The non-prevailing party in any proceeding shall reimburse the prevailing party for the reasonable costs and expenses, including attorneys' fees incurred. 8. COOPERATION. Executive further agrees that, subject to reimbursement by OHM of reasonable out-of-pocket costs and expenses including reasonable costs and expenses of Executive's counsel, if any, Executive will fully cooperate with OHM and its counsel with respect to any matter (including litigation, investigation or governmental proceeding) which relates to matters with which Executive was involved during the term of employment with OHM or during any period under this Agreement pursuant to which Executive received benefits from OHM.
