sold by the Company after such 90-day period must be reoffered to the Preemptive Holders pursuant to the terms of this paragraph.

4. Sale of the Company.

(a) If the Board and the holders of a majority of the shares of Common Stock then outstanding approve a Sale of the Company to an Independent Third Party (an “Approved Sale”), each holder of Stockholder Shares entitled to vote thereon shall vote for, consent to and raise no objections against such Approved Sale. If the Approved Sale is structured as a (i) merger or consolidation, each holder of Stockholder Shares shall waive any dissenters’ rights, appraisal rights or similar rights in connection with such merger or consolidation or (ii) sale of stock, each holder of Stockholder Shares shall agree to sell all of his Stockholder Shares and rights to acquire Stockholder Shares on the terms and conditions approved by the Board and the holders of a majority of the Common Stock then outstanding; provided that such terms and conditions are no less favorable to the Minority Stockholders than the terms and conditions applicable to CHS and its Affiliates and; provided further that CHS may require each of the Minority Stockholders to sell the same percentage of his, her or its securities as CHS is selling of its securities, on the same terms as CHS and its Affiliates. Each holder of Stockholder Shares shall take all necessary or desirable actions in connection with the consummation of the Approved Sale as reasonably requested by the Company.

(b) The obligations of the holders of Stockholder Shares with respect to the Approved Sale of the Company are subject to the satisfaction of the following conditions: (i)

upon the consummation of the Approved Sale, each holder of Stockholder Shares (in his, her or its capacity as such) shall have the right to receive the same form of consideration and the same amount of consideration per share for each class of Stockholder Shares held by such holder applicable to each class; (ii) if any holders of a class of Stockholder Shares are given an option as to the form and amount of consideration to be received or any other right or benefit with respect to the Approved Sale, each holder of such class of Stockholder Shares shall be given the same option, right or benefit (other, in the case of clause (i) or this clause (ii), than any option, right or benefit to be received by a Stockholder on account of such person’s employment relationship with the Company (e.g., stay bonus, noncompetition agreement, right to reinvest or roll over equity, etc.)); and (iii) each holder of then currently exercisable rights to acquire shares of a class of Stockholder Shares shall be given an opportunity to either (A) exercise such rights prior to the consummation of the Approved Sale and participate in such sale as holders of such class of Stockholder Shares or (B) upon the consummation of the Approved Sale, receive in exchange for such rights consideration equal to the amount determined by multiplying (1) the same amount of consideration per share of a class of Stockholder Shares received by holders of such class of Stockholder Shares in connection with the Approved Sale less the exercise price per share of such class of Stockholder Shares of such rights to acquire such class of Stockholder Shares by (2) the number of shares of such class of Stockholder Shares represented by such rights.

(c) Each Stockholder will bear his, her or its pro rata share (based upon the number of shares of Common Stock to be sold) of the reasonable out-of-pocket costs of any sale of Stockholder Shares pursuant to an Approved Sale to the extent such costs are incurred for the benefit of all such holders of Stockholder Shares and are not otherwise paid by the Company or the acquiring party. Costs incurred by the holders of Stockholder Shares on their own behalf will not be considered costs of the Approved Sale. Each Stockholder transferring Stockholder Shares pursuant to an Approved Sale shall be obligated, severally, not jointly, to join on a pro rata basis (based on the number of shares of Common Stock to be sold) in any indemnification or other obligations that are part of the terms and conditions of the Approved Sale (other than any such obligations that relate specifically to a particular Stockholder, such as indemnification with respect to representations and warranties given by a Stockholder regarding such Stockholder’s title to and ownership of Stockholder Shares) (the “Company Indemnity Obligations”). Notwithstanding the foregoing, no Stockholder shall be obligated in connection with any Approved Sale to agree to indemnify or hold harmless the transferees with respect to Company Indemnity Obligations in an amount in excess of the net proceeds paid to such Stockholder in connection with the Approved Sale.

(d) In the event of a sale or exchange by the holders of Stockholder Shares of all or substantially all of the Stockholder Shares by sale, merger, recapitalization, reorganization, consolidation, combination or otherwise, including an Approved Sale. the Company and each Stockholder shall take all necessary and desirable actions in order that each holder of Stockholder Shares shall receive in exchange for such holder’s Stockholder Shares the same portion of the aggregate consideration from such sale or exchange that such holder would have received if such aggregate consideration had been distributed by the Company in complete liquidation pursuant to the rights and preferences set forth in the Company’s Certificate of Incorporation as in effect immediately prior to such sale or exchange.

(e) In order to secure each Minority Stockholder’s obligation to vote his Stockholder Shares entitled to vote thereon and other voting securities of the Company in accordance with the provisions of this Section 4, each Minority Stockholder who is an individual hereby appoints each CHS Director (as in effect from time to time) as his true and lawful proxy and attorney-in-fact, with full power of substitution, to vote all of his Stockholder Shares and other voting securities of the Company for the matters expressly provided for in this Section 4. Each CHS Director may exercise the irrevocable proxy granted to him hereunder at any time any Minority Stockholder who is an individual fails to comply with the provisions of this Section 4. The proxies and powers granted by each Minority Stockholder who is an individual pursuant to this Section 4(e) are coupled with an interest and are given to secure the performance of such Minority Stockholder’s obligations under this Section 4. Such proxies and powers shall be irrevocable for the term set forth in Section 4(f) below, and shall survive the death. incompetency, disability or bankruptcy of such Minority Stockholder and the subsequent holders of his, her or its Stockholder Shares.

5. Legends. Each certificate evidencing Stockholder Shares and each certificate issued in exchange for or upon the transfer of any Stockholder Shares (if such shares remain Stockholder Shares as defined herein after such transfer) shall be stamped or otherwise imprinted with a legend in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A STOCKHOLDERS AGREEMENT DATED AS OF MAY 18, 2004, AMONG THE ISSUER AND CERTAIN OF THE ISSUER’S STOCKHOLDERS. AS SUCH AGREEMENT MAY BE AMENDED, MODIFIED OR SUPPLEMENTED FROM TIME TO TIME. A COPY OF SUCH AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”
