delivering or filing a Form 3, Form 4 or Form 5 (including amendments thereto)
and agrees to reimburse Gibson, Dunn & Crutcher LLP or Expro Group Holdings
N.V., as applicable, and the attorney-in-fact on demand for any legal or other
expenses reasonably incurred in connection with investigating or defending
against any such loss, claim, damage, liability or action.
