The number of shares reported in this column has been reduced by the number of phantom shares issued pursuant to the Core Laboratories, Inc. Deferred Compensation Plan. Those phantom shares entitle the reporting person to receive a cash settlement only and no common shares will be issued. The tax-offset right was granted in connection with the award of restricted shares issued pursuant to an Executive Share Matching Restricted Share Agreement. The tax-offset right entitles the reporting person to receive, upon vesting of the restricted shares, common shares the value of which is equal to the tax obligation incurred in connection with the event, including the tax-offset payment. /s/ John D.
