Rollover Shares, to the “Merger Consideration” (as defined in the Merger Agreement).  In particular, you would be entitled to the Merger Consideration in exchange for each Rollover Share (the aggregate such amount with respect to the Rollover Shares, the “ Rollover Share Merger Consideration ”).  You would also be entitled to the same consideration for shares you received pursuant to an election, prior to the Closing, to exercise some or all of the Rollover Options (the aggregate such amount with respect to the Rollover Options, the “ Rollover Option Merger Consideration ” and, with the Rollover Share Merger Consideration, the “ Rollover Merger Consideration ”).  By completing the Acceptance Form below, you agree (i) not to exercise the Rollover Options and (ii) to contribute your Rollover Shares to Newco.  Newco agrees to accept your Rollover Shares and assume and adjust your Rollover Options as provided herein.  This rollover will occur as set forth below in “Sale and Purchase of Newco Equity; Rollover Mechanics”, and you hereby agree that as a result you will not be entitled to receive any Rollover Merger Consideration.

2.              Sale and Purchase of Newco Shares; Rollover Mechanics .  By completing and returning the Acceptance Form below, you agree to, immediately prior to the Closing, contribute your Rollover Shares to Newco and agree to forego any Rollover Share Merger Consideration to which you would otherwise have been entitled absent an election to invest in the Shares.  The Rollover Shares so contributed will be canceled and retired without any conversion thereof or payment or distribution thereon, as set forth in Section 2.1(b) of the Merger Agreement.  Additionally, pursuant to the terms of the Option Grant Agreements, you will, immediately prior to the Closing, cease to have any rights with respect to your Rollover Options including any Rollover Option Merger Consideration to which you would otherwise have been entitled absent the Committee Determination and your agreement not to exercise the Rollover Options.  The Rollover Options will be converted into the Newco Options without any payment or distribution thereon.

In exchange for the Rollover Shares, you will receive such number of Shares having an aggregate value equal (based on the valuation and capitalization set forth in Schedule I) to the aggregate value of the Rollover Shares immediately prior to the Closing as indicated on the Acceptance Form.  As soon as practicable following the Closing, you will either become the holder of record or receive physical certificates of the Shares.

3.              Rollover Share Certificates; Assumption and Adjustment of the Rollover Options .  With respect to the Rollover Shares, you hereby authorize NMG to take such action as may be necessary to cause the Rollover Shares to be rolled over.

You agree that you will not exercise the Rollover Options prior to the Closing.  Newco agrees to assume the Rollover Options on their current terms and conditions, except that:

(a)    the Newco Options will be fully vested at all times, except as provided in Section 7(b) below;

(b)    the Newco Options will be exercisable for Shares;

(c)    the exercise price per Share of each Newco Option will equal the lesser of (i) 25% of the fair market value of a Share, or (ii) the percentage of the fair market value of a Share that equals the ratio of the exercise price per NMG share of such option to the Merger Consideration;

2

(d)    the number of Shares underlying each Newco Option shall be as set forth in Schedule I; and

(e)    at least 10 days prior to the termination or expiration of any Newco Option for any reason, if there is not a Public Market (as defined in the Stockholders’ Agreement) for the Shares, Newco will permit you to exercise any such vested Newco Options through net-physical settlement (i.e., by delivery of Shares net of the number of Shares having a Fair Market Value (as defined in the Stockholders’ Agreement, defined below) equal to the applicable exercise price and applicable withholding taxes at the minimum statutory rate), unless (i) Newco’s independent auditors determine that net-physical settlement of any such Newco Options would produce less-favorable accounting consequences for Newco or its affiliates than if you paid the exercise price for any such vested Newco Options in cash (other than those that would have an immaterial effect) or (ii) Newco receives advice from counsel, in accordance with Section 10 below, that such net-physical exercise would result in a penalty under Section 409A of the Internal Revenue Code of 1986, as amended (the “ Code ”).  If, in accordance with this paragraph, you are entitled to exercise Newco Options through net-physical exercise, Fair Market Value will be determined as set forth in the Stockholders’ Agreement, including any right to an Outside Appraisal (as defined therein).

4.              Acceptance and Closing; Conditions .  You may accept this offer and the terms of this Agreement by completing and returning the Acceptance Form below, in which case the closing of the acquisition of your Newco Equity will occur immediately after the Closing.  This offer is conditioned upon the occurrence of the Closing.  If the Closing does not occur on or before October 17, 2005 (the “ Closing Deadline ”), this Agreement will be canceled and you will have no rights with respect hereto and any Rollover Shares that you have transferred or cash payment that you have made pursuant to Section 3 will be returned to you; provided , that if Newco determines on or before the Closing Deadline and in good faith that the Closing is likely to occur on or before October 31, 2005, the Closing Deadline shall automatically be extended to October 31, 2005.

5.              Limitation .  Newco, in its discretion, may limit the number of Shares that you may purchase, and therefore may choose not to accept the full amount of your investment election with respect to your Rollover Shares.  Rollover Shares not so accepted pursuant to the preceding sentence will be treated in accordance with the provisions of the Merger Agreement.

6.              Vesting .  Your Shares when issued will be fully vested.

7.              Stockholders’ Agreement; Certain Other Agreements .

(a)    By completing and returning the Acceptance Form below, you agree to become a party to the Management Stockholders’ Agreement, a copy of which is attached hereto as Annex A, as may be amended from time to time in accordance with its terms (the “ Stockholders’ Agreement ”) and you will be subject to the terms and conditions thereof with respect to your Shares; provided that the Shares shall not be subject to the call right in Section 3(b).  Newco agrees that it will, and that it will cause the Majority Stockholder (as defined below) to, also become a party to the Stockholders’ Agreement.

3

(b)    In addition to the terms and conditions of the Stockholders’ Agreement, with respect to Newco Options for a total of 1,810.4095 Shares, as determined pursuant to Schedule I (the “ Excess Options ”), in the event that, on or before the first anniversary of the Closing, your employment with NMG or any of its affiliates terminates as a result of NMG or its affiliates terminating your employment for Cause (as such term is defined in your employment agreement with NMG, dated October 6, 2005 (your “ Employment Agreement ”)), your voluntary resignation other than for your retirement or for Good Reason (as such term is defined in your Employment Agreement), Newco and its affiliates shall have the right, at any time until the earlier of (x) the fifth anniversary of the Closing or (y) a Public Market (as such term is defined in the Stockholders’ Agreement) exists for the Shares, to, at any time after delivery of a notice to you or your estate:

i.             Cancel each Excess Option in exchange for a cash payment for each Share underlying such Excess Option being canceled equal to the difference between (1) the lesser of (A) Fair Market Value of the Share (as such term is defined in the Stockholders’ Agreement and subject to any right to seek an Outside Appraisal in accordance with the Stockholders’ Agreement) underlying such Excess Option and (B) $1,445 (whichever such amount applies, the “ Excess Share Buyout Price ”) and (2) the per Share exercise price of such Excess Option being canceled; or

ii.            Purchase any or all Shares you hold as a result of the exercise of any or all of the Excess Options for the Excess Buyout Price.

(c)    If, after the Closing Date but prior to the existence of a Public Market, Newco or Newton Holding, LLC (“ Newton LLC ”) proposes to issue additional shares of common stock of Newco or membership interests of Newton LLC (in each case with the exception of any issuance in connection with any merger, acquisition or similar corporate event or to employees pursuant to an employee incentive plan), Newco or Newton LLC, as applicable, shall provide written notice (the “ Issuance Notice ”) to you of such anticipated issuance no later than ten (10) days prior to the anticipated issuance date.  The Issuance Notice shall set forth the material terms and conditions of the issuance, including the proposed purchase price for the new shares of common stock of Newco or membership interests of Newton LLC.  You shall have the right, upon receipt of the Issuance Notice, to purchase additional shares of common stock of Newco up to your pro rata portion (based on the number of shares of common stock of Newco you own or subject to vested stock options you hold immediately prior to such issuance), at the price and on the terms and conditions specified in the Issuance Notice by delivering an irrevocable written notice to Newco no later than five (5) days before the anticipated issuance date, setting out the number of new shares of common stock of Newco for which the right is exercised; provided that if the issuance is of membership interests in Newton LLC, your pro rata portion shall be calculated as if the shares of common stock of Newco held by you and all other holders of the shares of common stock of Newco (other than Newton LLC) were converted into membership interests in Newton LLC and you held such membership interests together with all of the holders of membership interests in Newton LLC on the date the notice was delivered.  If you fail to exercise all or a portion of your preemptive rights, Newco or Newton LLC, as applicable, shall be permitted to complete the proposed issuance without any further notice or action related to the rights provided in this Section 7(d).  In the event that Newton LLC proposes to issue new membership interests, Newton LLC and Newco may determine, in their sole discretion, to permit

4

you to exercise your preemptive rights to purchase membership interests in Newton LLC rather than additional shares of common stock of Newco.

8.              Tax Reporting .  It is intended that the rollover of the Rollover Shares and Rollover Options contemplated herein shall be treated as a tax-free transfer under the Code.

All discussions of U.S. federal tax considerations in this document have been written to support the marketing of the Shares.  Such discussions were not intended or written to be used, and cannot be used by any taxpayer, for the purpose of avoiding U.S. federal tax penalties.  You should consult your own tax advisers in determining the tax consequences of the rollover and of holding the Shares, including the application to your particular situation of the U.S. federal tax considerations discussed herein, as well as the application of state, local, foreign, or other tax laws.
