Explanation of Responses:

1. These Common Shares were acquired pursuant to the Core Laboratories, Inc. Profit Sharing and Retirement Plan (the "401(k) Plan") or pursuant to the Core Laboratories, Inc. Deferred Compensation Plan (the "Deferred Comp Plan"), as the case may be, on various dates at various prices per share. The number of Common Shares shown in columns 4 and 5 of Table 1 is based on an allocation of the aggregate number of Common Shares acquired by the trustee under the 401(k) Plan or the Deferred Comp Plan, as the case may be, for the benefit of the plan participants who elected to make intra-plan transfers into the Common Share fund under the 401(k) Plan or the Deferred Comp Plan, as the case may be, at approximately the same time (pro rata, based on the dollar amount of each such participant's intra-plan transfer into the Common Share fund, rounding up or down to the nearest whole share).

2. The information reported herein is based on plan statements; the amount in Column 4 is for the particular plan transaction and the amount in Column 5 is for the combined plans.

3. This option is scheduled to become exercisable in 25% increments on each anniversary date.

4. This option is scheduled to become exercisable in 50% increments on each anniversary date.

5. Represents a grant of performance restricted shares which represent the right to receive our Common Shares in the future based on the performance of our Common Shares. None of these awards will vest unless our Common Shares perform better than the common stock of 50% of the companies comprising the Oil Service Sector Index (OSX) during the three-year period that began on the date of grant. If our Common Shares perform better than 75% of the companies comprising this index during such period, then all of the performance restricted shares will vest. If our common shares perform better than between 50% and 75% of the companies comprising the index, then an interpolated percentage of between 20% and 100% of the performance restricted shares will vest at the end of the three-year period. The executive will not receive dividends on or be entitled to vote the underlying Common Shares unless and until they have been issued at the end of the vesting period.
