No transfer of any such shares in violation hereof shall be made or recorded on the books of the Company and any such transfer shall be void ab initio and of no effect.

4. Right of First Refusal. (a) If, at any time after the Lapse Date and prior to the date of consummation of a Qualified Public Offering, the Director Stockholder receives a bona fide offer to purchase any or all of his Stock (the “Third Party Offer”) from a third party (which, for the avoidance of doubt, shall not include any transfers pursuant to clauses (y) and (z) of Section 2(a) or pursuant to the Sale Participation Agreement) (the “Offeror”), which the Director Stockholder wishes to accept, the Director Stockholder shall cause the Third Party Offer to be reduced to writing and shall notify the Company in writing of his wish to accept the Third Party Offer. The Director Stockholder’s notice to the Company shall contain an irrevocable offer to sell such Stock to the Company (in the manner set forth below) at a purchase price equal to the price contained in, and on the same terms and conditions of, the Third Party Offer, and shall be accompanied by a copy of the Third Party Offer (which shall identify the Offeror). At any time within fifteen (15) days after the date of the receipt by the Company of the Director Stockholder’s notice, the Company shall have the right and option to purchase, or to arrange for a third party to purchase, all (but not less than all) of the shares of Stock covered by the Third Party Offer, pursuant to Section 4(b).

(b) The Company shall have the right and option to purchase, or to arrange for a third party to purchase, all of the shares of Stock covered by the Third Party Offer at the same price and on substantially the same terms and conditions as the Third Party Offer (or, if the Third Party Offer includes any consideration other than cash, then at the sole option of the Company, at the equivalent all cash price, determined in good faith by the Company’s Board), by delivering a certified bank check or checks in the appropriate amount (or by wire transfer of immediately available funds, if the Director Stockholder Entities provide to the Company wire transfer instructions) (and any such non-cash consideration to be paid) to the Director Stockholder at the principal office of the Company against delivery of certificates or other instruments representing the shares of Stock so purchased, appropriately endorsed by the Director Stockholder. If at the end of the 15-day period, the Company has not tendered the purchase price for such shares in the manner set forth above, the Director Stockholder may, during the succeeding 60-day period, sell not less than all of the shares of Stock covered by the Third Party Offer, to the Offeror on terms no less favorable to the Director Stockholder than those contained in the Third Party Offer. Promptly after such sale, the Director Stockholder shall notify the Company of the consummation thereof

4

and shall furnish such evidence of the completion and time of completion of such sale and of the terms thereof as may reasonably be requested by the Company. If, at the end of sixty (60) days following the expiration of the 15-day period during which the Company is entitled hereunder to purchase the Stock, the Director Stockholder has not completed the sale of such shares of the Stock as aforesaid, all of the restrictions on sale, transfer or assignment contained in this Agreement shall again be in effect with respect to such shares of the Stock.

Company) to the Investor Stockholder Agreement, subject to applicable and customary underwriter restrictions; provided, however, that at no time shall the Director Stockholder have any rights to request registration under Section 5.3 of the Investor Stockholders Agreement; and provided further, that the Director Stockholder shall not be bound by any amendments to the Investor Stockholder Agreement unless the Director Stockholder consents in writing thereto provided that such consent will not be unreasonably withheld.

(b) In the event of a sale of Common Stock by the Company in accordance with the terms of the Investor Stockholder Agreement, the Company will promptly notify the Director Stockholder in writing (a “Notice”) of any proposed registration (a “Proposed Registration”). If within fifteen (15) days of the receipt by the Director Stockholder of such Notice, the Company receives from the applicable Director Stockholder Entities a written request (a “Request”) to register shares of Stock held by the applicable Director Stockholder Entities (which Request will be irrevocable unless otherwise mutually agreed to in writing by the Director Stockholder and the Company), shares of Stock will be so registered as provided in this Section 9; provided, however, that for each such registration statement only on Request, which shall be executed by the applicable Director Stockholder Entities, may be submitted for all Registrable Securities held by the applicable Director Stockholder Entities.

(c) The maximum number of shares of Stock which will be registered pursuant to a Request will be the lowest of (i) the number of shares of Stock then held by the Director Stockholder Entities, including all shares of Stock which the Director Stockholder Entities are then entitled to acquire under an unexercised portion of the Options to the extent then exercisable, multiplied by a fraction, the numerator of which is the number of shares of Stock being sold by the Company and any affiliated or unaffiliated investment partnerships and investment limited liability companies investing with the Company and the denominator of which is the aggregate number of shares of Stock owned by the Company and any investment partnerships and investment limited liability companies investing with the Company or (ii) the maximum number of shares of Stock which the Company can register in connection with such Request in the Proposed Registration without adverse effect on the offering in the view of the managing underwriters (reduced pro rata as more fully described in subsection (d) of this Section 9 or (iii) the maximum number of shares which the Director Stockholder (pro rata based upon the aggregate number of shares of Stock the Director Stockholder and all Other Director Stockholders have requested to be registered) is permitted to register under the Piggyback Registration Rights.

(d) If a Proposed Registration involves an underwritten offering and the managing underwriter advises the Company in writing that, in its opinion, the number of shares of Stock requested to be included in the Proposed Registration exceeds the number which can be sold in such offering, so as to be likely to have an adverse effect on the price, timing or distribution of the shares of Stock offered in such Public Offering as contemplated by the Company, then the Company will include in the Proposed Registration (i) first, 100% of the shares of Stock the Company proposes to sell and (ii) second, to the extent of the number of shares of Stock requested to be included in such registration which, in the opinion of such managing underwriter, can be sold without having the adverse effect referred to above, the number of shares of Stock which the selling Investors and any affiliated or unaffiliated investment partnerships and investment limited liability companies investing with the selling Investors, the Director Stockholder and all Other Director Stockholders (together, the “Holders”) have requested to be included in the Proposed Registration, such amount to be allocated pro rata among all requesting Holders on the basis of the relative number of shares of Stock then held by each such Holder (including upon exercise of any exercisable portion of the Options) (provided that any shares thereby allocated to any such Holder that exceed such Holder’s request will be reallocated among the remaining requesting Holders in like manner).

(e) Upon delivering a Request the Director Stockholder will, if requested by the Company, execute and deliver a custody agreement and power of attorney having customary terms and in form and

8

substance reasonably satisfactory to the Company with respect to the shares of Stock to be registered pursuant to this Section 9 (a “Custody Agreement and Power of Attorney”). The Custody Agreement and Power of Attorney will provide, among other things, that the Director Stockholder will deliver to and deposit in custody with the custodian and attorney-in-fact named therein a certificate or certificates (to the extent applicable) representing such shares of Stock (duly endorsed in blank by the registered owner or owners thereof or accompanied by duly executed stock powers in blank) and irrevocably appoint said custodian and attorney-in-fact as the Director Stockholder’s agent and attorney-in-fact with full power and authority to act under the Custody Agreement and Power of Attorney on the Director Stockholder’s behalf with respect to the matters specified therein.

(f) The Director Stockholder agrees that he will execute such other agreements as the Company may reasonably request to further evidence the provisions of this Section 9.

10. Pro Rata Repurchases; Dividends. (a) Notwithstanding anything to the contrary contained in Section 4, if at any time consummation of any purchase or payment to be made by the Company pursuant to this Agreement and the Other Director Stockholders Agreements would result in an Event, then the Company shall make purchases from, and payments to, the Director Stockholder and Other Director Stockholders pro rata (on the basis of the proportion of the number of shares of Stock each such Director Stockholder and all Other Director Stockholders have elected or are required to sell to the Company) for the maximum number of shares of Stock permitted without resulting in an Event (the “Maximum Repurchase Amount”). Until all of such Stock is purchased and paid for by the Company, the Director Stockholder and the Other Director Stockholders whose Stock is not purchased in accordance with this Section 10(a) shall have priority, on a pro rata basis, over other purchases of Stock by the Company pursuant to this Agreement and Other Director Stockholders’ Agreements.

Nothing in this Agreement shall be deemed to restrict or prohibit the Company from purchasing, redeeming or otherwise acquiring for value shares of Stock or Options from the Director Stockholder, at any time, upon such terms and conditions, and for such price, as may be mutually agreed upon in writing between the Parties, whether or not at the time of such purchase, redemption or acquisition circumstances exist which specifically grant the Company the right to purchase, or the Director Stockholder the right to sell, shares of Stock or any Options under the terms of this Agreement; provided that no such purchase, redemption or acquisition shall be consummated, and no agreement with respect to any such purchase, redemption or acquisition shall be entered into, without the prior approval of the Board.

12. Covenant Regarding 83(b) Election. Except as the Company may otherwise agree in writing, the Director Stockholder hereby covenants and agrees that he will make an election provided pursuant to Treasury Regulation 1.83-2 with respect to the Stock, including without limitation, the Stock to be acquired upon each exercise of the Director Stockholder’s Options and any grant of Restricted Stock; and Director Stockholder further covenants and agrees that he will furnish the Company with copies of the forms of election the Director Stockholder files within thirty (30) days after the date hereof, and within thirty (30) days after each exercise of Director Stockholder’s Options and with evidence that each such election has been filed in a timely manner.
