## Summary of Plans 

On August 8, 2019, the Board of Directors of Hexion Holdings approved the Hexion Holdings Corporation 2019 Omnibus Incentive Plan (the “2019 Incentive Plan”), whereby Hexion Holdings is reserving shares of Class B Common Stock, par value $0.01 per share, representing 10% of Hexion Holding’s fully diluted equity as of the date of approval of the 2019 Incentive Plan, for issuance to employees, directors, and other key service providers in connection with stock options, restricted stock units, performance-based stock units and other equity-based awards (such as performance stock units) to be awarded from time to time as the Board determines. The restricted and performance stock units are deemed to be equivalent to one share of common stock of Hexion Holdings. The awards contain restrictions on transferability and other typical terms and conditions. 

## Restricted Stock Units - Employee Grants 

In September 2019, Hexion Holdings granted RSUs that time vest over three years with an aggregate grant date fair value of approximately $16. The fair value was determined using the estimated aggregate fair value of equity per share on the grant date. Compensation cost is recognized equally over the 3 year service period. For certain retirement eligible associates, the stock-based compensation cost is accelerated according to the plan documents. Upon vesting, RSUs are settled in shares at the end of the three year vesting period. As of December 31, 2020, a total of 344,700 RSUs had vested.
