(a) If an Employee’s employment Terminates for any reason, irrespective of whether such Employee receives, in connection with such Termination, any severance or other payment from the Company or any of its Affiliates under any employment agreement or otherwise, the Company shall have the right, at its option, exercisable by delivery of written notice to such Employee during the Call Period, to purchase all or any portion of the shares of Capital Stock held by such Employee as of the date of such Termination or acquired after the date of Termination upon exercise of any stock options held by such Employee.

(b) If an Employee’s employment Terminates for any reason other than a Termination by the Company or one of its subsidiaries for Cause or a Termination by the Employee prior to the second anniversary of the Recapitalization Closing Date without Good Reason, or if an Employee’s employment Terminates by reason of the Employee’s death, permanent disability or adjudicated incompetency, the purchase price per share of any shares of Capital Stock purchased pursuant to Section 3.2(a) shall be equal to the Fair Market Value of such share of Capital Stock as of the date that such Employee’s employment Terminates.

(c) If an Employee’s employment is Terminated by the Company or one of its subsidiaries for Cause, the purchase price per share of any shares of Capital Stock purchased pursuant to Section 3.2(a) shall be equal to the lesser of (i) ninety percent (90%) of the Shareholder’s Cost and (ii) the Fair Market Value of such share of Capital Stock as of the date that such Employee’s employment Terminates.

(d) If an Employee’s employment is Terminated by the Employee prior to the second anniversary of the Recapitalization Closing Date without Good Reason, the purchase price per share of any shares of Capital Stock purchased pursuant to Section 3.2(a) shall be equal to the lesser of (i) the Shareholder’s Cost and (ii) the Fair Market Value of such share of Capital Stock as of the date that such Employee’s employment Terminates.

(e) All shares of Capital Stock held by any Employee after such Employee’s employment Terminates that the Company does not purchase pursuant to the provisions of Section 3.2(a) shall continue to be subject to the provisions of this Agreement (including Sections 3.3, 3.4 and 3.5 and Section 4).

(f) Subject to Section 3.2(g), the closing (the “Closing”) of any purchase of shares of Capital Stock which the Company has elected to purchase pursuant to Section 3.2(a) (the “Called Shares”) shall take place at the principal office of the Company on the later of (i) fifteen business days after the Notice Date and (ii) if the Employee’s employment Terminates by reason of death, permanent disability or adjudicated incompetency, ten days after the appointment of a Legal Representative (or, in each case, if such day is not a business day, then the first business day thereafter) (such later date, the “Scheduled Closing Date”). At the Closing, the Employee shall sell, convey, transfer, assign and deliver to the Company all right, title and interest in and to the Called Shares, which shall constitute (and, at the Closing, such Employee shall represent, warrant and certify the same to the Company in writing) good and unencumbered title to such shares, free and clear of all liens, security interests, encumbrances and adverse claims of any kind and nature (other than those in favor of the Company and the NMP Entities pursuant to this Agreement), and shall deliver to the Company a certificate representing the shares duly endorsed for transfer, or accompanied by appropriate stock transfer powers duly executed, and with all necessary transfer tax stamps affixed thereto at the expense of such Employee, and the Company shall deliver to such Employee, in full payment of the purchase price for the Called Shares, either a wire transfer to an account designated by such Employee or a cashier’s, certified or official bank check payable to the order of such Employee (the method of payment to be at the option of the Company), in an amount equal to the Call Price multiplied by the aggregate number of Called Shares. Notwithstanding anything herein to the contrary, from and after the Notice Date, such Employee shall not have any rights with respect to any of the Called Shares (including any rights pursuant to Sections 3.3(a) and 3.4), except to receive the purchase price therefor.

(g) Notwithstanding the provisions of Section 3.2(f), if the Company exercises its option to purchase Called Shares, but the Company is prohibited from effecting the Closing on the Scheduled Closing Date by any contractual obligation of the Company or any of its Affiliates, the terms of any capital stock or by applicable law (collectively, “Prohibitions”), then the Closing shall take place on the first practicable date on which no Prohibitions are applicable,

and, at the Closing, the Company shall pay to such Employee interest on the unpaid purchase price from and including the Scheduled Closing Date to, but not including, the date of the Closing, at the Prime Rate. If at any time the Prohibitions shall cease to be applicable to any portion of the Called Shares not purchased, then the Company shall purchase such portion on the first practicable date on which the Company is permitted to do so.

(h) Notwithstanding anything to the contrary contained in this Section 3.2, if at any time prior to any Closing under this Section 3.2 the Company shall become entitled pursuant to Section 4.2 to purchase any shares of Capital Stock then held by an Employee, the Company, at its option, shall be relieved of all of its obligations under Section 3.2 with respect to the purchase of any Called Shares and the Company’s obligations with respect to the purchase of such shares of Capital Stock shall be governed by Section 4.2.

(i) If, on the date the Employee’s employment Terminates, shares of capital stock of the same class as those held by the Employee are listed or traded in a manner referred to in the definition of “Closing Price”, then the Fair Market Value per share of such Employee’s Capital Stock shall equal the average of the daily Closing Prices of such capital stock on the twenty consecutive trading days immediately preceding such date; otherwise, the Fair Market Value per share of such Employee’s Capital Stock shall be the per share fair market value of such Capital Stock as determined in good faith by the Board, and such determination shall be final and binding on the Company and the Employee.

(a) Participation in Sales of Capital Stock. Each Shareholder, at such Shareholder’s option, may participate proportionately (as provided for below), and the NMP Entities shall allow each Shareholder to participate, in any sale (other than a Public Offering or pursuant to Rule 144, which shall be governed by Section 3.4) of all or a portion of the Capital Stock owned by any of the NMP Entities to any Third Party. The Company shall notify each Shareholder in writing of the NMP Entities’ intention to effect such a sale to a Third Party, the identity of the Third Party and the nature and per share amount of consideration to be paid by the Third Party, at least ten days before the closing of any such proposed sale. The NMP Entities shall provide such information to the Company as promptly as practicable to enable the Company to comply with the foregoing sentence. Any sale of shares of Capital Stock by any Shareholder pursuant to this Section 3.3(a) shall be for the same consideration per share, on substantially the same terms and subject to substantially the same conditions as the sale of shares of Capital Stock owned by the NMP Entities; provided, that the consideration per share, terms and conditions shall be adjusted as necessary to the extent such Shareholder and the NMP Entities are selling different types of Capital Stock; and provided, further, that there shall be no adjustment in the consideration per share in the event that the NMP Entities are also selling shares of Series A Preferred Stock. Each Shareholder will be entitled to sell the same percentage of its Capital Stock as the NMP Entities sell of their Capital Stock in such sale (determined on the basis of the aggregate number of shares of Common Stock owned and the aggregate number of such shares of Common Stock being sold by the NMP Entities (assuming conversion, exchange or exercise of all Convertible Securities held by the NMP Entities and such Shareholder)). If a Shareholder sells any shares of Capital Stock pursuant to this Section 3.3(a), such Shareholder shall pay and

be responsible for such Shareholder’s proportionate share of the Expenses of Sale and the Sale Obligations.

(b) Participation in Sales of Debentures. Kenneth E. deLaski, at his option, may participate proportionately (as provided for below), and the NMP Entities shall allow Mr. deLaski to participate, in any sale of all or a portion of the Debentures owned by any of the NMP Entities to any Third Party. The Company shall notify Mr. deLaski in writing of the NMP Entities’ intention to effect such a sale to a Third Party, the identity of the Third Party and the nature and per share amount of consideration to be paid by the Third Party, at least ten days before the closing of any such proposed sale. The NMP Entities shall provide such information to the Company as promptly as practicable to enable the Company to comply with the foregoing sentence. Any sale of Debentures by Mr. deLaski pursuant to this Section 3.3(b) shall be for the same price, on substantially the same terms and subject to substantially the same conditions as the sale of Debentures owned by the NMP Entities. Mr. deLaski will be entitled to sell the same percentage of his Debentures as the NMP Entities sell of their Debentures in such sale (determined on the basis of the aggregate principal amount of Debentures owned and the aggregate principal amount of Debentures being sold by the NMP Entities). If Mr. deLaski sells any Debentures pursuant to this Section 3.3(b), Mr. deLaski shall pay and be responsible for his proportionate share of the Expenses of Sale and the Sale Obligations.

(a) If the NMP Entities propose to sell all or any portion of the shares of Common Stock owned by the NMP Entities in a Public Offering in connection with the exercise of their registration rights under the Investor Rights Agreement, each Shareholder shall be entitled to participate proportionately in such Public Offering by selling in the Public Offering the same percentage of such Shareholder’s shares of Common Stock as the NMP Entities sell of their shares of Common Stock in the Public Offering (determined on the basis of the aggregate number of shares of Common Stock owned and the aggregate number of such shares of Common Stock being sold by the NMP Entities (assuming conversion, exchange or exercise of all Convertible Securities held by the NMP Entities and such Shareholder)). The Company shall notify each Shareholder in writing of the NMP Entities’ intention to effect such Public Offering at least ten business days, or such shorter time as the Company deems practicable, before the effective date of the registration statement relating to such Public Offering (the “Section 3.4 Notice”) and shall cause such Shareholder’s shares to be sold in such Public Offering to be included therein. If the Shareholder wishes to participate in such Public Offering, such Shareholder shall notify the Company in writing within three business days after receipt of the Section 3.4 Notice of such Shareholder’s intention to participate in such Public Offering, including the number of shares with respect to which such Shareholder will so participate. Any failure by a Shareholder to so notify the Company within such three business-day period shall be deemed an election by such Shareholder not to participate in such Public Offering with respect to any of such Shareholder’s shares. If any Shareholder sells any shares pursuant to this Section 3.4, such Shareholder shall pay and be responsible for such Shareholder’s proportionate share of the Expenses of Sale and the Sale Obligations, including indemnifying the underwriters of such Public Offering, on a proportionate basis, to the same extent as the NMP Entities are required to indemnify such underwriters. If any Shareholder sells any shares pursuant to this Section 3.4,

such Shareholder shall be entitled to all of the rights and be bound by all of the obligations of a “Participating Holder” under Sections 2.1(g), 2.3(a)(iii), 2.3(a)(vi), 2.3(a)(viii)(to the extent such section relates to the provision of an earnings statement), 2.3(a)(xix), 2.3(a)(xx), the last two sentences of Section 2.4(a) and Sections 2.4(b) and 2.6 of the Investor Rights Agreement, and shall be entitled to all of the rights and be bound by all of the obligations of a “Holder” under Sections 2.2(b), 2.3(c), 2.6 and 2.8 of the Investor Rights Agreement.

(b) In connection with any proposed Public Offering of securities of the Company, whether by any of the NMP Entities or the Company or otherwise, and whether or not such Shareholder is participating therein, each Shareholder agrees (i) to supply any information reasonably requested by the Company in connection with the preparation of a registration statement and/or any other documents relating to such Public Offering, (ii) to execute and deliver any agreements and instruments reasonably requested by the Company to effectuate such Public Offering, including an underwriting agreement, a custody agreement and a “hold back” agreement pursuant to which the Shareholder will agree not to sell or purchase any securities of the Company (whether or not such securities are otherwise governed by this Agreement) for the same period of time following the Public Offering as is agreed to by the NMP Entities with respect to themselves and (iii) to otherwise comply with the provisions of Section 2 of the Investor Rights Agreement applicable to the Participating Holders (as defined therein). If the Company requests that the Shareholder take any of the actions referred to in clause (i), (ii) or (iii) of the previous sentence, the Shareholder shall take such action promptly but in any event within five days following the date of such request.

(c) If the NMP Entities sell all or any portion of the shares of Common Stock owned by the NMP Entities in a transaction effected under Rule 144, the NMP Entities shall give written notice to the Company (the “Rule 144 Notice”) within five business days following such sale, with such notice stating the date of such sale and the percentage of shares sold by the NMP Entities and the Company shall promptly notify each Shareholder of such Rule 144 Notice. For a period of 30 days after the date of the Rule 144 Notice, each Shareholder shall be entitled to sell, in a transaction effected under Rule 144 (if the sale by such Shareholder otherwise meets the requirements of Rule 144), the same percentage of such Shareholder’s shares of Common Stock as the NMP Entities have sold of their shares of Common Stock in the transaction effected under Rule 144 (determined on the basis of the aggregate number of shares of Common Stock owned and the aggregate number of such shares of Common Stock being sold by the NMP Entities (assuming conversion, exchange or exercise of all Convertible Securities held by the NMP Entities and such Shareholder)).

3.5 Required Participation in Sale of Securities by the NMP Entities. Notwithstanding any other provision of this Agreement to the contrary, if the NMP Entities shall propose to sell (including by exchange, in a business combination or otherwise) all or any portion of their shares of Capital Stock or Debentures in a bona fide arm’s-length transaction, or the Company proposes to sell or otherwise transfer for value all or substantially all of the stock, assets or business (whether by merger, sale or otherwise) of the Company, (i) the NMP Entities, at their option, may require, in the case of a sale of Capital Stock or Debentures by the NMP Entities, that each Shareholder sell a proportionate amount of such Shareholder’s shares of Capital Stock or Debentures (determined on the same basis described in Section 3.3), as applicable, and waive any

appraisal right that they may have in connection with the Transaction and, (ii) in any case, if shareholder approval of the Transaction is required and the Company’s shareholders are entitled to vote thereon, each Shareholder shall vote all of such Shareholder’s shares of Capital Stock in favor of such Transaction. Any sale of shares of Capital Stock or Debentures, as applicable, by a Shareholder pursuant to this Section 3.5 shall be for the same consideration per share, on substantially the same terms and subject to substantially the same conditions as the sale of shares of Capital Stock or Debentures, as applicable, owned by the NMP Entities; provided, that the consideration per share, terms and conditions shall be adjusted as necessary to the extent such Shareholder and the NMP Entities are selling different types of Capital Stock; and provided, further, that there shall be no adjustment in the consideration per share in the event that the NMP Entities are also selling shares of Series A Preferred Stock. If any Shareholder sells any shares of Common Stock or Debentures, as applicable, pursuant to this Section 3.5, such Shareholder shall pay and be responsible for such Shareholder’s proportionate share of the Expenses of Sale and the Sale Obligations.

3.6 Option to Pay Cash. Notwithstanding anything contained to the contrary in Section 3.3 or 3.5, in connection with a sale by the NMP Entities pursuant to Section 3.3 or 3.5 where the consideration in such sale consists of or includes securities, if the sale of such securities to the Shareholder would require either a registration statement under the Securities Act of 1933, as amended, or preparation of a disclosure statement pursuant to Regulation D (or any successor regulation) under the Securities Act of 1933, as amended, or a similar provision of any state securities law, and such registration statement or disclosure statement is not otherwise being prepared in connection with the sale, then, at the option of the NMP Entities, the Shareholder may receive, in lieu of such securities, the fair market value of such securities in cash, as determined in good faith by the Board, whose determination shall be final and binding.

4.1 Prohibition Against Certain Activities. Each Shareholder agrees that such Shareholder will not at any time (a) disclose or furnish to any other Person or use for such Shareholder’s own or any other Person’s account any Confidential or Proprietary Information (other than in the course of such Shareholder’s employment with the Company, if such Shareholder is an employee of the Company) except for Permitted Disclosures (a “Prohibited Disclosure”), (b) directly or indirectly solicit for employment, including without limitation, recommending to any subsequent employer the solicitation for employment of, any employee of the Company or any Affiliate thereof (provided, that this clause (b) shall expire on the second anniversary of the Relevant Date) (a “Prohibited Solicitation”) and (c) commit a breach of the provisions of Section 3.1 (a “Prohibited Transfer”).

4.2 Right to Purchase Shares. Each Shareholder understands and agrees that the Company has provided for such Shareholder to hold shares of Capital Stock in the Company to reward such Shareholder for such Shareholder’s future efforts and loyalty to the Company and its Affiliates by giving such Shareholder the opportunity to participate in the potential future appreciation of the Company. Accordingly, if (a) such Shareholder engages in any Prohibited Disclosure or breaches or violates such Shareholder’s obligations relating to the non-disclosure

or non-use of confidential or proprietary information under any Non-Competition Agreement or Employee Agreement to which such Shareholder is a party, or (b) such Shareholder engages in any Prohibited Solicitation or breaches or violates any non-solicitation obligations under any Non-Competition Agreement or Employee Agreement to which such Shareholder is a party, or (c) such Shareholder engages in any Prohibited Transfer, or (d) such Shareholder engages (at any time prior to the second anniversary of the Relevant Date) in any Competitive Activity or breaches or violates any non-competition obligations under any Non-Competition Agreement or Employee Agreement to which such Shareholder is a party, or (e) such Shareholder is convicted of a felony against the Company or any of its Affiliates, then, in addition to any other rights and remedies available to the Company, the Company shall be entitled, at its option, exercisable by written notice (the “Repurchase Notice”) to such Shareholder, to purchase all or any portion of the shares of Capital Stock then held by such Shareholder. Notwithstanding the foregoing (but without limiting any other rights and remedies available to the Company), the Company shall not be entitled to purchase all or any portion of the shares of Capital Stock of any Shareholder pursuant to this Section 4 with respect to a breach of:

(i) clause (a) of this Section 4.2 by reason of such Shareholder’s having disclosed Confidential or Proprietary Information, if the disclosure was not made in bad faith, such disclosure does not have a significant adverse impact on the Company and such Shareholder uses its reasonable best efforts to minimize any adverse impact on the Company resulting from such disclosure;

(ii) clause (c) of this Section 4.2, if such Shareholder believed in good faith at the time of Transfer that the Transfer was permitted under Section 3.1 and the breach of Section 3.1 is cured promptly (and in any event within 30 days) after written notice thereof is provided to such Shareholder; or

(iii) clause (d) of this Section 4.2, if such Shareholder acted in good faith, was unaware, after due inquiry, that such activity constituted a Competitive Activity or a breach or violation of any non-competition obligations under any Non-Competition Agreement or Employee Agreement to which such Shareholder is a party, and ceases all activities that constitute a Competitive Activity or such breach or violation promptly (and in any event within 30 days) after such Shareholder becomes aware that such activity constitutes a Competitive Activity or such breach or violation.

4.3 Purchase Price; Closing. The purchase price per share of the shares of Capital Stock purchased pursuant to this Section 4 (the “Section 4.3 Called Shares”) shall be equal to the lesser of (i) ninety percent (90%) of the Shareholder’s Cost and (ii) the Fair Market Value of such share on the business day immediately preceding the date of repurchase (the lesser of (i) and (ii), the “Section 4.3 Call Price”). The closing of a purchase pursuant to this Section 4.3 shall take place at the principal office of the Company ten days following the date of the Repurchase Notice (and if such tenth day is not a business day, then the first business day thereafter), except that if the Company is prohibited from repurchasing any Section 4.3 Called Shares by any Prohibitions, the closing of such purchase shall take place on the first practicable date on which the Company is permitted to purchase such Section 4.3 Called Shares but no interest shall be paid to such Shareholder on the Section 4.3 Call Price during such period. If at

any time the Prohibitions shall cease to be applicable to any portion of the Section 4.3 Called Shares not purchased, then the Company shall purchase such portion on the first practicable date on which the Company is permitted to do so. At such closing, such Shareholder shall sell, convey, transfer, assign and deliver to the Company all right, title and interest in and to the Section 4.3 Called Shares, which shall constitute (and, at the closing, such Shareholder shall represent, warrant and certify the same to the Company in writing) good and unencumbered title to such shares, free and clear of all liens, security interests, encumbrances and adverse claims of any kind and nature (other than those in favor of the Company and the NMP Entities pursuant to this Agreement), and shall deliver to the Company a certificate representing the shares duly endorsed for transfer, or accompanied by appropriate stock transfer powers duly executed, and with all necessary transfer tax stamps affixed thereto at the expense of such Shareholder, and the Company shall deliver to such Shareholder, in full payment of the Section 4.3 Call Price payable for each Section 4.3 Called Share, a check payable to the order of such Shareholder, in an amount equal to the Section 4.3 Call Price multiplied by the aggregate number of Section 4.3 Called Shares. Notwithstanding anything herein to the contrary, from and after the date of the Repurchase Notice, such Shareholder shall not have any rights with respect to any of the Section 4.3 Called Shares (including any rights pursuant to Section 3.3(a) or 3.4), except to receive the purchase price therefor.

4.4 Purchase in Connection with a Transaction. Notwithstanding anything to the contrary set forth in Sections 3.3, 3.4 or 3.5, if at the time of a Transaction in which a Shareholder is participating, the Company is entitled to purchase such Shareholder’s shares of Common Stock pursuant to this Section 4, and if the Section 4.3 Call Price would be less than the proceeds per share to such Shareholder from such Transaction, then such Shareholder shall be entitled to receive for each share of Common Stock only the Section 4.3 Call Price, with the balance of the proceeds of sale in the Transaction being remitted to the other shareholders of the Company participating in such Transaction pro rata in accordance with their respective participation in such Transaction.

5.1 Termination of Restrictions and Rights. Notwithstanding any other provision of this Agreement to the contrary, but subject to the restrictions of all applicable federal and state securities laws, including the restrictions in this Agreement relating thereto, from and after the Release Date (i) any and all shares of Capital Stock owned by the Shareholders may be sold, transferred, assigned, exchanged, pledged, encumbered or otherwise disposed of (and the Shareholders may grant any option or right to purchase such shares or any legal or beneficial interest therein, or may continue to hold such shares), free of the restrictions contained in this Agreement and (ii) the Shareholders shall no longer be entitled to any of the rights contained in this Agreement, except those rights set forth in Section 3.3(b), which shall continue so long as any Debentures are outstanding, and those rights set forth in Section 3.4, which shall continue until the NMP Entities no longer hold any shares of Capital Stock. Without limiting the generality of the foregoing, from and after the Release Date, the provisions of Sections 3 (other than Sections 3.3(b) and 3.4) and 4 shall terminate and have no further force or effect.

5.2 Distribution. Notwithstanding any other provision of this Agreement to the contrary, but subject to the restrictions of all applicable federal and state securities laws, including the restrictions in this Agreement relating thereto, if the NMP Entities shall distribute all or any portion of the shares of Common Stock owned by the NMP Entities to their limited partners in a pro rata distribution (based upon the limited partners’ relative partnership interests) made to all of their limited partners (“Distribute” or a “Distribution”), then the Shareholders shall be released from all obligations and restrictions, and shall no longer be entitled to any of the rights, contained in this Agreement, including those arising under Sections 3 and 4, with respect to the percentage of the Shareholder’s shares of Common Stock as the NMP Entities have Distributed determined on the basis of the aggregate number of shares of Common Stock owned and the aggregate number of such shares of Common Stock being Distributed by the NMP Entities (assuming conversion, exchange or exercise of all Convertible Securities held by the NMP Entities)) (the “Released Shares”). The NMP Entities shall notify the Shareholders in writing of any Distribution no later than 30 days after any such Distribution.

6.1 Distributions. In the event of any dividend, distribution or exchange paid or made in respect of the Common Stock consisting of Affiliate Securities, (a) the restrictions and rights with respect to the Common Stock that are contained in this Agreement shall be applicable to the Affiliate Securities without further action of the parties (with the references to Common Stock being deemed references to the Affiliate Securities and the references to the Company being deemed references to the Affiliate), and (b) as a condition precedent to the receipt of the Affiliate Securities by a Shareholder, such Shareholder shall enter into a shareholders’ agreement containing terms substantially equivalent to those contained herein with respect to the Affiliate Securities (but reflecting the economics of the dividend, distribution or exchange and the capitalization of the Affiliate). The Board, in good faith, shall determine such terms and its determination shall be final and binding on such Shareholder.

6.2 Further Assurances. Each party hereto shall cooperate with each other party, shall do and perform or cause to be done and performed all further acts and things, and shall execute and deliver all other agreements, certificates, instruments, and documents as any other party hereto reasonably may request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

Notwithstanding anything contained in this Agreement to the contrary, each Shareholder hereby acknowledges and agrees that no Shareholder shall have any right to enforce this Agreement against any other Shareholder or compel or seek to compel the Company or any of the NMP Entities to enforce this Agreement against any other Shareholder, and such right to enforce this Agreement against any Shareholder shall be solely and exclusively vested in the Company and the NMP Entities (and their respective successors and assigns). Without limiting the generality of the foregoing, each Shareholder hereby acknowledges and agrees that the Company and the NMP Entities (and their respective successors and assigns) shall have the sole and exclusive right to waive any rights of the Company and the NMP Entities hereunder and compliance by any Shareholder with any provision hereof and to provide any Shareholder with terms that are different from (including, without limitation, terms that are more favorable or less favorable than) the terms provided in this Agreement to any other Shareholder.

6.9 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all such counterparts shall together constitute one and the same instrument.

6.10 Entire Agreement. This Agreement, each Non-Competition Agreement, each Employee Agreement, the Investor Rights Agreement and the Recapitalization Agreement, and any other agreement referenced herein constitute the entire agreement, and supersede all prior agreements and understandings, oral and written, between the parties hereto with respect to the subject matter hereof.

6.11 Withholding. The Company shall have the right to deduct from any amount payable under this Agreement any taxes or other amounts required by applicable law to be withheld. Each Shareholder agrees to indemnify the Company against any federal, state and local withholding taxes for which the Company may be liable in connection with such Shareholder’s acquisition, ownership or disposition of any Capital Stock.

6.12 No Right to Continued Employment. This Agreement shall not confer upon any Shareholder any right with respect employment by the Company or any Affiliate thereof, nor shall it interfere in any way with the right of the Company or any Affiliate thereof to terminate such Shareholder’s employment at any time.

6.13 Defaults. A default by any party to this Agreement in such party’s compliance with any of the conditions or covenants hereof or performance of any of the obligations of such party hereunder shall not constitute a default by any other party.

(a) In order to provide for the safekeeping of the certificates representing the shares of Capital Stock held by the Shareholders pursuant hereto and to facilitate the enforcement of the terms and conditions hereof, at any time requested by the Company or the NMP Entities (i) each Shareholder shall redeliver to the Company, and the Company shall retain physical possession of, all certificates representing shares of Capital Stock held by such Shareholder pursuant hereto and (ii) each Shareholder shall deliver to the Company an undated stock power, duly executed in blank, for each such certificate. Each Shareholder shall be relieved of any obligation otherwise imposed by this Agreement to deliver certificates representing shares of Capital Stock if the same are in the custody of the Company. After the Release Date, upon written request by a Shareholder therefor, the Company shall deliver to such Shareholder any certificates in its custody representing such Shareholder’s shares of Capital Stock and return or destroy any stock powers executed by such Shareholder with respect to such certificates (any such destruction to be certified by an officer of the Company).

(b) Each Shareholder hereby irrevocably appoints the NMP Entities, and each of them (individually and collectively, the “Representative”), the Shareholder’s true and lawful agent and attorney-in-fact, with full powers of substitution, to act in the Shareholder’s name, place and stead, to do or refrain from doing all such acts and things, and to execute and deliver all such documents, as the Representative shall deem necessary or appropriate in connection with a public offering of securities of the Company, including pursuant to Section 3.4, or a sale pursuant to Section 3.2, 3.3, 3.5 or 4.2, including, without in any way limiting the generality of the foregoing, in the case of a sale pursuant to Section 3.3 or 3.5, to execute and deliver on behalf of such Shareholder a purchase and sale agreement and any other agreements and documents that

the Representative deems necessary in connection with any such sale, and in the case of a public offering, to execute and deliver on behalf of such Shareholder an underwriting agreement, a “hold back” agreement, a custody agreement, a power of attorney and any other agreements and documents that the Representative deems necessary in connection with any such public offering, and in the case of any sale pursuant to Section 3.3 or 3.5 and any public offering pursuant to Section 3.4(a), to receive on behalf of such Shareholder the proceeds of the sale or public offering of the such Shareholder’s shares, to hold back from any such proceeds any amount that the Representative deems necessary to reserve against such Shareholder’s share of any Expenses of Sale and Sale Obligations and to pay such Expenses of Sale and Sale Obligations. Such Shareholder hereby ratifies and confirms all that the Representative shall do or cause to be done by virtue of its appointment as such Shareholder’s agent and attorney-in-fact. In acting for such Shareholder pursuant to the appointment set forth in this Section 6.14(b), the Representative shall not be responsible to such Shareholder for any loss or damage such Shareholder may suffer by reason of the performance by the Representative of its duties under this Agreement, except for loss or damage arising from willful violation of law or gross negligence by the Representative in the performance of its duties hereunder. The appointment of the Representative shall be deemed coupled with an interest and as such shall be irrevocable and shall survive the death, incompetency, mental illness or insanity of such Shareholder, and any person dealing with the Representative may conclusively and absolutely rely, without inquiry, upon any act of the Representative as the act of such Shareholder in all matters referred to in this Section 6.14(b).

6.15 General Interpretive Principles. Whenever used in this Agreement, except as otherwise expressly provided or unless the context otherwise requires, any noun or pronoun shall be deemed to include the plural as well as the singular and to cover all genders. The headings of the sections, paragraphs, subparagraphs, clauses and subclauses of this Agreement are for convenience of reference only and shall not in any way affect the meaning or interpretation of any of the provisions hereof. Unless otherwise specified, the terms “hereof,” “herein” and similar terms refer to this Agreement as a whole (including the exhibits, schedules and disclosure statements hereto), and references herein to Sections refer to Sections of this Agreement. Words of inclusion shall not be construed as terms of limitation herein, so that references to “include,” “includes” and “including” shall not be limiting and shall be regarded as references to non-exclusive and non-characterizing illustrations.

6.16 Disclosure of Confidential or Proprietary Information. Each Shareholder agrees that, if such Shareholder shall be required by legal process or by law to divulge any Confidential or Proprietary Information, such Shareholder shall provide the Company with prompt written notice of each request so that the Company may seek an appropriate protective order or other appropriate remedy, and such Shareholder shall cooperate with the Company to obtain a protective order or other remedy; and, in the event that a protective order or other remedy is not obtained, such Shareholder shall furnish only that portion of such information which, in the opinion of its counsel, such Shareholder is legally compelled to disclose and shall exercise its best efforts to obtain reliable assurance that confidential treatment will be accorded any such information so disclosed.

IN WITNESS WHEREOF, this Agreement has been signed by or on behalf of each of the parties hereto, all as of the date first above written.
