Reflects OceanFirst securities acquired pursuant to the terms of the Merger Agreement and agreements contemplated thereby. The reported shares were withheld to satisfy the tax liability in connection with the vesting of Flushing restricted stock awards pursuant to the Merger Agreement. No shares were sold.
