Exhibit 10.31

SEVERANCE PAY AGREEMENT AND RELEASE OF ALL CLAIMS

This Transition & Severance Pay Agreement and Release of
All Claims (Agreement) is entered into between Sarah R. Coffin (Associate or You) and Hexion Specialty Chemicals, Inc. (Company).

Until February 15, 2009 (Termination Date), you will be an active employee of the Company and remain on the Companys payroll. Accordingly, you agree to perform all job-related duties and
functions that may be assigned to you from time-to-time by the Company;



|1. | Considerations:
|-- | ---------------

Severance Payments

The Company agrees to pay you $400,000 as severance. This amount is equal to fifty-two weeks (52) weeks of your current base
salary. Severance payments will be made to you in bi-weekly installments, subject to all applicable legal deductions and withholdings. Deductions for cash advances and other monies due the Company will be made from these payments.

The severance period for which these severance payments will be made will begin February 16, 2009 and end on February 15, 2010 (Severance
Period).

Transition Payment

In consideration for the final settlement of the agreement, the company will pay you an additional lump sum of $126,000 by February 20, 2009. The employee will not be entitled to any other payments and all other
entitlements shall be considered forfeited.

Health Benefit Continuation

The Company shall pay you on or as soon as practicable after February 16, 2009, a cash lump sum intended to cover the approximate cost of the
Companys portion of the premiums necessary to continue your medical care coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act (COBRA), for a period of twenty-six (26) weeks following February 16,
2009, at the same or reasonably equivalent coverage for you (and, if applicable, your eligible dependents) as in effect immediately prior to the Termination Date. You may elect to continue health care coverage pursuant to COBRA (up to the maximum
period of COBRA coverage); provided that you shall be required to pay any and all premiums associated therewith directly to the third party COBRA Administrator.

The Company will gross-up this payment to allow for Federal Income Tax withholding (generally withheld at a rate of 25%). However, due to the complexity of the various state and local taxing jurisdictions, the amount
of this lump sum payment may not cover all required tax withholdings. This payment will be based on the COBRA rates in effect at the time of your separation. You will be responsible for any subsequent increases in COBRA rates.



---

If you elect to extend your healthcare coverage through COBRA:



| |  |  | Your coverage will be retroactive to your termination date
| | - |  | ----------------------------------------------------------



| |  |  | You will be sent monthly bills for your COBRA premiums from the third party COBRA Administrator.
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | The Severance Period is considered to be part of the 18 months COBRA eligibility.
| | - |  | ---------------------------------------------------------------------------------

Vacation

You will receive payment
for all accrued, but unused vacation through your termination date. After this date, you will not accrue or earn any additional paid vacation.

Outplacement Support

The Company has arranged, at its own expense, a program of 12 months Executive outplacement support
for you. Additional information on these services will be provided to you in a separate attachment.

All Other Company Sponsored Benefit
Plans

Unless specified in this Agreement, you will cease participation in and/or accruing benefits under Company sponsored benefit
plans as of your termination date.



|2. | Eligibility for Considerations: You understand that, to be eligible for any of the considerations under this Agreement, you must be actively employed and working through the
date on which the Company releases you from work. You may not terminate before then or be unavailable for active work due to leave status (disability, workers compensation, or personal) on your termination date. Should you be on such leave at
your termination date, you will be covered by the terms and conditions of that particular status for its duration.

|3. | Release of All Claims: In exchange for the monies and benefits given to you under this Agreement, you give up the right to bring any claims whatsoever

local laws regarding rights or claims relating to employment and common law, including but not limited to, any claim for breach of an oral, implied or written employment contract; negligent or intentional misrepresentations; wrongful discharge;
defamation; negligent or intentional infliction of emotional distress; and/or violation of public policy. By signing this Release and Pay Agreement, you have waived your right to file any claim with the U.S. Equal Employment Opportunity Commission
