The market values shown in column (h) are based on the value of a unit of Hexion Holdings as of December 31, 2018, as determined by Hexion Holdings’ Board of Managers for management equity transaction purposes. In light of differences between the companies, including differences in capitalization, the value of a unit in Hexion Holdings does not necessarily equal the value of a share of the Company’s common stock.

The RDUs are non-voting units of measurement that are deemed for bookkeeping purposes to be equivalent to one common unit of Hexion Holdings. Of the RDUs and options granted in 2011, approximately 50% are “Tranche A RDUs” and options with time-based vesting (subject to acceleration in the event of certain change-in-control transactions) and approximately 50% are “Tranche B and C RDUs” and options with performance-based vesting. The vesting terms of the RDUs and options described in footnotes 3-5 to the table above, in each case, are conditioned on the executive’s continued employment through the vesting dates mentioned above, subject to certain exceptions. With respect to any RDUs that vest as a result of a corporate or change- in-control transaction, such RDUs will be delivered promptly following the vesting date, or a cash payment will be delivered in settlement thereof, depending on the type of transaction. The RDUs and unit options contain restrictions on transferability and other customary terms and conditions.
