In lieu of such insurance, prior to the Closing Date each of Momentive and Hexion may purchase a “tail” directors’ and officers’ liability insurance policy and fiduciary liability insurance policy for itself and its current and former directors and officers who are currently covered by the directors’ and officers’ and fiduciary liability insurance coverage currently maintained by either Momentive or Hexion, as the case may be, for up to 300% of the annual premium payable by Momentive or Hexion, as applicable, for such insurance for the year ending December 31, 2009, in which event Holdco shall cease to have any obligations under the first sentence of this Section 5.5(b). Holdco shall cause such policies to be maintained in full force and effect, and the obligations thereunder to be honored.

5.6. Hexion Options and Other Equity-Based Awards.

(a) Each option to purchase Hexion Units (a “Hexion Option”) granted under the employee and director equity plans of Hexion (the “Hexion Equity Plans”), whether vested or unvested, that is outstanding immediately prior to the Effective Time shall, at such time, cease to represent a right to acquire shares of Hexion Units and shall be converted, at the Holdco Merger Effective Time, into an option to purchase common units of Holdco (a “Holdco Option”), on the same terms and conditions as were applicable under such Hexion Option (but taking into account any changes thereto, including any acceleration thereof, provided for in the Hexion Equity Plans, in any award agreement or in such Hexion Option by reason of this Agreement or the transactions contemplated hereby). The number of common units of Holdco subject to each such Holdco Option shall be the number of Hexion Units subject to each such Hexion Option multiplied by the Hexion Exchange Ratio, rounded, if necessary, down to the nearest whole common unit of Holdco, and such Holdco Option shall have an exercise price (or base price) per share (rounded up to the nearest one-hundredth of a cent) equal to the per share exercise price (or base price) of such Hexion Option divided by the Hexion Exchange Ratio.

(b) At the Effective Time, each right of any kind, contingent or accrued, to receive Hexion Units or benefits measured by the value of a number of Hexion Units, and each award of any kind consisting of shares of Hexion Units, granted under the Hexion Equity Plans (including restricted equity, restricted equity units, deferred equity units and dividend equivalents), other than Hexion Options (each, a “Hexion Equity-Based Award”), whether vested or unvested, which is outstanding immediately prior to the Effective Time shall cease to represent a right or award with respect to Hexion Units and shall be converted, at the Holdco Merger Effective Time, into a right or award with respect to common units of Holdco (a “Holdco Equity-Based Award”), on the same terms and conditions as were applicable under the Hexion Equity-Based Awards (but taking into account any changes thereto, including any acceleration thereof, provided for in the Hexion Equity Plans, in any award agreement or in such Hexion Equity-Based Award by reason of this Agreement or the transactions contemplated hereby). The number of common units of Holdco subject to each such Holdco Equity-Based Award shall be equal to the number of Hexion Units subject to the Hexion Equity-Based Award, multiplied by the Hexion Exchange Ratio, rounded, if necessary, down to the nearest whole common unit of Holdco. All dividend equivalents credited to the account of each holder of a Hexion Equity-Based Award as of the Holdco Merger Effective Time shall remain credited to such holder’s account immediately following the Holdco Merger Effective Time, subject to adjustment in accordance with the foregoing.

(c) As soon as practicable after the Holdco Merger Effective Time, Hexion shall deliver to the holders of Hexion Options and Hexion Equity-Based Awards appropriate notices setting forth such holders’ rights pursuant to the respective Hexion Plans and agreements evidencing the grants of such Hexion Options and Hexion Equity-Based Awards, and stating that such Hexion Options and Hexion Equity-Based Awards shall be converted into Holdco Options and Holdco Equity-Based Awards, respectively,

-40-

pursuant to this Section 5.6 and shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 5.6 after giving effect to the Mergers and the terms of the Hexion Equity Plans).

(d) Prior to the Holdco Merger Effective Time, Hexion shall take all necessary action for the adjustment of Hexion Options and Hexion Equity-Based Awards under this Section 5.6. Holdco shall reserve for issuance a number of common units of Holdco at least equal to the number of common units of Holdco that will be subject to Holdco Options and Holdco Equity-Based Awards as a result of the actions contemplated by this Section 5.6.

(e) The parties agree and acknowledge that, following the Holdco Merger Effective Time, the obligation to deliver Holdco common units in respect of the Hexion Options and the Hexion Equity-Based Awards that have been converted pursuant to the foregoing provisions of this Section 5.6 shall continue to be an obligation of Hexion (or the Hexion Subsidiary that is a party to the particular Hexion Stock Option or Hexion Equity-Based Award, as the case may be). In connection with an exercise or payment of such a Hexion Option or Hexion Equity-Based Award that has been so converted, it is intended that Holdco shall deliver common units of Holdco to Hexion in order to satisfy Hexion’s (or its Subsidiary’s) obligation to deliver common units of Holdco pursuant to such award. In furtherance of the foregoing, the parties hereto agree to reasonably cooperate to implement agreements and/or other instruments, as the parties may determine, to provide for the delivery of common units of Holdco in connection with the exercise or payment of any such award to the appropriate Hexion entity.

5.7. Momentive Stock Options and Other Equity-Based Awards.

(a) Each option to purchase shares of Momentive Common Stock (a “Momentive Stock Option”) granted under the employee and director stock plans of Momentive (the “Momentive Stock Plans”), whether vested or unvested, that is outstanding immediately prior to the Effective Time shall, at such time, cease to represent a right to acquire shares of Momentive Common Stock and shall be converted, at the Holdco Merger Effective Time, into a Holdco Option, on the same terms and conditions as were applicable under such Momentive Stock Option (but taking into account any changes thereto, including any acceleration thereof, provided for in the Momentive Stock Plans, in any award agreement or in such Momentive Stock Option by reason of this Agreement or the transactions contemplated hereby). The number of common units of Holdco subject to each such Holdco Option shall be the number of shares of Momentive Common Stock subject to each such Momentive Stock Option multiplied by the Momentive Exchange Ratio, rounded, if necessary, down to the nearest whole common unit of Holdco, and such Holdco Option shall have an exercise price (or base price) per share (rounded up to the nearest one-hundredth of a cent) equal to the per share exercise price (or base price) of such Momentive Stock Option divided by the Momentive Exchange Ratio.

(b) At the Effective Time, each right of any kind, contingent or accrued, to receive shares of Momentive Common Stock or benefits measured by the

-41-

value of a number of shares of Momentive Common Stock, and each award of any kind consisting of shares of Momentive Common Stock, granted under the Momentive Stock Plans (including restricted stock, restricted stock units, deferred stock units and dividend equivalents), other than Momentive Stock Options (each, a “Momentive Stock-Based Award”), whether vested or unvested, which is outstanding immediately prior to the Effective Time shall cease to represent a right or award with respect to shares of Momentive Common Stock and shall be converted, at the Holdco Merger Effective Time, into a Holdco Equity-Based Award, on the same terms and conditions as were applicable under the Momentive Stock-Based Awards (but taking into account any changes thereto, including any acceleration thereof, provided for in the Momentive Stock Plans, in any award agreement or in such Momentive Stock-Based Award by reason of this Agreement or the transactions contemplated hereby). The number of common units of Holdco subject to each such Holdco Equity-Based Award shall be equal to the number of shares of Momentive Common Stock subject to the Momentive Stock-Based Award, multiplied by the Momentive Exchange Ratio, rounded, if necessary, down to the nearest whole common unit of Holdco. All dividend equivalents credited to the account of each holder of a Momentive Stock-Based Award as of the Holdco Merger Effective Time shall remain credited to such holder’s account immediately following the Holdco Merger Effective Time, subject to adjustment in accordance with the foregoing.

(c) As soon as practicable after the Holdco Merger Effective Time, Holdco shall deliver to the holders of Momentive Stock Options and Momentive Stock-Based Awards appropriate notices setting forth such holders’ rights pursuant to the respective Momentive Stock Plans and agreements evidencing the grants of such Momentive Stock Options and Momentive Stock-Based Awards, and stating that such Momentive Stock Options and Momentive Stock-Based Awards shall be converted into Holdco Options and Holdco Equity-Based Awards, respectively, pursuant to this Section 5.7 and shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 5.7 after giving effect to the Mergers and the terms of the Momentive Stock Plans).

(d) Prior to the Holdco Merger Effective Time, Momentive shall take all necessary action for the adjustment of Momentive Stock Options and Momentive Stock-Based Awards under this Section 5.7. Holdco shall reserve for issuance a number of common units of Holdco at least equal to the number of common units of Holdco that will be subject to Holdco Options and Holdco Equity-Based Awards as a result of the actions contemplated by this Section 5.7.

(e) The parties agree and acknowledge that, following the Holdco Merger Effective Time, the obligation to deliver Holdco common units in respect of the Momentive Stock Options and the Momentive Stock-Based Awards that have been converted pursuant to the foregoing provisions of this Section 5.7 shall continue to be an obligation of Momentive (or the Momentive Subsidiary that is a party to the particular Momentive Stock Option or Momentive Stock-Based Award, as the case may be). In connection with an exercise or payment of such a Momentive Stock or Momentive Stock-Based Award that has been so converted, it is intended that Holdco shall deliver common units of Holdco to Momentive in order to satisfy Momentive’s (or its Subsidiary’s)

-42-

obligation to deliver common units of Holdco pursuant to such award. In furtherance of the foregoing, the parties hereto agree to reasonably cooperate to implement agreements and/or other instruments, as the parties may determine, to provide for the delivery of common units of Holdco in connection with the exercise or payment of any such award to the appropriate Momentive entity.
