Item 5.02  Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers
As previously announced, on March 2, 2011, the Board of Supervisory Directors of Core Laboratories N.V. (the "Company") approved a Board Succession Plan whereby one non-employee supervisory director will be replaced with a new supervisory director each year for the next six years.  In order to avoid unintended forfeiture of previously made or approved restricted stock grants to the non-employee directors that are affected by the Board Succession Plan, the Supervisory Board has approved certain amendments or modifications to the related award agreements as described below.
On March 30, 2011, the Supervisory Board approved amendments to the award agreements for restricted performance share awards ("PSAPs") previously issued to non-employee directors in 2008, 2009 and 2010 to provide that the PSAPs will not be forfeited if the supervisory director ceases to be a supervisory director as a result of the Board Succession Plan.  The other vesting requirements, including performance requirements and vesting period, will continue to apply to the PSAPs.
On March 30, 2011, the Supervisory Board also approved similar modifications to the award agreements for the restricted stock awards (the "RSAPs") approved at its meeting on February 8, 2011 and issued effective April 1, 2011.  The RSAP awards consist of restricted shares in the amount of $150,000 divided by the closing stock price of the Company on March 31, 2011. The related award agreements were modified prior to issuance to provide that the RSAPs will not be forfeited if the supervisory director ceases to be a supervisory director as a result of the Board Succession Plan.  The other vesting requirements, including the three-year vesting period, will continue to apply to the RSAPs.
In connection with the amendments described above, the Supervisory Board also approved an RSAP award to the supervisory director to be elected at the Company's 2011 annual meeting to replace Mr. Jacobus Schouten pursuant to the Board Succession Plan.  This award will be in an amount equal to the number of restricted shares issued to existing non-employee directors, including Mr. Schouten, on April 1, 2011.
