     (i) with respect to the three (3) persons to be elected by the holders of the Series A Stock pursuant to the Certificate of Incorporation (the “Series A Directors”), such directors shall be designated as follows: (A) for so long as Apax holds shares of Series A Stock in an amount equal to at least 50% of the aggregate number of shares of Series A Stock issued to Apax on the Series A Closing Date (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares), then two (2) of the Series A Directors shall be designees of Apax, one of whom shall be Jason Wright as of the date hereof; (B) if, and for so long as, Apax holds shares of Series A Stock in an amount equal to less than 50% of the aggregate number of shares of Series A Stock issued to Apax on the Series A Closing Date (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares), then at least one (1) of the Series A Directors shall be a designee of Apax; (C) for so long as Advance Capital holds shares of Series A Stock in an amount equal to at least 50% of the aggregate number shares of Series A Stock issued to Advance Capital on the Series A Closing Date (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares), then at least one (1) of the Series A Directors shall be a designee of Advance Capital, who shall be Jeffrey Leeds as of the date hereof; and (D) any remaining directors entitled to be elected by the holders of the Series A Stock shall be designated by the holders of a majority of the Series A Stock;

     (iii) with respect to the one (1) director to be elected by the holders of the Common Stock pursuant to the Certificate of Incorporation, such director shall be designated by Winn, who shall be Richard M. Berkeley as of the date hereof; and

     (iv) with respect to the three (3) directors to be elected by the holders of the Common Stock and the Preferred Stock, pursuant to the Certificate of Incorporation (the “Independent Directors”), such directors shall be designated jointly by Apax and Winn upon mutual agreement, who shall be independent directors not affiliated with any Shareholder, and two (2) of whom shall be as of the date hereof Alfred R. Berkeley and Max Hopper (it being understood and agreed that the familial relationship between Alfred R. Berkeley and Richard M. Berkeley does not constitute an affiliation for purposes of this clause (iv)).

     Subject to the fiduciary obligations of each member of the Board of Directors, and so long as the relevant ownership levels set forth above continue to be satisfied, no party hereto shall vote to remove any member of the Board of Directors designated and/or elected in accordance with the aforesaid procedure unless the persons or groups so designating and/or electing such director as specified above so vote or direct that such director shall be removed, and in such event, all parties hereto shall vote in favor of the removal of such director.

     Any vacancy on the Board of Directors created by the resignation, removal, incapacity or death of any person designated under this Section 2(b) shall be filled by another person designated and/or elected in a manner so as to preserve the constituency of the Board of Directors as provided above.

          (c) Notwithstanding the foregoing and in accordance with the Certificate of Incorporation, upon the occurrence of an Event of Default each Shareholder agrees that it will promptly vote its shares of Capital Stock now owned or hereafter acquired by such Shareholder as necessary to cause (i) the removal of the three (3) Independent Directors then serving on the

Board of Directors and (ii) the prompt election to the Board of Directors of three individuals designated by Apax (“Default Directors”) to replace the Independent Directors so removed.

          (d) Each of Apax, Advance Capital and Winn hereby agrees, that for so long as they shall have the right to designate a member of the Board of Directors in accordance with Section 2(b) above, to take all actions, or cause there respective designees to take all actions (including, but not limited to the nomination of specified persons) to cause:

     (i) the Board of Directors to appoint the following individuals to the Compensation Committee of the Board of Directors: Winn and one such Series A Director as may be designated by Apax;

     (ii) the Board of Directors to appoint the following individuals to the Audit Committee of the Board of Directors: Winn and one such Series A Director as may be designated by Apax; and

     (iii) the Board of Directors to appoint, upon the formation of a special committee of the Board of Directors, the following individuals to such special committee: Winn and one such Series A Director as may be designated by Apax; provided, however, that any special committee formed for the purpose of addressing transactions or other matters involving Winn shall not include Winn or any director designated by Winn pursuant to Section 2(b)(ii) or (2)(b)(iii) as a member and any special committee formed for the purpose of addressing transactions or other matters involving Apax shall not include any Series A Director designated by Apax as a member.

          So long as Richard M. Berkeley is a member of the Board of Directors, Mr. Berkeley shall receive notice of and may attend all meetings of the committees of the Board of Directors in a non-voting observer capacity and shall be entitled to receive all reports, presentations and materials as if Mr. Berkeley was a member of any such committee of the Board of Directors. The foregoing shall not be construed to restrict Mr. Berkeley from serving in a voting capacity on any committee of the Board of Directors to which Mr. Berkeley is appointed.

          (e) Notwithstanding anything contained herein or in the Certificate of Incorporation (except for Section IV.7 therein) or bylaws of the Company, with respect to any matter to be voted upon by the Board of Directors, if a majority of the Series A Directors do not vote in favor of such matter, then in order for such matter to be approved, a majority of the members of the Board of Directors, including at least two (2) of the Independent Directors, must vote in favor thereof.

          (f) At any time in which Richard M. Berkeley is not a member of the Board of Directors, the holders of a majority of the Series B Stock may designate one individual (the “Observer”) to attend meetings of the Board of Directors and of all committees of the Board of Directors in a non-voting observer capacity. The Observer shall receive notice of all such meetings and shall be entitled to receive all reports, presentations and materials as if the

Observer was a member of the Board of Directors and such committees of the Board of Directors; provided that an Observer may be excluded from access to any material or meeting or portion thereof if the Company believes that such exclusion is reasonably necessary to preserve the attorney-client privilege, to protect highly confidential proprietary information or for other similar reasons. The Observer shall be subject to the Company’s approval, which approval shall not be unreasonably withheld. Camden will, and will cause the Observer to, hold in confidence and trust, and not use or disclose (except to Camden and its financial, legal or other advisors, provided such advisors agree to hold such confidential information in confidence), any confidential information of the Company provided to or learned by the Observer in connection this paragraph (f).

     3. Advance Capital Redemption.

          (a) The Company agrees that if as of December 31, 2011, (i) the Company has not completed a Liquidation or a Qualified IPO and (ii) the holders of a majority of the shares of the Series A Stock have not given the Company notice to redeem all of the outstanding Series A Stock, in accordance with the Certificate of Incorporation, Advance Capital may prior to January 30, 2011 require the Company to redeem all or any portion of its Series A Stock, in accordance with the procedures set forth herein, so long as, as of the date of each redemption payment, the Company has cash in excess of the amounts of cash projected to be required pursuant to the budget as approved in accordance with Section 11(b) for the three-month period following such payment; provided that if the Company does not make a redemption payment when due, it shall make such payment as soon as the foregoing condition is satisfied; provided further, however, that, notwithstanding the foregoing and Section 7 of the Certificate of Incorporation, the parties agree to vote all Capital Stock of the Company now owned or hereafter acquired by such party, and the Company agrees to use reasonable efforts (1) to authorize and issue Capital Stock of the Company which shall be junior and subordinate to the Series A Stock, the Series A1 Stock, the Series B Stock and the Series C Stock and (2) to sell such Capital Stock in order to raise funds necessary to redeem the Series A Stock of Advance Capital if the Company cannot pay the Redemption Price because of any failure of the Company to satisfy a condition set forth in this Section 3(a). The Company’s inability to pay the Redemption Price to Advance Capital shall not be deemed an Event of Default by the Company.

          (b) If Advance Capital wishes to elect the Company to redeem all or any portion of its Series A Stock pursuant to this Section 3, Advance Capital shall send written notice to the Company, at least one hundred and eighty (180) days prior to the intended date of redemption of such Series A Stock (the “Series A Redemption Date”), setting forth the number of shares to be redeemed; provided, however, that if during such one hundred and eighty (180) day period, the holders of a majority of the shares of the Series A Stock require the Company to redeem all or any portion of the outstanding Series A Stock by giving appropriate notice, then the shares of Series A Stock of Advance Capital shall be redeemed with the shares of Series A Stock of the remaining holders and the Series A Redemption Date shall be delayed to coincide with the redemption date of the other Series A Shareholders, in accordance with the Certificate of Incorporation.

          (c) The Company shall redeem the Series A Stock which Advance Capital has elected to have redeemed at the Redemption Price and in accordance with the procedures provided for in the Certificate of Incorporation without giving effect to any amendments thereto after the date hereof (unless the Company shall have obtained written consent of the holders of a majority of the Capital Stock held by Advance Capital); provided that if Advance Capital does not agree with the determination of Fair Market Value (as defined in the Certificate of Incorporation) of the Series A Stock, the Fair Market Value shall be based upon a valuation of an independent third party duly qualified to perform such valuations, chosen by mutual agreement between the Company and Advance Capital.

          (d) Nothing in this Section 3 shall limit any of Advance Capital’s rights under the Certificate of Incorporation.

     3A. Apax Voting Provision. Apax shall not vote in favor of or grant its consent to any action contemplated by Section IV.7A of the Company’s Certificate of Incorporation that requires either the consent of holders of 90% of the Series A Stock or the approval of all of the directors elected by the holders of the Series A Stock (the “Specified Actions”) without obtaining the written consent of Advance Capital Management LLC (or any Affiliate thereof designated by Advance Capital Management LLC in connection with Advance Capital Management LLC’s dissolution) to vote in favor of or to grant consent to such action; provided that Apax shall not be so restricted in voting or granting its consent if Apax’s voting in favor of or granting of consent to a Specified Action would result in the holders of 90% of the then outstanding Series A Stock voting in favor of or consenting to such Specified Action.

     4. Sale of the Company.

          (a) If, at any time, after December 31, 2011 the Series A Directors designated by Apax and all of the Independent Directors determine it is appropriate to conduct a Sale of the Company, then the Company shall undertake reasonable steps to solicit offers for a Sale of the Company, including retaining an investment banker.

          (b) If the conditions set forth in Section 4(a) have been satisfied and the Company receives a bona fide offer to purchase either all of its Capital Stock or all or substantially all of its assets (including by means of a merger or consolidation) at a price which results in (i) the Series A Shareholders receiving at least 3.5 times the Series A Issue Price per share of Series A Stock and (ii) the remaining shareholders receiving the amount they would have received upon a Liquidation of the Company in accordance with the Certificate of Incorporation, which resulted in the Series A Shareholders receiving such amount, then Winn shall vote all of his shares of Series A1 Stock and Common Stock for approval of such Sale of the Company and shall agree to sell such Capital Stock if the transaction is in the form of a sale of stock; provided, however, that Winn shall not be obligated by this Section 4(b) if either (A) the offer or transaction referenced in this Section 4(b) is revised, or circumstances under which the transaction would be consummated change, such that such transaction, if consummated, would fail to satisfy the requirements of this Section 4(b), or (B) for any reason the Warrants would not vest and become exercisable in their entirety prior to or in connection with such transaction, so long as the Warrants shall not have expired in accordance with their terms.

     5. Restrictions on Transfer. No Shareholder shall Transfer any Capital Stock of the Company or any interest therein to any Person except (a) subject to Section 15(a), pursuant to a Permissible Transfer (as defined below) or (b) if the Transfer complies with Section 6 and, if applicable, Section 7 hereof, and, unless in each case, the Transfer complies with applicable federal and state securities laws.

     (ii) any Person receiving such Capital Stock of the Company from such Shareholder at such Shareholder’s death pursuant to a will or the laws of intestate succession, provided that under the terms of such will or under the applicable laws of intestate succession, such Capital Stock of the Company is Transferred solely to one or more Persons otherwise referenced in this Section 5(a);

     (iii) any trust or limited partnership established for the benefit of any of the foregoing; or

     (iv) another Person that such transferring Shareholder or previous Permissible Transferee of such Shareholder set forth in (i) through (iii) of this subparagraph (a) controls or manages, is controlled or managed by or is under common management or control with, whether through ownership of equity interests, by contract or otherwise;

          (b) each Shareholder which is not an individual may Transfer its Capital Stock of the Company (i) to another Person that such transferring Shareholder controls or manages, is controlled or managed by or is under common management or control with, whether through ownership of equity interests, by contract or otherwise or (ii) to such Shareholder’s members or partners, in a transaction in which all of such Shareholder’s Capital Stock of the Company is so Transferred;

     For purposes hereof, the Persons described in paragraphs (a) and (b)(i) above with regard to a Shareholder shall be deemed “Affiliates” of such Shareholder.

          (c) each Shareholder may Transfer its shares of Capital Stock to the Company; and

     6. Right of First Offer.

          (a) Except for a Permissible Transfer, if, at any time after the date hereof, a Shareholder (the “ROFO Seller”) desires to Transfer any or all of its shares of Capital Stock of the Company (the “Offered Securities”) other than pursuant to Section 4 or a Sale of the Company approved by the requisite vote of the members on the Company’s Board of Directors and the Shareholders, then such ROFO Seller shall deliver a written notice to the other Preferred Shareholders (the “Offer Notice”) of the ROFO Seller’s desire to Transfer such Offered Securities. The Offer Notice shall disclose (i) the identity of the Proposed Transferee, if any, (ii) the number of Offered Securities proposed to be Transferred, (iii) the terms and conditions of the proposed Transfer of the Offered Securities, including the price per share to be paid, and (iv) any other material facts relating to the proposed Transfer.

          (b) Upon receipt of the Offer Notice, each Preferred Shareholder shall have the right and option to elect to purchase, at the price and on the terms stated in the Offer Notice, such Preferred Shareholders’ pro rata portion of the total number of Offered Securities equal to the product obtained by multiplying (i) the Offered Securities, by (ii) a fraction, the numerator of which is the number of shares held by such Preferred Shareholder (calculated on an as converted basis) and the denominator of which is the sum of the total number of shares of Capital Stock of the Company at that time owned by such Preferred Shareholder and all other Preferred Shareholders electing to purchase Offered Securities (calculated on an as converted basis) in accordance with Section 6(c). If (x) any Preferred Shareholder has delivered an Offer Acceptance (as defined below) providing for such Preferred Shareholder to purchase its full pro rata portion of the Offered Securities (each such Preferred Shareholder, a “Pro Rata Purchaser”) and (y) not all of the Offered Securities have been proposed to be purchased pursuant to all Offer Acceptances, then the Company shall deliver a written notice (the “Supplemental Offer Notice”) to the Pro Rata Purchasers within five (5) days after the expiration of the ten (10) Business Day period described in clause (c) below, and all Pro Rata Purchasers shall have the right to purchase any remaining Offered Securities, which shall, if necessary, be allocated pro rata among the Pro Rata Purchasers according to their holdings of the Company’s shares of Capital Stock (determined on an as converted basis), which right to purchase shall be exercised by a Pro Rata Purchaser delivering a supplemental written notice (a “Supplemental Offer Acceptance”) to the Company within five (5) days after delivery of the Supplemental Offer Notice setting forth the greatest number of remaining Offered Securities such Pro Rata Purchaser desires to purchase. Notwithstanding any provision of this Section 6 to the contrary, if the Preferred Shareholders collectively fail to elect to purchase all of the Offered Securities, then no Preferred Shareholder shall have the right to purchase any Offered Securities.

          (c) Any election to purchase Offered Securities shall be made by written notice (an “Offer Acceptance”) to the ROFO Seller and the Company within ten (10) Business Days following delivery of the Offer Notice stating the greatest number of Offered Securities such Preferred Shareholder is willing to purchase. Thereupon, or, if applicable, the day after the expiration of the five (5) day period for delivery of the Supplemental Offer Acceptance, the ROFO Seller shall sell the Offered Securities to any Preferred Shareholder which has timely delivered an Offer Acceptance, at the price and on the terms stated in the Offer Notice.

          (d) If the Preferred Shareholders fail to purchase in the aggregate all of the Offered Securities, the ROFO Seller may proceed with a sale of the Offered Securities within ninety (90) Business Days after the Offer Notice, subject to full compliance with Section 7 hereof, to any Person reasonably acceptable to the Company for the price and on the terms specified in the Offer Notice. If the Offered Securities are not sold pursuant to the provisions of this Section 6 such Capital Stock shall again be subject to the restrictions contained in this Agreement and shall not be Transferred, except in compliance with the applicable provisions of this Agreement.

     7. Co-Sale Rights.

          (a) The Series A Shareholders, the Series B Shareholders and the Series C Shareholders may elect to participate in the transaction contemplated by Section 6(d) with respect to a Transfer of any Offered Securities owned by any holder of Series A1 Preferred Stock or any shares of Capital Stock owned, directly or indirectly, by Winn (the “Co-Sale Securities”), except for a Permissible Transfer. For purposes of this Section 7, Winn and any holder of Series A1 Stock who has delivered an Offer Notice shall be referred to as the “Co-Sale Seller.”

          (b) Upon receipt of the Offer Notice described in Section 6 above with respect to an offer to sell Co-Sale Securities, each Series A Shareholder, each Series B Shareholder and each Series C Shareholder shall have the right and option during the twenty (20) Business Day period following receipt of the Offer Notice to elect to sell, at the price and on the same terms and conditions stated in the Offer Notice, a number of shares of Series A Stock, Series B Stock or Series C Stock, as applicable, equal to the product obtained by multiplying (i) the Co-Sale Securities subject to the Offer Notice (calculated on an as converted basis), by (ii) a fraction, the numerator of which is the number of shares of Series A Stock held by such Series A Shareholder (calculated on an as converted basis), the number of shares of Series B Stock held by such Series B Shareholder (calculated on an as converted basis), or the number of shares of Series C Stock held by such Series C Shareholder (calculated on an as converted basis), as applicable, and the denominator of which is the sum of the total number of shares of Capital Stock of the Company at that time owned by such Series A Shareholder, Series B Shareholder or Series C Shareholder, as applicable, and all other holders of Preferred Stock (including the Co-Sale Seller and calculated on an as converted basis) electing to sell.

          (c) Any such election shall be made by written notice (a “Co-Sale Acceptance”) to the Co-Sale Seller within twenty (20) Business Days following delivery of the Offer Notice. Thereupon, the Co-Sale Seller shall not sell any of the subject Co-Sale Securities until each Series A Shareholder, Series B Shareholder and Series C Shareholder who has timely delivered a Co-Sale Acceptance shall have been afforded the opportunity to sell its pro rata share (calculated pursuant to paragraph (b) above) of its shares of Series A Stock, Series B Stock or Series C Stock, as applicable, in respect of which such Co-Sale Acceptance shall have been delivered, at the price and on the same terms and conditions as set forth in the Offer Notice to the same purchaser as identified by the Co-Sale Seller. To the extent one or more holders of Series A Stock, Series B Stock or Series C Stock exercise their right of participation in accordance with the terms and conditions set forth in this Section 7, the number of Co-Sale Securities that the Co-Sale Seller may sell hereby shall be correspondingly reduced. If any of the holders of Series A

Stock, Series B Stock or Series C Stock do not provide a Co-Sale Acceptance pursuant to this Section 7(c) in respect of their pro rata share of the Co-Sale Securities, the Co-Sale Seller may proceed with a sale of the Co-Sale Securities within ninety (90) Business Days of the Offer Notice, pursuant to Section 6(d). Any Series A Stock, Series B Stock or Series C Stock not sold pursuant to the provisions of this Section 7 shall again be subject to the restrictions contained in this Agreement and shall not thereafter be Transferred, except in compliance with the applicable provisions of this Agreement.

          (d) All fees, costs and expenses incurred in connection with a Transfer under this Section 7 in which a Series A Shareholder, Series B Shareholder or Series C Shareholder participates shall be borne ratably by those sellers participating in such sale, provided that each seller shall be responsible for the fees and disbursements of its own legal counsel in connection with such sale.

     8. Pre-emptive Rights.

          (a) If at any time after the date hereof, the Company wishes to issue any shares, interests, participations, rights in or other equivalents (however designated and whether voting or non-voting) of the Company’s capital stock or any rights, warrants or options exercisable or exchangeable for or convertible into such capital stock (the “Pre-emptive Securities”) to any Person, the Company shall promptly deliver a notice of its intention to effect such issuance (the “Notice of Intention to Sell”) to the holders of Series A Stock, so long as at least 7,903,125 shares of Series A Stock are outstanding (as adjusted for any combinations, divisions or similar recapitalizations affecting such shares), to the holders of Series B Stock, so long as at least 812,500 shares of Series B Stock are outstanding (as adjusted for any combinations, divisions or similar recapitalizations affecting such shares), to the holders of Series C Stock, so long as at least 750,000 shares of Series C Stock are outstanding (as adjusted for any combinations, divisions or similar recapitalizations affecting such shares), and to the holders of Series A1 Stock, so long as at least 5,050,000 shares of the Series A1 Stock are outstanding (as adjusted for any combinations, divisions or similar recapitalizations affecting such shares) (collectively, each are referred to herein as an “Eligible Shareholder”), setting forth a description of the Capital Stock to be issued, the proposed purchase price thereof and terms of the sale (a “Pre-emptive Sale”). Upon receipt of the Notice of Intention to Sell, each Eligible Shareholder shall have the right to elect to purchase, at the price and on the terms stated in the Notice of Intention to Sell, the number of the shares of Capital Stock equal to the product of (i) a fraction, the numerator of which is such Eligible Shareholder’s aggregate ownership of shares of Common Stock (assuming conversion of all shares of Preferred Stock) and the denominator of which is the number of shares held by all holders of Capital Stock of the Company (calculated on a fully-diluted basis but only including options or warrants which are then currently exercisable), multiplied by (ii) the number of shares of Pre-emptive Securities to be issued (calculated on an as converted basis). Such election is to be made by the Eligible Shareholders by written notice to the Company within thirty (30) Business Days after receipt by the Eligible Shareholders of the Notice of Intention to Sell. Each Eligible Shareholder shall also have the option, exercisable by so specifying in such written notice, to purchase on a pro rata basis similar to that described above, any remaining number of shares of Capital Stock of the Company subject to purchase by Eligible Shareholders under this Section 8(a) (the “Maximum Pre-emptive Number”) not

purchased by other Eligible Shareholders, in which case the Eligible Shareholders exercising such further option shall be deemed to have elected to purchase such remaining portion of the Maximum Pre-emptive Number of shares of Capital Stock of the Company on such pro rata basis, up to the Maximum Pre-emptive Number of shares of Capital Stock of the Company which such Eligible Shareholder shall have specified until either (A) no Eligible Shareholder shall have elected to purchase any further amount of the shares of Capital Stock of the Company which are the subject of the Notice of Intention to Sell or (B) the Maximum Pre-emptive Number of shares of Capital Stock of the Company shall have been subscribed for by the Eligible Shareholder(s). The Company shall promptly notify each electing Eligible Shareholder in writing of each notice of election received from other Eligible Shareholders pursuant to this Section 8(a).

          (b) If an Eligible Shareholder gives the Company notice, pursuant to the provisions of this Section 8, that such Eligible Shareholder desires to purchase any of the shares of Capital Stock of the Company, payment therefor shall be by check or wire transfer, against delivery of the securities at the executive offices of the Company not later than the closing date for the Pre-emptive Sale. The Company shall give each Eligible Shareholder not less than five (5) Business Days prior written notice of the closing date for the Pre-emptive Sale, together with appropriate payment instructions.

          (c) The pre-emptive rights contained in this Section 8 shall not apply to (i) Pre-emptive Securities that are not ultimately sold by the Company and (ii) Capital Stock of the Company issued in any of the following circumstances: (A) shares of Common Stock issued upon the conversion of the Preferred Stock, (B) shares of Common Stock issued in connection with any stock split or stock dividend, (C) shares of Common Stock issued or issuable upon exercise (in accordance with the terms thereof) of the Warrants, (D) shares of Common Stock issuable upon the exercise of stock options or other awards made or denominated in shares of Common Stock under any of the Company’s stock plans for employees, consultants or directors including any stock option, stock purchase, restricted stock or similar plan hereafter adopted by the Board of Directors and, if required by applicable law, approved by the stockholders of the Company, (E) shares of Common Stock issuable upon the exercise of warrants for the purchase of up to an aggregate of 600,000 shares of Common Stock issued from time to time to significant customers of the Company, (F) 5% of the outstanding Common Stock or other equivalents of the Common Stock (on a fully diluted basis) issued pursuant to a strategic partnership, joint venture, and similar arrangements, the acquisition of a business (including, without limitation, by way of an acquisition of capital stock) or the assets of a business (which assets do not consist primarily of cash or cash equivalents), research and development agreement, product development or marketing agreement or similar arrangement, in any case as approved by the Board of Directors and (G) pursuant to a Qualified IPO.

          (d) If the Company, having complied with the provisions of this Section 8, fails to consummate the sale or issuance of Capital Stock within ninety (90) days following the expiration of the time provided above for exercise of the preemptive rights set forth in this Section 8, such Capital Stock of the Company, as the case may be, shall again be subject to all of the restrictions of this Agreement.

          (e) Any Shareholder’s rights under Section 8 may be exercised by any Affiliate which agrees to become a party to the Agreement upon its acquisition of the Company’s Capital Stock.

     9. Public Offering. The parties hereto agree that, in connection with an underwritten public offering by the Company of any its Capital Stock, if agreed to by a majority of the holders of each class or series of Capital Stock of the Company, they shall not sell any shares of Capital Stock of the Company during the period commencing ten (10) days prior to any such underwritten offering and ending one hundred and eighty (180) days following any such underwritten offering (or for such shorter period of time as is sufficient and appropriate, in the opinion of the managing underwriter) and if so requested by the managing underwriter they shall execute an agreement with respect to the foregoing.

     10. Restrictive Legends on Capital Stock.

          (a) Each certificate evidencing shares of Capital Stock (including each certificate evidencing shares of Preferred Stock held by subsequent transferees of any such certificate), shall be stamped or otherwise imprinted with a legend in substantially the following form:

THE OFFER AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED PURSUANT TO THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAW. NEITHER THE SECURITIES NOR ANY PORTION THEREOF OR INTEREST THEREIN, MAY BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS THE SAME IS REGISTERED AND QUALIFIED IN ACCORDANCE WITH SAID ACT AND ANY APPLICABLE STATE SECURITIES LAW, OR, IN THE OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY, SUCH REGISTRATION AND QUALIFICATION ARE NOT REQUIRED.

          (b) Each certificate evidencing shares of Capital Stock (including each certificate evidencing shares of Preferred Stock held by subsequent transferees of any such certificate), shall also be stamped or otherwise imprinted with a legend (for so long a such legend may be applicable) in substantially the following form:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A SHAREHOLDERS AGREEMENT AMONG THE COMPANY AND CERTAIN OF ITS SHAREHOLDERS, AS AMENDED AND MODIFIED FROM TIME TO TIME. A COPY OF SUCH SHAREHOLDERS AGREEMENT SHALL BE FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST.

          (c) Each certificate evidencing shares of Preferred Stock issued upon any Transfer (and each certificate evidencing any untransferred balance of such securities) shall bear the legends set forth above unless, with regard to the legend described in Section 10(b) above,

such securities are no longer subject to this Agreement and, with regard to the legend described in Section 10(a) above, (i) in the opinion of counsel (which opinion is reasonably acceptable to the Company) addressed to the Company the registration of future Transfers is not required by the applicable provisions of the Securities Act or applicable state securities laws; (ii) the Company shall have waived the requirement of such legend; or (iii) in the reasonable opinion of counsel to the Company, such Transfer shall have been made in connection with an effective registration statement filed pursuant to the Securities Act or an exemption therefrom.

     Apax, Advance Capital, Camden and Winn will, and will instruct each of their respective Affiliates and advisors to, hold in confidence all such information, will use such information only in connection with governing the affairs of the Company and, if this Agreement is terminated in accordance with its terms, will deliver promptly to the Company all copies of such information (and any copies, compilations or extracts thereof or based thereon) then in their possession or under their control.

     12. Termination. Upon the consummation of a Qualified IPO, distribution of all assets of the Company pursuant to a Liquidation, a redemption of all of the outstanding Series A Stock, Series B Stock and Series C Stock or a conversion of all of the outstanding Series A Stock, Series A1 Stock, Series B Stock and Series C Stock, this Agreement shall terminate.

     13. Aggregation of Stock. With respect to any Shareholder, all shares of Series A Stock, Series A1 Stock, Series B Stock, Series C Stock and Common Stock held or acquired by any Affiliate of such Shareholder shall be aggregated together with any shares held by such Shareholder for the purpose of determining the availability of any rights under this Agreement.

The Company and the other parties hereto agree that monetary damages may not be adequate compensation for any loss incurred by reason of a breach of any of the provisions of this Agreement and hereby agree to waive the defense in any action for specific performance that a remedy at law would be adequate.

          (c) The Company further agrees that it shall be a condition precedent to any future issuance of Capital Stock that the Person to whom such Capital Stock of the Company is to be issued becomes subject to the terms and conditions of this Agreement as a Shareholder and agrees in writing to be bound hereby, except with respect to any Capital Stock of the Company issued upon the exercise of stock options or other awards made under any of the Company’s stock plans and any Capital Stock of the Company issued pursuant to a strategic partnership, joint venture, and similar arrangements, the acquisition of a business (including, without limitation, by way of an acquisition of capital stock) or the assets of a business (which assets do not consist primarily of cash or cash equivalents), research and development agreement, product development or marketing agreement or similar arrangement, in any case as approved by the Board of Directors pursuant to Section 8(c)(ii)(F) above.
