Explanation of Responses:
1. These shares were not sold, but were withheld by ION Geophysical Corporation ("ION") upon the vesting of restricted stock shares to satisfy tax withholding obligations.
2. These were subscription rights acquired in the ION's Rights Offering which commenced on March 23, 2021, which rights the reporting person exercised to purchase a principal amount of ION's 8.00% Senior Secured Second Priority Convertible Notes due 2025. ION issued one non-transferable subscription right for each share of Common Stock held on the March 22, 2021 record date and each subscription entitled the holder to purchase $2.78 principal amount of ION's Notes.
3. These are ION's 8.00% Senior Secured Second Priority Convertible Notes due 2025 that were directly acquired by the reporting person as a result of his exercise of subscription rights which were issued to him in ION's Rights Offering.
