The parties to this Agreement hereby agree as follows:

A. The New Trustee agrees to become, with immediate effect, a party to and agrees to be bound by the terms of the Intercreditor Agreement as a Second-Priority Agent, as if it had originally been party to the Intercreditor Agreement as a Second-Priority Agent.

B. The New Indenture, the New Notes, the Security Documents (as defined in the New Indenture), and any related document or instrument executed and delivered pursuant to any of the foregoing shall constitute Second-Priority Documents, and the Security Documents (as defined in the New Indenture) shall constitute Second-Priority Collateral Documents. The Existing Second Lien Notes Collateral Agreement (as defined in the New Indenture), as supplemented by the Joinder and Supplement to Collateral Agreement, dated as of the date hereof, among the New Trustee, the Company, each Subsidiary of the Company party thereto and Wilmington Trust Company, as collateral agent on behalf of the Indenture Secured Parties, shall constitute a Second-Priority Collateral Agreement.

C. The Liens securing the Obligations under the New Notes, the New Indenture and any other document or agreement entered into pursuant thereto granted pursuant to the Security Documents constitute a Second-Priority Lien. The New Trustee and the holders of the New Notes constitute Second-Priority Secured Parties. The Obligations under the New Notes, the New Indenture and any other document or agreement entered into pursuant thereto constitute Future Second-Lien Indebtedness and Second-Priority Claims.

D. The Liens on the Common Collateral securing such Second-Priority Claims shall have equal and ratable priority in all respects to all Liens on the Common Collateral securing any other Second-Priority Claims on the terms set forth in the Intercreditor Agreement and shall be junior to all Liens on the Common Collateral securing any Senior Lender Claims on the terms set forth in the Intercreditor Agreement.

E. So long as the Discharge of Senior Lender Claims has not occurred, the Common Collateral or proceeds thereof received in connection with the sale or other disposition of, or collection on, the Common Collateral upon the exercise of remedies shall be applied by the Intercreditor Agent ratably to the Senior Lender Claims and, with respect to each class of Senior Lender Claims, in such order as is specified in the relevant Senior Lender Documents until the Discharge of Senior Lender Claims has occurred. Upon the Discharge of Senior Lender Claims, the Intercreditor Agent shall deliver promptly to the Second-Priority Designated Agent any Common Collateral or proceeds thereof held by it in the same form as received, with any necessary endorsements or as a court of competent jurisdiction may otherwise direct, to be applied by the Second-Priority Designated Agent ratably to the Second-Priority Claims and, with respect to each class of Second-Priority Claims, in such order as specified in the relevant Second-Priority Documents.

F. The New Trustee confirms that its address for notices pursuant to the Intercreditor Agreement is as follows:

Wilmington Trust Company

Corporate Capital Markets

1100 North Market Street

Wilmington, DE 19801-1615

Facsimile: 302-636-4145

Attention: Hexion Administrator

G. Each party to this Agreement (other than the New Trustee) confirms the acceptance of the New Trustee as a Second-Priority Agent for purposes of the Intercreditor Agreement.

H. The Trustee is designated as the Second-Priority Designated Agent. Except as expressly provided herein, in the Intercreditor Agreement or in any Second-Priority Documents, the New Trustee is acting in the capacity of Second-Priority Agent solely with respect to the Second-Priority Claims owed to the New Trustee and the holders of the New Notes issued pursuant to the New Indenture. For the avoidance of doubt, the provisions of Article VII of the New Indenture applicable to the New Trustee thereunder shall also apply to the New Trustee acting under or in connection with the Intercreditor Agreement.

I. This Agreement shall be construed in accordance with and governed by the laws of the State of New York.

J. This Agreement may be executed in counterparts, each of which shall constitute an original but all of which when taken together shall constitute a single contract. Delivery of an executed signature page to this Agreement by facsimile transmission shall be as effective as delivery of a manually signed counterpart of this Agreement.
