Footnote F2

At the Effective Time, each restricted stock unit ("RSU") held by the reporting person was surrendered in exchange for, subject to any withholding, a cash payment equal to the Consideration in respect of each Common Share underlying such RSU.

Footnote F4

Each Performance Based Restricted Stock Unit represents a contingent right to receive one share of STKL common stock.

Footnote F5

Represents the number of performance share units ("PSUs") held by the reporting person that was determined pursuant to the Arrangement Agreement to be entitled to Consideration in the Arrangement.
