Explanation of Responses:

1. Each Performance Share represents a contingent right to acquire one Common Share.

2. Each Performance Share represents the right to receive one share of 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.

3. Each Performance Share represents the right to receive one share of our Common Stock subject to a performance goal that is based on a calculated return on equity versus a pre-determined target return on equity of 20%. The return on equity is calculated by dividing earnings before interest and income tax from continuing operations over the performance period by ending shareholders' equity over the performance period ("ROE"). If our ROE for the performance period equals 20%, then 50% of the shares will be issued, and if our ROE for the performance period equals or exceeds 24%, then 100% of the shares will be issued. If our ROE for the performance period is greater than 20% but less than 24%, then the number of shares to be issued would be interpolated based on the terms of the agreement.
