NOW THEREFORE, to implement the foregoing and in consideration of the grant of Options and of the mutual agreements contained herein, the Parties agree as follows:

1. Issuance of Options; Purchased Stock; Purchases of Additional Common Stock.

(a) The Management Stockholder hereby subscribes for, as of the Effective Date, and the Company shall issue to the Management Stockholder as of the Effective Date,                      shares of Common Stock, at a per share price of $10.00 (the “Base Price”), which price is equal to the fair market value of the shares of the Company on the Effective Date as determined by the Board and supported by a valuation of the Company by an independent third party appraiser (all such shares acquired by the Management Stockholder, the “Purchased Stock”). The aggregate price for all shares of the Purchased Stock is $                    .

(b) Subject to the terms and conditions hereinafter set forth and as set forth in the Option Plan, as of the Effective Date, the Company is issuing to the Management Stockholder Options to acquire shares of Common Stock at an initial Option Exercise Price equal to (i) the Base Price and (ii) the Base Price multiplied by two, and the Parties shall execute and deliver to each other copies of the Stock Option Agreement concurrently with the issuance of the Options.

(c) The Company shall have no obligation to issue any Purchased Stock or issue any Options to any person who (i) is a resident or citizen of a state or other jurisdiction in which the sale of the Common Stock to him or her would constitute a violation of the securities or “blue sky” laws of such jurisdiction or (ii) is not an employee of the Company or any of its subsidiaries on the date hereof.

2. Management Stockholder’s Representations, Warranties and Agreements.

(a) In addition to agreeing to and acknowledging the restrictions on transfer of the Stock (as defined in Section 3(a) hereof) set forth in Section 3 hereof, if the Management Stockholder is a Rule 405 Affiliate, the Management Stockholder also agrees and acknowledges that he will not transfer any shares of the Stock unless:

(i) the transfer is pursuant to an effective registration statement under the Securities Act of 1933, as amended, and the rules and regulations in effect thereunder (the “Act”), and in compliance with applicable provisions of state securities laws; or

(ii) (A) counsel for the Management Stockholder (which counsel shall be reasonably acceptable to the Company) shall have furnished the Company with an opinion, satisfactory in form and substance to the Company, that no such registration is required because of the availability of an exemption from registration under the Act and (B) if the Management Stockholder is a citizen or resident of any country other than the United States, or the Management Stockholder desires to effect any transfer in any such country, counsel for the Management Stockholder (which counsel shall be reasonably satisfactory to the Company) shall have furnished the Company with an opinion or other advice reasonably satisfactory in form and substance to the Company to the effect that such transfer will comply with the securities laws of such jurisdiction.

2

Notwithstanding the foregoing, the Company acknowledges and agrees that any of the following transfers are deemed to be in compliance with the Act and this Agreement (including without limitation any restrictions or prohibitions herein) and no opinion of counsel is required in connection therewith: (x) a transfer permitted by or made pursuant to Sections 3 or 4 hereof, (y) a transfer upon the death or Permanent Disability of the Management Stockholder to the Management Stockholder’s Estate or a transfer to the executors, administrators, testamentary trustees, legatees or beneficiaries of a person who has become a holder of Stock in accordance with the terms of this Agreement; provided that it is expressly understood that any such transferee shall be bound by the provisions of this Agreement, and (z) a transfer made after the Effective Date in compliance with applicable securities laws to a Management Stockholder’s Trust, provided that such transfer is made expressly subject to this Agreement and that the transferee agrees in writing to be bound by the terms and conditions hereof.

(b) The Management Stockholder acknowledges that he has been advised that a notation shall be made in the appropriate records of the Company indicating that the Stock is subject to restrictions on transfer. If the Management Stockholder is a Rule 405 Affiliate, the Management Stockholder also acknowledges that (1) the Stock must be held indefinitely and the Management Stockholder must continue to bear the economic risk of the investment in the Stock unless it is subsequently registered under the Act or an exemption from such registration is available, (2) when and if shares of the Stock may be disposed of without registration in reliance on Rule 144 of the rules and regulations promulgated under the Act, such disposition can be made only in limited amounts in accordance with the terms and conditions of such rule and (3) if the Rule 144 exemption is not available, public sale without registration will require compliance with some other exemption under the Act.

(c) If any shares of the Stock are to be disposed of in accordance with an applicable resale exemption or otherwise, the Management Stockholder shall promptly notify the Company of such intended disposition and shall deliver to the Company at, or prior to, the time of such disposition such documentation as the Company may reasonably request in connection with such sale and, in the case of a disposition pursuant to Rule 144, shall deliver to the Company an executed copy of any notice on Form 144 required to be filed with the SEC.

(d) The Management Stockholder agrees that, if any shares of the Stock are offered to the public pursuant to an effective registration statement under the Act (other than registration of securities issued on Form S-8, S-4 or any successor or similar form), the Management Stockholder will not effect any public sale or distribution of any shares of the Stock (except pursuant to such registration statement) for the “Lock-Up Period,” unless otherwise agreed to in writing by the Company. The “Lock-Up Period” is the period (i) beginning on the date of the receipt of a notice from the Company that the Company has filed, or imminently intends to file, such registration statement and (ii) ending one hundred and eighty (180) days (or such shorter period as may be consented to by the managing underwriter or underwriters) in the case of the initial Public Offering and ninety (90) days (or such shorter period as may be consented to by the managing underwriter or underwriters, if any) in the case of any other Public Offering after the effective date of such registration statement. Notwithstanding the foregoing, if (1) during the last seventeen (17) days of the Lock-Up Period, the Company issues an earnings release or material news or a material event relating to the Company occurs or (2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results

3

during the 16-day period beginning on the last day of the Lock-Up Period, then the restrictions imposed in this Section 2(d) shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the announcement of the material news or the occurrence of the material event, unless the Company waives such extension in writing.

(e) The Management Stockholder represents and warrants that (i) with respect to the Stock, he has received and reviewed the available information relating to the Stock, including having received and reviewed the documents related thereto, certain of which documents set forth the rights, preferences and restrictions relating to the Options and the Stock underlying the Options and (ii) he has been given the opportunity to obtain any additional information or documents and to ask questions and receive answers about such information, the Company and the business and prospects of the Company which he deems necessary to evaluate the merits and risks related to his investment in the Stock and to verify the information contained in the information received as indicated in this Section 2(e), and he has relied solely on such information.

(f) The Management Stockholder further represents and warrants that (i) his financial condition is such that he can afford to bear the economic risk of holding the Stock for an indefinite period of time and has adequate means for providing for his current needs and personal contingencies, (ii) he can afford to suffer a complete loss of his investment in the Stock, (iii) he understands and has taken cognizance of all risk factors related to the acquisition of the Stock, (iv) his knowledge and experience in financial and business matters are such that he is capable of evaluating the merits and risks of his acquisition of the Stock as contemplated by this Agreement, and (v) his participation in the acquisition of the Purchased Stock is voluntary.

(g) The Management Stockholder hereby grants to Luxco an irrevocable proxy coupled with an interest to vote his Stock at any meeting of stockholders of the Company, to consent to holding such meetings at short notice and to exercise the voting rights attached to the Stock by way of unanimous written consent in lieu of a meeting, which proxy shall be valid and remain in effect until the earliest to occur of (i) an initial Public Offering, (ii) a Change in Control and (iii) the date on which the Investors’ beneficial ownership percentage (directly or indirectly) in the Company’s Common Stock is less than thirty-three and one-third percent (33 1/3%) of the amount of such ownership percentage as of August 22, 2006.

3. Transferability of Stock.

(a) The Management Stockholder agrees that he will not directly or indirectly, offer, transfer, sell, assign, pledge, hypothecate or otherwise dispose of (any of the foregoing acts being referred to herein as a “transfer”) any shares of Purchased Stock, at the time of exercise, the Common Stock issuable upon exercise of the Options (“Option Stock”) and any other Common Stock otherwise acquired and/or held by the Management Stockholder Entities (collectively referred to as “Stock”) at any time from and after the Effective Date; provided, however, that the Management Stockholder may transfer shares of Stock during such time pursuant to one of the following exceptions: (i) transfers permitted by clauses (x), (y) and (z) of Section 2(a) hereof; (ii) a sale of shares of Common Stock pursuant to an effective registration statement under the Act filed by the Company (excluding any registration on Form S-8, S-4 or any successor or similar form) pursuant to Section 7 hereof; or (iii) transfers permitted pursuant

4

to the Sale Participation Agreement (as defined in Section 5(b) hereof); and provided, further, that following an initial Public Offering, the Management Stockholder may transfer shares of Stock only at the time of transfer by, and on the same terms as, the Investors and on a pro rata basis with the Investors (based on the percentage of Stock actually transferred by the Investors).

(b) Notwithstanding anything in this Agreement to the contrary, if, following an initial Public Offering, the Management Stockholder’s active employment with the Company (and/or, if applicable, its subsidiaries) is terminated as a result of the Management Stockholder’s death or Permanent Disability, the Management Stockholder may transfer, without limitation under this Agreement (but subject to any applicable securities laws), all or any portion of his or her Purchased Stock on and after the expiration of any Lock-Up Period that may be applicable.

(c) If, following an initial Public Offering, the Management Stockholder is unable to transfer shares of Stock due to restrictions on transfer of the Stock other than as set forth in this Agreement or due to the provisions of Section 7(e) hereof, then the restrictions on transfer of the Stock set forth in this Agreement shall terminate such that the Management Stockholder may (i) effect a sale of Stock to the public that the Management Stockholder would have been able to sell pursuant to Section 7 hereof or pursuant to the Sale Participation Agreement at a prior time had such other restrictions on transfer of the Stock not been in effect and (ii) effect a sale of Option Stock to the public that the Management Stockholder would have been able to sell pursuant to Section 7 hereof or pursuant to the Sale Participation Agreement at a prior time had the Options through which such Option Stock was acquired been exercisable at such prior time, in each case at the time of a sale by the Investors pursuant to Section 7 hereof or pursuant to the Sale Participation Agreement.

(d) Notwithstanding anything in this Agreement to the contrary, this Section 3 shall terminate and be of no further force or effect upon the earlier to occur of (i) a Change in Control and (ii) the date on which the Investors’ beneficial ownership percentage (directly or indirectly) in the Company’s Common Stock is less than thirty-three and one-third percent (33 1/3%) of the amount of such ownership percentage as of August 22, 2006.

4. The Company’s Option to Purchase Stock and Options of Management Stockholder Upon Certain Terminations of Employment.

(a) Termination for Cause by the Company. Except as otherwise provided herein, if (i) the Management Stockholder’s active employment with the Company (and/or, if applicable, its subsidiaries) is terminated by the Company (and/or, if applicable, its subsidiaries) for Cause, (ii) the Management Stockholder breaches any of the provisions of Section 22(a) hereof, (iii) the beneficiaries of a Management Stockholder’s Trust shall include any person or entity other than the Management Stockholder, his spouse (or ex-spouse) or his lineal descendants (including adopted children) or, if at any time after any such transfer there shall be no then living spouse or lineal descendants, then to the ultimate beneficiaries of any such trust or to the estate of a deceased beneficiary or (iv) the Management Stockholder shall otherwise effect a transfer of any of the Stock other than as permitted in this Agreement (other than as may be required by applicable law or an order of a court having competent jurisdiction) after notice from the Company of such impermissible transfer and a reasonable opportunity to cure such transfer (each, a “Section 4(a) Call Event”):

(A) With respect to the Stock, the Company may purchase all or any portion of the shares of the Stock then held by the applicable Management Stockholder Entities at a per share purchase price equal to the lesser of (x) the Fair Market Value Per Share on the applicable repurchase date and (y) the Base Price (or, with respect to any Option Stock, the Option Exercise Price) (any such applicable repurchase price, the “Section 4(a) Repurchase Price”); and

Except as otherwise provided herein, if, prior to December 31, 2011, the Management Stockholder’s active employment with the Company (and/or, if applicable, its subsidiaries) is terminated by the Management Stockholder without Good Reason (a “Section 4(b) Call Event”):

(A) With respect to the Stock, the Company may purchase all or any portion of the shares of the Stock then held by the applicable Management Stockholder Entities at a per share purchase price equal to (x) the lesser of (i) the Fair Market Value Per Share on the applicable repurchase date and (ii) the Base Price (or, with respect to any Option Stock, the Option Exercise Price), if the Section 4(b) Call Event is on or prior to December 31, 2009 or (y) the Fair Market Value Per Share, if the Section 4(b) Call Event is after December 31, 2009; and

(B) With respect to the Options, the Company may purchase all or any portion of the exercisable Options held by the applicable Management Stockholder Entities for an amount equal to the product of (x) the excess, if any, of (i) the lesser of (1) the Fair Market Value Per Share and (2) the Option Exercise Price if the Section 4(b) Call Event is on or prior to December 31, 2009 or (ii) the Fair Market Value Per Share, if the Section 4(b) Call Event is after December 31, 2009, over the Option Exercise Price and (y) the number of Exercisable Option Shares, which Options shall be terminated in exchange for such payment. In the event the foregoing Option Excess Price is zero or a negative number, all outstanding exercisable Options granted to the Management Stockholder under the Option Plan shall be automatically terminated without any payment in respect thereof. In the event that the Company does not exercise the foregoing rights, all exercisable but unexercised Options shall terminate pursuant to the terms of the Stock Option Agreement.

6

(B) With respect to the Options, the Company may purchase all or any portion of the exercisable Options held by the applicable Management Stockholder Entities for an amount equal to the product of (x) the excess, if any, of the Fair Market Value Per Share over the Option Exercise Price and (y) the number of Exercisable Option Shares, which Options shall be terminated in exchange for such payment. In the event the foregoing Option Excess Price is zero or a negative number, all outstanding exercisable Options granted to the Management Stockholder under the Option Plan shall be automatically terminated without any payment in respect thereof. In the event that the Company does not exercise the foregoing rights, all exercisable but unexercised Options shall terminate pursuant to the terms of the Stock Option Agreement. All unexercisable Options held by the applicable Management Stockholder Entities shall terminate without payment immediately upon termination of employment or on such later date as may otherwise be provided in the Stock Option Agreement.

(d) Call Notice. The Company shall have a period (the “Call Period”) of sixty (60) days from the date of any Call Event (or, if later, with respect to a Section 4(a) Call Event, from the date after discovery of, and the applicable cure period for, an impermissible transfer constituting a Section 4(a) Call Event) in which to give notice in writing to the Management Stockholder of its election to exercise its rights and obligations pursuant to this Section 4 (“Call Notice”). The completion of the purchases pursuant to the foregoing shall take place at the principal office of the Company on the tenth Business Day after the giving of the Call Notice. The applicable Repurchase Price (including any payment with respect to the Options as described in this Section 4) shall be paid by delivery to the applicable Management Stockholder Entities of a certified bank check or checks in the appropriate amount payable to the order of each of the applicable Management Stockholder Entities (or by wire transfer of immediately available funds, if the Management Stockholder Entities provide to the Company wire transfer instructions) against delivery of an irrevocable power of attorney enabling the Company to cause the transfer to it of the Stock so purchased and appropriate documents canceling the Options so terminated, appropriately endorsed or executed by the applicable Management Stockholder Entities or any duly authorized representative.

(e) Delay of Call. Notwithstanding any other provision of this Section 4 to the contrary and subject to Section 8(a) hereof, if there exists and is continuing a default or an event of default on the part of the Company or any subsidiary of the Company under any loan, guarantee or other agreement under which the Company or any subsidiary of the Company has borrowed money or if a repurchase would not be permitted under, or would otherwise violate, applicable provisions of Dutch law (each such occurrence being an “Event”), the Company shall delay the repurchase of any of the Stock or the Options (pursuant to a Call Notice timely given in accordance with Section 4(d) hereof) from the applicable Management Stockholder Entities until the first Business Day which is ten (10) calendar days after all of the foregoing Events have ceased to exist (the “Repurchase Eligibility Date”); provided, however, that (i) the number of shares of Stock subject to repurchase under this Section 4 shall be that number of shares of Stock, and (ii) in the case of a repurchase pursuant to Section 4(a), 4(b) or 4(c) hereof, the number of Exercisable Option Shares for purposes of calculating the Option Excess Price payable under this Section 4 shall be the number of Exercisable Option Shares, in each case held

7

by the applicable Management Stockholder Entities at the time of delivery of (and as set forth in) a Call Notice in accordance with Section 4(d) hereof. All Options exercisable as of the date of a Call Notice, in the case of a repurchase pursuant to Section 4(a), 4(b) or 4(c) hereof, shall continue to be exercisable until the repurchase of such Options pursuant to such Call Notice, provided that to the extent that any Options are exercised after the date of such Call Notice, the number of Exercisable Option Shares for purposes of calculating the Option Excess Price shall be reduced accordingly.

(f) Calculation of Option Excess Price. For the avoidance of doubt, in any instance where the Company purchases Options as set forth in this Section 4, the applicable Option Excess Price shall be calculated in tranches based on the applicable Option Exercise Prices relative to the applicable Repurchase Price, and not on an aggregate net basis, such that the Option Excess Price of any Options having the same Option Exercise Price, where the Option Excess Price is greater than zero, shall not be netted against the Option Excess Price of any Options having a different Option Exercise Price, where the Option Excess Price is less than or equal to zero.

(g) Effect of Accounting Principles. Notwithstanding anything set forth in this Section 4 to the contrary, in the event that it is determined by the Company (in consultation with its auditors) that the provisions of this Section 4 would result in any of the Options being classified as a liability as contemplated by FASB Statement No. 123R, Share-Based Payment, including any amendments and interpretations thereto, then the following terms shall apply in lieu of the corresponding provisions in Section 4(b) and Section 4(c) providing for the purchase by the Company of exercisable Options:

With respect to any exercisable Options, upon the occurrence of the applicable event giving rise to the Section 4 Call Event, the Management Stockholder Entities may be required to by the Company to elect, in accordance with the terms of the relevant Stock Option Agreement, to receive from the Company, on one occasion, in exchange for all of the exercisable Options then held by the applicable Management Stockholder Entities, if any, a number of shares of Stock equal to the quotient of (x) the product of (A) the excess, if any, of the Fair Market Value over the Option Exercise Price and (B) the number of shares then acquirable on exercise, divided by (y) the Fair Market Value, which Options shall be terminated in exchange for such payment of shares of Stock (such shares of Stock, the “Net Settled Stock”). (In the event the foregoing Option Excess Price is zero or a negative number, all outstanding exercisable Options shall be automatically terminated without any payment in respect thereof.) Upon the occurrence of such net settlement of all exercisable Options, the Call Period shall be deemed to be the period that is 30 days following the date that is six months after the receipt by the applicable Management Stockholder Entities of the Net Settled Stock, during which time the Company may, on delivery of Call Notice, purchase all or any portion of the Net Settled Stock held by the applicable Management Stockholder Entities, at a per share price equal to the applicable Repurchase Price for Option Stock identified in Section 4(b) or Section 4(c), as applicable.

8

(h) Effect of Change in Control and Reduction in Investors’ Ownership. Notwithstanding anything in this Agreement to the contrary, this Section 4 shall terminate and be of no further force or effect upon the earlier to occur of (i) a Change in Control and (ii) the date on which the Investors’ beneficial ownership percentage (directly or indirectly) in the Company’s Common Stock is less than thirty-three and one-third percent (33 1/3%) of the amount of such ownership percentage as of August 22, 2006.

5. Adjustment of Repurchase Price; Definitions.

In determining the applicable repurchase price of the Stock and Options, as provided for in Section 4 hereof, appropriate adjustments shall be made for any stock dividends, extraordinary cash dividends, splits, combinations, recapitalizations or any other adjustment in the number of outstanding shares of Stock in order to maintain, as nearly as practicable, the intended operation of the provisions of Section 4 hereof.

(a) The Management Stockholder hereby agrees to be bound by all of the terms, conditions and obligations of the piggyback registration rights contained in the Shareholders’ Agreement (the “Shareholders’ Agreement”) to be entered into by and among Luxco, Valcon Acquisition B.V., the Company and investors party thereto (the “Piggyback Registration Rights”), in the form provided to the Management Stockholder on the date hereof (subject to any amendments thereto to which the Management Stockholder has agreed in writing to be bound), and, following the consummation of an initial Public Offering, if any one of the Investors are selling stock, shall have all of the rights and privileges of the Piggyback Registration Rights (including, without limitation, the right to participate in one or more Public Offerings and any rights to indemnification and/or contribution from the Company and/or the Investors), in each case as if the Management Stockholder were an original party (other than Luxco, Valcon Acquisition B.V. and the Company) to the Shareholders’ Agreement, subject to applicable and customary underwriter restrictions; provided, however, that at no time shall the Management Stockholder have any rights to request registration under the Shareholders’ Agreement; and provided further, that the Management Stockholder shall not be bound by any amendments to the Shareholders’ Agreement unless the Management Stockholder consents in writing thereto provided that such consent will not be unreasonably withheld. All Stock, whether acquired upon the exercise of an Option or not, acquired or held by the applicable Management Stockholder Entities pursuant to this Agreement shall be deemed to be “Listed Shares” as defined in the Shareholders’ Agreement.

(b) In the event of a sale of Common Stock by the Investors in accordance with the terms of the Shareholders’ Agreement, the Company will promptly notify the Management Stockholder in writing (a “Notice”) of any proposed registration (a “Proposed Registration”). If within five (5) Business Days of the receipt by the Management Stockholder of such Notice, the Company receives from the applicable Management Stockholder Entities a written request (a “Request”) to register shares of Stock held by the applicable Management Stockholder Entities (which Request will be irrevocable unless otherwise mutually agreed to in writing by the Management Stockholder and the Company), shares of Stock will be so registered as provided in this Section 7; provided, however, that for each such registration statement only one Request, which shall be executed by the applicable Management Stockholder Entities, may be submitted for all Listed Shares held by the applicable Management 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 Management Stockholder Entities, including all shares of Stock which the Management Stockholder Entities are then entitled to acquire under an unexercised Option to the extent then exercisable, multiplied by a fraction, the numerator of which is the number of shares of Stock being sold by the Investors and any affiliated or unaffiliated investment partnerships and investment limited liability companies investing with the Investors and the denominator of which is the aggregate number of shares of Stock owned by the Investors and any investment partnerships and investment limited liability companies investing with the Investors or (ii) the maximum number of shares of Stock which the Company can register in the Proposed Registration without adverse

15

effect on the offering in the view of the managing underwriters (reduced pro rata as more fully described in subsections (d) and (e) of this Section 7) or (iii) the maximum number of shares which the Management Stockholder (pro rata based upon the aggregate number of shares of Stock the Management Stockholder and all Other Management Stockholders have requested to be registered) is permitted to register under the Piggyback Registration Rights.

(d) Subject to subsection (e) of this Section 7, 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 the Proposed 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 Management Stockholder and all Other Management 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 all exercisable 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) 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 by the Management Stockholder and all Other Management Stockholders would 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, in addition to shares to be sold by the Company and the selling Investors, the number of shares of Stock requested to be sold by the Management Stockholder and all Other Management Stockholders which, in the opinion of such managing underwriter, can be sold without having the adverse effect referred to above, such amount to be allocated pro rata among all requesting parties on the basis of the relative number of shares of Stock then held by each such party (including upon exercise of all exercisable Options) (provided that any shares thereby allocated to any such party that exceed such party’s request will be reallocated among the remaining requesting parties in like manner).

(f) Upon delivering a Request, the Management Stockholder will, if requested by the Company, execute and deliver a custody agreement and power of attorney having customary terms and in form and substance satisfactory to the Company with respect to the shares of Stock to be registered pursuant to this Section 7 (a “Custody Agreement and Power of Attorney”). The Custody Agreement and Power of Attorney will provide, among other things, that the Management Stockholder will irrevocably appoint said custodian and attorney-in-fact as the Management Stockholder’s agent and attorney-in-fact with full power and authority to act under the Custody Agreement and Power of Attorney on the Management Stockholder’s behalf with respect to the matters specified therein.

16

(g) If the number of shares of Stock that the Management Stockholder is permitted to include in a Request pursuant to this Section 7 is limited by the fact that the Options are not exercisable at the time of such Proposed Registration, then at such time as the Options become exercisable (in whole or in part) and at any time thereafter, the Management Stockholder shall be entitled to register for public sale as part of any subsequent Proposed Registration such additional number of shares of Stock as the Management Stockholder could have registered at the time of the initial Proposed Registration.

(h) The Management Stockholder agrees that he will execute such other agreements as the Company may reasonably request to further evidence the provisions of this Section 7.

8. Pro Rata Repurchases; Dividends.

(a) Notwithstanding anything to the contrary contained in Section 4 hereof, if at any time consummation of any purchase or payment to be made by the Company pursuant to this Agreement and the Other Management Stockholders Agreements would result in an Event, then the Company shall make purchases from, and payments to, the Management Stockholder and Other Management Stockholders pro rata (on the basis of the proportion of the number of shares of Stock each such Management Stockholder and all Other Management 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”). The provisions of Section 4(e) hereof shall apply in their entirety to payments and repurchases with respect to shares of Stock which may not be made due to the limits imposed by the Maximum Repurchase Amount under this Section 8(a). Until all of such Stock is purchased and paid for by the Company, the Management Stockholder and the Other Management Stockholders whose Stock is not purchased in accordance with this Section 8(a) shall have priority, on a pro rata basis, over other purchases of Stock by the Company pursuant to this Agreement and Other Management Stockholders’ Agreements.

(b) In the event any dividends are paid with respect to the Stock, the Management Stockholder will be treated in the same manner as all other holders of Common Stock with respect to shares of Stock then owned by the Management Stockholder, and, with respect to any Options held by the Management Stockholder, in accordance, as applicable, with the Stock Option Agreement.

9. Rights to Negotiate Repurchase Price. 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 Management Stockholder, at any time, upon such terms and conditions, and for such price, as may be mutually agreed upon in writing between the Parties hereto, 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 Management 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.

17

13. Management Stockholder’s Employment by the Company. Nothing contained in this Agreement or in any other agreement entered into by the Company and the Management Stockholder contemporaneously with the execution of this Agreement (subject to, and except as set forth in, the applicable provisions of any offer letter or letter of employment provided to the Management Stockholder by the Company or any employment agreement entered by and between the Management Stockholder and the Company) (i) obligates the Company or any subsidiary of the Company to employ the Management Stockholder in any capacity whatsoever or (ii) prohibits or restricts the Company (or any such subsidiary) from terminating the employment of the Management Stockholder at any time or for any reason whatsoever, with or without Cause, and the Management Stockholder hereby acknowledges and agrees that neither the Company nor any other person has made any representations or promises whatsoever to the Management Stockholder concerning the Management Stockholder’s employment or continued employment by the Company or any subsidiary of the Company.

22. Confidential Information; Covenant Not to Compete.

(a) In consideration of the Company entering into this Agreement with the Management Stockholder, the Management Stockholder hereby agrees effective as of the date of the Management Stockholder’s commencement of employment with the Company or its Subsidiaries, without the Company’s prior written consent, the Management Stockholder shall not, directly or indirectly, (i) at any time during or after the Management Stockholder’s employment with the Company or its Subsidiaries, disclose any Confidential Information pertaining to the business of the Company, the Investors, or any of their respective Rule 405 Affiliates (except when required to perform his or her duties to the Company or one of its Subsidiaries, by law or judicial process) or disparage the Company, the Investors, or any of their respective Rule 405 Affiliates; or (ii) at any time during the Management Stockholder’s employment with the Company or its Subsidiaries and for a period of twelve (12) months thereafter, directly or indirectly (A) act as a proprietor, investor, director, officer, employee, substantial stockholder, consultant, or partner in any business that directly or indirectly competes with the business of the Company, the Investors, or any of their respective Rule 405 Affiliates, (B) solicit customers or clients of the Company or any of its Subsidiaries to terminate their relationship with the Company or any of its Subsidiaries or otherwise solicit such customers or clients to compete with any business of the Company, the Investors, or any of their respective Rule 405 Affiliates or (C) solicit or offer employment to any person who has been employed by the Company or any of its Subsidiaries at any time during the twelve (12) months immediately preceding the termination of the Management Stockholder’s employment; provided, however, that the foregoing clause (ii) shall not apply with respect to any Rule 405 Affiliates that are engaged in a business substantially different than that of the Company or any of its Subsidiaries. If the Management Stockholder is bound by any other agreement with the Company regarding the use or disclosure of confidential information, the provisions of this Agreement shall be read in such a way as to further restrict and not to permit any more extensive use or disclosure of confidential information.

(b) Notwithstanding clause (a) above, if at any time a court holds that the restrictions stated in such clause (a) are unreasonable or otherwise unenforceable under circumstances then existing, the Parties hereto agree that the maximum period, scope or geographic area determined to be reasonable under such circumstances by such court will be

21

substituted for the stated period, scope or area. Because the Management Stockholder’s services are unique and because the Management Stockholder has had access to Confidential Information, the Parties hereto agree that money damages will be an inadequate remedy for any breach of this Agreement. In the event of a breach or threatened breach of this Agreement, the Company or its successors or assigns may, in addition to other rights and remedies existing in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive relief in order to enforce, or prevent any violations of, the provisions hereof (without the posting of a bond or other security).

(c) In the event that the Management Stockholder breaches any of the provisions of Section 22(a) hereof, in addition to all other remedies that may be available to the Company, such Management Stockholder shall be required to pay to the Company any amounts actually paid to him or her by the Company in respect of any repurchase by the Company of the Options or shares of Common Stock underlying the Options held by such Management Stockholder.
