NOW THEREFORE , in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

The initial term of the Executive’s employment will commence on the Effective Date, and end on the fifth anniversary of the Effective Date (the “ Initial Employment Period ”), unless terminated earlier pursuant to Section 3 of this Agreement; provided, however, that as of the expiration date of each of (i) the Initial Employment Period and (ii) if applicable, any Renewal Period (as defined below), the Employment Period will automatically be extended for a one-year period (each, a “ Renewal Period ”), unless either party gives at least ninety (90) days written notice prior to such expiration date of its intention not to renew the Employment Period (the Initial Employment Period and each subsequent Renewal Period shall constitute the “ Employment Period ”). A notice of nonrenewal by the Company shall be treated as termination without Cause as of the end of the then-applicable Employment Period. The Employment Period shall automatically end upon termination of the Executive’s employment for any reason. Upon the Executive’s termination of employment with the Company for any reason, he shall immediately resign all positions (including directorships) with the Company or any of its subsidiaries or affiliates.

(a) Position . During the Employment Period, the Executive shall serve as the Chief Executive Officer of the Company and perform such duties and responsibilities customary to such position. The Executive shall report to the Board of Directors of the Company (the “ Board ”). The Executive shall also serve as a member of the Board and as a member of the Board of Directors of Momentive Performance Holdings Corp. (the “ Parent ” and such Board of Directors, the “ Parent Board ”). At the request of the Company, the Executive shall also serve as an officer of any of its subsidiaries or affiliates without additional compensation. In the event that the Parent becomes an entity whose common stock is publicly traded or an operating company, the Executive shall also be chief executive officer of Parent.

(b) Duties . During the Employment Period, the Executive agrees to devote substantially all of his business time and efforts to the business and affairs of the Company. Notwithstanding the foregoing, nothing herein shall prohibit the Executive from (i) serving on civic or charitable boards or committees, (ii) delivering lectures or fulfilling speaking engagements and (iii) managing personal investments, so long as such activities do not interfere with the performance of the Executive’s responsibilities hereunder. With the consent of the board, Executive may serve on the Board of for profit entities.

(c) Compensation .

(i) Base Salary . During the Employment Period, the Executive shall receive an initial annual base salary in an amount equal to $650,000 (as may be increased from time to time, the “ Annual Base Salary ”), which shall be paid in accordance with the customary payroll practices of the Company (but no less infrequently than in equal monthly installments). The Base Salary will be reviewed by the Board or the Compensation Committee of the Board (the “ Compensation Committee ”) or its designee annually for increase (but not for decrease). The Base Salary, as then increased, will be the “Base Salary” for all purposes of this Employment Agreement.

(ii) Bonuses . During the Employment Period, the Company shall establish an annual bonus plan for each fiscal year of the Company (the “ Plan ”) pursuant to which the Executive will be eligible to receive a target annual bonus in an amount equal to 100 percent of the Annual Base Salary (the “ Bonus ”), which Bonus may be higher or lower than this percentage based on actual performance. With respect to the Company’s 2007 fiscal year, the Executive will be entitled to receive a Bonus on a pro-rated basis equal to the product of (x) the Bonus which otherwise would have been earned by Executive for the Company’s 2007 fiscal year absent pro-ration, times (y) a fraction, the numerator of which is the number of days in the Company’s 2007 fiscal year from and after the Effective Date, and the denominator of which is 365; provided that such Bonus shall in no event be less than 50 percent of the Base Salary earned by the Executive for the Company’s 2007 fiscal year. The Board or the Compensation Committee will administer the Plan and establish performance objectives for each year. The Executive’s Bonus will be determined based on the achievement of such performance objectives for the applicable year (the majority of which will be based on quantitative objectives, with a small portion to be based on qualitative objectives), provided that the Board and/or the Compensation Committee may provide discretionary bonuses to the Executive under the Plan. Unless the Executive is employed on the last day of the applicable performance period, the Executive will not be entitled to receive the Bonus upon the Company’s achievement of the specified performance objectives (subject to Section 4 of this Agreement). Except as provided for in Section 4 of this Agreement, the Bonus shall be paid on or prior to March 15 following the end of the applicable fiscal year provided that the Board or Compensation Committee finally determines (x) that the Company has achieved the applicable performance objectives and (y) the amount of Bonus that shall be paid to the Executive for the applicable Plan year.
